There are different levels of understanding.

I’m trained in physical sciences. I studied at university and then worked ~8 years for a research department and at one point learned 2D NMR and how to run molecular simulations on a supercomputer. I’m well aware of the challenges of winning grants against colleagues and getting papers published and surviving peer review and then hoping your work gets noticed outside your of weird little niche.

My buddy is a schoolteacher. He can run circles around me with arithmetic and explain the scientific method in rap format so kids eat it up.

We’re both ostensibly working with the same core principles but the reality ends up quite different. Context matters.
