Iridescence: Nature's Most Beautiful Physics Trick 

Sending hugs!

There are ways around your colorblindness!

Yea I heard those glasses are getting pretty cheap? Like $300 or $400 I last heard or I'm making it up but it's a small price to pay to be able to see colors if you're color blind

@@RosheenQuynh For some types, not all. My best friend is colorblind, and depending on the specific type he may or may not be able to get glasses that can help. Protanopia vs protanomaly..etc

That's awesome

Do you see any human-useful applications of your life long research beyond the curious study of animals?

Glad you enjoyed it!

@@HypeHouseHomie It was an honest question although I will admit it could be read as a sarcastic response. That's the problem with written communication in general.

Well as a model of a modern major general expert in all things vegetable, animal and mineral, this is not exciting at all

From one dadless person to another (forgive the wording), I feel you, man.

I live in Adelaide. South Australia (opal country is in rural SA) and our museum displays the opalized skeleton of an aquatic dinosaur 2-3 metres long. It is absolutely beautiful. It might even feature online, it is worth a view if you can find it.

I found after death of my Dad that things like that (very personal, symbolic ones) sometimes disappear after the person is gone. I am so sorry for the loss of your father.

I found some product you're talking about yesterday but that particular brand not all of their product are like that, only some of it. So what ur looking for is already there on the market.

See Marty McFly Jr.'s cap in Bttf2. (Though I think that one's lenticular.)

Interesting

these are out there already and it looks cringe.

@@crewrangergaming9582 I agree, most products uses the color as the main focal point when it should be utilized as a lowkey accentuation point bcs the color itself is already eye catching. So using it in a big way is just overwhelming & too much, but to each their own ig.

And stoners

Scientists... are just 1st graders who have gotten older and larger.

Me too. Iridescent paints were the best purchase I made in years. Check out orchid bees!

Seems we artists have the same reaction to iridescent paint.

Lovely comment

Next! Kindly leave the stage please...

Why does alexandrite change color?

Fluoresce is actually so much cooler than anyone could imagine! To keep it fairly simple, most of us are already aware of the fact that light can exist both above and below the visible spectrum our eyes perceive as color. Inferred refers to light waves larger than what we see as Red; Ultraviolet - the key component in fluorescence - is light waves smaller than what we see as Violet. When light reflects off an object, it absorbs all but the light we see, so something red ironically absorbs everything but red, so the reflected light we see is red. This explains the vast majority of what we see. However, there are certain colors that don't just reflect back what isn't absorbed. Instead, they'll absorb some and reflect the rest back at a lower energy level. Under normal light, this simply shifts the color slightly. However, when lit with near ultraviolet light (such as a black light), the material can absorb some of it, and reflect the rest in a lower energy state. When that lower energy state dips into our visible spectrum, it often appears like bright vibrant light is suddenly pouring out of pigments which otherwise appear dimly lit. In reality, it's very well lit - but it's not until the light falls just within the visible spectrum, that you can see just how much light is actually there.

You're in for a treat! they've been making these videos for over 10 years, so you've got a lot of content just like this!

​@@fsexplorer9727 I miss when they were called 'its okay to be smart'. 'be smart' is so boring

@@samanthashuster8991 I definitely missed too. It is like "its okay to be smart" has more meaning and touches the heart

@@samanthashuster8991 You're right, definitely missed that name, it brings nostalgia just to see it again. Thankfully, you can still see it in the url of their user account I guess?

Holy cow then iridescence is like a representation of you

I think the animations were not very useful today. I would have preferred white light entering, or at least a couple of different coloured rays, so the effects of interference on different wavelengths and angles of reception could have been shown

Maybe they absorb too much light. The silica in opals is basically glass, so much more transparent particles.

I've seen iridescence on fresh clay! It was very subtle though, and only once.
