Re: Why does light move at the speed it does?

I call "c" the "asymptotic speed limit", since that's what Lorentz transformations do to increasing speeds.

I call 1 divided by the Planck time the "frame rate of the Universe" for similar reasons.

Would a tiger make a good pet for Paul Bunyan?

Tigers are bad pets for humans because they are dangerous. But if we were much larger than a tiger, would we have a relationship with them as we do now with housecats? Housecats are vicious killers, too; we're just much bigger than them. How similar is tiger behavior to, say, the wild cats from whic...

Re: Breaking Earth's gravity well

The Schwarzschild radius of a black hole is the distance from the center within which the escape velocity is >= c. Why can't you escape from a black hole with continuous acceleration?

Re: Why aren't any good cryptosystems NP-complete?

I've always found Lamport signatures interesting in that they can turn any hash function / complicated mess of a function into a public-key signature scheme. The apparent downside seems to be that you need to remember some information about previous signatures in order to use it properly, and that u...

Re: Why aren't any good cryptosystems NP-complete?

With modern SAT solvers, what would happen if you asked it to reverse the SHA-256 algorithm? Or asked it to factor a big number?

Re: Gravitons

I'm personally still trying to understand why gravity is considered special in general relativity. Einstein's thought experiment about being an elevator and not being able to distinguish from inside resting on Earth versus accelerating "upward" at 9.8m/s^2 seems like it would apply to the ...

Why aren't any good cryptosystems NP-complete?

I was thinking about cryptography and complexity theory and wondered something: why aren't any good asymmetric (public-key) ciphers based on NP-complete problems? The three most popular public-key algorithms are based on factorization, prime-order finite field discrete logarithms, and elliptic curve...

Trick math problems?

Anyone learned some "trick" math problems over their years as a nerd? Here's one I remember from high school:

Simplify (x - a)(x - b)(x - c) ... (x - z).

Re: [SAFESPACE] LGBTIQQ Thread - Queer Support!

I'm MTF trans, still in transition, on hormones 2 years. I'm having a hard time coping in life. I look like a guy and I don't think that there's anything I can do about it. I'm depressed all the time, and frequently cry in the morning before work, making me late to work. I see a therapist and a psyc...

Re: Female disinterest in STEM

I wonder where I fit into this. I'm a programmer/reverse engineer, you know, assembly language and stuff, yet I'm MTF transgender. I have at least a partially female brain or I wouldn't feel this way, but I don't seem to have female interests.

Re: what would you choose as your super power?

The only super power I want is the ability to change my gender. In fact, there's nothing I want more in life than that. It hurts me so much to be a man :cry:

Re: Question about the speed of light

The belief that the speed of light is exactly the same as the speed limit of the universe basically comes from the observation that photons in a vacuum travel at the same speed in every reference frame. Then the arguments from special relativity show that this is also the limit on how fast a massiv...

Question about the speed of light

I have a physics question that none of my friends knows the answer to. By Special Relativity, there exists a constant usually named "c" that is the asymptotic speed limit of the Universe as we understand. That this constant exists and its value are both theoretically and experimentally sho...
