I remember doing a lot on complex numbers in high school, but never to the point where we were told any real-world applications... do you know what physicysts or engineers use them for every day? I don't know much about these fields but I can't imagine wave functions help us build bridges?

There was some weird way of expressing complex numbers which had a real compnent... like sin(x)+icos(x)? or some such... good old days!

I'm just starting out but feel free to check out my page here too! Havn't posted much STEM yet but there will be more to come :)
