‘Vehicles and Transportation’
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....
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!
What do you do when you can’t break a weight world-record with your 1,100-pound pumpkin? You row it, of course! Read on to paddle through the math in this crazy world record.
If you’ve ever walked a dog, you know it’s usually hard to keep up with them. But now there’s a way that you and your pooch can exercise together and go the perfect speed for both of you! Read on to pedal through the math in this awesome exercise machine for you and your puppy pal.
We have lots of robots in our lives, but we bet there are few as cool as this real-life Transformer car! Read on to see how it works, and discover the math in these mutating cars.
Flying in an airplane really is a crazy idea. Jumping out of one with a parachute at 24 miles high is even crazier! But that didn’t stop Felix Baumgartner. Read on to jump into the math behind this crazy sky dive.
