Neuer Imagefilm

Was ist die PTB? Man kann sich durch Chroniken wühlen oder Jahresberichte lesen, um diese Frage zu beantworten. Oder man nimmt sich für einen ersten Eindruck gut 6 Minuten Zeit, schaut sich einen Imagefilm an und hört, was einige Mitarbeiterinnen und Mitarbeiter über die Institution sagen.

Riddle of matter remains unsolved: Proton and antiproton share fundamental properties

No difference in protons and antiprotons have yet been found to explain the existence of matter in our universe. However, physicists in the BASE collaboration at the CERN research center have been able to measure the magnetic force of antiprotons with alm

PTB - The National Metrology Institute of Germany

PTB's profile of tasks

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 Opens internal link in current windowquality management system which covers the four interlinked field of business.
