Nature Knows: Amazing macro-photography of individual snowflakes [10 Pictures] Photographer Alexey Kljatov takes incredible close-up photos of snowflakes in his backyard in Moscow. "I capture snowflakes on the open balcony of my house, mostly on glass surface, lighted by an LED flashlight from the opposite side of the glass, and sometimes in natural light, using dark woolen fabrics as background."

11 Stephen Hawking Quotes for His 71st Birthday When Stephen Hawking was diagnosed with motor neurone disease at age 21, doctors thought he'd only survive a few more years. But the theoretical physicist defied the odds: Hawking turns 71 today. Here are 11 quotes from the Director of Research at the Centre for Theoretical Cosmology at Cambridge and author of A Brief History of Time. Happy birthday, professor! 1. "At school, I was never more than about halfway up the class. From the lecture "My Brief History," 2010. 2. "If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans. From Into the Universe with Stephen Hawking, 2010. 3. “I wouldn’t compare it to sex, but it lasts longer.” From a lecture at Arizona State University, April 2011. 4. "If you are disabled, it is probably not your fault, but it is no good blaming the world or expecting it to take pity on you. From "Handicapped People and Science," Science Digest 92, No. 9, September 1984. 5. 6. 7. 8. 9. 10.
FlowingData | Data Visualization, Infographics, and Statistics MASSIVE VOODOO: Tutorial - Zenithal Lightning / Work Order posted by roman, jarhead, kong Aloa. This time i want to talk about light. I will also do italic side notes while talking about light to give an overview on my personal painting order. Talking about light sources There is for sure one light source that will influance your models everytime you look at them. Dramatic Light situations can often be found in Artist paintings - this is always a good inspiration to learn from. Or this one, found here: Raffaele, our beloved Chapuchin, already wrote this great article about light in common. Now i will get one step deeper into detail light painting as there is one light source, which can make your painting a real joy when you get to understand it. Zenithal lighting theoryMeans an imagined light source, unreal first - up to you to make it real and alive hitting from the top at the miniature. Why from the top? Next i let Zenithal Lighting hit the model. Keep on happy painting!

Below, we explore our favorite 15 chemistry GIFs and the science behind them (when we could figure it out): Melting Metal With Magnets The Science: The copper wire has a significant amount of AC electricity running through it, causing it to act like a really strong electromagnet. In the metal slug, eddy currents form due to the magnetic field the copper wire is causing while the copper wire has high frequency AC flowing through it. The metal slug’s electric resistance causes a portion of the electric energy to turn into heat, but the heat builds up until the metal slug becomes white hot and melts. Orange LED Light In Liquid Nitrogen The Science: When an LED is immersed in liquid nitrogen, the electrons lose a lot of thermal energy, even when the light isn’t turned on.

Acoustic Levitation Is Science's Coolest Phenomenon Acoustic levitation, a method of using sound waves to suspend small particles, is one of coolest phenomenons in science. Japanese scientists Yoichi Ochiai, Jun Rekimoto and Takayuki Hoshi have released footage of their new series of acoustic levitation experiments that demonstrate the power of noise. Image: Mashable The clip provides a quick and simple overview of the team's work before getting into some mind-bending levitation experiments with small items like nails, bolts, wood pieces and even drops of liquid. It's a neat look at a wonder that fascinates both scientists and geeks alike. Have something to add to this story? Image: YouTube, 落合陽一
