The future is coming! Some are calling it the 3rd or “3D Industrial Revolution”. But how does 3D Printing work, and what can you expect?
…so basically what everyone failed to explain to me is that 3D printers are replicators.
I don’t know why I didn’t get this myself, but suddenly I’m really excited
Just a reminder:the natural diet of these birds is BONES. Not just bone marrow; actual bone shards. They pick up huge freaking bones from carcasses and drop them onto rocks until they get spiky pieces and then they swallow them. Their stomach acid dissolves bone.
look me in the eye and tell me that’s not a fucking dragon
And they aren’t naturally red like that. That’s self-applied makeup. They find the reddest earth they can to work into their feathers as a status symbol.
And they don’t scavenge other parts of carcases, just the bones. 85-90% of their diet is exclusively bone. Hence why it’s only a myth that these birds would just pick up whole lambs and carry them off. It’s not true, but in German they’re still called Lämmergeier as a result.
Inflating a set of cat lungs
Lungs are by most accounts mundane. Everybody has them, few give it much thought. But sequestered within darkness of the chest cavity, enveloping the fluttering heart, there’s a incredible wonder to this oddly inflatable organ.
Dissection is a destructive process. Rudely excised from membranous mooring and nourishing vessels, the deflated lungs appear little more than bloodied meat; amorphous and exposed…….until a breath of air unfurls its secret glory.
Here, a set of cat lungs is inflated with a straw. Comprised of hundreds of millions of microscopic air sacks called aveoli, Mammalian lungs harbor air capacity that is difficult to believe unless seen. The color of the entire organ lightens into a soft pink, as each microscopic sac fills with air.
A debt of gratitude is owed to cyborgraptor for her assistance in creating these gifs, as well as the students that help me film this demo.
(WWF via National Geographic) Thousands of New Species Found in New Guinea
Blue-Eyed Spotted Cuscus
The blue-eyed spotted cuscus (Spilocuscus wilsoni) is a small possum that was found in 2004 on Indonesian New Guinea.
Overall, the island hosts the highest diversity of tree-dwelling marsupials in the world, with an incredible 38 species, WWF says.

THE THIRD ONE
"Sweet little kittens are transformed in a fire. Crawling from the ashes come forth grinning metallic devils with sharp claws and fire blazing in their eyes."
The Ocean Array Plan. Devised by 19yo Boyan Slat, this passive system, if installed, could clean up both The Great Pacific Garbage Patch & The North Atlantic Garbage Patch. Sort of like an anchored Roomba for the ocean…
"Although extensive feasibility studies are currently being conducted, it has been estimated that through the selling of plastic retrieved over the five years, the money would surpass the initial cost to execute the project. In other words, it may even be potentially profitable. Because the main deterrent to implement large scale cleanup projects is due to the financial cost, this solution could perhaps pave ways for future innovations of global cleanup to also be invented.”
This is huge.
I approve of this. Hopefully a system can be set up where all profits from this project go back into cleanup efforts
I’m nineteen and I’m wasting my life behind a computer screen on tumblr what the heck
The Blue Dragon (Glaucus atlanticus), one of the world’s rarest and most beautiful mollusks
that’s an alien, that’s an alien dragon baby. that’s the coolest thing I’ve ever seen
YES FINALLY BACK ON MY DASH I LOVE THIS LIL FUCKER. LOOK AT IT
ohy my fucking god i finally know how my patronus looks like
So of course I read up on it. It’s even more beautiful when it’s in the water, not collapsed like it is on the original pic. It also freakin’ eats Portuguese Man o’Wars. They are also hermaphroditic because, damn, they so pretty, no way are they gonna hit anything but theyselves.
My spirit animal.
nothing will stop me from believing this is a baby lugia
Hydrothermal Worm under 525x magnification.
Hydrothermal worms are deep sea creatures, almost as small as bacterium, and are largely found near hydrothermal vents in the ocean. The image was taken using an FEI Quanta Scanning Electron Microscope, the real width of the field in the image is 568μm, or 568/1000 of a millimeter.
This legitimately upsets me.
… Y’see, now, y’see, I’m looking at this, thinking, squares fit together better than circles, so, say, if you wanted a box of donuts, a full box, you could probably fit more square donuts in than circle donuts if the circumference of the circle touched the each of the corners of the square donut.
So you might end up with more donuts.
But then I also think… Does the square or round donut have a greater donut volume? Is the number of donuts better than the entire donut mass as a whole?
A round donut with radius R1 occupies the same space as a square donut with side 2R1. If the center circle of a round donut has a radius R2 and the hole of a square donut has a side 2R2, then the area of a round donut is πR12 - πr22. The area of a square donut would be then 4R12 - 4R22. This doesn’t say much, but in general and throwing numbers, a full box of square donuts has more donut per donut than a full box of round donuts.
The interesting thing is knowing exactly how much more donut per donut we have. Assuming first a small center hole (R2 = R1/4) and replacing in the proper expressions, we have a 27,6% more donut in the square one (Round: 15πR12/16 ≃ 2,94R12, square: 15R12/4 = 3,75R12). Now, assuming a large center hole (R2 = 3R1/4) we have a 27,7% more donut in the square one (Round: 7πR12/16 ≃ 1,37R12, square: 7R12/4 = 1,75R12). This tells us that, approximately, we’ll have a 27% bigger donut if it’s square than if it’s round.
tl;dr: Square donuts have a 27% more donut per donut in the same space as a round one.
god i love this site
what a bunch of nerds
Doughnuts are made toroidal to improve surface area to volume ratios and to conserve consistent texture during frying. It’s difficult to properly cook anything larger than a Tim Bit doughnut hole otherwise. Think of a doughnut as a ring of doughnut holes in terms of thickness. Squared doughnuts are novel and all, but the corners are slightly thicker and consequently less cooked in the centre than the sides. I’m Canuckistani, I know these things.
