For the anniversary of the Department of Geology and Exploration of Mineral Deposits a presentation was prepared about the activity of the geologist V.S. Sobolev and his main work - prediction of a diamond deposit in Yakutia, carried out on the basis of comparison of the geological structure of diamond-bearing provinces of South Africa and Western Siberia. This can serve as a vivid example of successful use of mathematical model in geology. Material about the life and work of a scientist is combined with a story about mathematical models and the most common example of the use of a mathematical model (the discovery of the planet Neptune) most expressively reproduced in the program PowerPoint. The material is organized on 13 slides, which run automatically, so it looks like a movie. The presentation is accompanied by audio and video and lasts 8 minutes.
