spectrum: The Sun, photographed by Solar Dynamics Observatory, 28th August 2014.

10 frames; each frame is a composite of 3 images in different wavelengths. Here, I have used 3 wavelengths in the extreme UV range (17.1, 19.3, and 21.1 nm), for the blue, green, and red channels which usually represent visible light of about 475, 530, and 680 nm, respectively.

Sequence covers about 11 hours.

You Can Now Access All Of Richard Feynmans Physics Lectures For Free: 
 
The lectures of Nobel Prize winning physicist Richard Feynman were legendary. Footage of these lectures does exist, but they are most famously preserved in The Feynman Lectures. The three-volume set may be the most popular collection of physics books ever written, and now you can access it online, in its entirety, for free.
The complete online edition of The Feynman Lectures on Physics has been made available in HTML 5 through a collaboration between Caltech (where Feyman first delivered these talks, in the early 1960s) and The Feynman Lectures Website. The online edition is “high quality up-to-date copy of Feynman’s legendary lectures,” and, thanks to the implementation of scalable vector graphics, “has been designed for ease of reading on devices of any size or shape; text, figures and equations can all be zoomed without degradation.”
Volume I deals mainly with mechanics, radiation and heat; Volume II with electromagnetism and matter; and Volume III with quantum mechanics.
Go. Have fun.

Volumes I and III have been out for a while but now we finally have Volume II Electromagnetism and matter.I have these beautiful books in physical form. But easy internet access is great for on the go or at work for a quick reference or an amazing quote.

Broccoli Romanesco

Taxonomically classified as a cultivar of the same species as broccoli and cauliflower, Brassica oleracea, Broccoli Romensco is one of nature’s finest examples of the Fibonacci series. The flowering buds spiral outward, progressively terminating in a logarithmic extension of numerical harmony

Not only does this plant demonstrate universal beauty, B. oleracea is also a fully edible vegetable, high in vitamin C, K, and dietary fiber. The plant typically grows in environments high in salt and lime, predisposing this fractal veggie to perching off of limestone cliffs throughout Europe.

Researchers reveal new self-cleaning cashmere

Cashmere usually has to be cleaned by a dry-cleaner, and the process can be an expensive, sometimes-toxic, energy sap. But now researchers in Hong Kong have developed a new self-cleaning cashmere fabric that’s coated with an invisible layer of nanoparticles that makes stains disappear. And the best part? It’s only projected to be 1% more expensive than regular cashmere.
If you get dirt or coffee, red wine or bacteria on your self-cleaning cashmere, all you need to do is put it in some light for 24 hours. This will trigger a chemical reaction with the anatase titanium dioxide particles in the invisible coating to break down the stains.
According to Adele Peters at FastCompany, the team at the City University of Hong Kong’s School of Energy and Environment has been developing the material for over a decade, starting with cotton and wool, then moving on to cashmere, seeing as it’s one of the most difficult fabrics to clean.
"Cashmere is a sensitive protein and can be easily damaged and therefore it is notoriously expensive to clean,” one of the team, materials scientist Walid Daoud, told Peters. “It is a delicate operation, because of the risk of spoiling the cashmere in the process. How to apply nano-sized photocatalysts to cashmere and retain its delicate characteristics was a huge challenge.”
The last step in the process to get their self-cleaning cashmere to market is to complete some health testing to make sure any residue from the nano-particle coating doesn’t have any adverse affects on the wearer’s skin. So far, tests have shown the coating is durable and doesn’t harm the fibres of the fabric. "It should reach the market very soon," said Daoud. “We are currently working toward transfer of the technology to the industry.” 

"Ultimately, the technology could be used in all clothing,” says Peters, “eliminating, for laundry in the US alone, more than 179 million metric tons of CO2 emissions every year.
