Have you peeped Google today? It’s all about S. P. L. Sørensen, a famed Danish chemist.
The search engine site, which sometimes uses its homepage to honor prominent figures, is highlighting the influencer, who introduced the concept of the pH scale.
Born in Denmark in 1868, the scientist gravitated towards medicine at a young age. However, after enrolling at the University of Copenhagen, he shifted gears to chemistry.
In the early 1900s, he rose to fame as the head of the Carlsberg Laboratory. While there, he developed the pH scale. He created the method of measuring acidity and alkalinity while studying ion concentrations.
Introduced in 1909, the system is now universally used for water treatment, medicine and other forms of science. It is also taught in classrooms across the globe.
But Sørensen didn’t stop there. He continued to conduct a variety of other experiments, working at the Carlsberg Laboratory for 37 years. His second wife Margrethe Høyrup Sørensen was one of his closest collaborators.
In 1939, he died at the age of 71, but his contributions to science are still celebrated today by many, including Google.
It’s paying tribute with an doodle, which illustrates the scientist and his pH scale. Viewers who choose to interact must determine where everyday items, such as tomatoes, lemons, eggs and broccoli, are acidic or alkaline.
