I can touch microprocessors, and lasers are buzzing in airwaves. It’s the same electromagnetic radiation as what we know as radio, just
at much, much higher frequencies.
But this was asked in the context of solving this problem, in the 1950s.
- pavel_lishin 2y agoSure, but trench soldiers used to build their own radios. A soldier today stationed in the middle of a war isn't likely to assemble their own laser emitter.
- anyfoo 2y agoI don’t think anybody at that time could have built a laser emitter, even. Not sure why you would want to, to solve that problem, even today. I feel like the point of my question was lost.
- Dalewyn 2y ago>I can touch microprocessors, No you can't, you're just touching the box they come in. You can touch copper cables and wires, vacuum tubes, resistors, capacitors, breadboards, and (large!) printed circuit boards among other "basic" electronic components. You can't touch microprocessors, it's even stated on the tin they are microscopic in scale; you can't touch that in any meaningful way.
- anyfoo 2y agoWe could argue about that, but let me rephrase then: What technology that you can neither touch, nor that buzzes in airwaves, could they have used to solve this problem back then?
