Dude, the example with the rubix cube absolutely broke me. Even if you try to cheat and look at an edge it still tricks you. The Curiosity Show is a goldmine!
Made me kind of nauseas.
Must be what HP Lovecraft meant by non-euclidean geometry.
well hello there are we going to be seeing this in one of your next puzzle boxes ?
The only way I could help my subconscious understand, is if I pause, and frame by frame tell my subconscious side what's going on..
Try looking at the small end of the rotating object and force your sight to see the rotation. It doesn’t work every time for me, but got it to work a couple/few times.
When you try to think outside the box, but your brain is the box
Well I guess I can stop working on.… exactly the same video 😂🤦♂️
lol, hopefully you'll get a lot of likes here
Hey, how you doin
It's okay just cite this video, make sure you're using the Harvard referencing system

Lol
The Ames Window Illusion is just so mind-boggling to me, no matter how much I tried to trick it, it always seems to me that it is oscillating.
Try looking it on in front of you so you see it as 3d, not some flat screen.
When I first watched it. The very beginning, I was able to watch it rotate 100%. The second I heard the host say it was an illusion and oscillates, then I couldn't go back. Kinda frustrating now lol
“My Brain prefers the illusion, rather than what’s actually happening”......if this isn’t 2020 in a nutshell lol

@@physicschemistryandquantum810 So you’re the Indian guy from TH-cam that our teachers show us?
Once learning exactly how it works, I can see the rotation if I really focus, but it takes real mental effort. Such an awesome illusion.
That’s the entirety of the human experience in a nutshell
@@Zelmel Yeah.
This has gotta be the most disturbing illusion I have ever seen, no matter how hard I try to beat it, it gets me every time.
What is most disturbing ? the fact that you're consciously trying to beat the illusion but you can't, or the fact that even if you try your hardest, your conscious self will never be able to outrule your inscouscious self ?.
@@DrakyHRT true
same
I got it the first time, but now I cant get it
I was able to beat it after a little bit of focus.
Finally, at 11:50 I was able to watch it rotate again. It is all about lighting.
You’re right I could see it rotate there
Well illusions are always about something smh
I first became aware of this illusion while in person at Six Flags in Atlanta, Georgia back in the early 70's when, after stepping into a "Room", the perceived perception of depths & distance conflicted with my natural understanding of the world. I was maybe 11 years old back then and the illusion imprinted on me. Thes explanation from this video helped explain the perception.
The "Ames Room" was named for American opthalmologist Adelbert Ames, Jr., who also created the first illusion.
Yeah
What's even better is when you can consciously "switch" the illusion on and off in your mind. Or essentially see both perspectives at once.
Thought I was the only one
@@benjamin5370 same

@@MrBej Are people NOT getting the joke?
Btw: I don't watch on a phone.
The only time I was able to see it NOT oscillating, was toward the late middle portion of the video ( 11:58 ) , when you were showing the jumbo window spinning, shot from outside of your (real) window. I was able to follow the under/bottomside of the lower corner of the short side in a full 360° spin. If I diverted my attention to any other portion of the spinning window, it appeared to oscillate.
same
Same man
Supposed to happen
Same
Yet the cable holding it up didn even complete the rotation?
For some reason (possibly just memories from the first time I ever saw it), I always see the skull in the painting as a skull, just warped like it was skewed in Photoshop. Honestly, just impresses me that Holbein was able to do that with paint.

“Finally, inner peace”
I saw it rotate after he showed the big window with natural lighting. Before that I had no idea how it worked.

Same here. However, if we're never told that the window is actually rotating, we would never know.

sorry pal i knew it was 2d really fast :') between the camera angle and the light reflection it jsut gave it away
When you attached the rubik's cube to the thing, you thought it'll be less confusing. But it actually got worse.
It gets easier for me
I could see the normal windows as 2D
@@lavinissensonthecommenter4197 cool? That’s not the illusion tho
Genuinely.
@@gabrielrabelo4968 wat?
One of my favourite illusions. I love how the shorter end tricks the brain and mind into perceiving back/forth; when my eyes clearly see the short end coming towards me/the screen. I find following the short side allows me to perceive the rotation and break the illusion. Also, my method works even better for me being tired af, so my noodle isn't opperating as properly as it should and allows my eyes to be able to catch the spinning, exnaying the back/forth completely.
With the big window, I actually perceive it as continuing to rotate up until the moment it's edge-on. After that, my perception flips, and I see it coming "back" from an oscillation that I never saw in the first place.
Same for me. Most people see it go about 180 one way then 180 the other. I see like 240 and then 120 which looks even worse because it just suddenly switches ossalation mid spin
I love how this guy tricks us into gaining knowledge.

What helped me was not taking my eyes of the wire connectors at the top as it was rotating in the room at 12:00. Good thing, otherwise I would have to consider that: 1) alternating current is actually circular 2) Michael Jordan played on an Ames Basketball Court all those years.

Version 42.0
I wanted to search for "Ames Window Illusion" when I heard Alan Watts talking about it in one of his lectures. The description didn't prepare me. It's really quite remarkable, particularly with Derek hanging halfway out of it.
I can briefly break the illusion, but the lighting inevitably makes my brain trust the illusion more. Even getting this far required an enormous amount of mental thought to convince my subconscious that the shape is not doing the seemingly obvious. Very interesting!
After staring at this for a while, I can see the rotation on the big wooden versions, but the paper ones still kill me
I could see the rotation with the ruler after a few seconds
@@spacenomad4477 I can see the rotation with the ruler after a few seconds, but only up until the point where it is parallel to my line of sight. the moment I start to see the side of it again, it flips to where it would be if it were swaying.
If I focus on the big side, I can watch it rotate around the front, but it flips when it gets to the back.
If I focus on the small side, I can watch it rotate around the back but it flips when it gets to the front.
I didn't have the same struggle with the round version.
I could see the paper one if you focus on the curve of the paper
I had the same thing happen with me with most illusions I can just tell myself what going on or look at it long enough and it will stop happening but with the paper ones it just doesn't work for me and I can't see it rotate no matter what I do
If I really try to see it I can, but the ruler still stumps me
Ruler: Seamlessly slides through matter, which is impossible
My Brain: I'm ok with this
Not necessarily impossible

@@Scribe13013 Hey bro, this is not how you advertise your music. Try another tactic.
I'll be laughing quite a while at that remark. thanks!
I like how your brain is forced to chose one of two impossibilities....
Either this window _isn't_ perfectly rectangular.....OR.....solid objects _can move indiscriminately through other solid objects._
And everyone's brain goes with option #2. I guess our brains just cannot FATHOM a window not being perfectly constructed. Why, that would be impossible. Objects travelling through each other though? Sure, why not....there's a first time for everything.
Way to go brain.
A rare creation that keeps getting better and better all the way to the last sentence..

Thank you for shouting out The Curiosity Show
I'm screaming at my brain: "STOP SEEING THE ILLUSION!!!" But I can't stop seeing it!
I’ve seen illusions like this before (Brain game), so I knew what was happening. Though it was hard, but I could turn it off here and there.
I saw it for like a second
Wow I get it now😁
yes. there is that one moment where you nail it but then it ends immediately.
@@shilyarrmee Even knowing what's happening, synchronizing sight with the illusion remains difficult and the illusion, persistant! lol... The dancing ballerine and the mario bros spinning coin are fine examples too! The coin spins in both directions simultaneously lol
This is the first optical illusion that I've been entirely unable to see normally, my mind is fooled each time. What the heck.
Same here. I’m finally defeated by an illusion.
same - watch the shadows
Check a far edge, keep an intuitive sense of rotation and understand geometrically what this object is doing, proceed to track that edge visually (follow with your eyes) along it's intended path. The illusion will quickly fall apart and you'll be able to pick apart which edge is nearest to you
I can see it only if I'm on a table that's slanted at 33° (head down), tilted at 11° toward an old black and white CRT screen, moving on a dolly, in a counterclockwise circular fashion around said TV at 2.5 mph, while eating Honey nut Cheerios, at sunset.
@@hanleyk lol
The point you made so well captures something that I've struggled to put into words and show an example of for years, the missing data between what is observed vs what is. Perception being the brain trying to make sense of the input . And how that might skew results , human understanding is riding on a lot of assumptions. Take that into account when you feel too sure. Wisdom is knowing that we know nothing, be humble . I want to incorporate this into a visual art sculpture
The Curiosity Show was fantastic. Thanks Rob & Dean for your incredible work on the show.
makes this attempt look utterly lame
The most incredible thing is that he trust the thin wires holding it up
i know right

Those thin wires are incredibly strong and I doubt he was even stressing them by being up there.
@@sacripudding4586 Many a famous last word was very similar ;)

its just like

@@uni5396. *reverb fart sound effect*
I've watched and rewatched so many times trying to see the rotation, but every time I fall for the illusion.
Usually, you have to kind of play along with an illusion to get the full effect. This is the opposite, it doesn't go away even when what's happening is blatantly impossible; it gets worse instead.
It's also the only illusion that's ever managed to make me feel strong emotions. Specifically frustration and a desire to yell at reality.
Ohhh man you just hit my nostalgia button with The Curiosity Show. It was an after school must watch in the late 80’s/early 90’s
That rotating trapezoid illusion is mind blowing . Although after watching that rotation 10 times , now I could sense that it's rotating and not oscillating but still it's need lot of focus to see rotation
My brain: gets it finally
My eyes 1 sec later: no
Yes, I can see it sporadically and momentarily. Then it’s immediately lost. I think it’s going to turn out to be good concentration practice.
I still can't figure out if it's rotating clockwise or counterclockwise lmao

Starting off this hopefully exciting year with thisexcellent lesson. Thanks a lot.
Well said.
Unfortunately, some people seem to think that this means *all* interpretations of reality are valid. Excuse me? no.
Facts might support multiple interpretations, but that doesn't mean all interpretations of reality are supported by the facts. Lots of people seem to think facts just don't matter.
Another lesson: even though there are many things that are uncertain, there are also many things that are certainly wrong.
This is the culminating speech of the video for a very good reason, such an beautiful way to end it of, it gives the whole lesson meaning.
Ah, Reddit. The literal shithole of the internet.
Your hands on the frame was what finally allowed me to see the reality instead of the illusion
it initially looks like it stops for me, but once I fully understood what was happening with the Rubik's cube it (somewhat) broke the illusion for me as my brain adjusted to what I was actually looking at. Also, interestingly, the Ames room illusion has always been really fickle for me, I only seem to actually get it about a third of the time or so.
The way someone once explained it to me, the reason these types of illusions ultimately work usually has to do with the fact that we actually only have 2D vision, not 3D vision (if we had the latter, we'd be able to see every surface of every object from all angles simultaneously, which is obviously so different from how our vision *actually* works that it's not even really possible to imagine it accurately, but this is how a hypothetical 4D being would presumably see the world), but our brains are really good at combining 2D images from our retinas together to allow us to perceive depth (from a single directional vantage point, at least) and distance in 3D space. Our brains are *so* good at it, in fact, that they'll even do it with actual entirely 2D images like paintings, photos, etc. not to mention moving sequences of 2D images like films or animation. However, this means that our brain can also be somewhat easily "tricked" into perceiving illusionary depth in other situations where it seems to directly contradict other visual information we are receiving (because really, all depth perception is kind of an illusion for us in some sense), like when an object appears to move in a way which doesn't square with the way our brain wants to fit it into 3D space (which is sort of what's going on here).
The reason it varies somewhat is because different people's brains are essentially trained to intuit somewhat differently shaped 3D spaces (like the interior of a rectilinear building versus a rounded building, for instance) depending on what they get used to during the very early formative years of childhood when we're all first learning to understand this space which we can only *directly* perceive a little over 2 dimensions of at most. But even with these differences accounted for, *no one* can actually see in 3D, it's just not possible with the physics of how light moves through three spatial dimensions, and the physiology of how our eyes are able to obtain sensory information from visible light. Obviously, this last part is pretty much me restating what the video already says, but yeah, our limitations due to 2D vision are usually what's ultimately to blame for oddities like this.

Now I'm just an old guy who really likes what you are doing and the philosophical wisdom you incorporate into your musings and teachings. Great fun for any brain!
What is even more trippy is that after forcing myself to think that they are spinning constantly the illusion 'broke' and then I had to try to see them as oscillating.
And then I could switch back and forth at will by just thinking which way I wanted to see it.

Unless I focus and concentrate really hard on the "thinner" end, my brain is totally fooled. And I love it :)
Exactly the same solution I found. If I concentrate completely on the short edge of the trapezoid, and mentally keep track of where is should be going, I can actually see the window rotate.
Same

@@Garrett_Rowland дого3
I don't know if there's a prize or anything, but after one or two tries I was able to see the yrue movement of the Ames rectangle. First with the rubiks cube attached;second with the ruler attached; and finally on its own. I think it helps focusing on one point( in my case the short end) and mapping out its trajectory. So when it's turning around you expect that point to be at a certain place and look for that. And surely your brain sees it at that point as opposed to the illusion. It was really fun exerting my will over my brain. Haha
I have always found it amazing how our brains are programmed even at a subconscious level. In Haunted Houses and Fun Houses, it is not uncommon to come across a room where a stationary bridge goes through a spinning cylindrical hallway. Automatically you will start to feel dizzy and your body will feel almost as if it is flipping over. That is because your brain doesn’t understand the concept of a room flipping over and over so your senses are telling you that you are the one who must be flipping over and over. All fascinating things.
When he was rotating in the window at first, I could only see him rotating and couldn’t figure out what the illusion was. As he explained that it appeared to oscillate, my perception automatically switched to that and now I can’t switch it back 🤯
It is like me listening to the yanny/laurel thing too much and not being able to hear laurel even with pitch shifting.
Same! As soon as he told me it oscillates, that's all I could see from then on
The opposite happened to me XD
that means you got the g.e.y :(
That's the point though - the illusion makes it look like things are rotating 'through' the window so you saw what most people see.
The illusion is enhanced by the camera's single "eye".

I used to have a hard time breaking the illusion, but after years of visual arts training and practice, I'm much better at seeing through illusions in shape, motion and colors.
I am able to see the rotation when I fix the bottom of the image and keep my eyes focus there. As soon as I leave that spot I was looking, the oscillation returns. Pretty amazing stuff!
if you stare at the corner you can actually bypass the illusion sometimes
Yes
I just think of it as a 2d object and I can bypass it
I find it easier if you focus on the imagined vertical axis around which it rotates. I focused on it by coincidence, but since then I could always see through the illusion. Even switch back an forth like is the case with more common illusions.

Fully agreed. Take a substantial amount of a dissociative anaesthetic like ketamine or - even better - dextromethorphan, lay in a dark room, and then come out of it with the same interpretation of reality that you had before. (Ketamine and dextromethorphan can be dangerous. Do not take if you don't know what you're doing.)
Absolutely!
But did you watch The Curiosity Show?
At the very start of the video, when you were talking about the sponsor I was distracted and not paying much attention, so I saw it spinning normally, no illusion. Then eventually I focused on watching the video and only then I started perceiving the illusion, and then the ruler and the cube killed it. I honestly think that if I wasn't searching for that, I might not have been "fooled" by it.
I've found that difference in perception interesting, so I wanted to post it here.

As a human biologist it's so amazing to think how our brains process their environments. We humans have specific neurons (called grid cells) which are active in hexagonal patterns as we move around. We also have specific neurons which tell us when a person is looking at us or somewhere else. And in a quite funny experiment it was also shown that specific neurons are highly active when they hear the voice of Homer Simpson (would love to make a video about that myself). The fact that our brains fall for optical illusions just adds to their awesomeness!

I lost my left eye about 18 months ago and now am attempting to coach my daughters volleyball team. It's super hard for the girls to understand that I am sometimes struggling to see which side of the net the ball has fallen to. Furthermore I had run an industrial repair company for 30 years. After the accident I was only able to effectively repair items that I had previously repaired prior to the accident. Newer items that I had never seen previously all looked like flat nickels. It has been so hard for me to understand the thinking of the engineer without being able to see the depth. This also is so hard to explain. Now after seeing this video, I can see why I'm struggling. Super helpful really!! Great job as always.
I was born crosseyed which we now know must be corrected by age 3. Mine was corrected at age four so I never learned how to perceive 3D space. This is because my mind is unable to merge the two images to resolve distance. I know the size of objects and the size they appear at various distances which is a poor mans 3D. I know it isn't reliable so when I drive, I allow additional stopping distance. Catching balls only happens with luck or a correctly placed throw. On the other hand, I can throw with reasonable accuracy. I think what I do can be learned but I have had a life time doing it. I think to learn what I do, you need to relearn what the world looks like.
The strange part about it is when I work with objects I still can think in 3D. I can rotate them in my mind and see what they look like from another angle. Probably the best advice I can give you is take it slow and easy. You need to relearn what the world looks like and it will be time consuming.
I lost vision in one of my eyes 50 years ago at age 10 and for a couple of weeks I had trouble knocking over water glasses but I think because I was younger I didn't really ever notice a difference and have had great depth perception.
I have read where when we are born most things are blurry because light is reflecting in all directions and it's our other senses such as feeling edges and corners that allows our visual cortex to process the shapes so the next time we see that particular scattering of light we know what shape and object is.
"Oh the Irony" that got me so well

finally i saw it rotate
Yeah, "irony" got me to subscribe.
Brain: “Oscillating”
Veritasium: “Rotating”
Reality: It is just a 2D video, the pixels just get squeezed and unsqueezed over and over again.
You're just sitting in front of a panel presenting a stream of quickly-updating colored dots!
Actually, the pixels remain the same size no matter what they are representing.
@@ericcsuf So the pixel colors are oscillating
Pixels getting squeezed? Dang, my monitor must be really out of date then.
@@jlco Stop living in 2020! Get with 2021! Squeeze pixels are the future! ;)
Wow, the message toppled the contents which is on of the best i have ever seen on youtube
I stared at the upper tip of the longer half of the illusion, it helped me see through it when I paid attention to the illustrations’ creasing.

or maybe compound pulleys...;-)

Now you should make a video on déjà vu.
nice
I could totally ride a bike reverse handed, if I really wanted too :p
This is fascinating and mind boggling. Even knowing what the image looks like, knowing that it's rotating, knowing how the illusion works and why my brain is fooled, I still can't see it any other way. It just seems impossible for my brain to look at it as rotating naturally.
Thats a lack of thought control to the best of my knowledge. If you want to be able to better perceive illusions and such you should play around with some thought experiments
Try staring at the outermost line, you'll see that it rotates!

@@fiecl4383 ?
@@blankblank It's not a conscious process whatsoever. Some people will never be able to perceive it differently because of how their brain computes the stream that the consciousness views.
This my fav video yet. Been binge watching this channel.
This has been my favorite
Illusion for a long time.
Can't get to the rest of the video because I keep replaying the bit at 0:18 over and over again. Such an incredibly bizarre-looking effect! I'm very curious to learn how it works, juust gotta watch it again one more time...
Damn Sebastian lague!!!! I Love your channel
*one more time*
Dang, not all surprised you'd be watching this, your new series on binary circuit logic is really great, thanks and happy new year.
I can finally un see it
I still couldn't see it until he hung himself on it😁
Tittle: The illusion that only some person can see
Alternate tittle: The illusion that a person can only sometimes unsee
are the 2 ts in tittle in this context an illusion?
@@thetreasonseason delete this now.........Not everyone is able to see through an illusion....
I figured out that if I picture the movement its supposed to be making in my head, then suddenly I can make sense of the entire rotation, but only if I focus.
@@dalmaronthefirst2237 Same, but there is a moment where my brain goes "wait wait wait, I had blinked and missed averything!".
@@EnabiSeira yeh and then I have to start picturing it all over again. Its REALLY hard to do through an entire rotation.
Man all those click bait channels... yet here this guy goes to such lengths for his viewers.

right
Yep
That slight bending helped me see the complete rotation.
This is a really great and educational video and I love it so much. I'm going to show this video in my class for my students and, hopefully, they will be enlightened with a new and positive view on Science and perceive the world with a new and creative view.
After watching this and trying as hard as I could, I eventually was able to "correct" the illusion if I concentrated and told my self it's moving toward and away, instead of taking in the whole picture.
I could do this for just a second, but only because the card had a slight bend to it
i was really confused until around 6mins, then i saw it. it still flickers back to the illusion every now and then tho
dude idk what the heck is happening I'm not smart enough to correct it
@@mama_caca same, it's driving me crazy
@@helen4278 its actually easy to see, try to lock on one side, and after half turn you see that it is oscillating, but in reality that side coming away from you is coming towards you, you just need to convince your brain and then you will see it
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..
Only when he was jumping through because he was braced with his hands in other frames and it offers a reference but yeah it was driving me nuts also.
That's good, people who can see through this illusion are at higher risk of schizophrenia and derealization.
@@saigonpunkid do you have evidence to support that?
I was able to tell by looking at the corner of the small side. It's a little cheaty tho cause its curved a bit
haha
Love the video. The end was brilliant!! 💖
The proportions of the smaller and larger side seem to be important. I understand how the illusion works, and I can see it rotating for a moment! It’s like the illusion breaks. But mostly it oscillates.
My Frontal Lobe: "This is quite interesting. Neat."
My Basal Ganglia: "What sorcery is this? Kill it!"
Which tells me someone should include such an illusion in a haunted house. Put someone inside the illusion and paint it to look like big scary blades.
AAHH! NOOO! IT'S KILLING ME!

1:11 I grew up in Switzerland and got to enjoy the Curiosity Show dubbed in German as a child. I'm in my 40 nows and it took me a long time to figure out the name of the show just from random details I remembered. Eventually I did figure it out and watched a lot of it on here just a few years ago. So to see that show mentioned here is very special to me because I loved it as a child and I still love it now 💙
I managed break the illusion. You have to stare at the top right corner and focus only on the white color and not the blue one. What creates the illusion are the colors, not only the shape.
Focus on the white color, and stare at the top right corner. Then, halfway into the rotation, you'll start to see the back of the top right corner, which now will be on the other side once it "flips". The top right corner becomes the top left back of the corner.
This is the best example of when u can't unsee
idk. I can kinda decide if I want to see the Illusion or not by focusing on different points
I've tried it, but it's still hard
"These days a lot of people are getting basically the same, fundamental information but coming to very different conclusions about the state of reality."
Truer words have not been spoken.
the problem is people who tend to say this really mean "why aren't you seeing the world the way I do" instead of "I will consider seeing things from another perspective" or "maybe we have different solutions but your not evil for disagreeing with me or activley denying there is an issue"

Derek's final comment -- about having humility in areas outside the world of science -- reminded me of the episode "Knowledge or Certainty" from Jacob Bronowski's masterful series "The Ascent of Man." Bronowski criticized those who believe that they had "absolute truth," a priori -- and that that certainty can lead people to commit atrocities because of their belief that they already have everything figured out.
This was my biggest confusion since last week, when i observed this phenomena in park's gate... Thanks for this explanation 😊

Kudos for mentioning the "Curiosity Show". Rob and Dean were my heroes too.
I've appreciated this illusion for may years, and this is the best presentation I've encountered!
That said, I was a bit blown away by the dual window experiment with babies.
Having recently (~10 years - I'm old!) lost all vision in one eye, I very clearly see BOTH windows oscillating.
