KANSAS CITY, Missouri, March 22, 2004 � Space . . . the final frontier. Whether through film or reality, Americans have a growing fascination with space exploration. Weekly, new images float to the earth�s surface from the Hubble Space Telescope, feeding scientists� and on-lookers� desire to learn more. This week Linda Hall Library, the world�s largest public library specializing in science, engineering, and technology, opens its 2004 lecture series with a ��down to earth perspective� on the ever expanding universe.

�The Friends of Linda Hall Library have brought an exceptional speaker to Kansas City,� said Lee Jones%2, president of Linda Hall Library, �Dr. Shane Burns, Associate Professor and Chair of the Physics Department at Colorado College, will probe the continued expansion of the universe.�

Speaker: Dr. Shane Burns, Associate Professor and Chair of the Physics Department, Colorado College

Topic: �Cosmology, Antigravity and the Runaway Universe���%

Background: More than 50 years ago Edwin Hubble and others established that the universe is expanding. Galaxies are rushing apart in all directions. The larger the distance between the galaxies, the larger are their relative "speeds." It seems reasonable that, as time goes on, this expansion should slow down because of the mutual gravitational attraction of the galaxies. However, observations of very distant supernova explosions have revealed that the expansion is not slowing, but is in fact speeding up. This has revived interest in what Einstein called the cosmological constant which causes gravity to be repulsive on very large scales. The discovery has sent theoretical physicists scrambling to try to understand the origin of this strange antigravity effect. Dr. Burns will review cosmology, describe the observations that led to this startling result, and summarize the results of recent Hubble Space Telescope observations of distant supernovae.

When: Thursday, March 25th, at 5:30 p.m. %

Where: Linda Hall Library��%F��s main reading room

"Marilyn is a true asset to Linda Hall Library," said Landon Rowland, a library board member. "Her unusually strong academic and professional background, coupled with her family heritage of deep commitment to Linda Hall Library, will be extraordinary assets as we continue working towards the Library's mission."

Hebenstreit is the third generation of the Bartlett family to serve on the Linda Hall board. Her grandfather, Paul D. Bartlett Sr., was board chairman from 1941 to 1947 and remained on the board until his death in 1964. Hebenstreit's father, Paul D. Bartlett Jr., served on the board from 1956 to 2000.

Hebenstreit holds a bachelor's degree in philosophy from Yale University; a master's degree in development economics from Stanford University%2, and a master%'s of business administration degree in finance from the Wharton School of the University of Pennsylvania.

After spending several years in California working for Wells Fargo and AMPEX Corp., Hebenstreit returned to Kansas City in 1984. She served as vice president and CFO of Brookside Savings Bank, where she was responsible for interest rate risk management and investments.

Hebenstreit is the treasurer of the Kemper Museum of Contemporary Art.

Hebenstreit and her husband, James, are the parents of three daughters.
