generate, and where these ultra-high-energies come from is a big question. Perhaps they come from outside the Galaxy, from active galactic nuclei, quasars or gamma ray bursts. Or perhaps they're the signature of some exotic new physics: superstrings, exotic dark matter, strongly- 9 interactingneutrinos, or topological defects in the very structure of the universe. Questions like these tie cosmic-ray astrophysics to basic particle physics and the fundamental nature of the universe. 10

petroleum demand and declining U.S. production 1906 Special theory of relativity written. Albert Einstein created a new era of physics when he unified mass, energy, magnetism, electricity, and light. One of the most significant events, if not the very most significant event, of the 20th century was Einstein's writing the formula of E=mc2: energy = mass times the square of the speed of light. This led to nuclear medicine - and a much longer life span, astrophysics, and commercial nuclear electric power 1942 Scientists produced nuclear energy in a sustained nuclear reaction. 1957 The first commercial nuclear power plant began operating. 1995 Nuclear power contributed about 20 percent of the nation's electricity. 5.1 Signficant Events in the History of Energy Uses 1781 The stagecoach was the worldwide standard for passenger travel. 1800 Transportation as we know today was almost non-existent. Railroads covered far less territory
