Coulomb, Charles-Augustin de

Japanese: クーロン（英語表記）Coulomb, Charles-Augustin de

Born: June 14, 1736, Angoulême
Died: August 23, 1806. Paris. French physicist. Initially assigned to the West Indies as an army engineer, he returned to Paris due to illness, and retired when the French Revolution broke out, continuing his scientific research in Blois, a rural area. In 1802, he was appointed Superintendent of Public Education. From 1776 onwards, he was involved in the work of establishing metrology, and at the University of Paris, he used a torsion balance to measure the attractive and repulsive forces between charged bodies and between magnetic poles, and in 1785 he discovered Coulomb's law. This law was important in providing a quantitative basis for electrostatics and magnetism, and in recognition of this achievement, the unit of electric charge was named after Coulomb. He also established the law of friction (Amontón-Coulomb's law).

Coulomb
coulomb

The SI derived unit of electric charge or charge. Its symbol is C. 1 C is the amount of electricity carried by a current of strength 1 A per second. The unit is named after the Ca Coulomb.

フランスの物理学者。初め陸軍技師として西インド諸島で任務についていたが病気のためパリに帰り，フランス革命が起こると退役し，地方のブロアで科学研究を続けた。1802年公教育監督官に任命された。1776年以降度量衡制定の仕事に関係，パリ大学でねじり秤によって帯電体の間および磁極間の引力や斥力を測定し，1785年クーロンの法則を見出した。この法則は静電気学，磁気学に数量的基礎を与えた重要なもので，この功績をたたえて電気量の単位にクーロンの名がつけられた。ほかに摩擦の法則（アモントン＝クーロンの法則）を確立した。
