Physics, Mathematics, Simulations
Regardless whether you intend to investigate an idea for a new device or to solve a technical problem, in most cases it proves helpful to first translate these ideas or problems into the language of mathematics and check them against the constraints imposed by the known laws of physics.
This process transforms technical issues into models and also helps to identify their essence.
The obtained models can then be simulated using different tools, e.g., a spreadsheet program like "LibreOffice Calc" and "Microsoft Excel" or — on the upper end of the scale — tailor-made software. It is even possible to successfully simulate complex models by just applying a spreadsheet program.
Feiner Services would like to assist you in analyzing technical ideas and problems no matter whether they concern optics, electronics, radioactivity, chemistry, mechanics or wireless power transfer.

The premise of translating problems into mathematics was implied by Galileo Galilei:
"Philosophy [i.e. physics] is written in this grand book — I mean the Universe — which stands continually open to our gaze, but it cannot be understood unless one first learns ... the language ... in which it is written. It is written in the language of mathematics, ... ."
