Awesome Physics Teacher Dan Burns Explains Gravity In A Way Anyone Can Understand (VIDEO)
General relativity, the geometric theory of gravity developed by Albert Einstein in the early 1900's, is today considered one of the twin pillars of modern physics. Along with quantum mechanics, it is fundamental to our understanding of the universe.
Yet despite its importance, general relativity doesn't always get the classroom attention it deserves.
"Is general relativity in the state standards? No. Probably the crowning achievement of science not in the state standards," Dan Burns,
a physics teacher at Los Gatos High School in California, says in the
video above. But that didn't stop Burns from coming up with an ingenious
demonstration to help students understand concepts that are notoriously
tricky.
As Burns explains in the video, which was posted by apbiolghs on YouTube,
matter bends space. He demonstrates that idea with the help of a
stretched sheet of lycra, a pair of weights, and a few marbles. When set
in motion on the lycra, the smaller marbles circle the much heavier
weights, coming closer with each turn until they connect.
The video helps students wrap their minds around a number of complicated concepts. Class is in session!
Dan Burns explains his space-time warping demo at a PTSOS workshop at Los Gatos High School, on March 10, 2012. Thanks to Shannon Range from the Gravity Probe B program for creating the original demonstration which he shared with Dan in 2004.
