… Feiner Services
Feiner Services is a convenient umbrella term for the ventures of the freelance physicist Franz Feiner, Ph.D. Founded on September 16, 2004 in Munich it is now located in the small Upper Bavarian village Pürgen not far from Lake Ammer and next to Landsberg am Lech (where Johnny Cash formed his first band "The Landsberg Barbarians").
… Franz Feiner
I am a diversely interested omnivorous reader who likes to figure out how things work and how technical goals can be achieved with simple means. I started early in life to explore devices: As a preschool child I liked to disassemble mechanical alarm clocks and learned to reassemble and repair them. When I was receiving secondary education, I started to teach myself coding and electronics with single-board computers. And then I found the ultimate toolkit for disassembling and reassembling the universe: mathematics and physics. This leads us to …
I studied experimental physics at Ludwigs-Maximilians-Universität in Munich. As secondary subjects I chose physical chemistry and electronics — inorganic chemistry as well as mathematics being anyway integral parts of the study of physics.
Working on my diploma thesis on the subject of intermolecular forces, I built a piezo-driven device for bringing two surfaces into close proximity (nanometer-range distance) and developed an optical method for measuring the forces acting between these surfaces as well as all the voltage sources, signal-conditioning (e.g., a lock-in amplifier) and control electronics (e.g., a small computer to program the step sequences of the piezo actuators).
As postgraduate student I spent a term at the Technical University of Munich learning the basics of Fourier transform infrared spectroscopy and gel electrophoresis.
Returning to Ludwigs-Maximilians-Universität I became a researcher in nonlinear optics investigating frequency doubling of near-infrared light interacting with organic molecules (second harmonic generation). This was also the subject of my Ph.D. thesis. Again, I built all the necessary electronics (e.g., a boxcar averager) and also diverse optical elements (e.g., a Raman shifter).
… my Additional Skills
Before I embarked on my study of physics I was a radio operator in the German armed forces and in the ensuing alternative service at the Max Planck Institute of Psychiatry I learned to interpret sleep patterns in EEG recordings.
In my first position outside academia I was employed to develop and test detectors for ionizing radiation.
Then I switched roles and wrote 3D-kitchen-design software.
Changing my occupational field once more, I found employment as a scientist at the German Federal Office for Radiation Protection where I helped to assess the biological effects of non-ionizing radiation. This position shifted my focus to the medical applications of physics.
Subsequently, I was hired by a medical device company whose main products are nebulizers. There my first assignment was to develop aerosol sensors and a nebulizer test rig. The second one was to find new ways to generate aerosols.
The last position I held as an employee was for another medical device company, where I developed an ultrasonic blood flow meter based on the transit-time method.
In my free time I also like to learn about science-related subjects. That's why I love to go to the Deutsches Museum of Masterpieces of Science and Technology and why I like to give talks on these topics. So, when the opportunity arose, I jumped at the chance to deliver a series of lectures at the Landsberg folk high school on how mathematics, science, and technology developed through the ages and how they influenced the course of civilization.
