ELI5: Explain Like I'm 5

Sidney Coleman

Sidney Coleman was a very smart physicist. He studied really, really hard and learned a lot about the world around us.

He had a special way of explaining things, like a teacher helping you understand things at school.

He was especially interested in something called "quantum field theory" which is a fancy way of saying he liked to study tiny tiny things that are very hard to see, even with really powerful microscopes.

He also helped other people understand difficult ideas by giving fun and creative lectures. His students loved him and thought he was very funny!

Sadly, Sidney Coleman passed away a long time ago, but his work and ideas are still remembered by many scientists today.
