Beyond what we can touch, taste, smell, and hear, we experience the universe through light. But how did we come to discover light, and how did we learn light’s true nature, as the fastest thing in the universe, an electromagnetic spectrum, a wave and particle capable of the most amazing things? Here is the history of light, according to physics.

ØØØØØØØØØØØPS!
I accidentally called Ole Rømer Dutch. He is Danish. Very sorry for the error!
It's Okay To Be Smart damnit I thought we finally achieved something in Holland...
ah, well, we still invented the microscope, thats something
iPhil dutch > danish is the difference
+iPhil Careful there!
Im dutch, but i dont mind the mistake. Danish people are awesome!
+Seameus True.....
Science: "Is it a particle or a wave?"
Quantum Theory: "Yes."
My girlfriend should be named Quantum Theory.
😂
Junaid . Is it because she exists to you but to no one else?
And according to Quantum Field Theory, waves, UNTIL one measures the field, THEN you see a particle.
@@heavyhoved Humans are not part of quantum theory, therefore measurement is not part of quantum field theory either. The only part that exists is waves.
This week's video is a little light history lesson. Hope it brightens your day!
It's Okay To Be Smart that pun. 😂
sir can the next video be on physics
It's Okay To Be Smart HAHAHAHAHHAHAHAHAHAHAZHZHZHAHZHAH
Because of light, I will have 20/20 vision in three years.
DO WHAT WOULD HAPPEN IF THE ASTROID BELT CRASHED AND BECAME A PLANET
EDIT: PLEASE
Teacher caught me watching this at school, he was like "NICE!"
They should show this instead of those boring videos that no one actually watches.
@@stralax57 ikr
Lol
Noice
@@stralax57 most of those boring videos are too boring to teach me anything
"Our eyes shot out light."
And then the Sun sets.....
@Andrew Friend What if sun is like a magnifier to enhance your vision? People see some stuff in the dark but not as much.

OHHH MY GOSH UR AMAZING
i am walking on a flat Earth shining light out of my eyeballs.
The flat Earth society is located all around the globe.
Both comments are gold.
Spairus
you scared me i thought i commented that and was the most confused in my life for like 1 picosecond
lol there's also another top comment with our profile pic
Yea... NO
I love how the minute details are introduced so subtly! For instance, the different 'glowing idea lights' on each person were according to their time! Loved it! :)
Can we get an "I did a science" shirt?
I thought there already was one
there is
I think you have to do a science first.
@@lessonslearned6760 understandable

This video was very enLIGHTening!
I'm sorry
No you’re not
You should be.
You should "see" yourself out!
I don't feel enlightened, I think you're stupid.
"Is light a wave or a particle?"
Yes.
both
@@gauravproton1956 r/woooooosh
Yeah well, I know I am late to the party...but wow! Having the entire history explained to me in a 6 minute window rather than over the period of four grades--was really helpful and I loved it.
We discovered it because some dude was board and said "Let there be light!"

I was always inquisitive about what was light and what developments actually led to the electromagnetic spectrum.Thank you so much.This was wonderful.
I've been a subscriber for a while, and I think this is one of most well-presented videos you have done to date.
Misa: i would never dream living a world without light
L: yes that would be dark XD
shut up fcking weeb
well thats toxic
Just reading that, i can see that scene playing out. Awesome show.
@@tazztazztazz0855 bruh, you have a profile pic of Futaba (an anime character) smh
it's absolutely incredible.. we wouldn't have any of our technology today without these discoveries with light..

This has to be one of the most enLIGHTening episodes of IOKTBS. I really mean that; the video deals with a subject and matter that most of us deal with every day, and it deals with the topic in the most basically understandable way possible. Kudos to you, Dr. Hanson. Keep on keepin' on!
Thanks for the great video. I love how the 'idea' light bulb over each scientist's head is a light-source that was used at the time.
this is my favorite video in this channel so far!! absolutely amazing
I absolutely loved it. I love how how anchor it very much. Love the videos.
so next u gonna tell us how this led to quantum theory? and the history of it
Daggeress yeeeeeeeesssss
This was a very well told story. I knew (approximately) all of its parts but it's the first time I see someone put all of them together like It's Okay To Be Smart did here. It definitively add something to my comprehension of what light is.
Great video! So much information in such a short period of time and yet so clear! Thanks!
best video i saw till now about the topic thanks for making it so succinctly!
hes one of d best....though i learnt dis already in my high school... i realized many things and even understood connection between many chapters and people!!
Haaa ! This is so amazing ! I love to hear about all this scientific breakthroughs, achieved in ways I hadn't thought about :'D
I wish theses videos would be use in classrooms... so much info in little time! Love it!
TRULY AWESOME EPISODE. kudos to the animation department too!!!
I really like the frames/clip starting at 5:11 because I feel it helps to visualize particle-wave duality.
Really awesome production quality. I would love more videos just like this one.
Thank you! We always try to make every video better, hope we can keep moving the bar up
7 minutes video by "It's Okay To be Smart = 7 years of education in my country.
I love this channel.
Your profile picture is deeply disturbing.
Yeah, I know. They took my that one after my surgery. But I look much better now
realy well done!
loved the animations
very well moderated, spoken in a exciting way (and not overblown)
can't wait for #2
BTW. what about merch or winning stuff while living outside of the US ? (Europe)
Your session answers Tons of Questions.......Thanks
Awesome video! Loved the animations and little details.
Great video mate, gonna use this in my physics lesson today :)
out of the all your videos this one is my favourite the language used & the way it was presented is easily understandable a big thumbs up for you my dear bro
YOU ARE THE BEST SCIENCE COMMUNICATOR EVER !! There should be an award that you would win ... Thanks for making these videos !!!
dude! I love your videos! thanks for doing them!
THIS VIDEO HAS BEEN THE MOST INTENCE VID SO FAR! I had to rewind it x3 TIMES!!!!! And I love this science stuff!!!!!
Outstanding video and superbly well narrated.
One of the best episodes. Thank you.
I really enjoyed this history of science video, can you do more of these please? I used to have a history of math book and it was great.
Good timing! I'm doing exactly this in my physics classes at college
0:18 Greeks figured out ray tracing 3000 years early
That was fun to watch! And informative!
You’re the best. Very good video, intelligent, entertaining, interesting and great delivery.
hey Joe. really good content in this one. congrats. wish you all the best.
Wooow...thank you for explaining it the best possible way👍👍
Great video! I love the animations!
Great episode. Well researched.
It's a common mistake among non-europeans but Ole Rømer was Danish not Dutch. As a Dane I feel compelled to point that out.
+Christoffer Vincent Thon Dang. To all Danes, please accept my apologies for that error. Copenhagen is one of my favorite cities ever. Danish people are wonderful. I owe you all one.

"Common mistake" is a bit of a stretch. I've never heard of him.
Im neither Danish nor Dutch, but I still feel you owe me one.
WOW I "ACCIDENTALLY" FOUND THIS.....I LOVE LOVE THIS. THIS IS FANTASTIC!!
I love its animation as well as its concept. Keep it up bro.
These are incredibly well done videos...
This has been the most epic video so far!
Just taking out the time to appreciate the amazing animation 😍
wow the best explanation of the electromagnetic spectrum.
4:55 I think Max Planck had an idea that light travels in quanta at least 15 years earlier than 1918.
Amazing video and visuals!
best video ever! cool animation, nice voice 😘, and an interesting topic. keep working this hard
super job this vedio actually helped me a lot in understanding
my post graduation lesson
thank you Mr. Jo 4 this vedio
This got me so excited for some reason.
Man, love your videos!
I must say, This video was pretty illuminating!
5:20 you've gotta love the animations on this channel.
And the stupid jokes too :D
You almost made the quantum chemistry I learned actually interesting.
Nice graphics btw.
This was most illuminating!
Just to point out something about Max Planck, he actually presented his idea about quanta of light in 1900 but he did get the Nobel prize in 1918. I'm sure that's what you meant by "1928" on the timescale but still wanted to clarify that ! Great episode btw
Beautiful
more like this please!
Wow brilliantly explained 👌
I can not comment every video,but every episode is amazing...Thank you. From junior scientist
one of the best episode, after the 12 days of evolution. thanks for the best videos you provide which is great tools to help teens&kids understand the beginning to the end(of current knowledge/vision)
Thank you for educating me
awesome video as always!!!! :-D
loved your animation
Great video, one of your best videos.
Thanks! I can't pick a favorite but you are certainly allowed to
Great episode!
You're enlightened me!
You guys should do more videos on how did we figure out on other inventions and their history(TIMELINE). Great video, hope to see more similar videos.

This video gave me goosebumps
Today I Learned something new! :D
I didn't know that the ancient Greks thought we had flashlights inside our eyes. ;)
Very very interesting video!
Really good episode.
This video is your best one ever!
Nice video. Correction for the photoelectric effect: the reason why it could only be explained by light being a particle and not a wave is because when we use too low frequencies the photoelectric effect does not occur at all. If it didn't have anything to do with light being a particle, we would expect electrons to build up energy and get kicked out anyway. Or maybe increasing intensity of the low frequency light would do the trick, but it's not what we observe, therefore, particles.
at least ancient Greece had X Men.........
Where did you get the year 1918 from, regarding Max Planck's and Einstein's discoveries? Planck initially (in 1900) considered quantization to be only a mathemathical trick (i.e. did not speculate too much on the physical significance) to solve the problem of blackbody radiation, and Einstein wrote the paper on the photoelectric effect in 1905. Might be nitpicking, but I'm still curious.
I was gonna make the same remark when I noticed yours.
5:24 Next level satisfying
Well this is an enlightening video
Kwel. I enjoy videos like this, thanks! 💜
love this channel
Hello , your videos are awesome man, how are you so Regular with your videos please give some tips :)
Very infomative
Excellent video.
one of the few times i ever remember advertising working on my i am so close to going to curiosity stream but uni is a pain
Love the video, random question, I know the music is from APM but what's the name of the track?? Thanks!
Great video!
Have a question tho, what do you mean when you say that al-hayzam is the first scientist? What did hist experiments had that make him a scientist and for example Arquimides wasn't?
After watching 30 or so episodes of this channel in 4 days, I've started wandering - am I that into science or just into the guy who's hosting the show :?
