The next generation: New superconducting wires come closer to market

Article Abstract:

The promise of turning high-temperature superconductors into commercial reality has given way to high-temperature superconductor technology involving wires made of the elements bismuth, strontium, calcium, copper and oxygen (BSCCO). A second generation of wires, composed of yttrium, Barium, copper and oxygen with its superconducting qualities in stronger magnetic fields is set to overtake BSCCO.

The shapes of space

Article Abstract:

Henri Poincare, a French mathematician, proves that conjecture holds that the 3-sphere is unique among 3-manifolds and no other 3-manifold shares the properties that make it so simple. Answers to the fundamental questions that topologists can ask about 3-manifolds is discussed.

The many worlds of Hugh Everett

Article Abstract:

The article discusses the various works of Hugh Everett in the fields of quantum physics and military and industrial mathematics. Hugh shifted his focus to military research after receiving major criticisms for his well-proven theory of multiple universes.
