X-rays were first studied by a German scientist in 1895, and that’s the subject of the latest Google doodle.
Wilhelm Conrad Röntgen discovered them by accident while experimenting with vacuum tubes. In fact, X-rays are also known as Röntgen rays in some quarters.
Google’s doodle shows the company logo as an X-ray, with various bones inside the letters, and indeed other objects such as a key, and a rubber duck. We won’t ask what the logo gets up to in its spare time…
While the doodle looks like just a straightforward drawing this time, it is actually slightly animated, as it pulses with a radioactive glow around the letters if you look carefully.
Röntgen won the first Nobel Prize in Physics, awarded in 1901. A humble man, he apparently gave the reward money to his university.
