First, a fun announcement: The second Bedtime Math book is coming, with all-new wacky math…and it’s kicking off with a big party for you! Bedtime Math 2: This Time It’s Personal launches March 11, and to celebrate we’re throwing a nationwide Glow-in-the-Dark Geometry Party that week at bookstores across the U.S. Kids will build giant geometric shapes out of glowsticks, then flick off the lights to see them shine. Over 130 stores in 41 states are taking part, and New York-area parties will have Laura there in person to read to the kids and sign books. Check the list here to find a party near you!

With that, let’s have a sneak preview from the book.

Underwear is that strange piece of clothing where no one sees it on us, but we still care what it looks like. We don’t want to wear underwear that’s goofy-shaped, or full of holes, or decorated with a cartoon character we haven’t liked in 3 years. That’s why things turn desperate when the laundry hasn’t been washed in a few days and we run out of underwear. How many pairs do we need to get through the week — and if we run out, how many people are we willing to tell?

Happy Birthday, iTunes!

Today is the 10th birthday of iTunes, the online store that lets you buy songs, movies, apps for your smartphone, videos…all kinds of stuff that you can enjoy on your phone or computer. Before iTunes, the only way we old-timers could buy songs was on something you could hold in your hand, like a CD, a tape cassette or a vinyl record. Or you could get songs electronically from various illegal websites, which was exciting but felt icky. So the idea that you could get onto your computer, buy any song you wanted (legally), and get it within seconds was mindblowing. iTunes opened with just 200,000 songs on it, all priced at 99 cents, and within just one week they had 1 million song downloads. As of today, iTunes has sold over 15 billion song downloads from a collection of 26 million different songs. Let’s just say, it takes far more than one person to listen to it all.

Hand Me the Phone

On this day in 1876, Alexander Graham Bell finally got his invention working: the telephone.  It worked nothing like our phones today: the very first phones were sold in pairs, where each phone could call only that one other phone (you had to pick that other person carefully).  Then came the “switchboard,” which let you call any other phone, but the “operator,” a phone company person in the middle of town, had to plug in wires to connect your call for you.  Now we can call anyone anywhere on our own within seconds, and through the air.  But that first phone, that first time talking to someone through a wire, must have looked like magic.
