Physikalisch-Technische Bundesanstalt (PTB)
Jens Simon, born in 1962, has followed two academic paths as he moved between Braunschweig, Jülich and Cologne. One path led to a doctorate at the Technical University of Braunschweig in German linguistics on the language of the author Arno Schmidt. The other path led to a doctorate at the University of Cologne and the Forschungszentrum Jülich in theoretical physics on quantum dynamics with wave packets and trajectories. The synthesis of the two initially guided him into science journalism and writing, then – more than 20 years ago now – to the beautiful task of heading press and public relations at the Physikalisch-Technische Bundesanstalt. One of his tasks is to communicate physics and science.
Leitmotif
Always think first of those who listen to you.
Activities
Among the special activities of the PTB press office are publishing the science journalism magazine “maßstäbe” (each of the infrequent issues is produced in-house entirely, from the initial idea to the final layout), the magazine “Junge Wissenschaft” (an online journal for the primary publications of young researchers) and giving lectures on physics topics – in particular the unit system – to pupils, school teachers and the general public.
The 20th of May 2019 is a special day. From that day on, the old definitions of what a kilogram, a mole, an ampere and a kelvin represent, are history. The future of the International (…)
Scientists from the Physikalisch-Technische Bundesanstalt (PTB) have implemented a novel pressure measurement method, quasi as a byproduct of the work on the "new" kelvin. In addition to being new, this procedure is a primary method, i.e. it only depends on natural constants. As an independ ... more
Don't Give the Slightest Chance to Toxic Elements in Medicinal Products
Lead, cadmium, mercury, and arsenic do not belong in medicinal products. International requirements for the quality of medicines have therefore become more stringent and introduced new control requirements. Hence, it makes sense to use high-accuracy reference solutions with defined contents ... more
Measurement of the dynamic mechanical properties of viscous materials
In microsystems metallic components are increasingly being replaced by those from low-cost polymers. For the thickness measurement of polymers, there is now the DIN standard 32567 available, which describes both, optical and tactile surface measuring methods for the precise measurement of t ... more
The importance of traceability in laboratory medicine
World Metrology Day is celebrated annually on the 20th of May and this year’s focus on health provides an opportunity to emphasize the importance of comparable and reliable measurement results in laboratory medicine. more
How the Avogadro constant was measured for the last time
Since the 20th of May 2019, the mass unit kilogram is no longer defined by the international kilogram prototype but by the numerical value of the Planck constant, the most important fundamental constant in quantum physics. For this definition, the Planck constant needed to be measured with ... more
Natural constants take center stage
The 20th of May 2019 is a special day. From that day on, the old definitions of what a kilogram, a mole, an ampere and a kelvin represent, are history. The future of the International System of Units will see natural constants play the star roles. more
Gavin O’Connor was born in Dublin and completed a Diploma in analytical chemistry at Athlone Institute of Technology, Ireland, in 1993. He continued his studies in analytical chemistry to B.Sc. level in the UK before completing his PhD in mass spectrometry at the University of Plymouth in 1 ... more
André Henrion, born in 1957, studied chemistry at Humboldt-University in Berlin, where he received his doctorate in 1988 in the field of Physical Organic Chemistry. After working at the Academy of Sciences in Berlin for a short period he moved on to the Physikalisch-Technische Bundesanstalt ... more
Rüdiger Ohlendorf, born in 1959, studied chemical engineering with a focus on instrumental analysis at the Münster University of Applied Sciences. After working at ISAS (Institute for Spectrochemistry and Applied Spectroscopy) and at Schering AG, he moved on to the Physikalisch-Technische B ... more
