The Selfish Gene is great. The portions on Evolutionary Stable Strategies are particularly interesting. It shows how Darwinism can lead to a "steady state", where a population contains individuals with competing characteristics (s

I don't think Sheldon Axler wants to literally banish determinants, they are a useful tool. But they do obscure the meaning in a lot of proofs. If you start using them immediately, it is also hard to motivate where they come from, what

Might be as a way to differentiate between page views and people reading the article. I think Quora does this. You get a separate counter for people who expand your post.

This does not surprise me much. There have been more than two or three occasions in the past two years where Facebook, Whatsapp and Instagram were having connection issues simultaneously, which for me is an indication of how the services ar

I think you are right, I am complaining mostly about the "front page of the internet" part. I like visiting other subs, and I usually find answers to Google searches there, because some communities are really good.

I am also interested in this... I used to like Reddit a lot, but I feel their push to reach a broader audience has pushed down the quality of the front-page subs. It is dominated by a sense of moral superiority: "Am I the Asshole"

I will read this a bit later, but is the idea to extended the structure of the tangent space and make it a full geometric algebra?

Personally, an appealing part of GA is clarifying that the magnetic field is best viewed as an "oriented area", instead of a pseudo-vector [1], which is a concept that is frequently ill-defined. Usually, lecturers say that the mag

I always see his site mentioned. I am not convinced about this criticism. The author is not an expert on sleep or a neuroscientist. The most you can say is that Walker has not responded to this criticism.

He has a strong opinion that you can only develop perfect pitch while young, and I have to agree. His videos are great.

Yes, that's it.

Indeed! I highly recommend following the author.

Sure, there is certainly a lot of jargon here which I could have explained better, but in the end one has to be familiar with some calculus and complex numbers to make sense of this topic. Depending on where you're from, this could be

I find that the most elegant way to understand exponential-related things is by defining the exponential as the function satisfying f'=f (with suitable normalization). In other words, it is the "eigenfunction" of the derivati

This is part of a monthly series of seminar at the interstection of Quantum Computation and High-Energy Physics. Abstract: This talk has three parts. In part 1, I discuss the current status and near-term prospects for quantum computing and

It's also consistent with the set notation, which makes it easier to remember. Dict keys already kind of work like a set, this extends the behavior to deal with the values as well.

Yes, that's the point. Of course it should be sensible and rounded. If we were too literal with this definition, 12 would even change everyday because of the analemma [1]. [1] https://en.m.wikipedia.org/wiki/Analem

My thoughts exactly. Keep 12pm at the time the sun is in its maximum and just do things earlier/later.

This is a nice summary of the basics of immunology and how it relates to SARS-CoV-2. It's good to see a piece that shows how complex the science behind COVID is, in the middle of so many contradictory or over-simplified news.

In the book "Why we sleep?", Matthew Walker suggests something similar. That dream sleep is fundamental in making associations. In this case, generalizing and getting rid of overfitting. He talks a bit about problem solving when s

The principle the article is implicitly talking about is Landauer's principle [1]. It states that if information is lost in a system, it must be as heat dissipation. [1] https://en.wikipedia.org/wiki/Landauer%27s_

You can see that your constant is the solution to x=cos(x) (if the equality is true, you can replace the x on the right side with cos(x), and repeat this process). The solution apparently has a name, Dottie constant [1]. [1] https:/&#
