Measurements in physics are funny things. You’d hope that attempts to quantify some of the fundamental properties of the Universe would follow a simple pattern: they’d start with large error bars, but, over time, measuring technology improves and the error bars shrink. Ideally, the value would then remain nicely within the previous error.

MIT, Harvard, and LBNL physicists have discovered a new quantum electronic material, the “kagome metal,” whose atomic structure resembles a Japanese basketweaving pattern and exhibits exotic, quantum behavior.

You probably scratched your head last year if you read about time crystals, likely 2017’s most esoteric, widely covered popular science story. Even if you understood how they worked, you might not have known what use they could have. Time crystals, systems of atoms that maintain a periodic ticking behavior in the presence of an added electromagnetic pulse, have now piqued the interest of one well-funded government agency: the Department of Defense.
