That's amazing! Really clever!

Wow.

*gasp* !

i loled

5 me back christmasconan.ytmnd.com

never saw that technique... but very interesting.

WHOAMG! MINDf*ck!

I approve of this!

Very clever. It's an optical illusion, of course, but still clever.

+1

The squares must be changing size as they're shifting. Gotta watch again.

What the Fück?

I MEANT F*ck.

(head explodes)

Huh.

MINDf*ck

What you say!?

The diagonals of the blue shape and the green shape (and likewise of the red and the orange) in the 5 x 13 figure look like they match up, but they actually don't. There's a narrow gap between them, too narrow to see easily, but when it's added up over

+3

the triangles arent really triangles. 5'd for concept

LOL at ManuelHung trying to be smart: http://volokh.com/posts/1093524465.shtml

No, Manhung is right. Here's how it happens. When the pieces break off, the edge where it was broken gets thicker. But when the pieces are put back together they're put back with these larger pieces. This extra space, added up among all the lines, accou

+2

thats really cool

nts for the difference in area.

I know ManuelHung was right, because HE COPIED AND PASTED IT OFF THE LINK I POSTED.

WTF

Loving it.

TEH UNIVER IS IMPLODING!

i don't think the slopes are the same though =X

There is an area equal to one whole block missing smack dab in the middle of the diagonal "line." It is especially clear when they show the two blocks next to eachother.

enough of these chinese mind tricks! lol nice ytmnd. very clever

holy sh*t dude!

you have unraveled the fabrics of the space time continuum

The slope of the lines are 3/8 and 2/5 so they don't line up perfectly, leaving a thin gap which is hidden by the outlines.

had i not just figured it out after 30 minutes of cutting and fitting paper, i would've taken it to my algebra 2 teacher and looked really stupid. 4'd for *ssholery

What song is that, that is playing in the background? I really like it.

Yeah. If you look at the long diagonal on the rectangle, notice how the line is thicker in the middle and thin on the ends. It took me three minutes of staring to figure it out.

this is the first time this has ever been posted on the internet

The law of fives is never wrong.

WTF!? It's math.. on ytmnd!!! ONED!

Too much moon language

White it's all an illusion, still entertaining.

good lord if this gets 5s all around the world must be ending

why is this recieving massive 5's..unoriginal :[ cmon

Getting some original music instead of this overused horsesh*t will net you a 5 instead of a 3.

totally baffled til i looked up the answer. 5'd for the brainf*cking

Well Played.

1/5, its not true

-1

omg teh ski is faling

its an optical illusion. Check your rises over runs and you'll find that one of the lines is not a line at all and is not straight. Though it was very clever :)

Yeah, things don't quite line up, I tried with graph paper.

Owww my brain!

Time Paradox... ｷﾀ---------(º∀º)--------- !!!

Unlike 1=.99, it's not mathamaticly accurate, but it's a fun and clever optical illusion nonetheless.

Stop it! You're hurting my head!

What the hell?

Stop whining because it fooled you at first. 5'd for pissing so many people off.

WTF!? It's math.. on ytmnd!!! FIVED!

I wish some mathemetician would crack that already

wtf

Look closely how the lines line up on the second rectangle. Notice any discrepancies?

5 for making my bwain aspwode.

Old puzzle. The trick is that the sections don't fit together perfectly when re-assembled.

5'd for making n00bs go "zOMG MINDF*CK!!!1!1one!1"

The slope of the diagonal between the red and green triangles comes out to two point six repeating (2.67~). The slope of the diagonals between the blue and orange is exactly two point five (2.5). When the shape is repositioned, the gap between the shapes

(continued) does not make itself apparent to the viewer. +5 for presentation though.

very clever.

the formula for the area of a square is; A=S^2 and a rectangle is A=bh, points for creativity but a 2 for lack of mathematics

MINDf*ck MINDf*ck MINDF-- *explodes viciously*

SETTLE DOWN NERDS!

SOMEONE UPDATE THIS IN ENNGGRISH PLEASE...and then we might have a winner.

My mind just exploded.

OMGZZ MY BRAINNNNN

I just changed the music.

Sounds the same to me. Then again, YTMND is broken right now :|

Bah, not this optical illusion again. The two 5x8 "triangles" which make up the 5x8 rectangle are not in fact triangles. If you were to view a high resolution image of the two triangles you would see that they are actually quadrilaterals and not trian

I'm scared.

What the hell

Ill show this to my math teacher to stupify her

MINDf*ck

Wait...

Nonono... they are still triangles... no doubt. They don't fit together, realistically.

Notice: The slope of blue/orange is 2/5, while red/green is 3/8. While they are very close, they could vener fit, due to the fact that they are different slopes

lol @ people who suck at math.

awesome

mathowns.ytmnd.com you sunnava bitch

holy carp

1'd for crap loop of a great song it deserves better a hell of a lot better!! cuz fight club owns you in the face! and you got owned by mathowns.ytmnd.com

Doesn't work though, the slope on 2 of the triangles is 3/8 and on the others it's 2/5, that's not the same. YOU LOSE.

OH HOT sh*t. You used the loop from the 9/11 flash! Your 3 is now officially a 5. Yes. Inkdrinker gives 5s sometimes.

Have you considered making the background the same color as that yellow? It might look smoother.

fix the sound, pops a bit

http://ilikecheeeze.ytmnsfw.com/ Has better sound, too.

mathowns.ytmnd.com you sunnava bitch

Those are triangles. They're quadrilaterals. If you look REALLY closely, you can see that the triangles are either convex or concave slightly. It's an illusion. 1 for wasted effort.

Those aren't triangles*

hey what was the original song you used, before you changed it.

MINDf*ck

original song plsssssssssssssssss

Lol although this is confusing.

I liked it, showed my math professor, he says it's called a "Fudge" factor. Someone mentioned how the edges are stretched already. Lousy optical illusions.

Different dimentions. 8x8 as a whole square grid would produce 64. It's different when you separate them into pieces, since you get different results, depending on the way you cut the grid into pieces. More like logic, if you think about it. ;)

NO! THERE ARE FOUR LIGHTS!!!

FTW?

With the music as it is, I almost expect the screen to be interrupted by "MATH LEAVES WRECKAGE. IT MESSES UP THE GROUND."

Also, GCNMario must have failed math class.

5 because it hurts my brain.

I understand what the deal is. You create a small parallelogram with an area of 1. So 8*8=5*13-1.

thats pretty trippy.

Wow, just Wow

Would be odd if the corners matched up in the final rectangle, so 5'd for fooling all the morons who cant see.

AHHHHHH!!!! Here's some more mysterious math for you... 666 = jesus getting *ss raped by lucifer while he smokes a fat cuban

Everything I know is a lie!

wow, an interesting ytmnd that isn't a fad. good job sir. AND i fixed flashing hitler like you recommended connectfuhrer.ytmnd.com

wow

we all gonna die now?

This is better than Finding X.

wtf?

It's pretty easy to spot the error, even by visual inspection. 3/8 != 2/5, so the slopes don't match up exactly.

The joining angle of going across the oblong is not an exact fit. In fact, the gap it leaves is exactly 1 square.

amazing

would get a 5 if it said something about how it doesn't work. There are also way better false proofs out there.

Oh long johnson ... also cocks

What the.... someone set up us the bomb.

boring

You fried my brain. How come these balls are wet?

whoa sweet

universe tier!

that was awsome, why did you spend time finding this out?

Nothing special. Area of shapes after shifting location doesn't prove anything.

Now I'm confused... lol.

your stupid

Awesome find, I give it five stars, but unfortuantely, there is an explanation. *sigh* Anyway, the slope of the diagonal line of the triangle and the diagonal line of the trapezoid aren't the same, they are slightly off. When you put the two triangles and trapezoids back together for the rectangle, the diagonal line is in fact not a line at all, but a paralellogram with an area of 1. I'm surprised no one explained this yet.

ahhh mind f*ck!

gay, also not true

The fractional difference in slopes along the diagonal in the new rectangle add up to exactly 1.

Ahhh crazy!

its not true, do it yourself and the peices don't match up correctly. nt though

This ytmnd doesn't work, look at the website below: http://mathsrules.ytmnd.com

Yes?!

Mind = blown

No, but nice try.

What...the...f00k

You made me stare blankly at the screen after this ytmnd. Good j0rb.

Not really that good... Its like saying 02 has 2 oxygen atoms, then ya re-arange the protons and electrons and 'omg wow :O its changed!' -.-

the rectangle isn't really a rectangle. There is 1 square's worth of empty space along the "diagnal" which isn't even perfectly diagnal.

Well after all 0.999 repeating is 1 :)

Lines don't fit perfectly, all these f*cking gook math sites have either lines not fitting perfectly or lines not perfectly straight.

You fail. http://mathrules.ytmnd.com/ ftw!

Math still rules supreme. 5 for making the math major think!

You bring up an interesting point, and in response I say that.....

Im sorry but the angle of the hypontunses doesnt line up its just slightly off... FAIL!!!

Awesome, took me a while to figure it out too.

For a second I thought that was true. Oh well, we can't all win.

A very old math trick, but I like seeing it animated like that. BTW, the hypotenuses of each main triangle are bent outwards slightly (mathematically and barely visually).

saw this come up in YTMND Spy

5 for the Fight Club music
