Acetylene of 180°. Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". It was rediscovered in 1860 by French chemist Marcellin Berthelot, who coined the name "acétylène". Berthelot's empirical formula for acetylene (CH), as well as the alternative name "quadricarbure d'hydrogène" ("hydrogen quadricarbide"), were incorrect because chemists at that time used the wrong atomic mass for carbon (6 instead of 12). Berthelot was able to prepare this gas by passing vapours of organic compounds (methanol, ethanol, etc.) through a red-hot tube and collecting the effluent. He also found that acetylene was formed by
New Scientist New Scientist", with Issue 1 on 22 November, priced one shilling (£0.05 as 20 shillings in the £; £ today). The British monthly science magazine "Science Journal", published 1965–71, was merged with "New Scientist" to form "New Scientist and Science Journal". Originally, the cover of "New Scientist" listed articles in plain text. Initially, page numbering followed academic practice with sequential numbering for each quarterly volume. So, for example, the first page of an issue in March could be 649 instead of 1. Later issues numbered issues separately. From the beginning of 1961 ""The"" was dropped from the title. From 1965,
