If you want to know how to win those “guess the number of M&Ms in this jar” contests, you should watch this video. In it, Adam Micolich – a physics lecturer at the University of New South Wales – explains how to scientifically calculate the number of the M&Ms in a jar. Skip to the 3:30 mark for the fun stuff.
Andrew Hicks, a mathematician at Drexel University, used some of his math skills to make a mirror that reflects an image without reversing it.
It’s called a non-reversing mirror and the effect can be recreated pretty easily. Just take two mirrors and put them 90degrees to each other and look directly at them.
Hick’s mirror is slightly more complex because its all on one mirror. I think he uses some sorta parabolic math mumbo jumbo to make his. Either way, its pretty cool.
