Episode 068 - Fr. Lawrence Machia OSB and Daniel vanden Berk, part I

July 15, 2019
  1. Father Lawrence Machia, OSB, is a Benedictine monk at St. Vincent College and Archabbey in Latrobe, PA. The public can view his 2019 Society of Catholic Scientists presentation on You Tube.
  2. Father Machia’s talk made reference to Galileo’s letter to Benedetto Castelli.
  3. Dr. Daniel Vanden Berk is an associate professor of physics at St. Vincent College.
  4. Fr. Machia and Dr. Vanden Berk, both very interested in astronomy, have worked together on designing planetarium shows on the St. Vincent campus. They have always seen the complementarity of science and religion, faith and reason, in contrast to many people’s rejection of religion based on supposed conflicts with scientific, rational, experiential learning.
  5. Dr. Vanden Berk was intrigued at an early age by the “Cosmos”- series presented on PBS by Carl Sagan, but the program posited a conflict between science and faith.
  6. Among Dr. Vanden Berk’s astronomical adventures: working on the Sloan Digital Sky Survey. He has worked with the Fermi National Accelerator Laboratory, processing data captured by the Digital Sky Survey.

Episode 039 - Star of Bethlehem

December 24, 2018

In this episode we try to give a little workshop on thinking for yourself about a thorny passage in the Bible, specifically what we are to make of this star that supposedly influenced the Magi (wizards? astrologers?) from "the east" to come to Jerusalem looking for Jesus.

Episode 036 - Anne Hofmeister on Galactic Rotation, Math, and Glass

December 3, 2018

The times below are continuations from the last episode. My opening is about 1:30, and then we start with galaxy motions at "26:00".

26:00 Galaxy motions

27:00 Galaxy rotation curves: do not match Keplerian orbits

28:00 Galaxies spin more like records (laggy soft records); mass distribution is nothing like the Solar System

29:00 Hurricanes as a better analogy for galaxies

30:00 Stars in a galaxy move in local organization

32:00 Nebulas

34:00 The opposite extreme: rigid body rotation

35:00 Gravitational attraction between stars creating coherence

36:00 Curiosity that gravity and electrical forces are both inverse square laws

37:00 Poisson's equation

38:00 Summing densities in Poisson's inhomogeneous term is physically meaningless; intensive quantities can't be summed that way

40:00 Gauss' theorem: flux through a surface and quantity within a volume

41:00 Summing is for extensive variables

42:00 Pressure an ambiguous variable

43:00 Future work

44:00 Thermal expansivity: Giauque

45:00 Problems with the glass transition measurements done in the past: need to completely drive out water from the experimental charges

48:00 Wrapup
