1884
• Einstein saw a wonder when he was four or five years old: a magnetic compass.
• The needle's northward swing, guided by an invisible force, impressed him.
• The compass convinced him that there had to be "something behind things, something deeply hidden."

Albert - as a Student
• Einstein knew, from then on, that he wanted to teach math and Science at a University someday.
• The problem was, he wasn’t a very good test-taker and could not get a job at a University because of it.
• Rumor has it that he had even failed a Math test, but some people question that because of the way grades were assigned back then.

1905
• Albert Einstein develops his Special Theory of Relativity.
• He did this while working as a Patent Clerk in Germany.
• He wasn’t really even a scientist at the time.

Einstein’s Special Theory of Relativity
• Relative to who is watching, space and time are transformed near the speed of light: distances appear to stretch; and clocks tick more slowly

Einstein’s Special Theory of Relativity
• Einstein’s theory meant that Newton’s Laws needed to be modified.
• Space and time are not absolute - and the universe we live in is not actually the one Newton "discovered.

Einstein in 1905
• Einstein uses the idea that light exists as tiny packets, or particles, that we now call photons.
• • His work anchors the
most shocking idea in twentieth century science: we live in a universe built out of tiny bits of energy and matter.

Einstein in 1905
• Next, in April and May, Einstein publishes two papers.
• In one he invents a new method of counting and determining the size of the atoms or molecules in a given space.
• In the other he explains the phenomenon of Brownian motion.
• The net result is a proof that atoms actually exist - still an issue at that time.

Einstein in 1905
• And then, in June, Einstein completes special relativity - which adds a twist to the story: special relativity sees light as particles and a continuous field of waves.

Einstein IN 1905
• And of course, Einstein isn't finished. Later in 1905 comes the most famous relationship in physics: e=mc2.
• The energy content of a body is equal to the mass of the body times the speed of light squared.
• At first, even Einstein does not understand the full implications of his formula. 2mce

1910-1913• In 1910, Einstein
addressed a basic question: "Why is the sky blue?" He approached the problem by looking at the effect of the scattering of light by individual molecules in the atmosphere.
• In 1913, Einstein begins work on his new Theory of Gravity.
