Behold, close-ups of the sand from around the cosmos
Think you've seen sand? You haven't seen sand.
- Microscopic photography exposes the beauty and strangeness of sand.
- Water wave action produces a startling variety of sand grains.
- That stuff between your toes is a lot more interesting than you might think.
We typically refer to grains of sand as uncountable tiny bits of rock whose most interesting characteristic is just how many of them there are. Like stars in the sky. We do them a disservice. Even the Oxford Dictionary defines them nearly as "A loose granular substance, typically pale yellowish brown…"
Scientist, author, teacher and photographer Gary Greenberg knows better. This doctor of developmental biology invents and patents high-definition, three-dimensional light microscopes. He's the founder of Edge-3D, for which he develops innovative 3D imaging devices — some of his technology is currently in use on the International Space Station.
Since 2011, Greenberg's been photographing everyday objects whose beauty and complexity is revealed only when they're magnified. His photographs of sand reveal a world of fascinating shapes and colors which we had no idea existed. High-quality prints of his images are available for sale on his website.
Greenberg explains what we see in each of photo. (We've edited his text slightly.)
This image is a handful of sand grains selected from a beach in Maui and arranged onto a black background. The colors and shapes of these tiny grains of sand are surprisingly different and astonishingly beautiful, each with its own individual character.
#2. Hamoa sponge spicule
Elegant beauty in a sponge spicule fragment from a glassy sponge found in sand from Hamoa Beach, Maui, Hawaii.
3. Okinawa, Japan puffy stars
These are star-shaped, calcium carbonate shells, or "tests," produced by tiny forams, single-celled ocean organisms. Cute sand grains?
4. Lunar sand
Apollo 17 astronauts discovered this "orange soil" on the rim of Shorty Crater in the Taurus Littrow Valley. These tiny, glassy orange spherules originate from a fire-fountain volcano that erupted over 3.8 billion years ago.
5. Plum Island garnet grains
These come from Plum Island, Rowley, Massachusetts, the northernmost barrier island in the United States. Its beach gets its pink color from garnets in the sand. Denser than most other sand grains, they get left behind as the waves sweep less dense material away.
6. Great Bahama Bank ooids
There are three areas in the world where ooids are created from tidal currents that keep mineral grains in constant motion. This results in carbonate precipitation forming around them. One of these locations is the Great Bahama Bank — these come from Joulter Cays, located about ten miles north of Andros Island in the Bahamas.
7. Corsican sand mask
A single grain of sand from the island of Corsica, France, looks like a mask. Or an Angry Birds pig snout.
8. Sand from South Point, Hawaii
These grains are from South Point on the Big Island of Hawaii. The translucent green grains are olivine — at South Point on Mauna Loa's southwest rift, the pounding surf erodes a forty-nine-thousand-year-old volcanic cinder cone made of olivine. The deep-red grain (upper left) is volcanic rock.
9. A tiny sapphire in Japanese sand
There appears to be sapphire crystal in this sand from Japan. Who knows what you'll find under your feet if you look?
Setting a simple intention and coming prepared can help you — and those around you — win big.
- Setting an intention doesn't have to be complicated, and it can make a great difference when you're hoping for a specific outcome.
- When comedian Pete Holmes is preparing to record an episode of his podcast, "You Made it Weird with Pete Holmes," he takes 15 seconds to check in with himself. This way, he's primed with his own material and can help guests feel safe and comfortable to share theirs, as well.
- Taking time to visualize your goal for whatever you've set out to do can help you, your colleagues, and your projects succeed.
Some games are just for fun, others are for thought provoking statements on life, the universe, and everything.
- Video games are often dismissed as fun distractions, but some of them dive into deep issues.
- Through their interactive play elements, these games approach big issues intelligently and leave you both entertained and enlightened.
- These five games are certainly not the only games that cover these topics or do so well, but are a great starting point for somebody who wants to play something thought provoking.
How do we combat the roots of these hateful forces?
- American Psychological Association sees a dubious and weak link between mental illness and mass shootings.
- Center for the study of Hate and Extremism has found preliminary evidence that political discourse is tied to hate crimes.
- Access to guns and violent history is still the number one statistically significant figure that predicts gun violence.
