Einstein & Relativity

Bohr v. Einstein

Bohr believed in "Quantum Physics" which was based on probability. Einstein wanted consistency not probability.

What device was created from E=mc^2

Nuclear bomb in 1940s. Einstein was furious

Explain how stars shine

Proved stars weren't burning oxygen like a fuel, actually nuclear fusion allowed starts to produce energy/light

Einsteins First Paper

1905-The Photo Electric Effect (won 1921 Nobel Prize in physics) -Proved in experiment that light behaved like a particle called a photon -"Dual Nature"

Died?

1955

Where did Einstein go to college? What did he become instead?

-Attended Polytechnic University in Switzerland to be physics teacher -became Swiss patent clerk. It was intellectually stimulating & allowed free time

Einsteins Fourth Paper

-Confirmed the Molecular Theory -Brownian Motion

In 1915 Einstein published? predictions?

-General Theory of Relativity which explained the Theory of Gravity -Einstein viewed gravity as a 4D idea which warped space time instead of just a force like newton 1) massive bodies slowed down time 2)possibilities of black holes 3)gravity waves

What object did Einstein's father show him at a very young age which impressed him greatly? How is this like Isaac Newton?

-Magnetic Compass; he loved magnetism -like newtons uncle who gave him a pocket watch.

Einsteins Second Paper Lists the 4 basic Results

-The Special Theory of Relativity -"the Invariance Theory" because it was invariant (speed of light doesn't change) 1)Cosmic Speed limit-no object can go faster than speed of light 2) Time Dilation-time slows as reach speed of light 3) length deduction 4) mass increase

In what town and country was Albert Einstein born? Where did he grow up? And what public school did he attend?

-Ulm Germany then moved to munich -Public School called Luitpold Gymnasium

New Theory announced by Einstein in 1929?

-Unified Field Theory -tried to figure out how the 4 fundamental forces started as one but broke up into speared forces. -could combine electromagnetic, strong nuclear, & weak nuclear. -never could connect gravity

Describe the 2 Postulates of the Special Theory of Relativity

1) The laws of physics are the same in all inertial frames of reference 2) the speed of light in empty space is constant independent of the speed of the source of light or of the observer.

Einsteins Third Paper

1905- E=mc^2 Energy=matter
