(Sunny day at CERN)
We visited Switzerland yesterday afternoon, as you do. We were there for the science. You may have heard of Conseil Europeén pour la Recherche de Nucléaire?(Me neither.) CERN, for short was set up after the Second World War to create a place in Europe where scientists could be scientists and share their work with this new postwar world. During the war a lot of scientists left Europe to work in the United States. People like Robert Oppenheimer, who invented the atomic bomb. Albert Einstein moved before the war and became an American citizen in 1940.
(We booked spaces on the free tour)
More recently you may have heard of CERN because of the Large Hadron Collider? No? Okay… if you had I could just bypass an explanation of it… are you sure you haven’t heard of it? If you’re sure I’ll give it a go but don’t ask any questions, I don’t know the answers. The Large Hadron Collider, LHC for short, is a device thought up by some people from CERN to work out what happened at the beginnings of the world. So far so good. Everything started off 13.8 billion years ago with the Big Bang. That’s the theory and scientists love theories but the theories bring up lots of questions and the only way to answer those questions is to create experiments. CERN is a place where scientists can perform experiments.
(Here’s our tour guide in front of lots of information)
Scientists have to be incredibly patient people because experiments take a long time, they often don’t work and then they have to keep tweaking things and re-experimenting. What’s more, they have to create devices or machines for their experiments. The people at CERN have been creating theses machines since 1949. We saw one that was created in the 1950’s called the Synchro-Cyclotron, the main part of it was bigger than Ruby and was housed in a three story building.
(Inside the tube of the LHC)
Two of the scientists involved with the first Synchro-Cyclotron experiments are still working at CERN, Maria and Giuseppe Fidecaro. Not because they have to, they really, really like being around science and scientists.
(There’s a lovely article about them at https://www.symmetrymagazine.org/article/february-2014/couples-history-intertwined-with-60-years-of-cern)
(All the information from experiments since 1949 is stored on tape. They are starting to move it on the cloud)
And that was just the beginning. The scientists kept designing bigger “machines ” as the experiments got more complicated or as they say, interesting. Which leads us to the LHC (remember, the Large Hedron Collider?). Now, if you thought the Synchro-Cyclotron was big, wait until you hear this… The LHC comprises a 27km long circular tunnel built underground with 4 experiment buildings attached. What’s more, it’s located just across the border in France! (Side note: there’s an open border between Switzerland and France at CERN… something similar could be useful to us if the exit goes ahead.)
(The location is surrounded by corn fields and snow capped mountains)
What does the Large Hedron Collider do? It makes teeny tiny particles move very, very fast and then bump into each other. And then it measures what happens next. We didn’t get to see the LHC – it’s closed down for an upgrade which will take two years! Can I refer you back to scientists having a lot of patience. But we did get kinda close… our tour guide, who was from South Africa, is a Phd student proving her own experiments at the LHC. I did not understand her experiments and you’ll just have to trust me they sounded impressive.
But… there is one thing that was invented at CERN, that you use every day. It was invented by Tim Berners-Lee, a computer scientist. He invented The World Wide Web here. What we all call (imprecisely as it happens, scientists are very precise…) the Internet! Without CERN you wouldn’t be able to read this… well yes, of course you could be spending your time more wisely practicing French or going for a long walk.
Thanks a lot, CERN, Mairead.
(By the way, just to let you know in case you were worried (I was..) I checked and even though nuclear is in their name, it’s not like nuclear power or war or weapons… it’s just to do with the nucleus of atoms.)

(There’s CERN)
(The front of the Monastère Royal De Brou)
(Exhibition of old techniques for painting)
(Reproduction of roof tiles)
(Stairs to Apartments of Princess Margaret) We make energy when we drive and we have been driving for 90 minutes today. We also make energy when the sun shines and although it is much colder today (7 degrees Celsius this morning) the dark clouds are gone and the sun is shining on our solar panels.
(Ceiling over her tomb)
(Her motto… Both fortune and misfortune make a woman stronger)
(Princess Margaret of Austria)
(I love the cloisters)
(Can you see the fancy tile mosaic on the roof of the church?)
(It started raining while I was inside)
(Tomb of Philibert the Handsome…)
(…and just a few feet away, the tomb of Princess Margaret of Austria)
(46 minutes at 60 degrees)
(There they go…)
(You can tell a lot about a place by what they put in their supermarket foyer….
(This old wooden wine press was also in the foyer – wine production is big here too)
(An old tin sign on the former train station wall)
(This tower reminded me of Reginald’s tower in Waterford)
(That’s the post office clinging to the edge of the hill and that second tower belongs to the church)
(Just in case you were wondering where meat comes from…)
(The long road)
(There would have been a barrier across the road here, when the greenway was a train track)
(Noticed this hanging on a tree on my way back. You are the master of your life and whatever the prison you have the keys. The Dalai Lama)
(La boulangerie)
(Not Brennan’s but sure we’ll be grand…)
(Can you make out their opening times? 6.30am to 7.30pm every day, exceptions: closed all day Tuesday and closed thirty minutes early on Sunday)
(Place Notre Dame, Dijon. Even in this small section can you see two church towers?)
(This was the huge door to the art gallery)
(These three were portraits of the artist’s mother, they are huge, he must use scaffolding)
(And another church)
(This bee may have come from the hives they had in the park)
(The alleyway to a side entrance. Can you see the little door cut into the big door on the left?)
