• Если задача скучная: пойду в субботу в свое любимое кафе и заполню налоговую декларацию за чашкой какого-нибудь экзотического кофе, а заодно и понаблюдаю за жизнью вокруг.
• Задача чрезвычайно рутинная, создается ощущение бесплодности усилий: я прихожу в то же кафе, но кроме данных для работы над декларацией у меня есть с собой книга. Я устанавливаю таймер на смартфоне и работаю над налогами ровно 30 минут. Свыше 30 минут я работаю только в том случае, если дело пошло и я чувствую, что в состоянии продолжать.
• Сложная задача: проведу исследование, чтобы точно выяснить, какие шаги мне нужно предпринять и какие документы собрать. Пойду в кафе во время моего биологического прайм-тайма, когда у меня больше энергии.
• Задача неструктурированная или неоднозначная: проведу исследование по соответствующей тематике и на этой основе составлю подробный план всех необходимых шагов.
• Задача не имеет личностного смысла: ищу позитивные стороны. Например, если можно получить налоговое возмещение, то я стараюсь думать о его возможном размере и составляю список, на что потрачу полученные деньги.
• При выполнении задачи невозможно испытывать удовлетворение от самого процесса, не возникает никаких промежуточных стимулов: за каждые 15 минут, которые я провожу, работая над налогами, я разрешаю себе потратить два с половиной доллара на какой-нибудь каприз или награждаю себя каким-то другим значимым образом за выполнение определенного этапа.

If you want to see more high quality blog posts, then I highly recommend taking actions to help promote and encourage them. Sign up for a mailing list or subscribe to an RSS feed when you find a blog that consistently produces quality material.
Post new or old content on Hacker News, Reddit, Lobsters, Twitter, and other communities where you think they would be a good fit.
Upvote and retweet quality content that you run across, and flag stuff that's blatantly marketing spam. Leave comments on the blog or reach out to the author over email.
Even as a single individual, these sort of actions have a much bigger impact than you might expect.

"No really, what is your process."

[2019-09-21] Shtetl-Optimized » 2013 » March Preskill§

https://www.scottaaronson.com/blog/?m=201303 

I got back a couple days ago from John Preskill‘s 60th birthday symposium at Caltech.  To the general public, Preskill is probably best known for winning two bets against Stephen Hawking.  To readers of Shtetl-Optimized, he might be known for his leadership in quantum information science, his pioneering work in quantum error-correction, his beautiful lecture notes, or even his occasional comments here (though these days he has his own group blog and Twitter feed to keep him busy).  I know John as a friend, colleague, and mentor who’s done more for me than I can say.

[2019-09-08] ELI5: What makes us get a ‘Stitch’ in our sides when we run too quickly? /r/explainlikeimfive§

Believe it or not, the real answer is, 'we don't know'! The most common answer is that the jerking nature of running pulls on the ligaments tying the organs in our stomachs to our bones - but this can't be the whole answer, as people get stitches while swimming!
Another possibility is that as the heart rate increases, the blood pressure into the liver and spleen increases, making them bigger, squeezing some blood vessels partially closed. This causes some places to not get enough oxygen.
A third has to do with breathing. If a runner doesn't breathe deeply, part of their lungs don't get fresh air. As the blood is depleted in oxygen when it gets back to the lungs, the parts of the lungs with stale air in them aren't getting enough oxygen, and getting too much carbon dioxide, causing pain.

Boring Advice Repository - LessWrong 2.0§

  • When in need of a conversation topic, ask a question about the other person’s life. Anything about their life. (If I can’t think of something else, I ask about weekend plans.) Listen for what part of their answer they’re most interested in. Ask followup questions about that thing. Repeat as necessary. People like to talk about themselves. This cuts awkward silences down to nothing and makes people like you. I’ve also learned all sorts of fascinating things about my acquaintances.
  • Try to live close to where you work. Failing that, try to work close to where you live. Commuting takes a lot of time and you don’t get paid for it. Alternative: commute effectively. Taking a train to NYC from Long Island I get almost 2 hours to read/watch lectures or entertainment. Some days these are 2 best hours of the day.
  • If you are trying to do X, surround yourself with people who are also doing X. Takes much less willpower to keep doing it.
  • The 80/20 rule is especially true for cleaning. Better to get it 80% clean twice as often than 99% clean half as often.

[2019-04-18] Is it more environmentally friendly to wash your dishes? Or use paper plates instead? What is the real carbon footprint left by wasted water, vs paper plates? /r/askscience [[recycling]] [[environment]]§

I've wondered about this too and I found it very hard to find good information.  It undoubtedly depends on where you live because the relative costs of water and trash removal vary so much depending where you live.  I think in water-scarce regions of Arizona, Nevada and Southern California, there is a decent argument to be made that disposable paper plates are an environmentally sensible alternative to washing lots of ceramic dinner plates. But it would very much depend on local costs and where the disposed of plates go.  Are they buried in a landfill or burned to make electricity?  How far do they have to be hauled in their lifetime?  What happens to the wastewater?

There is no black and white in these types of situations.  Either scenario is OK and if you really want to figure out how to minimize your carbon footprint, an accurate accounting depends on your local water and electricity rates.

Latest news - version 1.1.4
… read about the new version — be sure: it is rewarding ;-)
Needs at least Java 8 - but works on Java 10 and 11
No longer needs setup - download and use it.
Sikuli is God's Eye
… in Huichol Indian culture: the power to see and understand things unknown.
(Thanks for the picture showing a Sikuli)
Sikuli was started somewhen in 2009 as an open-source research project at the User Interface Design Group at MIT by Tsung-Hsiang Chang and Tom Yeh.
Both left the project at Sikuli-X-1.0rc3 during 2012, when I decided to take over development and support and name it SikuliX.
What is SikuliX?
SikuliX automates anything you see on the screen of your desktop computer running Windows, Mac or some Linux/Unix. It uses image recognition powered by OpenCV to identify and control GUI components. This is handy in cases when there is no easy access to a GUI's internals or the source code of the application or web page you want to act on.

Despite the formalization of Standard Russian, some nonstandard dialectal features (such as fricative [ɣ] in Southern Russian dialects) are still observed in colloquial speech.

http://worrydream.com/#!/ClimateChange

These are lists of proverbs. Little action items, mostly dequantified, entirely decontextualized. How significant is it to “eat wisely” and “trim your waste”? How does it compare to other sources of harm? How does it fit into the big picture? How many people would have to participate in order for there to be appreciable impact? How do you know that these aren’t token actions to assauge guilt?§

[2019-04-19] exactly my concerns!§

[2019-04-19] Climate change is too important for us to operate on faith. Citizens need and deserve reading material which shows context — how significant suggested actions are in the big picture — and which embeds models — formulas and algorithms which calculate that significance, for different scenarios, from primary-source data and explicit assumptions.§

[2019-04-19] Models§

If data is hard to find, models are virtually impossible.
What’s a formula for estimating the power consumption of a home’s lighting?
What’s an algorithm that models the activity pattern of a water heater? Or a thermostat?
What’s an equation for how methane emissions would vary with meat consumption?
If a given country were to reduce deforestation by a given amount, how would that affect how much carbon it sinks?
How do you quantify “eating wisely” and “trimming your waste”? And how do you calculate the effects as those quantities change?
People have figured out these things! The formulas exist in Excel spreadsheets and Matlab code, buried on old hard drives somewhere. Sometimes they’re vaguely described in prose in published papers.

I'm not usually bothered by this kind of thing. Media love to bemoan surveys showing lack of basic scientific knowledge among the general population. That kind of thing doesn't alarm me. We're a society in which most people specialize, and it's not surprising if most of us are ignorant in major areas; collectively we can still do pretty well.

[2017-05-15] x [[exercise]] [[creatine]]§

When you lift weights, your muscles are using anaerobic glycolysis to convert glucose available in the muscles to ATP.
Anaerobic glycolysis produces hydrogen ions, which inhibit the enzymes used in anaerobic glycolysis. This inhibition results in you running out of energy at the end of your set.
These ions quickly dissipate as you rest between sets, allowing you to start your next set with almost as much strength as the first.
Eventually though (say, after your 3rd set), you reach a point where you have depleted all the glucose stored in the muscle, and you need to allow a longer rest period to replenish the muscle glucose with glucose from the blood stream.
This is why you suddenly reach a point where you can't do any more sets - there's no fuel left in your muscles for glycolysis.
  • This is precisely why creatine "works". Creatine turns into creatine phosphate, which reacts with ADP to form more ATP. It won’t make you stronger by itself, but it will allow you to train harder by providing you with "free" ATP.
  • By providing extra ATP, it enables you to perform more reps and therefore tolerate more stress before you fatigue. The more stress you induce, the more your body has to adapt. I think the mechanism I outlined is what the general consensus is. There are some people who dismiss creatine as "woo" and claim its sole effect is to induce water retention. These people are clueless. Creatine is the single best-attested and best-validated workout supplement other than protein powder. It has diminishing returns, however; furthermore, it is found naturally in food, and excessive intake leads to bloating. These factors cause some people to avoid it.

Bear in mind that the scientists in the Manhattan Project thought they were developing a weapon to destroy Hitler. (As it happened the war in Europe ended a few months before the bomb was ready.)
When you consider that von Neumann was Jewish, and had worked in Germany just before Hitler's rise to power, and certainly had many, many friends and colleagues lose their lives in the death camps--it starts to make a bit of sense. With historical figures like this, I often find it helpful to imagine being in their shoes making decisions, rather than thinking about it from our detached current-day perspective with perfect hindsight.
Also you've probably learned that von Neumann invented the modern subject of game theory. He understood that Mutual Assured Destruction meant that, ironically, the great powers would be unlikely to ever use nuclear weapons against each other. Which has--so far--been the case. Von Neumann, if he were alive today, might point out that the number of people killed in wars has dramatically dropped since the invention of the bomb.

Only the first three Lagrangian points are unstable positions. They're unstable in the same way as the point at the top of a hill. A ball balanced exactly in the center of the peak will stay put, but given a slight nudge in any direction it will roll down the slope and away.
(This is the main reason SOHO doesn't sit exactly on the L1 point, but orbits it instead.)
The Trojan points, L4 and L5, are stable. They act more like the bottom of a bowl. If an object there is nudged, gravity will tend to draw it back toward where it started.

[2014-01-27] Is there any truth to the story of Heisenberg intentionally sabotaging the Nazi nuclear program in WWII? /r/AskHistorians§

During World War II, the German atomic energy program decided, by 1942, to be entirely focused on reactor development. This was, they thought, the area of nuclear fission research was most likely to produce useful military results in the short term. They thought bombs were probably possible but incredibly difficult to construct, and did not think any other nation was going to have any success with them in the short term. The German teams honestly thought they were ahead of the entire world in fission research, and when a group of the top people were carted off to a British manor house, Farm Hall, at the end of the war, they thought that maybe the Allies were trying to keep them from giving their knowledge to the Soviets (true) and that the Allies would want their knowledge for themselves (false).

When they heard about the bombing of Hiroshima, they were shocked and surprised. Many of them refused to believe the United States could have pulled off a bomb. After getting more news information and talking it over, they realized it was in fact possible if the USA had thrown tremendous resources at it, and also realized that some of their assumptions about the size of the critical mass for the bomb were off.

This left them in a tricky situation in terms of their egos and their nationalism. Were they simply failures? This is what Otto Hahn (discoverer of fission, and no fan of Hitler) suggested — that they were just second-raters.

But many of them started to create and cling to a different story. They weren't accidental failures — maybe they were _deliberate_ failures. Maybe they didn't really _want_ to make a bomb, and that's why they didn't do it. This isn't the same thing as saying they _intentionally sabotaged_ the project, but it was more of a psychological explanation. If they had wanted to make a bomb, surely they would have done more work in that direction, right? So they must not have wanted to make a bomb. Because who would want to give Hitler a bomb?

This story — known to historians as the _Lesart_ of the German atomic program — was propagated in subtle ways in the aftermath of World War II. It achieved its initial circulation in Robert Jungk's _ Brighter than a Thousand Suns_ (_Heller als tausend Sonnen_) in 1956. Jungk was the first to suggest, based on a vague _Lesart_ explanation offered up by Heisenberg, that Heisenberg had intentionally sabotaged the project. Heisenberg himself was somewhat appalled by this. Here is what he wrote to Jungk in 1956:

> You speak here towards the end of the second paragraph about active resistance to Hitler, and I believe—pardon my frankness—that this passage is determined by a total misunderstanding of a totalitarian dictatorship. In a dictatorship active resistance can only be practiced by people who seemingly take part in the system. When someone speaks openly against the system, he quite certainly deprives himself of any possibility of active resistance. For either he then expresses his criticism of the system only occasionally in a politically harmless form, and then his political influence can be blocked very easily; say, with respect to the youth, by people saying: Sure, old Professor X is a nice old man, but he naturally has no understanding for the enthusiasm of the youth, or something of the sort. Or, conversely, he really tries, say, to move the students politically, and then within a few days he naturally would meet his end in a concentration camp, and even his self-sacrificing death would remain practically unknown, since no one would be allowed to talk about it. _I would not want this remark to be misunderstood as saying that I myself engaged in resistance to Hitler._

Which is rather equivocating to say the least. Heisenberg isn't actually implying he did _anything_ in this particular letter, though he is implying that he did some kind of passive resistance.

Historians have gone over Heisenberg's wartime activities in detail. There's no evidence whatsoever of intentional sabotage. Heisenberg actually went to great lengths to show he was in line with Nazi Germany's overall foreign intentions, and used his position to stump for Germany and German culture in occupied countries. He vigorously pursued reactor research. He did not vigorously pursue bomb research, but this is because, again, he did not think it was feasible in the short term. Here is another Heisenberg letter to Jungk, from 1957:

> [In 1941] we in the uranium project had come to the following conclusion, on the basis of our experiments with uranium and heavy water: It will definitely be possible to build an energy-producing reactor out of uranium and heavy water. In this reactor (on the basis of theoretical work by von Weizsäcker) a product of U-239 [U-239 decays into Plutonium-239] will be generated that, like U-235, will be suitable as an explosive for atomic bombs. At the time we did not know of any process that could have produced significant quantities of U-235 with an effort that could be realized technically in Germany under wartime conditions. Since the production of atomic explosives using reactors could also obviously be realized only through many years of running huge reactors, it was clear to us in any case that the production of atomic bombs would only be possible with an enormous technical effort. Thus we knew that atomic bombs could be made in principle, but we also estimated that the necessary technical effort was
bigger than it really was.

> This situation seemed to us a particularly favorable precondition for the physicists to have an influence on the further course of events. For if the production of atomic bombs had been impossible, then the problem would not have arisen at all; but if it had been easily possible, then the physicists surely would not have been able to hinder their production. But the actual situation gave the physicists at this time a decisive influence on the further course of events, since they could argue vis-a-vis their governments that the atomic bombs would probably not come into
play in the course of the war, or else argue that it would instead perhaps still be possible, with absolutely enormous efforts, to put them into play. That both ways of arguing were objectively fully justified was shown by the course of developments; for in fact even the Americans could not put the atomic bomb to use against Germany.

The first paragraph of this letter is born out through documentation — the Germans knew that reactors might be a route to the bomb, but they also knew it would require large reactors. Their work on a small research reactor (which would have been worthless for bomb use) was slow and piecemeal and did not reflect any active bomb concern. They knew about uranium enrichment but considered it too difficult to really pursue in earnest.

The second paragraph is the more problematic one. Again, Heisenberg isn't actually saying that he sabotaged anything. What he's saying was, under the conditions that existed, physicists could have pushed for the bomb if they really thought they could do it, but nobody in the government would fault them if they didn't. Is he saying they didn't push for the bomb because they didn't want Hitler to have one? No. But he's allowing that interpretation to be made if you want to make it.

In short, even Heisenberg himself didn't ever really claim that he sabotaged the German atomic bomb project in any real way. At best he implied that maybe he wasn't as enthusiastic about the bomb as he could have been, which is in line with the preservation of the idea that he wasn't just a screw-up on this front. But there's no evidence he did anything like that. Of course, as Heisenberg himself pointed out in the first letter I quoted, the nature of being a passive resister in a totalitarian government is that you appear to be going along with the plan but you might not actually be going along with it. This makes the Heisenberg issue a tricky one for historians, because, as he points out, if he simply withheld enthusiasm for the bomb but otherwise made like a good German, it would be _indistinguishable_ from the situation where he just didn't push for it because he thought it wasn't very feasible.

I think the Farm Hall transcripts make it clear that Heisenberg truly didn't think it was feasible, and in fact hadn't thought seriously about the physics of atomic bombs at all. (His discussions there reflect deep misunderstandings about how fast neutron fission chain reactions work.) Which to me puts him in the "was just a screw-up" camp, as opposed to the "was silently and passively resisting" camp.

[2018-09-04] How did people deal with rotting teeth before modern dentistry and antibiotics? /r/AskHistorians§

Mostly they just suffered through. In some cases they had teeth pulled. In general, prior to modern highly starchy highly sugary diets people didn't have quite so many teeth problems, though even so any dental problems that remain without remedy tend to be extremely painful and life altering.
There are many historical stories of people laboring through tooth and mouth pain. The oldest historical accounts of tooth problems are seven millenia old from Sumeria. Historically there was a misconception that cavities and tooth decay were caused by a "tooth worm", which is a surprisingly common belief across many different separate cultures. This might be due to the appearance of the tooth nerve, which is somewhat worm-like.
As an example, Queen Elizabeth I of England had a history of bad teeth, and suffered from toothaches from time to time. In one case she had such a severe toothache that she couldn't sleep or get much done and eventually had the tooth extracted.
Historical records are not really good enough to get reliable statistics on dental issues as a cause of death, though there have been studies on remains to estimate such statistics (such as [this one](http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3094918/)) which generally come to the conclusion that poor dental health contributed to higher mortality.

Animals used in scientific research in 1 year = animals eaten by humans in 1 day = animals killed by cats in 2 w.e.
Scientists use animals with care and parsimony, and only when no alternative is available. We still cannot move forward without them, there is too much at stake.

[2017-11-30] protein folding [[complexity]]§

given a chain of amino acids, can you predict how is it going to fold?
ideally, folding should end up in the minimal energy state. if it doesn’t you end up with prions?
in general, folding is an NP complete problem, are our body cells actually solving them somehow?
conjecture: evolution wouldn’t actually use hard instances of protein folding, only computationally easy ones.

[2017-05-15] Fermentation§

yeast anaerobic -> alcohol
muscle anaerobic -> lactic acid 

Fermentation is a metabolic process that converts sugar to acids, gases, and/or alcohol.
Fermentation takes place in the lack of oxygen (when the electron transport chain is unusable) and becomes the cell’s primary means of ATP (energy) production.[1] It turns NADHand pyruvate produced in the glycolysis step into NAD+ and various small molecules depending on the type of fermentation (see examples below). In the presence of O2, NADH and pyruvate are used to generate ATP in respiration. This is called oxidative phosphorylation, and it generates much more ATP than glycolysis alone. For that reason, cells generally benefit from avoiding fermentation when oxygen is available. Exceptions include obligate anaerobes, which cannot tolerate oxygen.

[2019-08-25] How are molecular structures determined with such precision? How were they determined in the past? /r/askscience§

My question was inspired by learning that [lutein](https://en.wikipedia.org/wiki/Lutein#/media/File:Lutein_molecule_spacefill.png) and [zeaxanthin](https://en.wikipedia.org/wiki/Zeaxanthin#/media/File:Zeaxanthin_molecule_spacefill.png) are nearly identical molecules (C40H56O2), with the only difference between the two being that a single double bond is found in neighboring positions along a hexagon at one end of the molecule. These molecules are rather large. How are molecular structures determined so exactly? When did chemists acquire this capability? And what were the major milestones in our ability to determine molecular structure?

I don't just mean how many of each kind of element and where they are, but also things as subtle as the position of a single double bond. A lot of molecules are smaller than a wavelength of visible light, so it's not as if we could just look at them under a microscope, yet we know their structures exactly. So how do chemists figure these things out?

[2020-04-05] How does “even if this flu shot isn’t an exact match, if you do get the flu it won’t be as bad” work? /r/askscience [[vaccine]]§

There's actually a very cool effect where either getting infected with flu or getting vaccinated boosts your antibody response to all previous strains of flu you've encountered (by getting flu or by being vaccinated). In recent years WHO have begun to shift towards using antigenically advanced vaccines, whereby they predict how currently circulating strains of flu will evolve and artificially create vaccines for the flu strain they think will be circulating in 6 months time, as even if the virus doesn't mutate to a new strain, the antibody backboost means you still get protection against most circulating strains. Check out this paper (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4246172/) if you want a more detailed explanation, but basically the vaccine can boost your antibody response to a fairly wide range of influenza virus strains  (this is at least true for type A H3N2 influenza, there are 4 different types of influenza in the annual vaccine)

[2018-07-06] White chocolate is only cocoa butter + sugar + cream§

[2018-05-29] Oil: one reason for using oil is just to make a thermal path between the pan and the food, so the food doesn’t only cook exactly where it touches.§

The reason boiling doesn't achieve browning, is that water cannot be heated above 100C, except at extreme pressures. The Maillard Reaction is commonly what turns food brown and produces a pleasant taste, and this happens at 140 to 160 C.
And according to: http://www.finecooking.com/article/the-science-of-frying
"When food is plunged into hot oil, the water in the food starts to boil and percolate toward the surface. In order for a crisp, dry crust to develop, there must be a barrier between the hot oil and the migrating water. This barrier is typically something starchy. As the starch fries in the hot oil, it dries into a pleasantly crisp shell and protects the moisture beneath. The food inside steams while the coating browns and crisps."
EDIT: As /u/Choralone points out below, the Maillard reaction can take place at lower temperatures, but very slowly. So cooking items over several hours can sometimes produce similar results, but perhaps not with the types of food that are normally fried.

Debunk This: This is The Most Powerful Natural Antibiotic Ever – Kills Any Infections in The Body https://www.reddit.com/r/DebunkThis/comments/2sfk0g/debunk_this_this_is_the_most_powerful_natural/§

Garlic:
It does contain an antibiotic compound known as allicin. The wiki article does a good job summing it up: allicin comes from bruised garlic tissue (but not from consumed garlic in the body). You can see the inhibitory concentrations in the article run as low at 16 mg/L in water. To reach those levels in the human body, you'd need roughly 5.5 times as much: ~88 mg in your circulating blood. Since there's roughly 9 mg allicin per garlic clove, this recipe would need roughly 10 cloves of garlic per dose. However, this same study did find an interesting use for purified allicin at level far above what you find in garlic.

Hot peppers
Without an exact species of pepper, we can just assume the ingredient of interest here is the spice itself: capsaicin. Medical uses of capsaicin are primarily in pain treatment, not in fighting infections. I have found no evidence that consuming capsaicin is antibiotic.

between amino acids and reducing (TODO?) sugar

about 220 degrees (TODO fahrenheit?) is necessary to trigger it

some Maillard reaction results enhance other flavors

Example:

Melting of sugar
TODO onions?? browning and umami taste

TODO exothermal, so easy to overcook

Temperatures need to be high to bring about the Maillard reaction, but as long as the food is very wet, its temperature won’t climb above the boiling point of water. At atmospheric pressure, only high-heat cooking techniques can dry out the food enough to raise the temperature sufficiently. It’s not the water that stops the reaction, but rather the low boiling point at normal, sea-level pressure. In the sealed environment of a pressure cooker, the Maillard reaction can,— and does—, occur.

Drying and browning the surface first will, however, allow the reaction to proceed slowly at temperatures below the boiling point of water.

https://www.reddit.com/r/askscience/comments/946wd9/is_mold_in_blue_cheeses_different_in_any_way_from/e3j8s6n/ 

 Grey mould, the soft hairy mould you see growing on fruit you leave out too long, is Botrytis cinerea. It is one of the world's most common agri/horticultural pests, in everything from floristry to tomato farming.
It is also a vital ingredient in a certain type of dessert wine. If grapes on the vine are infected with Botrytis and then kept below a certain temp and relatively dry, the mould infection is called Noble Rot. The grapes do not rot, they become permeable and allow water to evaporate, thus concentrating the sugars.
I find it interesting to note that the same pest that ruins your tomato plants is, in another scenario, a necessary ingredient in high quality wine products.

Alternatively one can think of Riemann sheets whereby on crossing a branch cut
one moves onto a different Riemann sheet of the function; the number of branches equals
the number of Riemann sheets. This allows closed contours to be formed by going around
branch cuts as many times as required to get back to the original Riemann sheet. However
although this scheme is very elegant, for calculational purposes it is best to treat branch

This is why they show up as steady-state solutions to the heat equation: if this averaging property weren’t true, then heat would be flowing either from or to a point.

In mathematics, the tensor product V ⊗ W of two vector spaces V and W (over the same field) is itself a vector space, together with an operation of bilinear composition, denoted by ⊗, from ordered pairs in the Cartesian product V × W into V ⊗ W, in a way that generalizes the outer product. The tensor product of V and W is the vector space generated by the symbols v ⊗ w, with v ∈ V and w ∈ W, in which the relations of bilinearity are imposed for the product operation ⊗, and no other relations are assumed to hold.

[2016-06-20] continuity intuition [[topology]]§

Consider the statement "a continuous function preserves closeness". That means if f ( x ) f(x) and f ( y ) f(y) are close to each other then x x and y y were close to each other originally.

In analysis, a function is continuous if you can make the image in the codomain as small as you like, by choosing a small enough part of the domain.

https://math.stackexchange.com/questions/15963/what-is-the-intuition-for-the-point-set-topology-definition-of-continuity§

Instead, in metric spaces, I think of a function as continuous if it preserves limits, which can be intuitively (and generalizably) be phrased by saying that f is continuous if and only if whenever x is in the closure of a set A, then f(x) is in the closure of the set f(A).

why the reverse doesn’t work?§

topology as set of rulers https://mathoverflow.net/a/19156§

This analogy is a backport from computer science back to geometry, and a bit was lost in the translation. In CS, for open, read "verifiable", and for closed, read "non-verifiable". Termination of blackbox programs is a verifiable property: if someone gives you a program and tells you it halts, then if they’re telling the truth, if you wait you’ll eventually see the machine stop and know they told you the truth. Nontermination is non-verifiable: no matter how long we wait, we can never be sure that the program won’t halt soon, and so we can’t verify we were told the truth. –

mm. ok, function is continuous at p iff p in cl(A) means f(p) in cl(f(A)). okay that does make way more sense

hmm interesting definition in terms of ‘touches’ (v)

in terms of closeness https://mathoverflow.net/a/19173/29889§

  • No point touches the empty subset.
  • If x is an element of A, then x touches A.
  • If x touches A∪B, then x touches A or x touches B.
  • If x touches A, and every element of A touches B, then x touches B.

then,

  • continuity at point: forall A. x v A => f(x) v f(A)
    e.g. f(x) = sign(x). If we take x = 0 and A = (0, 1). In usual topology, 0 touches A, so f(0) = 0 should touch {1}. But it doesn’t!
  • X is connected iff every continuous function from x to {0, 1} is constant
    e.g. take two sets A, B. if you define f(A) = 0 and f(B) = 1 that’s ok since B has no points near A and vice versa
    from nearness a better approach to continuity
  • disconnected: if A∪B = X, A not v B and B not v A
  • The sequence (xn) converges to the point x if x touches every subsequence of (xn).
  • The topological space X is Hausdorff if for any two distinct points w,x∈X, there is a subset A of X such that w doesn’t touch A and x doesn’t touch the complement of A.
    dunno, this one is weird
    TODO shit, I really want the ability to insert todos wherever I want, not only on outline levels

compactness??§

open set: if no point touches its complement? e.g. with (0, 1) for any specific point we will find interval that separates from [-inf, 0] U [1, inf]§

and in reverse: x touches X if for all O in tau contaning x, U intersect X is not empty. ah shit makes sense.

if there is a continuous map to Sierpinski space?
sierpinski space: topologically, {}, {top}, {top, bot}. so, bot v {top} but not in reverse
this is also simplest example for non-symmetry I guess
ugh. this is crap.
https://math.stackexchange.com/questions/31859/what-concept-does-an-open-set-axiomatise
Note that the above description really brings out the special role of the Sierpinski space S. Indeed, a subset of a topological space X is open precisely when the indicator function X→S is continuous.

[2019-01-26] right, I spent more than an hour proving something that could not be proved.. (that 0 touches (0, 1)). It really doesn’t e.g. in discrete topology§

frequentist vs vs bayes probability§

https://stats.stackexchange.com/questions/31867/bayesian-vs-frequentist-interpretations-of-probability 

The snag is that we have to introduce the prior distribution into our analysis - this reflects our belief about the value of p before seeing the actual values of the Xi. The role of the prior is often criticised in the frequentist approach, as it is argued that it introduces subjectivity into the otherwise austere and object world of probability.
It might also be good to mention that the gap between the frequentist and Bayesian approaches is not nearly as great on a practical level: any frequentist method that produces useful and self-consistent results can generally be given a Bayesian interpretation, and vice versa. In particular, recasting a frequentist calculation in Bayesian terms typically yields a rule for calculating the posterior given some specific prior. One can then ask "Well, is that prior actually a reasonable one to assume?"
You're right about your interpretation of Frequentist probability: randomness in this setup is merely due to incomplete sampling. From the Bayesian viewpoint probabilities are "subjective", in that they reflect an agent's uncertainty about the world. It's not quite right to say that the parameters of the distributions "change". Since we don't have complete information about the parameters, our uncertainty about them changes as we gather more information.
A Bayesian may say that the probability that there was life on Mars a billion years ago is 1/2.
A frequentist will refuse to assign a probability to that proposition. It is not something that could be said to be true in half of all cases, so one cannot assign probability 1/2.
Frequentists posit that the probability of an event is its relative frequency over time,[1] (3.4) i.e., its relative frequency of occurrence after repeating a process a large number of times under similar conditions. This is also known as aleatory probability. The events are assumed to be governed by some random physical phenomena, which are either phenomena that are predictable, in principle, with sufficient information (see determinism); or phenomena which are essentially unpredictable. Examples of the first kind include tossing dice or spinning a roulette wheel; an example of the second kind is radioactive decay. In the case of tossing a fair coin, frequentists say that the probability of getting a heads is 1/2, not because there are two equally likely outcomes but because repeated series of large numbers of trials demonstrate that the empirical frequency converges to the limit 1/2 as the number of trials goes to infinity.

https://www.reddit.com/r/statistics/comments/ywrba/eli5_bayesian_statistics/ 

Bayesian statistics rely more on computational simulations and have become more common because computers have become much faster. A lot of people are put off by the fact that you incorporate prior believes into your estimate of the "truth", but you can use non-informative (vague) priors like in the example above (each possible outcome gets equal probability) and in any case with a lot of data your priors will become less important.

so the idea is that some systems behave as a function of their components (and each component is a function of its subcomponents etc)
(sort of like dynamic programming?)

the coupling can express interaction between particles, e.g. for a magnetic system it can express tendency of neighbouring particles to oppose their spins
if we have parameters, describing the system, we can iterate the process (going from smaller to larger subproblems)?
sometimes we’ll run into ‘fixed points’ (of coupling/macro parameters?), which correspond to phase transitions

[2020-07-20] Spin isomers of hydrogen - Wikipedia§

Molecular hydrogen occurs in two isomeric forms, one with its two proton nuclear spins aligned parallel (orthohydrogen), the other with its two proton spins aligned antiparallel (parahydrogen).[1] These two forms are often referred to as spin isomers.[2]

Parahydrogen is in a lower energy state than is orthohydrogen. At room temperature and thermal equilibrium, thermal excitation causes hydrogen to consist of approximately 75% orthohydrogen and 25% parahydrogen. When hydrogen is liquified at low temperature, there is a slow spontaneous transition to a predominantly para ratio, with the released energy having implications for storage. Essentially pure parahydrogen form can be obtained at very low temperatures, but it is not possible to obtain a sample containing more than 75% orthohydrogen by heating.

[2020-07-20] Hydrogen Molecule§

The potential energy of the anti-bonding orbital shown gives some insight into why a third hydrogen atom cannot bond to the two atoms of the hydrogen molecule. It would be in an anti-bonding situation with one of the other hydrogen atoms and would therefore be repelled. We say that the bond in the hydrogen molecule is "saturated" because it cannot accept another bond.

[2020-07-20] Exchange interaction - Wikipedia§

Both bosons and fermions can experience the exchange interaction. For fermions, this interaction is sometimes called Pauli repulsion and is related to the Pauli exclusion principle. For bosons, the exchange interaction takes the form of an effective attraction that causes identical particles to be found closer together, as in Bose–Einstein condensation.

[2020-07-20] D.23 Solution of the hydrogen molecule§

The nucleus to electron attraction energies are 82 eV for the symmetric state, and 83.2 eV for the antisymmetric state, so the antisymmetric state has the lower potential energy, like in the hydrogen molecular ion case, and unlike what you read in some books. The symmetric state has the lower energy because of lower kinetic energy, not potential energy.
Due to electron cloud merging, for the symmetric state the electron to electron repulsion energy is 3 eV lower than you would get if the electrons were point charges located at the nuclei. For the antisymmetric state, it is 5.8 eV lower.
As a consequence, the antisymmetric state also has less potential energy with respect to these repulsions. Adding it all together, the symmetric state has quite a lot less kinetic energy than the antisymmetric one.

[2020-07-20] Molecules§

When two hydrogen atoms approach each other, the final configuration depends on the spin of the two electrons (a consequence of the Exclusion Principle). If the spin of the two electrons is parallel as shown in the right side of Figure 12-08, the two atoms remain separated. However, if the spin of the two electrons is antiparallel as shown in the left side of Figure 12-08, the two atoms combine to form a hydrogen molecule. There is a high probability of finding the electrons in between the atomic nuclei and this "electron cloud" tends to keep them from breaking up. This kind of binding is called covalent bond, and is purely

[2020-07-20] I am very confused about anti-bonding orbitals, how they form? I mean when two atomic orbitals produce bonding orbital + anti-banding orbital?? Please clear my basics. I am really worried, please solve my problem | Socratic§

[2020-07-20] I am very confused about anti-bonding orbitals, how they form? I mean when two atomic orbitals produce bonding orbital + anti-banding orbital?? Please clear my basics. I am really worried, please solve my problem | Socratic§

Half of the molecular orbitals obtained by combining atomic orbitals of the same or similar energy are more stabilized (have less energy) than these and we will call them bonding. The other half are called anti-bonding and have more energy than the atomic orbitals from which they come. They are usually represented by adding an asterisk (*) to the name of the orbital.

[2020-07-20] Chapter 9, Section 7§

In contrast, the hypothetical He2 molecule requires four electrons to fill its molecular orbitals, as in Figure 9.33(b). Because only two electrons can be put in the 1s orbital, the other two must be placed in the *1s. The energy decrease from the two electrons in the bonding molecular orbital is offset by the energy increase from the two electrons in the antibonding orbital. (In fact, antibonding molecular orbitals are slightly more unfavorable than bonding orbitals are favorable. Thus, whenever there is an equal number of electrons in bonding and antibonding orbitals, the energy is slightly higher than it is for the isolated atoms and no bond is formed.) Hence, He2 is not a stable molecule. Molecular orbital theory correctly predicts that hydrogen forms diatomic molecules but helium does not.

In quantum chemistry and molecular physics, the Born–Oppenheimer (BO) approximation is the most known mathematical approximation in molecular dynamics. Specifically, it is the assumption that the motion of atomic nuclei and electrons in a molecule can be treated separately, based on the fact that the nuclei are much heavier than the electrons.

[2020-07-20] The Feynman Lectures on Physics Vol. III Ch. 10: Other Two-State Systems§

For instance, “electron a” might be near the first proton and “electron b” might be in another state around the same proton. We’ll disregard such a case, since it will certainly have higher energy (because of the large Coulomb repulsion between the two electrons). For greater accuracy, we would have to include such states, but we can get the essentials of the molecular binding by considering just the two states of Fig. 10–4. To this approximation we can describe any state by giving the amplitude ⟨1|ϕ⟩ to be in the state |1⟩ and an amplitude ⟨2|ϕ⟩ to be in state |2⟩. In other words, the state vector |ϕ⟩ can be written as the linear combination
|ϕ⟩=∑i|i⟩⟨i|ϕ⟩.

[2020-07-20] The Feynman Lectures on Physics Vol. III Ch. 10: Other Two-State Systems§

which is −|I⟩, as required. So if we bring two hydrogen atoms near to each other with their electrons spinning in the same direction, they can go into the state |I⟩ and not state |II⟩. But notice that state |I⟩ is the upper energy state. Its curve of energy versus separation has no minimum. The two hydrogens will always repel and will not form a molecule. So we conclude that the hydrogen molecule cannot exist with parallel electron spins. And that is right.

[2019-02-13] The Frustrating Success of Our Best Theory of Physics /r/Physics§

Noether's first theorem applies to global symmetries (finite groups, to be more precise) and leads to charges which are conserved upon imposing the equations of motion, aka the laws of physics (meaning it's not mathematically inconsistent to imagine charges not being conserved, it's just that real universes don't have that).

Noether's second theorem applies to local symmetries (infinite groups) and leads to redundancies between the equations of motion called Bianchi identities. These identities must be satisfied always, period. It's mathematically inconsistent for them to be violated.

@patrickc 4/4 So the derivation you speak about is just running this history in reverse, showing that magnetism is just a relativistic aspect of electricity.
Purcell did it in the 60s, and Hans de Vries updated this in 2008, with a much simpler derivation.

I do not buy his shtick because Richard Feynmann (who has ACTUAL contributions in physics) does a way better job in explaining  concepts. I agree with Einstein when he says "If you can't explain it simply, you don't understand it well enough", and since Eric talks in such a convoluted manner about his theory (even in his lecture), it seems to me that Eric's goal is NOT to present his idea.. but to plant this idea in his audience that he is right and the entire academic community is corrupt and wrong.

I actually share that sentiment and I agree that academia has its fair share of issues (self citation, institutional bias etc).. But if you do not even upload a manuscript on the internet and expect your audience to believe your claims purely based on your vague explanation of your theory.. I just do not trust him.

Avogadro's law holds because a perfectly ideal gas behaves exactly like a huge number of rigid macroscopic particles flying around and colliding (billiard balls, air hockey pucks, etc.).
For a given temperature, pressure, and volume, the only other quantity of interest is the number of particles.
Their masses do not matter because this is already taken into account in the temperature (average kinetic energy), so all systems of "ideal gasses" (or billiard balls) with the same P, V, T and particle number behave in the same way.

[2015-03-16] How fast does electricity move in a wire? /r/askscience§

~~Electronics~~ Electrons (thanks /u/StopDataAbuse) push each other away because of their negativity. This is what transfers the signal, and goes at about 50% to 99% of the speed of light depending on the material. Note that this is not related to the actual speed of the electrons themselves.
Now the speed of the electrons themselves is more interesting (I think). I once calculated this and I'll do it again for fun. Let's take a simple DC circuit:
3 volt power source, 3 ohm resistor giving 1A of current. Lets take 18 awg copper wires with a cross section surface of 0.823mm^2 according to [this](http://www.technick.net/public/code/cp_dpage.php?aiocp_dp=guide_awg_to_metric). The length of the wires we'll define as L meter, as you'll see it doesn't matter which L we pick as long as we ignore the resistance it brings.
The volume of the wire is 0.823mm^2 * L meter = 0.823 10^-6 * L m^3. The density of the wire is (from Wikipedia) 8.96 g * cm^-3  = 8960 kg * m^-3. Multiply those numbers and we'll get the weight of the wire, which is 7.374 * L * 10^-3 kg. I searched for the number of free electrons every copper atom has, and a google search returns 1. So now we need the number of atoms in those wires. 7.347 * L g / (63.546 g / mol) * 6.022 * 10^23 / mol = 6.988 * 10^22 L. That's the number of free electrons in the wires. 1A is 1C / s = 6.241 * 10^18 electrons per second. That's the number of electrons that flow into the wire and out the other end every second. Divide 6.988 * 10^22 L with 6.241 * 10^18 / s and you'll get 11197 * L s. That's the number of seconds any electron stays in the wires before leaving the other end. Divide the length by this time and you'll get the speed: speed = L meters (as the length of the wires were L) / (11197Ls) = 8.93 × 10^-5 m / s. That's not very fast. It would take over 3 hours to travel through a 1 meter wire. Hope I got all the numbers right :S

Variance [[plt]]§

The question: what are the conditions for the function A -> B to be a subtype of C -> D?

1. A is subtype of B means there is a special function castAB :: A -> B
2. Two casts compose into another casts, cast compositions are isomorphic (that is, castBC . castAB is essentially the same thing as castAC)
3. We wanna implement castAfB -> castCfD in order to show (A -> B) <: (C -> D)

  - X :: (A -> B) -> (C -> D)
  - we can only use functions applications and cast
  - X (fab :: A -> B) (c :: C) = ? :: D
  - the only thing we can do is to transform c to some another type, that is, we need castCT :: C -> T
  - now, we have (castCT c) :: T, basically, leaves us in the same situation, so, we actually need castCA :: C -> A
  - now, we have (castCA c) :: A, and (fab $ castCA c) :: B. The only way to get D is to use castBD :: B -> D

5. So, we have (A -> B) <: (C -> D), that is, A -> B is subtype of C -> D if C is subtype of A and B is subtype of D.


The return type (B and D) is covariant, since preserves the direction of <:
The argument type (A and C) is contravariant, since it flips the direction of <:


Container reading: covariant:

: S <: T, then ReadonlyCollection<S> <: ReadonlyCollection<T>

Container writing: contravariant:

: S <: T, then Consumer<T> <: Consumer<S>

- C++ poiners: covariant
- Java
  - arrays: covariant
  - Collection<? extends T>: covariant
  - Collection<? super T>: contravariant

[2019-08-11] dariusk/corpora: A collection of small corpuses of interesting data for the creation of bots and similar stuff.§

https://github.com/dariusk/corpora 

This project is a collection of static corpora (plural of "corpus") that are potentially useful in the creation of weird internet stuff. I've found that, as a creator, sometimes I am making something that needs access to a lot of adjectives, but not necessarily every adjective in the English language. So for the last year I've been copy/pasting an adjs.json file from project to project. This is kind of awful, so I'm hoping that this project will at least help me keep everything in one place.

Nullable strings Vs unset column in databade [[db]]§

Most of this advice is stuff they tell you in school that doesn’t matter at all in reality.
Real advice:
- Normalize until it hurts, denormalize until it works. (I.e. prefer normal forms but denormal will have better performance.)
- You need nullable dates and nullable numbers. You never need a nullable string. If you must distinguish blank string from unset, add a column called “unset”. Using null for this will just result in bad data entry.
- Names should be stored as display_name, first_name, and last_name. A display name is not the same as just first plus last. They have different purposes, so don’t shove them together.
- When in doubt, just have a column full of JSON and figure it out later.
- Offset pagination is bad for performance. Avoid it at all costs unless you want some spider indexing page 10,432 of your archives to eat all your CPU.

[2018-08-27] A Road to Common Lisp / Steve Losh /r/lisp§

I've always liked this example, from _Practical Common Lisp_ (2007).
> `DOLIST` is similar to Perl's `foreach` or Python's `for`. Java added a similar kind of loop construct with the "enhanced" `for` loop in Java 1.5, as part of JSR-201. Notice what a difference macros make. A Lisp programmer who notices a common pattern in their code can write a macro to give themselves a source-level abstraction of that pattern. A Java programmer who notices the same pattern has to convince Sun that this particular abstraction is worth adding to the language. Then Sun has to publish a JSR and convene an industry-wide "expert group" to hash everything out. That process--according to Sun--takes an average of 18 months. After that, the compiler writers all have to go upgrade their compilers to support the new feature. And even once the Java programmer's favorite compiler supports the new version of Java, they probably still can't use the new feature until they're allowed to break source compatibility with older versions of Java. So an annoyance that Common Lisp programmers can resolve for themselves within five minutes plagues Java programmers for years.

We don't need new languages without features: it has already been proven that you only need exactly one feature in your programming language to write any program possible. Look up single instruction languages for proof that it is possible and such single features languages exist.
What we need are languages with many features that are easy to use to create complex programs that are still easy to understand.

awk
This was a tool written by three of the smartest people in the field at the time (Aho, Weinberger, Kernighan) to solve a problem they had often.
awk is still an excellent tool for exploring unstructured, semi-structured, and record-based data, and can be abused for lots of other use cases. Despite it’s age, it still includes many features that people expect from modern languages (hash tables, not having to pre-declare variables, easy use of regexes). If you know awk, you can throw out a lot of other shell tools, such as grep, cut, head, tail, and many more. Where I might have reached for a dozen or two line Python script, I often just write a dozen or two characters of awk.
“The AWK Programming Language” is one of the clearest and most concise technical books I’ve ever read, and definitely the best ROI I’ve gotten from reading any book.

The solution is to use tabs for indentation but spaces for alignment. So for the second line of your code example, tabs would be used up to the indentation level of int, and spaces would be used from that point on to align float.

“Rolling out one’s own programming language” is a very common fallacy in software development. It struck hard many projects where the configuration or programming language was:

    limited in expressiveness and features;
    yet another language to learn (but not something very useful and reusable) which requires some effort on the user end and thus creates an entry barrier;
    harder to read (at least at the beginning);
    and often with poor performance.

The fundamental difference between Rust's approach and Java-style checked exceptions arises when those three functions have different error types. In Java, you would annotate the function with every possible exception that the function can throw. In Rust, a library (or module with a library) would normally design its own Result type to encompass every error that the library/module can throw, and use that type on every error-producing function (you could reproduce the Java approach by defining a new Result type for each function, but I've never seen anyone bother with that).

[2021-02-16] #🧠-learning [[opensource]]§

Not an Athens developer, but hopefully can give some general advice..
Generally open source projects welcome contributions, especially if the contribution complies with project guidelines, covered with tests, doesn't contain unrelated changes, etc.. However there are some things to consider:

One of the biggest factors is maintainer's time, and often guiding a person to improve their code takes more time & energy than implementing the same from scratch.
I guess for this the only advice is to read guides carefully, search stuff & ask elsewhere if possible, so you would ideally only ask the maintainers for things specific for the project.
Basically whatever you would do in general when you're doing independent learning. Although of course the author might be happy to guide you for small things -- which is great too. But good to keep this in mind.

Another factor to keep in mind is that the developers might want to keep the project compact and minimal in terms of features.
The reason is that generally the more features you have, the more code you have ===> the more likely it would break which is a burden on the maintainer.
Plus depending on the project features that maintainer isn't using themselves would end up poorly tested (yet another reason to make sure you have tests with your contribution if possible).
To avoid this it's best to ask the maintainers whether the feature would be welcome in advance. It's very sad to work on something for a week to find out they don't want to merge it. In some cases you can work off a fork, but not always.

Apart from this, I can't imagine the cases when bugfixes or extra test coverage won't be welcome. Which could also be a great way to get familiar with a new project (or even programming language!).

  • no real notion of immutability
  • no nullable types
  • no generics declaration site variance (producers/consumers)
    • example: immutable Stream<T>, method which returns Stream<R>. If we override it as List in java, there is no way to return List<R>
  • no sum tupes/closed classes (enums are the closest alternative but have no states)
    • if we make interface private, it is hidden from outside
    • alternative: factory methods, enum methods take ‘state’ as argument
  • no type synonims
  • no ‘const’ keyword

> Also, what do you want to use these sorted elements for? It's great if it's just for the sake of it too! But wondering if you're trying to find some cool correlations or something :)

Its a recurring problem in my project ideas where the dataset involves subjective attributes.

For example, one my ideas is creating a software that collects data about your personal day(hours slept, food eaten, medication taken, physical exercise, etc etc) and success metrics(money earned, how productive you are being, fat loss/muscle gain, etc etc) and give the user the correlations between the success metrics and the data describing the days, so the user have a 100% empirical and domain-blind feedback on what works for them. Kinda like what [this](https://medium.com/@mikebechtel/i-tracked-every-single-thing-i-ate-for-a-full-year-here-are-10-quick-a-has-2c259dd2f57b) guy did, but nicely packaged into a single software.

Then theres a lot of attributes that are too subjective(specially some of the success metrics), so having a consistent and methodical way of collecting this data would be useful. Also I have no idea if someone is working on something similar, would love to read some papers/articles about it so I can mature my ideas, see what works and what doesn't.

here was no single formula but one principle that comes up a lot is to change the difficulty of the test dynamically based on the user’s accuracy, to reach a steady state of some fixed accuracy, and apply Bayesian estimation to the parameters of interest. For example, in Digit Span we estimate the level in which the user would get exactly 50% of the trials correct. The reason that our verbal learning test doesn’t use a fixed number of items is that some people would find 10 items too hard and others would find 30 too easy, so any fixed number would waste a lot of their time testing them at an inappropriate level.

In the spirit of own your data, as well as get a bit more visibility for myself on how much I walk and maybe even add some accountability for days I don't walk as much, I thought I'd publish this data to my site.

Hr response depending on power of spinning [[qs]]§

That doesn't take second order effects into account

[2019-10-28] The value of tracking data /r/running (motivation)§

I love data. I love technology.  I love running.  I've got a crap ton of available data on virtually everything having to do with my running/health.  I have a high end Garmin watch, I run with my heart rate strap w/ Garmin Run Dynamics, I have a Stryd power meter, i used to track my HRV every morning, etc.

And it's almost all useless.  The more I've run, the more I've realized how little of it really matters.  Sure you can track your progress any number of ways.  My favorite, RE ratio (basically the amount of running power required for a given pace) very cleanly shows how much my efficiency has improved over long periods of time, but I can also look at long run pace for a given HR, resting HR, implied VO2Max, etc. etc. etc.  Or I could just look at old fashioned race times and see how they compare.

Almost all of this data is descriptive (and sometimes it isn't even meaningful) and it's almost never prescriptive.  The value of descriptive stats is minimal, beyond perhaps for some ongoing motivation to see improvement at regular intervals in the absence of races.  I really think tracking your mileage, pace, perceived exertion, and interval/workout details (when relevant) to be the key factors that are necessary.  It really doesn't take much to collect and track those.

So much of the data collected has false precision (just because a number is being spit out, doesn't mean it has inherent meaning or is accurate), and even more of it is useless without very detailed context.  Heart rate is the best example of this: the temperature, humidity, wind, your fatigue, whether you're sick, what you're wearing, if you had caffeine, if you ate before running, if you had a few beers the day before, etc. will all massively impact your HR on a given run.  Not to mention that people really need to know their max hr, min hr, vo2max hr, and lactate threshold hr for zones to have any meaning... and almost no one knows these numbers.

I have my training plan, and nothing really changes what i'm going to be running on a given day beyond how my body subjectively feels.

[2019-10-28] The value of tracking data /r/running [[motivation]]§

I'm interested in the process of quantified self and gathering information of your body with the help of wearable technology. It'd be interesting to hear from the community, what got you into quantified self and what for you is the value you get from it? What keeps you motivated to gather information or what made you stop?

At the moment I track my running pace and recovery times. I use the information to set a goal for each workout and plan them according to my energy levels. One of my friends is very organized in this sense and has tracked nearly all his runs this year. I've learned a great deal from him but I'd like to know more and understand what other ways there are to make use of the data that's out there.

Binge days weighting poop [[qs]]§

This was a big thing with Tim Ferris when he was making an argument for "cheat days". Personally, I also found cheat days to be effective when on a restrictive diet. I think he ended up actually weighing his poop to prove the point.
I did notice that I couldn't breakthrough some key weight loss levels without both cheat days and intermittent fasting, with the cheat days seeming counter-intuitive to me.

[2020-10-22] analog to digital - comparison between Fourier transform and autocorrelation function - Signal Processing Stack Exchange§

Therefore for random signals, the Fourier transform will not exist and their spectral density cannot be computed that way. Nevertheless, for such signals an indirect description, based on an autocorrelation measure, can also be defined, whose advantage being that the Fourier transform of it may exist. Therefore the PSD of a random process is defined as the Fourier transform of its ACF.

I wouldn't say the autocorrelation is particularly sensitive to noise, but it is sensitive to other frequency components.

Full Article Here:
[https://medium.com/@mikebechtel/i-tracked-every-single-thing-i-ate-for-a-full-year-here-are-10-quick-a-has-2c259dd2f57b?source=friends\_link&sk=ed6113272876d866eeaa23ec05415495](https://medium.com/@mikebechtel/i-tracked-every-single-thing-i-ate-for-a-full-year-here-are-10-quick-a-has-2c259dd2f57b?source=friends_link&sk=ed6113272876d866eeaa23ec05415495)

tl/dr here:

1. Exercise is a Heckuva Anti-Depressant.
2. Sugar & Salt hangovers: Nearly as bad as alcohol hangovers.
3. Two Days of Bad Sleep in a Row Will Mess. You. Up.
4. Weight Loss != Fat Loss
5. Carbs aren't evil. But they're... sneaky.
6. 15% body fat (for a guy) is doable with tasty food. 10% requires you to eat fewer tasty things. 5% requires you to forgo taste (and friends) entirely.
7. Muscles recover strongest 2-3 days after a workout, and stay stronger-than-baseline for about 2-3 days after that. Beyond that, wimpy-ness resumes and you atrophy. (Which is why consistency is key.)
8. Food Scales are your Friend. Casseroles, stews, and buffets are your Enemy.
9. Processed foods are easiest to track (because they have SKU's) but not as good for you. Whole Foods vs. Whole Data.
10. Standard McDonald's Cheeseburgers are, as far as I can tell, the most nutritionally complete food on a macronutrient-per-dollar basis.

 Received my ring last Friday. Had the 1st gen but returned it due to inaccurate sleep readings. Unfortunately, the new ring seems to be inaccurate for me as well. Both rings read that I was asleep when I was meditating, laying awake in bed, or even making coffee. Since the Readiness score is based in part on the Sleep score that’s inaccurate, too. I contacted customer service last night, no word back yet.
The new material of the 2nd gen ring feels cheap and plasticky, although a better size and weight than the 1st gen. Overall, so far, not impressed. Especially after waiting over 9 months. But I look forward to my initial impressions changing for the better with continued use. Would love to hear from other Ōura users as well.

hey, I looked at same thing for tunturi e35. A much cheaper bike. The problem is this not a linear function. In magnetic resistance bikes, torque increases as linear function of RPM.

make the free coefficient positive.

eh, maybe just use "intercept" with a link to wikipedia? not sure if free variable is a common language

If you like hard sci-fi, Greg Egan has a written a few books that cover what life would be like if there were 2 dimensions of time (http://www.gregegan.net/DICHRONAUTS/DICHRONAUTS.html) or if the dimension of time was sumed instead of subtracted when measuring distance (http://www.gregegan.net/ORTHOGONAL/ORTHOGONAL.html)
It's amazing to think how the universe is ruled by such minute details.
