The Math That Connects Pluto to DNA — NOVA Next | PBS

The Math That Connects Pluto to DNA by Alex RileyAlex Riley (NOVA Next | PBS)
How a mathematical breakthrough from the 1960s now powers everything from spacecraft to cell phones.

Concurrent with the recent Pluto fly by, Alex Riley has a great popular science article on PBS that helps put the application of information theory and biology into perspective for the common person. Like a science version of “The Princess Bride”, this story has a little bit of everything that could be good and entertaining: information theory, biology, DNA, Reed-Solomon codes, fossils, interplanetary exploration, mathematics, music, genetics, computers, and even paleontology. Fans of Big History are sure to love the interconnections presented here.
