This is a short, animated visual proof showing the sum of the infinite geometric series with first term 1/2 and ratio 1/2 using a 1 by 1 square. This infinite sum allows us to determine an interesting base 2 (or binary) representation of 1.

Thanks!

This animation is based on a visual proof by Warren Page from the September 1981 issue of Mathematics Magazine, (page 201 - www.jstor.org/stable/2689632 ).

In theory, could you do a similar argument to prove 0.99999999...=1?

That make sense and thank you for giving new information about infinite sum❤

I think you can also use a segment or a cube. If you can imagine it, you can also use a tesseract, etc

this kind of correlates to the achilles and the turtle pradox. achilles gives the turtle a 10 foot headstart but cannot ever reach the turtle because to get to the turtle he would have to travel 5 feet (1/2) but to travel 5 feet he would have to travel 2.5 feet etc etc. basically achilles cannot win the race because MATHEMATICALLY he needs to cross an infinite amount of points to reach the turtle

so 0.nnnnnnnn... =1 in base n+1? I know that's not the proper notation but you get the point

instead I can use more space without making any sense of it!

You’ve basically made this video several times already… 0.XXX… = 1 in any system that’s base-(X+1)

How can you divide above base 2 in base 2? Wouldn’t it technically be 1/10, 1/1000, 1/10000???

If I remember correctly ratio test proves this as well
(1/2) / 1-(1/2) = (1/2) x (2/1) = 1

I have a guess . 1/k + 1/k² + 1/k³ +... = 1/(k-1). Is that true?

Okay yes, on its surface, this is trivial enough to understand. But what does INFINITY really mean in that context?! You start with measurable Quantities (numbers) and you extend the limit to an immeasurable Quality (i.e. Infinity)! We are mixing mathematical spaces here. This is as crazy as saying that the infinite sum goes from k=1 to Aleph null.

There will always be a small portion not shaded because you are not filling in a full square each time. You get closer and closer but never reach a full square.

And you actually believe that? You are stuck in Zeno's Paradox and can't extricate yourself.
