%description
Show physics, math and engineering students how an ODE solver is made and
how effective R classes can be for the construction of the equations that
describe natural phenomena. Inspiration for this work comes from the book
on "Computer Simulations in Physics" by Harvey Gould, Jan Tobochnik, and
Wolfgang Christian. Book link:
