1905
As the second year of the massive Russo-Japanese War begins, more than 100,000 die in the largest world battles of that era, and the war chaos leads to the 1905 Russian Revolution against Nicholas II of Russia and the start of Revolution in the Kingdom of Poland. Canada and the U.S. expand west, with the Alberta and Saskatchewan provinces and the founding of Las Vegas. 1905 is also the year in which Albert Einstein, at this time resident in Bern, publishes his four Annus Mirabilis papers in Annalen der Physik , laying the foundations for more than a century's study of theoretical physics.
