“look for what’s detectable..”

A fun and fascinating talk by physicist Freeman Dyson from 2003 begins with George Washington at Princeton, and grow-your-own-cat [or dog] biotechnology kits, before moving on to astronomy. Specifically the possibility of life on the Galilean moons of Jupiter, and further afield – such as the newly named plutoid dwarf planet Makemake with its surface of frozen methane – rather than say.. Mars.. Via TEDtv, via the Professor.
