Coolest Thing I’ve Learned Today
The statement, “every maximal ideal in a commutative ring with identity is prime” is equivalent to De Morgan’s Law, ¬(p ∧ q) → ¬p ∨¬q.
This is cool because De Morgan’s Law is dealing wholly with logic while the statement is talking about (more or less) algebra. Weird.
And if I ever get bored with that, there’s always Euler’s identity:

Video Game Stuff of the Day: Anita Sarkeesian’s Tropes vs. Women in Video Games (Part II)
Yesterday, Anita Sarkeesian unveiled the second episode of her Tropes Vs. Women in Video Games series, which analyzes a variety of tropes that are perceived as sexist in video games.

NeuroLogica Blog » The Continuity Problem →
Fans of science fiction are likely familiar with the continuity problem. You get beamed aboard the Enterprise by the transporter and everything seems to work perfectly. On Earth you are disassembled into your most fundamental particles in order to capture all of the information necessary to then recreate you in your exact state aboard the Enterprise.
The new you aboard the Enterprise is you in every detail, including your stream of consciousness – the thoughts you were having at the moment of beaming. But is it really you? Isn’t it more accurate to say that you were destroyed on Earth and are now dead, and a copy of you was created on board the ship? That is the continuity problem.

John and I talked, I left, and in a week or so he was dead. I cried and I cried, went out and got drunk. And I said, ‘I’m alive, goddammit! I’m alive!’ And I am alive, and I want to make that real for myself. I do face death, but until I’m dead, I’m alive, dammit!
