I'd love to see the teaching video!

You could be right, but the way I read it is that those are things that everyone already knows, so there is no point in spelling them out.

In the words of Robert Morris, 40 years ago: "The three golden rules to ensure computer security are: do not own a computer; do not power it on; and do not use it."

In some cases these are not available. For instance, archive.org has many books that don't seem to be available anywhere else.

Oops, my mistake: that is not the definition of curvature! The outer derivative must be taken with respect to arclength, rather than with respect to t.

Do you know whether it's usual nowadays in industrial design to make curves that are actually smooth (I mean, derivatives of all orders are continuous) and not just C2? Or is it technically challenging for some reason, or not useful?
37.
by yshklarov 4y ago
That is roughly correct. For a curve with smooth parametrization f(t) = (x(t), y(t)), with f'(t) ≠ 0 for all t, the curvature at the point f(t) is defined to be κ := |(f'(t)/|f'(t)|)'| -- the magnitude of the first

We're bipedal animals by nature, but not every individual is able to walk. Likewise, although we're social animal by nature, not every individual can easily form close social ties. There are many reasons a person might struggle to

Actually, the "fluff" in this case is outstanding. The paper itself doesn't provide much context, but the Quanta piece does a great job at explaining why the result is important.

But no! The very first sentence clearly states: "In this post, we'll look at the natural problem of how to communicate an estimate of a real value in [0,1], using just 1 bit." The second paragraph sketches the motivation for

Indeed. "Many widely-accepted theories ultimately get rejected. Perhaps this one will be, too." What use is an article like this to anyone?

A fair point, but don't you think it sidesteps the matter at hand? Never mind that other systems have flaws, too. What are the specific reasons that Node.js itself is hated?

I see lots of comments arguing with the post, but seeing it in its original context is important. The full article addresses many of the criticisms: The roots of creativity and genius http://super-memory.com/articles/ge

The article purports to teach calculus, so it should get the basics right. The Fundamental Theorem of Calculus is called fundamental for a reason: it's the most important concept in the entire subject. It's not just a technicality

I'm not sure what this has to do with the content of the article. Could you elaborate?

This is fantastic, I love it! I've been looking for something like this. Your definition of "uniform" doesn't look quite right: It's not enough for the symmetry group to be vertex transitive, you also have to requir

You are asking big questions! My answer is brief but I hope it helps a little. By axiomatizing a definition we can begin to prove theorems rigorously. If we formally abstract a concept and deduce formal statements from it (which can themsel

I don't understand why so many people recommend baby Rudin (Principles of Mathematical Analysis). The presentation in Rudin is not merely terse, but also quite dry and unmotivated. I suggest you avoid it--regardless of how much talent

This is an absolute joke. Take a look at the data. https://sci-hub.hk/https://www.sciencedirect.com/science/art... The sample size is far too low to draw any conclusions. Only a small handful of rats in

Taking this to the extreme, you could "store" 65535 1-bit values in one 16-bit value. You just have to keep track of how many of them are equal to 1.
