In 2001, Cramer wrote a science-based column for Analog Science Fiction and Fact magazine describing the likely sound of the Big Bang based on cosmic microwave background radiation observations taken from balloon experiments and satellites. Big Bang's sound recreated in HD I first read about the...
SpaceX is notable for reusable rockets, satellites that provide internet connectivity on Earth, and space tourism. Falcon 9 rocket made its first launch in 2012. And the spaceship was uncrewed, with a thousand pounds of supplies for astronauts in the International Space Station. ...
A proof-of-concept study finds that it is possible to identify an individual's ancestral background based on his or her fingerprint characteristics – a discovery with significant applications for law enforcement and anthropological research.
