The last week of January often marks the coldest week of the year, at least for the northern half of our planet. We’ve been tilted away from the sun for weeks, we’ve had short days of sunlight, and in some places cloudy gray skies make matters worse. So it’s no surprise that many states have had their coldest temperature ever in late January or early February. When you see some of the records set over the decades, you might find that a bowl of ice cream at 3 degrees F could warm you up.
It’s pretty exciting to get on a roller coaster, tip over the top of a hill and plunge toward the ground at 30 miles an hour. But it’s even more alarming to do this in the dark. On this day in 1975, Disney Parks opened Space Mountain, the famous roller coaster at Disney World in Orlando, FL. The entire ride spirals around the inside of the mountain, dark except for sparkly stars and some pulsing lights, which do nothing to help you see where you’re going. So every twist, turn and plunge comes as a total surprise. Clearly lots of daredevils love this kind of thrill: over the decades hundreds of thousands of visitors have ridden Space Mountain, leading Disney to build four more of them around the world.
On this day in 1930, a certain cartoon character showed up in U.S. newspapers for the first time: Mickey Mouse. When Walt Disney and Ub Iwerks first drew this friendly rodent two years earlier, he probably had no idea that a mouse could become so popular. With his high voice, red shorts, and poofy yellow shoes that look impossible to walk in, Mickey is one of the world’s most famous cartoon characters. He was also the first cartoon character to get a star on the Hollywood Walk of Fame alongside real humans – after all, he wears clothes, too.
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.
As people in Alaska like to say, “If Texas doesn’t quit saying they’re the biggest state, we might just cut ourselves in half and make them third biggest.” Alaska may be the baby of the American family – it became the 49th state out of 50 on this day in 1959 – but it is by far the largest. There are only 18 countries bigger than Alaska, and it’s also bigger than the 22 smallest U.S. states combined. Thanks to having all that space, Alaska has lots of room for huge mountains, beautiful glaciers, and lots of cool animals, including 200,000 of the state animal, the moose. By comparison, there are only about 730,000 people – not surprising for a state with a record low temperature of negative 80 degrees. At the least, everyone has lots of space.
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.
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.
