CERN. Little Things are Big Science

NatIt cafe-foredrag om CERNs partikel-acellerator som eksempel på datamodellering i fysik. Foredraget holdes på dansk. Det er åbent for alle interesserede.

Foredrag ved PhD-studerende Morten Dam Jørgensen fra Niels Bohr Instituttet.

"Particle physics is a science defined by extremes. It is the search for the most fundamental truths about our universe with the largest instruments created by mankind. We look for the simplest possible connections between matter and energy with the most complicated technology ever developed.

The adventure starts at CERN in Geneva with the huge LHC accelerator complex and detectors the size of apartment buildings, but the truly global collaborations behind the experiments transgress boundaries with the LHC World-Wide Computing Grid. With over 250,000 processors and hundreds of petabytes of disk-space spread between member states it is also one of the largest computing operations in the world. Computing is a key ingredient in modern science and in particular in large experiments. To understand what is happening when protons collide, everything from the particle interaction itself to deformations in the 7000 tons detector structure due to tidal effects from the Moon is simulated. The experiments generate ~ 20 PBs of data every year, comparing data with simulation requires a journey into distributed computing and parallel processing on an epic scale."
