Superconductivity a better environmental performance but could also improve public acceptance for expansion of the electric grid. Superconductivity Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic flux fields occurring in certain materials, called superconductors, when cooled below a characteristic critical temperature. It was discovered by Dutch physicist Heike Kamerlingh Onnes on April 8, 1911, in Leiden. Like ferromagnetism and atomic spectral lines, superconductivity is a quantum mechanical phenomenon. It is characterized by the Meissner effect, the complete ejection of magnetic field lines from the interior of the superconductor during its transitions into the superconducting state. The
Heike Shamisen Heike Shamisen The heike shamisen (Japanese: ), is a Japanese musical instrument, member of the shamisen family. Like its other counterparts, the heike shamisen has three strings, a slender neck, a body taut with skin, and it is plucked with a plectrum called a bachi. What is peculiar about the heike shamisen is that it is made particularly for the use in one song, called Heike Ondo, which is a folk song from Shimonoseki, Yamaguchi Prefecture, Japan. As the song calls for a higher range of notes, the heike shamisen is constructed with a shorter neck than conventional shamisen. It
