In this app, you can see how action potentials work by watching the action potential as it happens and adjusting the parameters. You can add drugs such as lidocaine, tetrodotoxin, and TEA to observe the effects on the action potential. You have the option to see a single action potential with a preset current injection, or a continuous option where you can manually inject current to trigger an action potential.
Learn Quaternions
Explore the abstract mathematical concept of quaternions through an interactive, visual experience. Manipulate rotation angles and axes with sliders and touch gestures to understand their behavior in a fun and engaging way.
- Visual quaternion exploration
- Interactive sliders for rotation
- 3D scene manipulation via touch
- Fun and engaging learning method
- Built with RealityKit
