Superconductivity is a fascinating and challenging field of physics.
Scientists and engineers throughout the world have been striving to develop an
understanding of this remarkable phenomenon for many years. For nearly 75 years
superconductivity has been a relatively obscure subject. Until recently, because
of the cryogenic requirements of low-temperature superconductors,
superconductivity at the high school level was merely an interesting topic
occasionally discussed in a physics class.Today however, superconductivity is
being applied to many diverse areas such as: medicine, theoretical and
experimental science, the military, transportation, power production,
electronics, as well as many other areas. With the discovery of high-temperature
superconductors, which can operate at liquid nitrogen temperatures (77 K),
superconductivity is now well within the reach of high school students. Unique
and exciting opportunities exist today for our students to explore and
experiment with this new and important technological field of physics.
