Researchers see Kelvin wave on quantum 'tornado' for first time

A spinning tornado of very cold liquid helium obeys the laws of quantum mechanics. Sometimes, two quantum tornadoes flex into curved lines, cross over and form an X, swap ends, and then retract—a process called reconnection. ...

Can fluid dynamics offer insights into quantum mechanics?

In the first decades of the 20th century, physicists hotly debated how to make sense of the strange phenomena of quantum mechanics, such as the tendency of subatomic particles to behave like both particles and waves. One ...
