After finding out that
Intel 4004 was not the first microprocessor, now this, transistor 25 years before the transistor:
Losev conducted some of the earliest research into semiconductors, publishing 43 papers and receiving 16 "author's certificates" (the Soviet version of patents) for his discoveries. He observed light emission from carborundum point-contact junctions, constructing a light-emitting diode (LED), did the first research on them, proposed the first correct theory of how they worked, and used them in practical applications such as electroluminescence. He explored negative resistance in semiconductor junctions, and was first to use them practically for amplification, building the first solid-state amplifiers, electronic oscillators, and superheterodyne radio receivers, 25 years before the invention of the transistor.

Yes, that's exactly why I think it can be done with analog (AC) computing and no zombie cats thank you!

Same idea (of building a symmetric circuit then measure the symmetry of its waveform by looking at the second harmonic) should work to pair any other type of non linear components, too.
I think Shatner is going to out live the rest of them.

The fuel consumption of a car is 5 liters / 100km.
1L == 0.001m
3100km == 100 000m
1m == 1 000mm
5L/100km == 5*0.001m
3/100000m == 0.05x10
-6m
2 == 0.05(mm)
2so the fuel consumption of that car is fifty mili square-milimeters.
