My fiancée calls this show “Sleepy time Bacteria”
I showed this to a friend who had trouble sleeping, and he accused me of surreptitiously teaching him more about biology.
Microbedtime for me :D
Carl Sagan if he over dosed on cough syrup.
😐 Hmmm. That's what I call it. Suspicious.
Get one of the Video Speed Controller apps. Run Microcosmos at 150% speed. Also, turn your volume up way loud.
Hank: “This is the last episode”
Me: *is dying*
Hank: “...of the first season”
Me: “OMG THANK GOD”
The perfect comment, I'm nominating it for a Webby.
Me too lol
Right???
My heart skipped a beat.
same
I love every time you get a momentary view of the 3-D shape of these organisms. They become so much more real in those moments...
yeah. it is about those waves & vibrations in the world of phenomena!
Now I want to see their 4-D shapes.
0:41 "the organism seems to be lit".
My kind of organism
bruh, as if looking at these vids aren't trippy enough
👌💯
Yep, y'could watch them on weed & zone out.
Or project them on the inner surface of a floatation tank, while using ketamine, for the maximum effect.
@@_ninthRing_ yeah 😎
I made 420th like hahah
As someone that works with microscopy on a daily basis, this was wonderfully explained! Your science communication chops are showing!
second this
Except where they said "light doesn't enter your eyes". That was really stupid 😂
Could you recommend a decent microscope to invest in which can also take picture/video Or hold a DSLR? Thank you
No
I’m looking at going into the biological field, either for something related to microbio or for ecology and evolutionary biology - if you have time, do you know a good school that i could apply to? I was gonna look at a&m, but i’m not sure how everything is looked upon in the scientific world as I’m only a high schooler lol
i really like darkfield microscopy
It looks like looking into the sea, underwater. How beautiful.
Even though there isn't just one answer to what microbes look like, darkfield seems to me to be most similar to how things look on our scale.
Same, I need more
I like darkfield best overall, but I like the rainbow crystals of polarized microscopy too. I wonder if you could combine the two?
Darkfield microscope is very hard to calibrate
I’m not used to Hank sounding so calm. Usually in sci-show he’s so energetic. I didn’t recognise his voice at first. Great series by the way.
I completely lost focus on the narration when that living mikado set came on screen at 3:43.
Would like to hear more about that one.
Living mikado lol
Yeah same here. I was like "wtf is even that?"
It’s called a sick stick
Same. I had no idea what I was looking at, it seemed too amazing to be real.
The way they slide past each other. So cool.
It's Bacillaria, a kind of diatom!
The species displayed in each clip are listed in the top left corner, for easy googling. :)
From season 2, I think we can all expect more bikini models, car chases, and explosions than season 1.
*pictures a tardigrade in a bikini*
Explosions in biodiversity?
@@evilsharkey8954 picturing something like that is beyond the laws of the universe, please stop.
Huh! Let's see what we can!
Bacteria in bikini is being chased by a macrophage. After being inevitably eaten, bacteria fuses with vacuole in side macrophage and explodes.
4:58 - *Hey, you caught my good side!*
How do you write comments?!?!
Love you rotifer
Based Rotifer
@@ourochroma 💚
Sup my boi?
The best present I got as a child was an old brass and glass microscope. When I first looked at a drop of apparently clear water from an outside bucket and saw a whole mini universe of moving creatures I was amazed. Your channel reignited that fascination. The images are amazing and the narration is perfect, both informative and witty. Thank you to all involved. ❤️
A question for next season: What senses do these microbes have and can they feel the bright light passing through them?
Simon Clarkstone, some of them sure can! It makes it hard to observe them when they keep running away, but I’d run away, too, if someone kept focusing a bright light on me!
Many motile microbes have “eye” cells/organelles (photoreceptive cells/organelles, like those two dots on the tardigrade face at 8:25), so yep some can experience the light. For the response it vary between microorganisms, some try to get away from it, while some move closer to it. Also if we have to say objectively what would they “feel” in their own tiny umwelt, we don’t know for sure.. since we don’t have the necessary “senses” to experience them ._.
I expected some microbes would have a sense for ambient light, like photosynthetic ones. There might be some interesting specific species to show off too, e.g. with different-looking photosensitive organelles or colours or strange behaviours.
Honestly im curious as to how they 'perceive' anything at all - do they have a central nervous system that can collate and process such information, or some decentralised one?
YYE Starry I’m only a first year Biology student so correct me if I’m wrong, but most microorganisms “perceive” things through chemical signals from their surroundings. Their cell membranes interpret the signals through specific receptors, and the cell reacts accordingly.
Man, what a channel you guys have started. I found the first episode on reddit when it aired. Since then everytime you guys upload, everything gets put on hold for me to watch it. Just amazing content. Content that has given me a complete new perspective on the world and life. I've always been told about the microcosmos in school but it really hasn't ever clicked like it has watching your video's. Thank you and keep up the great work!
Man, what blows my mind is a majority of microbes are just... Living bubbles filled with smaller bubbles.
They are much more complex than that. The complexity comes from what you can’t see with an optical microscope. In reality, these microscopic organisms have hundreds of chemical moving parts!
Many are strangely-shaped bubbles, like clown animal balloons.
@@andrewanderson8803I don't think they needed that explained lol its pretty much what they were saying... to us they appear to be small bubbles but they are amazing. Their seemingly small bubble bodies hold so much complexity.
The polarized light shots are always my favourite. Like you said, Hank, it's like looking into an entire cosmos wrapped up in a tiny little microbe. The world is not only stranger than we suppose, but stranger than we can suppose. I love this channel, please keep up the good work!
3:08 Woah.. is that a colony of single-celled organisms acting like a muscle fiber?
I think so. This is fuckin cool.
I believe that's bacillaria. This channel has a video on it.
Yeah, whatever it turns out to be I want more because omg was that cool 🤣
Such a profound way of seeing the world, gained from watching the beautiful critters in the microcosmos. That's Hank Green for you. What a wonderful episode to end a season. Thank you, and see you in the next one guys ❤
Hank: ..."and then, we will be back..."
Me: starts to breathe again!!😅
YES! COME BACK...
This topic about what we see and what things really look like, allways blows my mind.
I love you Hank Green. Let's go get a pizza when the pandemics over.
Hey I'm subbed to your channel!! :)
Still going on, we are entering the last third of this apocalyptic test run.
10 months later and my country is still in a national lockdown
"gorgeous bastards" lolll
Love your work!
"This will be our last episode.."
*Heart stops*
"..of our first season"
*Insane relief*
I live for these videos. Every monday I wait for them to drop and watch them as soon as I can. These are the only videos where I sit down for the whole duration and watch all the way through. Thank you.
As someone who spent five years staring down a microscope in the 1960s. I love this. I initially worked as a histology technician, then moved to bacteriology, specialising in acid-fast organisms and then mycoplasmata. sadly we used none of these techniques. Pretty much everything was stained.
The complex Kaleidoscope of colors and detail you can capture filming these microbes is honestly just amazing.
... a glowing tardigrade ... pretty please ???
Edit : i am happy . I am satisfied . I am no longer sick , my life is completed .
Standing ovation for the first season. Thank you for this channel, it is truly wonderful. I look forward to season two and all of its wonderful and tiny guest stars.
Is it weird that I fall asleep to these videos now?
I'm glad I found this channel. Chill learning.
Yo you should show more of them under polarized light, it looks really cool!
This makes me feel like it's not just the microcosmos that isn't what we actually think it looks like but the same applies to our universe. There might be hidden secrets that go beyond our visible range in the light spectrum. This is a wonderful episode showing us the intricacies of how we perceive things vs. what they actually are. Thanks a lot Hank for a wonderful season. Can't wait to Learn more
Check out "Plato's Cave". It's a very profound philosophical demonstration that will change your life, once you start understanding it.
@@rickbailey7183 Thanks a lot for the suggestion. It was really interesting. Reminded me of the theory where the entire universe is a hologram and the book called the Grand design by Stephen Hawking where in one of the chapters he discusses our perception of the universe as that of a fish through a glass bowl.
I have always had an interest in microbiology...watching teeny things moving around silently performing mysterious functions just seems so fascinating in a way I couldnt explain to others. For me it is the same as staring into a fire or looking into the sky at night...an inner depth which may explain anything or maybe nothing. Hehe although I have to admit it is also a handy interest for when you want to wind down.
Ahhhh, this whole episode is such eye candy !
I had my own personal poinant moment of perspective awareness when the outro card appeared, and I realized I had watched this entire episode upside-down without noticing. Reminded me that my 'up' is left, right, back or front to most of the organisms shown.
*Season 2 let's GO!*
Yes! Looking forward!!
You seem awfully fascinating, I hope we get to see more of you, too! 😃
4:21
*Yes.........a moss piglet!........you made my day!*
What a wonderful first season, what a lovely way to bring it to a close...and it's going to be mildly like torture to wait for the next season! I am so very glad you won't leave us quite yet. This channel has been such a pleasure to watch and to listen to; I've learned a lot and I've also treasured each little slice of meditative peace every week. I don't know which I value more, right now, the knowledge or the chance to just breathe and exist. The synergy of image and voice and music makes for an experience that's very zen.
Thank you for taking us all on this Journey with you. I love this channel, Keep up the great work and enjoy your break. I'll have to binge watch all the old episodes til you're back. Lol! :)
Thank you, I greatly enjoyed this season. I'm looking forward to the next.
These videos are so informative, and really calming too
Yeah! And soberingly dry yet beautifully poetic 🥰 and super entertaining! But I guess with this voice and diction, I would be happy if he read from a phone book or something like that 🤭
The commentary along with Hank's voice is a perfect match. Easy to listen to. Also, a HUGE THANKS to the writers of this series. You all deserve an award. This is what needs to be used in our schools.
This has been my most favorite episode so far! It answers so many questions I've had as I've watched the whole season. It leaves me thinking about Ed Yong's book, An Immense World -- and how very limited our perspective on the world is with just our view of the visible spectrum. It also makes me question the use of the term crystal as it so pertains to its perception using visible light. Finally, seeing these explanations of the types of microscopy used has me wanting to see more of the environment and practice of the microscopist and setting it up.
An absolutely fascinating series that makes me want to get myself a microscope again!
JttM was my best present of 2019. I look forwards to seeing future seasons! Many thanks!
Thank you for this wonderful channel! I look forward to my 10ish minutes of Zen with Hank every week. Have a great week off and we'll see you soon!
Thank you so much for making this series! I find it utterly entrancing. In the last week or so I've been inspired to dig out my (very) old compound microscope which was discarded from a lab and given to me when I was a kid. I cleaned it up, fitted a much brighter LED light source and have since been having an incredible time discovering many of the familiar faces from this series. I cannot express the excitement and wonder at seeing a rotifer, a tardigrade or a vorticella for the first time, but surely you will know it. Please keep making this series!
Please, more like these about the techniques. Riveting, and always awesome!
Thank You to you and the team that put these together for us and Thank You as well to the patrons that funded this for those of us that could not.
This is easily one of the best TH-cam channels in its history. Highly sophisticated and educational, yet simple and beautiful. All that being made by individual creators, not some company.
I'm truly grateful for every episode I see, dumbstruck every time. You're making this website's (and medium in general) history.
I just found this channel and it's absolutely brilliant! It is definitely my new favorite youtube channel. I plan to methodically view all of the uploads.
Thank you for the tech instructions. One thing to talk about next season would be to describe more what is known about the organelles we are seeing. What are those fascinating little globules inside our little critters. Some for waste disposal, some for digestion, we’ll you get the idea. Ps. I didn’t see a link to your Patreon account.
man i just love watching this when im super calm its nice and tranquil
I like to see it when I'm not calm, and for the exact reasons why I like to watch them too, when I feel calm 🤭 It's as dope as a good session of mindfulness to me! 🥰
Thankyou for making this series. It's educational, relaxing, aesthetically and aurally pleasing. Enjoy your break. Looking forward to series 2.
Wow guys, this production rocks. One of the best on the inter-tubes. 👍
I found your channel via this episode. I think if this one was right at the top of the "Season 1" Playlist list, it might help viewers appreciate the series more from the start. 🧐
Starting with this before starting the actual series, I think, helper me appreciate the actual story more.
Best voice ever, BTW 👌
This is the best channel on TH-cam!
Hank? Be carfeful, now. I could detect actual emotion and excitement in your voice in this episode...
Thank you guy's so much for these videos. The way in which you present the microcosm is engrossing and I can't get enough. I hope there are many sessions to come!!
It's been wonderful to have you for a whole season! I can't wait to see more into this incredible microcosmos You show us, and explain in such a soothing manner 🥰♥️
I was looking at Diffenbachia idioblasts and raphides yesterday. I feel like one of those phase microscopes would have made my job easier
My next question would be... What sort of visual experience tardigrates had?
Since human eyeballs arent meant for this microcosmos, we probably need "eyes" from that world
Imagining the visual experiences of a tardigrade? Shit man I think you just broke my brain. ...Have you ever read "What Is It Like to Be a Bat?"
Imagining the qualia experienced by a tardigrade... is your red the same as my red?
I guess they can only see different degrees of light to distinguish food from a threat.
I love this channel so much. Thank you for this, James and Hank.
I'm totally fascinated by this! I never studied biology at school, and so never learned to use a microscope. I love watching and learning about micro organisms, so my wife bought me a digital microscope for my birthday. This video explains why I've been so unsuccessful. I'd love a follow up video showing the various setups.
PS- what is that thing at 3:08?! Pretty amazing!
It's labelled if you want to look it up.
@@kuronosan HA! Didn't even notice that on my phone. Cheers!
Spirogyra
It's a sentient venetiian blind.
I really enjoy this series💚🔬
Thanks for explaning all of that Hank. It is truly amazing how those different light fields render clarity & color to all of those interesting microbes. Great work & have a nice week off.................. 👍👍
I so love this channel. Honestly it's probably my favorite. You make learning all this so easy. Wish I had this channel when taking biology in college, it would have made things much easier.
And what a season it was, great content with Hank's soothing voice to embellish it. I love a good meme as much as the next, maybe even more, but i am thankful that some people use TH-cam to share knowledge. I think that was the original idea of the internet... before cute cats got involved.
Broaden your mind - do both microbiology AND cats. Makes for an interesting life. PS - chicks dig it.
@@smartin8247 Like i said, i don't skimp on the memes
2:06 Hes stolen all the candy crush candy and gems
Really love this series. I think this episode in particular could have used a diagram on the side for each of the different lighting techniques so that we can better understand your explanation. Keep up the good work!!!
I really like the ambient background music. It makes the videos even more enjoyable. Thankye for this channel.
I also very much like that narrative voice, very captivating.
Can these techniques be blended? Quickly switching between them and then bringing together selected aspects?
I would love to see an organism as a composite image of all four techniques, possibly enhanced via computation, into a fully realized whole!
also I wondered if you shot with high fps and had a a device quickly move the focus slightly within a defined range, if you could focus stack them into a slower fps film.
@James Niland. Is that a ‘thing’ in another field? It sounds interesting and possible.
@@sachiperez It is in macro photography. People will mount something like a fly and then take a lot of macro photos of it. Between each photo the fly gets moved a very tiny bit, so the focused area is on a slightly different spot. Afterwards the series of photos gets put through a program that combines them into one photo that has all the sharp focus areas of all the separate ones. The process is referred to as focus stacking. Probably some videos about that on youtube.
You should narrate documentaries, you're like an American David Attenborough
This is pretty close.
Hank is indeed a brilliant educator!
He's certainly easy to listen to. But no way near the level of the Attenborough.
I got so excited when it got to the polarized light microscopy. Learning the optics of those types of microscopes was a huge part of my Optical Mineralogy and Igneous and Metamorphic Petrology classes, The labs were tedious but fulfilling since it involved looking at pretty colors and shapes from rock thin sections and learning to recognize the different minerals. For some reason it never occurred to me that this optical method could be useful in microbiology. I learned me a thing today 😃
I LOVE this channel, it's sooo beautiful and informative!!! Thank youuu please don't ever stop posting videos
Season 2. Hell yeah :3
Have a good break, guys!
I love how fractal the universe is. That is, our microcosmos shares similarities to our larger cosmos, out in space. Because as you describe the forms of light we use to see the microcosmos, and how none of them are really THE ONE objective way to understand their existence, I think of nebulas and how we see an interpretation of the light they shine at us. If we were able to travel into distance space toward them, we would not see the colorful plumes of gas and cosmic matter that the Hubble telescope images showed us. Pretty cool to think of the similarities between the two “worlds”.
WOW! I just found this channel and watched the last episode first... Fascinating!
I have the whole first season to watch... great narration with a lot of thought put into it!!!
I think I'll have to get my own microscope out, dust it off, and start viewing some pond water :)
"Ce n'est pas un cilié."
Nice one hahah.
Although shouldn't it say "Ceci" instead of "Ce"?
@@sevsev4078 Yes you're right, that's the only thing that needs to be changed
Ok
noooooooooo!!! come back!!!!!! oh just a week away?! promise??? I'll be waiting then _ like a couch stalker lol
Seriously though, enjoy the break because you deserve it.
Your wording for this subject amazing; made it very easy to understand
The polarized images are so beautiful; more of those ones please!
As usual this is an astonishing video. I think the "questioner" was probably referring to the exterior of microbes. We don't usually see through most macroscopic objects.
This was interesting! Also, the glitterlight (thats what Im gonna call it) is so beautifull !!
I appreciate the more 'natural' tone of voice instead of the more 'theatrical' of other episodes :)
Congrats on a great season, very informative show.
11:46 i almost had a stroke
ahh what a relaxing video
I sometimes watch these for like mindfulness! 🤭
Watching this during quarantine insomnia. Thanks so much for this guys. It’s so soothing and calming during this anxious/sleepless time
Sir, this channel is another level in youtube videos. Thank you for sharing this!
Asmr at 5am, just what I need to sleep.
This voice! You could make a fortune doing mindfulness! 😙
I'd rather he made a fortune doing science myself!
@@edgeeffect quite honestly I already use these videos as a kind of mindfulness 😄 preferable he does what he needs to do and what he wants to do. I just hope that he'll be wanting to do mindfulness thing 😂 Perhaps a bodyscan! 😄
Fascinating. More please. This is for sure one of my favorite channels
Thank you for taking the time and effort to create such an educational channel. Your hard work is appreciated!
So, if we were to blow one of these up to a visible size let’s say “the size of our hand”, would it look like a transparent blob with some green spots?
I think he was suggesting it would not appear transparent due to the size difference.
Rafe Tizer Ah, but due to their small dose the light waves themselves shine through differently when under a microscope?
2:21 kinda looked like this dude projected a pseudopodia doing "the finger"
That microbe was flipping us off 😤
Fantastic program. One of few I actually get excited for when the thumb nail appears in my notifications!
Best video on the channel to my information. Least said, most explained, wonderfully executed.
0:40 I'm "lit from within" if you know what I mean 😉
Brightfield Ciliate
Darkfield Ciliate
Phase-Contrast Ciliate
Polarized Ciliate
The four Ciliates of the apocalypse
Insomnia beware
That should be a spoiler.
Long ago, the four ciliates lived together in harmony...
Light is very weird in microscope. Even in *foldscope,* different light conditions and wavelengths can make the image look differently.
*Microcosmos is so beautiful.*
I love this series so much!! Would you guys be willing to put what microscopy technique you’re using next to the magnification and species identification?
