SciShow: Quantum Tunneling Takes a Surprisingly Long Time

Teacher or professor: SciShow
Subject: Science
Content of the Lesson: Quantum tunneling happens when a particle seemingly teleports across a barrier. But despite how instantaneous this event sounds, recent research suggests that it doesn’t happen nearly as fast as you might think. Hosted by: Michael Aranda SciShow has a spinoff podcast! It's called SciShow Tangents.
