I was watching a video about the high jump and how a new technique allowed Dick Fosbury to win a gold metal in the Olympics even though many of the other athletes were more physically gifted. His new technique, the Fosbury Flop, allowed him to clear a higher bar without actually jumping higher. This video gives a great explanation of how it works:
After watching this, I showed our kids a cool “trick” that my dad had shown me.
You can try with your hands at any 2 points that you want, but they always end up at 18.
Why do your hands end up at 18?
Because 18 is at the center of mass. When you start, more weight is on the hand that is closer to the center. That means there is more friction on that hand and the yardstick only slides on the hand that is farther away. As the hand that is sliding gets closer to the center, it takes on more weight, and the other hand slides. Eventually both hands end up in the center.
I love studying science because it reveals how God made our universe. I understand how the yardstick balances, but God asked Job if he knew how the clouds were balanced. Job 37:16 I never even thought about the fact that the clouds are balanced. We will never fully understand everything that He has made, but as we learn about His creation, we learn about Him.
