how do you learn to be a guytar?

a spark is typically hotter than 800°C while soldering above 400°C just isnt something you see for electronics. (brazing is another matter though)

here is a schematic diagram with the structure: https://www.thermaltronics.com/datasheet/M8SB276#item38791

the core of soldering irons has been copper for a long time.

it is not dangerous in any way since it is just metal and metal oxides that do not mobilize at the temps you use for soldering. it is not recommended because the protective layer on most modern soldering irons is made from iron (not steel) and iron is softer than steel.

Disruptive innovation

Das gute daran ist das so eine Disruption normalerweise gleichbedeutend ist mit mehr Auswahl und niedrigeren Preisen für Kunden, selbst wenn sich die alteingesessenen mit Klauen und Zähnen dagegen wehren.

That is standard for all rewirable connectors though.

there are still countries where hunting with lead shot is common. and there are gun nuts who think this is not a big deal, because only owls and other birds of prey die from it.

I remember reading about metamorphosis in lepidoptera ("butterflies") and how the imago ("adult") is able to react to stimuli it learned about when it was still a larvae. that might sound kind of boring in itself until you learn that during the pupal stage the nervous system of lepidoptera exists in a very "fluid" state. that knocked my idea of understanding what memory is almost all the way down to zero again.
