In today’s episode, Gordy explores a mind-bending innovation in modern physics: filming light itself in motion—at a trillion frames per second. Sound impossible? Welcome to femto-photography, where researchers at MIT figured out how to capture a single pulse of light as it travels through a Coke bottle, scatters off an apple, and even starts forming shadows in real time.
This isn’t slow motion. It’s slow-light—and it has game-changing implications: from seeing around corners, to autonomous navigation, to non-line-of-sight medical imaging.
Gordy walks through the tech behind the scenes—streak imaging, femtosecond pulses, and how hundreds of repeated experiments get stitched into one real-time light show. Whether you’re into photography, physics, or just want to know what light looks like as it moves, this one’s for you.
So what does light actually look like in motion? This episode has the answer. And yes—it’s as wild as it sounds.
