On 12 and 13 April, Lawrence Krauss returned to YBC to give a general lecture and a 2-day mini course, which were a big success. On Monday morning, Lawrence gave a 90-minute general lecture on dark matter in the universe, explaining that only about 15% of the matter in the universe (stars and galaxies) is visible -- and that the vast majority of matter is invisible "dark" matter and dark energy, which is detectable only indirectly by the gravitational effect they have on visible stars and galaxies. He gave an introduction to what dark matter is all about, how researchers predicted its existence and projects that are ongoing to directly detect dark matter and its composition. On Monday and Tuesday afternoons, Lawrence taught the physics class, doing a review of simple harmonic motion and waves, from a different perspective. Akzo Nobel Adhesives division and Atlas Copco Tools were the co-sponsors of Lawrence's lectures.

Next month, on 24 and 25 May, physicist Frank Wilczek (Nobel Prize in Physics, 2004) will give a morning general lecture on the search for new subatomic particles at the Large Hadron Collider at the CERN lab in Switzerland. Then, on Monday and Tuesday afternoons, he will again teach the physics class, doing a review of the chapters the students will have just finished studying. Frank Wilczek is considered one of the world's most eminent theoretical physicists. He is known, among other things, for the discovery of asymptotic freedom, the development of quantum chromodynamics, the invention of axions, and the discovery and exploitation of new forms of quantum statistics (anyons). Akzo Nobel Adhesives division and Atlas Copco Tools are the co-sponsors of Frank's lectures.
