This result is now known as Gauss' Eureka theorem and is a special case of what later became known as the Fermat polygonal number theorem.

The 1848 Gold Rush and How It All Began
Not A Walk in The Park
- As easy as it sounds today traveling to California, in the middle of the 19th century it was not a walk in the park. Some traveled by sea which took several months. The most famous land route was the California Trail, a route of 3,200km across the western half of the United States. Either way, the travelers had to face fever, cholera, and often death. Still, most of them made it to San …
The 49-ers
- The big amount of 49-ers (as the gold seekers were called) caused many structural and political problems. First of all, the new citizens had to be supplied with food and it sometimes took too long for the merchant ships to arrive. Also many disagreements between Americans and foreigners began and resulted in cruel attacks from American prospectors against mainly the M…
The Life in Camps
- After a short time, the gold that could basically just be collected from the ground was gone and the 49-ers had to come up with new techniques that were more of hard work and also very pricy so that many had to receive loans from the bank or were forced to work together. These circumstances affected the life in the camps the gold diggers were living in were described by M…
Modest Profit
- The overall profit of the miners was rather modest in contrast to the many merchants settling in the new cities, one of them was the famous Levi Strauss selling denim overalls. The California Gold-Rush indeed stimulated the economy, let the cities grow fast and was the reason for several technical inventions as well as the construction of schools, roads and train routes.
The Effect on California
- The uncontrolled immigration of people also caused great problems: San Francisco burned six times between 1849 and 1851. The hygienic conditions were catastrophic, fleas and rats spread. A cholera epidemic broke out in the winter of 1851. At the beginning of the Spanish Mission, the indigenous population of California was estimated at around 310,000. At the end of the Mexica…
