Carl Sagan is a major reason why this blog exists. I've been into science as a kid, but I always envisioned it as a niche, nerdy thing. Carl Sagan showed me that science can be mainstream and cool because it affects everything around is, every day! He directly inspires my #ScienceLooksGood hashtag.
Check out this amazing video from Sagan's audiobook for Pale Blue Dot. Sagan describes how humbling it is that the earth is nothing more than a pale blue dot in the vast openness of a much larger universe that we have yet to understand. If you can't see the video embed below, click here.
Happy birthday, Carl.
