Mathematica has symbolic and infinite-precision addition, so you can't automatically take advantage of obvious compiled code.

They did consider it, got a contract that affirmed that the military would be bound by the same pre-existing terms of service as every other user, and want to resist the military's pressure to renegotiate. Surely that might be naive bu

IANAL but it seems 3rd-amendment-adjacent.

I'm using these to teach an intermediate mechanics class, and my only regret is that there are no problems. The flip side is that sometimes Feynman skips over the derivations of certain things, and that makes good assignments ("F

Careful what you wish for. Negating the predicate of "A COMPUTER CAN NEVER BE HELD ACCOUNTABLE. THEREFORE A COMPUTER MUST NEVER MAKE A MANAGEMENT DECISION" might open us up to the consequence.

Indeed, but if I had called it the Nazi salute I'd have been begging the question---or something like it.

In Germany it hits home when someone gives the Roman salute with an angry scowl on your face during a moment of transition of power.

A dot product is a weighted sum of two vectors, but not in the way the author suggested. The author's use is that one of the vectors is the weights and the other is 'the' vector, so the dot product is the weighted sum of O

No, you cannot escape the conclusion of the limitations on measuring the one-way speed of light. While the video doesn't touch on this explicitly, the discussion of the different path lengths around 25:00 in is about the trigonometric

I was always surprised that when we talk about BHs mass, charge, and spin that we really mean U(1) (electromagnetic) gauge charge and not charges from global symmetries. (If BHs had global charge, you could at least say that this or that b

That’s correct, but being forced out of academia is a good way for scientists to disappear from research and publication.

If you find Jane Goodall inspirational, you may be delighted to learn about Anne Innis Dagg [0], whose studies of wild giraffe predates Goodall's study of chimps. The documentary "The Woman Who Loves Giraffes" [1] is fantast

This map is a neat visualization but is incomplete so far as there are some missing jurisdictions. Puerto Rico and the Virgin Islands, for example.

What if the property with 1 hectare of area were 0.1m x 10^5 m? The meter is bigger than the field is wide. Or, more to the point, suppose someone came with a different system of units and said: look, one of our standard lengths is 10^-6 o

Which is bigger: a meter, a hectare, or a liter?

I agree; the fair comparison is the nth root of the hypervolume in n dimensions, (V(n))^(1/n). This monotonically decreases from n=0, which shows the counterintuitive point that people often want to make anyway: an n-sphere takes up l

This is a nice analog but unfortunately I think it breaks down in a way the "π" calculation does not. In the article 2π(d) = the ratio of the circumference to the radius. This is dimensionless, in the sense that the circumference
