“Scarcity captures the mind,” write the authors, an economist and a psychologist...
A survey of more than 3,700 U.S. scientists from a range of fields finds that researchers are feeling the pinch (stats above).
U.S. federal spending on science has decreased sharply since 2010 in inflation-adjusted dollars (graph below).
Mathematicians have conjectured since Euclid’s time that there are infinite pairs of prime numbers separated from each other by 2. Despite the fact that primes are separated on average by bigger gaps as numbers increase, evidence suggests that primes continue to appear as “twin primes” (green triangles) no matter how high you go. The illustration above highlights prime numbers, counting from 1...
It’s finally official: Voyager 1 has become the first human-made object to enter interstellar space, mission scientists report September 12 in Science. On August 25, 2012, the scientists say, Voyager 1 exited a giant invisible bubble called the heliosphere that is inflated by a torrent of subatomic particles spewing from the sun. Now the probe is surrounded almost exclusively by particles...
