SUMMARY:Online Beginner's Class
DESCRIPTION:This is a free and open to the public online event\, to attend please register with zoom by clicking here. \nThe 4th session of the Beginners Astronomy Class covers the science behind the telescope. \nHow do our eyes actually perceive objects we see in the telescope and what is the physics that allows that perception. \nFor details\, please visit here and download the sample information PDF package. \nViews: 158

Now we know they represent real things in the sky.\nWhite holes are solutions of the Einstein equations long believed to be unphysical. Can they represent real things in the sky?\n  \n\n  \nCarlo Rovelli is a theoretical physicist known for his work in quantum gravity.  Born in Italy\, he has worked in the United States\, France and Canada. Rovelli is member of the Institute Universitaire de France\, honorary professor of the Beijing Normal University\, Honoris Causa Laureate of the Universidad de San Martin\, Buenos Aires\, member of the Académie Internationale de Philosophie des Sciences. In 1995 he has been awarded the Xanthopoulos Award for “the best relativist worldwide under forty”. He has written global best sellers among which are ‘Seven Brief Lesson on Physics’\, translated in 44 language\, ‘The Order of Time’ and the recent “Helgoland” on quantum theory.  He has been included by the Foreign Policy magazine in the 2019 list of the 100 most influential global thinkers.\nViews: 158

SUMMARY:Online General Meeting - December 2021
DESCRIPTION:This is a free and open to the public online event\, to attend please register with zoom by clicking here. \n  \n\nAn Antarctic Odyssey: Winter-Over at South Pole Station\n\n \n\n  \nIn a lavishly illustrated presentation\, John W. Briggs of New Mexico will describe his year-long experience living at the Geographic South Pole while working for the Center for Astrophysical Research in Antarctica.  In preparation for this at Yerkes Observatory of the University of Chicago\, John was a team member building a 24-inch infrared telescope and related experiments that were set up at the Pole in time for him and colleagues to observe the July\, 1994\, explosive crash of fragmented comet Shoemaker-Levy 9 into the planet Jupiter. \nJohn weathered the “winter-over” with 26 other members of the U.S. Antarctic Program in an experience that many believe approximates what life will be like someday at a lunar or Martian outpost.  Once begun\, South Pole winter-over is an irreversible commitment\, since the Program’s special LC-130 ski planes can’t land in the winter temperatures — in 1994\, sometimes as low as 107 degrees F. below zero (with windchill\, as low as -180 degrees).  John will delight the audience with his perspective on the total South Pole experience — the strange natural environment\, the odd social atmosphere\, and the challenging\, ongoing science. \n  \n\n \nJohn W. Briggs has lived and worked at far-ranging observatories in various technical capacities\, including Mount Wilson\, Yerkes\, National Solar\, Maria Mitchell\, Venezuelan National\, Chamberlin\, and South Pole Station.  He came to New Mexico with his family in 1997 to assist in the final commissioning of the Sloan Digital Sky Survey at Apache Point.  In the 1980s he was an assistant editor at Sky & Telescope magazine and built Bogsucker Observatory in Massachusetts.  He is a member of many astronomical organizations including the Springfield Telescope Makers responsible for the annual Stellafane Convention in Vermont\, and he has recently been elected to the board of the century-old American Association of Variable Star Observers.  His principal activity now involves the Astronomical Lyceum\, an informal museum\, library\, laboratory\, and lecture hall devoted to historical astronomy and its preservation\, located in a 1936 former school gymnasium-theater in Magdalena\, New Mexico.  In the middle 1980s he assisted the late Professor Edgar Everhart\, Director of Chamberlin Observatory\, in his well-known program of cometary astrometry.  John has many old friends in the Denver Astronomical Society.\nViews: 158
