That bacterium at 7:20 was I think the biggest one we found. They create giants before cell division and mesmerizing to watch!
-James
Thank you! Also, very interesting video! 😊
Hello! I have a question about the Spirochaete at 7:20, is that a chain of daughter Spirochaetes? Thanks a lot for your enlightening videos.
@@someshwari_debi That’s a single individual, not a colony. :)
I was amazed to see just how fast the "tail" was moving in the last clip... while slowed down 500x! 🤯😱
You do a great job capturing great shots for us; thank you!
@@KY_CPA I think it's slowed down to 500% meaning 5x slower.
Microfluidics is a really interesting field. You can get outrageous yield in microrreactors, but the mechanics of micro pipes are something else.
Are those outrageous yields at small scales how life is able to do anything? Most biological reactors seem pretty small to me.
@@abramthiessen8749 Life pretty much cheats having access to enzymes.
Ah yes when Reynold's number is
@@Kastor774 life cheats getting access to enzymes. That sounds really cool to me. Can you explain further please ?
@@ayushupadhyay801 In our scale, in order to speed up chemical reactions we use catalysts. Thing is, that even now, we're not absolutely sure how they work, we just make up some crap about activation energy.
Life uses enzymes that are so specific that they can cleave and merge molecules pinpoint, that's the point we want to reach with nanotechnology.
7:57 little elefant spirochete
Oo! Seeing the slowed down footage made me think, you guys could set up a proper slow motion camera to look at microbes with flagella! It would be really cool to see those tiny little hairs moving in a more perceptible way in really high resolution and framerate.
the most soothing voice on youtube.
Narration worthy of a major award on its own 🙂
@2:15 so cute watching it walk upside down to the macroscope.
it’s goodyou’re the brother with the cool youtube channel & not the one that got bullied off tumblr
Subscribed. This is so hypnotic
Superb 👏👏👏. Thank you 🙏
Fun fact: experiments have shown that humans don't actually swim slower in molasses. Swimmers have been timed swimming through water and high-viscosity liquid, and there was no meaningful difference. It appears that the increased resistance to moving forward is cancelled out by the increased force when you push against it.
2:00 Water Bear :3
wait till i tell my homie whats in that syrupp.
ayo
Thank you for making it a broad explanation I am kinda dense
Thank You!
I know all about this without even seeing any of the video. I have known for a long time that this is absolutely true --- that when you're as small as an insect like an ant, for example, it throws everything off not only in obvious connection with the relative sizes of objects like safety pins and computer keyboard keys, but it also throws off the whole issue of the viscosity of liquids. There are bugs and insects, including but not limited to mosquitos, that can walk on water because to us water is so liquid and so thin, while to them water is like molasses. By the way, I also know that the microcosmic world is very different in that even smooth objects like ballpoint pen heads are randomly ridged with canyon-like depressions. And water is a ten-thousand-mile lake of sand on which objects like lead balls would float and bob up and down to the movement of sandy waves produced by hundred-mile-high kitchen spoons moved by super-large giants. And these floating lead balls would be so big that they would produce gravity of their own which would attract random clumps of sand to its surface which would then stay there for the whole time tiny flecks of the sand would randomly weep into the air...and now on to the video to see how its information compares to what I already know......
Do not show this to Howie Mandel. But seriously that one little puffer fish looking microbe was totally awesome 🐡
Dang that water be t h i c
So screwing around can lead to ... screwing around.
is there a microcosmos full of micro organisms in blood?? or other various liquids other than water?
Well, I dunno about blood but our guts (and pretty much every animal's) is an entire microcosmos of its own
Oh yes, blood is full of microogranisms, though usually just your own things like white cells etc. If you get something else, you probably have problem.
you can check one of my videos, it will answer your question what's in blood :)
6:22
When you have a density less than 1 in WATER lol.
3:55 ah yes, not very far in the slightest...

Fluid mechanics is cool as long as you don't actually do any math.
So true
Then it becomes cooler (but your head explodes).
You will oneday realize you need maths.
It's cool with the math.
Maths is cool as long as you don't do any fluid mechanics.

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.
So butterfly stroke then
@@juniormynos9457 Butterfly still has a recovery...
in the case of spiraling bacteria, since the viscosity is so dominant, could their motion be considered more similar to a screw pulling itself into wood than to propulsion?
@chu Harry That only works along the surface of a fluid

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

@@wongelfski4681 Your comment is a case study in poetic irony.
@@ansemvanverte This is just my layman's guess, but I think what we see in the slide is not indicative of the day-to-day lives of tardigrades. I'm thinking that they usually have more stuff to hold onto.

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!
i keep reading comments like this on 10-30 minute videos of all kinds of different topics "i studied this for 10 years and this video sums it up better than i learned in 3 years of studying" and other versions of this comment .....
.... seriously makes me wonder how much academic studies actually is worth ....
@@thekito4623 l'm not quite sure mechanical engineering would be generally classified as 'academic'.
It's a practical qualification,like electrical engineering (in which my father is qualified and which he always said was a longer,more complex field of study than mechanical)
They both compare more to architecture, or training as a doctor or dentist.
Academic qualifications require writing a thesis,research into new areas of study,they are PHD's, or maybe MA's .
They are about learning what is already known about a subject,then trying to find out more about it though personal research and experimental work. Basically,expanding what science (or history,archaeology,etc all sciences in their own way)knows.
Mechanical engineers do things like supervise the building of roads,tunnel,power stations.
So yes,it is worth spending the time and effort studying/qualifying so you can do your job competently and safely.
Pays reasonably well too,and most companies give a decent pension 😁
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
There's a really good educational paper about this, actually! I think it's called Life at Low Reynolds Number or something like that, and they mention how important diffusion is for bacteria.
a52Productions reading it now, thanks for the suggestion!
@@a52productions Yes, there is a lot on this subject. This is a very good reference. :-)
The way I perceive it, is that the smaller you get, to a point of being on a scale where atoms, both positive and negative attract other atoms to each or repel each other which in turn, has an effect on the environment. In that environment, it would have to be like wading through stirrup because the micrscopic organism would have to be subjected to greater forces of atom attraction/repulsion.
I could be wrong but, that's how I see it, until I can read some proper papers on the subject.
"Fluid dynamics ahead"
Students: *COLLEGE PTSD FLASHBACK.*
Uhhhh ok ok what is B-Bernouli again??
Fluid dynamics is the most difficult, mathematically defined, classical physics subject. From the prevalence of wind tunnels, it's clear that applications of fluid dynamics is still a very much of a "cut and try" science, just as biology and geology are.

All this DIC footage is incredible!!!
Lol no channel is safe from these jokes
Nobody:... Me: “DIC???!?????”
I wish this channel would dig much deeper into the science
And that's why doing miniatures in movies involving water is so hard... water doesn't scale.
That and fireworks. Sink the Bismarck comes to mind.
Same problem doing scale RC aircraft - you always have to enlarge the tail to get it to fly
@@ThisFinalHandle I know you mean the movie, but the song always springs to mind first
1:37 - it looks like flying eggs
This is one of my favourite science concepts. Purcell's paper 'Life at low reynolds number' is absolutely amazing
Yes, even from 1976 it's still good. "The viscosities have a big range but they stop at the same place. I don't understand that." I'm guessing that it's that liquids can change smoothly to gasses. Consider a phase diagram of a liquid/gas. The liquid/gas transition line ENDS at a POINT. At that unique P,T,density, there is no longer a difference between liquids and gasses. I have always found that fascinating. If you have any information about this subject, I will eagerly read your reply. Ed
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
I don’t know why I like this series. It’s just so relaxing to look at.
And listen to!
@@PeterVJaspersFayer Yes. With Hank's ASMR voice!
This was a particularly well explained episode.

Slowed down 500%? Wouldn't slowing something by 100% make it... stop? Do they maybe mean slowed down by 80%?
I was looking for this question. I believe slowing down 100% is stop. 50% is half speed.. slowing down by 500%... I don’t know what this is supposed to mean.
@@theniha Maybe it's negative speed, which will lead us to discover negative energy required to build warp drive! [I wish...]
Just commenting to see the answer
My guess is the intended meaning was slowed down by a factor of five.
A literal but certainly unintended interpretation would be going backwards 4 times as fast the normal forward motion.
Crayfish walk forward slowly. If they are startled they rapidly fold up their tails in a way that squeezes out a jet of water propelling them backwards very quickly. If we use the convention that their typical walking speed is 100%, and slowing down by 100% is stopping, slowing down 200% would be walking backwards, a crayfish escape maneuver would be slowing down by 2000%.
@@theniha conversion of terms:
20% speed
=500% slowed down.
=500% time take
=[Some say that is 400% more slow or some addition, but this is confusing when not really a quantity]
Different thing, he did a percent of an action, a function. Not a percent of a property.
Oh, that smooth, buttery 4k60fps... thank you so much!
Realizing how big protist cells are when you see that one trying to eat a tardigrade which, if I recall correctly, are comprised of about 2000 cells and here this single-celled protist is larger than the tardigrade!

Imagining syphilis as a tiny corkscrew worming its way through my blood somehow made the concept of syphilis worse.
Currently fighting Lyme disease so these spirochete images were especially interesting to me ! Thanks !
rotifers be like [kirby inhaling sound]
Perhaps the flagella are so thin and tiny, they more easily pass through water, literally passing in-between water molecules.
Then they wouldnt generate thrust. Also they cant be that small. For nanoscale motors check out kinesins and dyenins.

The Reynolds Number
Have you read this?
Yes. Just read a book about fluid dynamics that has no math in it. The Reynolds number is very important. It's like learning that all life is made of cells: very fundamental.
i can't believe liquid dynamics uses the dennis system
So... Fluidic Space from Voyager, got it

Yay!

this is a wonderful video and i super support the project! but, the speaker has a snarky way of speaking i find off-putting that slows me down on wanting to watch more. fwiw.
Reynold's Number....I have just learned something!!! Never too old!.......
Love the content, it would be great to see some creatures from sea water, there is whole other world out there :)
Good idea!
Yeah thumbs up!!!
Yeah definitely 🤘🏻
What do you mean by "Slowed down 500%"? That's not correct. "Slowed down 80%" or "20% of actual speed" would be much better.
This in my opinion would lend itself well to a superhero with the proportional powers of a human-sized microbe.
Imagine a guy who looks like an Amoeba just casual walking through a wall or ignoring a moderate ocean current.
I love that the Lockpicking Lawyer has microbiology as another interest besides lockpicking, youtubing and lawyering.

It’s weird hearing Hank Green talk quietly and calmly. He’s much louder in SciShow
Hamilton has messed me up. Now whenever I hear “Reynolds” I immediately think Reynolds Pamphlet.
Moving fast in molasses? Think of driving on tarmac Vs. In mud. Tarmac is more viscous than mud, and a car wheel can make contact with it and make use of traction. Tarmac doesn't move very fast compared to its neighboring layers, and friction is available to allow a driver to propel forward.
Try to drive through mud, and the more fluid layers of mud slip against each other, so no matter how much a tire sticks to the surface of mud, the layers of mud underneath undermine any progress of the tire because they do not cohere to the layers of mud bellow them.
This is why graphite -made of sheets of carbon atoms -is used as a lubricant: one sheet of carbon atoms easily breaks away from the sheet next to it.
Now we can see there’s a real incentive for an eukaryotic cell to invite a mitochondria at beginning of a life.
I need a collab video between JtM, Kurzgesagt, and CPG Grey...
Very interesting. Thank you.
What is the organism around 5:30. I saw one of those just today under my microscope.
So does the Reynolds Number also explain why an ant falling from a great height is not injured, but a human is?
The power of viscosity is growing until you can move only with the water...law of physic.
I used to go swimming. And I assure you that after a few pools, you really start to feel that water is actually quite a thick and hard to move in thing
Could the viscosity of honey account for some of its antiseptic properties then? If water is thick when you're small, honey must be like tar to microbes.
Did you know if you say Reynolds's Number three times in a row a wild Destin Sandlin appears?
sir... we need information of Nitrification bacteria activity...
please... 🙏🙏🙏
Question: why all of these kind of videos are in water? Why dont you record microscopic life In earth ?
So a thought came to mind in the worst of infection and poor health would (if possible through scientific studies and testing) being frozen for a period eliminate or even subdue some of the worst viral and bacterial infection we are otherwise unable to change 🧐 just a wild thought prob nothing
You scared a microorganism. That is crazy such a simple organism experiences fear.
Hello Sir.is this all available in hindi also as I cant understand english so much.one more thing i want to ask that what type of microscope have u used for capturing all this.which model.i m also crazy about this.
If they only move a tenth of a diametre of a hydrogen atom, then technically aren't they not moving at all? Sounds like they wouldn't even be able to displace the water that's in their way.
