So I started our picture where we had supercomputers, at the University of Illinois. We went to the University of Michigan, we got the NSFNet funded. And now we're going to fly across the ocean to CERN. CERN, of course, is a high-energy physics laboratory. They do this 26-mile circle and smash particles and take pictures of the smashing particles and looking for the Higgs Boson. Or found the Higgs Boson. It's a really cool place, I recommend that you visit. The CERN is a place that physicists from all over the world visit, live at, and collaborate with. For experimental physics, it really revolves around those experimental facilities. And so regardless of whether you live in Russia or Australia or Germany or America or Japan, if you're an energy nuclear physicist, you have got to work with CERN or spend time at CERN. And those who spent time at CERN tend to make the best discoveries. And so, these projects have such long lead times, and they take so many different kinds of talented people, you know they're metallurgy, welders, physicists, engineers, designers, project managers, there's a ton of people involved in it. And it's a pretty well funded operation. And everyone's pretty smart. So one of the things that they do is they have fun. They have these clubs, like the softball club, the cricket club, the blues club. And, and it's kind of like these people are somewhat away from home a lot. And so they just have fun with each other. This is a picture that I will show you of the Cernettes. They are famous for being the first band photo on the web. Some people wonder if they're the very first photo on the web. But they are a doo-wop group and they sing sort of, 50s style doo-wop songs. They are very fun to watch. But their songs are about like particles and Internet and modems and stuff like that, stuff that I care a lot about. Sadly, they've doing this since the 1990s you know, 90, 91, 92 kind of time frame. And they all grew up and their kids grew up and their kids are all in college and so they did their farewell tour in 2011 and I, and one of them's moved to Australia so we don't know if the Cernettes are ever going to get back and together and sing but for now they're on permanent hiatus. But, for your viewing pleasure take a quick look at one or more of the Cernettes songs. So like I said, you should go visit CERN. I have had the great fortune to visit CERN. I had visited CERN with on professional in a professional role, I helped them record lectures with my Sync-O-Matic software that you may have heard me talk about. I, I have visited sort of in helping other technology things and I teaching and learning with technology and things like that. And so they've got a a wonderful cafe. And if you were working with people, you get to go in the back and hang out. That's pretty cool. They also have a wonderful museum that you can go see the first web server and all kinds of other cool stuff. And in 2006, I was lucky enough to have an invited talk at CERN where I talked about Sakai and how they might use Sakai to do collaborative work, and I brought my family with me. And so my wife Theresa, and my daughter Mandy, and my son Brent, and there's me. we were in the pit, and this pit is like, like eight or nine stories underground, it is six stories tall. This is where the beam comes in right here. It's three stories from the bottom of the pit. The pit is six stories tall. At this point the it was only less than one-third complete and so we could go on a tour, and so I have a family photo with hardhats in the CERN Pit. And that's pretty cool. Another time I visited I went and sang with one of our University of Michigan physicists. And that would be this guy right here, his name is Steven Goldfarb. And he's a physicist that works on the Atlas project, but he also is the band leader of a all-physicist band called the Canettes blues band. He let me sing a song. I was coming to do some video work for him. I happened to be in the area and I just stopped by on one of my trips and me and another Michigan staffer, we grabbed a couple of cameras and made some music videos for him. We put the Cernettes, some of the Cernettes music videos up on the web and then they let me sing one song called I Got My Mojo Working and so I got I'll share with you the video Got My Mojo Working. That's just, oh so, everybody in this band is a physicist. And pretty much everybody dancing is a physicist too. Now the reason I'm showing you all this is to give you a sense of the energy and joy, in addition to the hard work, that goes on at CERN. So I don't know if you noticed, halfway through, I knew that song by heart, but I had still written lyrics on my hand and so halfway through you can see me look at my hand to check the lyrics that I knew. Made me look like a dork. I'm not, I really want to sing. I'm just not a very good singer, and thankfully Steve let me sing with the band. So, back to the topic at hand. In 1999, I visited CERN as one of my first tasks at the University of Michigan to help them with lecture recording. And I said hey I got a camera, you know, are the inventors of the World Wide Web here. And we still had a little bit of the televison show going back then. So I went and interviewed Robert Cailliau who was still at CERN. He was just sort of across the street from the cafeteria. And we walked in to his office and gave him the microphone and just started talking about the beginnings of the World Wide Web. And Robert Cailliau is the co-inventor of the World Wide Web along with Tim Berners-Lee who, who built it at CERN. So let's take a listen to Robert Cailliau.
