Okay so this is one of the WEIRDEST FUCKING THINGS humanity has stumbled upon in science and it gives me a nerd boner that can be seen from Alpha Centauri.
As far as we can tell, this fucking thing generates reactionless thrust. Let that shit sink in: The EM Drive does not require fuel. Only electrical power.
Okay I know I said it already but AS FAR AS WE CAN TELL THIS IS A !!REACTIONLESS!! !!THRUST!! !!DEVICE!! you have no idea just how goddamn amazing that is
mark my words this fucking thing is going to REVOLUTIONIZEthe design of satellites and scientific probes
and just think of the potential it might have if its thrust increases proportionately to the power fed into it
THIS IS FUKCIN HUGE MY DUDES
Reblogging this just to restate how fucking huge this is.
Imagine you blow air into a balloon and tie it off. Then when you untie it, you let the balloon go and it flies all over the place. This is how propulsion works. This is what Newton’s Third Law is based on. That the air is coming out and pushing the balloon forward.
The EM drive is moving forward when the balloon is still tied off at the end.
I heard about this theorized not some time ago and thought it was amazing!
The fact that it’s been thoroughly peer-reviewed and still stands up is nothing short of absolutely astounding.
This device works, and no one is quite sure how or WHY it does. It defies our current understanding of why physics work the way the way they do. Which mean basically means that we need to re-evaluate and refine our laws of physics because we have discovered empirical evidence that we’ve got something wrong. And trying to fix our math to accurately describe the universe is going lead to new discoveries about the fundamental nature of reality. IT’S MIND BLOWING.
Not to mention this device itself, if we can elaborate and expand on it, will change how we do propulsion. This might the next stage of propulsion technology. To the people a few decades in the future, combustion engine propulsion technology will seem as silly, outdated, and quaint as steam propulsion or horse-drawn carriages seem to us.
THE FUTURE APPROACHES.
god I’m such a nerd
This is hugely important stuff.
A lot of reports on this thing talk about how it “breaks the laws of physics,” but this is an inaccurate oversimplification. The reality of it is much more profound. If this thing indeed works, and the results we’ve gotten thus far can’t be explained by some sort of experimental error, it will redefine our understanding of physics. In other words, the laws of physics aren’t being “broken,” we’ve just been wrong about physics the entire time.
so what you’re saying is maybe we get long distance space travel before we go extinct of our own stupidity
Yes.
So we built a machine and we don’t know how or why it works?
this single post is more useful to me then four years of art school
We did it in color study class on my college and it’s incredible the difference between using red/blue/yellow than cyan/magenta/yellow.
The purple was colored like shit, so as the greens. Than we tried the actuall primary colors and it FELT SO GOOD!
I JUST TESTED IT IN MY ART PROGRAM AND HOLY SHIT
IT WORKED REALLY WELL
On the left we have dissapoinment; on the right, love.
Then why do they teach us that RBY are primary colours in Pre-KG????
To mess with our heads….
Or because they think that cyan and magenta are too difficult for kids to learn? Lame either way
Reshare to save lives
Okay, no. No no no no no no no no NO.
Listen up you fucks because I’m not wasting thousands of dollars on an art degree to watch y’all fuck up basic color theory.
Red, yellow, and blue are the primary colors
If you’re using p i g m e n t.
Do you hear me? When you’re using traditional media, fucking actual goddamn paint, Bob Ross style, your primary colors are!
When you use paint, your primary colors are red yellow and blue and don’t forget it.
NOW THAT CHANGES COMPLETELY WHEN YOU GO FUCKING DIGITAL.
THE DIGITAL PRIMARY COLORS ARE RED BLUE AND GREEN IF AND ONLY IF YOUR WORK IS GOING TO STAY DIGITAL, ON THE SCREEN, AND NEVER LEAVE THE SCREEN, AND OF COURSE IF YOUR WORK IS GOING TO BE PRINTED. ON A PRINTER. WITH INK. THEN. AND O N L Y T H E N.
ARE YOUR PRIMARY COLORS.
CYAN.
MAGENTA.
AND YELLOW.
So say it with me folks!
Red yellow and blue, are the primary colors for traditional pigment that’s mostly used in paints and shit. You use red yellow and blue when you’re painting traditionally, Bob Ross style.
Red blue and green is light, which is what you’re painting with when you pick up your tablet and go digital.
CMYK is ink, and ink only. You could use cyan, magenta, and yellow as your primary colors in paint if you wanted to be a complete dick, but they’re not your primary colors unless your work is going to be printed using. i n k. The only time they could be considered the primary colors in a traditional medium is if you’re using ink.
Good day.
Also thatswhiskytoyou’s color mixing is bullshit because THIS:
Is my icon. I painted this using RED. GREEN. AND BLUE. AS MY PRIMARY COLORS and they turned out fine. Of course, I used the finger smudge tool first and then the color mixing tool and then the blur tool, but hey what do I know.
Clearly using the blur tool only doesn’t cut it.
“Oh but Leo!” You say. “You used cyan and magenta in that color wheel!”
Well bitch guess what.
this is the digital color wheel. I’d say I mimicked that pretty well, don’t you think?
Oh and one other thing, notice how Blue and Yellow are directly opposite each other on this color wheel? That’s because we’re dealing with light, and with light, yellow and blue are complimentary colors.
Which is why when you mix them, it looks like this:
Which is a pretty neutral gray tone: They cancel each other out on the rgb color wheel when you mix them together.
BUT WITH PIGMENT THE PLACEMENT IS DIFFERENT
If you’ll notice, yellow and violet are now opposite each other, meaning they’re complimentary colors and if you mix them, they’ll make a neutral gray.
But if you mix yellow and blue, same colors as before, YOU GET THIS:
Now keep in mind that the person in the video uses a darker blue, so they get a darker green, but the point is that it doesn’t make that neutral gray.
Now what happens when we mix yellow and violet paint?
Ah yes, you get a bunch of muted colors the more evenly you mix them.
What happens when you mix yellow light and purple light?
I see, I see.
OH AND ONE MORE THING.
They didn’t teach you about red blue green and cmyk in pre-k because when most of us were in pre-k digital art was still in its early stages and what fucking seven year old knows how to use a printer.
GUESS WHO’S NOT FUCKING DONE YET:
The reason the primary colors for light are so dramatically different from the primary colors for paint and ink is because your eye only receives combinations of red light, blue light, and green light. Our eyes do not have a sensor (cone cell) for yellow light. So when we paint with light, red green and blue are our primary colors. Because of our eyes.
Furthermore, paint primary colors are colors that cannot be created by mixing other colors together. For paint, they are red yellow and blue, because you cannot mix orange and green to get yellow. Mixing orange and purple paint does not make red. And mixing green and purple paint does not make blue.
Mixing blue and green paints will make cyan. Mixing red and blue paints will make magenta.
That’s why cyan and magenta aren’t primary paint colors.
However, you can’t mix yellow and blue ink and get cyan. You can’t mix red and blue ink to get magenta.
And that’s why cyan and magenta are the primary ink colors.
Brighter and stronger paints are created through tints and shades, through a thorough understanding of color theory and a few quality paint recipes. Not by bullshit posts on tumblr designed to mislead you.
Astronomers have detected a small asteroid that doesn’t seem to want to go away. Called a quasi-satellite, this new companion circles around the Earth as it orbits the sun—and it’s going to stay that way for the next few hundred years.
espybounce asked: Mitochondria may be the powerhouse of the cell, but I resent the fact that people don't care about its other functions! The mitochondrion isn't some goddess that dropped down from the sky to generate ATP! It's got a three dimensional personality and people keep type-casting it! Without mitochondria people would die of azotaemia, probably!
That One Unnamed Extinction Event That Happened When Blue-Green Algae Discovered Photosynthesis and Started Pumping the Environment Full of Oxygen, Which Was Toxic to All Other Life on Earth at That Point in Time
This extinction event did result in the extinction of more living organisms than any other, whether you rank by number of individuals, number of orders/genera/species, % of life, or amount of biomass, but they were all single-celled organisms, so they don’t even register on the metal scale.
The Current Slow Slide Due to Anthropogenic Environmental Modification
Habitat destruction isn’t very metal.
Late Devonian
Some super-weird shit died out, which is totally metal, but we have no idea why, which isn’t. It might not even have been an extinction event, just a decrease in the speciation rate. Jawed vertebrates totally unaffected.
End Ordovician
Second-largest extinction event after the End Permian (not counting those blue-green algae fuckers). Caused by tectonic plate shifting (kinda metal) and resulting glaciation (mildly metal).
Deep Impact
Pros: Giant asteroid hitting the earth.
Cons: Fictional.
End Triassic
Probably caused by massive volcanic eruptions, which is pretty metal, but mostly just wiped out some weird looking amphibians, which is only mildly metal.
End Permian
Greatest extinction event of all time (with the exception of that blue-green algae fiasco mentioned above), wiping out ~95% of all species: metal. Only known mass extinction of insects: metal. Probably caused by the biggest volcanic eruptions since life began (metal) which ignited massive coal beds (metal) and caused the release of methane from the ocean floor (metal) resulting in a runaway greenhouse effect that raised the average ocean temperature to 40C for several million years, essentially boiling the earth alive (super metal). Paved the way for dinosaurs to take over the earth: metal. Known as the ‘Great Dying’: totally metal.
However, most of the extinctions occurred in sessile marine organisms, which are way too boring to be metal, and for the first ~20 million years after the extinction event, land was dominated by Lystrosaurus, which is the most un-metal looking reptile you can think of.
End Cretaceous, aka the K-T Event
A GIANT FLAMING BALL OF ROCK HIT THE EARTH AND KILLED ALL THE (non-avian) DINOSAURS. ENOUGH SAID.
I agree with most of this post (I’d swap Permian/Cretaceous because the Permian was freakin’ metal, yo, but no biggie) but you don’t get more metal than the GREAT OXYGEN CATASTROPHE
The entire surface of the earth was POISONED by a GAS that SHOULD NOT EXIST according to the basic LAWS OF THERMODYNAMICS
It’s so metal that even billions of years later Earth has had to evolve entire ecosystems that METABOLIZE DEADLY POISON GAS. And survive by EATING EACH OTHER (which was probably not a thing pre-OXYGEN HOLOCAUST, you don’t need to bother eating each other if you aren’t trying to survive in a world full of IMPOSSIBLE DEADLY GAS.) Earth’s original inhabitants now have to eke out an existence in sealed-off channels in SOLID ROCK and similar places.
THAT IS AS METAL AS IT GETS.
(also there’s the nuclear fission reactions and stuff, that part’s fun. Did the dinosaurs have nuclear fission? NO.)
I wish i had a context for this. But I really dont.
I was all ready to “um, actually” this, but, um, actually there’s about 3-4 grams of iron in a person, which x400 is 1.2-1.6kg, which is a smallish but not unreasonable sword. So. Math checks out.
How would you extract the iron, though? The more practical solution would be to kill a mere hundred men, then mix 1 part blood with 3 parts standard molten iron, imo. Cheaper and faster, while still retaining the edge that only evil magic can give you.
Or, you could just make the sword of iron, and then use the blood to temper the blade.
1.2 to 1.6 kilograms is a perfectly reasonable large sword. Your average longsword was 1.1–1.8 kg and I don’t even remember if that’s including the weight of the hilt, guard, and pommel or just the blade. Your more classic “knight sword” was a mere 1.1 kilograms on average; the blood of 400 men is more than enough.
This is using the comparatively crappy metallurgy of medieval Europe and their meh iron swords. Move east to, say, contemporary Iran and make a scimitar using high carbon steel (~2%) for a .75 kilogram blade and you only need the blood of about 225 men.
So putting my thoughts in on this… because how could I not.
So you’ve exsanguinated your 400 guys to get the iron for your sword. Cool. But now you have 400 bodies lying around.
Why not put those to good use and cremate them. Use the carbon from those 400 bodies (you won’t need all of them) and now you can make a nice mid-high carbon steel sword.
Now you have a sword forged with the blood of your enemies AND strengthened with their bones.
