PTB

Dr. Dr. Jens Simon

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.

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 (…)

    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 most accurate optical single-ion clock worldwide

    Atomic clock experts from the Physikalisch-Technische Bundesanstalt (PTB) are the first research group in the world to have built an optical single-ion clock which attains an accuracy which had only been predicted theoretically so far. As early as 1981, Hans Dehmelt, who was to be awarded a ... 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

    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

    The Best Measurement

    It is now more than 30 years since attempts started to find a way of defining the kilogram based on an atomic constant or a fundamental physical constant. Since then, two methods have advanced sufficiently far to make it likely that there will be a new definition within the coming years, na ... more

q&more – the networking platform for quality excellence in lab and process

The q&more concept is to increase the visibility of recent research and innovative solutions, and support the exchange of knowledge. In the broad spectrum of subjects covered, the focus is on achieving maximum quality in highly innovative sectors. As a modern knowledge platform, q&more offers market participants one-of-a-kind networking opportunities. Cutting-edge research is presented by authors of international repute. Attractively presented in a high-quality context, and published in German and English, the original articles introduce new concepts and highlight unconventional solution strategies.
