Three years ago astrophysicist Tom Collett set out to test a theory. Not just any theory, but one that sets scientists’ expectations for how the universe operates at large: Einstein’s general relativity. First published in 1915, the theory mathematically describes how gravity emerges from the fundamental geometry of space and time, or spacetime, as…
In the early hours of 5 February 1971, Don Eyles had a big problem: Apollo 14 astronauts Alan Shepard and Edgar Mitchell were orbiting the moon, preparing to land, but it looked like they were going to have to come home without putting so much as a single footprint on the surface.
Landing Small exploratory spacecraft on asteroids and comets is an incredible engineering feat. Some of these “rocks” are only a few miles wide. Talk about finding a needle in a haystack… – Jeff By Ryan F. Mandelbaum The Rosetta mission’s Philae lander descended toward the two-and-a-half-mile-wide comet at a human’s walking pace. For…
The time may be coming when computers and other systems are made not from individually packaged chips attached to a printed circuit board but from bare ICs interconnected on a larger slice of silicon. Researchers have been developing this concept called “chiplets” with the idea that it will let data move faster and freer…
Researchers at Alphabet’s DeepMind today described a method that they say can construct a three-dimensional layout from just a handful of two-dimensional snapshots. So far the method, based on deep neural networks, has been confined to virtual environments, they write in Science magazine.
