This short (10-minute) TED talk really made me gape. Biologist and scientific illustrator, Drew Berry, explains that we have no ways to directly observe molecules and what they do. At TEDxSydney he showed his scientifically accurate (and entertaining!) animations that help researchers see unseeable processes within our own cells.
The power of illustration and visualization to unlock scientific mysteries reminded me of Bang Wong’s talk on the subject, and is adeptly shown here.
