Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

However, it is an inherently inefficient language and performing extensive numerical calculations in pure Python can be very slow. Fortunately, the NumPy and SciPy modules are a popular and effective ...

This is actually the definition of the integral in calculus—but I will save that for another day. Instead we will do a numerical calculation by simply adding up the area of a bunch of rectangles.
