Calm the fuck down... Yes, but "shining laser in human eyes" doesn't sound like surgery. It sounds like "Boys playing with a laser-pointer". But yes you can use laser to carve the cornea into a lens.
Being an illustrator, this kind of stuff interests me. The thing about making each and every star the same shape once you've chosen one is something I never thought of before, but I'll make sure to never forget.
"As researchers have confirmed by shining lasers in people's eyes" Oh sure, but when i do it it's "A danger to other Delta Airline passengers" Typical...
I know i'm very late, but a combination of bitcrusher and vibrato. In digital creation, an LFO modulating the pitch parameter for the Vibrato and a basic bitcrusher VST.
Great Video Henry. I have a question about the colored star points though. Wouldn't the Red stack up with the blue and Green? Would this create something like white light towards the center, yet still allow the longer diffraction colors to "poke out" around the white? Also, I really liked the music in this video. Great job man.
I knew this about camera lenses but did not know about suture lines in the eyes, especially that no one is alike. Very cool. Could suture lines be the next fingerprint?
HungryTacoBoy Most likely. Seems that movies and stories lead the way to what technologies get developed. I think I will write a book on all the things that I want and see what comes true.
If there is the same amount of every frequency of light, then the red light will be spread out more, hence there will more blue in the center than red. So the center won't be perfectly white; it will have more blue light than green and more green light than red, and appear "blue-ish" probably.
Dude. what kind of sorcery is this? I just found answers for two different questions that I asked myself within last two months in your channel. Thank you. Very very thank you.
0:27 i have an astigmatism, meaning my eyes bend light weird and thus i can actually see those lines with regular vision. and btw an astigmatism is a normal thing
Thank you! I was driving home a few nights ago and have been trying to speculate why when I look at street lamps they have the round rainbow coloring to them (once you are close enough, otherwise you get the diffraction pattern like mentioned in the video) ! Keep up the great work, Henry. I always look forward to your next video and continue to rewatch your past ones!
Yes! Finally! I have spent so many hours squinting at streetlights and stars trying to figure this out.This has had me scraching my head for at least 20 years and finally you helped scratch that itch. Oh and does it feel good, thanks a lot! :)
Because teachers fail at delivering the material in an interesting or engaging way. Here you see a slide show with a person talking, music going etc. in class mostly books are used.
Because school physics is supposed to be about learning how to *do* physics, while things like MinutePhysics are more about presenting some of the highlights. It's sort of like the difference between an art class that focuses on teaching students to draw, paint, and sculpt clay compared to a class that focuses on the work of famous artists.
Tell me how you would teach the laws of newton as interesting as this video. It's not that school fails, it's just that it offers much _more_ and _complete_ knowledge. MinutePhysics is great, and it is motivating, but it will never teach you how to do physics.
I've been wondering about the rainbow coloring thing for quite some time now and never bothered to look up the reason. I am incredibly near-sighted, and so I wasn't sure if that was the main cause of it or not. I am pleasantly surprised to have learned the answer to that particular mystery. Thank you.
I think its supposed to represent two organ hearts put together (side by side, you can probably find an image), which explains why it is a symbol of love
Human hearts have a different shape. But look at a crocodile's heart. Egyptians used this shape because of that. It might have spread throughout the centuries. dfzljdn9uc3pi.cloudfront.net/2013/60/1/fig-2-2x.jpg
I can answer that. The dented shape of the heart is actually based off of the leaves of popular medieval plants, like ivy, water lily, and bohdi leaves. Such leaves were often implemented into medieval and Renaissance Christian artwork as symbols of love, and were eventually combined with the more anatomically-correct symbol of "offering your heart" to someone. Thus, we now associate hearts with romance, and romance with the dented, cartoony version of the "heart."
Behind TheWall Ha, that's true, but from studying medieval art, the transition from using a literal, anatomically correct heart to using leaf shapes to represent love seems pretty clear. If there's anything I learned from two years of art history and medieval culture, it's that... and also how to talk like an old-timey asshole.
LloydieLynn "transition from using a literal, anatomically correct heart to using leaf shapes" Are you saying we actually found medieval art of anatomically correct hearts being used like that or that you're deducing it? Because if we found that, awesome let me see!
Behind TheWall Well, "anatomically correct" for the time, at least. Here's a picture of a knight giving a chick his literal heart. Like, from his chest, not just his love: upload.wikimedia.org/wikipedia/commons/7/7f/Roman_de_la_poire_heart_metaphor.jpg Here's a painting from the 1700s depicting Jesus' giant, magical heart. This one manages to be somewhat cartoonily "heart-shaped" and also more or less anatomically correct: en.wikipedia.org/wiki/Heart_%28symbol%29#mediaviewer/File:Sacred_Heart_1770.jpg It also has a crucifix coming out of the main artery! Pretty exciting stuff.
I knew it had something to do with the eye! I remember blurring my eyes, and looking at points of light coming from a few LED's close to each other. Each blurred LED light had exactly the same shape blur to it, with the little lines and ridges etc.
Thank you for this video, you just got yourself another subscriber. Not only did I learn something about my own eyes and about how light works that I genuinely didn't know about, but I also was given a good website to help me save money while I'm currently in college. Keep up the good work, I love all that your channel produces.
Thank you so much. You actually answered a series of self made questions I had today about the refraction of light trough curved glasses and those 'tiling shaped openings not seen quite often-windows', and left a smile on my face. Greetings :)
Henry, can you please write like an actual textbook? Not just one that lets us grasp shockingly complicated concepts with shockingly little background, but what if you actually taught those concepts too? I'm rather smart, if I weren't I wouldn't have made the academic accomplishments I did... but some overwhelmingly disruptive life events kept me from finishing my education. Actually I almost died a few times... but I know that I could ACTUALLY grasp these concepts if Henry were doing the teaching. Please Henry. You're too valuable. I don't want to squeeze you like a golden goose (is that how one operates a goose? I don't know, I am not a goosesmith), but I must make my wish known.
This is easily my favorite episode, for both the choice of music and the topic you picked, as well as how you edited it. Very well done! Thats how i like to learn more about physics at 10PM :)
As a little kid, I always wondered why stars are referred as ★ . Besides the fact that stars are actually round balls, they unmistakably look round in the skies. Thinking of that, same goes for heart-shape... heart doesn't look cute like a heart shape
I love learning about physics because it helps so much with painting and art in general. Many people dont realize it but its absolutely vital to learn some basic concepts of physics to be able to make astonishing art.
Why are there so many flame wars in the comments? Seriously haven't people learnt that the internet isn't a good place to discuss: religion, political and ethical views? Especially when it has nothing to do with the video.
Your voice is AWESOME. Watchin' your vids since... I think "there is no pink light", but I never noticed the awesomeness of your voice before. Keep up the good work!
Waaaaait. did he just say *It's actually surprisingly simple?* Where did i hear that? Umm.. Oh now i remember! The video i just watched! I got someone's identity.. That's where he gets his contraptions! *Hoo-rray!*
You are referring to 'astronomical seeing', the blurring and twinkling of stars as seen from the surface of the Earth, caused by the mixing of the air above refracting the light over time. Long exposures of stars from cameras on the ground need 'adaptive optics' to remove our friendly atmospheric distortion. Henry's topic of star optics is just one of the many factors that change the way stars truly look, and all of them are super intriguing! Science kicks ass. Keep your eyes on the stars, and your feet on the ground!
Stars aren't perfect spheres but so close the most spherical thing (a silicon sphere created by the EU to measure how much a KG is) is the only thing more spherical.
For all of you saying that science is an atheist practice and thus isn't true, it's not. Science is a secular practice, meaning that religion is, at least ostensibly, not involved in it. Not all scientists are atheists (in fact, quite a number of them practice some form of religion, myself included).
That bit about 'suture lines' in our eyes has answered a question I've been asking since I was a kid. I notice the diffraction particularly well with car headlight, and the large yard-lights that are used on farms.
***** Duuuuuude NICE work on the word ''oasitic''. Not gonna lie I had to drop the Google bomb on that but I don't feel too bad because even spell check was like WUUUUT? Must be nice being smarter that my computer haha :D Now unfortunately TH-cam doesn't provide me with a two thumbs up button :( So I had to settle for one, but we both know better :) Cool name, cool picture, cool word I shall take it with me. Hope you are havin' a good'n XD
Again (as always), I read the title and think "Oh, I know this, but I'll watch it anyway..." and then learn something new and awesome. Thanks for teaching me something every damn time. Cheers.
It's because there are actually a lot of cuts in his videos, with a new take happening with nearly every sentence if you look at some of his behind the scenes videos.
+Michael Meissner is that because there was purple in the middle, and rainbows don't technically have the color purple? maybe he was drawing the perceived purple from the red of the rainbow within the bigger rainbow.
If we're being totally correct, god didn't make anything at all, ever. I'm sorry, but if you're asking a question looking for the truth, I'm going to give it to you.
Sontraid This is like saying, "We can say for certain whether dragons exist or that we made them up, like god, so they may exist and people may have killed dragons in the past. There are books that claim that knights killed dragons."
playnow254 They're too fast to run from!! We need to make peace with them before it's too late!! The revolution is upon us.. My girlfriend, in failing to read my mind, has resorted to asking me what I'm thinking about every 5 fucking seconds.. Something is up I can feel it.. I'm.. I'm scared..
What a great explanation. Only one thing to add. There is a better chance of seeing stars as "star" shaped as vision deteriorates and the image on the retina is slightly out of focus. The effect is greatly enhanced
You should write them a letter warning them. I'm sure the professional scientists will highly appreciate the wisdom of a random kid on TH-cam in their own field.
It is, when you study at the quantum mechanical level, since you can't measure the exact time something arrives if you're certain of its energy, and vice versa. We just use the photon representation because it's easier to work with on the macroscopic level.
It's both a wave and a particle. Waves don't have momentum (light does, go look), but particles don't act the way light does in this video, with the whole hole thing.
playnow254 If light is a wave and waves don't have momentum, light having momentum is a contradiction ;) One of those statements has to go and I'd vote for "waves don't have momentum" since light is the obvious counterexample. Light _is_ a wave and light _is_ a particle which is why ***** basically attacked a strawman.
"We know stars are actually big round balls of plasma" Shows a false color image of a star that makes the surface look way more splotchy than it should, and completely the wrong color.
Oh no, this totally ruins the video! And in no way can we see in a false-color-picture, that makes the star seem more splotchy, and false-colored, mind you, that it is big, and round! /sarcasm
False color image is there because the real color would be mostly white with hints of white. It is hard to see the structure of the sun with all of it's solar flares and plasma gymnastics by just looking at the sun the same way that we do. Go ahead and try, look at the sun and see if you can see those things. I bet you cant. (It's harmful, so please don't, actually). If you want an accurate picture of the sun, based on what we would see at that magnification, take a piece of printer paper and look at it. That is all you could be able to make out. Also, the surface is that splotchy. That is reality, if you could dim the sun enough. And again, the color is so that you can distinguish the quirks of the surface of the sun, and not just see white on white.
Thank you soo much for the SlugBooks com link, Henry. You've given me an opportunity to save a ton of money for my future semesters. By the way, your videos are awesome.
Faith has nothing to do with a lack of belief. To be clear I am not trying to be rude so bear with me. First of all; you seem to be confused on what faith means. This is very easily remedied by looking in a dictionary or google. Put in the simplest terms, faith means to believe in something for no good reason. The key word there is believe. Since disbelief is the antonym of belief it by definition cannot be faith. Like wise if I where to say "Why do people disbelieve there is no God when they logically can't prove it? Isn't that Atheism?" I would essentially would be making the same mistake as you. Also you need to understand the concept of burden of proof. Basically it is the responsibility of the person making the positive claim to prove there point. This is because if we accept that the person making the negative claim must accept the burden then you end up in a situation where the conversation cannot progress. Let's say you don't believe something's real, could be anything at all really. Now ask yourself why you don't believe it. The likely answer is that you have never seen evidence or had reason to believe it to be true. Now I come up to you and try to tell you that said thing is real. When you ask me to show evidence I then say that you should tell me why you don't believe and that if you can't logically prove that there is no way it is real then I must be right and you must be wrong. But if you have simply never seen said thing and it turned out to be real then it's likely that if you just seen the evidence you would start believing it to be real. This is why the burden of proof is on the positive claim. If it is true it is possible to prove, but if it's untrue it is nearly impossible to disprove. Again not trying to be rude or insulting to you or your beliefs. I genuinely just want help the best I can. So the TL:DR version. No.
heres why: If right now all of the science and religion vanished, slowly, over time mankind will recover all of science. religion as we know it however, is gone forever. no one will rediscover christianity. people will make new imaginary gods to explain what science hasnt yet answered.
Why do people believe there *is a* God when they can't logically prove it? A void of specific logic will lead to people filling in the blanks with their beliefs.
im taking an intro to optics class at my university and one of our labs explored the FT patterns of laser beams! I noticed the patterns on the fourier plane looked suspiciously like stars and searched this video up! great video #welovesciencelol
***** It's you again. You commented on my other comment. Honestly, if you can't tell from the internet speak and emoticons, my comment was a joke. Literally, after making a harmless joke you somehow see it as me being triggered and start rambling on about my past and therapy? Sounds like you're really getting triggered. Just chill out man.
“every single eye on earth will see a slightly different starlike smear depending on the exact nature of the suture lines” so scientific yet so philosophical….. i love it here
one of the weird and cool things about diffraction is you can use the star image to test the quality of the optics in a telescope. You observe the concentric rings (typically only the first ring is visible, the other rings are much dimmer unless there's severe distortion) and shape of the central dot when in focus, and you observe how the pattern changes as you watch the star's disk expand when moving out of focus in either direction. astrophotographers use such things as "Bahtinov Masks" to create diffraction spikes visible in the telescope which will only be perfectly centered when the telescope is in focus. (this is typically not necessary for visual astronomy as the eye can compensate for small amounts of defocus) also drawing stars the way you've done them as "scientific accuracy" is like saying the Sun is green because its peak wavelength is in the green. It may be based in science, but it's still a simplification--the "realistic" way is to, well, draw them as little tiny dots with small spikes coming out of them. (Just as the Sun is, in fact, a white ball)

physics can be so awesome, but why is school physics so booring?
Because teachers fail at delivering the material in an interesting or engaging way. Here you see a slide show with a person talking, music going etc. in class mostly books are used.
Because it's designed to reach exam board check boxes and quotas, not to actually educate young people on the universe around them.
i mean we had a lot of cool subjects like nuclear physics, but why can't teacher make it interesting?

distort, not diffract.

Stars aren't perfect spheres but so close the most spherical thing (a silicon sphere created by the EU to measure how much a KG is) is the only thing more spherical.
xXxXComputrisedCupcakesXxXx Since when did i say perfect sphere?
Since when did i ask you what the most spherical object is?
Since when, did i care?
Madao
Since you crossed over into.. The Twilight Zone.
funky3ddy xD
*Throws Neutron ball at funky* No one talks of twilight NO ONE EVER.
This video has 2.5k like right now, how is this possible when there are only like 4 people on earth? im calling bots right now smh
HAHAHAHA, no
Last time I checked there are 3, not 4.
All the people are watching it over and over again on a thousand computers or so
Its 3
If you guys dont get the joke he ment three and they are Me Myself and I
Next you're going to tell me that hearts aren't, well, heart shaped.
They are, vaguely.
It actally said that Leonardo sawed a leef (or a butt) que and maked a drawing of it
Qnd the chuch was like: i'm keeping this
glad to see you are posting more frequently now, thank you
I really like the music and art style to this video. Keep up the good work Henry.
so everyone sees stars little differently :) COOL
For all of you saying that science is an atheist practice and thus isn't true, it's not. Science is a secular practice, meaning that religion is, at least ostensibly, not involved in it. Not all scientists are atheists (in fact, quite a number of them practice some form of religion, myself included).
I can still just draw different shape of stars---------------just claimed that they are watched from different people
That bit about 'suture lines' in our eyes has answered a question I've been asking since I was a kid. I notice the diffraction particularly well with car headlight, and the large yard-lights that are used on farms.
"As researches have figured out by shining lasers in peoples eyes." All so casual like yeah, sure, that won't burn the retina. XD
+Elizabeth Darons Laser Eye Surgery? Sometimes Burning The Retina HELPS The Eye
+Elizabeth Darons Perhaps it was a very low intensity laser.
"Researchers"...
Hey, person reading this, I hope you realize just how much I love you.
Aww, thanks!
***** You are more than welcome, internet type lovely person :)
bcuzfaqudatzy Oh u...
***** Duuuuuude NICE work on the word ''oasitic''. Not gonna lie I had to drop the Google bomb on that but I don't feel too bad because even spell check was like WUUUUT? Must be nice being smarter that my computer haha :D Now unfortunately TH-cam doesn't provide me with a two thumbs up button :( So I had to settle for one, but we both know better :) Cool name, cool picture, cool word I shall take it with me. Hope you are havin' a good'n XD
love you too baby ;3
From my balcony sometimes I see a star that looks like it's blinking between green and red? why is that?
David Batista That's a plane
+MrPicklepod lol no, it stands there, perfectly still, all night, in the same spot every night
+David Batista Traffic light.

"that researches found by shining lasers in peoples' eyes" I always get in trouble when I try to be a researcher ._.
Again (as always), I read the title and think "Oh, I know this, but I'll watch it anyway..." and then learn something new and awesome. Thanks for teaching me something every damn time. Cheers.
“As researchers have confirmed by shining lasers into people’s eyes” is an extremely concerning sentence out of context
Why do you talk in staccato.
Because it makes his diction clearer than if he spoke in legato, I assume.
Because music is the best language in the world
It's because there are actually a lot of cuts in his videos, with a new take happening with nearly every sentence if you look at some of his behind the scenes videos.
Nillie why not potahto
Heireau Melons In musical terms, _legato_ is the opposite of _staccato_.
Why did you color them in with such scientifically inaccurate rainbows?!?
Supernumary hue.
Roses are red
Some other roses are orange and shit
The rest of the flowers are colors
The end
+Michael Meissner is that because there was purple in the middle, and rainbows don't technically have the color purple? maybe he was drawing the perceived purple from the red of the rainbow within the bigger rainbow.
+LittleFoxFan Presents
Roses are an assortment of colours.
Violets are violet
I fucking hate this rhyme.
So god didn't make them that way,it's just laws of nature?
If we're being totally correct, god didn't make anything at all, ever. I'm sorry, but if you're asking a question looking for the truth, I'm going to give it to you.
mrturtleguy23 If we're being totally correct, we don't know for sure whether god exist or not. So why not leaving people in their believes?
Sontraid This is like saying, "We can say for certain whether dragons exist or that we made them up, like god, so they may exist and people may have killed dragons in the past. There are books that claim that knights killed dragons."
Sontraid We dont know if God exist or not, but we do know the Bible is a fairy tail.
Sontraid Same reason you don't let children believe in Santa forever. It's cruel.
Not that I ever believed in Santa in the first place though.
Excellent Video! One of the best definitely.
Very Interessting case, good questions/narrative, and clear explanation.
Thank you!
MinutePhysics, we need more frequent videos.
Att,
A big fan.
This is wrong. My priest told me that's just how god made the stars 10,000 years ago, and we were made to see them that way.
well now we know where all Eliza's crack has gone.
Obvious troll or delusional idiot.
Either way, a significant underachiever.
Please try harder.
Animuldok Wait, if I'm an obvious troll, then why did you put "or delusional idiot"? Maybe it's not so obvious.
I agree with Animuldok. but I have a question. Why do you troll nigel? Is it fun?
Makes more sense like this.
"Obvious, (troll or delusional idiot).
Either way, a significant underachiever.
Please try harder."
0:49 that noise/voice in the background is really creepy
noticed this too.
Oh thank god other people noticed
stars were simple creatures before i watch this video

Holy shit THANK YOU SO MUCH FOR SHAREING SLUGBOOKS WITH US
. This is the thing I've needed since I started college
keep doing what you are doing please, this stuff is food for my soul.
god is truly amazing
Lol.
lul
Isn't she?!
bcuzfaqudatzy Good sir, you have invoked the terrifying power of the woman. Remember, women are always right. Run.
playnow254 They're too fast to run from!! We need to make peace with them before it's too late!! The revolution is upon us.. My girlfriend, in failing to read my mind, has resorted to asking me what I'm thinking about every 5 fucking seconds.. Something is up I can feel it.. I'm.. I'm scared..
Heart attack at 0:51
*******
Ba dum tss!
What a great explanation. Only one thing to add. There is a better chance of seeing stars as "star" shaped as vision deteriorates and the image on the retina is slightly out of focus. The effect is greatly enhanced
Please never stop making videos beautiful work.
Scientists shined lasers on people's eyes? Isn't that dangerous?
Depends on where and ho you shine them as well as, obviously, the intensity of said lasers.
They perform eye surgery with lasers. The lasers are used to deconstruct or reshape irregularities in the eye.
Breadfan AND IT'S AWESOME, at least for me it was. FREEDOM.
You should write them a letter warning them. I'm sure the professional scientists will highly appreciate the wisdom of a random kid on TH-cam in their own field.
Light is not just a wave
It is, when you study at the quantum mechanical level, since you can't measure the exact time something arrives if you're certain of its energy, and vice versa. We just use the photon representation because it's easier to work with on the macroscopic level.
it this particular circumstance it has** to be represented as a wave
It's both a wave and a particle. Waves don't have momentum (light does, go look), but particles don't act the way light does in this video, with the whole hole thing.
playnow254 If light is a wave and waves don't have momentum, light having momentum is a contradiction ;) One of those statements has to go and I'd vote for "waves don't have momentum" since light is the obvious counterexample. Light _is_ a wave and light _is_ a particle which is why ***** basically attacked a strawman.
Penny Lane Okay, how about, waves that don't move through matter aren't affected by gravity.
"We know stars are actually big round balls of plasma"
Shows a false color image of a star that makes the surface look way more splotchy than it should, and completely the wrong color.
Oh no, this totally ruins the video! And in no way can we see in a false-color-picture, that makes the star seem more splotchy, and false-colored, mind you, that it is big, and round! /sarcasm
False color image is there because the real color would be mostly white with hints of white. It is hard to see the structure of the sun with all of it's solar flares and plasma gymnastics by just looking at the sun the same way that we do. Go ahead and try, look at the sun and see if you can see those things. I bet you cant. (It's harmful, so please don't, actually). If you want an accurate picture of the sun, based on what we would see at that magnification, take a piece of printer paper and look at it. That is all you could be able to make out. Also, the surface is that splotchy. That is reality, if you could dim the sun enough. And again, the color is so that you can distinguish the quirks of the surface of the sun, and not just see white on white.
its still a picture of a big round ball of plasma so no problems there.
I don't think it is a false colour image, dimmed by few orders of magnitude, sure, but Sun does look exactly like that on movies from SOHO and STEREO
The colour really isn't important.
I thought the music for this one was really great! please keep posting videos, we all love to learn! :D
Thank you soo much for the SlugBooks com link, Henry. You've given me an opportunity to save a ton of money for my future semesters. By the way, your videos are awesome.
Wtf... 0:50
Can someone please explain this?
Yay my stars can be gay like me
Why do people believe there is no God when they can't logically prove it? Isn't that faith?
Because we dont, and the gods that we do claim don't exist have a liklier explaination for their origins
Faith has nothing to do with a lack of belief. To be clear I am not trying to be rude so bear with me. First of all; you seem to be confused on what faith means. This is very easily remedied by looking in a dictionary or google. Put in the simplest terms, faith means to believe in something for no good reason. The key word there is believe. Since disbelief is the antonym of belief it by definition cannot be faith. Like wise if I where to say "Why do people disbelieve there is no God when they logically can't prove it? Isn't that Atheism?" I would essentially would be making the same mistake as you. Also you need to understand the concept of burden of proof. Basically it is the responsibility of the person making the positive claim to prove there point. This is because if we accept that the person making the negative claim must accept the burden then you end up in a situation where the conversation cannot progress. Let's say you don't believe something's real, could be anything at all really. Now ask yourself why you don't believe it. The likely answer is that you have never seen evidence or had reason to believe it to be true. Now I come up to you and try to tell you that said thing is real. When you ask me to show evidence I then say that you should tell me why you don't believe and that if you can't logically prove that there is no way it is real then I must be right and you must be wrong. But if you have simply never seen said thing and it turned out to be real then it's likely that if you just seen the evidence you would start believing it to be real. This is why the burden of proof is on the positive claim. If it is true it is possible to prove, but if it's untrue it is nearly impossible to disprove. Again not trying to be rude or insulting to you or your beliefs. I genuinely just want help the best I can.
So the TL:DR version. No.
heres why: If right now all of the science and religion vanished, slowly, over time mankind will recover all of science.
religion as we know it however, is gone forever. no one will rediscover christianity. people will make new imaginary gods to explain what science hasnt yet answered.
I cant logically prove that there are no Dragons, therefore I put god in that same category
Why do people believe there *is a* God when they can't logically prove it?
A void of specific logic will lead to people filling in the blanks with their beliefs.
Thanks for the longer/more in depth video!
You guys and asap science are the best I've seen
im taking an intro to optics class at my university and one of our labs explored the FT patterns of laser beams! I noticed the patterns on the fourier plane looked suspiciously like stars and searched this video up! great video #welovesciencelol
FT. ANATOMY AND PYHSIOLOGY MINUTE PHYSICS YOU ARE AWESOME
Jesus did anybody get scared by the distorted voice. Plz MinutePhysics, I love your calm, peaceful, videos. D:
***** It's you again. You commented on my other comment. Honestly, if you can't tell from the internet speak and emoticons, my comment was a joke.
Literally, after making a harmless joke you somehow see it as me being triggered and start rambling on about my past and therapy? Sounds like you're really getting triggered. Just chill out man.
"As researchers have confirmed by shining lasers in people's eyes"
dam physics can be brutal sometimes
I JUST thought about this the other day watching a program about the Hubble and James Webb. Thanks for saving me tons of Googling time.
I've learned all this from Astronomy. One of the best classes I ever took.
I can't believe more people don't watch minute physics. It really puts everything into perspective
“every single eye on earth will see a slightly different starlike smear depending on the exact nature of the suture lines” so scientific yet so philosophical….. i love it here
Great explanation to one of my questions when I was a kid. Awesome that every body see's the stars in different ways.
Wow! I didn't know any of this things, thank you minute physics for teaching me all this stuff :)
That's just awesome, how your friend one the best games of all time. Kudos to you and your friend!
As a physicist, this video is your best one IMO.
I saw this video 9 times more just to listen to that soothing background music. :')
one of the weird and cool things about diffraction is you can use the star image to test the quality of the optics in a telescope. You observe the concentric rings (typically only the first ring is visible, the other rings are much dimmer unless there's severe distortion) and shape of the central dot when in focus, and you observe how the pattern changes as you watch the star's disk expand when moving out of focus in either direction.
astrophotographers use such things as "Bahtinov Masks" to create diffraction spikes visible in the telescope which will only be perfectly centered when the telescope is in focus. (this is typically not necessary for visual astronomy as the eye can compensate for small amounts of defocus)
also drawing stars the way you've done them as "scientific accuracy" is like saying the Sun is green because its peak wavelength is in the green. It may be based in science, but it's still a simplification--the "realistic" way is to, well, draw them as little tiny dots with small spikes coming out of them. (Just as the Sun is, in fact, a white ball)
Your videos are only getting better.
