Scientific investigations in school using technology.
Investigations, sometimes related to IAs and EEs
Math
- 2019-06-08 Battle Royale in Matlab A simulation of several ‘battle royale’ contestants, calculated in Matlab using the ODE (Ordinary Differetial Equations) solver. The student later explored diffusion as the second derivative to model the behaviour.
- 2019-12-12 Bifurcation in Mathematica Having played with the chaotic behaviour of these functions in the early 90s of the last century on my Atari ST it was great to see them simulated in Mathematica. So I tried this on the free Mathematica 12.0 on my new Raspberry Pi 4.

- 2018-10-10 Resonance frequency and related impedance of loudspeakers
- 2018-10-10 Force over travel for a keyboard, like the butterfly mechanism on MacBooks.
Chemistry

ESS
- 2020-12-04 To what extent does the implementation of glass buildings increase the release of CO2 into the environment?
