Postdoctoral associate Stewart Isaacs SM ’19 PhD ’24 speaks with Physics Today reporter Toni Feder about his passion for the sport of jump roping, research into solar-powered egg incubators for use in West Africa, and his work at MIT focused on addressing climate change and social inequities through the development of clean energy systems. “In jump rope, you have the basic building blocks of tricks. You need to combine them in ways that look interesting and are creative and fun to do. In engineering, you have the basic building blocks of physics. When you need to solve a problem, you need to come up with a creative solution to get there,” says Isaacs of the intersection between jump roping and scientific research. “And jump rope is hard. To be really good at it takes a lot of effort. The habits of working hard and problem-solving are also very useful in engineering.”
