Well, I went down to Wellington last Thursday and presented at the Science Express event at Te Papa. It was the third time I’ve done a talk in that manner on the Large Hadron Collider, and it was for me intriguing how the audiences have picked up on different things each time.
The first time (Hamilton, late last year) the audience wanted to know about the structure of the nucleus – what’s in a proton? (answer – three quarks, or at least we think so) – what’s a quark made up of? how do they interact? and so on. (If this sounds like you, have a read about the ALICE experiment at the LHC).
