Gleichen's microscope. (source: Wellcome on Wikimedia Commons) Manu Prakash, a bioengineering professor at Stanford University, talks about radically inexpensive microscopes and the democratization of discovery in this episode of the Hardware Podcast. Prakash’s Foldscope is a “completely functional, foldable, origami microscope.” He says that “every kid in the world should carry a microscope in their pocket,” and so far, more than 50,000 Foldscopes (the parts of which cost only $1) have been shipped to more than 130 countries.
You’ll hear the “audio demo” of Foldscape that Prakash gave us, explaining the instrument’s paper, circuit board, and lens, plus the philosophy behind his mission to promote curiosity-driven observation and “make microscopy a dinner conversation.”
