These structures allow roads to cross safely without those pesky traffic lights, stop signs, or roundabouts. An overpass on the New York Thruway – image by Jojalozzo Utilizing vertical space for road travel is good for both […]
Roy G. Biv Many students learn the mnemonic Roy G. Biv to recall the visible colors: Red, Orange, Yellow, Green, Blue, Indigo, Violet.

Stick Your Head in a Particle Accelerator The Large Hadron Collider, operated by CERN, the famed European Organization for Nuclear Research, is the world’s biggest particle accelerator. Also known as “atom smashers” or “supercolliders,” accelerators are massive machines that use electromagnetic fields to launch particles at extraordinarily high speeds, usually near the speed of light. Particle
