🎶 The Eureka Moment of Theodor Kaluza

In April 1919, Theodor Kaluza, a 34-year-old German mathematician, experienced a significant breakthrough while working in his study. During this moment, his 9-year-old son was present, often accompanying him. Kaluza, deeply immersed in his calculations, suddenly reacted with great excitement. He abruptly stood up, slammed his desk, and began singing an aria from Figaro. This pivotal moment marked Kaluza's realization of a groundbreaking idea: the possibility that our universe might have more than the familiar three dimensions of everyday space. The evening's program delves into this revolutionary concept, tracing its evolution over the past eight decades and exploring current theories on the existence of additional dimensions, with references to the work of Calabi-Yau.
