From SciAm guest blogger Kyle Hill: The Earth is flat. A full moon leads to more crime. Humans were created less than 10,000 years ago. If you made your way through even the most general of science educations, the above statements should strike you as suspect. Having a Copernican worldview challenged by such a statement,…
A “punk-sized” dinosaur with porcupine-like bristles featured some flashy stabbing self-sharpening fangs – although it likely only had a taste for plants. The newly identified dinosaur, named Pegomastax africanus, or “thick jaw from Africa,” was a mere two feet long and weighed less than a modern housecat in the flesh. Its remains were chipped out…
Adam Steltzner is a rocker-turned-NASA engineer who helped take the country’s cool new Curiosity rover to the surface of Mars. “I’m so thankful to Clara Ma for suggesting the name ‘Curiosity.’ It embodies a fundamental attribute that defines us as humans,” Steltzner begins, when asked to explain why Curiosity matters. “Why do we explore? It’s…
On November 8, 1800, fire ravaged the federal War Office, in Washington. The agency’s files went up in smoke, leaving a gaping hole in the nation’s historical record. “The most important window into the early republic had basically been boarded up,” says Christopher H. Hamner, a military historian at George Mason University. Not anymore. Through…
Sometimes, history really does seem to repeat itself. For the past 15 years, Peter Turchin, who studies population dynamics at the University of Connecticut in Storrs, has been taking the mathematical techniques that once allowed him to track predator–prey cycles in forest ecosystems, and applying them to human history. He has analyzed historical records on…
Eighth-century jump in carbon-14 levels in trees could be explained by “red crucifix” supernova.
It’s called the transit of Venus. The planet will appear as little dark circle on the sun as it zips between us and that big yellow ball. About every 120 years or so, transits of Venus come in clusters – two in eight years. The last one was in 2004, and we won’t see another…
The United States is at risk of ceding its leadership in science, a number of physicists said, though there was less of a consensus on a clear solution to the problem. Five physicists shared their worries about America’s scientific future during a panel discussion at the April 2012 meeting of the American Physics Society, agreeing…
The largest-ever gathering of Big History scholars, scientists, professors, teachers and graduate students will converge on Grand Rapids, Michigan, August 2-5, 2012 as the International Big History Association holds its inaugural conference.
Considered to be one of the greatest scientists of all time, Sir Isaac Newton was also an influential theologian who applied a scientific approach to the study of scripture, Hebrew and Jewish mysticism. Now Israel’s national library has digitized Newton’s theological collection — some 7,500 pages in his own handwriting — and put it online….
