Context: I'm researching a new book on ordinary differential equations through various real-world simulations, so like an ODEs theory book, but actually applying the concepts to real world systems. Get in touch by email if you're interested in seeing advanced preview of some of the projects that will be developed this summer. Contact info in profile.
