You can never see your eyes without them looking at themselves. Try looking away then look back at your eyes seems like your mirrored self's eyes don't ever move, like he's constantly staring at you. Food for thought
"The mirror did not flip anything, it´s YOU that turned the image" Maaan, I´m a 45 year old, well educated men who is not fallen on his head very often, but you just blow my mind. Holy crap.
@@Chris971. Aye, thanks! I know `Ißm doing horrible things with english grammar from time to time. That´s the downside of missing native speaking sparring partners. Thanks for your hint, hope I remember it next time :-)
Tbh with you, it's just you who thinks you're uglier on the non reversing mirror. If you make people compare which you looks better, the non-reversing or the natural mirror. Almost everyone will pick the non-reversing one because it's what's everyone used to seeing. The reason why you think you look better on the natural mirror is because it's the one you're used to seeing. I hope this helps ❤️
@@pikameme3322 yeah, like in this video for example we are already used to the action lab non flipped so in the actual mirror he looks wierd as compared to the true mirror
Other people DO NOT notice the asymmetry that you notice in a photo or true mirror. It only sticks out, because you are so used to your face as you know it in a mirror. So for all practical purposes you actually look the same to other people as you see yourself in a regular mirror, - the image is just flipped.
You can see the “True image” of yourself simply by getting someone to take a picture of you with the back camera of your phone... while you can see the “Mirrored image” of yourself just by taking a selfie (front camera). Edit: So apparently (at least on iphones) when you do take the Selfie it actually reverse flips the image for you into a “True image” so in conclusion, you can see the “Mirrored image” of yourself just by having the selfie option on your phone and looking at yourself just as if it was a regular pocket mirror. And then you can see the “True image” of yourself if you do take the picture. Edit 2: Also you can capture the image of “the Mirrored you” by screenshotting a Selfie instead of taking the actual picture. And after that you can also take the picture normally and compare the two images in your gallery.
He looks good in the non-reversing mirror tbh. But for sure he thinks he looks better on the other mirror which is just sad. Why can't everyone just use the non-reversing mirror?
"The mirror did not flip anything, it´s YOU that turned the image" A moment of teaching genius. I used to find the concept of mirrors 'reversing' a little perplexing but those words, and that beautiful demonstration, brought instant realization of exactly what was happening.
@@scottlong6176 I know if I look in two mirrors, (like those three way mirrors in big dressing rooms that you can angle certain ways ) If I use those I can look at the mirror image of the mirror and see me how a camera sees me. I still didnt' FLIP anything. Either way I'm just standing there.
@@recoveringsoul755 I find this difficult to conceptualize as well.. But I guess what you have to do is to imagine your face on a vertical plane (in which your eyes just happen to be). Now imagine your eyes behind that plane, just like they are behind the (unflipped) sheet of paper.
To see things you look at them with your eyes. So if you want to see yourself without a mirror, you'd have to rip out your eyes and point them towards yourself. That would have to be the default direction your eyes would have to be pointed at, i.e. yourself. If you look at a mirror instead, then it's like flipping your eyes from that previously mentioned position back into the direction you're facing. -> That's the flip you "did" when looking at a mirror. You basically walk through life with constantly flipped eyes when it comes to looking at yourself in the mirror.
When I saw how people saw me. I died inside a little, my eyes aren't the same alignment, my lips are going to one side more than the other, my face looks more lobsided then one side.
@@tobiasvdb351 well, I noticed that my mandible was crooked for one side, and that was making my whole face crook too. So after noticing 'am making a conscious effort to correct it and that is making my face more symmetrical also.
I've seen this at my local science museum. It could rotate. When I rotated it upside down the reflection became upside down and I was like, "ok, BORING" until I realised that's NOT what a mirror should do.
yeah, its cool when you see it, esp with the perfect optics. there's one at the Museum of Illusions in NY - the Anti-Gravity True Mirror! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eBv3rOjkKoI.html
You should also consider that seeing your own appearance from the perspective of others truly doubles the effects of your asymmetry (to you). If you have become accustomed to the 5° clockwise rotation of your nose, and see a 5° counterclockwise rotation of your nose, you perceive yourself to have 10° of crookedness in your nose! In a sense you have zeroed out your mental measurement to set 0° at the nose you’re used to seeing, shocking you when you see the reverse.
Yeah i was thinking that to myself as well, like, he edits his own video's right?? But yeah, that's not the same as looking at yourself in realtime like he explained.
@@AllenBaby7 Yeah, it's often configurable ... and it really depends on *your* expectations -- whichever one you're used to, if you use the other one, it's super confusing to see 'the wrong side' move.
I've always done this at my grandmas' house where there are two shelf doors that are mirrors and when you open one of them the mirrors are at an angle to eachother and so you will see a mirrored image of a mirrored image of yourself 😜
I really enjoy your videos. Your demonstrations remind me of the ones my father used to perform to teach me Science and show me how things worked. He passed away on January 2021 from Covid and now I am glad to somehow find him in your videos. Keep it going.
For the record, not all Americans say it the way he does. The way I say it sounds more like MEAR-er, where er is basically a held out American R sound. It sounds like mere her, without the h sound. I also know some Americans who say MEAR-rurr. And a few who want to be posh but still have the American R say MEAR-roar. (I would transcribe nonrhotic accents as pronouncing it MEE-raw, MEE-rah, or MEE-ruh, depending on the accent.)
6:06 That laser is not eye safe and is much more dangerous than rated online. Just felt worth mentioning, stay safe around those and wear eye protection! (and not the one that came with the laser)
he was wearing eye protection, at least a pair of glasses is visible in the next scene laying on the table. i think it's safe to assume that he did use them rather than just putting them there but i feel like he should indeed put a disclaimer there or some psa for the viewers who may wanna play with lasers and mirrors. even if they knew that they shouldn't aim lasers at the eyes, they may not realize that due to the reflection's nature, they may accidentally aim the reflection at their own eyes and damage their sight.
@@keshawnmcgee334 ye that's totally what can happen, and he uploaded it to screw everyone's sight. Luckily you've managed to outsmart him and not fall into his trap
Congrats, the first video I have seen that actually explains this properly. If you turn to face the mirror by doing a handstand instead of turning normally, the mirror will appear to flip you upside down instead of left and right.
Atharva if only beautiful people get married the population in this world is not 7.7 billion but less than 1 billion so relax man ,,, what this guys saying is not true ,,,, the mirror flipped the words but not the face ,,,we are like in normal mirror do an experiment take a friend and see how he look in mirror 🪞 and how looks in real life and it's the same ,,, of course in photo we change because depend of lighting angles of camera photo ,,, the human eye are 573 megapixel and the photo are 12 megapixel so relax ,,, what this guy sayd is only supposed
@@preciousthing101 They point is, if you like your mirror image but not your 'camera appearance', it's probably the opposite for other people. They're used to your camera appearance and would probably think you looked weird and less appealing if they saw your mirror image.
I just realized that the front camera of my phone show me a mirror image in real time but, when I take a picture the picture is flipped to show me how do I look normally to other people
This is the first time, I think some one clearly explained how a mirror works on the RU-vid. I have seen other videos on why mirror flips words, but those did not make sense. Thanks a lot, Man!
It- its not 3 mirrors in there... Did u not listen to his explanation of how it works in the end? It's simply 2 mirrors at 45° of each other. So basically a max of a 3 person conference with yourself if u want😄
No, 4-person was right. Through the two mirrors, you can see three mirror images of the world: the one directly across from you, which is flipped twice and therefore looks unflipped, and one on each of the right and the left, each of which is flipped only once. By the way, the angle between the mirrors is 90°. A 45° angle would actually allow an 8-person conference. :) Basically, as many copies are shown as are needed to fill the apparent space behind the mirrors. Decreasing the angle more and more eventually makes the mirrors parallel, which (theoretically) produces infinitely many mirror images, even though there are still only two mirrors.
So true what you mentioned about noticing asymmetries in our faces. I was 30 before I realized (probably when we first got a video camera) that I have an obviously crooked nose, but I'd literally had NO CLUE it was like that. It took years to get used to this adjustment of self-concept. And today, I just don't care. :) Awesome video!
Why hadn't I seen this earlier!!😩😩 action lab i freaking want to HUG YOU RN. This was the video I've been looking for pretty much a quarter of my entire life 🙃
If you point a "true" mirror another "true" mirror and stand in between them, does it create the same "infinity reflection" effect that a set of traditional mirrors would?
I noticed this effect for the first time in the 9th grade. I had a couple of optical prisms from a broken pair of binoculars. They were so perfectly made that placing them together they would stick to each other pretty tightly. Pulling them apart from each other you could feel the effect of suction between two flat surfaces. Holding one prism with the right angle end pointing away from my eye, and looking into the prism, I could see my own eye. I though this was strange, as I expected to see the 'top end' of the prism. Instead I was treated with the reflection of a reflection, which was just so cool.
2:06, fun fact: every good drawing software has an option to flip the canvas cause in the process of the drawing u might get used to ur own mistakes so when u flip the canvas u can spot the mistakes more easily e.g. when sth is unbalanced or so
The first time I experienced this was in a bar. There was a horizontal line of small mirrors zig-zagging across the shelving unit behind the bar. I noticed that the bits of me that I could see moving were not as usual but were as someone else would see, looking at me. For a true effect the mirrors should have a reflective front surface otherwise the glass thickness gives a line down the centre. I've often wondered why some enterprising person (not me) hasn’t produced a hinged pair that could be, for example, fitted on the inside of a fully opening wardrobe door. Then when getting ready to go out you could see yourself as others will see you. I've also noticed that hardly anyone has a triple mirror set these days. They were often incorporated into older dressing tables and you could see even the back of you head. Nearly forgot to say but the first time I used the rear camera on my ipad mini to take a selfie it was disconcerting as you saw a mirror image but the finished photo was as a normal camera would take it. So if you want a reflected image like a normal mirror, just use the rear camera on you phone or whatever.
Really freaking cool man! You also have probably the best explanation of the mirror flip out of anyone. I had a feeling the true mirror was somehow working with a 45 degree angled mirror, but I didn't guess this design. Very interesting thanks!
I always found that an easier way for me to understand how a mirror works is this: a mirror does not flip either horizontally nor vertically. It flips the 3rd dimension: the depth when understanding mirrors like this, what the true mirror does is not really that it does 2 flips that have an angle and those 2 flips are transformed as rotation of twice the angle. because they are at a 90 angle the result is a 180 rotation, essentially it's a U-Turn for light
Because when u speak u don't only hear your self through the air but also through the bones and muscles. Those amplifies and deepens the voice. Try doing a bee "humming".m and record your voice. You will notice the deep hmm vs sweaks.
@@stefannewels1823 No. However, this is a common misconception spread online, mainly by Anti-Neo-Narcissist groups. To disprove the spurious "Only in the mirror" claim, all one need do is to quickly examine the sound wave of the echo of one's own voice before it reaches you for the first time. You might be surprised at what you hear! Or you may not. * Trivia - True-mirrors actually do invert the echo of what you think you hear but the ears flip it before it reaches the brain. That's why we have two ears.
@@Theelectroarcheologist no, it doesn't depend on the angle of the light. Mirrors simply flip back with forward, keeping left/right and up/down unchanged.
BEsT SCIENCE CHANNEL EVER.... I love his live experiments rather than only speaking and defining like other science channels, as well as his way of demonstration. And also his acting😎👌
Note also, the laser reflection always stays parallel to the source beam and comes back towards you. This is why corners are problematic in acoustics, the refction always returns to the source.
Fun fact: we never get to see our own face ever with our own eyes directly, in order to see your face you need something to produce a reflection of it.
"Mirrors don't flip images, but they reflect light." "Because of the double reflection, it reverses the initial flip the first mirror caused." *Visible confusion*
This just makes me in awe of our brains, our eyes flip the images we see upside down and our brains flip the image so we can go about our daily lives without falling down every 2 minutes...amazing nature
Being a magicalholic. I almost immediately noticed the 45" mirrors just from how you chose the camera position and angle at the beginning of the video. I feel so proud of myself now.
Ok, so when i stand on the left, the refection of me will stand on the right, which means he can't stop me anymore, allow me to enter the Refection Dimension
The arrow is, in fact, "flipped" in the same way as the words on the paper. The mirror isn't reflecting the image we were looking at, but the image facing the mirror. The arrow used is a 2d object of which the front and back planes are identical, yet opposite. If you're pointing the arrow to the right, the back of the arrow from your perspective, you are pointing the front of the arrow to the left of the mirror's perspective. Therefore, the fact that the arrow's direction appears to be the same from both perspectives is a clear demonstration that it's flipped. If the paper with the words on it was equivalent to the arrow, the words would be written normally on one side with a flipped "mirror image" on the other. A paper like that would show the same effect in the mirror as was demonstrated with the arrow.
Good video! I teach physics. A mirror actually reverses toward and away (not left and right, or up and down). In the x-y-z coordinate system, the z-axis is flipped. Point your finger toward a mirror, and the image points its finger back at you. The true mirror has a double reflection, which cancels the apparent left-right reversal. Plane mirrors produce virtual images. They appear to come from behind the mirror, but can't appear on a screen there (as no light actually comes from them). You can still photograph a virtual image. Images at the movie theater (produced by a biconvex lens) are real as they are on a screen. Physics is PHUN!
When you face your back to the mirror and someone else sees it, if you close your right eye, in the mirror it will also look like you closed your right eye. So yeah you are the one that is flipped
Not all camera lenses are created equal either though. Lenses can warp our features and angles and physical appearance. So sometimes we don’t like certain photos depending on what lens was used.
The mirror technically does flip the image in the z-axis (the direction into the mirror). If you hold the arrow pointing into the mirror, the arrow in the mirror points out of it.
The projector paper was the only visual aid that actually helped make sense of this for me. Thank you, I've been so frustrated for the past 30 minutes after seeing this on Q.I. and not understanding the explanation
