Happy birthday to two of my favorite entertainers, John Barrowman (b. 1967) and Keren Peles (b. 1979).

(Yes, there are other famous people whose birthday is today, but these are the two whose artistic output I have enjoyed over the past year.)

According to today's NYT, part of the proposed national curriculum states that third graders should "[u]nderstand that rectangular regions can be tiled with squares in rows and columns, or decomposed into such arrays." (K-12 Math Standards, p. 21)

But that's not true. By definition, if the sides of a rectangle are in an irrational proportion, it cannot be decomposed into an array of squares.
