Das Baryon-Antibaryon-Symmetrie-Experiment (BASE) am Antiprotonen-Entschleuniger des CERN hat neue Grenzen für die Stärke festgelegt, mit der sich Axion-ähnliche Teilchen in Photonen, die Teilchen des Lichts, verwandeln können. Dies ist besonders bemerkenswert, da BASE nicht für solche...

In Braunschweig and Berlin, time comes from atomic clocks, lengths are measured far into the nano-world, scientists do research on fundamental questions concerning the physical units, and the employees in the laboratories calibrate measuring instruments, meeting the most demanding requirements. Therefore, the Physikalisch-Technische Bundesanstalt is among the top names in metrology worldwide. As Germany's national metrology institute, PTB is Germany's highest authority when it comes to correct and reliable measurements. It is the supreme technical authority of the Federal Ministry for Economic Affairs and Energy (BMWi) and employs a total of approx. 1900 staff members. PTB operates an integrated 
quality management system which covers the four interlinked field of business. (
