thank you !

[@thierrymoutard-martin12]

These videos are still today invaluable teaching tools. Thank you for uploading.

[@pms87cooldude]

before praising about this video i would like to thank barry for doing such a generous job.this video helped me and also will help any one who has the interest to learn such things.Even though this is filmed before decades,it gave me a clear perception..i had also gone through other videos uploaded by u.Pls consider this post as expression of my gratitude.

OMG At 2:00 minutes he talks while his attention is turned to the blackboard! How genuinely humble. What a cool technique! You don't see this on a Vsauce video ever.

Lecture notes are available on the National Committee for Fluid Mechanics Films web page hosted by MIT.

If my teacher were really interested on giving us a real learning they would have done something like this to give clear examples

[@imegatrone]

after i watched this video, my insight is very open because the video is very good to give information was created about half a century ago to explain fluid mechanics in an accessible way for undergraduate engineering and physics students

[@rwatson8]

I think this is supposed to be supplemental to an in-person curriculum. Few teachers then or now would be able to get their hands on so many of these materials and experiments all in one place, so they use the video to inspire the kids (and you and me!) and explain in detail afterwards.

[@allenhoffman7701]

What a great video. I did my PhD thesis (1970) on the climbing effect in non-Newtonian fluids and how it was related to the material properties of the fluid at the University of Colorado. Allen Hoffman

[@Tadesan]

This should have been done at the college of textiles at NC State. I'm learning that my school wasn't as good as they told me it was...

[@lekunberriko1]

2:43 Please, could you tell me what polymer solution is it?

[@alexbk25]

Thanks Barry for uploading this Oldscool Awesome material!

[@xaviersim9697]

Hi everyone, assuming a shear stress mode, what is the moving plate and stationary plate?

[@sauravrajsriwastav428]

because of the volumetric flow rate Q, which can be expressed independently of any constitutive equation as follows (

[@manikantach7900]

Can you make a video on rheologlcal properties of fluids

[@rushabhyeshwante]

Wonderful explanation.

[@textexingworth2798]

Came here for structural geology and it works just as well in explaining my field. Thanks!

[@lovecraft22]

I'm watching these videos and they are interesting. The only problem I see with them is that even though the experiments look nice, nobody gives any explanation on why a certain behaviour is achieved… Is this the way of teaching in the US or is it just these videos?

[@stock9291]

These videos are not intended for that or tests, but rather give you an insight on the nature of fluids through series of experiments.

[@trystion18]

does anyone know where you can get notes on this lecture or a manual explaining the apparatus used around 8:20? I'm trying to do it for a physics final lab project and wanted some more information (articles, journal entries, lab manuals, etc.)

Very cool video.❤

[@yohannismitiku2010]

Perfect tutorial. Thanks

[@saddu93]

wow..this makes physics really easy..

[@sqp1956]

excellent, I will be using this video to better explain fluid rheology behaviour to my fellow drilling new grads in future training sessions.

[@basseybassey6834]

lovely and useful

[@lu23181]

Muy interesante video, trata temas muy importantes como lo que son los fluidos newtonianos, elasticidad y la viscosidad de ciertos fluidos y además menciona el significado de la reología la cual es el estudio de la relación entre la fuerza y la deformación en medios. También muestra algunos experimentos bastantes interesantes referentes al comportamiento de algunos fluidos cuando se les someten a ciertas condiciones y como identificar las características que tienen algunos fluidos como su elasticidad o su viscosidad así también como su tención.

I'm watching anime and also a vid about rheology that recorded 70 years ago. Life is strange guys
