Pierre Curie (1859-1906), French physicist, was born in Paris on May 15,
1859, and was educated at the Sorbonne. He became professor of general

physics at the Ēcole de Physique et Chimie in 1895 and professor of general
physics at the Sorbonne in 1904. Much of his early work was concerned with the

subject of magnetism in crystals. With his brother, Paul Jean Curie he

investigated piezoelectricity in crystals in 1880. His discovery of a relation for
electrical susceptibility is known as “Curie’s law” while “Curie’s point” is that

critical point of temperature at which ferromagnetism suddenly disappears. He
was run over and killed by a dray, in Paris, on Apr.19, 1906.

SATELLITES

The higher powered satellite amplifiers of the 1980’s made possible TV

transmission into antennas small enough to be mounted on the roof of a private
home or on the side of a building. With such an antenna, ghosting of the picture
