Demonstrate one of the weirdest quantum effects in your home using a laser pointer, some tinfoil, a piece of wire, and a $7 polarizer. The device, called a quantum eraser, operates in a way very similar to the famously mind-blowing double slit experiment that was voted the most beautiful experiment in physics.
e=mc^2*100 It has been a hundred years since the date that Einstein's famous equation was first published, the last of his four annus mirabilis papers of 1905. In celebration, you can hear Einstein explain his formula (or listen to any of 10 other famous physicists do the same), or read an interesting site in celebration of his life and works, or, if physics isn't your thing, peruse his views on religion, or his exchange with Freud about war, or take a look at hundreds of his original manuscripts.
