## All It Took Was An AHA!

I can clearly recall why I became a computer scientist. I was sitting in a class and we were discussing how cons was implemented. And then I saw this definition:

 1 2 3 4 5 6 7 8 9 (define (cons a b) (lambda (x) (if (= x 1) a b))) (define (first l) (l 1)) (define (rest l) (l 2)) 

The lambda calculus and the material in the little schemer kept me in the field (computer-science i.e.) and assured me that there would never be a dearth of aha! moments in my education.

Good educators can deliver such aha! moments in every single lecture. A good textbook can do it several times each chapter.

I have since tried to find material that delivers such aha! moments.

Hopefully, I will encounter them for the rest of my life in whatever I do.
