First, a really fun announcement: Bedtime Math is throwing a giant Pajama Party at the new Museum of Mathematics in New York!  If you live in the NYC area or will be visiting, on Saturday Feb. 2 kids from ages 3-8 can come to MoMath in their PJs and play home-baked Bedtime Math games.  You all get first dibs before this gets announced publicly, so click here to get the details and register!

And as long as we’re talking about math, it’s a great time to ponder the number 2013, our very cool new year.  It’s the first year in a long time where all four digits are different – more on that below. Also, because the number 13 is prime – meaning it’s divisible only by itself and 1, and can’t be split into equal-sized groups – 2013 looks kind of yucky and prime also, but it actually isn’t.  While the number 13 is considered unlucky by a lot of people, we’re thinking 2013 is going to be a good year.

Double – or Triple – the Fun

Yesterday at Alexandra Palace in London, a guy named Phil “The Power” Taylor won the world professional dart championship for the 16th time.  Whoa!  And throwing darts is no easy sport: you aren’t just aiming for the middle of the dartboard the whole time.  As you see in this picture, each wedge of the board has a number, which equals the points you score if you throw your dart there – except for the skinny green and red rings, which double or triple those points.  Even the bullseye has multiple parts: its outer ring is worth 25 points, but the very center is worth double that (50).  To make matters worse, to win the championship you have to score exactly 501 points, and your final throw has to land on the double ring or the double bulls-eye.  So darts aren’t just a matter of good aim – you have to do the math right, too.

It’s a Zoo Out There

July may be National Ice Cream Month, but this week is National Zoo Keeper Week.  What a great job: you get to hang out at the zoo every day, pet all those furry animals, and feed them without even having to stand in line.  Of course, the job also has its dangers, like possibly losing your hand when you try to feed the sharks.  If you imagine a typical day for a zookeeper, you see that the excitement could add up fast.
