Recently, when I was searching Ted.com I came across Riddle videos. The video that I want to show you was created by Dan Finkel who is a math teacher. He created many videos on ted talk and Here is one of them. In this riddle you are trying to take measurements of time using a-fuses. I personally didn’t know how to solve this riddle at all and had a problem with understanding how to make the fuses to burn out equally to the half. This type of videos really helps you to improve your imagination and ingenuity. I highly recommend watching this video and figuring out how to do it by yourself. Good luck. Questions: 1. Were you able to solve the riddle? 2. Is this type of learning new things and solving problems friendly and efficient? Why? 3. Did you come across any of his videos before?
