Hi, I’m the author of the relationship between the decimal system, geological time and the golden ratio on Amazon. It’s an o level or grade 6-7 mathematics and general science book for highschool students to gain a deeper more interesting understanding of mathematics. I used to be a medical student, I was in medical school for 4 years before changing my major to sports physiology (kinesiology). So, yes my major is in the biology/physiology field but I am very keen on mathematics and plan to continue to masters and doctoral level in physiology and education. I do have a distinction in pure mathematics at CAPE unit 2, A level.
