Interlude to check out the Foldscope, a very cool project that has been getting some press around the Internets lately. Spoiler alert: It is a microscope made from cardboard!….Now that you are interested, you can take a moment to enjoy the inventor’s TED talk (a few years old but so worth watching!).
Per the Foldscope website:
Foldscope is an origami-based print-and-fold optical microscope that can be assembled from a flat sheet of paper. Although it costs less than a dollar in parts, it can provide over 2,000X magnification with sub-micron resolution (800nm), weighs less than two nickels (8.8 g), is small enough to fit in a pocket (70 × 20 × 2 mm3), requires no external power, and can survive being dropped from a 3-story building or stepped on by a person. Its minimalistic, scalable design is inherently application-specific instead of general-purpose gearing towards applications in global health, field based citizen science and K12-science education.
