Not in the video but Time. The rate of which we observe energy move matter through space in some shape or form. The faster rate we observe reality the slower time progresses and obviously the slower we observe reality the faster time progresses. This illusion can make a day progress faster or slower and our other senses help influence this like fast or slow music. Even if we were to travel around the speed of light, time may appear to stop but in reality we are still travelling at the speed of light. This illusion is so good its even fooled scientists to think its a universal constant when in reality its an observer constant, because you cant have time without energy moving matter through space in some shape or form. (Even our senses are based on energy moving matter through space in some shape or form and without it we can't observe time!)

It is, and there have been several car accidents of autonomous vehicles caused by AI suffering from those optical illusion. Also, the AI is really stupid still (do not let anyone try to tell you it is smart). It is trained to see certain shapes, but it uses really weird probabilistic method to get there and it can be fooled quite easily into "hallucinating" you can have "almost" random noise images that AI (specific AI, mind you) will see letters, numbers, and even images). And there is almost invisible makeup that fools a lot of intelligent cameras that will not detect your face properly. (Optical) illusions for AI are quite a fun topic.

Thank you, thank you. This has finally given me a coherent explanation for something I've experienced my whole life. Long story: when I was born, the doctor had to use forceps and clipped a muscle in my right eye. The resulting amblyopia was so severe they had to patch my left eye for the right eye to even develop. I was always looking through both eyes, but the eyes learned to move independent of each other if one was covered. Optometrists tell me this is not normal, but a coping mechanism my brain developed. However, the left eye remained very dominant until I lost most of the very central vision in the left eye to histoplasmosis at age 26. Only then did they discover I had pinprick scars all over both retinas, and that I had actually had histo since childhood. Not only did I have to teach the right eye to read, I had true binocular vision for the first time in my life. As a result of all this, most optical illusions have never been visible to me, including the Ames illusions. Looking at such things always gave me a headache which has always been a signal that something wasn't right in my worldview. Thank you.

I’ve seen this subject done by some of the more physics oriented channels (e.g. Veritasium and Vsauce) before, but I liked getting Joe’s perspective on it. He definitely approaches it from a different angle. That being the biological factors which lead to one’s perception of illusions, rather than just the “coolness” and math. I used to think the fact that I couldn’t see illusions was another aspect of my mental disability (autism), but now I’m wondering if it means that my perception is better than normal? Maybe a trade off; better perception of reality at the cost of being able to relate to people. I compensate for my autism pretty well through memorization and understanding the things I don’t inherently perceive, so maybe it’s not actually a bad thing over all.

I wouldn't say it's better or strictly worse (obviously it kinda sucks to not be able to recognize emotions easily), just different. That's how i view most neurodivergence. The way it seems to me is that autism turns off a lot of image recognition stuff in the brain, so you're seeing a more raw, unfiltered view of the world, so to say. IIRC people with autism often describe that they see component parts of stuff they look at, rather than identifying them as a whole, is that correct? Like a face is two eyes, eyebrows, a nose, and a mouth, whereas a neurotypical person like me just sees a face as a whole, and it takes some concentration to look at each part separately.

I'm a little surprised shadows weren't mentioned. Two objects of the same size, seemingly at the same 'height', can be mentally positioned either next to each other or along a diagonal line away from you based on whether their shadows are right underneath them or one of the objects appears to be 'floating' away from its shadow. And that's just for two objects that don't have shadows overlapping each other or other objects you can see in an open space. Shaded objects also do a ton to help you figure out distances, positions and sizes.

I'm not a historian, but a loooot of art back then was in pottery and shaped objects. What use for perspective would they have in those mediums? It's no coincidence to me that perspective paintings became common when... well when paintings on flat surfaces involving geometric architecture became common?

One of my favourite famous optical illusions in MC Escher's Endless Staircase. It works no matter what angle you look at it and whether you look at it with one or both eyes, because it plays with how the brain processes 2D images to try and create a 3D world. But since some images, like the endless staircase, are physically impossible in 3 dimensions, it makes the brain got "WTF?!"

The Ames Room illusion actually can still work with two eyes; I've been to a couple full sized ones, and with the right lighting and with the surfaces kept clean, you might still get the impression people on each corner are somehow the wrong size or change size as they walk across. The effect does break down if you move too much or if you're too close to the walls and stuff though.

as a software engineer makes me wonder how effectively these perspective hints can be quantified and incorporated into something like the software that parses image files generated from a camera for image based AI, being able to cull large amounts of data based on these hints might be an effective way to reduce the number of objects the AI has to interpret, assuming the implementation of the culler didn't prevent the AI from hitting its hard real-time requirements, obviously there has to be some set of existing object culling algorithms in image based AI already, wonder if any directly use techniques like this, I would assume they'd have to be relatively simply and thus efficient based on the fact that they're 'cognitively impenetrable,' but then again maybe that's like saying, 'because I can't choose to see something as green instead of red it then must be easy to distinguish color' -- anyway...

Machine Learning for images mostly use CNN (convolutional neural networks) but they could also use just a dense NN. The training time on a dense neural network for images is insane though especially when considering lots of images. That being said in a way they are being trained on these "rules" of reality in a sense as we feed them images with perspective typically. Something else interesting is you can have separate hidden layers learning features of a specific subject. For example, a dog can be broken down into limbs, ears, face, and etc that way if you just see ears in an image and nothing else it can still classify them as dog or not dog. In this way the model is constructing an object in reality from more ambiguous sub parts. It's really cool stuff you can even use this approach with a GAN which was displayed by NVidia recently to do image editing, transformation, or just creating whole new objects from what it learned and constructing the image out of its sub parts.

This was great, because it isn't just "look at these cool illusions, lets figure out how they work"! It's funny to see how unreliable our ability to perceive things is, and maybe would've been worth mentioning not only does our perception rely on educated guesses, it's also always behind reality, so we technically cannot live in the now in terms of our senses. I think the distance illusion with the two dots or circles suffers a little from the camera focus, because you can tell the right side is closer by just looking at how detailed the surface is. Granted that's much easier to do afterwards when you know what it's about. The Ames' window is still really funky to look at, even after seeing this and the Veritasium video on it, it seems unreal that it's persistent and takes quite a bit of effort to override the automatic error correction to actually see the motion as it truly is. Fascinating stuff!

The Ames window is not cognitively impenetrable. There is a subtle clue, that once identified, breaks the pattern. Now, most Ames windows have a characteristic curve, due to the nature of their construction which gives it away, but even in a perfectly constructed Ames window, the "far" end changes size dramatically compared to the "near" end. Once that feature is identified, it is exceedingly difficult to shift back into the illusory frame. The Ames room is perfect due to the stationary state of the illusion generating space. But the moment you add true motion to an illusion based on depth perception, several nuances of motion perception add new features the can break the illusion.

Object permanence plays a role in vision and can be messed with too... this is common with magician's trick that involve objects that: spontaneously appear, disappear, and/or reappear... the parallax effect works because you understand object permanence. All your visual understanding of motion is tied to your understanding of object permanence. Object permanence is way more nuanced then parenting books would have you realize. You expect some things to move, while you expect the location of other things to be more permanent. Object permanence isn't just realizing that objects don't just spontaneously disappear... it's also realizing that certain objects do disappear... you don't expect the flame on the end of a match to still be there 10 minutes later... unless the match is ... wait for it... really really long... see what I did there? You knew the exception before you read it... you understand the conditions surrounding and affecting the object in question. You know that Play-Doh doesn't have a specific shape and it's shape is subject to change. There are so many subtle nuances to your understanding of object permanence. Basically there a spectrum of how permanent different aspects of the object are... shape permanence, location permanence, distance permanence (something could go back and forth on a curved track... moving but maintaining the same distance from you ... thus distance permanence and location permanence are not the same) color permanence, the list goes on, the point is these concepts exist on a spectrum some things stay the same color, some things chang to all different kinds of colors and some things only change color within limitations be it a limit to the colors it can change or it being a limit to how long it can be a different color than usual or like rabbits maybe it stays a color for a whole season but what color is the rabbit? It could be any number of colors but it's not floracing a neon blue... that's a given, until.... the context says that the rabbit was seen on a sign in a bar window... then that color option doesn't seem so ridiculous all of the sudden. So there's lots of subtlety in this aspect of vision. AI vision for self driving cars, knows about the hot summer road mirage effect, where it looks like there's a puddle way ahead of you in the road, but when you get to it there's nothing... yeah we're getting to that level of sophistication when it comes to teaching ai vision about the subtle nuances of object permanence. So not only does it know that stop signs don't move but cyclists do, it also knows not to engage traction control for a puddle that doesn't exist... Anyways I babbled on long enough... I just wanted to bring the concept of object permanence to the conversation.

a cool illusion I like, is to look at the Arc of the milky way, then tilting your head to the side and realizing it's a straight line. also works on sunsets for those that don't have a clear view of the night sky

0:08 - That looks normal to me because it's flat and not square. I see it spinning in one way! I can't see the illusion. How 6:43 - Not mind-blowing to me. Bruh!

Exactly the same thing happens with our hearing as well. In music, if you just hear a C major chord, you assume it’s a piece in C Major. but depending on the context of the music following it, the piece might actually be in G Major, or F major. This is common knowledge, among musicians and composers. It has been used for hundreds of years to fool the listener, which makes the music more interesting! You could do a whole program on how our ears fool us as well.

Multiple sclerosis started warping my senses and it got worse after the disease progressed. Psychadelic therapy has completely changed my primary visual cortex. Not only can I see better, my eyes interpret everything at a much higher level as well. Therapy permanently changed my vision. I prefer this to being blind

Indeed your channel is one of the best educational channel in the world. I have watched all your videos and I love them. In fact I started watching your videos when I was 12years old through TV channels. Those times I did not know English but I used to watche them in persian. Lots of love and respect

The Connectivity illusion hits me the hardest as someone who frequently creates 3D assets. You almost have to keep your attention split between multiple point of views to avoid creating these illusions on accident. Depth perception is the one thing I was excited to gain from in 3D monitors, but that market went bust.

Not enough attention is given to the focus of our eye's individual lenses. it's an issue especially when it comes to VR headsets. it frustrates me because it never gets mentioned but it can be a real contributor to eye strain and headaches.

When you mention the two eye trick, I have that, but most of the time my brain doesn’t know which one to use do I always see both. It does this because I have an astigmatism in my left eye. It learned to ignore it. WoW. But now my brain has to learn it that it is getting correction from my glasses.

Often seeing visual illusions causes a weird tingly feeling in my head... Some of that stuff and a somewhat popular game called 'Fez' (where you create 2D planes out of a 3D world by changing perspective) are just... wrong. That rotating window that doesn't seem to rotate is especially tingly :D Even more so when you placed the slip into it... yurgh.

I've never had binocular vision(right retina detached in infancy), and while I knew there were some optical illusions that depended on binocular vision(such as staring at your hand with one eye and looking through a cardboard tube with the other forming an image of a hole through your hand), I never knew there were illusions that binocular vision destroys. Sadly, thanks to my left retina detaching in my mid-20s, I couldn't get the full impact of the illusions in this video, most of which I've never heard of before... Shame there isn't more content out there on non-optical illusions... Theres some on auditory illusions(Shepard Tones are probably the most famous where combining ascending and descending scales in the right way gives the illusion of an ever increasing pitch when its just the same octave over and over and there's a similar illusion for tempo), but the only illusion I've ever encountered for the other senses is one where gripping a heated bar in one hand, a cooled bar in the other, and then switching to an ambient temperature bar after about 30 seconds makes the ambient bar feel warm to the hand that gripped the cold bar and cool to the hand that gripped the hot bar. Granted, audiovisual illusions are the only ones you can actually demonstrate properly via video, but still, I doubt the other senses are any harder to trick than the eyes and ears. And in response to a comment about AI vision further down... I won't pretend to understand how computer vision works, but I think it worth noting that you can theoretically build a computer vision system with a whole bunch of camera modules, each getting a different view of the same scene, effectively emulating the compound eyes of insects... and that said camera modules can be made to detect infrared(I understand most digital cameras are sensitive to IR, and have a filter that only lets visible light through the optical part of the camera) and ultraviolet and use tricks for determining distance not available to human eyes(such as scanning aa lower power IR laser over the sene and using the round trip time to determine distance) or combine visual information with things humans don't have the right senses for... Software making sense of the raw data in a reasonable amount of time is the hard part, but in some ways, the computer's senses could far outstrip human senses.

15:43 "One of the strange things about most of Ames' illusions is most of them only work with one eye from a very specific spot, which is why so many of them work so well in video". But there's one rotation illusion you can see with both eyes in 3d reality from a locus of positions. A two bladed wind turbine when seen off to one side will appear to rotate jerkily, but smoothly when viewed head on. The best explanation I can think of is that the circle traced out by the blade tips will foreshorten (or perhaps "forenarrow") to an ellipse when viewed from an angle. The tip of a blade has less apparent distance to cover when approaching and leaving the vertex (pointy end) of the ellipse and will thus appear to slow down to compensate, and correspondingly speed up when passing through the co-vertex (flatter bit at the side). KZitem has some examples of two-bladers, but go visit in person if there are any near you.
@chrisg3030

So what's the brain doing here? Does it deliberately slow down the blade tips in order to keep phase with them?

I experienced a traumatic brain injury in 2017, losing my identity, about 10 years of my life, certain language abilities, and, interestingly, a shift in my visual processing of illusions. Rather than seeing one illusion or the other, i now see all permutations/angles simultaneously. IDK if it's exactly related, but post-TBI I also gained math and science skills i hadn't had before--like I now see/think in geometric pictures rather than linear constructs. I keep wishing a neuroscientist would take me on as a guinea pig to explain more about it.
