My condolences.

You guys are using windows?

The natural representation would be the transient solution u(t) or i(t). Harmonic solutions are merely a special case, for which it turned out complex numbers were useful (because of the way they can represent rotation). They certainly serve a purpose there, but imo this is not an instance of ‘complex numbers appearing in nature’.

But that is hardly a ‘natural occurence’ of complex numbers - it just turned out that they were useful to represent the special case of harmonic solutions because of their relationship with trig functions.

Julia?

or just install and then shut down?

Hardware that lasts forever? Great idea! Just make it as sturdy and user-repairable as possible, and there’s no need for a subscription
