Announcement: This Saturday at The Science Circle - "Panel: Gravity"

 

"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.

“Gravitational Waves: The 2017 Nobel Prize in Physics”
Presented by Rob Knop Ph. D, USA          

The 2017 Nobel Prize in Physics was awarded to leaders of the LIGO collaboration for the discovery of gravitational waves.  This phenomena was predicted a century ago by General Relativity, but it was always known that because they’re typically so small, they would be very hard to detect. 

Indirect evidence for them previously came from the decaying orbits of binary pulsars.  In 2015, the LIGO detectors announced the first direct detection of gravitational waves, a signal resulting from the merger of two very distant black holes. 

In this talk, I’ll describe the nature and history of gravitational waves, and the work that the large LIGO collaboration did to earn this Nobel prize.

“May the Gravitational Force Be With You”
by Paul Doherty aka Patio Plasma, USA

In this lecture, travel from Galileo’s dropped balls, through Newton’s apple-moon, to Einstein’s warped spacetime. Discover that gravity warps the GPS system, that satellites use gravity to “see” underground and measure California’s groundwater, and that gravitational waves can be used to watch black holes collide and merge.

SL Video" Gravity Is A Mistake"

Click here if the video fails to play

By Haveit Neox on June 6, "Eupalinos Ugajin's 'Gravity is a Mistake' is a full sim exhibit in the virtual world of Second Life®. His sim and artwork fill the stage for a levitating experience. Included are guest artists whose pieces dot the environment. Always highly scripted, one never knows in what circumstance they will find themselves next, except for one, they will quickly discover that gravity is a mistake.

"The installation continues till the end of June 2016 on the LEA21 sim in Second Life®

"If I am able to get a full list of the participating artists, I'll post them here. As the exhibit is up for three more weeks, Eupalinos may welcome yet more artists to add their work, in which case the list grows."

Press Release: Talking Science on Thursday - Gravity and Astrodynamics

This week's Talking Science will be about one of the fundamental forces of nature: gravity. In particular, we are going to talk about how scientists and engineers use rockets with and against gravity to send spacecraft all over the Solar System. So we'll be talking about such arcane things as geostationary orbits, Hohmann Transfers and Lagrange Points. Along the way we'll learn about folks like Kepler, Newton and Einstein. There might be a teeny bit of math too.
