Mercury + Sound = Kooky Mad Science Party

Now let’s watch what happens when you take a blob of mercury and subject it to different audio frequencies. Spoiler alert: the mercury forms geometric shapes and appears to dance. This is slow-motion footage (with music added, not the tones the mercury is reacting to — we’ll get to those original tones [...]

Century-old Lens Still Making Pictures

What’s so special about the photo above? Photographer Timur Civan snapped that photo using a modern digital camera with a vintage 104-year-old Wollensak lens. Back in 2010, Timur wrote: He found in a box of random parts, hidden inside anther lens this [...]

Those are sad times, but they will soon be in the past. Researchers have made progress toward interactive contact lens displays. Here’s the [...]

New "Scratched Glasses" Give Perfect Vision

Bifocals and trifocals allow people with limited vision to see objects at varying distances, but only by refocusing on the object from a different vantage. A scientist named Zeev Zalevsky responded to this problem by developing a lens that allows the user to focus on any distance out from 33 centimeters: It involves engraving the surface [...]

Eye Augmentation in the Future

Parviz, a bionanotechnologist at the University of Washington, writes that in the future, biotech innovations could lead to display screens inside contact lenses: These visions (if I may) might seem far-fetched, but a contact lens with simple built-in electronics is already within reach; in fact, my students and I are already producing [...]
