Disclaimer: Numerical results obtained during some finite difference experiments (1.2.1. and 1.2.2.) turned out to be erroneous due to hardware problems (now sorted). Correct results should be produced on your own computers. Comments about deviations of finite differences from tangent and adjoint results made in the video to be taken with a "grain of salt".
