A few months ago, a group of really smart physicists made a discovery. They were working on an experiment involving muons, which are small subatomic particles, when they found that these particles appeared to be breaking the laws of physics. It was an amazing discovery but what does it mean? And how does it affect you and me? Research Associate for Fermilab Saskia Charity joins William Shatner on this week's episode of 'I Don't Understand' to explain what a muon is and why we should care.
