CERN textile collection (2019)

From September 2019 onwards, CERN’s new textile collection is offering T-shirts, hooded sweatshirts and even baby vests, all with original scientific slogans. Find out below what’s behind the slogan.

The person in this T-Shirt is 13.8 billion years old

Like the universe, everything around us and the screen you’re looking at now, you too are made up of elementary particles, which appeared at the time of the Big Bang 13.8 billion years ago. No wonder you feel tired sometimes!

This T-Shirt is made of 9 million billion billion quarks

Like all the matter we know, this T-shirt is made up of atoms, which in turn are made up of a nucleus surrounded by electrons. The nuclei are made up of protons and neutrons, which contain quarks. With no measurable size, electrons and quarks are elementary particles, meaning they do not contain any other particles. Their mass is so minuscule that a huge quantity of them is needed to make just a few grams of matter.

This design is an illustrative representation of the particle tracks produced at the moment of a high-energy collision in one of the detectors of the LHC accelerator. These detectors are like huge digital cameras, which record several hundreds of millions of collisions per second!

Lagrangian of the Standard Model of particle physics

This formula is the mathematical representation of the Standard Model of particle physics, the theory that describes the elementary particles and the forces that bind them together. The first line describes the forces: electricity, magnetism, the strong nuclear force and the weak nuclear force. The second line shows how these forces act on the elementary particles of matter. The last two lines describe the Higgs boson and the mechanism by which particles acquire their mass.

I am the best you can make out of quarks and electrons

Your body is made up of cells, which themselves are formed of molecules. These molecules are made up of atoms, each comprising electrons and a nucleus of protons and neutrons. Protons and neutrons are combinations of quarks. With no measurable size, electrons and quarks are elementary particles, which are not thought to contain any other particles.

World Wide Web Born @ CERN

In 1989, Tim Berners-Lee invented the World Wide Web (not to be confused with the internet) while working as a computer scientist at CERN. The web was designed to facilitate the exchange of information between the scientists working on CERN’s experiments, wherever they happened to be in the world. It has since become an indispensable tool for billions of internet users.

I want to be a particle physicist

Every year, CERN trains several hundreds of students from all over the world, not only in physics, but also in the fields of engineering, computer science, administration and more.

My mother is a supernova

All elements, except the three lightest, are products of reactions between atoms that take place inside stars. When a star dies in an explosion known as a supernova, these elements are thrown into space. Some have ended up on Earth over the last four billion years that our planet has existed. We’re all stardust!
