I Am Isaac Newton is an episode of Xavier Riddle and the Secret Museum.
Xavier tries mini golf for the first time, and things don't exactly go as planned. No matter how hard and fast he swings, the ball never goes in the hole... To the Secret Museum!
Our trio are sent back in time to meet an expert in the laws of motion: Sir Isaac Newton. Isaac is in the middle of his own problem, trying to figure out how he can out jump boys who are clearly bigger than him. Instead of attacking the problem hard and fast, Xavier style, Isaac takes a much calmer approach with the use of a thinking tree and a thinking kite. When he finally solves his problem and wins the long jump competition, Xavier realizes how much better it is to slow down and think through problems.
I Am Isaac Newton, along with its sister episode, I Am Golda Meir, was released on the PBS Kids website and video app on November 11, 2019. Both episodes aired a week later on PBS at 9:00 AM EST.
The story of an apple falling on Isaac Newton's head is referenced throughout the episode, as in the opening and closing segments, an apple falling is used to demonstrate gravity, and the kids sit under an apple tree.
