Proof That 1 = 2 - An Amateur Video Experiment To Enter A Contest. Have fun!

http://ProofThat1Equals2.com - Sort of a foolish video that, for fun, experimentation and a contest, tries to prove the unprovable. Have fun watching and feel free to share it :)

you almost sound like winnie the pooh

[RovaalRotemon]

No, that's uncle winnie, I'm rovie the pooh :)

Credit to OrphanEater1 for posting a somewhat different solution that I had in mind, but a solution anyway. Congrats!!!

[RovaalRotemon]

Within minutes, both aracir & heltskay posted the answer, so I'm removing their comments.

Anyone else?

[RovaalRotemon]

By the way, for anyone that posts the solution, I'll write a comment and will give you FULL CREDIT for solving it.

But I will also delete the solution, so not to spoil it for everyone else.

C'mon, who's gonna be the first one?

Easy, when you take two equal numbers and find the square roots for each, the two new numbers are not equal

[dackovg]

When you remove the square, the number can be both positive and negative, I think that's it

[glenjacobs423]

you are correct uptill 2:43....from that point onwards hence is the solution

(4-9/2)^2 = (5-9/2)^2 ;

removing the square roots we get

(4-9/2) = (9/2-5)

-1/2 = -1/2

the explanation lies in mathematical square fundamentals!

[natpeera]

(-1/2)^2=(1/2)^2

u cant sqr it

[3hlang]

It all went wrong at 2:33. (-1)^2=1^2 but -1 does not equal 1; you must take a negative root on one side for the equality to stand. Sorry.

I would just like to add, this video is quite neat, and I haven't seen this technique used before, so thanks for the upload, RovaalRotemon

I failed a level math yesterday go me :D

@GolldLining

The logical fallacy is in the square root taking step

(0.5)squared = (-0.5)squared

does not mean 0.5 = -0.5

Go back to school

@GolldLining

"4²-(9*4) IS NOT EQUAL TO 4²-2(9/2*4)

Do the maths:

16-36 NOT EQUAL TO 16 -72"

clearly 4²-2(9/2*4) = 16 - (2 x 4.5 x 4)

=16 - 36

NOT 72

I think you should go back to school
