Pythagoras’ theorem is incredibly useful when you are trying to make right-angle triangles. Since you generally want a house to have walls at right angles to each other, you can achieve that by just building a decently sized triangle that you can place into the corners. Apparently, not every mason knows this considering the ones that built our house screwed up and built the wall of angle to each other.
@christopherwatson8840

Carpenters (and others) use the converse of the Pythagorean Theorem all the time when they use the 3-4-5 rule to see if the corner they made is actually a right angle.

A straw has one hole. It can have many openings, or none (although, would it still be a straw?).
You can think of it like this, if you drill a hole through a block of wood, you have a hole with two openings. Glue the openings shut, and the hole is still there.
The real question starts when you drill another, intersecting hole.

If a straw with one closed end has one hole, then so does a typical dinner plate. Dinner plates that don’t have a flat bottom would typically have two holes. Leaving aside the formal topology arguments, this is a question of semantics and is strongly affected by context.

When I saw the thumbnail for this video asking how many holes a straw has my immediate reaction was to try to mentally topographically deform a ‘straw’ into n-hole toruses which I did to give me global topological property of a straw having 0 holes. Though to be honest since I was a kid I have struggled very hard to visualize anything in my mind mentally except for the most basic abstract mathematical ideas such as regular tetrahedron’s in n- dimensional space, such as hypercubes, hyper spheres, basically repeating patterns and shapes that follow well defined rules. But trying to visualize a tree or especially a person is more difficult for me. I wonder if this is related to my autism. I was always special needs in most of my classes though use to be a year or two ahead in my math classes. I remember always asking my teachers during recess and when getting on the bus in kindergarten and first grade for a math problem but I kept asking for ones that were more challenging like the square root of 36 or 25 at the time. Though I did eventually fail my first math class then fail it 2 more times before dropping out of after 3 and a half years trying to get my bachelors as a full time student eventually. I never did learn proofs sadly.

This guy may know his math. He may be a genius at that. But he is truly awful at being a math communicator. Not only is he heavily biased to a branch of math applications, he is painfully unimaginative. The first question he answered is very euro-Plato-logo centric. It totally misses the richness other cultures, other philosophies, other paradigms and systems, other creative interpretations bring to math.
Do you think the pitagoras theorem is only used to measure distances?! That is like saying that the number 4 was only invented to count apples. My dude, measuring distances may be less than 0.1% of the use of the pitagoras theorem. Vectorial analysis is a an invetion that transformed the world. Newton mechanics would be incredibly impractical without the PT. Electricity cannot be understood without the PT.

December 8, 2023 at 5:02 pm
Real life use for pythagorean theorem: You’re building a house, and you want to ensure (for obvious reasons, hopefully) that the corners of the house are “square” (90 degrees). A common way to do this is to measure the opposing corners in an X. If the house is a rectangle, then if the corners are 90 degrees, as expected, these two measurements would be the same. But what if the house isn’t a rectangle, or what if you’ve only built two of the walls and you want to check for “square”?
Measure the length of the two walls you’ve built (lengths a and b), then measure the distance between the ends of the walls (length c). If a^2 + b^2 really does equal c^2, then your walls are indeed at a 90 degree angle to each other.

@danielbass09
December 9, 2023 at 7:33 am
That’s not correct. If you pinched the straw you would close the hole and now it would be like a very narrow long bucket. The opening of the top of a bucket isn’t called a “hole” same for a glass for example. So if you picked a hole in the bottom again you create 1 hole again. So the correct answer is only 1 hole.

I always think of geometry as the study of spaces that have so much structure that they are interesting both analytically and algebraically(in that for instance, they have an inner product)

If we have a round piece of paper, it has 0 holes, now if we close it up into a balloon you’ve caused a hole to be covered up which means you have -1 holes, now make a hole so it’s a bowl now it’s 0 holes as -1+1=0, now create a hole on the other end 0+1=1, a straw has 1 hole. you could say there’s 2 holes as well, now let’s cut the straw in half and each straw segment in half over and over til we have infinite pieces, now we could say a straw has infinite holes, but if we are to say a straw segment has 2 holes, then the infinite straw segments combined contain 2x infinite holes.

So a 3D cube is six 2D squares joined by contact at right angles, but a 4D tesseract is only two cubes? And joined with lines (not by contact) and at no particular angle? Seems arbitrary.

If you walk out the front door of my house, around the side to the back then in through the back door, you go down 8 steps and up only 4. The floor of the house is level. There’s a trick of course, but find it. I don’t think you can. The real trick here is that these ‘distortion’ are everywhere, you just have to have the knowledge and insight to notice them.

@MrBlinky10101
December 13, 2023 at 12:10 pm
No way he just said a straw has 1 and 2 holes at the same time, and both sides are right. Hole is a topological term, and topologically, a straw is the same shape as a bagle, torus or coffee mug, and all of them simply have 1 hole. The example he gave of closing one of the “holes” of the straw to turn it into a water bottle is not a homeomorphic transformation, as you were closing tight 2 distinct areas of the shape. A water bottle, topologically, has no holes.
This is not a matter of opinion, it is objective geometry.

5:09 The straw thing just depends on your definition of a hole. If you define it as an opening through something, like a hole in your shirt, then a straw has only one hole. If it doesn’t need to perforate, if a pit in the ground is a hole, then a straw has two holes.
This probably rifts off the word ‘hole’ having confusingly similar but strictly different meanings in language and in maths.

The golden ratio, phi, occurs in nature because it’s the irrational number that is hardest to approximate with a fraction. It’s the “most irrational” of rational numbers and natural forms that use it have practical benefits

Hypercubes are used “for real” in many applications. In computer graphics we have chips that connect to four other chips…so if you connect up a lot of these chips to get more and more performance – you place them at the vertices of a hypercube.
@capoman1

2:53 SURPRISE. Framers use pythagorean formula to make sure a frame is square. Rather than use a square, they know the bottom and side lengths and then make sure the hypotenuse is the right length to wnsure it is square…. Granted a carpenter’s calculator does the math for them.
@ClonedGamer001

I think the issue with the “Does a straw have one hole or two?” is that everyone treats it as a mathematical problem when it’s more of a language problem.

For anyone who said you don’t use a Pythagorean theorem in life, go to the store and buy a ladder to climb on the roof of your house. Maybe you need to replace your roof, maybe you want to put up some lights, etc. Pythagorean theorem will tell you the shortest ladder you can get, where you can reach and still have a safely positioned ladder.

A common application of the Pythagorean theorem is to obtain a perfect right angle to an existing straight line. Something like marking the position of a fence using house’s exterior wall as one of the lines.

No, topology (the study of holes basically) says a tunnel is only one hole, as it cannot be removed without ripping or squishing parts together, watch Vsauce’s “How Many Holes does a Human have?” Which explains it in more an in better detail

How many holes does a straw have? How many holes does a jar have? It’s just a matter of definitions! The hole of a straw is NOT the same as the hole of a jar. The jar is a container, the straw is a conduit. Don’t try using a straw to hold anything for an extended period of time

In no way does changing the shape of the straw allow you to change the number of holes it has. It’s one thing to simply make the straw shorter but it’s an entire other thing to close and opening that it already had The argument you made could easily apply to a bagel. If I close to the bottom of a bagel it would become a bread bowl with a single hole in it but it would no longer be a bagel. Straws have one hole
