CERN Large Hadron Collider
19 июля 2022 г., Швейцария ⋅ ☀️ 27 °C
Today we got to see the CERN Large Hadron Collider. By "see it" we actually didn't see anything that cool. The LHC is actually 100 meters underground and has restricted access. It is underground because the radiation it produces needs proper insulation, and that was the most cost effective alternative to building a large concrete structure around the experiment. So needless to say, no one is often "down" there observing anything. At least not during the experiments. All the data is collected by sensors and computers

The goal of CERN and the LHC is to reproduce hard to naturally observe scenarios regarding particle collision and to observe, and accumulate anti-matter. Its most famous recent discovery was the Higgs boson.

The equipment used to accelerate particles was actually built little by little as the LHC is only the most recent addition. Previous accelerators such as the Protons Synchrotron and the Super Protons Synchrotron (SPS) are smaller and work in series with the LHC. The smaller accelerators speed up hydrogen particles before releasing them to larger accelerators. The LHC is the final step (before collision) and can get the particles up to top speed.

Here's a 5 min video that explains this better than I probably can.

Путешественник a few other interesting facts. the large collider is 27km long (circumference) and the particles that traverse through it go at 99.9999% the speed of light. Roughly 11,000 rotations on this 27km circular track per second.

Путешественник A future use for the Rt128/Rt93 loop?? they are smashing stuff out there every day. I know...I know... you're lucky if reach 25mph out there.

CERN is the second
10 апреля, Швейцария ⋅ ☁️ 12 °C
Here I found myself at my second particle accelerator on this trip, at CERN the largest in the world. There's a shiny new science exhibit, which showcases the ambitious science and engineering that happens here.

The art exhibits were quite trippy. I got sucked into the high dimensions of the glowing mobius.Читать далее

CERN the LHC and the UN
10 июля 2017 г., Швейцария ⋅ ⛅ 21 °C
Geneva is only a quick stop for us on our way to Italy. We have today to see as much as we can. First stop CERN. It is very difficult to get on a guided tour at CERN. They only have groups up to 24 people with 12 pre-booked 15 days before the tour and the remaining 12 just 3 days before. The booking site opens at 8.30am Geneva time and books very fast. One of the times I tried, it was booked in less than a minute. It would almost be easier to develop the Grand Unified Theory of Partical Physics, seriously. So just the static tours for us, which as it turned out were more than enough for our non physicist minds to deal with. Once you ramp up the grey matter a notch or two, you start to appreciate this place and all that you are looking at. In a sentence, this place is cool to visit. The engineering let alone the science is amazing. Completely the opposite approach to understanding, well everything compared to religion. Also provides perspective on why most adopt religion over science because the science is oh so complicated. Anyway a couple of hours flew here and I could have stayed a couple more.

Another tram ride to the opposite end of the city but still only about a 30 min. ride to visit the UN. This wasn't part of our original plans but worth the visit just the same. We got a brief history of how the UN was created after the failure of the League of Nations with the start of WW2. a tour of the building and various UN conference halls and the process of how they work. I did learn some things and got a more appreciable view of just what the UN does and achieves. Most have a perspective that it is a toothless tiger but its charter is not about a strong arm but a diplomatic one. Lots of good and goodwill from all over the world happens here.

We also visited Lake Geneva and got caught in the rain. Ate at a couple of traditional Swiss restaurants and realised I have been trying different beers as we have been traveling. I am taking pics of the ones I like. Thought about buying a watch here. Watches everywhere in Geneva, even a watch museum. Too many options though and a little research informs you, probably about the worst and most expensive place to buy a watch. Time to move on.Читать далее

Geneva
19 апреля 2022 г., Швейцария ⋅ ⛅ 17 °C
Geneva is located in the southwest of Switzerland where the Rhone River exits Lake Geneva (Lac Leman, in French). Geneva is a global city, hosting a lot of international activity ( see another post).
Historically, Geneva was a border town with all the trading that goes with it. The Rhone was for many years the northern border of the Roman empire, and the city's location is likely due to an ancient bridge located here.
The 1st picture looks out to Lake Geneva from near where the Rhone flows out. To the right is the Jet d'Eau, the water jet that shoots 120 meters high and has become a symbol of the city. The 2nd picture looks down the Rhone from under the bridge at the point where the river begins. The old town (see another post) is on the hill to the left of the the river.
The 3rd picture is the floral clock in the English Garden along the lake shore.
The 4th picture is the opera house, and the 5th picture is in the Bastion Park. During the Reformation (see another post), Geneva was one of the most heavily fortified towns in Europe: a staunchly Protestant town surrounded by largely Catholic regions. Most of that has been dismantled, but this park is in one of those areas, in between the inner bastion and the 2nd wall.
The last 2 pictures are for the science geeks: Geneva's other famous resident, CERN. The particle physics lab is world renown. The 2 pictures are at the Atlas site, the only one of the 4 observation sites in Switzerland. 1 is of the outer wall. The other is the control room.Читать далее

Voir où se passe la recherche nucléaire dans le monde, ça claque. Voir où a été découvert le boson de Higgs ça claque encore plus. Voir où se passe Anges ou Démons ça claque très bien.
