Boaz Almog “levitates” a superconductor

Friday, July 6th, 2012

How can a super-thin 3-inch disk levitate something 70,000 times its own weight? In a riveting demonstration, Boaz Almog shows how a phenomenon known as quantum locking allows a superconductor disk to float over a magnetic rail — completely frictionlessly and with zero energy loss. Experiment: Prof. Guy Deutscher, Mishael Azoulay, Boaz Almog, of the High Tc Superconductivity Group, School of Physics and Astronomy, Tel Aviv University.

Boaz Almog uses quantum physics to levitate and trap objects in midair. Call it “quantum levitation.”

Elyn Saks: A tale of mental illness — from the inside

Friday, July 6th, 2012

“Is it okay if I totally trash your office?” It’s a question Elyn Saks once asked her doctor, and it wasn’t a joke. A legal scholar, in 2007 Saks came forward with her own story of schizophrenia, controlled by drugs and therapy but ever-present. In this powerful talk, she asks us to see people with mental illness clearly, honestly and compassionately.

Elyn Saks asks bold questions about how society treats people with mental illness.
