NOVA | Einstein's Big Idea | Relativity (Lightman Essay) | PBS
http://www.pbs.org/wgbh/nova/einstein/relativity/

This website contains a lot of good information, but it is not overwhelming, which makes it easy to read. Also, it has illustrations that help you to understand the theory of relativity. It is credible because it was written by a physicist and includes a photograph of him and personal information to confirm that he is an actual person.

This article is about realativity and the cosmos. It gives a background on the essense of gravity and the goes on to tell more about stars. I chose this site because I know that PBS is a trustworthy orgnaization.

this site seems to be very reliable. i chose it because it was one of the first links to come up as one of the most used by other students. it seems to be written by an expert as well.

Light can be stopped and restarted?

i don't understand how cooling Na helps stop light - or what the "signature" encoded in the light is ...

Harvard brainiac Lene Hau uses Bose-Einstein condensates to "freeze" light, stopping it and effectively storing it as matter.

Measurement of quantum phenomena could be affected by fractal nature of the object being measured.

For those keen to know more: the computations involve "envisioning space and time as part of a four-dimensional crystal lattice, with discrete points spaced along columns and rows."

"Until now, this has been a hypothesis," France's National Centre for Scientific Research (CNRS) said proudly in a press release.

According to the conventional model of particle physics, protons and neutrons comprise smaller particles known as quarks, which in turn are bound by gluons. The odd thing is this: the mass of gluons is zero and the mass of quarks is only five percent. Where, therefore, is the missing 95 percent? The answer, according to the study published in the US journal Science on Thursday, comes from the energy from the movements and interactions of quarks and gluons.
