Not all snowflakes are unique in their shape. There's one fact for you.

And here's another: The shape of snowflakes — whether individually distinct or mass-production common — is determined by chemistry. Specifically, the shape is a function of the temperatures and meteorological conditions the snowflakes are exposed to as they form and the way those factors affect the growth of ice crystals.

This short video from Bytesize Science will give you a nice overview of snowflake production and will help you understand why some snowflakes are unique, and why others aren't.

The Underwater Project (5)

The photograph above is absolutely amazing! It is part of “The Underwater Project” by Mark Tipple.

Notes from the artist: [1]

10 years ago after high school I spent a few years traveling around Australia in an old station wagon filming surfing, clutching to dreams of making it in the surf film industry that would facilitate my future of cruising around the world to exotic beaches filming perfect waves. While the surfing and conditions were what I wanted to be filming, the images always left me wanting more. After trying countless experiments of camera positions (helmet camera, board camera) and different places to film while in the water (pole extensions, different lenses), I still couldn’t capture what I was seeing in my mind.

Fast forward to 2009 and after directing a film in Mexico on Shark Divers I had an underwater camera which we used to get closer to the sharks than our larger cameras physically could, upon returning to Sydney I started shooting surfing again, however this time from below. A month later I was shooting a small shorebreak and was caught inside by a large set, as I dove under I noticed a group of kids next to me. I turned the camera onto them and shot them as they contorted and struggled to avoid the wave above; surfacing I glanced at the lcd screen and the first Underwater Project image was there. Entitled ‘Escape’, to this day it’s as close to the images that I was chasing a decade ago. Soon after I traveled to remote beaches in the South Australian desert with a good friend to work on the idea further; after 6 hours in the water we ended up with 4 images that made it to the final selection, a solid start to the series.

A dock that once floated in Medina Lake hangs by wires on the side of the rocky bank.

The banks of Tiki Island in the middle of Medina Lake, Texas, are exposed, Jan. 19, 2012, due to receding water levels. The lake is 52 feet down. It has not been this low in more than two decades, and the lake is expected to continue to lose a few inches every day as the 15-month drought continues.
