math
{
Linear Algebra : I know how to multiply a matrix, i know what a dot product, cross product is
(off the top of my head concepts that i can recall):
> cross product you get the normal to a surface
> dot product is a projection
Complex Analysis : This is the area of math i find most interesting and where i left off on my math pursuing journey
(off the top of my head concepts that i can recall):
> mult by i is 90 deg transform
> De Moivers: mult of complex numbers is addition of angle
Multivariable Calculus : conceptual understanding is there for gradients, partial derivs but im not practiced if you ask me to integrate i cant
(i had a pet project of writting backgprop in C so i that was my way of trying to get the concepts)

.ie I am my work,
so in my current job I've found when working within,
an old messy legacy patched up codebase i struggle to be at peace,
there exists an inate urge to clean it up and this doesn't always go over well with management
