I don't tend to idolise people, but the late Carl Sagan was an inspirational yuman. He can hardly take credit for the wonders of the cosmos he so artfully detailed in speech and print, but in communicating them with essential simplicity, poetic elegance and relatable urgency, delivered in an enjoyably imitable style, the messages even got through to a trivial imbecile like me.
It's a shame his landmark TV series Cosmos (1980) wasn't part of my childhood, but I got to it in time to avoid having to settle for Brian Cox or Neil deGrasse Tyson's Sainsbury's Basics equivalents. Rest assured it's going to be at the core of my daughter's extracurricular curriculum until she's similarly devoted or sick of the guy in the turtleneck with the weird voice.
Timeless in many ways, as a time capsule viewed at increasing distance from contemporary understanding and experience it's inevitably dated in others, but this has the positive side effect of ever-expanding retro charm, especially in the sound and vision departments. It literally has everything.
