The puzzling physics of sand
Sand, is it a solid or a liquid? ⏳ How come it flows, but we can walk on it? In this last video from The Lutetium Project, we explore the puzzling physics of sand!

Very nice, I think microfluidics is the future. Imagine a bio-chip that reads off your current health status, that would be very cool.
so beautiful art and physics, easily subscribed <3 Thanks for keep inspiring us
Thank you for the subtitles, it is much appreciated.
It will become fluid exchange circuits.
what is this witchcraft
wow. a pristine example of visual arts at its finest.
this video is so cool
It is Schrodinger's bi Billi(Cat)
Can someone tell me which is the song’s name please? that is very beautiful
You deserve more subscribers
God of physics is here 😍
Good en well explained thanks
I'm tripping balls great video
Fantastic video!!!
Loved it, thanks.
approx.. how much it will cost to fabricate this type of chips.
Great video ! Very clear and concise, and beautiful visuals and animations.
This is absolutely adorable!
im watching this on an LED display
Soothing
Very exciting work. Can you help connect with the lab
Microfluidics is so interesting. But I'm worried about the accuracies and precisions when mixing liquids. What's the progress here?
Really great video!! Going to use this as my go to when explaining to others.
Thank you for the info.
Amazing
Very very well explained thank you!
4:51 for a reminder of your mortality
This video is incredibly clear and concise. Thank you!
Do you screw with sound because you're a nut? up down up down
Hello to your young team ! Very nice channel and very clean and educational content. I'm discovering it too late :) I have a question to ask you about microfluidics, which I've been interested in recently. For the moment, I think that these "lab on a chip" are mainly used to replace the Petri dishes of the laboratories, a kind of culture system more close to the living conditions and thus more reliable to monitor the evolution of a drug in the body. But could we make real chips, real electronic circuits with it ? So far, I have the impression that it is a plumbing system on a micrometer scale, but if this plumbing were crossed by a electronically conductive material, wouldn't we have an electronic "chip" ? For example, couldn't we also make a MEA (Multi Electrode Array) with microfluidics ? If you have any information on this, I would be very interested. Thanks again for your hard work :)
Simply amazing !!!👌👌👌
Hi I am 40 and I am falling in love with this field of science. Is it possible for me to work in this field?
How does this not visually explain the existence of matter? No, go ahead. Change my mind. I'll wait.
If you are last year PhD student or PostDoc and you discover something unexpected and cool outside your Research project, DO NOT share it with your Supervisor. Keep it for your self and built your own research line from there 😁.
4:55 Not sure implying I’m going to disappear or my defects will disappear. Both are true, I guess.
Such a good explanation. Sad that you'll stopped uploading :(
please....MORE!!! :) (im new here....)
could you teach us how to design a microfluidic chip using softwares such as autocad?
💖valubal inform mam 💖
Great explanation of the basics of surface tension and some cool visuals! Good sci com guys! Looking forward to all the ways you use it in microfluidics!
Wonderful work! Helps understand a complex concept in a simple, intriguing way.
beautiful and amazing , frantic
C'est une approche très théorique et universitaire des cristaux liquides, un petit show des différentes interfaces des années 60, utilisant les cristaux liquides aurais apporté une petite approche ingénieur au sujet. Surtout que niveau ingé lcd avant le pixel c'est très "cru" très visuel comme technologie. C'est plus simple que nos lcd d'aujourd'hui on peu les décortiquer et apprendre comment l'ingénieur à adapter les cristaux liquides sans notre tendance à miniaturiser. Je critique parceque la vidéo est quasiment parfaite c'est incroyable. Trop trop fort la qualité, la maîtrise du sujet, tout est carré. C'est vraiment de la vidéo de qualité félicitations !
absolutely incredible how much i learned from this low-key video. everybody should see this. i'm talking core curriculum.
amazing to watch
How do we get 256 different shades of color on a subpixel ? Does the liquid crystal change the intensity of the light that passes through aswell ?
<3
Amazing!
if we increase the flow rate in a microfluidic channel, wont we get a turbulent flow at some point?
Can you recommend a Programm for the Design of This chip?
