Droplets in Motion (feat. Hannah Fry) - Objectivity 192

[@lowercaserho]

So when do we get a video of Dr. Fry talking fluid dynamics and droplet deformation on Sixty Symbols? Come on, Brady, make it happen for us!

[@purduesimlab6412]

I love Dr. Fry's enthusiasm! I want more episodes of people looking at the historical thing they earned their Ph.D in or researched upon.

[@francismoore3352]

You could have new Ph.D students talking about it!

[@purduesimlab6412]

Yasss! That's a wonderful idea. Please make it happen Objectivity. Alternatively, someone please start another channel that does this.

[@N.I.R.A.T.I.A.S.]

2:25 "Professor Osborne Reynolds is a big deal in the fluids world." Yeah, I guess he ... made quite a splash. I'll show myself out.

[@MegaBanne]

Why just the two-dimensional?

[@rfldss89]

Fry is undoubtedly my favourite thought leader. Also, can we all just stop for a moment and appreciate how much we're all in awe about pictures of milk splashes?

[@SergeantSphynx]

I didn't realize that Dr. Fry got her PhD covering an aspect of fluid dynamics, an area that I am specializing in in Mechanical Engineering. Also, cool to see some early work on the field. Awesome video.

The quality of the photos is astonishing.

[@EwoutterHaar]

Very appropriate subject matter for a channel called "Objectivity". You all should check out the prologue to the book "Objectivity" by Lorraine Daston and Peter Galison (2007), which describes how Worthington transitioned from drawings of his visual experience to "objective" photographs. While the photographs reveal a much more particular or even chaotic world, the drawings may have been a better representation of the symmetric essence of the phenomena ("true to nature", as Daston and Galison write).

[@MegaFonebone]

Ewout ter Haar A very interesting question. What is more “objective", a single snapshot in time, or a drawing that captures the time-averaged perfect symmetries? Perhaps both equally, but in different ways. Thanks for the great and very relevant comment!

[@alicewyan]

I'll never not click on a video featuring both Keith and Hannah! 😄

[@zhubajie6940]

Fascinating. In boiling and condensation, this is very important in heat and fluid transfer. More efficient air conditioners, jets, rocket engines, solar collectors, wings surfaces in rain this science will continue to lead into many applications as we continue to study this phenomenon and here were the first baby steps.

[@gutspraygore]

Just wanted to mention how much I appreciate Keith Moore in the videos. His contextual understanding of the subjects are what elevate these videos from interesting to fascinating. Thanks, Keith! Also, it's always a treat to see Hannah Fry. I just recently read Storm in a Teacup by Helen Czerski and it reminded me of Hannah (I dunno why), but I'm surprised to find that she is also into the dynamics of fluids. Thanks for making these videos, Brady.

The cover on the last book is pretty cool.

[@akk709]

Keith and Hannah in first video for the year ... 2019 has started well

[@krisweinschenker598]

Reynolds number is a big deal in fluid mechanics, because it's dimensionless, and thus very helpful in modeling. I did my senior college thesis on Aerobraking around Mars using a dimensionless factor that accounted for the difference between Newtonian and Continuum flow(I forget the name, however) Isn't that kind of ironic😏

[@kujmous]

This science really is beautiful.

[@unvergebeneid]

Obviously the highlight of Hannah's thesis are the figures in section 2.2.: "Air flow over a surface mounted semicircle." Spectacular colours!

His work is very important after all, especially in cardiology and such.

[@jjfoerch]

Hi Brady - I was thinking about your ongoing quest to find artifacts in the Royal Society collection that have good pictures for sake of visual interest on youtube, and had an idea. Why not, instead of having the videos so closely focused on a handful of artifacts, use the artifacts more as a jumping-off point to delve into a broader topic, and maybe discuss the history of the topic beginning with the artifact, tracing it through to today. Then bring in visuals from anywhere to tell that story. Anyway, I love all you do, so keep up the good work, cheers :-)

[@SavepointCafe]

I remember studying Venturi tubes in Instrumentation, where there was a lot of fluid dynamics discussion going on. Really cool to see early work about it here!

[@yesthatsam]

I noticed the last books use centimeters units, was it already common in 1908 not to use imperial system at the Royal Society ?

[@CorrectGrammar04]

They don’t wear gloves when handling most paper. It’s very delicate, and so they risk lesser possible damage from exposure to oils from skin in favour of not tearing the documents.

[@SapientPearwood]

Wait hannah fry is a fluid dynamicist?... why did she defect to math???

[@riverbender9898]

That seems counter-intuitive...What about the definite degradation that oil, dirt, perspiration certainly inflict?

[@douro20]

@@riverbender9898 The reason is that there is a risk of tearing the pages.

[@kwanarchive]

@@riverbender9898Also, I think light does more damage than oil, dirt or perspiration.

[@MegaFonebone]

I imagine it depends on the age of the document and the composition of the pages. They probably weigh the risks of different handling methods for each different piece. They must use gloves for some - isn’t a gloved hand the icon for the channel?
