I drew stuff like this as a child, and the teachers legit wanted me to go to therapy. https://t.co/bDSegzIJjc
Drawing humans with wings."The inhabitants of the town, believing him to be a lunatic, heretic, or a fraud, burned his "demonic" flapping-wing creation. MarĂn lost all hope and, feeling disgraced and deeply depressed, never attempted flight again."https://t.co/dheSUOWpD3
"literary and artistic production [suggests] that he saw animals as the true “image of the world.” While he included human beings in the group he called “animals,” it was not as preeminent entities, but as one of the world’s infinite, beautiful varieties."https://t.co/iT43vZ6tEU
“The men of experiment are like the ant; they only collect and use. But the bee gathers its materials from the flowers of the garden and of the field, but transforms and digests it by a power of its own.”― Leonardo da Vinci, Leonardo's Notebookshttps://t.co/at27CLBq2Q
"It is highly unlikely, however, that any of these machines were ever made or used in contemporary warfare. Indeed, as Leonardo himself wrote in his Notebooks, such new weapons were often as dangerous to their users as to the enemy."https://t.co/kw15AQYkXR
Kid's asked the damnedest things."sometime in the future we'll know enough [...] to identify the part of the bat genome that calls for wings [...] and put it into the human genome."https://t.co/EGm2M0AG8t https://t.co/rYjs5204Cw
"Badi al-Zaman ibn al-Razzaz al-Jazari (1136-1206) wrote his mechanical treatise, the [Book of Knowledge of Ingenious Mechanical Devices, also known as Automata] [...] Leonardo da Vinci is said to have been influenced by al-Jazari’s [devices]"https://t.co/Ri7rFUbyEW
"Simulator studies indicate that, for an aircraft with this wing area, 288 lbs of lift is obtained at 14 MPH. Since humans can easily run at well over this speed, a running takeoff down a slope is well within the design envelope."https://t.co/Y3xgTsAys7
Reading Galen's theories of bile on one hand, and theories of Leonardo Da Vinci on the other.All I can think is "I bet a structure that looks like holes exist, but they aren't for filtering"https://t.co/3WQ0RNrTai https://t.co/fZWjcUt3ao
Shame Leonardo didn't care to read the ancients.Apparently he avoided reading Avicenna, instead suspecting the pores theory.https://t.co/Ra7avvmwIy
Honestly, I'm just over here looking for crypts in the heart for bacteria to live, and wondering if the "pores" he saw were the result of heart worms.https://t.co/8j3erjy9GI https://t.co/mxzHUXcKfF
Still looking at what it would take to apprentice as a butcher.Apparently in america, there isn't a legalistic taboo against dissecting cadavers like in ancient times, I'd rather learn how to prepare meat at the same time as learning about anatomy.https://t.co/fT1IKGkXh5
"Gut strings were being used as medical sutures as early as the 3rd century AD as Galen, a prominent Greek physician from the Roman Empire, is known to have used them."https://t.co/VSdYzq07wLI wanted to know how to make sutures. By sheer coincidence, I was finding it.

"I roamed the countryside searching for answers to things I did not understand. [...] These questions and other strange phenomena engage my thought throughout my life."https://t.co/nA6eSTEEHfhttps://t.co/mVGhXgYMAb
Natgeo has a pretty good overview of al-Jazari https://t.co/lAyOirFqbF
"Citing the Byzantine siphon used for discharging Greek fire as an inspiration [...] when he invented a twin-cylinder reciprocating piston suction pump."https://t.co/8th3gaF3NFNice citations. Exploring mechanical engineering memes spread to trace how medical ones might have.
Annoying that wikipedia cites a book as being from 2013, when it was apparently originally published in 1984.https://t.co/4uVz3vSdIc
According to this historydotcom snippet [https://t.co/BlZGRlIsa3], it's possible the earliest known rocket may have been a torpedo designed by Hasan ar-Rammah https://t.co/4aRhaozV9Uhttps://t.co/4UYSix1v7yTracing closely to the history of gunpowder https://t.co/Svodla6yIh🎆

"Both Hero and Vitruvius draw on the much earlier work by Ctesibius (285–222 BCE), also known as Ktesibios or Tesibius [...] in Alexandria, Ptolemaic Egypt. He wrote the first treatises on the science of compressed air and its uses in pumps."https://t.co/lhBow0DboE
Museum dedicated to Badi al-Zaman ibn al-Razzaz al-Jazari opened in 2019. Looks cool!"We think that if we can revitalise his fabulous world, combining mechanics, science, art and philosophy, this would inspire a lot of people like us,"https://t.co/J71O46nH5Q

BRB turning water into wine.https://t.co/uIvFUug0Hl
"he created several different trick jars and jugs so that, through ingenious internal compartments, plumbing, siphons and air holes, a magician could alternate between the pouring of water or wine from the same vessel."https://t.co/2MHxyRU0B1
I wish I could figure out if these old Indian "Magic" Jars predated Pythagoras's greedy cup. This guy's videos are always fascinating, with reinterpretations of Indian Alchemy practice compared to the stories.https://t.co/Ko7oRNcEMd
Pythagorean Inertia."The tablet not only contains the world’s oldest trigonometric table; it is also the only completely accurate trigonometric table, because of the very different Babylonian approach to arithmetic and geometry."https://t.co/ZRqSCBoFwNhttps://t.co/mzJ2V42yO7
Lie-to-children, but we're all children needing to relearn history because we tell each other distorted ghost stories about what we see. Naively, we don't realize we're not seeing the truth. Myth begets myth ad infinitum.https://t.co/FCwAeY5vyy

"This tradition continued in Alexandria with inventors such as the Greek mathematician Hero of Alexandria (sometimes known as Heron), whose writings on hydraulics, pneumatics, and mechanics described siphons, a fire engine, a water organ, the aeolipile, and a programmable cart."
Gonna learn to draw dickbutt from memory.https://t.co/ItT4XpuGuG
Learning how to draw things from Renaissance Masters. "the human race is truly blessed to have made such a discovery. There are dick drawings like the ones you see on desks in school in Leonardo da Vinci’s notebooks. Please cherish this information." https://t.co/AhyKZTSXWi

"something that is uniquely ours. It is something we have created, that no one else can replicate (nefarious motives aside) in true likeness. [...] Let's not lose that piece of ourselves that once was our permission, our safety, our original brand."https://t.co/TKxzKEIYEq https://t.co/0B3knXETrB

"Leonardo's own sexuality appears to transcend gender, to slip into godlike fantasies of androgynous liaisons between worlds."https://t.co/ud01igDKWKOh, hey. That's the weird thing where people argued what gender angels were.https://t.co/7KydlEV7qN https://t.co/R80Am2WNoX
