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
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.
I think lighting has a big part to do with it. It was difficult to see at first but then at 3:52 I saw through the illusion.
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
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

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.
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?
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
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

I got it the first time, but now I cant get it
I was able to beat it after a little bit of focus.

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.
@@TN-br9yl So basically knowledge shapes experience it seems... This is profound.
sorry pal i knew it was 2d really fast :') between the camera angle and the light reflection it jsut gave it away
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
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.
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.

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.
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.
That hands down is the craziest illusion I've ever seen.

@@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.
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
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
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

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.

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!
The Curiosity Show was fantastic. Thanks Rob & Dean for your incredible work on the show.
makes this attempt look utterly lame
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
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
@@TIO540S1 -is Kool.
i think somethings wrong with me cus i saw it imediatley
My brain: Visualises it turning around
My 1st eye: no
My 2nd eye: yes
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 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.
The ruler part is so weird, it phases through the window but in such a weird way, like it’s not actually clipping through, *this is so wild and infuriating at the same time*

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.
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.

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!
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.
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.
Life lesson:
"My brain prefers the illusion over what is really happening"

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.

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.
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
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.
HOW ARE YOU IN THE COMMENTS OF EVERY VIDEO I WATCH
yeah
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.

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.

One more blurry peek into how our brains work...
6:28 - focus on the pointish section end and watch it go round, if you stare hard enough you can see it rotate round fully, keep ur eye on that point and keep in mind it is going in a circle not back on itself so view it like that is definitely what's happening (worked for me anyway) its anticlockwise
12:10, focus on the longer side and watch it go round fully, keeping ur eye on that one spot and keep an open mind of ah yes it is continuously spinning clockwise

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.)

Once I saw it correctly, I couldn't unsee it. Sometimes my brain would flip back and fort between it tricking me and not. Now i'm even more confused. This is fascinating.
The perceptual inconsistency is what I find cool too lol.
Had the same issue here too. First time I saw the rubix cube scene I saw it correctly and had a hard time seeing the illusion, but then it would flip back and forth. Now I can /somewhat/ choose which way I see it, but it's still wacky and cool.
@@bentracy7463 *Rubik's
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.
I really love it. I spent half an hour for 16 min video i slowed my speed and concentrate on only cube then i realize its really rotating. Ames must have worked hard to invent this

Well, I still remember that in my childhood there used to be a painting of Monalisa at my home which my grandfather had bought a long time back when I was born. I used to see that painting and when I look at her eyes I used to feel as if can continue following the direction of my movement wherever I move around. If I go on far right it starts following a weird stare at me or the same on the left side as well. I think this is what this illusion is meant about.
My Frontal Lobe: "This is quite interesting. Neat."

Yep
Wow, the message toppled the contents which is on of the best i have ever seen on youtube
Love the video. The end was brilliant!! 💖
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!

Excuse me what? Homer?
Also nice to see you here
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.
I selectively choose whether I see the illusion or what's real. If I concentrate on the trick I see it for what it is, but if I just lazily look in its direction I see the illusion. This works most of the time, but early on flickers back and forth which can be disconcerting. Fortunately the longer I focus, the easier it becomes to keep straight.
I was able to see it when I carefully watched the rubric part but wow I had to keep telling myself the small side was in front. The forced perspective from the relative sizes of the long and short sides makes it really tough. Very cool to watch as an illusion with the attached items appearing to move differently from the substrate
I saw the rotation correctly and now I can not unsee it to be fascinated.
it's fascinating and it's even more interesting cos i can both watch what's actually happening and the illusion itself by choice.
Same you can see an optional illusion but you can't unsee it
It’s because we are Asian

I saw the illusion, then by the end of the video i only saw it rotate.

@@pratn god this got me cracking up...
finally i saw it rotate
Yeah, "irony" got me to subscribe.
This my fav video yet. Been binge watching this channel.
This was my biggest confusion since last week, when i observed this phenomena in park's gate... Thanks for this explanation 😊
It's so cool how you can condition yourself to see it in different ways.
Yeah, it reminds me of those Laurel and Green Needle audio clips
It’s like the drawing where you can either see a duck or a horse. Some writer said that, that was real magic. A person might only see a horse until they’re told that there is also a duck in the image and once told how to notice/see the duck, the duck drawing “magically” appears in ones mind/perception.
"Stop being so certain about things" Should be the automated response when anyone posts on twitter.
""Haha your opinion sucks mine is the only valid one so shut up""

are you certain that we shouldn't be so certain?? 🤔
@@zeffery101 Certainly.
It's wild. At the start of this video I couldn't unsee the illusion no matter how hard I tried, but by about six minutes in I started seeing it rotating. Then the "circle" immediately got me...
I was having a hard time seeing the rotation there for a minute, but I found that when I just focused on the top corner of the larger portion of the window it became very clear
"This doesn't make any sense"
*Proceeds to make sense of it*
what ?? Noooo it makes sense !
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
That's so cool. Even with the cube, the illusion holds.
What allows you to break it is the slight curve at the top. Allows you to see which side is in the front.
But some times, I can just see it rotating. Which is weird to me.
Neat thing is that on the circular illusion I can force myself to see the rotation and switch back and forth. But with the rectangular one, no matter how hard I try I cannot fix it to rotation vs oscillation.
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 am trying to convince my brain everytime that it is rotating not oscillating, and at the end of video, my brain says, ok then I'll rotate everything for ya. Dizzy😵💫
If you looks at the bottom corner of the long side, you see it rotate a little bit more imo.
Your brain will always trust your eyes above all, and that is especially exemplified by the McGurk effect.
I saw it oscillating, however I do understand how people see it rotating. Looking at how it moves when it ‘slows down’, It seems as if the long side is coming back however it really does use things like how far away things are which is why I understand the roatation look.
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.
When I looked at it long enough, eventually at the point where it "reverses" oscillation I could start seeing that it doesn't. Concentrating on it, this moment extended to almost the full revolution. The illusion was broken for like, the whole day. Next day, it was there again, and I had the same trouble forcing me to see it differently... weird... almost like this red and green pattern that changes your brainwaves for months...
The funny thing is that even if you see through the illusion you see the window "slowing down" thought it's spinning at a constant speed
I found the rounded window significantly reduced the illusion for both windows for me.
I dont understand what illusion people are seeing? I dont see it, just him hanging there and spinning.
"red and green pattern that changes your brainwaves" Where is this illusion, what's its name?
its in the modulated waves of cellular technology man. Theres no hiding from them now. they gotcha man.... they gotyou
Kudos for mentioning the "Curiosity Show". Rob and Dean were my heroes too.
its a great illusion for sure. i really wish you could have a continuous shot of it rotating, then moving the camera to a different angle to see whats really going on.
When the trapezoid actually comes to view I perceive the smaller edge is somewhere in the back... with respect to the camera and the longer edge... and then it looks like it is oscillating. It took me all the energy at first to see the rotation but then I realized and told myself that when the trapezoid is seen in its full length, it is actually horizontal to my view and that is where the rotation begins... I started to clearly see the rotation.

Wow great video! 16 minutes quickly became 20 because of how often I was watching certain parts multiple times.
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.
