Today’s Google Doodle Celebrates S.P.L. Sørensen by Testing Your pH Scale Knowledge

Today’s Google Doodle gave me a few horrifying flashbacks to middle school pop quizzes (I was truly, truly awful in chemistry), but the adorable tribute to SPL Sørensen’s pH scale is more delightful than anything else. If you guess them all right, the objects do a cute thing to spell the world Google too! It’s exactly the kind of educational game you’d play in school that tricks you into learning with its cuteness.

The Doodle highlights the work of Sørensen’s Danish scientist Søren Peder Lauritz Sørensen, who introduced the method for testing the acidity of a substance.

There are two other Doodles out today as well: Nepal Republic Day (viewable in Nepal) and Alfonsina Storni’s 126th Birthday (viewable in Peru, Argentina, and Chile). The Storni Doodle is especially beautiful, displaying her poem La Loba (The She-Wolf, 1916) which “recounts her experience raising a son as a single mother while defying patriarchal norms of time.” I would have loved to see the feminist, poet, writer, journalist, and icon get more reach with her Doodle, but you can’t win ’em all. I’ll leave you with her poem, “You Want Me White“.

What did you think of today’s Doodles? Do you remember your pH scales?
