  Solvespace is amazing, the interface is probably the most consistent among any CAD program. Unfortunately volumetric operations (Union, subtraction …) are kind of buggy sometimes.

  I was just trying to make an argument that imaginary numbers were technically not necessary and thus it makes historical sense that they werent seen as something ‘real’. Im not trying to get people to stop using them ;)

  I said that any calculation in electrodynamics CAN be done without imaginary numbers, I never said that it would be the most common or convenient way of doing things.

  If you use a different form of solution to maxwells equations, electrical impedance can totally be expressed as just another real property. Fourier transform also is not necessary to solve maxwells equations or any other physical systems. It just might make it significantly easier and more convenient.

  Obviously imaginary numbers existed and where used way before quantum mechanics was a thing but they werent technically necessary in physics because they never appeared in the equations of fundamental theories (Maxwells equations, general relativity, newtonian mechanics)

  Up to the introduction of quantum mechanics imaginary numbers where only ever a theoretical tool and any calculation in electromagnetism, mechanics or even relativity can be done without them.

  Also, any measurement you can make will always result in real numbers because there is no logical interpretation for imaginary measurements (a speed of 2+i m/s doesnt really make sense)

  Honestly I cant live without UBlock Origin after using it for so long. The modern web is so horrible with ads

  That is why lemmy is decentralized, no one can buy every single instance. and even when a corporation buys the codebase of lemmy, another person can come in and create their own platform that is still compatible
