A "Quantum Leap:" From Magnets to "Floating Frogs"
Magnetism has been a
fascination since lodestones were discovered thousands of years
ago. Magnets and magnetism are a central aspect of many of today's
technologies such as motors and generators, medical diagnostic
tools, and data storage. According to physicist, Dr. Jack Crow,
magnets may be the way of the future for high-speed trains.
Crow is director of the National
High Magnetic Field Laboratory (NHMFL) and professor of physics at
Florida State University. Crow will present "Magnet Science and
Technology: From Quantum Wells to Floating Frogs" at a colloquium
at 2 p.m. Tuesday, May 2, at NASA Langley's H.J.E. Reid Conference
A media briefing will be held at
1:15 p.m. in the Wythe Room of the Reid Conference Center, 14
Langley Blvd. at NASA Langley. Media who wish to attend the
briefing should contact Kimberly W. Land at (757) 864-9885.
Crow will present the history of
magnetism with a focus on its application to science and
technology. He believes magnets can be used to float biological
materials, such as a frog, in a weightless state on earth. Crow's
research on quantum wells, highly conductive "electron gas"
regions, in a magnetic field has produced new states of matter,
resulting in two Nobel prizes.
In 1967, Crow received his
doctorate in physics from the University of Rochester. Crow is a
member of the U.S. Department of Energy's Basic Energy Sciences
Advisory Committee and is on the board of editors for
The public is invited to the Sigma
Series lecture at the Virginia Air and Space Center that evening,
at 7:30 p.m.
