I wanted to add my own short appreciation of his work; Cosmos was one of the first hardback books I bought myself that wasn’t a textbook; The Dragons of Eden was another early addition to my library.
My first scientific love as a child was astronomy; I moved on to chemistry when I got fascinated by what the stars and planets were made of. Reading Sagan’s work helped me recapture that early love and fascination. I’m sure his writing was pivotal in having many people decide to pursue science.
May his memory remain unwithered. Ex astris, scientia.
