Color drops

Engineers at MIT and Penn State University have found that under the right conditions, ordinary clear water droplets on a transparent surface can produce brilliant colors, without the addition of inks or dyes. (Learn more: news.mit.edu/2019/water-drople... )

The Massachusetts Institute of Technology is an independent, coeducational, privately endowed university in Cambridge, Massachusetts. Our mission is to advance knowledge; to educate students in science, engineering, and technology; and to tackle the most pressing problems facing the world today. We are a community of hands-on problem-solvers in love with fundamental science and eager to make the world a better place.
The MIT UA-cam channel features videos about all types of MIT research, including the robot cheetah, LIGO, gravitational waves, mathematics, and bombardier beetles, as well as videos on origami, time capsules, and other aspects of life and culture on the MIT campus. Our goal is to open the doors of MIT and bring the Institute to the world through video.

Colorless coloring

I think my favorite part is that they used music with a 5/4 time signature!

[@MikeTrieu]

Structure-based color displays have already been created with vertically-aligned plates in a so-called interferometric modulator. It would be interesting to see someone commercialize a similar technique using this hemispherical method with total internal reflection and electrowetting principles to change that exit angle dynamically.

Im really hoping to get into M I T when I am older and have a good experience with tech and I love coding and building pcs and many things. I LOVE TECH.
hopefully I will see you guys later!

Curious how it ended out! Did you get in?

[@ustopian]

These results are polarizing 😉

[@Volker_A4]

That looks amazing

[@ncknelson]

Our Team of Engineers.........lol

[@SaposJoint]

Now engineer a substrate that can change the radius of the droplets, and you can sort of mimic chameleon or cuttlefish. Nice.

[@danphillips8530]

That is mind bending

Or transparent screens

[@coryr9567]

Interesting, but curious how this plays out in a world increasingly dominated by LED lighting? Sure in full sun or full spectrum light, you can generate a full rainbow of color. Do you get the same effect if the lighting only has a few spectral peaks?

[@charlottelucas5714]

this is fascinating! the prospect of not using chemicals could eliminate the need for animal testing!! so pretty

Thats MIT for ya..

[@robertschlesinger1342]

Amazing and interesting, but why did this phenomena take so long to be discovered and explained. Optics at a reasonable level of scientific understanding goes back to Newton. This also shows that there are basic discoveries still waiting to be found, explained, and applied.

[@abhilashch2189]

I partially agree and disagree. This is not a new discovery, these phenomena are explored and their natural occurrences have been reasoned. But, we are equipped now with, previous generations were not, sophisticated instrumentation to produce droplets of the same size, again and again, to allow them to stay stable, computation power to make simulations to do predictions, etc. So, the whole thing can be seen as redoing what is already known with better instruments. I accept that there are still basic discoveries waiting to be found.

I have no other point to add to this already precious conversation. Just wanted to applaud both of you while creating a long paragraph myself. Hope I delivered it.👏

[@adeline4610]

Thank you! I agree.

[@adeline4610]

@@abhilashch2189 ok good point:) I was strangely disappointed watching this until I read your comment.

[@MvnStn]

I feel as if a lot of scientific discoveries such as this have been well documented long before they are released to the general public. For example, the recent "rediscovery" of Earth's atmosphere extending hundreds of thousands of miles past the Moon. While completely new to me and thousands of others, this is over 30 year old information apparently, and some say they remember when this was announced. We were taught all about NASA and the moon landing and other sub categories of space here and there in school, but this was definitely never mentioned. Kind of a big detail to exclude, no? But, what do I know? I'm just another 97%er, on my own singular quest to uncover what IS. Cheers.

[@alohathaxted]

And its behind a paywall.

[@ThankYouESM]

Over a decade ago, was there not a new type printer that can produce the full spectrum of colors on regular paper without any ink or of the sort, but from micro-precision lasers as inspired by the Blue Morpho Butterflies?

[@Personnenenparle]

Isnt total internal reflexion actually what makes rainbow? How is it any different?

[@aie007]

Refraction (bending of light) and scattering of light help in the formation of rainbow. But in case of TIR (Total Internal Reflection), the incident ray gets reflected inside the first medium rather than getting refracted into the next medium. Rainbows involve two mediums - air and water and the light incident from the sun gets refracted to form a spectrum or band of colours like in the case of prism.
Hope it helps.

Pretty, but the science is pretty common-sense stuff, no offense. I saw MIT had a UA-cam channel and I expected, I dunno, time-travel or something lol
