	Henry Cavendish - Wikipedia, the free encyclopedia
		Henry Cavendish (October 10, 1731 - February 24, 1810) was a British scientist.
		Cavendish is also credited with one of the earliest accurate calculations of the mass of the earth.
		Examples of what was included in Cavendish's discoveries or anticipations were Richter's Law of Reciprocal Proportions, Ohm's Law, Dalton's Law of Partial Pressures, principles of electrical conductivity and Charles's Law of Gases.

		Henry Cavendish, one of the world's greatest scientists, was born in Nice on October 10th 1731, eldest son of Lord Charles Cavendish and grandson of the 2nd Duke of Devonshire.
		Cavendish studied at Cambridge University and became a fellow of the Royal Society at the age of 29.
		Cavendish inherited a fortune at the age of 40 and was driven by an insatiable thirst for knowledge to the exclusion of almost anything else.

	Torsion bar experiment - Wikipedia, the free encyclopedia
		To prevent air currents from interfering, Cavendish set up the apparatus in a wind-proof room and measured the twist (torsion) of the wire using a telescope.
		From the twisting force in the wire and the known masses of the spheres, Cavendish was able to calculate the value of the gravitational constant.
		Since the force of the gravitational attraction of the earth for an object of known mass could be measured directly, the measurement of the gravitational constant allowed the mass of the earth to be calculated for the first time.

		Additionally, Cavendish established an accurate composition of the atomosphere.
		The contemporary accounts of his personality have led modern commentators to speculate that he had Asperger's syndrome.
		Examples of what was included in Cavendish's discoveries or anticipations were, Ohm's Law, Dalton's Law of Partial Pressures, principles of electrical conductivity and Charles's Law of Gases.

		(1731-1810), English chemist and physicist, elder son of Lord Charles Cavendish, brother of the 3rd duke of Devonshire, and Lady Anne Grey, daughter of the duke of Kent, was born at Nice in October 1731.
		Cavendishs scientific work is distinguished for the wideness of its range and for its extraordinary exactness and accuracy.
		Arsenic formed the subject of his first recorded investigation, on which he was engaged at least as early as 1764, and in 1766 he began those communications to the Royal Society on the chemistry oi gases, which are among his chief titles to fame.

		JONES, HENRY (1831-1899), English author, well known as a writer on whist under his nom de guerre " Cavendish," was born in London on the 2nd of November 1831, being the eldest son of Henry D. Jones, a medical practitioner.
		He was a member of several whist clubs, among them the " Cavendish," and in 1862 appeared his Principles of Whist, stated and explained by " Cavendish," which was destined to become the leading authority as to the practice of the game.
		" 'Cavendish' was not a law-maker, but he codified and commented upon the laws which had been made during many generations of card-playing." One of the most noteworthy points in his character was the manner in which he kept himself abreast of improvements in his favorite game.

	Rare First Edition of The Discovery of Hydrogen by Cavendish
		In 1798, Cavendish, by means of a torsion balance, was able to measure the force of gravitational attraction between pairs of lead spheres, thus allowing for the calculation of the gravitational constant, G, in Newton's revolutionary law of universal gravitation.
		Cavendish calculated the force of attraction between the balls from the observed period of oscillation of the balance and deduced the density of the Earth from the force.
		Cavendish was the first to observe gravitational motions induced by comparatively minute portions of ordinary matter.

	THE MICHELL-CAVENDISH EXPERIMENT
		Cavendish also decided to place the whole apparatus in a room which remained constantly shut, moving the weights from the outside and observing the motion of the arm from the outside using a telescope, and this required some further changes in Michell's apparatus.
		Cavendish expresses the opinion that "it seems very unlikely that the density of the earth should differ from 5.48 by so much as 1/14 of the whole." Actually, his (corrected) average of 5.45 is only 1.3 % lower than the currently accepted value of the density of the earth.
		Cavendish, writing in 1798, says it was "many years ago" although Michell did not complete his apparatus until "a short time before his death," which was in 1793.

	Henry Cavendish: Weighing the Earth
		However, Newton estimated this constant of proportionality, called G, perhaps from the gravitational acceleration of the falling apple and an inspired guess for the average density of the Earth.
		His balance was constructed from a 6-foot wooden rod suspended by a metal fiber, with 2-inch-diameter lead spheres mounted on each end of the rod.
		Cavendish's extraordinary attention to detail and to the quantification of the errors in this experiment has lead many to describe this experiment as the first modern physics experiment.

		Henry Cavendish (1731-1810) made fundamental advances in many scientific areas, ranging from his discovery of hydrogen to his famous (and remarkably accurate) weighing of the earth and estimation of its density.
		Cavendish did not stand aloof from other men in a proud or supercilious spirit, refusing to count them his fellows.
		But in the case of Cavendish, the evidence gathered by his biographer is almost overwhelming-and Wilson, writing a century before Kanner and Asperger, had no diagnostic presuppositions, only a wondering admiration and sympathy for his subject.

		At the front of the house was a wooden stage, from which he could climb a large tree to make astronomical observations; a large thermometer on the roof became a landmark for miles around.
