Now this is pretty awesome. Watch the patterns in the fog behind that building (viewed from the John Hancock Center, Chicago). You can make out a swirling, alternating vortex pattern. The fog is defining a Von Karman vortex pattern. 

I was thinking up new water-colour tattoo designs for my sister when this idea popped in my head C:
oh how I love the aesthetic of Max’s journal~

Flounders, stingrays, and other flat, bottom-dwelling fish often hide under sand for protection. These fish move by oscillating their fins or the edge of their bodies. They use a similar mechanism to bury themselves–quickly flapping to resuspend a cloud of particles, then hitting the ground so that the sand settles down to cover them. Researchers have been investigating this process by oscillating rigid and flexible plates and observing the resulting flow. When the flapping motion exceeds a critical velocity, the vortex that forms at the plate’s edge is strong enough to pick up sand particles. Understanding and controlling how and when these vortex motions kick up particles is useful beyond the ocean floor, too. Helicopters are often unable to land safely in sandy environments because of the particles their rotors lift up, and this work could help mitigate that problem.

The Smoke Angels.

Wingtip vortices shown in flare smoke left behind a C-17 Globemaster III.

How does an aircraft fly? Think of it like this, due to the design of the wing, larger number of air molecules are hitting the bottom portion of the aircraft than the top.

As a result, a upward force acts on the wing, hence the wing lifts!

This works fine till we get to the wing tips.

In the wingtip, the air from a higher pressure wants to move to the region of lower pressure. And as a result, this forms vortices ( fancy name for the swirling motion of air ) known as Wingtip Vortex. ( because its formed in the wing tips!!! )

And it is due to the ramification of this, that we obtain those gorgeous smoke angels. Pretty cool huh ?

Have a great day !

Intricate Calligraphic Steel Sculptures by  Zheng Lu

Composed of more than 20,000 Chinese characters, these intricate sculptures by Zheng Lu are soft and seamless in appearance despite their stainless steel make-up. The characters used are all chosen from Chinese texts and poems. For example, the sculpture that looks like a splash of water is cunningly crafted from the lines of the poem Wan Zhi Shui (Playing With Water) written by the Tang Dynasty poet Bai Juyi. This playfulness with details can be seen throughout Lu’s work. When discussing the use of one of the most original Chinese fonts in a specific piece, he said, “You would not figure that out from a distant view. Otherwise, it would not be fun.”

The contemporary Chinese sculptor has been interested in calligraphy for a long time. He grew up in a literary family with a strong traditional Chinese intellectual background and his father made him take up the practice of calligraphy when he was still very young. This skill is now apparent in much of his artwork and the inclusion of meaningful text brings a unique aesthetic and significance to Lu’s already elegant sculptures. Txt Via MMM
