LRC Lectures

 

The LRC lectures are recorded from live presentations, and presented here for educational purposes. This is the first lecture in a monthly lecture series held in Clearfield, Utah. It is divided into three parts. A discussion forum is included in which viewers can leave comments and ask questions.

A link to the PowerPoint slides is here: On the Coming Revolution in Fundamental Physics: What is String Theory?

On the Coming Revolution in Fundamental Physics
33:41
Discussion of Dave Gross’s Presentation on String Theory

 

Errata: Dewey Larson’s Alma Matter is Oregon State University, in Corvallis, not the University of Oregon, in Eugene, as stated in the video.

04 Mar 08 - Part III of III

On the Coming Revolution in Fundamental Physics III
25:50
Part III of III part discussion of Dr. David Gross’s Presentation

Note: Most of the video for this last part was lost, and the audio is poor. It will be cleaned up later. Also, the equations, which look right in PowerPoint, were messed up by the upload to the Internet, which doesn’t accept superscripts correctly.

 

The second lecture in the series, Lecture 2, entitled “Where in the World is SUSY?” focuses on man’s search for answers, using CERN’s soon to be completed Large Hadron Collider. As the LHC comes up to speed sometime late this year, or early next year (it’s a few years behind schedule), clues to what lies beyond the standard model hopefully will emerge. The major theoretical issues are discussed and it is explained how big a part extra dimensions plays in the drama surrounding this effort. Finally, the LRC’s unique approach to the concept of dimensions, in terms of multi-dimensional motion, is presented.

Note: Strictly speaking, the sum of the nD +/- 13 directions in the 2x2x2 cube is only 13 dimensions, with 2 directions per dimension , not 26 dimensions. However, there are 26 independent linear spaces in the cube, which, in a sense, represents 26 degrees of freedom that can be thought of as dimensions.

Also, when we consider the symmetry of space and time, then the space dimensions are the inverse of the time dimensions, which is another way of viewing the 26 dimensions: 13 space and 13 time dimensions. In addition, if we double the first tetraktys, effectively taking us to the second tetraktys in Pascal’s triangle (to 24-27), we arrive at the number 26 again. Not that we have to find 26 dimensions in the tetraktys, but it is an interesting fact that they are there and that string theory mathematics is based on the Grassmann numbers.
