My dad had an opal ring that I used to stare at every time we talked. It looked like a galaxy on his finger set in this weirdly gaudy gold ring. It disappeared during a move shortly after he passed. One of my biggest regrets is not making sure it was in a safe place.

@SilverAura

Жыл бұрын

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.

Great presentation! I’ve liked iridescence and opalescence all my life. I have a collection of iridescent beetles I bought from a fellow I met at a craft show. He imported dehydrated ethically harvested insects from all over the world. Made the walnut frames and mounted the insects himself. My bedroom is my bug room and I love it. Now my adult kids are picking and choosing the ones they want! Gifting them to my grandkids, 11 and 6, instead. They love to sleep in Grandma’s room with the bugs. 🇨🇦🖖🏻🇨🇦

I am obsessed with iridescence lol have many minerals, crystals, insects, living creatures bc of their beautiful iridescence

I cannot believe how intriguing this is. It has been infront of me this entire time, just in my garden there are beetles and birds that have this. I never would have though so deeply about a beauty that I took for granted my entire life.

This was so fascinating. The natural world is a beautiful place. ✨️✨️✨️

I have a rainbow ammonite- gorgeous! Iridescent rainbows in the fossil; loved this!!

An illuminating video. Thank you for making such amazing content

I used to have a 2nd story balcony that looked out over a big yard; I put a hummingbird feeder on a very small tree nearby, and was delighted to realize just how gorgeous the little critters are from above--especially nice since they don't see you up there, and therefore you don't get dive-bombed by the more territorial ones! They're small and pretty, but they're fierce!

7:08 that green is just fantastic!

The science-y bit is okay and all, but man, having rocks, fossils, beetles, museums --some of the most uninteresting words --in one short video and making it interesting. You are a legend...

Amazing how the iridescent colors remain vibrant and alive even after the birds have been dead for so long .

Hi Joe, Bob here. Isn’t nature amazing! Great episode.😊

I have always loved iridescence and have many pieces in my closet that reflect this. AWESOME episode! Did I say I loved it? I think I am actually obsessed!

Wonderful images!

I wonder if there has been any study of this iridescent effect, but for frequencies below the visible spectrum? I imagine they would interfere at larger scales than these micro arrangements, right?. What would be the scale of the pits/shapes needed to create "iridescence" in radio waves? Is there a low enough frequency of radio wave, in which something like gravel or sand might become iridescent in some sense?

What is also really interesting is that our brains are capable of perceiving this beauty, and perceiving it AS beauty (as well as fascinating, and stimulating to look into the why of things, etc.)!

Excellent. Thank you

I never knew I was this fascinated about beatles.

Admittedly, I used to hate my opal birthstone and thought it was boring. Luckily they grew on me and now I love opals. Such a diverse stone

The birdwing joke flew right over my head.

It's all too beautiful!

I freaking love opalized fossils! :D they are the rarest i think

I’m confused: you mention refraction and bending several times but the diagrams only show reflection and interference. Is the bending of different wavelengths of light at different angles involved but not shown?

@FairMiles

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

My research involves studying Cyanobacteria and I have always been fascinated with the array of colors packed within these microorganisms. There is deep blue from phycoyanin, light pink from erythrophycocyanin, green from chlorophyll, and yellow from carotenes and xanthophylls. How colorful is the life on Earth!! Thank you, Joe 😀

Have to Google where I can buy opalized bones now. Loved this one. ❤️

It is a great video, thanks a lot for your work! PS Animation of light waves is a bit confusing - it's not quite correct and don't really helps to understand what's going on. I feel like it can be more detailed and educational.

We have peacocks and peahens, and in the summer we have SO many Ruby Throated Hummingbirds. I'm quite biased toward the incredible beauty of our peababies, but those hummingbirds are just as beautiful.

It's snowing in Tucson tonight. I hope our hummingbirds and finches are dealing with it well. I love both but especially the Goldfinches.

Another example of beauty is the Quetzal, in Mexico. It is so beautiful. I think it also has iridescence.

Great stuff. I do wish you had gone into more depth on the fossil ammonite since my understanding is that the nacre contains orthorhombic(sp?) crystal structures that cause the iridescence within about the top one tenth of a millimeter.

Well, good to know that the Earth and I are both fond of jewel-tones. 😉
