Today’s animated Google Doodle celebrates Heinrich Rudolf Hertz, the German physicist on what would have been his 155th birthday. His experiments with electromagnetic waves led to the creation of the wireless telegraph and the radio. Hertz showed that electricity can be transmitted via electromagnetic waves.
You may wonder why his last name sounds so familiar. That is because Hertz’s name later became the term used for radio and electrical frequencies. Think of hertz (Hz), kilohertz (kHz) and megahertz (MHz). In 1933, long after his death, the Hertz officially became part of the metric system.
Google’s animated doodle is an homage to Hertz’s contributions to physics. The wavy animation, which is in Google’s trademark colors of red, blue, yellow and green, is in recognition of the German physicist’s work with electromagnetic waves. Very fitting!
