9 Mar 2015, 11:00 UTC (From Astro 127) By Dr. Kelsey Johnson The 2nd annual Heidi Winter Memorial Lecture. Wed, Feb 11, 2015, NRAO Auditorium. The 8 mysteries: - 8: What is dark matter? - 7: What is dark energy? - 6: What happens inside black holes? - 5: Are we alone? Is there other life in the Universe? - 4: Are there other dimensions? - 3: What determines the laws of nature? - 2: Is the Universe "Fine tuned"? - 1: What caused the beginning of the Universe? The mysteries Kelsey had to leave off for time reasons: - 10: What is the nature of time? - 9: What is the shape of the Universe? Clarke's 3 laws: - If a distinguished but elderly scientist says something is possible, he is almost certainly right. If he says it's impossible, he's very probably wrong. - The only way of discovering the limits of the possible in to venture a little way past them into the impossible. - Any sufficiently advanced technology is indistinguishable from magic.

18 Feb 2015, 12:00 UTC https://www.youtube.com/watch?v=2lCOITp43FM Streamed live on Feb 11, 2015 Dr. Pamela Gay hosts. Guests are Dr. André David Tinoco Mendes (research physicist at CERN, Geneva) and Dr. Denis DaMazio (Brookhaven National Labs). Everything in our universe is made up of a very small numbers of particles, and is controlled by just four forces. In this Hangout, we will discuss these basic building blocks of everything.
