Clownian Motion

Authored by @zbwrm (Aydin O'Leary) and @mmadanguit (Marion Madanguit).

Python script that models Brownian motion of particles and hopefully, eventually, colloidal glass transitions.

Structure

• particles.py - performs all particle simulation calculations.
• data.csv - contains data output of simulation.
• plot_collisions.py - outputs animated simulation of the particles moving over time.
• plot_MSD.py - outputs plot of the particles' mean square displacement over time.
• plots - contains example outputs of plot_collisions.py and plot_MSD.py

Setup

1. Clone the repository.
2. Run python -m venv venv and source venv/bin/activate to set up and activate a virtual environment.
3. Run pip install -r requirements.txt to install the dependencies.

Run

1. Run python particles.py to run our simulation.
2. Run python particles.py > data.csv to save the output of the simulation to a file called data.csv.
3. Run python plot_collisions.py to see an animated simulation of the particles moving over time.
4. Run python plot_MSD.py to see a plot of the particles' mean square displacement over time.

Note: All plots open in a separate browser window.

Results
