Triumph for the Standard Model of Physics
Triumph for the Standard Model of Physics
After years of research into the magnetic dipole moment of muons, theory and experiment have finally been compared with precision - with excellent agreement. One of the major cracks in modern physics may now have been closed: for years, scientists puzzled over why the measured values for the magnetic moment of muons did not match the calculations derived from the generally accepted Standard Model of particle physics.

A Snapshot of Relativistic Motion: Special relativity made visible
A technical trick has been used to simulate a speed of light of only 2 m/s in the laboratory. This made it possible to reproduce the relativistic Terrell-Penrose effect for the first time. When an object moves extremely fast - close to the speed of light - certain basic assumptions that we take for granted no longer apply.
