[@HeWhoComments]

Figuring it out is fun!

[@earthtoibrahim]

I have a thory, i might sound a lil stupid here but hear me out. So there are numbers and decimal numbers, and between each number there are infiite amounts of decimal numbers, for example between 1 and 0 there are infinite decimal numbers for example if we go down starting from 0.99 to zero, it goes forever, like (0.99, 0.98 0.97...etc) it never ends. So if there are infinite decimal numbers between two normal numbers, does that mean that there is also a point where we reach the end of infinite and enter whole another side of maths which is big enough for our brain to think about it? This debunks absolute infinite but since there are NOT infinite decimal numbers between two normal numbers, then there must be a point where we reach the barrier of maths and enter a another side of math. This theory also makes sense for dividing a number by zero, the number will be soo big even infinite wouldn't make sense as the answer. Let me know if im wrong.

[@TheMasterfulcreator]

@@earthtoibrahim between any two numbers of any kind there's infinitely many rational numbers (fractions). But this is a "countable" infinity. There is also infinitely many irrational numbers (non repeating infinite decimals) between any two numbers of any kind but this is an "uncountable" infinity. Uncountable infinities are really big.

These mysteries do nothing to make me like math. They take somewhat abstract numerical problems, whose solutions doesn't seem important, and try to visualize them into real world examples that break down in you think about the details. What's the largest sofa that can fit around a corner if we don't limit the sofa's shape to anything realistic for a piece of furniture? What's the smallest blanket that can wrap a linear creature that doesn't use blankets if we're not restricted to a realistic shape of a blanket? (Wouldn't the answer also change depending on the thickness of the blanket and the thickness of the worm?) Say you're lost in a forest. You have a map, but you have no way to tell where you are on the map so the map is irrelevant for this problem so I don't know why we brought it up. Instead we're going to walk in a random direction to get out of the forest, but whether we should walk in a straight line or a not depends on the shape of the forest. None of which seems to represent the reality of being lost in a forest.

[@effuah]

@@zunaidparker You have to prepare the blanket upfront, not knowing in how the worm is shaped and the blanket is sort of "stiff", so couldn't bend it. You can get below the circle by an ellipse to example. If the worm is stretched out you can use the long side of the banket, if it is curled up, it can't be that wide, since it is curled up, so the middle part doesn't have to be that wide.

[@malavoy1]

@@zunaidparker In the problem it's actually a curve, not a worm. Curves are lines, but the they are still lines, therefore having only one dimension. The Blanket that was the size of the worm would also be one dimensional, but the problem asks for the smallest 'area'. There are probably other restrictions on the types of 'blanket' that can be considered. These problems are usually all about the restrictions that are put on the requirements.

People usually look at decimal representations to investigate properties of the real numbers. In order to do that you almost always need a 1-1 correspondence between the reals and decimal representations. In order to have a 1-1 correspondence you need to exclude infinite 9's at the ends of numbers. While what you said is technically valid, if your looking to prove anything with these decimal representations then you probably need to define decimal representations with infinite 9's at the end as not existing. Or in other words .9999... does not equal 1, most of the time In short .9...=1 ... sometimes lol

Perhaps a bit too deep, but since we were discussing things that have not been proven. I'm not trolling, just nerding out.

[@blak4831]

We don't know and can't know, and that's honestly what excites me so much about math (and breaks my heart with regards to people who don't share in that sentiment). Your example of imaginary numbers is a perfect one - they're incredibly useful in the real world as they distinguish between different axis that meet certain properties, like the axis of 2D space or even abstract dimensions in non-spatial data sets. We have absolutely no way of knowing whether a crackpot idea will lead to a massive breakthrough or nothing at all, and that's what's exciting - there's a theoretically infinite toolbox out there that's all interconnected in surprising and nonlinear yet still rigorously structured ways and we just get to keep digging and finding ways to solve real-world problems we didn't even know we had

So there are numbers and decimal numbers, and between each number there are infiite amounts of decimal numbers, for example between 1 and 0 there are infinite decimal numbers for example if we go down starting from 0.99 to zero, it goes forever, like (0.99, 0.98 0.97...etc) it never ends. So if there are infinite decimal numbers between two normal numbers, does that mean that there is also a point where we reach the end of infinite and enter whole another side of maths which is big enough for our brain to think about it? This debunks absolute infinite but since there are NOT infinite decimal numbers between two normal numbers, then there must be a point where we reach the barrier of maths and enter a another side of math. This theory also makes sense for dividing a number by zero, the number will be soo big even infinite wouldn't make sense as the answer. Let me know if im wrong.

I feel like this episode suffers from not being in depth enough. I was intrigued and wanted to know a bit more about the math.

5. Why we won't ditch Pi and start using Tau, considering it's highly superior

Fun fact: Any mathematician lost in a forest will die because he aint smart enough to toss away math and concentrate on actual survival.

[@Cosmic_Cabana]

Sounds stupid. Probably right.

Now I know why engineering was more appealing to me.

[@markadams7046]

What about the question, "Is math discovered or created?"

[@user255]

Neither, the terms do not apply to such question. Or either one depending on how you like to define them.

idk when I stopped being subscribed to SciShow, but apparently I still watch you guys so much it was pretty hard to notice.

If you keep your palms let's say one meter apart from one another and you half that distance every time, mathematically your palms should never touch. But they do.

I understood nothing. Yet I'm amazed at how mathematicians made the modern world by goofing around.

Q: Is Math a field of Science?

[@toriad9848]

Physics, mostly.

[@ChrisChoi123]

no

[@YahyaFalcon]

No, not unless deductive proof takes the place of experimental evidence in all scientific fields.

@@toriad9848 Physics is mostly math, but it doesn't work the other way around.
