Thus while Mendeleev was able to predict the existence and the chemistry of the missing elements eka-boron, eka-aluminium, and eka-silicon (scandium, gallium, and germanium) with considerable certainty, he was much more tentative when it came to other elements. In his Faraday Lecture of 1889 ...
Transistors had started being mass-produced in the early 1950s, but their use was originally complicated by the material being used—germanium, which was tricky to purify and had to be kept within a precise temperature range. By early 1954, scientists at Bell Laboratories started experimenting wit...
