The Council on Primary and Secondary Education 2002 summer program hosted 70 pre-college teachers at MIT to attend MIT Physics Professor Walter Lewin's inspired talk about physics. The teachers came from 15 US states and seven countries including Argentina, Austria, Hong Kong, Israel, Lebanon, Norway, and West Indies.

This lecture has been described as one that can make you "see" a rainbow in ways you have never seen it before, and provides answers to questions like "why is the sky blue"?.

During the live lecture, many of the colors discussed were visible as described. However since this lecture was video taped and then compressed in order to create video streams, many of the colors did not survive the compression process. In the lecture hall, viewers did indeed see all of the colors of the rainbow, however once the video is streamed, you will see mostly red and blue. At 14:02, during the rotating disc demonstration, the black and white lines appear brown on the inside and dark blue on the outside, and when reversed, appear dark blue on the inside and brown on the outside. Professor Lewin is introduced by Professor Ron Latanision, Chairman of the Council on Primary and Secondary Education, and Professor of Materials Science and Engineering and Professor of Nuclear Engineering at MIT.

Physics Professor Walter H. G. Lewin is well-known at MIT for his lectures on both Newtonian mechanics and electricity and magnetism. Videos of Professor Lewin's lectures can be viewed on the web via the Open CourseWare and Pivot links below.

Lewin received his Ph.D. in Nuclear Physics in 1965 at the Technical University of Delft, The Netherlands, and has been a member of the MIT Physics faculty since 1966. During his MIT career, Lewin's investigations in astrophysics have included satellite and high-altitude balloon X-ray observations, world-wide coordinated observations of optical and X-ray bursts, and international collaborations observing X-ray sources. In addition, Lewin has collaborated over the years with various artists on sky art events. From 1998 to 2000, Prof. Lewin worked with MIT's Center for Advanced Educational Services on creating the Physics Interactive Video Tutor project -- video help sessions for freshman physics students.
