Squares “A” and “B” in the photo above are the exact same color. Yet, if you still trust your eyes more than those words, there are a few simple tests and scientific principles that will help you realize that your eyes are lying to you.
Long before Indiana Jones inspired countless kids to study Egyptology, and before King Tut’s tomb was opened, travelers, researchers, and adventurers had had been travelling to Egypt to see the pyramids. But…
The Peacekeeper missile is anything but peaceful.
These eight lights beaming down on the Marshal Islands like a scene from War of the Worlds is not a sight you’d ever want to see in person.

It’s virtually impossible to imagine what the world would look like today without the computer. Though you might not think it, everything from the food we eat to the football helmets we wear to the rockets we send into space needed a computer’s help in some way. Needless to say, history’s very first computer, the Electronic Numerical Integrator And Computer (ENIAC), is on a very short list of the most important inventions humans have ever made.
The sound of 2,000 marbles has never been so euphoric.
Martin Molin — from the Swedish musical act Wintergatan — debuted his Marble Music Machine on YouTube last week. Since then, the world has gained a new respect for the old tradition of the humble hand-cranked wooden music box.

A complex series of shoots, levers, and pulleys lift and drop each marble with the precision and consistency of a well organized assembly line. The marbles then get back in position, waiting in line for their next opportunity to once again pass the checkpoints and strike a note. Vibraphone bars, the strings of a bass guitar, and various percussion instruments are hit in time by the marbles with the turn of each gear.
