Google celebrates Hans Christian Ørsted's Birthday

Hans Christian ØrstedOne of the amusing things about Google is that it commemorates special occasions by changing its logo to match the event that is celebrated.

Today, Google celebrates Hans Christian Ørsted's birthday by changing the standard Google logo into a Google logo with an aluminum wire text. Clicking on the logo will automatically run a search query using the keyword "Hans Christian Ørsted."

Who is Hans Christian Ørsted by the way? And why is he special? After running the auto keyword by clicking on the Google logo, we were directed to Wikipedia, and this is what we found.

Hans Christian Ørsted (14 August 1777 – 9 March 1851) was a Danish physicist and chemist who is best known for discovering that electric currents can create magnetic fields, which is an important part of Electromagnetism. He shaped post-Kantian philosophy and advances in science throughout the late nineteenth century. He was also the first modern thinker to explicitly describe and name the thought experiment.

You may also wonder why the Google logo is written in Aluminum texts. Here's why..

In 1825, Ørsted made a significant contribution to chemistry by producing aluminium for the first time. While an aluminium-iron alloy had previously been developed by British scientist and inventor Humphry Davy, Ørsted was the first to isolate the element via a reduction of aluminium chloride.
