Still learning...: January 21, 2012.
So ridiculous how your life was cut short. You were doing so much, and it’s so unfair.
It makes me think of those questions: “What would you do if you knew you were going to die in 5 days?” or whatever. I wonder what he would have done. He didn’t know what was going to happen, no one did. But it…
RIP Vlad. You were such an inspiration to everyone who knew you.
A 40-year-old puzzle of superstring theory solved by supercomputer
A group of three researchers from KEK, Shizuoka University and Osaka University has for the first time revealed the way our universe was born with 3 spatial dimensions from 10-dimensional superstring theory in which spacetime has 9 spatial directions and 1 temporal direction. This result was obtained by numerical simulation on a supercomputer.
“According to Big Bang cosmology, the universe originated in an explosion from an invisibly tiny point. This theory is strongly supported by observation of the cosmic microwave background and the relative abundance of elements. However, a situation in which the whole universe is a tiny point exceeds the reach of Einstein’s general theory of relativity, and for that reason it has not been possible to clarify how the universe actually originated.
In superstring theory, which is considered to be the “theory of everything”, all the elementary particles are represented as various oscillation modes of very tiny strings. Among those oscillation modes, there is one that corresponds to a particle that mediates gravity, and thus the general theory of relativity can be naturally extended to the scale of elementary particles. Therefore, it is expected that superstring theory allows the investigation of the birth of the universe. However, actual calculation has been intractable because the interaction between strings is strong, so all investigation thus far has been restricted to discussing various models or scenarios.
Superstring theory predicts a space with 9 dimensions, which poses the big puzzle of how this can be consistent with the 3-dimensional space that we live in.
A group of 3 researchers, Jun Nishimura (associate professor at KEK), Asato Tsuchiya (associate professor at Shizuoka University) and Sang-Woo Kim (project researcher at Osaka University) has succeeded in simulating the birth of the universe, using a supercomputer for calculations based on superstring theory. This showed that the universe had 9 spatial dimensions at the beginning, but only 3 of these underwent expansion at some point in time…”

PAZ: Help Quynh Pay Her Medical Expenses
Quynh Nguyen is a very dear friend of mine. You may or may not know her, but she is someone who is constantly smiling. In fact, a huge part of her identity is her big and beautiful smile.
Unfortunately, she recently discovered that she has TMJ, which is temporpmandibularjoint disorder….

The Hutchinson Mile
For Katehi, it probably felt like a mile for her to go down this long stretch of silently sitting students.

This showed up on my facebook as a picture from a friend of a friend.
WTF is this shit. Happening at MY UNIVERSITY?! FUCK THIS SHIT.
Nonchalant cop.
How can cops like this sleep at night knowing they’ve pepper sprayed 20 year olds in the face? The cop in the back with the small smug on his face pisses me off.
disgusting
so this is America huh.

These all fit me! Especially right now…
