If you could have a conversation with any historical figure, living or dead, while riding a roller coaster, who would it be, and what do you think their reaction would be to the roller coaster experience?

If I could have a conversation with any historical figure while riding a roller coaster, I would have to choose Albert Einstein. I think his reaction would be one of wonder and excitement. He was a great lover of science and adventure, and I'm sure he would appreciate the physics behind the roller coaster and the thrill of the ride. He might even compliment the engineers who had designed the roller coaster. He would most likely also be quite intrigued about the changes in gravity and velocity experienced by the riders during the ride. I'm sure it would be a fun and thrilling conversation!
