I went, however, to see the exhibit on the large Hadron Collider. It was a major disappointment. There were lots of pieces of hardware but the video presentation was, imho, awful. Just building the LDC was a major engineering feat. Nothing, no pictures. No real explanation of how it works. Like, we shoot this beam and it gets squeezed by these magnets (picture.) Nope, just a bunch of talking heads in a conference room. Lots of superficial talk about the Higgs Boson. Not my thing.
Fair winds and following seas :)
