If women do the same job for less money, why do companies hire men to do the same job for more money?
It's a puzzlement!
FluorineIn 1886, Henri Moissan's discovery of fluorine gas was announced at the Paris Academy of Science, two days after his first successful experiment to isolate the element, which he tested with silicon to find it burst into flame. “One can indeed make various hypotheses on the nature of the liberated gas; the simplest would be that we are in the presence of fluorine, but it would be possible, of course, that it might be a perfluoride of hydrogen, or even a mixture of hydrofluoric acid and ozone sufficiently active to explain such vigorous action as this gas exerts on crystalline silicon.” This conservative announcement was read to the Academy by Debray, for Moissan was not then a member. The president appointed a committee to check the discovery.* |
