The Lecture That Sparked A Career
- Rodolphe recalls a thermodynamics lecture that ignited his passion for research when the professor's excitement filled the room.
- He credits that accidental resonance as a pivotal event that steered him toward control theory and teaching-research fusion.
Mixed Feedback Unifies Analog And Digital
- Mixed feedback combines negative feedback (regulation) and positive feedback (switching) and explains events like neural spikes.
- Treating systems as mixed-feedback amplifiers unites cybernetics, neuroscience, and event-based engineering.
Spikes As Mixed-Feedback Events
- Hodgkin-Huxley explains spikes via attaching positive and negative feedback current sources to an RC circuit.
- Thresholds arise from mixed feedback, turning disturbances above a level into communicable events (spikes).
