Jacobs School of Engineering Pi-Mile Run/Walk →

This may be how I’m going to celebrate Pi day this year. I’ll make sure to wear a physics majors » engineering majors shirt that day. Ooorrr, even better, wear my pi shirt and put a note on the back with the above statement :)

supercuddlypuppies replied to your post: supercuddlypuppies replied to your post: Do you… source? I feel like the logic here is backwards. black holes that have a lot of energy may tend to be rotating, but I don’t see how you would dissipate that to become non-rotating. Is there a mechanism that preferentially removes angular momentum? All the information I’ve presented has been from...

supercuddlypuppies replied to your post: Do you know anything about black hole evaporation and what causes that to occur? why do they have to be non-rotating? A rotating black hole has enough energy to collect matter in the space outside of its horizon, and this matter then tends to fall into the black hole. Because of the black hole’s strong gravitational pull, the amount of incoming mass...

I knew that neutrinos travelling faster than photons couldn’t be true…

Anonymous asked: The pictures of space you put up on your wall, did you just print them or cut them out of magazines or what? Where did you get them from? I love them.

Phantom Black Holes of the Milky Way

The effect of a primordial black hole hitting the Sun ought to be easily observable, say physicists at New York University and Princeton University, noting what we think might be the obvious. But they go on to suggest that such an event wouldn’t be as catastrophic as it sounds. The likelihood is that a primordial black hole with mass of an asteroid or comet would pass straight through the Sun,...

Anonymous asked: What college are you in at UCSD? I'm going there soon for a major in astrophysics, but I have no clue what college I want to be in (even after all the research I've done of the 6 colleges!).

Stephen Colbert: What is the most beautiful thing that you know of in science?
Neil deGrasse Tyson: E = mc2.
Stephen Colbert: Really?
Neil deGrasse Tyson: Oh, it's awesome. It is.
Stephen Colbert: So that equation doesn't just have a great publicist? It's actually...? Because everybody knows it, but also everybody knows Coke. It's like the Coca-Cola of science.
Neil deGrasse Tyson: Yeah, you learn [it] before you even know what any of those symbols mean. You hear it in elementary school. It's a gorgeous thing.
Stephen Colbert: What is beautiful about [it]? First of all, tell everybody what all the pieces mean. 
Neil deGrasse Tyson: E stands for energy. M is mass. C2 is just the speed of light squared. Ignore that for the moment. The thrust of that equation is that energy and mass are equivalent to each other. Which means you can transmute one into the other and back. What makes that extraordinary is that [that] hardly ever happens in our everyday lives, yet it's going on all the time in the rest of the universe.
Stephen Colbert: So we're in this little pocket where e = mc2 is not visible?
Neil deGrasse Tyson: Never happens. It's not visible. It's not happening in our lives, no. But if it did, the world would be really different.
Stephen Colbert: What is beautiful about it to you?
Neil deGrasse Tyson: It's simple. It's simple yet it accounts for hugely complex things. And for me that is where the beauty lies in the truth.
