>>14274472>>14274400analog computers are physical implementations of differential equations. Using node-voltage analysis, operational amplifiers, resistors, capacitors, and inductors, a specific node (or nodes if it's a system of differential equations) can be created such that the voltage with respect to some other node is an exact (save for component nonidealities) manifestation of a specific differential equation. Thus, the equation has effectively been solved without ever having to manipulate the differential equation itself. All that's required is measuring the voltage. This is what's meant by "can solve equations fast" because the voltage is inherently the solution and its propagation is near instantaneous. It doesn't stop brainlets with no understanding from thinking they're some sort of obscure miracle though; a lot like the same brainlets thinking FPGAs are super duper microcontrollers.
analog computers suck for millions of reasons and digital methods have overtaken them in practically every domain. The only place they really have parity is in analog music synthesizers and effects, and even then, anyone who's ever worked with them can tell you just how limited they are.
