- Curriculum Vitae
- Where I am, what I'm doing, what I've done.
- Weekly schedule
- When and where I am this term.
- MATH 1240
- Calculus 2.
- MATH 2200
- Introduction to Analysis.
- MATH 4990
- Selected Topic in Applied Mathematics.
- A LaTeX class for TRU theses
- If you're using LaTeX to typeset your Honours thesis (you are, aren't you?) then you want this.
- Richard's Stuff
- My blog, mostly about my work on audio reproduction and acoustics.
- Delaying Room Reflections: Constraints on Room Size and
- A draft of some work on the geometry of sound reflections in rooms.
- Approximating Chaotic Saddles for Delay Differential Equations
- Preprint of some recent work on numerical analysis of transient chaos in DDEs.
- Probabilistic Properties of Delay Differential Equations
- Full text of my PhD thesis.
- Chaotic transport through the solar system
- Slides from a talk I gave a few times in 2006. Also my first experiment with Prosper.
- Consonance and Dissonance
- Slides from a talk I gave on mathematics and music in 2010.
- Calculus of Variations
- Slides from a talk I gave in 2007.
- Implementation of a genetic algorithm for scheduling optimization. I've contributed some code to this project and used it to optimize the course schedule at Okanagan College and the job rotations in the laboratory at Royal Inland Hospital.
- R Project for Statistical Computing
- "R" is a high-level scripting language for numerical and graphical work, somewhat like Octave or Matlab. It's free and open source. All the images shown here were made with the help of R.
- A collection of LADSPA plugins for active loudspeaker crossover and eq.
- Miscellaneous Images
- My research often leads to interesting images. Some of these are my takes on well-known examples; some are my originals. Click the thumbnails for details and (mostly inadequate) explanations.
- Basins of attraction for a magnetic pendulum
- Some nice images of basins of attraction for a 3D pendulum suspended over magnets.
- Strange attractor for a periodically forced pendulum
- A classic. More fractal images and psychedelic animations.
- Newton's Method
- Fractals show up when Newton's method is used to find complex roots of a polynomial. Another classic.
- Basins of attraction for delay differential equations
- I've found transient chaos and fractal basins in some delay differential equations. Pretty pictures.
- An extensive mathematical reference. I use this a lot.
- The open free encyclopedia. Related articles on
- My operating system of choice.
