### Relativity CW #1

Mr. Bruce

This lists terms from both special and general relativity theory, people in the film "Einstein's Big Idea" (a great movie BTW), as well as E=mc2 principles.

3.In general relativity, Einstein developed a tensor calculus set of 10 equations which are now referred to as his ______ equations.
4.In Einstein's general relativity paper he accounted for the error in this planet's orbit as calculated by Newton's universal gravity equation.
7.This man invited Einstein to see the red shift of receding galaxies which validated that the universe was expanding.
9.This Jewish woman later received a Noble Prize for her work in describing how Otto Hahn had split the atom.
10.The ___ shift is evidence that the universe is expanding.
11.This woman challenged Newton's published idea and supported Leibniz, showing that energy depended upon the square of the velocity. She was perhaps 150 years ahead of her time.

19.In 1905, Einstein published his ______ relativity theory, in which he ignored acceleration and the effect of gravity on motion.
21.Albert ______ did an experiment in California that measured the speed of light 20x more accurately than had been done before in 1878.
30.The description that Einstein gave for this phenomenon, when light shining on a metal caused electrons to flow.
31.Length ______ is the special relativity effect of lengths of objects in a moving frame shortening from the perspective of a stationary frame of reference.
32.This concept was first proposed by Galileo concerning motion, was supported and developed by Newton and appended to by Einstein to include time.
33.This principle says that whatever equations Einstein developed in his special and general relativity theories needed to work when speeds or gravitational fields were normal, everyday sizes.

1.The shortest distance between two points near a large mass is not a straight line. This is referred to as a ______.
2.______ was a Roman Catholic priest who was also a physicist. He proposed what was later referred to as the "Big Bang" theory.
