what is the flow rate of gojo’s sperm? 🤔
😈 😈 😈 ALRIGHT LET’S FIND OUT
shoutout to m00tie @quinnyundertow since u said there's nothing that turns you on more than hearing how mobile a man's flagella are. this one's for you bb.
Tumblr media Tumblr media
alright, first off, because his cum is confirmed to be both incompressible fluid as well as move with laminar flow, these attributes satisfy the conditions of pouiseulle’s law:
Tumblr media
i had to do a little bit of research to determine if it was laminar or turbulent flow, and apparently sperm travels with both stokes & laminar flow, which is pretty interesting, and also moves in a sinusoidal propagating wave, likely due to the movements/shape of the flagella
Tumblr media Tumblr media
note: microscopic sperm travel & ejaculate fluid travel are two very different things, but i can’t solve for anything microscopic here so we’re just gonna go for the ejaculate fluid only
anyways, to use pouiseulle’s law, let’s first determine our variables, and make sure we get the units right as well! always draw a diagram w all the variables:
Tumblr media
now, let’s identify the variables:
1. radius (r) of tube -> this refers to the pipe/tube, therefore in this case, the vaginal canal. now since gojo has decided to creampie, we can assume that the radius of the vaginal canal will be equivalent to the radius of his girth as he is stretching you out. gege told me the diameter of his big fat schlong is approximately 3 inch girth, therefore the radius = 3/2 = 1.5 inches
2. ΔP refers to change in pressure gradient, in this case i’ve decided to have P1 as pressure at vaginal canal opening, and P2 as pressure at the end where the cervix is. therefore, ΔP = (P1 - P2) for the equation. i know you’ve got that gorilla grip coochie, esp when the world’s strongest sorcerer is fuckin you SENSELESS, but all things considered this is a very difficult parameter to measure, therefore i found this article to help out with this:
Tumblr media
we’re going to assume “contraction pressure” (at the vaginal canal opening) is P1, due to gojo’s intrusion. and we’re going to assume “pressure at rest” is P2 at the end near the cervix (he’s pulled out a lil bit ok this makes things easier for me)
kPa are the units that we want for ΔP in this case, therefore it’s a simple calculation:
ΔP = P1 - P2 = 41.8 kPa - 26.8 kPa = 15 kPa
3. the last variable we need to account for here is L, which is the length of the PIPE HE’S LAYIN INSIDE OF YOU (jk it’s just length of ur coochie). now, i imagine this man is a generous lover, and he’s alr made you cum a few before he stuck it inside, so with arousal, the vaginal canal length has likely increased to about 5 inches (moreso 4.75in based on avg values in research but he stretched you in even more during the sexing!!) therefore L = 5 in
4. the other two values are just constants:
π = pi 3.1415 (imma just use pi function in calc)
η = this is viscosity of a fluid. based on this research article, the viscosity of human semen is approximately 9.35 cps. we want these units in kPa•s (remember that your units need to match the units of the other variables), so we need to use density of sperm (1.043 g/ml) to convert the factor (i just used chatgpt lol) but the conversion factor is pretty similar therefore we will just plug in something close to 9.35 kPa•s (true value is a little smaller)
ALRIGHT WONDERFUL! WE HAVE DETERMINED ALL OF OUR VARIABLES :) NOW WE JUST NEED TO PLUG IT INTO OUR EQUATION/DIAGRAM:
*note: mind the units! (shown in blue) there are lots of variations on how flow rate can be shown w the units, so u wanna be careful that they match
Tumblr media
YAAAAY!! so the flow rate (Q) of gojo’s cum is approximately 0.63787 in^3/sec ☺️💕
use a quick converter online, and we can make it into liters per minute -> 0.02214 l/min. convert this to milliliters -> 22.14 mls
which means that, in one of gojo’s average cumshots, he cums 22.14 mls of ejaculate !!! :0 sheesh that’s a lot!!
but how does this value compare to other men? research varies, but on average, men ejaculate between 1-10mls per orgasm, therefore the world’s strongest sorcerer cums more than TWICE the worldwide average!!
and one final calculation shows us that when he finishes, it’s at about 0.369 mls per second :) that's fuckin fast!!!
Tumblr media
thank you for cumming to my ted talk!! byee
alr ellie out ✌🏼😖 (i have sm brainrot)

How stable are planetary systems? Will Earth and its seven siblings always continue in their steady celestial paths, or might we one day be randomly ejected from our cosmic home? Physicists understand the rules that govern the orbits of two celestial bodies, but as soon as a third is added (let alone a fourth, fifth, or hundredth) the dynamics become far more complex. Unpredictable instabilities arise, in which an object may be randomly ejected into space or fall into its host star. The so-called "three-body problem" has troubled scientists for centuries (and more recently forms the premise of a bestselling series of science fiction novels and a new Netflix adaptation). One obstacle to understanding it has been that we know relatively little about how common it is for such catastrophic instabilities to arise. In a new study published in Nature, we and our colleagues have shed some light on this question. In a survey of nearby stars, we found as many as one in dozen pairs of stars may have devoured a planet, likely because the planet developed a "wobble" in its orbit and fell into the star.

It’s been such a long week, y’all. There’s so much to do everyday, and there’s barely a chance to slow down and collect my thoughts! The picture on the right is from my physics lab. That thing is just as complicated as it looks, lol. At first, my equipment was faulty so I kept getting weird results and it was so confusing. But now, I’m headed on the right track!

look, I know I've talked about this essay (?) before but like,
If you ever needed a good demonstration of the quote "Any sufficiently advanced technology is indistinguishable from magic", have I got an exercise for you.
Somebody made a small article explaining the basics of atomic theory but it's written in Anglish. Anglish is basically a made-up version of English where they remove any elements (words, prefixes, etc) that were originally borrowed from romance languages like french and latin, as well as greek and other foreign loanwords, keeping only those of germanic origin.
What happens is an english which is for the most part intelligible, but since a lot everyday english, and especially the scientific vocabulary, has has heavy latin and greek influence, they have to make up new words from the existing germanic-english vocabulary. For me it kind of reads super viking-ey.
Anyway when you read this article on atomic theory, in Anglish called Uncleftish Beholding, you get this text which kind of reads like a fantasy novel. Like in my mind it feels like it recontextualizes advanced scientific concepts to explain it to a viking audience from ancient times.
Even though you're familiar with the scientific ideas, because it bypasses the normal language we use for these concepts, you get a chance to examine these ideas as if you were a visitor from another civilization - and guess what, it does feel like it's about magic. It has a mythical quality to it, like it feels like a book about magic written during viking times. For me this has the same vibe as reading deep magic lore from a Robert Jordan book.

Surviving Rainfall

Water striders spend their lives at the air-water boundary, skittering along this interfacial world. But what happens when falling rain destroys their flat existence? That's the question that motivated today's research study, which looks water striders subjected to artificial rain. (Image credit: top - H. Wang, animations - D. Watson et al.; research credit: D.

Things my extremely Italian physics professor has said:
“If you are walking in the woods nearby Chernobyl, you will probably be fine. But if you pick something up off the ground and eat it, you will die of radiation poisoning. Of course you may die if you eat things from the ground in other places, also, but likely not of radiation.”
“Unfortunately there is nothing I can teach you that will prevent you dying if there is on your house a hydrogen bomb. That is a politician problem. If any of you are president later, please do not hydrogen bomb my house.”
“Radioactivity could perhaps be used by terrorists, but it has not yet. Likely this is because terrorists do not study much physics.”
“Why is it that physics graduate students cannot make a nuclear bomb? It is not that they do not want to. They simply have not the money to buy the materials. Or anything else.”
