What happens when a young Indian engineer moves from the sweltering heat of Andhra Pradesh to the Massachusetts Institute of Technology (MIT), in a state notorious for its -15°C winters? He feels very cold and has to wear multiple layers of clothing, which he then finds himself wanting to remove whenever he enters a warm classroom. Kranthi Vistakula, who found himself in just this situation, credits a dazed mind, as well as his professors at MIT, for his decision to invent an all-weather jacket designed to cope with extreme temperatures—from the heat of Mumbai to the chill of a Mount Everest base camp.
