The Iditarod Trail Sled Dog Race is the most famous dog-sledding event, and is often called “The Last Great Race.” Just why is it called this? Read on to run through the numbers in this race, and find out what makes it so great!
When people think something is easy, they call it a “piece of cake.” We’re not sure making this car was easy, but it is a BIG piece of cake! This is the new fastest and longest-traveling edible vehicle on Earth. There are some non-cake parts in it: a metal frame like a bike, and rubber […]
When we hear a giant snowstorm is coming, we get really excited to play in the snow. But sometimes the storm decides to go another way and we don’t get any snow. Well, one grandpa decided to fix that problem for his granddaughter. Read on to see how he did this – and do the math in traveling snow!
Did you ever wonder what cars would say if they could talk? Chances are they’d ask a lot of questions that you’d be able to answer by doing some math. So read on to see what your car might say…and figure out how you’d answer it!
Wait, is that a llama running down the street?! That’s what happened in Newburyport, MA last Wednesday. Llamas are big, shaggy animals that normally live in South America. There are only about 40,000 of them in the US. But some people keep them as giant pets, and sometimes llamas break free. The one in this […]
When we drive on the road, we can’t all just go every which way. We have to stay on one side, and wait our turn where roads cross. Stop signs help, but really busy crossings need traffic lights. The traffic light, that cute red, yellow and green trio, was patented (made official as an invention) on this day in 1923. Actually, the very first electric traffic light was invented in 1912 by Lester Wire, a policeman in Utah fed up with all the traffic; you can imagine, after hundreds of years of slow horse-drawn carriages, what it was like to have this speedy, loud thing called a car suddenly show up. So Wire borrowed the idea of railroad signals to make a traffic light, which had just red and green for stop and go. Then in 1920, Detroit cop William Potts built one with 3 colors (red, orange and green). As you see here, people have tried other designs, like this funny dial one from Australia, but the three-color light is what keeps most of us from crashing into each other today.
Sometimes people make a wrong turn while driving. But imagine taking a wrong turn while flying a plane! Read on to fly through the math on one pilot who took a very wrong turn, which earned him the nickname “Wrong Way” Corrigan.
Drones don’t have to be used just for flying. Read on to see how they can help make Thanksgiving dinner, and fly through the messy math of cooking with a drone!
Bridges are neat structures that help us get across water. And this bridge in Midland, Michigan is especially cool because it’s a 3-way bridge! Read on to triple the math fun with this bonkers (and awesome) bridge.
Next time you drive under a bridge or overpass, look for a sign on the side with numbers on it. It will tell you the bridge’s height above the road in inches and feet. Why? So we don’t have what happened in this picture!
