Quantum Mechanic is one of the most important discovery since the end of 19th century. It's about a way for scientists to view our physical world not in a macroscopic scale, but in a microscopic scope. Throughout years of discussion, experiment and argument, mystery about quantum mechanic seems to remain.

"Double slits" is probably the most famous experiment of quantum mechanic. In this experiement, it shows that the tiny electron behaves not only like a tiny marble, but also like a wave, and this result turns out to be astonishing and confusing for scientists in 1920s, but even until now, no one can actually come up with an explanation.

From then on, the classic physics traditions since Newton can never reclaim that they've discovered all the possible physic phenomenon. Quantum mechanic had already proved that the world we live is far beyond our imagination.
