The Physics of Superheroes

(June 15) This was taken by me somewhere between 30-35 years ago, I think, but planned out completely by my dad. This is an old scan of old photos, pieced together today into the original sequence, so forgive the quality. My dad originally built the cavalletti for my horses. A family friend was very impressed by that and wanted a photo of them to find out what they looked like. So my dad thought it would be great to get a sequence of him jumping them. He had me take a photo of him running toward the cavalletti stacked up and then running away from them. Then we took the top one off, put it on the ground, where it was about two feet high, and took a picture of him jumping it from the perspective of the ground. My mom put them together and sent them to our friend, telling her that this was how to use the cavalletti properly. My dad's a superhero, as you can see, and a physicist. I only hope I inherited some of his creativity and sense of humour. Happy Father's Day, Papa!
