"We live in a world where digital information is exploding. Some 90% of the world’s data was generated in the past two years. The obvious question is: how can we store it all? In Nature Communications today, we, along with Richard Evans from CSIRO, show how we developed a new technique to enable the data capacity of a single DVD to increase from 4.7 gigabytes up to one petabyte (1,000 terabytes). This is equivalent of 10.6 years of compressed high-definition video or 50,000 full high-definition movies."
Cat responds to rotational optical illusion. The illusion in question. But why does it work? Link to the actual paper.
From the mid 40s to the mid 50s Coronet Instructional Films were always ready to provide social guidance for teenagers on subjects as diverse as dating, popularity, preparing for being drafted, and shyness, as well as to children on following the law, the value of quietness in school, and appreciating our parents. They also provided education on topics such as the connection between attitudes and health, what kind of people live in America, how to keep a job, supervising women workers, the nature of capitalism, and the plantation System in Southern life. Inside is an annotated collection of all 86 of the complete Coronet films in the Prelinger Archives as well as a few more. Its not like you had work to do or anything right? [more inside]
"It is only fitting that the story of the brain should be a visual one, for the visuals had the ancients fooled for millenniums. The brain was so ugly that they assumed the mind must lie elsewhere. Now those same skeletal silhouettes glow plump and brightly colored, courtesy of a variety of inserted genes encoding fluorescent molecules. A glossy new art book, “Portraits of the Mind,” hopes to draw the general reader into neuroscience with the sheer beauty of its images."

Atmospheric Optics. Rainbows, in spray, of moonlight, in reflective paint, without sky, with spokes, twinned, reflected, in clouds, in the fog, more. Halos, horizon distortion, green flashes, pillars, near-contrails. Surface and volume shadows. Waves atop the atmosphere. Mysteries. Picture of the Day. Via. Previously. Still no unicorns.
"...we see on the ground a number of spots of light, scattered irregularly, some large, some small..."
The Nature of Light and Color in the Open Air "Moreover, this book is written for all those who love Nature; for the young people going out into the wide world and gathering together round the camp-fire; for the painter who admires but does not understand the light and colour of the landscape; for those living in the country; for all who delight in travelling; and also for town-dwellers, for whom, even in the noise and clamour of our dark streets, the manifestations of Nature remain." - Marcel Minnaert [more inside]
i began cataloging the colors, and put the color list on the web. over time, the paint catalog turned into a web site.
Athanasius Kircher was the 17th century's Jesuit version of the übergeek. His scholarly attentions were drawn to egyptology, astronomy, magnetism, languages, optics, music, geology, mathematics and many many other pursuits. The "dude of wonders" invented novel machines such as the mathematical organ and magnetic clock, established one of the first museums, published about 40 academic works (with beautiful accompanying illustrations) and was globally revered as one of his time's greatest intellectuals. He is also the main link in the Voynich manuscript mystery. [MI]
