Physics lectures

morreale Thursday 05 of April, 2012
Professor Walter H.G. Lewin is quite famous for his lectures on physics at MIT. Professor Lewin is heavily involved in studying x-ray sources. He brings astrophysics into his lecture when ever possible. The three lecture series is open source and includes:
In lecture one, he shows the class the film Power of 10 with Philip Morrison, but it does not show up in the video due to copyright issues, but is available on the web (follow the link). An updated interactive version is also available.

Calabi-Yau manifold

morreale Wednesday 28 of March, 2012
I've been reading the Shape of Inner space by Shing-Tung Yau. It's about the geometry of spacetime and super fascinating. It is also integral to String Theory. I was looking up a reference and found this 2D (quasi-3D) visualization of a 6-D Calabi-Yau manifold on the Wolfram website. It's very cool and the gif appears to be animated.

Isaac Asimov Memorial Debate

morreale Saturday 24 of March, 2012
Neil deGrasse Tyson Hosted the 2012 Isaac Asimov Memorial Debate: Faster Than the Speed of Light on March 20, 2012. The debate was sold out with 700 people in the overflow room. The debate was streamed live too and is now available on archive. It was billed as a debate but was more of a discussion about particle physics and the current research be performed to today at CERN. The focus was mainly on neutrinos and the the faster than light neutrinos measured by the OPERA experiment. It was a good discussion, but needed a bit more introduction to the character of the particles being discussed.

26 GWh of power

morreale Friday 23 of March, 2012
This short video describes the March 8-10, 2012 solar storm that hit the Earth. The Coronal Mass Ejection (CME) imparted 26 GWh of energy to the atmosphere. 95% of this energy was reflected back into space by the carbon dioxide and nitrous oxide in the atmosphere.
