Cavendish

One of the most important extensions is the measurement of lateral forces (friction). Friction measurements have accompanied tlie SFA teclmique since its early begiimings in the Cavendish laboratory in Cambridge [37] and a variety of different lateral force measurements are practised throughout tlie SFA conmumity. 

One of the most readily observed reactions in chemistry is the familiar production of bubbles of a colourless gas when certain metals (for example, iron, zinc) react with dilute acids. Cavendish investigated these reactions rather more than 200 years ago, and found the gas evolved to be the same in each case the gas, later named hydrogen, was much lighter than air and when burned in air produced water. 

Gr. hydro, water, and genes, forming) Hydrogen was prepared many years before it was recognized as a distinct substance by Cavendish in 1776. 

These included Scheele, Cavendish, Priestley, and others. They called it burnt or dephlogisticated air," which meant air without oxygen. 

Gr. argos, inactive) Its presence in air was suspected by Cavendish in 1785, discovered by Lord Rayleigh and Sir William Ramsay in 1894. 

The discovery of oxygen, the development of a cleat understanding of the nature of air, and a knowledge of the role of oxygen in combustion and in life processes were historically important scientific achievements. In the 1770s, air and ethers were studied by such scientists as Cavendish, Ptiesdey, and Scheele. Both Scheele and Ptiesdey independendy prepared oxygen. Whereas Scheele s work remained unpubUshed until after his death, Ptiesdey was able to relate his discovery direcdy to Lavoisier in 1775. 

Tritium was first prepared in the Cavendish Laboratory by Rutherford, OHphant, and Harteck in 1934 (2,3) by the bombardment of deuterophosphoric acid using fast deuterons. The D—D nuclear reaction produced tritium ( D-H D — -H energy), but also produced some He by a...

JSPS Research Fellowships for Young Scientists, and K. Tsukagoshi of Hitachi Cambridge Laboratory and R. H. Friend and S. Thomas of Cavendish Laboratory for valuable discussions. 

H. Cavendish established the true properties of hydrogen by reacting several acids with iron, zinc and tin he showed that it was much lighter than air. 

H. Cavendish showed quantitatively that water was formed when hydrogen was exploded with oxygen, and that water was therefore not an element as had previously been suppos. ...
