Every experimental measurement in physics includes sources of noise. Of course, we try to minimize the sources of noise, but there is a limit to this ability (thermal noise, for instance, can be minimized, but not eliminated). Consequently, it often … Continue reading
(Updated 11-Jan-2022; fixed broken links and updated notebook) This started out as a way to make sure I understood the numpy array slicing methods, and builds on my previous post about using scipy to fit data. I define a 3 parameter … Continue reading
Here’s a common thing scientists need to do, and it’s easy to accomplish in python. Suppose that you have a data set consisting of temperature vs time data for the cooling of a cup of coffee. We’ll start by importing … Continue reading
I’m working on a text on computational physics whose primary goal is to create something useful for a one semester introductory course that all our physics majors (and now chemistry majors too) will be required to take. I want students … Continue reading
Here’s a nice link to a pdf file with a summary of matlab, NumPy, and R commands.Very handy for people like me that cannot remember all the various commands one needs to get something done. Also, if you haven’t tried … Continue reading
