Juho Kilkki has been a bit obsessed with Isaac Newton for the past five years. According to his story, it all started while training with a five kilogram workout ball and a friend asked if he could do a backflip after throwing that ball mid-air. Had he given up after his first few attempts that day, the whole experiment would have been done and over with. Instead, Kilkki’s infatuation with Newton’s laws of motion were born.
This past summer, Kilkki teamed up with Valio Academy to test out that initial curiosity with a ramp, skis, a set of dumbbells, and a lake for a landing spot. They concluded three things from Newton’s The Principia, interpreting his words in modern terms a skier can appreciate:
(I) If you forget to set your spin/flip on the takeoff, it’s quite hard to do so midair.
(II) But if you happen to have a pair of dumbbells with you in the air and you throw them, the dumbbells will also throw you.
(III) The bigger the dumbbells, the more you spin/flip.
Months later, with plenty of snow on the ground now and a lot of curiosity left, Kilkki returned for more.
“I doubt any great discoveries were made here but dropping in on any of these tricks sure felt like the boldest of guesses,” he says.
