Compton Lectures

Arthur H. Compton Lectures

The 81st Compton Lecture Series

Every Saturday morning beginning April 4, through June 6, 2015; lectures start at 11:00 a.m. (No lecture on May 23rd [Memorial Day weekend]).

Lecturer: Andrew McCann, EFI Postdoctoral Scholar 
Topic: "Nature's Timepiece: The Exotic World of Pulsars"

Kersten Physics Teaching Center
5720 S. Ellis Avenue, Room 106
Chicago, IL 60637

Neutron stars are born in the final moments of the supernova death of massive stars and, in keeping with their exotic origin, they exhibit unmatched extremes in a variety of ways. Not only are they the smallest stars we know of, neutron stars are the most dense solid objects in the known Universe. Their surface gravity is 100 billion times that of the Earth and their magnetic fields’ strengths, which can reach 1015 Gauss, are the strongest known to exist. Neutron stars are born rotating rapidly and their emission, like the beam from a lighthouse, is observed as a highly stable and regular periodic pulsation - hence the name 'pulsating star' or 'pulsar'. Although pulsars were discovered over 40 years ago and the number of known pulsars exceeds 2400, the physical processes which power the vast array of unique and often bizarre phenomena observed from pulsars are poorly understood. Explaining the observed behaviour of neutron stars has become one of the most challenging puzzles in high-energy astrophysics. Despite the longstanding mystery of their emission, the steady and predictable pulsations from pulsars make them remarkably powerful astrophysical tools. This duality has put pulsars at the centre of some of the most compelling astrophysical research of the last few decades.

Each week we will explore different aspects of this duality, by reviewing pulsar phenomena in different wave bands (radio, optical, x-ray, gamma-ray) and by discussing the role of pulsars in tests of Einstein's theory of relativity and in the search for gravitational waves.  No scientific background is required -- just bring your curiosity. 

Purpose of the Compton Lecture Series

The purpose of these lectures is to make accessible some of the remarkable recent developments in physical science to the non-specialized public, and to share with laymen some of the intellectual and cultural excitement associated with scientific developments that may affect in some way the lives of all of us and are a significant part of our cultural heritage. The lectures often, but not exclusively, are focused on areas of research being pursued at the Enrico Fermi Institute.

The idea of these lectures originated with John Simpson when he was Director of the EFI and holder of the Compton chair. Funds from a bequest of John W. Watzek, a good friend of Compton, supported the lectures from 1976 through 1986. Presently, funding is provided within the budget of the Enrico Fermi Institute, with much welcome additional support from C. Spencer Powell.

From the outset, Compton lecturers have been nominated by the Director of the EFI from the group of young scientists active in research as Fellows or post-doctoral associates. It is this group, which is in many cases at the center of research, that attacks frontier questions with a fresh view and new ideas. Awarding the Compton Lectureship to the best of these scientists is in general appreciated as a sign of recognition and encouragement that seems more important than the modest stipend also included in the award. Compton lectures are neither given by graduate students nor by full-time faculty members.

Compton lectures are presented in every Spring and Fall quarter; each set of lectures comprise 10 one-hour presentation on successive Saturday mornings in the Kersten Physics Lecture Hall. The lectures are advertised through letters and posters sent to area high schools, libraries, colleges and to individuals, through local newspapers and radio stations (WFMT), and by word of mouth. Depending on the popularity of a particular lecture (or topic), the attendance varies from fifty to "standing room only", and includes people with a wide variety of backgrounds: from faculty to laypersons, and from Hyde Parkers to commuters from distant suburbs.

Of the 78 lecturers since 1976, ten have held faculty positions at the University of Chicago, and many now have faculty positions elsewhere. There are at least two books (Robert Wald - Space, Time and Gravity, UC Press, 1977) and (Nickolas Solomey - The Elusive Neutrino: A Subatomic Detective Story, Scientific American Library, New York, 1997) which grew out of a set of successful Compton Lectures.
