File talk:Chalkboard LG Equations DIFF.png

Makes me wonder if the artists actually even touched a real chalkboard in their life.

YOU try drawing anything with chalk and see how unlikely it is someone would bother to draw such a detailed thing there  (in chalk) rather than on paper

Likewise the equations better be alot further along than still having them on a chalkboard if some important machine is to be built allegedly using them (whatever those really are  - as employing 'quantum' physics in a mechanism  is alot more complicated than some theory (hypothesis rather)  equations.
