If you did not attend a university then where did you learn physics, calculus and probability? Did you have time to work full time and learn these things? Are you telling me you taught yourself those things? If so, my hats of to you bud. Call yourself anything you want. I personally think this story is fishy.
Well it is simply the truth.
There’s these things called books. Couple those with the desire to learn and you can learn anything you like assuming you have the mental capacity to learn it.
I find it amazing your views are so narrow.
