Conception of laser-generated filaments for lightning control.

When something unexpected happened during Aaron Bernstein’s laser experiment in ionization, he veered from the original experiment, followed the surprise and found something he calls “pretty darn cool.”

What Bernstein, a scientist in the Department of Physics at The University of Texas at Austin, and his colleagues found was that they could cross two laser beams in ambient laboratory air and transfer seven percent of the energy of one of the beams to the other.

Eureka! I didn’t find it

Steven Weinberg

Scientists search for new knowledge. They want to find out how things work—from inside cells to the edge of the universe.

So they’re disappointed when they don’t find what they expected or nothing at all, when nature throws them a curve when they expected a fastball.

Not necessarily.

Steven Weinberg, the Nobel Prize physicist at The University of Texas at Austin, hopes that the Large Hadron Collider (LHC) strikes out.

Basically, he said, what’s the fun in finding what you’re looking for? It’s

Austin swings like a pendulum do

Most Foucault Pendulums are in places where they can be seen: in science museums or the lobbies of the buildings of university physics departments.

The one at The University of Texas at Austin is a bit off the beaten path. It’s on the far east side of campus in the Development building, which houses the university’s development offices, the Charles Dana Center and a health clinic.

But it still gets traffic.
