Math Encounters — Online:

"Life in Curved Space: From Magnifying Glasses to General Relativity"
with Steve Trettel

Wednesday, January 6 at 4:00 pm ET (New York)

Light endeavors to take the most efficient path between any two points, but matter or geometry can cause this path to bend.  What would life be like in curved space?  Join Steve Trettel, Szego Assistant Professor of Mathematics at Stanford University, as he identifies some telltale signs of curvature in the real world — including spooky ring-like mirages appearing in images from the Hubble Space Telescope — and takes us on a geometrical adventure that leads us to Einstein's great insight: that gravity is not a force, but just a consequence of living in a curved world.

Special introduction by Dr. Richard Schwartz, Chancellor's Professor of Mathematics, Brown University.

Fancy a hands-on experience?  Up the presentation's interactivity with any/all of the following:

  • A small mirror
  • A magnifying glass
  • A clear glass of water, and a straw or pencil

This is a live-streamed event.  Occasional video recordings are made available for a fee at
