no no no no no no no no no no no

see it both ways

Can you put a black hole in the middle

7:02 Wtf, I had no idea artists did things like that back then. (Even in the modern day, I have no clue how anyone makes these by hand.)

For the window one, I can switch between seeing and not seeing it more or less at will, to the extent that it feels like I'm doing both at the same time. It's slightly less challenging to me than switching the direction of the ballerina silhouette.

Just wow just 😲 how I don’t see the rotation what I a Subbing

3:28 ruller is in 4th dimensions

when i rewatched the video i could control how i saw it :0

I only saw the small on oscillate. The bigger ones all rotated

Incredible

if u focus on the edge and think that it is rotating not oscilating u will see it rotating!

If you can't see it rotating then look at the top left square and focus on the top right corner of it and only look at that and it should work

The cool things is that I couldn't see it originally but now I can see both

Irl glitches

idk I can normally see the paper rotating if I focus enough.

That thing is non-euclidean

When there is nothing interfering (no rubics cube or ruler etc.) I can only see the oscillation. When there is an interference I can focus on the small edge or a corner and force the rotation to appear most of the time (my brain is probably using the information provided by the interference to correctly resolve the object). The midpoint where it 'switches' is the single hardest part. If you can maintain focus on the point you can get through it, but man it takes focus. Love the brain workout!

14:48 the most amazing -- and discombobulating -- illusion of all

11:40 do I see it oscillating? Or revolving? I dunno but I do see a dude grunting in pain! 😂

Wonder if the Intaglios or similar flat long depictions of humanoid shapes are anamorphic, to be viewed from a small distant hill or rise...

Oh man, The Curiosity Show! Now that's a blast from the past!

It honestly makes me kind of mad that I can't get myself to not see the illusion.

I noticed it's easier to see it rotating when one eye is closed

Left eye dominant, i could ascertain the illusion at the quarter turns and i could feel my left eye strain while my right eye essentially stopped working.

Best Video Man i am so glad i watched this. I kept my EYE on the RULER and then i could tell what was actually happening but just for a moment then it went back to the illusion

Does not work for me - i see the rotation. Maybe because the sheet is slightly curved/bend ..

The only time i kinda saw the illusion is with the round version. In all the other cases i just saw it at it was: rotating. And its not just this optical illusion, in fact only 1 tricked me: the impossible buildings someone made in Lego with water. And it was working.

Forced Perspective...

Got it with the ruler....aaaand lost it. Then got it again. Then...damn it!

The data "do" not discriminate. I appreciate this point.

Thanks for the headache and nausea

At first I saw it rotating and now I am trying to look how is it oscillating.

If you guys still can’t see it, try looking at the one at 4:07. It’s way easier to interpret.

I saw it! I actually saw it!!!

Dereks's channel will always be THE top science channel for me, hands down :)

on the big one i can see it spinning no problem the smaller ones are hard

Exce11ent work!

I am way too high for this...😂😂😂

The da heer circle wasn't as good, I mean i was fooled but then i noticed the point rotating and it sort of ruined i for me

I'd love to see these in video games...

"I'M GOING TO TURN MYSELF INTO AN OPTICAL ILLUSION MORTY!"

When you attached the rubik's cube to the thing, you thought it'll be less confusing. But it actually got worse.

Great ad! I plan to buy it!

This is soooooooooo cool 😎 Iron man haha 😂 ! I love this so much! You nailed it!

So strange. I saw you rotating but the window still seems to be oscillating.

This is crazy. Cool though! Halfway through if I paid close attention I saw it for what it is but as soon as I took my eye off it it did the weird but common illusion!

Took me 30 minutes to figure out to see it rotating

Thanks

My brain hurts after watching this. It feels like it had to jump through all kinds of hoops.

You have officially broken my brain.

You should look at the McGurk effect on speech. We perceive what we think is reality, but it can be far from it.

Just curious if you could do an episode on the ethics of using a VPN to circumvent the terms of service of streaming services. Or maybe explore, from your point of view, how you would be impacted if you made educational videos available for free to sub-Saharan Africa by charging a modest fee for it here in the US, yet someone else encouraged folks to use a VPN service to consume that content by appearing to be from Africa. I know it isn't science per se, but it is philosophy, and you always give us a good dose of that as well.

At First i didn't saw it till he told my Brain how it's supposed to do.

The ruler actually makes it easy(ier) to see past the illusion. Visit the Termesphere art gallery near Spearfish, SD. The artist paints on globes as if looking out from the inside. Very cool.

Looks like oscillation to me.....and quite the Christmas ornament as well... cool.

If you focus on the top left corner of the window you can perceive the image actually turning instead of it appearing back and fourth.

VE. 420??? You are a stoner? I didn't know

Yeah bud . I don't care about any of this

Do you think that's how our brains would interpret 4 dimensional objects? Constant optical illusion

Only some ppl can see... So who can't see it? I see the illusion. So wtf does that mean

My Eyes hurt! Hahaha

I stayed to the end!!! Oh the irony (Fe-ony) hahaha!

when you do see it (because the construction of the window is a bit wonky), you can no longer "unsee" the actual rotation - kinda spoils the fun for me a bit but you gotta love whoever thought this up! :)

my brain is ded now yes 2021 E

I can see through the illusion.

Ha, I see the world from one eye... just try to manipulate my depth perception! The faces are actually a extremely easy case to determine depth, inpression has a receeding jawline due to the blocked off decline of the chin, so it easy easy to determine depth based on the position of the chin, aswell as the inverted shadows caused by light. Beating this illusion is no different, Looking through the illusion and focusing on what information can continue to be seen within/around it, how much of the background perception is blocked, abnormal interactions with light, and most importantly shifting "depth" of the object itself particularly when it reached a parallel position to the viewer losing all depth. As for the skull painting. I simply see a skewed but clearly skewed skull at all angles from the start, but I suppose 2 conflicting inputs from your eyes may result in a distorted blur to some... Akin to the 3d image's that require 2 crossing points of view aimed behind the image to see , which I simply can not at all. When your brain has been trained to utilize all this consistently reliable information RATHER than rely heavily on the use of the 2 (trained but still ultimately random) crossing points of view to gain a false estimated perception of depth which is technically an illusion itself, you can easily see through these illusions attempting to exploit said interaction. This is actually why humans have a superior depth perception with one eye closed, however in general practices the offset of pov will leave most people disoriented in normal activity. But when orienting a object which you can center at the eye, that is no longer a issue. This is why shooters are more accurate with one eye in most cases.

That’s fun to watch

I see both. If I look directly at the window it looks like it moves back and forth but if I look at just one end it looks like it rotates. I have an autistic brain so maybe that's why I can see both I don't know.

Cool i an some people.

this gives me such bad anxiety i can't watch

Neuroscience suggests something more startling: 👇👇👇 This processing happens *ABOVE* your level of consciousness. The brain *decides* what to show you. The actual images are correctly processed on the "Center-Surround" receptors of the retina. Logic tree of these receptors is as follows: (On/Off = Off/On = ON) (On/On= Off/Off= OFF). It's *after* this basic processing that the brain compares it's results to statistical likelihood of previous experiences. That's why children must develop the ability to do this, and aren't born with it: There is no statistical data to draw from. The brain makes many guesses when 2 equivalent possibilities exist. (The LGN is at play here also.) It's the ambiguity well *after* processing that gets resolved here. A super-conscious selection among choices. (We know this is the case, because "color" is a component of this particular illusion, and is processed very late in the system, at V4). All evidence points towards a *Super-Consciousness* making these decisions. For one: the electrical impulses of nerves have been measured, and found that decisions at the neuron level are made *before* your conscious mind is aware of them. (Voxel cell bundling, like 3D pixels, make decisions as groups). All of the basic shapes and orientations are processed in layers, starting with simple constructs and adding texture, hue, and color afterwards. (V1-V2-V3-V4, in the occipital lobe). It's only after the brain is faced with a statistical anomaly, that it compares the data to statistical history, and resolves the conflict. This mechanism is present in illusions of this type. With practice, the illusions can be chosen between. This is essentially your brain asking for statistical updates from your satisfaction with your experience (effectively a comment card). So the big news here isn't the illusion, it's that humans have a Super-Consciousness. (At least that's the part that has changed my understanding of "Reality". But don't worry, you get used to it... Sort of 🤔)

Be curious. Always ask questions. That way, when you encounter something different, you can draw on previous experiences and statements to formulate your own idea of what might be happening. Thank you for the video!

I've heard this will be patched in a future release

At first i saw the illusion but then realizing it was wrong i tried to make my brain work differently and eventually managed to see it rotating. Its just like that white/gold dress that was actually blue/black. If you practice a little you can get your brain to see either :P

I can only see the reality if I intensely focus on one single part of the illusion, while also constantly trying to see the rotation as I **know** it is happening. And even then it doesn't hold very well. Staring at the end that is rotating towards me helps, as does staring at the bottom where the paper connects to the rod holding it up.

I still see it only rotate

i see the true rotation but there is a moment where the small side is tricking me forst like 300ms

I can see rotation on the "de Heer Circle" but the window illusion was actually making me angry I couldn't stop it from happening lol..

I am impressed.

This was beautiful

I only saw rotation on the first giant clip of him in it, after that I couldn’t get myself to not see the illusion 😭😭 even though I could get myself to see the rotation in both directions of that other commonly shared illusion of the girl’s shadow rotating with one leg up

and 2.7K people still doesn't get it LOL

The most interesting thing is that we can't reprogram our mind to correctly perceive the illusion, despite our conscious mind knowing full well we're being fooled!

Disillusion works much better on a screen because you can't see the three-dimensional depth to it

i can see it, anybody else? I mean i can see it as an illusion but at the same time, i can see it is not. its like 2 men thinking in the brain that an illusion meant to be an illusion but it's not

Cool

Absolutely loved your outro before the sponsor.

Trick to bypassing the illusion is to not focus on the surface but just the shape. Doing this will create a trippy scene where the shape is rotating but the surface is oscillating.

My brain hurts

At 2:38, you had my curiosity, now you have my attention

i can switch between seeing the illusion and not, dose that mean i have a high iq?

I relay didn't like it when you made me laugh with your pun. Please explain why? 😁

This video unrectangularizes my brains.

"I turned myself into an optical illusion, Morty! I'm optical illusion Derek!"

Ok wow... I dont know how i can easily precieve whats happening here. Let me help you... Try imagining the blue colour anf a drawing on a card. Do not precieve it as a 3d shape.

Ok wow... I dont know how i can easily precieve whats happening hete.

During the video I thought to my brain "hey I don't think that's right"

So is his shirt element a joke, wrong by numbers or something?

God!! I know the fact that the cube is oscillating but I could still see them rotating. It's magical but annoying 😵😵

Once I saw it the right way I couldn’t un-see it
