Also the whole of the Virgin Islands!

I’m RSS-subscribed to a few sections relevant to my research.

The gilded age’s wealthy were also the winners of winner-take-all technologies such as the railroad and oil.

Given the energy scales involved, it's more likely that the issue lies with the approximations DFT makes to quantum mechanics, rather than the approximations quantum mechanics make…

I'm a professor of physics; my research area is computational quantum field theory. I was beginning a new approach for a certain kind of model. I know the model has not been simula…

By the Standard Model of Physics Software you can edit Quarkdown in Atom to get Quarkup and change your Neutron Mail to Proton Mail, but it only works if you type with your left ha…

In case the author is reading this, if you're going to introduce the complex-valued harmonics you should be careful to put the complex conjugate in the inner product = ∫ f(ω)^* g(ω…

Hmm. As a physicist my intuition is that information-preserving transformations are unitary (unitary transformations are 1-to-1). If a compression algorithm is going to yield a bit…

You could package all your data into a zip using this language but you would also have a worthless stretch of memory seemingly filled with noise / things you’re not interested in.

I don't remember much about music theory but I know enough about symmetry to know that there's a mistake in the diagram at 9 o'clock.

Bug report: I tried 6.999999̅ and got false. So there's some nonstandard model of the reals being leveraged here.

Of course that's true, but (in the context of the GP) code's bespoke artisanal nature is not the one most people value.

I have always anthropomorphized my computer as me to some extent. "I sent an email." "I browsed the web." Did I? Or did my computer do those things at my behest?

As a term-rewriting system the rule x-x=0 presumably won’t be in Simplify, it’ll be inside - (or Plus, actually). Instead I’d expect there to be strategies. Pick a strategy using a…

Mathematica has Infix [0], which expresses the adjacency with a ~ (because Mathematica reserves pure blankspace for multiplication). But it works fine to do eg. `"hello"~StringJoin…

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

> The initial focus is to implement a subset of the Wolfram Language so that it can be used for CLI scripting and notebooks. If you have Mathematica installed you can write CLI scr…

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…

IANAL but it seems 3rd-amendment-adjacent.

I'll try to find it; thanks!

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 ce…
