Here follows the opening paragraph of an article entitled “Quantum Brinkmanship” by George Musser printed in the December 2008 edition of Scientific American. Just to demonstrate what you already knew: science is weirder than you imagined.

A good working definition of quantum mechanics is that things are the exact opposite of what you thought they were. Empty space is full, particles are waves, and cats can be both alive and dead at the same time. Recently a group of physicists studied another quantum head spinner. You might innocently think that when a particle rolls across a tabletop and reaches the edge, it will fall off. Sorry. In fact, a quantum particle under the right conditions stays on the table and rolls back.
