Enough moaning about basketball - yvonne - 03-17-2014
Here's the latest win for Nerd Nation
Quote:...scientists announced Monday a breakthrough in understanding how our world as we know it came to be.
....
"It teaches us something crucial about how our universe began," said Sean Carroll, a physicist at California Institute of Technology, who was not involved in the study. "It's an amazing achievement that we humans, doing science systematically for just a few hundred years, can extend our understanding that far."
What's more, researchers discovered evidence for the first time of what Albert Einstein predicted in his general theory of relativity: Gravitational waves.

If you're interested in what this all means and want it at a level that's pretty significantly higher than what you'll find at CNN, the quoted physicist (Sean Carroll) has an explanation on his blog: http://www.preposterousuniverse.com/blog/2014/03/16/gravitational-waves-in-the-cosmic-microwave-background/. Fair warning, I'm a physicist and a lot of it was over my head.
Phil Plait has a more accessible (but less in-depth) take here: http://www.slate.com/blogs/bad_astronomy/2014/03/17/evidence_of_inflation_astronomers_detect_gravitational_waves_from_the_early.html

All I want to know is if this will help keep Dwight Powell out of foul trouble and help get the ball into Chiney on the low post.Â
If it will, great.Â
If it won't, is it really all that important in the grand scheme of things...? ;D

Thanks, stupac, that second one was at a level that even I could understand.

Check out this touching video where Andrei Linde (one of the fathers of inflation) is told about the result. It is also great to see the excitement on the face of this wife (who, by the way, I had for 3 quarters, and while a sweet woman, not the best of teachers...).
I've been so excited the whole day, can't stop reading papers and blogs!

Most of the articles didn't explain why the individuals being quoted were quoted. I was curious who is behind this research. I found an explanation of who was involved at http://www.cfa.harvard.edu/news/2014-05:
Quote:BICEP2 is the second stage of a coordinated program, the BICEP and Keck Array experiments, which has a co-PI structure. The four PIs are John Kovac (Harvard), Clem Pryke (UMN), Jamie Bock (Caltech/JPL), and Chao-Lin Kuo (Stanford/SLAC). All have worked together on the present result, along with talented teams of students and scientists. Other major collaborating institutions for BICEP2 include the University of California at San Diego, the University of British Columbia, the National Institute of Standards and Technology, the University of Toronto, Cardiff University, Commissariat à l'Energie Atomique.
BICEP2 is funded by the National Science Foundation (NSF). NSF also runs the South Pole Station where BICEP2 and the other telescopes used in this work are located. The Keck Foundation also contributed major funding for the construction of the teams telescopes. NASA, JPL, and the Moore Foundation generously supported the development of the ultra-sensitive detector arrays that made these measurements possible.
Looks like it took cooperation and funding by a lot of public and private institutions.

Oh man, was she the person who taught QFT? If so, I very much agree with your take, not an inspiring teacher. But at the same time, that material is hard. I never really got it and dropped the series after the first class. At this point basically all I remember is that the math for renormalization is horrible.
