“The Igloo Village in Kakslauttanen, Finland is like the Rolls-Royce of ice hotels. Each igloo is equipped with glass that allows you to gaze at the northern lights and millions of stars, all while relaxing comfortably in your warm room.
The glass igloo is a a marvel of modern technology, which is based on a groundbreaking idea and years of research and development. Built from special thermal glass, the view stays clear even when the temperature outside drops to under -30°C. Every igloo is equipped with a toilet and luxury beds and, every evening, a hot sauna and a refreshing ice hole await you.”(via Glass Igloos with Magnificent Northern Lights Views - My Modern Metropolis)

Oobleck is a commonly utilized fluid in demonstrations of non-Newtonian behavior. Rather than being linearly viscous with respect to shear, oobleck is shear thickening, meaning that it becomes more viscous the more that it is sheared. This is what causes crazy formations when it’s vibrated, makes it useful as liquid armor, and enables people to run across pools full of it. Yet it flows readily when undisturbed. #
This video on superfluids is one of my favorite physics related videos on the web… It’s just a really cool demonstration… And it’s not too long, so enjoy!
P.S.: I know it’s been posted before, but it came around the tumblosphere again, so I reblogged it.
Flowing soap films provide an educational and beautiful method for visualizing the wakes of objects in two-dimensional flows. High-speed photography highlights the interference patterns on the soap film, providing detail without the necessity for the particulate tracking of other flow visualization methods. Highlights here include wakes behind bluff bodies, interacting cylinders, and flapping flags. (pdf) #
“A wide field meteor camera at NASA’s Marshall Space Flight Center recorded this spectacular meteor breaking up in Earth’s atmosphere on Sept. 30, 2011, 8:37 p.m. EDT. Also visible is a star-like object moving slowly toward the upper middle of the field of view — the upper stage of the Zenit booster that launched the Russian Cosmos 2219 intelligence satellite back in 1992. Orbiting 500 miles above Earth, this empty rocket body can get bright enough to be seen with the unaided eye.”

This year’s Nobel Prize in chemistry was awarded to Dan Shechtman for his discovery of quasicrystals. Quasicrystals, unlike traditional crystals, are aperiodic on the atomic level. Basically, their patterns don’t repeat. When Shechtman first saw this in an experiment in 1982, this was scientific heresy. Crystals were periodic, period. Shechtman must have made a mistake. But he hadn’t, and rather than sitting around sulking about his doubtful colleagues, he worked hard to eliminate possible errors and build further evidence for the existence of quasicrystals. The tide of evidence turned in his favor, and the field of crystallography was changed forever.
In hindsight, quasicrystals are the sort of thing that seem to be too beautiful not to exist. (Which is not to say that, just because a theoretical structure is beautiful, it always turns out to exist—it doesn’t.) Although it took until 1982 to find evidence of atomic patterns that were not periodic, aperiodic tilings show up on the walls of mosques as early as the 12th century.
