Ion potentials are electricity… That’s the same thing as a voltage measurement: a difference in ion charge between two areas. Open the gate and the charge diffuses. That’s a wire.
Edit: poor phrasing with use of the word “wire”, I meant in a sense that it’s moving electricity, not that it’s a conventional solid wire with flowing electrons.
See the other comments about lambdas vs. lambda calculus, but lambdas are supposed to be for incredibly simple tasks that don’t need a full function definition, things that could be done in a line or two, like simple comparisons or calling another function. This is most useful for abstractions like list filtering, mapping, folding/reducing, etc. where you usually don’t need a very advanced function call.
I was always taught in classes that if your lambda needs more than just the return statement, it should probably be its own function.
There is a bot (recently started posting) but it seems to be missing a few of the discussion threads (this and bleach both came to my mind)
I’m not arguing that it’s the same as a conventional wire, but it is definitely still electricity. Communicating a signal by difference in ionic charge is, by definition, an electric signal, even if it’s the movement of ions in a pump instead of electrons across a solid wire.
