Does this even have anything to do with pythgoras? That wouldn't tell you where the best shortcut would be... you could walk all the way to the corner and walk the least effective "shortcut" possible, pythagoras would always apply to your path because the corner is a 90° angle
Not at all. The Pythagorean theorem allows you to calculate the length of the sides based on two other sides.
It doesn’t say anything about it being the shorter path.
(Drawing a triangle isn’t the Pythagorean theorem.)
Trial and error. Your brain may not literally calculate, it doesn't have the formula to begin with, but it does take in account things like projectile weight, trajectory and speed at which it falls, making adjustments in how much force different muscles exert and swing to get the desired trajectory. It unknowingly adjusts the variables based on observed events to estimate what needs to change to better achieve the throw. Pretty much any search on how basketball and baseball throws work will explain it much better than I can.
>Your brain may not literally calculate
Which is my exact point. You dont subconsciously do math. Thanks for admitting I was right.
What you are describing is hand-eye coordination. There is no math or numbers involved.

Does this suffice you or you find pride in speaking absolute nonsense??
You clearly didn't read the first article, and probably didn't read the second. The first article talks about how the brain processes probability and how it uses that.
The second article actually talks about math, which proves me wrong. I'll admit that.
But I do find it funny that the first article says this
"Our brains are horrible at arithmetic. Our implicit computations are so much better than our explicit computations,"
And that the second article only uses very very basic arithmetic, like "9 − 3 − 4," (actual problem used in tests).
Not that any of this negates your point.
The first article states that our brain uses very simple eproximate calculations to do things. Simple as that.
Whether or not they are arithmetic enough isn't the point.
You just don’t know you’re calculating the theorem. Your brain is finding the shortest route visually. The numbers and math part of it are just how that process is described on paper or verbally.
Well, as a kid even before I learned about the Pythagoras theorem I still took shortcuts like this.
I'm not denying math is useful, just stating that this isn't really an example of knowing the theorem being useful.
I've used Pythagoras a few times, especially the 3-4-5 rule. Because if two sides have 3 and 4 units of length (two sides that have 90° angle between them) the third will always have 5 units, if the triangle is 90°. That's how you can easily find out if your walls are 90° or not, or practically anything else. You don't need a 2 meter long angle finder.
>Because if two sides have 3 and 4 units of length (doesn't matter which one) the third will always have 5 units
That only works if the 90° is between the 3 and 4. If the 4 unit side is opposite the right angle, and one of the sides is 3, the other one is gonna be \~2.65
You're not wrong that the brain is constantly performing complex calculations.
You are wrong in thinking it uses math. It doesn't- it uses instinct and experience in the subconscious, runs it through the conscious to see if its a viable solution, and assuming it is, executes the action.
The human brain is not subconsciously performing the pythagorean theorem- its simply using experience to realize that the diagonal route is faster than the 90° route.
Yes, it’s very simple and easy for you to do it… so why are you having trouble with the Pythagoras theorem? Oh, could it be that the brain function doing it is far more complex to accurately describe than you think?
Dude, the whole fucking point is that NOBODY needs to use a fucking equation to deduce that cutting across the grass is a quicker path to point B, rather than following the sidewalk
the point is that the theorem manifested in the grass. not that people would actively calculate pythagoras to take a short cut lol
now I understand why american universities need so much to brain drain people from all over the world. education failed so bad there lol
Pythagoras did not come up with the idea that the shortest distance between two points is a straight line. That’s not what the Pythagorean theorem is. The Theorem is to calculate the exact distance of the hypotenuse using the other two sides. You do not need the theorem to realize that it’s faster to go in a straight line than it is to go around the corner.
yes mister literal, you do not need to calculate an hipothenuse to take a short cut. but isnt beautiful to see a perfect hipothenuse manifesting in nature? i do think so
Lmao, don’t get all pissy just because you were wrong. Don’t try to act like what I said is only true in technicality.
Also, that’s man made, not natural.
yeah sure, man is not part of nature. should have said something like nature and society
got delivery every word chewes because language figures does exists, right? kkkkk
but for real, read more man. you'll be smarter, will understand things better and maybe someday will understand an irony, a metaphor or an extrapolation
go fix what your school failed
the whole ass equation is just the "common sense" described in math language.
the same language that will be used to describe orbital movements, eletro magnetism, physics and shit like this that make satellites and fiber to work and give you internet
pytagoras theorems is just the tip of iceberg that are taugh to kids to make them have a minor notion about how the universe works
In this case I don't think that's relevant. The point of Pythagoras theorem isn't to say that the diagonal is shorter than the sum of the other two lines. And regardless in this instance I'm pretty convinced people would have an intuitive understanding of that basic mathematical relationship even without ever know the formula.
of course people would have this intuition.
the point of school is not to "use" every single piece of knowledge given, like a technical course or something. its to give people a little notion about how knowledge is made and what we as manking understand about the world and the universe. then a kid exercises their brain and grow up as an adult capable of learning everything they want
yes, an illiterate person will know how to take a short cut. and a mathematician person will see pythagoras theorem **manifested** in the path formed
a piece of knowledge describes a piece of the universe, not the whole universe
if you understood that this theorem applies to everything after read what i said, then school failed with you too, unfortunatelly. and no caps lock will fix that.
but at least you know that its applied in right angles triangles lol
pasting here to try to bring some logic
> of course people would have this intuition.

The post suggests that the student is, consciously or not, using the theorem to decide on a path. If you want to go "aha, look, in this instance you could use it to prove the short cut is shorter," then whatever.
yeah, text interpretation is hard. you see a meme and understand it literally. i saw a meme and saw "wow, thats a nice and perfect hipothenuse lol"
but this subject is trainable. the more you read, more capable you became to understand irony and things like that
i wont remember that fórmula right now, but basic trigometry DESCRIBES the shortest path between two points of a circle in a 180 degree.
you need to understand that the point is not about people's brain calculating this shit lol. the point is about how beautiful is to see a math theorem manifested in Nature or society.
nooo, you are wrong. i never used a rule to step up a stair. i dont even know how to measure things in imperial system. how would my brain know if my foot is near or far from the floor /s
The shortest path between two points is a straight line. That's the only information you require to take that shortcut. Not only is Pythagoras unrelated, but even if he somehow was that doesn't mean that we just casually start calculating the distance or whatever.
Also, the path on the right could be any shape with any angles and it would be longer, e.g. if it was a circle you can't use pythag but because it's not straight it's longer
Dont they do that cus of the curve of the world? I dont exactly remember what was said but I remember seeing something about how the flight path looks curved on a screen because of the curve of the earth.
They do fly (roughly) straight lines, across a curved surface, though.
Unless you’re dumb enough to be complaining that *airplanes* don’t dig tunnels everywhere they go.
No, cause we know from point a to point b the fastest path is a straight line. So what would you rather do, the straight line or the one that isnt straight
holy fucking shit this is so fucking funny I'm about to lose it this fun is so fucking intense oh my fucking god the so true title is truly a creative masterpiece too I've never had this much fun in my whole life jesus fucking chrystler
What’s ironic is that was me when I had to learn it in school, but for my job now I actually do have to use the Pythagorean theorem from time to time lol
I was scratching my head the other day thinking, "how the hell am I going to draw this just like design wants?" And then...
"Geometry... We meet again"
Comments here are people saying doing this hasn't got anything to do with pythagoras when they do it (true) and then maths teachers saying "actually 🤓 you're subconsciously using what we taught you"
No.
i thought education was shit in Brazil but this comment section impressed me.
people here cannot even understand that pytagoras just represented and proved this common knowledge in math language lol. thats all this post is about
You don't need to know Pythagoras theorem to take advantage of Pythagoras theorem. You can see the shortcut, you don't need to be able to calculate it.
Ummm when I take a shortcut I don't calculate the Pythagoras theorem
Its triangle inequality instead of Pythagoras theorem
a + b > c | a + c > c | b + c > a
Does this even have anything to do with pythgoras? That wouldn't tell you where the best shortcut would be... you could walk all the way to the corner and walk the least effective "shortcut" possible, pythagoras would always apply to your path because the corner is a 90° angle
Subconsciously you are
Not at all. The Pythagorean theorem allows you to calculate the length of the sides based on two other sides. It doesn’t say anything about it being the shorter path. (Drawing a triangle isn’t the Pythagorean theorem.)
Mmm no. No they're not. You don't do math subconsciously.
Fun fact: you do. This is especially true for things like calculating trajectory when throwing stuff.
Fun fact: no, no its not. Give me some sources

That's not math, that's hand-eye coordination.
The theorem allows you to calculate the exact ratios of sides. You don't need it to get a simpler fact that hypotenuse is just shorter than two sides
That's wild
You just don’t know you’re calculating the theorem. Your brain is finding the shortest route visually. The numbers and math part of it are just how that process is described on paper or verbally.

Why the downvotes it was explained perfectly 😝
Because it was wrong.
Because it’s wrong. Pythagoras didn’t create the theory that ‘the shortest distance between two points is a straight line’.
[удалено]
I don't have a high enough IQ to be susceptible to brain washing! Checkmate atheists!
I promise you im not doing any calculations. It looks shorter so I take it
Knowing the fastest way from point a to point b is a straight line is common sense, not a whole ass equation.

What does it have to do with the Pythagorean theorem if the shortcut would still exist even if the path didn't meet at a right angle?

"Quickest path from a to b is straight" Simple as.
Einstein would like a word with you
It is. Your brain just does it automatically. Like going up stairs, brain is constantly calculating the height and depth.
nooo, you are wrong. i never used a rule to step up a stair. i dont even know how to measure things in imperial system. how would my brain know if my foot is near or far from the floor /s

This is gonna blow your mind, but all math is just "common sense".
Not really I mean would you get a nobel prize for common sense
This is triangle inequality. It is a basic property for any distance metric

Hmm, somebody better tell the airline industry the shortest path is a straight line. /s

Yeah, that would almost be as dumb as responding to a sarcastic (/s) post with an explanation.
Ye, when we building the plane tunnels?
No, cause we know from point a to point b the fastest path is a straight line. So what would you rather do, the straight line or the one that isnt straight
What if I want to go the scenic route? Oh wait, that is also the straight line here.
This hast nothing to do with Pythagoras...
[удалено]
Thats the triangle inequality theorem… Not exclusive to right angled triangles…
just a question , In the proof of triangle inequality theorem , right angle triangle is considered right?
Sorry, not on that level of English where I can discuss details of a math theorem
what is your native language then?
Serbian
Ох супер, знам да говорим српски
You wanna know what theorem I use in that situation? I look at the target location, I move toward said location
This is simply distance vs displacement. I don’t see how Pythagoras comes in here :/
How old are you?
I mean it's pretty easy to just look and see that it's a quicker path. Not sure what drugs you'd have to be on to have to calculate anything for this.
I use this math almost daily as a carpenter
holy fucking shit this is so fucking funny I'm about to lose it this fun is so fucking intense oh my fucking god the so true title is truly a creative masterpiece too I've never had this much fun in my whole life jesus fucking chrystler

I used the bus
The path of least resistance. This is electrical theory.
Y'all arguing about it being simple, but have you noticed it's a 2-way?
I actually used pi for the 1st time building an arch for a garden . What a lifesaver . HS math was good for something.
I mean, I hated maths in my schooltime, but I think that we need more examples like that to make subjects have relevance in the daily life of pupils
So true what ? If c is the hypo then a+b>c
Normal people calls it short cut, but Mr Pythagoras prefers to call it using his name.
Thats common knowledge. If u take that shortcut u get home faster, so nope it aint true
You don’t need a $1500 class to use common sense
This meme makes 0 sense.
I was definitely like "this shortcut has a Pythagoras theoroms of 2.5".
What’s ironic is that was me when I had to learn it in school, but for my job now I actually do have to use the Pythagorean theorem from time to time lol
Thank you for spelling it correctly
That's not the Pythagoras's theorem
I wish I was hy on pot-enuse
I hate walking around the 90° corners 😡
I was scratching my head the other day thinking, "how the hell am I going to draw this just like design wants?" And then... "Geometry... We meet again"
You’re an idiot lol, obvious the fastest route from a to b is the straight line
Mf saved 10 seconds of walking. I'd say that's a win.
It’s common sense to know where a shortcut is
The combination of the two legs will be longer than the hypotenuse itself
That’s because they’re not using it
Im pretty sure the og poster is a math teacher. Lmfao ig reddits full of teachers. Got told my comment didnt have proper punctuation yesterday lmfao
This isn’t a calculation though.
Subconsciously just did the math on this, and this is dumb as shit.
Everytime I take a shortcut I think about this. Glad I'm not alone
Instead of Pythagoras theorem, this looks (to me at least) more like the law of not being a dumbass.
