Thursday 21.2 at 6pm, Physics at Arkadia: ‘The particle zoo: beauty, symmetry and symmetry breaking’ by Rose Lerner

You are very welcome to visit us at: / Arkadia International Bookshop and “like” us if indeed you do!

Dear friend of Arkadia,

You are invited to “The particle zoo: beauty, symmetry and symmetry breaking” by Rose Lerner on Thursday 21.2 at 6pm at Arkadia (Nervanderinkatu 11)

The talk is aimed at non-scientists, so please don’t worry if you don’t know anything about particle physics. We will attempt to explain from the very basics, and everyone is welcome.

You may have heard of some fundamental particles, such as the electron and the Higgs boson. You may even have heard of some non-fundamental particles such as the proton and the neutron or even the Large Hadron Collider at CERN, which is attempting to discover new
particles. But which other particles exist? What makes a particle fundamental? And what role do beauty and symmetry play in particle physics?

In this talk, Rose will introduce the fundamental particles that form our universe, such as quarks, neutrinos and Z-bosons. Rose will also discuss the role of antimatter in the evolution of the universe. Then, more importantly, she will attempt to explain the beauty and symmetries linking the theory behind these particles. She’ll also introduce the Higgs boson, which plays a really important role in the evolution of the Universe, and causes a particular symmetry to be broken.

Rose hopes you will leave with a deeper understanding (or appreciation) of the beauty of fundamental physics, and hopefully also lots of new questions about the universe that we live in!

There will be plenty of time reserved for discussion and we welcome all your questions.

Rose Lerner works in the cosmology group at Helsinki University and has given many popular science talks at Arkadia (
