Dope Tech Episode 2

<<@varchasvaaa says : One day, I observed an optical phenomenon that I couldn't comprehend using my current understanding of light and waves. I struggled to articulate it or find the right search terms online. After few days I got this in my recommendation without even searching for it.>> <<@Octavio1123 says : 🤙🤙🤙👍>> <<@_grzehotnik says : I've been waiting 15 years for the explanation. Many thanks>> <<@StoneYellowsteve says : the background music sucks>> <<@brickbuilds0_0 says : I NEEDED THIS VIDEO BECAUSE I COULDN'T FIGURE OUT WHY DOES MT FINGERS ARE LIKE MAGNETIC>> <<@RNG-esus says : Hell yes, I've needed this information for literally decades.>> <<@Kraigon42 says : I've been mulling over this the last few days because I HAVE to wonder at what point we as a society were able to properly explain this phenomenon. I cannot imagine that, say, the ancient Greeks were oblivious to the phenomenon and yet with the flickering motion of candle and firelight it could not have been so easy to replicate and explain, surely?>> <<@JoeBlow-zr2ru says : Great video. Constructive feedback: the music is very distracting ... it's fine to have a voice without background music.>> <<@Justarandomtposeralt says : My ADHD ass noticed this years ago, and I've wondered about it until now.>> <<@MiZ1e says : Not only the shadow, your "magnetic field" too edit : he talk about it bruh>> <<@Sunghwan953 says : 나는 어렸을 때 부터 이것이 항상 궁금했었다. 덕분에 해결되었다!>> <<@ScientistCat says : I remember noticing this when I did 🤏right in front of my eye, later assumed it was diffraction around my fingertips when they got too close>> <<@최석현-w1c says : No sound, can understand. Try this guys.>> <<@GraveUypo says : one of the things i notice in school when i was 10 or so, but already figured out on my own over time in the next decades.>> <<@Abish_ says : thank you for answering my lifetime question>> <<@saltysarahzechnas638 says : Wait i still have a question! This is similar but different. Ive always noticed that shadows and light sources have a left blue edge and right red edge to them. I'll ask people about it and no one knows what im talking about. Is it the same thing as the pin hole example with the colors? You can see it in the moon VERY well. Its like some objects, shadows, or even light sources have these colored edges. I have an astigmatism, but i dont think that it affects it that much. Other than a full moon, its not very noticeable and im not sure you can catch it on camera>> <<@mcampos4115 says : Why is this different from what we saw during the solar eclipse, which proved that gravity distorts spacetime, in general relativity?>> <<@mcampos4115 says : Por que isso é diferente do que vimos durante o eclipse solar, que provou que a gravidade distorce o espaço tempo, na relatividade geral?>> <<@markplain2555 says : This is really cool. This could be used to identify the position and distance of an object (using a second object) with a single camera view instead of two or three cameras. . There is a challenge for you camera/visual programmers.>> <<@ErdrickHero says : How is it that so many things I intuited as a child are just now being scientifically explored, at least by the general public? And if I am so much better at figuing these things out than other people, why can't I find a good job?>> <<@ErdrickHero says : Congratulations for picking up on something I realized as a toddler.>> <<@fordpines1506 says : nah i thought i was bending reality or smth>> <<@bubsyboy622 says : Today I heard the word bokeh for the 1st and 42nd time :)>> <<@maikydb says : I have a poor eye sight and when i make a pinhole just the right size and hold it in front of my eye i can actualy see sharp without glasses.>> <<@MereBaapKiAulaad says : thank you, i can rest in peace now>> <<@thegrimslasher3990 says : 1:38 is that penumbra like the PENUMBRA PHANTASM!?!?!?!?!?!?>> <<@ricardobari9633 says : So cool, great explanation>> <<@sindju says : still didn't get it but cool examples>> <<@sejinkim1900 says : When I was young, I thought the magnetic shadow effect was caused by gravitational lensing.>> <<@geoffpedder says : finally an explanation! ive been wondering about this for years>> <<@b1gm0n3y says : Bro lost me but imma keep watching anyway, i understand how it works but i feel the more he explains the less im following what hes saying>> <<@best_people_in_life_are_free says : I thought we all have microgravity of our own so that micro gravitation field is bending the light or the image>> <<@f3ral2 says : So it just overlaps>> <<@Schugi2 says : I've thought about this myself, I didn't do any research, I figured it would be something with one shadow passing over the other, but there was always something missing, I did not think of a wider light source, thanks for this very (kinda uselessly) informative video>> <<@atzmut3884 says : Thanks>> <<@blupman12 says : in the wise words of Hanzo Shimada: Simple Geometry.>> <<@DUKE_of_RAMBLE says : So now the question becomes: why does what's behind the edge of your fingers/object, in that"blister", become more clear (in focus)? A better way to observe/experience this is by making a loose fist, where there's a pencil sized opening _(as though you're looking through a telescope),_ then look through it at a distant object that is otherwise a bit too far away to see clearly. *_Now_* that object is focused! This is basically a crude "peep sight" gun ""optic"", which doesn't use any actual lens.>> <<@kommienezuspadt. says : been always confused by this, thanks>> <<@coscostan3334 says : Great job, but we also need to understand why a white light turn red and blue when you apply the "magnetic shadow effect" to it. I don't know how to describe it but if you look carefully the shadow in front of the light is colored like a rainbow. Why?>> <<@cześć-hello says : i thought i was crazy when i kept seeing this, im glad im not>> <<@FilmscoreMetaler says : I think this is because the universe saved us as a jpg once when we should've been saved as a png.>> <<@numericaldust4712 says : So basically, human eyes are not perfect. As usual, what we see is not reality.>> <<@JokerGamer-iq6cv says : I find it funny because I noticed this effect a very long time ago and always wondered why does it happen and why the school doesn't teach us this kind of stuff and found this randomly recommended. Great explanation, loved the video.>> <<@mondaynoma1079 says : 1:45 the key point>> <<@Jordan-pp5bo says : THANK YOU i have noticed this FOREVER and was never properly able to explain it to people and so they thought i was crazy>> <<@timehasstoppedandthefunbeg4467 says : Yeah, nothing quantum going on>> <<@WealthSaloon says : This is the same level as the moving dots in your eyes>> <<@ammarhedar347 says : Finally i understand what happened i noted this from my childhood but was not answer>> <<@daksh_agarwal says : this would make an awesome competitive physics q>> <<@thatcringyplaneguy says : I always thought this was some kind of lensing due to either gravity or heat or something>>
