Physics, Science, Engineering, and a Lot of Fun

I am running a small engineering consultancy together with my husband. Following Star Trek terminology, he is Chief Engineer, and I am Science Officer.

In overly correct legalese, my job titles according to our business licences are 1) Consulting Engineer in Applied Physics and 2) IT Consultant.

We specialize in planning of heat pump systems with unconventional heat sources, that is a combination of an underground water tank and an unglazed solar collector. 'IT' means: playing with control units and data monitorin.

Solar collector for harvesting energy from ambient air.

As we run a German blog focused on this system and I also devote a 'sub-division' of my English blog to it, I use this site ( mainly for consolidating resources and links - in the same way as I curate security / PKI related links. Perhaps these link dumps will not be very useful for anybody but myself.

I once was a laser physicist and a materials scientists - my specialties having been high-temperature superconductors, laser-materials processing with Excimer lasers, and the microstructure of stainless steel. Then I turned to IT security, IT infrastructure and IT management for more than 10 years.

In 2012 I felt the urge to reconnect with my roots as a scientist and engineer, and we started working on our own heat pump research project in stealth mode. It turned to a second 'branch' of our two-person business. There are connections between my different fields of expertise - IT security and heat pumps - like: the security of the smart grid, 'hacking critical infrastructure', monitoring and control systems. Even the data we gather with our pilot setup have turned into 'big data' that require analysis and management.

So I am actually more of an engineer than a physicist. But I am still very interested in theoretical physics as sort of a mental exercise, and I indulge in reading textbooks as hobby. In 2013 I had focussed on (re-) learning quantum field theory.

Since 2014 I am mainly blogging on down-to-earth classical mechanics or thermodynamics, and I enjoy doing cross-checks and back-of-the-envelope calculations on my blog.
