This is pioneering computer scientist and US Navy read admiral Grace Hopper (1906-1992) explaining the concept of a nanosecond. From the Computer History Museum:
(Hopper) held a B.S. in mathematics and physics from Vassar College (1928) and an M.S. (1930) and Ph.D in mathematics (1934) from Yale University.
Hopper began her career teaching at Vassar and taught there from 1931 to 1943, when she joined the u.s. Navy Reserve. Her first assignment was to work with Professor Howard Aiken of the Harvard Computation Laboratory on problems of military significance.
Hopper remained at Harvard until 1949, when she joined the Eckert-Mauchly Computer Corporation, led by the designers of the groundbreaking ENIAC computer system. There, she developed one of the world's first compilers and compiler-based programming languages. In 1959, Hopper played an important role in defining a new easy-to- use programming language. The result was COBOL, probably the most successful programming language for business applications in history.
Ant Lab's Adrian Smith (previously) writes, "No one had ever filmed how ants inject venom when they sting something. I study ants and I make videos, so I went to work on getting that footage. It involved filming something smaller than a human hair moving faster than the blink of an eye. But, I got […]

Above is a three-millimeter long maggot launching itself into the air for a distance of up to 36 times its body length. Researchers from Duke University and their colleagues studied how these larvae of gall midges leap between plants with the greatest of ease, even rivaling some jumping insects with legs. Their research could have […]
It’s a great time to be a maker. 3D printers are on store shelves for anyone to buy, and coder kits like Arduino and Raspberry Pi are letting kids as young as 9 or 10 dive into the Internet of Things. Here are a few examples of our favorite tech toys, all priced low enough […]

Let’s face it: People at the gym aren’t bragging about their headphones. If they were that great, they’d be listening to them instead of talking about them. So while we’re sure those new PowerBeats Pro earbuds are something special, why would you shell out $250 for a tiny pair of speakers when comparable ones are […]
