Quantum gas goes below absolute zero

Thanks to Phil Krause for suggesting this article. It may sound less likely than hell freezing over, but physicists have created an atomic gas with a sub-absolute-zero temperature for the first time1. Their technique opens the door to generating negative-Kelvin … Continue reading

The Triple Point

This video shows a liquid both boiling and freezing at the same time! Due to a drop in pressure, the mixture decreases in temperature. But the pressure drop also lowers the boiling point so the liquid both freezes and boils at the … Continue reading

Watch Water Boil And Freeze At The Same Time

Thanks to Tom Robb for suggesting this post. We think of freezing and boiling as opposites, things that happen at very different temperatures. However, under conditions of low air pressure the two can occur together, as we see in this … Continue reading

New surface treatment stops scale buildup

Scale, as these deposits are known, causes inefficiencies, downtime, and maintenance issues. In the oil and gas industry, scale has sometimes led to the complete shutdown, at least temporarily, of operating wells. So addressing this problem could have a big … Continue reading
