String Theory for Pedestrians Part III
on: CERN
In this 3-lecture series I will discuss the basics of string theory, some physical applications, and the outlook for the future. I will begin with the main concepts of the classical theory and the application to the study of cosmic superstrings. Then I will turn to the quantum theory and discuss applications to the investigation of hadronic spectra and the recently discovered quark-gluon plasma. I will conclude with a sketch of string models of particle physics and showing some avenues that may lead to a complete formulation of string theory.

Unsolved Problems In Biomedical Materials Engineering
on: Caltech
Dr. Julia A. Kornfield, Associate Professor of Chemical Engineering at Caltech, and Dr. David A. Tirrell, Ross McCollum-William H. Corcoran Professor of Chemistry and Chemical Engineering at Caltech, presented this lecture as part of the 0.1 Seminar series. They discuss some of the complications and challenges that arise in the clinical use of medical devices that are surgically implanted each year, and present some current approaches to the amelioration of the resulting problems.

Jamie Ward

The Geometry of Sound
on: sciencelive
Earlier in the week Liz spoke to Dr Jamie Ward, about synaesthesia, a condition where people see shapes and colours when listening to sounds. This session shows us that that's not as crazy as it may sound. Liz talks to Trevor Cox, Professor of pure mathematics at the Open University and Gresham Professor of Geometry in London and Robin Wilson, professor of acoustic engineering at Solford University about the shape of sound. Trevor Cox tells us how a concert hall shapes the sound within it and how the acoustics engineer works out the perfect acoustics for a space. Robin Wilson explains how the ancient Greeks linked maths and music and traces the progression of musical symmetries from ancient Greece to modern days.

Universally Accessible Demands Accessibility for All of Humanity
on: Google Video
Google serves a minority of humanity reasonably well today. How is Google going to fulfill its mission to deliver the world's information usefully and universally? Character recognition and accessibility pioneer Jim Fruchterman presents his quest to make information accessible to the long tail of humanity (which stillincludes most of the 'bulge!' From inventing omnifont character recognition and affordable reading machines for the blind to creating accessible digital libraries for the blind and using technology to teach literacy to people who have fallen through society's cracks, Jim will cover the technical and practical challenges to reaching all of humanity with accessible information.

S. Carroll
University of Chicago
Cosmology for particle physicists Part II
on: CERN
The past few years have seen dramatic breakthroughs and spectacular and puzzling discoveries in astrophysics and cosmology. We know much about the universe, but understand very little. Open questions include the nature of the dark matter and dark energy, the origin of the matter/antimatter asymmetry, the possibility of inflation, and the role of string theory and extra dimensions in the early universe. All of these issues impact strongly on, and will be heavily influenced by, upcoming experiments in particle physics.

Interview
on: The Vega Science Trust
In 2000 Herbert Kroemer, who was born in Germany, and works at UCSB in the USA shared half of the Nobel Prize for Physics with Zhores I. Alferov ( Russia ) 'for basic work on information and communication technology' and in particular 'for developing semiconductor heterostructures used in high-speed- and opto-electronics'. The second half of the prize went to Jack S. Kilby, USA 'for his part in the invention of the integrated circuit'.
