Looking through the glass transition on an ultrafast timescale

Posted: 14 Apr 2012 09:57 AM PDT

When chemists look at a drinking glass filled with water and a few ice cubes, it's not clear to them whether the glass is more like the water or the ice.

Glass is one of civilization's most valuable and versatile materials. To scientists, it's also one of the most intriguing, because it displays properties of both solids and liquids.

Coherent Electron Cooling: Combining Methods to Cool Particle Beams and Increase Collision Rates at RHIC

If you can crash more particles into each other at Brookhaven Lab’s Relativistic Heavy Ion Collider, you can collect more data from the subatomic wreckage. More data is just what researchers need in the hunt for answers to some of the universe’s biggest mysteries as they investigate the “perfect” liquid quark gluon plasma (QGP) revealed by previous RHIC collisions and search for the origin of proton spin. These experiments help them understand what the universe was like moments after its creation and how it evolved to become what it is today.
