"…I never was someone who could stop asking “why?”" When a kid of about four I found a pair of WWII headphones and took them to my father who pulled out the iron diaphragm and showed me magnetism at work—somehow some magical force was pulling the diaphragm back into the headphone with seemingly nothing in between. Absolutely fascinated, I wanted to know what this invisible 'magic' was. Many decades later every time I look at my fridge magnets I still ask the same question and I don't believe I'm much closer to the truth! Sure, there are the simple answers everyone's taught, then there's QFT but even that doesn't tell me exactly what's going on. And why does alpha have the value it does, and why exactly does c = 1/(μ0ε0)^1/2? Not knowing and not being able to figure these questions out is, at times, infuriating. For me, solace of sorts can be found in engineering—I can build an electronic circuit and end up with a tangible working device. On the way I'll curse my electrons for making so much noise that they sound like ball bearings rattling around in an empty oil drum but I'll eventually calm down and apply Johnson–Nyquist to shut them up (well, a little bit anyway). |

I got sucked into the infinite perspective vortex from the cosmology angle - a grandmother with a vast collection of pulp sci fi and clear skies over her canal boat. And yes, magnets, what is this devilry and why will nobody tell me how it works?
Upon discovering said imponderables I moved to the woods instead - building infrastructure of all varieties from the ground up, playing with hydropower, that sort of thing - and of course EE gets jammed in all over the place, and when I can get away with something simple and analogue, I do.
I build things because the alternative is spending tracts of time staring into the abyssal fact that explanation is always ultimately internal to the system being explained.
