This Weekend at The Science Circle: International Observe The Moon Night
Friday, February 26, 2021
Announcement: This Saturday at The Science Circle - "Panel: Gravity"
Saturday February 27
10AM to 11AM SL time
To aid everyone in the audience in getting the most from our presentations, The Science Circle is introducing a series of presentations that seek to explain popular and important topics in different fields of science. Each presentation will start with a basic understanding that most pre-college students may have and gradually work up to the types of things that experts know, and still do not know, about each topic, all within an hour.
For this month’s Panel discussion, the topic is Gravity. Gravity is something so present in our lives that we may take it for granted, but it is also what makes possible some of the most fantastical concepts that explain, and objects that make up, our known universe.
Panel Host Matthew Burr will start by reviewing that we understood about Gravity until the beginning of the 1900’s, based on Newtonian mechanics.
Dr. Phil Youngblood will then review the new ideas that Einstein discovered at the turn of the century regarding the relativity of space-time.
Dr. William Wall will conclude by talking about Einstein’s field equations and the more exotic aspects of gravity associated with massive objects.
On March 20, Phil Youngblood will continue the series with an explanation of “Elementary Particles” at different levels of understanding.

Announcement: This Saturday at The Science Circle - "Celestial Orbits, Part I"
"Celestial Orbits, Part I"
Saturday, February 22nd
at 10AM PST
Here I present the basic physics that underpins the orbits of celestial bodies. Starting from Newton’s laws of motion and gravitation, and using many examples from everyday life, I elucidate fundamental concepts of mass and weight, true and fictitious forces, potential and kinetic energy, and orbital trajectories. This lays the groundwork for future talk(s) on celestial orbits.
Presented by William Wall / Syzygy Asymptote
