BM: This is something that happened when I was walking through the hall to set up in here there was a couple of girls looking at the "Flipping Image" exhibit and I heard one say to the other one "It's not rocket science." I'm trying to figure out whether that's a good thing to hear or not.
HF: It is quite, it's such an interesting - thing because rocket science is incredibly simple and it's a really it's a really bad thing that people say because - you know the science that took, you know, the first rocket to the moon the first rockets into space - incredibly simple stuff, you know. And the computing power that was involved - you know you can get in your palm hand-held computer these days you know. So, when anyone says it's not rocket science well - yeah - a lot of science isn't rocket science. It needn't be really complex or complicated. I guess if you - maybe maybe that person there who said that wanted it, you know was expecting it to be more taxing and more, you know, more difficult. I don't know. But sc- you know, you can find, you can find a lot of complexity in the simplest of things. Mirrors are a classic example. so. yeah. They're not rocket science but they're very difficult to - they're really intriguing. You can do an awful lot with them. So.
