Welding welding was invented in 1893, and around that time another process, oxyfuel welding, became well established. Acetylene was discovered in 1836 by Edmund Davy, but its use was not practical in welding until about 1900, when a suitable torch was developed. At first, oxyfuel welding was one of the more popular welding methods due to its portability and relatively low cost. As the 20th century progressed, however, it fell out of favor for industrial applications. It was largely replaced with arc welding, as advances in metal coverings (known as flux) were made. Flux covering the electrode primarily shields the base
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,
