John Archibald Wheeler, one of the great minds of theoretical physics and astronomy, died on April 13 of this year.  He is perhaps best known for popularizing the term “black hole” to describe the collapse of a massive star core upon its death.  He worked with many of the greatest scientists of the 20th century, including Niels Bohr and Richard Feynman.

For those of us who have studied Einstein’s general theory of relativity, Wheeler’s massive book Gravitation (written with Charles Misner and Kip Thorne) holds an important place in the canon.  Wheeler also helped develop the S-matrix technique for calculating the scattering properties of subatomic particles, and (with his student Feynman) an intriguing theory of light emission and absorption known awkwardly as “delayed action-at-a-distance”. He spent most of his career at Princeton University.

Tonight (Monday, April 7) at 7:30, the M. D. Anderson Planetarium presents “Saturn:  News from the Ringed Planet”.  This interactive, informal presentation will discuss the discoveries made over the last 30 years about the planet Saturn, including very recent findings by the Cassini robotic probe.  We will…

• Take a close look at the magnificent ring system
• Zoom in on the surprisingly turbulent cloudy atmosphere
• Explore the wide range of bizarre moons, including smoggy Titan and volcanic Enceladus

The program begins at 7:30 PM.  Admission is $5 per adult, $3 per child under 18, and $10 for a family of 3 or more. Lambuth faculty, staff, and students get in free with their ID.

For the month of April, we have some new things to announce:

• Monday, April 7: The planet Saturn is still bright in the early part of the night, so in honor of the ringed world, we will present a short show on the results from the Cassini robotic probe mission.  Expect some truly beautiful graphics and news about the intriguing ice moon Enceladus.
• Monday, April 21: We present “Black Holes: The Other Side of Infinity”. This program was created by Thomas Lucas Productions in collaboration with Denver Museum of Nature & Science, NOVA and the National Center for Supercomputing Applications. The show is narrated by Liam Neeson, and features truly exciting animations.

Both shows begin at 7:30 PM. Admission is $5 per adult, $3 per child under 18, and $10 for a family of 3 or more. Lambuth students get in free with their ID.
