The passage around this formula
In 1971, Leon Chua published “Memristor — The Missing Circuit Element” in IEEE Transactions on Circuit Theory . His argument was one of pure symmetry, not empirical discovery. Circuit theory recognizes four fundamental variables — charge, current, voltage, and magnetic flux linkage — and, in 1971, three of the six possible pairwise relationships among them were already embodied in named components: the resistor relates voltage and current, the capacitor relates charge and voltage, the inductor relates flux linkage and current. Chua noticed that the sixth relationship, between charge and flux linkage, had no corresponding physical device, and reasoned from the completeness of the other five…
