Duality

Mike Tobar explains how quantum "duality" limits ultra-precise measurements. Mike breaks this standard quantum limit of measurement precision in order to explore things as diverse as dark matter, gravity waves, and radar. Duality is the fact that everything (photons, particles, ..., people, planets) are best described as both particles and waves at the same time - but that's not the only mind-bending idea in this episode. The search for dark matter means looking for a subatomic particle that has cosmic size, and Mike describes experiments using giant ultra-cold tuning forks that can ring for days!
