How big is infinity? - Dennis Wildfogel

Using the fundamentals of set theory, explore the mind-bending concept of the "infinity of infinities" -- and how it led mathematicians to conclude that math itself contains unanswerable questions.

You know what makes me really sad for some people who made great discoveries?
When people reject the person's idea and insult that person, leaving that person to spend the last years of his/her life in misery, and then people finally accept it until AFTER he die.
Then his dead, depressed body gets a Nobel prize.
Then it's already too late.

"No matter how big a number is, it's always close to zero than to infinity".

Educational content like this is slowly making the world a better place. I really wish videos like this existed when I was in grade school. Thank you 🙏

TEDed: "How big is infinty?"
*Me as an intellectual: "Ask the night manager."*

You can take infinity out of infinity infinite times and still left with infinity.

How big is infinity? Hint: Bigger than 5.

5:47 god.... that's the most visually n aesthetically pleasing thing i have ever seen in my life

This video is making sense and it's blowing my mind.

Mathematics is not the one who has limitations. We are

[proton]

how big is infinity, simple think the biggest number you can think of and add even the smallest value you can think of to it. keep doing until your mind exploades

[TakuroSpirit]

I guess some infinites are bigger than other infinites.

How big is infinity?
Me: it's infinitely big

This is one I'm going to need to watch a few times. I've been pausing this so much the first time to digest something then pow, the next reality check comes in. Great way of showing this mathematical conundrum.

I have always struggled with the concept of how one infinity can be bigger than another infinity.

If you'd be my Maths teacher I'd probably have better grades.

[AbhipshaSahuCoPrezIOFA]

so... basically "some infinities are bigger than other infinities"

[TheJonaii]

When your just on 4th grade and you already have a existential crisis.

[saman]

Here, let me simplify it.




Pretty damn big.

How do we interpret infinity?
TedEd: A pretzel.

[Chocolatebutterjelly]

Well now I just feel really bad for Georg Cantor. That faint sad expression at 5:39 just broke me.
