Inflating soap bubble reveals surprising fluid dynamics

An inflating soap bubble captured in extreme detail has revealed how its chaotic interior follows surprisingly predictable patterns. Saptarshi Basu at the Indian Institute of Science in Bengaluru and his colleagues blew soap bubbles with air containing droplets of olive oil. They then shined a laser sheet through the bubbles which lit up the olive oil particles, allowing them to record the flow of air with a high-speed camera.
Basu and his team found that, contrary to the chaotic processes that they were expecting, the bubble’s characteristics as it inflated followed predictable patterns. “Surprisingly, we found that there are a lot of scaling laws that you can establish, which takes into account how this bubble grows and how the vortices are formed,” says Basu. “Regardless of what kind of pressure you are inflating it with and how the bubble is actually expanding, there are some universal characteristics of the flow field inside.”
These characteristics, such as the amount of vortices present in a bubble that has been inflated for a certain amount of time, could be used to help understand how the fluid moves inside cells that grow and stretch during movement, such as heart cells that pump fluid around the body, says Basu.

Predictable is surprising?

[@heliogenesi]

The fact that it is predictable can be very surprising for sure, why not?

[@wordreet]

Thing is though, cells aren’t exactly empty like a bubble. They’ll be plenty of cell forming malarkey in there, not to mention my bank balance!

[@FlavourFool]

@@heliogenesi Well it makes me think that if an expected result surprises someone, then any result is surprising. Do you see what I mean?

[@FlavourFool]

@@heliogenesi I suppose I do use the phrase myself, but usually to insult a bad film, or complain about the behaviour of the human race...

[@heliogenesi]

@@FlavourFool it wasn't an expected result, they were not expecting a predictable behaviour so they were surprised

Please use “shone” rather than shined. 🤔👍

That's what I thought too but Google disagrees.

@@chrisarmstrong8198 Heh, google is full of schoolboy errors. 😁 I'd go with the OED personally.

The creation is mind blowing. Just think that there is a high possiblity all thisis by design. Something very mysterious but there are patterns that do show there is a designer as well as an a artist because the best art is found in nature. for me anyway that is more intelligent than all of mankind put together that has been and ever will be. How amazing that we all exist to be here. Stop and think about it. Science cannot be without reality. Science just examines and tries to understand someones else work Whose work I do not know.

[@Devious_Dave]

"Whose work I do not know." - do you mean you don't know the work itself or you don't know who 'did' the work? And "Science cannot be without reality" is akin to a pointless tautology.

[@thegroove2000]

Without reality there can be no science. A fact so not pointless. I was pointing you that on the balance of probabilities there is something behind this all, a creator or creators but I do not know what it is as. Is that an issue for you?

[@thegroove2000]

@@Devious_Dave There is not the slightest evidence that something may arise out of nothing. The universe's and nature's intricacies, which are necessary for everything to function as it does, are not the result of chance. Everything is put together. Now for an experiment. Make a particle out of nothing at all. genuinely make anything out of nothing.
