## PoSWW 37: Squaring the Circles

This one comes courtesy of Mystery Fred. The diagram above is for a Circle Gaps Brainteaser, and appeared online last week as part of Double Helix, CSIRO‘s science magazine for kids. The text for the brainteaser (as if it matters) is as follows:

What is the area of the orange star in the centre? The blue circles each have an area of 3 square centimetres, and the big square has sides that are 4 centimetres long.

A comment on the post makes it clear that the choices of sidelength and area were purposefully made.

## RatS 23: David Karoly – CSIRO and the Suppression of Science

So much crap, so little time. We’re desperately trying to get to the Australian Curriculum. Courtesy of the Evil Mathologre, however, we have about 2000 essays to grade. And, due to “mustÂ  be done” renovations, The Boss is demanding that the massive Everything in our garage be moved two meters to the left. (We suggested it’d just be easier to move the garage two meters to the right, but The Boss didn’t buy it.) Before all that, however, there are a couple posts that really need to be done, including this one, on CSIRO.
