When a Flashing Light Shows More

Believe what you see? It might depend on your light source. Not all light sources provide our brains with the same information. Whip up this fascinating optical illusion to see for yourself! Credit: George Retseck

Do you have to see it to believe it? You might want to rethink your strategy. Scientists now know that what we perceive can be very different from what is really there. Our brains are quite clever in helping us interact with the world, but they can be fooled. Try this activity, and you will find out how!

On Second Thought
Our current standard unit of time, the second, is based on the cesium clock. But scientists are now planning to redefine it with optical atomic clocks, which have achieved far greater precision, as Alanna Mitchell reports for The New York Times. Optical clocks are sensitive to infinitesimal changes in their environment, even gravitational ones. In 2021 Katie McCormick wrote for Quanta about a clock that revealed gravity's changing influence on time across a 1-mm cloud of atoms.

Explaining the Higgs Mechanism
Symmetry dictates that the W-boson and other particles in the Standard Model should be massless. So why aren't they? Matt O'Dowd explains for PBS Space Time how the Higgs mechanism gives things mass. The key to the Higgs mechanism is that an underlying symmetry of the laws of nature can be "spontaneously" broken by the state of a system, as physicist David Kaplan explained in a 2015 video for Quanta.
