Fluid mechanics is cool as long as you don't actually do any math.

I am become syrup, topological features of worlds

That bacterium at

The viscosity of the water at that scale is also why flippers/fins aren't seen in the microbial world.

Something interesting about viscous fluids -- when the Reynolds number is low enough, reciprocal (reversible) motion doesn't work. If you try to push yourself forwards with your arms, you'll just pull yourself back when you bring them back up. So microbes have to come up with time-chiral ways of motion, usually ones that involve spirals or alternating patterns and such.

It's not easy swimming smol, just trying to get around is an entire workout!

Wow, I'm a Mechanical Engineer with 11 years experience, took thermofluids, heat transfer, and fluid dynamics - THIS IS THE BEST EXPLANATION OF REYNOLDS' NUMBERS THAT I'VE EVER HEARD!

Microfluidics is a really interesting field. You can get outrageous yield in microrreactors, but the mechanics of micro pipes are something else.

This is all very mind blowing, but my question is: as you get smaller and smaller, at what point does the Brownian motion of the fluid begin to dominate the viscosity? I’m wondering specifically about small molecules floating around inside cells... haha and as long as I’m on the train of thought, would also be interesting to peek inside the internal structure of a thermophile

"Fluid dynamics ahead"

The word Microscosmos hits you very differently when you suddenly realize the absolute minboggling amonts of space the bacteria are working with. It quite literally is another world.. wow

This is one of my favourite science concepts. Purcell's paper 'Life at low reynolds number' is absolutely amazing

I don’t know why I like this series. It’s just so relaxing to look at.

"Sometimes the syrup is water, and sometimes it's you!" 😆

As an aerospace engineer, this is probably my favourite episode so far. I hope you make more videos about microcosmos propulsion!

I was binge watching this channel and now a new video appears. Service 100%
