Almost a year to the week after an extremely rare temperature inversion caused the Grand Canyon to fill with clouds, the phenomenon happened again. The Grand Canyon National Park had cameras at the ready and shot some fantastic photos from around the canyon as well as a timelapse video. (via Neatorama)

How to Draw Mushrooms on an Oscilloscope with Sound

In this surprisingly interesting video from Jerobeam Fenderson we watch (and listen) as he explains how to draw images using the visualizations of sound waves on an old analog Tektronix oscilloscope. To be clear: the images you’re seeing here are not being animated through software, instead Fenderson creates waveforms (sounds) using his computer, and those sound waves LOOK LIKE THIS when fed into an oscilloscope. Suffice to say there’s lots of math involved, and it’s all a little bit over my head, but luckily he answers some questions over on his blog about how it all works. Make sure to watch through to the end.

The AmazingScience YouTube channel demonstrates how to build a ridiculously simple electric “train” with the help of a few magnets, a battery, and a copper coil. You can also use the same materials to build a little spinning motor-like contraption. (via Twisted Sifter)

With a host of audio-based science experiments from sine waves blasting through streams of water, to visualizations of audio frequencies using sand, and sound waves traveling through flammable gas, this new video by Nigel Stanford has it all. Titled Cymatics, the music video was created for the first single from his new album, Solar Echoes. If you want to learn more about the science, there’s plenty of behind-the-scenes footage with explanation behind each experiment on his Vimeo channel. (via Vimeo Staff Picks)

HD Timelapse of the Sun Captures Largest Sunspot in 22 Years

November 10, 2014

Christopher Jobson

The Solar Dynamics Observatory just released this amazing timelapse created from 17,000 images of the sun taken late last month. The bright spot you see gradually passing from right to left is sunspot AR 2192, the largest observed sunspot in 22 years. It measures 80,000 miles across or roughly the width of 10 Earths side by side. Definitely recommend watching it full-screen. (via Kottke)

An Aerial Laser Display Capable of Projecting 3D Objects in Mid-Air

A team of researchers in Japan lead by Akira Asano of Burton Inc. have developed a 3D aerial display capable of projecting text and imagery in mid-air. The Aerial Burton works by firing a 1kHz infrared pulse directly into a 3D scanner which in turn focuses and reflects the laser to a specific point in the air. Molecules at the end of the laser then ionize, releasing energy in the form of photons. While the full potential for such a display has yet to be seen, Asano suggests it could be used as a communication aid in the event of a disaster by communicating evacuation routes or broadcasting the location of emergency supplies. Personally, I would be satisfied with a 3D laser butterfly in my backyard. (via DigInfo)
