To be quite honest this soured my early differential equations class. We were just finishing the first module which is all about random substitutions and how that works but then the second module was a transition from that to a more qualitative approach to studying solutions of differential equations and obviously I was excited by then BAM

>For the next few classes we are going to look at applications. Look at these physics equations. Now, look at these statistics equations. Great job.

And it was so fucking boring. To be quite honest the only thing I learned is that it must suck dick to be a physicist or statistician and have to actually care about those trivial disgusting differential equations that even a retard could solve.

Education is fucked up. You should start with the real world application and then move onto theory. Elon Musk is working on a new school model I believe where we teach things in the context of application and never just lecture people on shit like calculus in the abstract sense.
