Some years back, I considered a degree and career in physics. I’d been an enthusiast for years, but I spent more time studying philosophy. I got my first taste of theoretical physics in the Ninth grade after my friend JK gave me a copy of Hyperspace to read.
Michio Kaku’s explanations of higher dimensions through metaphor went several steps further than Flatland did, and his book brought me previously unknown levels of intellectual stimulation. I lacked the capacity to experience the fourth dimension in a more physically direct way, but Kaku’s descriptions allowed me to conceptualize it mentally.
The notion that humans could gain knowledge just by running mini-simulations is cool.
