This Blue Laser Just Solved a 150-Year Physics Mystery
For over a century, physicists knew a strange magnetic signal should exist in everyday metals like copper and gold, but they couldn’t see it. Now, using only a blue laser and a clever tweak to a classic technique, scientists have detected this elusive phenomenon known as the optical Hall effect. This breakthrough not only reveals [...]
