D&D character Jan Kozak, scientist/historian turned wizard

At age 70 he's on a pilgrimage to Candlekeep.⠀⠀⠀⠀⠀⠀⠀⠀⠀
It's interesting to think about the kinds of science that would exist within the confines of vanilla D&D. Astronomy, agriculture, and proto-chemistry and physics certainly would exist. What do y'all think?⠀⠀⠀⠀⠀⠀⠀⠀⠀
I can draw your character too, DM me for rates!
