You're judging Nietzsche using circular logic. You're saying that because he's respected by some academics, he is objectively worthy of respect. But that's contingent on those very same academics being worthy of respect.

Problem with non-wireless headphones is that they break. One side of the headphones stops playing sounds; you can sometimes spin the connector and get the sound back, but that gets annoying, and it stops working eventually. The less wires a

I'm wondering how many of the complaints here are to do with FrontPage itself, or the very idea of WYSIWYG web design. To me, it seems that web design is a visual thing. And if so, then a WYSIWYG editor is the appropriate thing to use.

If you like quaternions, you should check out the split-quaternions. They're equivalent to the 2x2 matrices, but help you understand them better by using analogies to the highly familiar and intuitive quaternions.

Nassim Taleb had some negative things to say about GARCH. "GARCH does not work out of sample. It is a good story, but I was unable to use it in predicting squared deviations or mean deviations" I haven't found it in Rob J H

There was a Quanta Magazine article talking about predicting the evolution of a flame-front using ML. The ML algorithm remained accurate for eight Lyapunov intervals; eight times longer than the previous SOTA. https://www.quantam

There is an interesting correspondence between red, green and blue geometries and hypercomplex numbers. The quadratic form in Blue is the norm squared of the complex numbers. The quadratic form in Red is the norm squared of the split-comple

Can someone explain how this works? We've got the following chip companies: Intel, AMD, Samsung. And we've got a bunch of "fab" companies: Intel, TSMC, Global Foundries, Samsung. What's the difference between the tw

I was referring to Kirchhoff's first law which only applies to circuits -- that example is enough to show that I=dQ/dt is wrong. I wasn't considering the cases you're talking about (lightning etc.) because only one examp

The amount of charge in an area stays constant because of Kirckhoff's laws, so dQ/dt=0 always. Wouldn't a better definition be: I = q v . A where q is charge density. A is an area (actually, a normal vector to some fla

The wording is misleading. For the following reasons: - Variolation was common in England at the time. - Wikipedia says that he *inoculated* the boy with smallpox. That means variolation.

He didn't infect him, he variolated him. Variolation normally causes a very mild form of smallpox -- but results in a person becoming immune to the disease. Variolation is the predecessor of vaccination.

There are cases where zero-based indexing is more natural than one-based indexing. An example is naming the centuries: It would be nicer if this were called the twentieth an century instead of the twenty-first. When people talk about the f

Starting at 1 is more intuitive, and therefore IMO better. Regarding some of the advantages of zero-based: - Indexing backwards from the "end". Your language can always add an `end` keyword like Matlab does, and this stops be

Wouldn't it be nice if ELisp were implemented in RPython? What sort of difficulties would this face over the JIT compiler in the link? It would have the advantage that such an ELisp implementation would still be an interpreter (annotat

Apparently, Hamilton defined quaternions as the solution to almost this exact problem. Quaternions are effectively elliptical vectors. That's a lot nicer than defining them in terms of generators and relations. [1] - https:/&#x

Being mummified was a clever move. If his brain were preserved long enough, then he may hypothetically have been brought back to life. A bit like cryogenics.

Just because something is OK -- and has been OK for a hundred years -- doesn't mean it isn't also massively brittle (not that I'm saying it is). You're committing the fallacy of induction when talking about economics.

That's a nice way of looking at it. The trick of adding 1 to the real part doesn't work in the degenerate case where y=-x. In that case, as I said in my earlier comment, an alternative formula is PERP(y)(yx+|yx|). Both formulas ne
