@tufan, @leonidas, @RoWin, I went over the material slides (I think you made them?) and propose a few changes with this merge request. In particular, I removed all ocurrences of
<ins>, which you used to highlight certain passages, I think? But at least on my browser it rendered very weird, so I would rather remove that.
Also, I changed the section flow which was in the form of (exemplarily for
Material System: FluidSystem ->
FluidSystem (+image) ->
What it does: expresses ...
FluidSystems expresses ... (image)
which I think is more concise and gets rid of some slides without content.
Could you have a critical look at this and merge if you agree? And/or change whatever you think is critical. I'll add a few comments in the diff to parts that require special attention.
