I may have mentioned before, the Standard Model is about 50 years old now. It embodies a huge amount of human endeavour and understanding, and I try to explain it in my book, A Map of the Invisible (or Atom Land in the US/Canada). Thanks to the team at TED Education, and the excellent animation of Nick Hilditch, here is a TEDEd lesson I wrote – with important help and support from ATLAS colleagues. There are also related lesson resources etc on the TED-Ed page. Hope you find it fun and enlightening, please share!
