Want to make sure you back something up indefinitely? Then you could do worse than a digital data storage technique that uses laser light to store 360 terabytes of information on nanostructured quartz for up to 14 billion years.
Many have savored the arresting visual beauty of Raphael’s “Madonna del Prato” (1505). Now you can listen to it as well, thanks to a new series by Athens-based artist and physicist Yiannis Kranidiotis, who transformed this and other classic paintings into haunting digital soundscapes.
I bet you’ve never thought about how giant clams will revolutionize future technology. It’s okay. You probably didn’t know about the incredible way these massive mollusks turn sunlight into power.
Human wetware is astonishingly good at pattern recognition and interpreting complex, noisy data, but it’s also painfully buggy. Mars is the red planet, except it really isn’t.
This extraordinary image of an apparent floating city has created a stir among conspiracy theorists, but a well-known optical illusion is the likely explanation for the phenomenon.
A camera obscura and camera lucida work using different principles, but they both make use of mirrors to let us see the world in a different way. The camera lucida used to be a favorite tool of artists and amateur sketchers, because it lets people trace an image directly onto a page.
Popular answers to this question included “silver,” “white,” “whatever color it’s reflecting,” and “no color at all.” But most mirrors are actually very faintly green. Yes, green.
Something you put in your drinks has a special property that, along with special polarization, causes it to erupt into rainbows. Find out what it is, and what makes it so colorful.
A research team from Harvard University has made pig-skin lasers. Here’s how they did it—and perhaps more importantly, why.
So, that Internet apocalypse that’s going to befall us when our fiber optic cables max out? Maybe not so much. On Thursday, engineers reported in Science that they’d broken the “capacity limit” for fiber optic transmission, opening the door to future networks that carry more data further at lower costs.
If you’re a non-magical being, you might think your chances of becoming invisible are slim to nil. But don’t jump to conclusions just yet: Researchers are now claiming to have developed a portable system that can make small objects, like your keys or pet lizard, disappear from sight.
The newest high-speed camera on the block won’t be making its way into Michael Bay’s hands anytime soon, but it will be making his ‘splosions look rather poky. See, this camera will be helping scientists watch atoms zoom around at 28,000 miles-per-second.
Nearsightedness is reaching epidemic levels worldwide, but nowhere is its rise more prevalent than East Asia, where as many as 90% of teenagers and young adults now suffer from blurry distance vision. Why the sudden spike? Book work has long been blamed, but recent findings point to something else.
If you've seen a solar eclipse, you know that just before the sun is hidden from view something very strange happens. Shadows start swirling, as if the light from the sun is shining through a heat haze. The phenomenon is called "shadow bands."
Many people know that diamond is actually pretty common when it comes to gemstones (you can find millions of them in your typical candle flame), but who among us can actually name any that are rarer? Here, we present to you a collection of ten of the rarest gemstones on Earth.
You know it's going to be a good night when a telescope fires a laser guide star straight into the heart of the Milky Way.
What do a butterfly's shimmering wings, a fish's opalescent scales, and a peacock's brilliant feathers have in common? Yes, their colors are beautifully iridescent. But they are also produced by the physical interaction of light with sophisticated nanoscale architecture that we are only just beginning to understand.
Under the right conditions, the upper edge of the setting sun will blaze bright green just before dipping below the horizon. What causes these "green flashes"? The answer is more complicated than you probably realize.
