Quantum mechanics for dummies

Clips from a BBC documentary explaining the arguments from the 1920’s until now as to whether electrons are particles, waves or both.

It outlines Einstein’s distaste at Heisenberg’s uncertainty principle and is a good starting point in realising that the universe is far, far stranger than can be imagined.

Quantum Mechanics for Dummies – Electrons Are Weird

Werner Heisenberg was a German theoretical physicist. He made contributions to quantum mechanics, nuclear physics, quantum field theory, and particle physics. Heisenberg, along with Max Born and Pascual Jordan, set forth the matrix formulation of quantum mechanics in 1926. Heisenberg was awarded the 1932 Nobel Prize in Physics. (Source: Wikipedia)

Einstein’s Intelligence Quiz: Who owns the fish?

Yong Liang sent me this. Pretty interesting but I am lazy to solve and I peeped at the answer. Opps.

Einstein’s Intelligence Quiz

Einstein wrote this quiz last century. He said that 98% of the people in the world cannot solve the quiz.

There are 5 houses in 5 different colors. In each house lives a person with a different nationality. These 5 owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet. No owners have the same pet, smoke the same brand of cigar or drink the same drink.
