" I slowly start falling to dust. " - - - hmhmhm going through the pages of your math book isn't only scary, it is also a nightmare. So many examples, so many questions. Each of them unsolved, waiting to be calculated. arghh get out of my head! get out of my life! begone already! the never-ending math drama is starting all over again and the only way out of it is with distraction like art and music. ah yes. - and then? ...?

who's hand is in this picture?
Tumblr media
A Mathematically Rigorous Proof That I Spent Too Long Writing
welcome to university math: dnp hand edition
(no, don't leave, you'll be fine i promise)
to begin, we need a statement to prove. we have two options:
- the hand is dan's hand
- the hand is phil's hand
now, for most proofs in university math, you are told a true statement, and you must show why it is true using logic rules, definitions, and theorems. but, we do not know which of these statements are true, so we have to find out.
to prove that a statement is true, we must show that it is always true for the situation presented. to show a statement is false, we must present a single instance where the statement is false (also known as a counter example).
a quick not scary math example:
definition: a prime number is only divisible by 1 and itself.
statement: all prime numbers are odd
(this is false, because 2 is a prime number and it is even. you don't even need to check if there's any others, all you need is one single case where it isn't true to disprove it)
so now that we have a little background on proofs and how to prove and disprove them, we go back to our two statements.
the thing with this situation is, one of them must be true (unless you're gung-ho on someone else holding dan's face while phil takes a picture on his phone of dan in his glasses, in which case, i applaud your commitment, but in actuality this proof will cover that option too)
the full statement we have is: dan is touching his face or phil is touching dan's face
now, because this is Real Life and we have a picture where a hand is touching dan's face, we know already that one of these options is true (as mentioned above) but! using symbolic logic you could also come to this conclusion.
this type of statement is an 'or' statement, and if you're curious, you can look into 'truth-tables' and see why, but at least one of the options must be true.
back to the proof at hand (bah-duhm-tss)
okay. now, proofs also must be 'general' in order to mean anything, really. these are statements of truth of the universe, not just for individuals. so, we will prove this generally.
we have 2 people involved, so individual 1 (dan, the owner of the face and potential face toucher) will be labelled as 'D' , and individual 2 (phil, the possible face toucher who does not own the face) will be labelled as 'P'. thus, this can be true for any such D and any such P.
so with our 'or' statement, in order to prove it, we pick one of the options and say that it is not true, and we have to show then that the other is true.
step 1: let's assume this is not P's hand. (assumption)
step 2: thus, it must be D's hand. (what we take from our assumption)
step 3: now, if it is D's hand, we look at what a hand on one's own face is capable of appearing like. (a definition or true fact about step 2)
the position in the given photo shows the hand with a thumb on the cheek, and a finger on the forehead. so, we find an example of a person with their fingers in the same position (or close to) and see if this supports our claim.
consider:
Tumblr media
now, with this image, you can clearly see how the subject's right hand has the thumb on the temple and index finger on the top of their head, however, it is a close enough position for our case.
from the view of the camera, the closest finger to the camera is the edge of the pinkie. in fact, it will always be the closest finger to the camera in this position, assuming the subject has all fingers and no additional appendages.
step 4: we now compare this to our photo (we verify if this holds to our claim or contradicts it)
Tumblr media
in our photo, the closest appendage to the camera is the edge of the thumb.
step 5: thus, it cannot be the case that D is touching their own face. (what the evidence says)
step 6: as we assumed it was not P's hand and have shown it cannot be D's hand, and as this is an 'or' statement both of these claims cannot be false, we can therefore conclude it must be P's hand. (our conclusion: re-stating the statement and assumptions and conclusion)
step 7: we verify that P is true (optional step but in beginner proofs you generally show why your case works)
to do this, i will show a picture of a person touching another's face, and compare it to our image.
consider:
Tumblr media
now, this image is not exactly the same, similar to above. however, P's left thumb is on the cheek, with their index on D's temple. the closest appendage to the camera (if it were in a similar perspective as our original) would be the edge of the thumb.
comparing it to our original:
Tumblr media
our comparison holds.
thus, we can conclude that the true claim in this statement is that P must be touching D's face, which, in particular means that:
phil is touching dan's face in the image
thank you for partaking in phannie mathematics. we now know. i am not sorry.
bonus:
phil has a hitchhikers thumb and dan doesn't so why was this necessary at all 🤡

computer science was a hoax from the universe to get me to study math in the pretense of ”hehe coding’s cool look at all these things u can do” *some mf vectors looming just around the corner* ”noNO dont look there; look here!! It’s ’hello world’ but in green heheh wOoOoo now it’s blue !! u are a god of this website” *matrices sharpening their knives somewhere*

Between commissions I finally managed to finish this OC set of parent characters! If the looks aren't enough to show you who their kid is, the background colors match them ^_^ but of course more details below!
Tumblr media
Name: Thuban
Name origin: The former pole star, before the north star (Polaris), it's name means "Large snake" and is referred to as the “Dragon's tail”
Pronouns: He/him

Pronouns: She/her
Age: -
Relation: Bella's mother, she raised her to be a warrior

Ethos (Power): Indomination (The ability to freeze the movement of objects and people, and lock them in place)

#Finn's ocs#Finn's art#oc references#i wrote the descs while w the kids so hopefully they make sense. my attention was split#but anyway here in the tags I'll talk about the designs in relation to their kids lol#polaris is emulating thuban moreso than anyone else. her color scheme and outfit motifs are the same as his- they ARE his#her original outfit is clothes she took and diy'd into her own so she could go off into the world and well presumably look for him at first#the truth is she always wanted to see the world that's why she loved maps. in a way this was an excuse. in another way she was just lonely#but doesn't understand loneliness. also the fact that she's not his daughter by blood is part of that#bc of her actual parents (not as relevant character-wise) she sees all relationships as temporary and she has issues connecting#ananke i wanted to mostly look intimidating in a way that Bella really isn't#Bella puts on skull hairties and fishnets and stuff but she's very much. a cute softie trying to look edgy. she has pink twintails#she's so different from her mom in pretty much every way but she still did have that ideal of strength drilled into her#still her take on it is softer. she's the team leader now but she's really pretty lenient aside from the important No Killing rule ofc#w Rhea and Arche i had a bit of a flower theme. pussywillow (lol) means motherhood and buttercups mean childishness#so. mother and child#but rhea is interesting bc she's raising a whole different kid now that she's in a different place in life#if you do the math she had Saiph young. and it was alright for a while until his dad (again not as important) died#so she didn't have support or money. but she had a connection to the guild because his dad's old sword teacher is a member (hmm)#but she was too scared/ashamed to visit. she just left him his dad's old knife because that's all she had (THE KNIFE IS IMPORTANT)#arche is her kid with her second husband and her new beginning. this will cause some inner problems for Saiph when he meets them...#Poerava was kinda designed to have rich lady vibes because remember Al's family is practically nobility#but more importantly she's designed to look like a mom. with the low ponytail and tired eyes#the black pearl of her namesake as the centerpiece of her outfit too#again she's got the healthiest relationship with her kid here by a longshot#but i mean don't worry Al still got the daddy issues so he's not getting away unscathed#I already drew Taurus with the zodiac knights though so i didn't feel the need to reintroduce him#anyway Mira really has 0 connection to any family at all she was found as an orphaned baby after a monster attack#obviously she had parents but beyond town of origin it's unknown who so she has no connections to any sort of past parental figure#the guild is her one and only family and that's how she wants it. she wants to be with them forever the past doesn't matter

Tim: you ever think about how when you’re scared of something— usually some kind of animal— someone will inevitably tell you that “they’re probably more scared of you than you are of it” and like, not only is that supremely unhelpful, but actually that might make it worst, because you know what scared things do? Do you? Because there’s a 1/3 chance they chose “fight” out of the “fight, flight, or freeze” choices and usually if that animal is a predator they’re going to go straight to fight
Dick: are you still mad about the thing with Damian?
Tim: he tried to stab me! And when that failed, he bit me! Yes I’m still mad about the thing with Damian!
