In a First, an ‘Atomic Fountain’ Has Measured the Curvature of Spacetime

by

In 1797, English scientist Henry Cavendish measured the strength of gravity with a contraption made of lead spheres, wooden rods and wire. In the 21st century, scientists are doing something very similar with rather more sophisticated tools: atoms. Gravity might be an early subject in introductory physics classes, but that doesn’t mean scientists aren’t still trying to … Read more

Scorching Siberian Heatwave Confirmed as Hottest Arctic Temperature Ever Recorded

by

The UN on Tuesday officially recognized the 38 degrees Celsius measured in Siberia last year as a new record high for the Arctic, sounding “alarm bells” over climate change. The sweltering heat – equivalent to 100.4 degrees Fahrenheit– was seen on June 20, 2020 in the Russian town of Verkhoyansk, marking the highest temperature ever … Read more
