The following are some of my best posts about numerical calculations.

- Time is up. There are no more excuses to leave numerical calculations out of introductory physics classes – here is why.
- How do students adjust to using numerical calculations in a physics course? Here is a summary of student opinions about coding.
- What exactly is a numerical calculation anyway? It’s the process of breaking a problem into many smaller problems. Here is an older overview with an example of a mass on a spring.
- My interview with trinket.io – sloppy code is good.
- How do you teach numerical calculations (python) to high school teachers? Here are some details on one of my workshops.
- This is not a numerical calculation, but once you start using python you can see how functions change. Here is an example of the forces needed to hold a block against a wall at different angles.
- Numerical calculations let human solve problems that could not otherwise be solved. My favorite example is the Three Body Problem.
- What about the motion of an object falling with air resistance? It’s not impossible to calculate on paper – but it’s much easier with python.
- Another example – a curving soccer ball modeled with python.
- Modeling a sagging cable as a series of masses connected by springs.
- Why are planets spherical? Modeling planet formation with a bunch of smaller masses.
- Random walks in 1D, 2D, 3D, and 4D.
- Modeling the light reflecting off a mirror with Fermat’s Principle and python.
- Modeling the motion of a falling spacecraft (with air drag) – Tiangong-1.
- Numerical solution to the Brachistochrone problem.
- Pendulums are actually more complicated than you thought – here are three ways (with python) to model the motion.
- Determining the speed of light by looking at the moons of Jupiter – modeled with python.
- Calculating and visualizing electric field vectors with Vpython.
- Using functions to find the maximum range of a projectile.
- Electric field due to a charge distribution with numerical calculations.
- Numerical calculations for energy levels of a particle in a box (quantum mechanics) using the shooting method.
- How long does it take a pencil to tip over?
- Numerical calculations for Gauss’s Law and a cube. Here is the trinket code for the Guass’s Law cube.
- How would Thor punch The Hulk? Modeling collisions with python.
- Numerical calculations for mere mortals. This is the stuff I use for my intro (algebra-based) physics courses. It’s an online “book” that starts off with simple 1D stuff.
- Python Tutorials – for calc-based physics. This is a bit more advanced python stuff – but again it’s an online “book” with code right in it.
- I started making stuff for advanced physics – but didn’t finish.
- Finally, I attempted to make a large online book with coding from the beginning. It’s not finished and I need to rethink some parts – but it’s here.
