We had the pleasure of hosting Katie Mack who presented her new book "How to Build a Universe". She gave an engaging presentation about what the universe is made of and - more importantly - all the lies we're being told about it. The question of what exactly is "fundamental" in physics is a very tricky one: Is it particles? Is it fields? Or is it something even more abstract, like symmetries?
If you want to learn more about these topics and also read Katie's rant about why the proton is such a mess, get her book coming out in March: You will find it in the CERN Bookshop and Library.
