  • I think it has been shown that certain plastic softeners (e.g. phatalates) cause fertility issues, some of that might be included in microplastics but plastic itself I have not seen anything (And these specific softeners can be banned and are already mostly banned in the EU).

  • I genuinely dont see the reason for a windows tablet without a stylus. Note-taking is nice with a stylus but for just holding it and watching videos or browsing a surface is honestly too unwieldly and the windows touch interface is also not great.

  • 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)

  • This argument always makes it seem like no one at the time knew these behaviours were wrong, which is obviously not true.

    There is a big difference between just staying impartial and not saying anything or being an active part of whatever discrimination/inhumaneness is happening, and the people who were actively discriminating were bad people and still are.

  • For me personally there is no open source calculator on android that even comes close to Hiper Calc Pro. Having actual expressions and physical constants makes things so much easier and makes the app better than most physical scientific calculators.
