The Invisible World Revealed
We've occasionally pointed you to TED talks when the investment of seven or so minutes is worth your time. Here's one where that's surely the case. It is biomedical animator Drew Berry talking about and showing the invisible world of life at the molecular level. It's a reality we can't see because its dimensions -- DNA, for example, is 2 nanometers wide -- are smaller than the wavelength of light but whose shapes and working we infer by other means. You'll hardly find a better, more jaw-dropping animation of the cell's "astonishing molecular machines," as Berry accurately describes them, than in this very brief video.
When I say it's jaw-dropping, I mean that literally as those of us with TMJ may wish to take note.
