Coins Swiss

Four rare-earth elements (yttrium, ytterbium, erbium, and terbium) have been named in honor of this village. A year later, the Swedish chemist Lars Fredrik Nilson (1840-1899), discovered another element in "erbia" and he named it scandium (Sc) in honor of Scandinavia. At the same time, Nilson s compatriot, the geologist and chemist Per Theodor Cleve (1840-1905) succeeded in resolving the "erbia" earths yet another step further, when he separated it into three components erbium, "holmium" (Flo) and thulium (Tm). The name "holmium" refers to Stockholm (Qeve s native city) and had been independently discovered by the Swiss chemists Marc Dela-fontame (1838-1911) and Jacques-Louis Soret (1827-1890), who had coined the metal element X on the basis of its absorption spectrum. 

The problem can be illustrated with respect to a simple game of chance which I call coins and which comes in two versions. In each version a fair coin is tossed three times and a Swiss franc is paid for each toss. A reward is paid if and only if all three tosses are successful. In the first version, the reward is Sfr 25.00 and in the second Sfr 20.00. However, for the first game the three francs must be paid up front. In the second they are only paid to see each toss and the player can stop any time he or she likes and start another game. Which of the two games is more valuable. ...
