Living on the shore of Lake Ontario, just east of Toronto, photographer Matt Molloy has daily encounters with brilliant sunsets and cloudscapes that he’s been taking photographs of for over three years. One day he began experimenting with time-lapse sequences by taking hundreds of images as the sun set and the clouds moved through the sky. Molloy then digitally stacked the numerous photos to reveal shifts in color and shape reminiscent of painterly brush strokes that smeared the sky. You can learn more about his “timestack” technique over at Digital Photo Magazine and prints are available here.
my love for these is absolutely infinite
A 3D Printing system that can create forms without the hindrance of gravity - video embedded below:
A brand new method of additive manufacturing. This patent-pending method allows for creating 3D objects on any given working surface independently of its inclination and smoothness, and without a need of additional support structures. Conventional methods of additive manufacturing have been affected both by gravity and printing environment: creation of 3D objects on irregular, or non-horizontal surfaces has so far been treated as impossible . By using innovative extrusion technology we are now able to neutralize the effect of gravity during the course of the printing process. This method gives us a flexibility to create truly natural objects by making 3D curves instead of 2D layers. Unlike 2D layers that are ignorant to the structure of the object, the 3D curves can follow exact stress lines of a custom shape. Finally, our new out of the box printing method can help manufacture structures of almost any size and shape.

I DON’T UNDERSTAND
Various cloud formations might be one of the most beautiful and romantic sights in nature, but these masses of liquid droplets is also a complex and scientifically interesting phenomena.
SCIENTISTS SOLVE MILLENNIA-OLD MYSTERY ABOUT THE ARGONAUT OCTOPUS
The argonauts are a group of octopuses unlike any other. The females secrete a thin, white, brittle shell called the paper nautilus. Nestled with their arms tucked inside this beautiful, translucent home, they drift through the open ocean while other octopus species crawl along the sea floor. The shell is often described as an egg-case, but octopus specialists Julian Finn and Mark Norman have discovered that it has another function – it’s an organic ballast tank.
An argonaut uses its shell to trap air from the surface and dives to a depth where the encased gas perfectly counteracts its own weight, allowing it to bob effortlessly without rising or sinking. Finn and Norman filmed and photographed live animals in the act of trapping their air bubbles, solving a mystery that has been debated for millennia.
Since 1923 and the work of Adolf Naef, the shell has been viewed as a container for the argonaut’s eggs. After mating with a male (who is around 8 times smaller and 600 times lighter), the female secretes the papery shell using the tips of two large tentacles. She lays her eggs within the structure before snuggling inside herself. Besides her eggs, her only housemate is one of the male’s arms – the hectocotylus. The arm doubled as a penis, snapped off during sex and stays inside the female’s body….

I’m all for scientific discovery, and I get that they needed solid proof and documentation, but here’s my take on it. She’s floating around in something you CALL a nautilus, the name of a type of marine animals that uses its shell (which is shaped a lot like the pouch the argonaut octopus makes) as basically an adjustable buoy system, how could you NOT realize that she’s using it as a buoy system too?! According to the article that’s linked people did think that might be the case, but it just seems really obvious to me. I dunno. Whatever.
Cool stuff! Nifty cephalopods! :D Yay nature and science! :D
Opalized wood. Petrified wood is basically fossilized wood that has had it’s organic matter replaced by a mineral such as agate, bit by bit, as it decomposes. The wood structure is maintained, but the wood fibers are slowly changed into stone. Sometimes a jasper, quartz, pyrite or even opal(shown above) can be found fossilized in wood.
Today in physics our teacher put a metal ring over a bunson burner to see if it would expand or contract and while it was silent and we were waiting for it to heat up someone just whispered
one ring to rule them all
That totally would have been me. I’ve done similar things before. Mwuahahaha!
If I had been there, and someone else had said that, I probably would have literally shouted YES! or something, and then I’d want to at least high five the person who said it, but preferably I would glomp them. :)
The orbits of the moons and planets form a fractal 4-dimensional helix in spacetime.
A wave and a circle are both two-dimensional projections of a helix.
Romney doesn’t understand why you can’t roll down windows on a plane. He says ”It’s a real problem.”
OH FOR FUCK SAKES MAN.
“—you can’t find any oxygen from outside the aircraft to get in the aircraft, because the windows don’t open. I don’t know why they don’t do that. It’s a real problem. So it’s very dangerous.”
This makes me sad, because even if you take out the issue that it would actually suck the oxygen out of the airplane, thus hurting the passengers (though, admittedly, helping to put out the fire),
IT IS NOT GOOD TO ADD OXYGEN TO A FIRE (not that you could, since there is very little oxygen at high altitudes). ADDING OXYGEN WILL MAKE THE FIRE WORSE.
I mean, the only way I can figure the logic behind his remarks, is that he’s thinking about the fact that’s very difficult and extremely dangerous to breathe in smoke. Yes, opening the windows would help get rid of the smoke, but it would lead to lots of other problems.
Now, I know nothing about planes or how they function (except for Bernoulli’s principle; that one I know), but perhaps there is value in having a small port hole of some kind to allow smoke to be sucked out and then quickly closed before too much air is lost. But for all I know, just that one small port hole could cause the whole plane to crash, I don’t know. But assuming that opening it would not cause the plane to crash, and assuming that it could be easily and quickly closed, it’s not such a bad idea.
Wow. What the hell? Did I just defend Mitt Romney? That was completely unintentional. I truly think he’s a delusional bigot and needs to forever remove himself from politics and all forms of power and/or authority. But this particular idea has some merit. SOME.
Minute physics: There is no pink
Nope, none. Pink does not actually exist. I’m a fan of pink, as you may have noticed from the design of this website, but it doesn’t actually exist. It’s your brain inventing the color because it doesn’t know what else to put there. So… tada.
omg. okay this is weird. life changed forever.
Actually that’s kind of awesome. Pink is an imaginary color.
It’s like the unicorn of color!
Who says the internet isn’t educational? ^^
When the worlds of art and science collide, inspiration sometimes strikes in the sparks. Artist Roshan Houshmand creates a new perspective on the world of particle physics through her paintings, transforming physics into art. The paintings are based on the tracks of subatomic particles through bubble chambers, which are one of many kinds of detectors in particle accelerators designed to track particle movements. Bubble chambers are filled with superheated liquid, and the charged particles boil the liquid as they race through and leave a trail of bubbles behind. These compellingly beautiful patterns inspired Houshmand to create her series of ‘Event Paintings’. “I loved the sophisticated, simple playfulness of lines depicting charges, energies, speeds, mass and so much more,” Houshmand says. “There is something so pure and primal and universal about the movement of the trails and swirls and dancing lines against the black, which exist for less than a breath of time before they disappear.”
