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.
In a new interview with the Journal of the American Medical Association above, Anthony Fauci, National Institute of Allergy and Infectious Diseases (NAID), said he expects the US will have 100 million doses of a COVID-19 vaccine before the end of the year. “Then, by the beginning of 2021, we hope to have a couple […]
Just for kicks, Paul Rule, 66, participated in a study launched by the Cambridge Natural History Society that enlisted citizen scientists and nature-lovers to help deepen knowledge of the flora and fauna in Cambridge, England. Rule recorded nearly 600 different animal species in his “ordinary” city garden, including an elephant moth like the one seen […]
Astronaut David Scott re-created, in 1971 during the Apollo 15 mission, Galileo’s “falling bodies” experiment by dropping a hammer and feather on the moon at the same time. Simply, both fell at the same rate because there was no air resistance. screengrab via Wonders of Physics/YouTube (Digg)
The world is holding its collective breath. As states begin cautiously reopening, no one is sure exactly what to expect. But one thing is clear: most Americans are worried about their bank accounts. By the end of March, the average American household was spending 40 percent less on their credit cards than they were one […]
Over 25 years, eBay has carved out its space as the commerce hub of choice online. With 182 million users worldwide, that works out to about 35 percent of all US mobile users who shop those eBay storefronts. But did you know there are usually around 1.3 billion — with a B — active for-sale […]
Software apps are a dime a dozen. Well, if you’re going by their actual monetary cost, maybe not really. But considering how useless some poorly conceived, poorly executed apps are at doing the job you actually downloaded them to accomplish, it isn’t a stretch to think that many apps aren’t even worth a free download.
