There’s a lot we don’t understand about quantum systems. But over the past century, physicists have found ways to exploit the many oddities of quantum mechanics to their liking—including a new ...

In new research published in Physical Review X, scientists have designed quantum control protocols that generate processes more consistent with time flowing backward than forward. The ...

If a cup of water spills on the floor, the water can’t unspill—that is, it’s inconceivable that each water molecule would exactly reverse its course to slip back into the cup. To do so would be to ...

(via Big Think) Dr. Robert Hazen, staff scientist at the Earth and Planets Laboratory of Carnegie Science in Washington, DC, thinks that a single arrow of time may be too limiting. A second arrow, ...
