Better Than A Van Gogh: NASA Visualizes All The World’s Ocean Currents. Our oceans are every bit as turbulent as “Starry Night.”
We imagine the ocean as having high tides and low tides, water that comes in and out in waves. Beyond that, how does water actually move around the world? What’s that flow look like?
What you’re looking at is the surface current flow (not anything deeper) of oceans around the world, recorded from 2006 to 2007. The white lines are the currents, and the darker blue colors of the water represent bathymetry (the fancy word for misnomer “ocean topography”).
NASA Scientific Visualization Studio assembled this remarkable animation of the surface currents of our oceans. It’s called Perpetual Ocean, and the full work is 20 minutes of HD video, assembled from a huge amount of satellite, on location, and computational data generated by ECCO2 (Estimating the Circulation and Climate of the Ocean, Phase 2). ECCO2 itself exists to better understand our oceans and their role in the changing global climate.

Adam Savage dipping his fingers into a pot of molten lead. Immediately prior to submerging his fingers in the lead, he wet them with water, which will form a thin protective layer of water vapor on contact with the lead, which was heated to 850 degrees Fahrenheit. This is known as the Leidenfrost effect.
THAT IS TERRIFYING
even though i know youd be fine i COULD NOT do this
I’d be like “NOPE.”
This is one of the few episodes I’ve actually seen.
THAT CAT GIF
MY HAND HURTS JUST THINKING ABOUT THIS
Laughing so fucking hard at that cat gif. Accurate.
The Greek atomists were the first to ponder the fundamental constitution of matter. They considered, in an amazingly prescient insight, that if you could cut matter into smaller and smaller pieces you’d end up with its smallest bits, which they called atoms.
The word itself means that which cannot be cut. They further considered that atoms were eternal and indestructible, thus constituting the essence of Being. However, as they combined with each other in myriad ways, they made up all the stuff that we see in the world, from rocks to water drops to frogs and people. This way, Being turns into Becoming, capturing the essence of nature, of things that are and things that change. They went further, and in an attempt to create a unified theory of nature, proposed that thoughts and feelings were also made of atoms. Unified theories are as old as philosophy.
Although the modern concept of atoms is quite different from that of the pre-Socratic Greeks, the notion that matter is made up of small, indivisible bits remains alive and well, constituting the basis of elementary particle physics, the branch of physics that tries to find the fundamental constituents of matter. - Marcelo Gleiser

Thankfully, not needed.
IN THE EVENT OF MOON DISASTER:
Fate has ordained that the men who went to the moon to explore in peace will stay on the moon to rest in peace.
These brave men, Neil Armstrong and Edwin Aldrin, know that there is no hope for their recovery. But they also know that there is hope for mankind in their sacrifice.
These two men are laying down their lives in mankind’s most noble goal: the search for truth and understanding.
They will be mourned by their families and friends; they will be mourned by their nation; they will be mourned by the people of the world; they will be mourned by a Mother Earth that dared send two of her sons into the unknown.
In their exploration, they stirred the people of the world to feel as one; in their sacrifice, they bind more tightly the brotherhood of man.
In ancient days, men looked at stars and saw their heroes in the constellations. In modern times, we do much the same, but our heroes are epic men of flesh and blood.
Others will follow and surely find their way home. Man’s search will not be denied. But these men were the first, and they will remain the foremost in our hearts.
For every human being who looks up at the moon in the nights to come will know that there is some corner of another world that is forever mankind.
PRIOR TO THE PRESIDENT’S STATEMENT: The president should telephone each of the widows-to-be.
AFTER THE PRESIDENT’S STATEMENT, at the point when NASA ends communications with the men: A clergyman should adopt the same procedure as a burial at sea, commending their souls to “the deepest of the deep,” concluding with the Lord’s Prayer.

An account of a rare sighting: that of a leucistic, or a nearly all-white penguin, by a National Geographic expedition team in Antarctica:
Despite colorful variation in facial patterns, all penguins are decked in the standard black and white pattern. This is no accident. Counter-shading camouflage in so necessary to diving birds that all are fundamentally alike. But to our astonishment we found an exception. At the water’s edge stood a leucistic Chinstrap. This bird was whitish, but not quite an albino. Instead, it had pigmented eyes and a washed-out version of a Chinstrap’s normal pattern. Many wondered about this unusual bird’s chances of success. While odd coloration may make fishing a bit more difficult, leucistic birds are regularly found breeding normally.
Despite its appearance, there is order in the chaos of turbulence. These snapshots from a turbulent channel flow simulation outline these coherent structures in black. The top photo shows a top view looking down on the channel and the bottom image shows a side view of the channel. It is thought that studying these coherent structures may help shed light on turbulence and its formation, which remains one of the great open questions of classical physics. (Photo credit: M. Green)
Astronomers report that they have taken the measure of the biggest, baddest black holes yet found in the universe, abyssal yawns 10 times the size of our solar system into which billions of Suns have vanished like a guilty thought.
One of these monsters, which weighs as much as 21 billion Suns, is in an egg-shaped swirl of stars known as NGC 4889, the brightest galaxy in a sprawling cloud of thousands of galaxies about 336 million light-years away in the Coma constellation.
The other black hole, a graveyard for the equivalent of 9.7 billion Suns, more or less, lurks in the center of NGC 3842, a galaxy that anchors another cluster known as Abell 1367, 331 million light-years away in Leo.
“These are the most massive reliably-measured black holes ever,” said Nicholas J. McConnell, a graduate student at the University of California, Berkeley, in an e-mail, referring to the new observations.
These results are more than just cool and record-setting. Observations with the Hubble Space Telescope over the years have shown that such monster black holes seem to inhabit the centers of all galaxies — the bigger the galaxy, the bigger the black hole. Researchers said that the new work could shed light on the role these black holes play in the formation and evolution of galaxies."
Prepare the red matter!!! OH WAIT RED MATTER WON’T MATTER!
Hint: It doesn’t.
Great post, but I wish they had gone into some real reasons or thoughts behind why there is such a monoculture in CS and the Web scene. I feel the social perception of computer proficiency coupled with the façade of required math skills lead to a cultural divide, especially among younger kids. This is not only a gender issue, but an issue with the culture as a whole. It has become slightly more acceptable, but for the most part, it is okay to love movies or games or tv or sports or art or shoes, but if what you love is computers in the abstract. If your passion is building things for the computer and spending your time pouring over code, you are a geek, a weirdo, you are out of touch. This is highly amplified in the adolescent years, and thats when people get on the CS track or not.
