Please see below the presentation slides that I originally intended to use in the lecture on wood modification on March 19th 2020. I added a few more lines here and there so that it can be understood more easily. Furthermore, there are some short videos on some key aspects and I marked the passages in the lecture slides where it makes most sense to watch them. The lecturer in the videos is Prof. Callum Hill, who is an expert in the field and also the author of the book "Wood Modification".
