Artists and Craftsmen In Science Writing

by Ashutosh Jogalekar There are two kinds of science writers which I will call “artists” and “craftsmen”. Since I might face the opprobrium of both groups by attaching these labels to them, and especially because the two categories may overlap considerably, let me elaborate a little. Artists are big on literary science writing; craftsmen are…
