Engineering: Featured Facts
Infrared Headphones
Engineering / Breakthroughs

Infrared headphones use infrared light to carry an information signal from a transmitter to a receiver. Sounds simple enough, but the actual process is very complicated. The human ear gathers sound as continue reading this fact

Alloys
Engineering / Materials

Brass is an important alloy. Water is a clear colorless liquid. So is methanol. If one were to take a quantity of methanol and pour it into some water, the result is also a clear colorless liquid. But this one is something new; a continue reading this fact

How We Use Crystals To Tell Time
Engineering / Breakthroughs

Quartz crystal mechanisms, common since the 1930s and 1940s, can keep a watch accurate to within a couple of seconds a month, or one part in a million. Quartz clock operation is based on the piezoelectric property of quartz crystals. If you apply an electric field to the crystal, it changes its shape, and if you squeeze it or bend it, it generates an continue reading this fact
