Alternative title: Michael having fun doing his hobby.
Michael is alternate Albert Einstein
This stuff is all just so lovely! I’m happy he does this stuff
I had no idea you could prove irrationality. Proofs are a mathematician’s witchcraft.
He likes it , but I ...
or does he?
*watches this instead of studying for math test*
same unfortunately, normal algebra is way more fun than linear algebra
Same, pre-calc test tomorrow
good luck, I bombed mine, hopefully you don't suffer the same fate
I just watched it after calculas II EXAM, this looks silly but reasonable🤔
I think you're mistaken... u don't need to study if you're watching VSauce
Proof by contradition is like kryptonite for infinity-related questions, isn't it
I mean, proof by induction is more so suited for infinity questions
@@unconscious5630 what’s proof by induction? I just started discrete math and I don’t think I’ve learned that one yet
@@joeman1063 It's basically the domino effect as a method of proof: If you want to show that a statement that somehow depends on a natural number n is true for all natural numbers n, it's sufficient to first show that it is true for n=1 and then show that your statement being true for some n implies it being true for n+1. In other words: you show that the first domino piece falls, and then you show that if some domino falls, the next one will fall as well. Therefore all domino pieces fall and your statement is proven for all n. One typical example for proof by induction is the proof of the closed formula for summing the first n natural numbers provided by little Gauss. Generally a lot of statements involving finite sums lend themselves to proof by induction, for example if you want to show that laws like distributivity hold in general for a finite numbers of addends.
Contradiction and Induction method are both same logically. Here your n is a/b , so it holds for any a/b and also a/b + 1 . So by induction this contradiction holds for any a and b ratio.
Interesting thing is that,..can we prove existence of God with this method???
I was taught this proof in school yet was somehow still entertained enough to watch the whole video. There is my proof that Michael is an incredible host.

Let's prove that the square root of 2 is irrational...
BUT FIRST! What is a number?
...and how much does a number weigh?
And where is it in time
Can I eat it?
It's odd to have even numbers..
... and how does it smell in space ?
Literally had this as a proof by contradiction question in a maths test and wanted to curl up in a ball
i really love it when these math videos give me a slight shift in perspective about something that is incredibly common/natural to me-, like, reducing fractions
i know in my head that 4/6 is equal to 2/3, easy, and i know that 4/6 can be reduced into 2/3 without changing its value. if you were to ask me _why_ the value doesn't change, my answer would be something like "because the ratio in relation to the numbers stayed consistent, the proportions of 4 to 6 are equal to the proportions of 2 to 3."
but here-, michael just gives the simple answer of "since both 4 and 6 can be divided by 2, we can divide this fraction by the fraction 2/2. and since 2/2 is equal to one, this is equivalent to dividing by one, which will not change the value of our number."
like-, "huh, that *_is_* true-, it is just like dividing by 1, never thought of it like that"
it makes absolute sense and shows a different way to describe the same thing-, it's so cool to me.
Your approach is essentially the geometric proof. Suppose you have two similar right triangles, one with legs of 4 and 6, the other with legs of 2 and 3. For them to be similar, the angles must match, which means the tangent of the angles must match. Since tangent is opposite over adjacent, which is 4/6 for one and 2/3 for the other, those fractions must be the same value.
The ancient Pythagoreans would have literally killed you for this act of heresy. They really did not like even the idea of irrational numbers. They drowned the man who suggested that pi might not be some divine ratio like 22/7.
Robinson Kaspar oh yeah like wtaf was wrong with people in maths and sciences back then?
@@nabranestwistypuzzler7019 the pythagoreans were more of a cult that thought rational math was the explanation to everything than what would be considered a modern style group dedicated to math or science.

Never realized that either... I’m French, irrational numbers are called irrationnel, but ratios are called fraction......

And today my friends we learned that... Binomial multiplication is Michael's favorite
Hs Sm wait until he figures out Pascal’s triangle in polynomial multiplication
(a+b)^2=a^2+2ab+b^2 ... ?
but he said theyre his fav in a vsauce video

What others see : (a+b)^2=a^2+2ab+b^2
Sardorbek Omonkulov
If you say that (a+b)^2=a^2+b^2, then 2^2 is (1+1)^2, so 2^2 is 2

SAP: Hey Vsauce, Davi Calazans here.
I have seen this proof maybe 50 times now, but no one gets as hyped as Michael. I love it! "OH MY GOODNESS GRACIOUS! IT'S EVEN!!!!"
At about 16:00 he says "since an even number squared is even, then if b^2 is even then b must be even". That is using the implication in the wrong way.
fr
The reason why it’s ok is because in the assumption, he said that a and b are integers. But yes, if we didn’t know that b was an integer, it would be using the implication in the wrong way.

I used to think the square root of 2 was just another number, but it turns out it's the sneakiest number of them all!
Its been more than 10 years since I left my school, and this video made me understand why multiply becomes divide on the other side of the equation and vice versa. I was never told why just taught what.
Sorry if I'm dumb but I don't really get it. For me the proof Michael shows at 5:55 only proves that an even number squared always produces an even number, NOT that the square root of any even number is also an even number. For example the square root of 6 isn't an even number, since by definition an even number has to be an integer (not a fraction). And this kinda ruins the whole proof at the end in my mind. Pls help me out. Edit: Ok I finally get it, for those that are still confused I hope this clears it out (thanks to FlamingJM for making me understand it fully):
The proofs at 5:55 indeed don't prove that the square root of any even number is also an even number, like I said. They just prove that all even integers squared produce even numbers, and all odd integers squared produce odd numbers. This means that IF the square root of an even number is an integer, then it must itself also be an even integer, (it can't be an odd integer since all odd integers squared produce odd numbers).
In the final proof at the end, we know that a and b are integers (because numerators and denominators in a fraction are always integers after all). Therefore since by squaring either of them you get an even number, they themselves must also be even numbers.
All of this means that if the square root of an even number is not an integer, then it must be an irrational number. Apparently this applies to odd numbers too. So the square roots of not just 2, but all other non-square numbers, are also irrational numbers. I only learned this now. Hope this helps. And as always, thanks for watching!
the square root of 6 is also an irrational number, just like the square root of two, so you've basically just discovered the same contradiction that Michael uses to prove that the square root of two is irrational
I thought we all knew that most even numbers have irrational square roots 🤷🏾♂️
Remember that he defined a and b to be integers. This means that a² and b² are squares of integers. While it is true that sqrt(a) is not necessarily an even integer if a is an even integer, we know that a is an integer, and we're squaring it to get a². So if a² is an even integer, we know that a (the integer that was squared to get a²) is also an even integer.
He doesn't prove that the square root of an even number is even, but rather the square root of c^2 (where c represents an even number) is even, which is common sense: squaring and square root-ing cancel reach other out and oh my God you have over a million subs
Another way to think about it is that, since he proved that all odd numbers squared are odd, and a² is even, then a is definitely not odd (he already defined a to be an integer) thus a is even.
the way Michael writes the number 8 is mildly infuriating
Ethanagor S-D that’s how I write 8s
@@SuperTurtle0 youre a bad person
Alexander Geppert not my fault I’ve always written them that way
@@SuperTurtle0 style, eh?
But it looks much better
One minor issue. The statement "a^2 is even implies a is even" doesn't follow from "a even implies a^2 even". It follows from the contrapositive of the statement "a odd implies a^2 odd".
In this case it seems trivial but the phrasing comes off as "A implies B is true because B implies A is true", which in general is NOT logically true. Converses are not equivalent statements, but contrapositives are.
Excellent point

@@padmanabanraghavendran3570 western education is optional beyond algebra and some geometry. Highschool usually has you take algebra 1 and 2, geometry, and trigonometry or pre calculus. After that, in college, a lot of degrees only require like... Calc 1 which is pretty easy, you learn derivatives, optimization, integrating, implicit derivatives, and stuff like that mostly.
In some majors you have to take more, like I am a CS major and i have to take calc I, II, III, and then either calc IV or Matrix Algebra. If i take two extra math courses which i can easily do over summer or something, I will actually be able to get my minor in math. All engineering majors are about the same in that regard
