Title: Having an IT background, I thought I understand fairly complex topics (FFT, sorting algorithms, calculus), but in a moment of reflection I realised that I either don&#x27;t (eg. I tried to explain them and failed) or they are fairly simple (eg. I tried to explain them and was done in 5 minutes). I asked a friend this question and he replied &quot;women&quot; (I call BS on that one :-). Which is the most complex concept you understand?
