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!

@EwoutterHaar 5 лет назад

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 5 лет назад

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!

@gutspraygore 5 лет назад

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.

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.

@krisweinschenker598 Год назад

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😏

@jjfoerch 5 лет назад

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 :-)

@CorrectGrammar04 5 лет назад

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.

@kwanarchive 5 лет назад

@MegaFonebone 5 лет назад

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?
