@RealRajanMehta How about “natural” or “canonical”?

[Will Gyory @WillGyory]

@arm_chirps @gabrielpeyre Hm, is this one of those things that *seems* like it violates locality but really doesn't?

[Will Gyory @WillGyory]

@SharmaneLane @ProbFact Ah ok. I was treating the ratio as <total> : <full house>, but in fact it is <not full house> : <full house>.

[Will Gyory @WillGyory]

@ProbFact Tried to check who was right from this website: https://t.co/5DsPYTgfrS Weirdly, they also say 693:1, but their numbers before that are the same as mine: 3,744 / 2,598,960. Someone's just typing the wrong numbers into a calculator.

[Will Gyory @WillGyory]

@ProbFact I'm getting 694.16666... to 1.

@Blair_Young The nuclear bombs dropped by the US in WWII unleashed about 10¹⁴ joules of energy. Our sun’s gravitational potential energy is around 10⁴¹ joules, which is a billion billion billion times greater.

[Will Gyory @WillGyory]

@Blair_Young I think there's a false intuition that “explosions” must be caused by “explosive material.” But explosive material (like TNT) is just matter with lots of potential energy that can be unleashed quickly. Gravitational potential energy is just as powerful if you have enough of it!

@Blair_Young There's a nice animation of a supernova (and lot's of cool info about neutron stars) in this video. Highly recommended! https://t.co/aquYxMO4j4

[Will Gyory @WillGyory]

@Blair_Young Good question! In short, yes. But I think of it more as a "bounce in, bounce out" process. Gravity pulls the star material to the center, and the intense pressure at the core creates a neutron star. Then most of the star material bounces out, creating a huge explosion.

@waitbutwhy I dunno, there's something instinctual about checking for typos immediately after hitting "send" on anything. Think about texting and the common use of followup "*" texts.

@JDHamkins I've been wondering about this ever since I recently asked a related question on https://t.co/LBMSCJziqG, https://t.co/e1XWJ3Ak8M.

[Will Gyory @WillGyory]

@smartereveryday Spacetime is more fundamental, so let’s say we have already defined that. Then time is (roughly) the spacetime dimension whose sign in the metric signature is opposite to the signs of the other three dimensions.

@MathiasFuchs10 @johncarlosbaez @RogierBrussee Interesting that the precise analysis of this simple idea gets so subtle and complicated.

[Will Gyory @WillGyory]

@johncarlosbaez I think we also need to omit the non–square integrable solutions, like the basic infinite sine plane waves? Or is there a way to expand the usual L²-style Hilbert spaces to include these?

[Will Gyory @WillGyory]

@johncarlosbaez Cool!

[Will Gyory @WillGyory]

@johncarlosbaez What's the Hamiltonian of this theory, and does it agree with E = ℏω?

[Will Gyory @WillGyory]

@AnalysisFact Or rather, for all x ∈ Dom(T) ⋂ Dom(T*), if T is unbounded.

@3blue1brown If anyone's still wondering when this email will arrive, check your spam folder. Somehow it wound up there for me :)
