We desperately need to get stay at home moms into 3D modeling/3D printing. I say this every day and it never gets any less true.
We need to give these women the tools to do with 3D printers what they’ve accomplished with cutting machines. There are youtube videos out there with a woman who looks like she is personally your mom clearly using her own phone camera to record and saying “Ok we’re going to learn how to make a suuuper easy and fun cricut project! I whipped up the design for this while the kids were at school :)” and then shows off some 3D paper masterpiece that would take me 3 years in an architectural college to have designed.
We need this for the 3D printing world.
“Waah but then people might take the art less seriously and we’d see a bunch of people making a printing 3D knick knacks for etsy and it won’t be an exclusive club anymore :(((”
GOOD. I would LOVE for 3d printing to be relegated to the realm of “mom craft” the way laser/cnc cutting and engraving have. I would love for companies that know they can hike prices because it’s seen as a “techie” thing to have to make their product more accessible for lower income people to stay competitive with the market. I would love to see a bunch of little cute 3d crap on etsy or at craft fairs. I see no downside to this.
And if you see an art form as “less serious” or “less legitimate” because women are getting into it, then that’s on you.
this little freak keeps sneaking into my garden and rubbing himself all over my flowers??Hello?????
Real, male bees don’t go after flowers they stay home, that freak is a herself
googling ‘bee genders’ as I dictate this post
The more you google bee reproductive biology the more absurd it is that we’re applying the words male and female to them. Their actual genders are worker, drone and queen. The queen is capable of both asexual and sexual reproduction. Bees born of unfertilized eggs become drones that are capable of fertilizing eggs. Bees born of fertilized eggs become workers, but can also potentially become a queen depending on how they are fed during the larval stage.
Use whatever the fuck pronouns you want to describe bees because they’re all equally incorrect projections of human worldview onto an insect species. Bees don’t experience mammalian sexual dimorphism in a biological sense nor do they experience human gender dimorphism in a sociopolitical sense.
diversity win, the freak sneaking into your garden and rubbing themselves all over your flowers does not fit into a human biological or sociopolitical framework of sex and gender!
Why does cooked food offer more energy by bite? Does the heat weaken the bonds making it easier for us to break down and digest ourselves or something?
you know the molecular principles behind digestion, yes? probably?? they’re still teaching that in high school, right???
well, in case you need a refresher, I’ll address meat specifically: the basic principle is that meat is FULL of useful proteins structures that your body would really like to take and use for its own bits, but there’s a slight problem that needs to be dealt with first!
these proteins are FUCKING HUGE.
each protein is a sprawling 3-dimensional molecular structure containing hundreds to thousands of individual atoms, much much too big and also not quite the right shape for your body to repurpose!
and you need to start that blood vessel resurfacing project NOW, the funds were approved LAST THURSDAY for chrissake.
fuckin’ contractors. never on schedule.
so what your digestive system does is break the proteins down into their component chunks, via a process called denaturing! the denatured protein loses its structure and unspools itself into a long ribbon, which can be popped apart and taken to wherever those individual proteins need to go in your body.
HEY ED, GET A MOVE ON! THOSE TAURINES NEED TO BE AT THE LIVER ASAP!
and this denaturing process is fairly energy-heavy, so your body is BURNING energy and materials to PRODUCE energy and materials, and just barely comes ahead of breaking even!
at least, if we’re talking about raw meat.
see, your digestive system denatures proteins through an expensive chemical system, but it turns out there’s a cheap, easy, and (almost) FREE alternative that will do the same thing, no enzymes needed!
heat.
heat denatures proteins by its very nature, and we can actually see the process happen if we pay attention!
transparent egg whites turn milky and opaque as their regimentally organized protein structures unspool and tangle each other into uselessness, and red pigment proteins in muscle fibers turn grey as their molecular structure changes so drastically that it reflects an entirely different spectrum of light!
if you’re a human being, you refer to this process as “cooking”.
so when humans first started chucking chunks of mammoth into the fire way back when, they found they could use the fire to pre-digest the meat into useable protein chunks that take WAY less energy for your body to do something useful with, resulting in a net energy gain in the digestive process even though no extra energy was actually added to the meat!
in conclusion:
FIRE GOOD.
thanks for listening to my TED talk.
I’m not an expert here, but there’s a similar thing going on with plants. Except instead of protein, it’s polysaccharides like cellulose. We can digest a few of them as delicious, delicious starches, but others can’t be absorbed by the intestine, and wind up as dietary fiber.
A lot of herbivores have incredibly long digestive tracts to ferment those polysaccharides into something digestible (this is why cows have so many stomachs). Humans can do a little of that–that’s why beans make you fart. It’s the gut bacteria breaking down polysaccharides and releasing gas in the process. Pills like Beano contain an enzyme to break down the polysaccharides before the bacteria get to it.
Anyway, all that is to say that, given we can’t break down cellulose like a cow can, and since plant cells are wrapped up in a shell of cellulose, cooking breaks down the cellulose that encases plant cells enough that we can get access to whatever is inside (like vitamins, or more delicious, delicious starches).
not to derail this but it’s posts like these with such easy to digest (sorry) and passionate explanations to scientific questions that pushed me into the science education field. we might rag on some of the science side of tumblr posts from 2014 but actually that shit fucking slaps and comes in handy when teaching “complex” topics to people. the way this post is written is how i teach.
