Before humanity managed to send man-made objects into space seventy-five years ago, the field of orbital mechanics didn’t really exist. Only the movements of other celestial bodies mattered. Things have really changed since then.
Dutch high school education has always been pretty good at teaching the basics of science. I also have a master’s degree in computer science from what is considered one of the top universities in the Netherlands.
That has given me a strong basis in math, physics, some chemistry, and of course, IT.
I like to keep that knowledge up-to-date and expand it by looking at certain interesting scientific phenomena. And for me, writing is learning.
