A workshop that explores many of the topics described on this website and in the book is offered each June. In some years the workshop is offered online and in other years at Friday Harbor Labs in the San Juan Islands of Washington State, USA. For more information, consult the workshop website by Clicking here. Then find the Course Website links (e.g., 2018 Workshop) at the bottom of the course page, choose one and then click on Schedule to find lecture topics, videos of lectures and associated notes, ppt, videos etc. In addition, a playlist of Arnold’s workshop lectures in the period 2014-2022 is available on Youtube at Lectures and talks by Stevan J Arnold. Some of the garter snake datasets and R-script used to analyze examples in the book can be downloaded from my lecture entries on the Course Website (see also Data on the header of this page).
