Today’s Tough Trivia question: Scales: fish wear them for protection, humans step on them to fret about their diets. We love to measure, rank, and grade things. Your question for today: what do we measure with the following scales: Fujita, Mohs, Richter, Scoville. Bonus points if you know what measures on those scales are for the least intense, and for the most.

Yesterday’s question was: More so than most artists, Spanish artist Pablo Picasso’s (1881–1973) paintings are frequently categorized by period, during which the paintings bear striking similarities. How many of those periods can you name? Bonus point if you can name them in order.
And the answer is:
Blue Period: 1901–04
Rose Period: 1904–06
African-influenced Period: 1907–09
Analytic Cubism: 1909–12
Synthetic Cubism: 1912–19
For the next decade, most of his work is considered necoclassical and Surreal. His later work amalgamated his earlier styles.
