Google Doodle Is Celebrating S.P.L. Sorensen, the Scientist Behind the pH Scale

Google (GOOGL, -1.49%) is celebrating a little-known but hugely influential scientist with the Google Doodle today.

The Danish scientist S.P.L. (Soren Peder Lauritz) Sorensen is the man who invented the pH scale (remember those pink and blue strips from your high school chemistry class?)

S.P. L. Sorensen developed the method of measuring acidity and alkalinity in 1909 while studying the effect of ion concentration on proteins. Today the method is hugely important for daily necessities like clean water and medicine.

Sorensen was born in Havrebjerg, Denmark 1868. He studied at the University of Copenhagen with the intention of studying medicine, but went on to have a career as a scientist. Sorensen was the head of the prestigious Carlsberg Laboratory in Copenhagen for 37 years, where he worked alongside his second wife, Margrethe Høyrup Sørensen. He worked in the lab until the year before his death at age 71.

With the interactive feature of today’s Google Doodle, you can learn where common foods fall on the scale.

Call of Duty WW2

Call of Duty WW2 Call of Duty : WWII pre-review Many of us are old enough to remember a time when the idea of a first-person shooter set during World War II seemed overdone to the point of parody. The first three Call of Duty releases took place during World War II, breaking from the tradition with 2007’s Call of Duty 4: Modern Warfare . Call of Duty: WWII , developer Sledghammer Games’ second full release in the franchise, brings us back to that historic conflict as the series begins to eat its own tail on modern hardware. Or maybe this could be seen as a sort of reboot. Call of Duty: WWII packs in the same ridiculous amount of things to do as past games in the series with a full single-player campaign, many options for multiplayer including the asymmetrical War game mode , the new Headquarters social hub and of cours...
