Open figure 001Electric-field topology
A visual language inspired by device simulation: structure, field, signal and the notes between them.
Notebook principle
“Science becomes more useful when the process—not only the polished result—is made visible.”
This space connects research, simulations, teaching, software, stories and scientific exploration in one evolving record.
