first release (#1)

* add main structure

* add coriolis, thermo and quanten

* add Brechung

* begin Linsen

* Add schwingungen diagram and Bewegungen

* Update Physik.tex

* Add Hydromechanik and complete Linsen

* update font

* add Kraft Energie Impuls

* add Schwingung and Wellen

* some formatting

* formatting

* small changes

* fix typo in Linsen

* fix typo in Wellen

* fix typo in Harmonische Schwingung

* Change authors

* Update Physik.tex

I would suggest removing the 'emphbox' and replacing it with Textcolor where we find the formulas necessarily important. In my opinion,  we can highlight other formulas as well, without only focusing on those 4 formulas. Otherwise, we can box the formulas that we find important, but then maybe other ones. At the first glance, I can just focus on those 'emphboxes' since they are really visually highlighted. It could act as an advantage as well as the opposite. Let me know what you think.

* remove emphbox

* Change email - remove textcolor
