Via James Nicoll, a post he describes as “someone actively working in a particular field of science talk[ing] about how they went from embracing wingnuttery to more fruitful activities,” in this case regarding the “Face on Mars.”
Sadly, other than a couple of passing mentions (he name-checks Richard Hoagland and Carl Sagan, and mentions overdosing on Art Bell), there’s very little detail about that transition. And, really, I think hearing the story of how the author went from believing in a real face on Mars to taking high-resolution pictures of the Cydonia plateau would be a lot more interesting than, well, than another picture of the Cydonia plateau.
It’s a cool picture, though.
