“Tad is a real, honest-to-goodness astrophysicist and physics teacher - meaning, he's a FAR more reliable source of scientific research than I am. He describes his Substack as aiming at the "slightly more 'advanced' lay-person or students of the fields at, say, the sophomore or junior level" - but it's so piercingly clearly written that I'd say it's open to everyone. Delightfully nerdy and filled with wonder.”

“Great coverage of intriguing scientific questions and facts, among other fun stuff.”
