Blackboards with mathematics or physics formulae can be considered many times as art pieces.
You can often find blackboards which are amazing and inspiring from an artistic point of view if you look both at the conceptual content the teacher put in them and at the graphical execution.
A unique feature of a blackboard drawing is its immediacy, meaning that it’s usually created as the thought process and its explanation unfold.
I like so much these blackboards (or whiteboards or flipcharts) with scientific content.
If you too like this kind of drawings take pics and share images or videos of blackboards, wherever you can find them.
Most importantly, add a comment on why you like this particular blackboard drawing and which emotions it provokes in you.
Please put in the comment also a short description of the content, the situation in which it was created (e.g. lesson or meeting or whatever), its author, place and date.
I post a blackboard (courtesy by Alejandro Guijarro) taken at a Quantum Physics Department. You see a substrate of physics formulae and over many layers of different content. The result is amazing for me.
