Can we please get more crash courses in microbio?
like ikr
PLEASE make a full set of Microbiology crash courses I would legit pay money to watch them. The anatomy ones have saved my life.
For one I would like to say that this recording of common information is mostly correct and benificial to the public.
Thanks for including the John Snow "knowing nothing" reference. I was holding my breath for it since you mentioned the name.
And then I read the other comments and see I am in no way original, or as clever as the others, lol.
The work of seeing vestiges in biology… the amino acids into proteins and the varieties of translations of DNA over time and systemic growth… silo easing and interdisciplinary work while acknowledging connections to community. The health, climate and tools.
Great vid
Wait, what? I thought Hooke was the originator of cell theory.
He discovered cells in cork and coined the term, "cell"
Who loves Crash Course History of Science?
The past belongs to the past. Don't dissociate me any further,
Calmly,

Origin of life... Where art thou start to exist? Spontaneous universal development? Not just in our galaxy, but Quantum eons away in space from Earth too on other earth like planets near other galactical solar stars with orbiting planets in sytrivical motion? So what makes life? Wrap that around a theoretical concept or few dozen.
8:35 I don't know, I'd say it's more like a lot has been through his lucky microscope!
What about akşemseddin? He wrote about our ilness because of we cant see so small organisma
what about my boy Virchow?
Why pasture
"Spontaneous Generation" - the precursor of Darwinism.
watcherjohnny Are you referring to abiogenesis?
Of course bacteriology started in GERMany 😉
This GERMan needs a tissue ^^
That's why they are called germs. Not the other way around.
John Snow: Knows something.
Jon Snow: Knows nothing.
One"h" letter can change the ability to know anything or not :D
Aaaaah! U commented before I could 😭😂😂😂😂😂😂💀
@@ercaner_buzbey jokes
I feel like there will be a new interest in microbiology after this coronavirus pandemic is over
Please do a complete course on Microbiology! At least the basics it would really help me out right now.
I love this guy. He makes subjects interesting as he talks so passionately about them
John snows study also observed that the people drinking beer from the local brewery didn’t get sick and that a person who received water from that area was a relevant outlier in the study.
Also, a workers dormitory had no cases because it had its own water supply.
Microbes dominate planet Earth! They are nature’s nano-machines!
We all owe a huge debt to Pasteur and Koch for pioneering the field of microbiology in the mid-1800s.
To be honest, if it weren't them, it would have been someone else.
Nano machines son! They harden in response to physical trauma
please put out more microbiology videos kinda gives me motivation to study.
Dear Hank, the one minute you made me wait for the "John Snow joke" felt like an eternity
Jon Snow? Sounds like there is a whole Extra Credits History series you should watch on that.
If you don't watch it, you'll know nothing!
The minute they mentioned people challenging miasma theory, I knew our boi would show up.
Extra Credits is mentioned? Must be Walpole's fault.
glad someone mentioned it
I love the Extra Credit History vedios.
I Loeb this channel
Alton Brown presents Pasteur as a huge hero, and I have to agree.
John Snow seemed to know a whole lot, ironically.
I can’t believe that you didn’t mention Edward Jenner!!!
The guy who changed sex?
Or for that matter Antonie van Leeuwenhoek. He basically invented the microscope and was the first microbiologist thanks to his invention.
Although both Jenner and Leeuwenhoek played a role in the story told here, I don't mind that they got left out.
While Jenner did come up with the first vaccine, I don't recall him being involved in germ theory that much (but maybe I'm wrong about that). In my opinion he definitely paved the way for Pasteur to develop new ways to vaccinate but not to prove germ theory which is more relevant to the topic of the video.
As for Leeuwenhoek, his work was in optics. And althought he did observe the first microbes, he didn't study them that much. He drew everything he saw under his microscope, including bacteria (and sperm cells, he was very thourought in his research). Althought observing something is (sometimes) the first step to understanding it, it is not really what matters in that case. Pasteur understood a lot about the rabies virus without ever observing it for exemple.
So althought it would have been cool for them to be mentioned, I think the video focused more on the understanding of what microbes are and I get why they got left out.
Leeuwenhoek was mentioned in an earlier episode. You're in the wrong century.
Pierre Khalfi I mean, both of those men are usually considered fathers of microbiology. Since Jenner was Immunology, and that’s really an extension of micro. But I understand now why maybe he wasn’t included.
I honestly didn't know fermentation was necessary for bread, yogurt, and cheese.
This is so jokes man. The cool is jokes. (the jokes are cool).
Hey guys ! Great video, as always, thank you very much for that. I do have a question thought. You mentioned Pasteur's questionable ethics, which may not be that surprising given what we know others did back then. However we also know that Pasteur was a rather human guy, althought he used animal models, he wrote several letters where he states that he didn't like it and made some arrangements to make it easier for the animals. When it comes to human deaths due to the rabies vaccine, I never heard that he covered any deaths. I'm in no way saying it's not true, but we also know from letters he didn't want to use the vaccine at first. He wasn't confident enough to vaccinate Joseph Meister (the first kid to be saved), and only agreed because of the mother's insistance and the fact that the kid was going to die of rabies anyway. Other sources that reported on that event confirm that Pasteur was very concerned and cared a lot for the boy's safety. That's why I'm a bit confused, again I'm in no way saying you're wrong, I'm just curious about something I never heard before. So could you give me a source for that info so I can learn a bit more about the story ?
any more microbiology lectures??
I've deveopled this weird habbit of falling asleep to Crash Course presented by Hank Green. Sometimes but only sometimes even Mike Rugnetta, but NONE OF THE OTHERS.
It has come to the point i can't fall asleep if i don't play some Crash Course-Hank Green in my earphones.
Something about his (and Mike's) voice and tone and rhythm just does it. I fall asleep before the 10-12 minutes are over. Its so weird.
Do I need help lol?
Mona I do this to videos of Jim Rohn or Earl Nightangale.
Isaac Arthur (futurism and sci-fi) works even better. I think it's just the fact that it is a bit hard to follow them if you are not focused, and that you don't need to watch their videos to understand, so you can close your eyes.
this is the newest comment in 2 months
Thank you for giving Nicolas Appert a shout-out, if only a brief one. He doesn't get enough credit for inventing the canning/bottling of foods.
I feel that Hank is a bit different compared to the other videos I’ve watched. Great information!! I’m in micro now!!!!
"You know nothing John Snow" Please tell me I'm not the only Extra History fan here?
Nah dude, it was Walpole.

You are not alone!
WALPOLE!!!!

"Sniff the turkey." -Hank Green, 2018
We can reconcile Schlieden, Schwann, and Huxley's theories.
Schlieden and Schwann - was focused on the STRUCTURE of cells
Huxley - was focused on the FUNCTIONS of cell organelles.
Therefore, they explain the same topic with different perspectives.
Hello Hank, it's Wednesday.
Time for another semester of nursing school!
I love watching all of these videos and I've been subscribed since the very beginning! I have to ask, though, as someone who is studying both business and a social science... Can you guys think about doing social sciences? Maybe anthropology (I have a particular bias to this discipline)? I absolutely love anthropology, and you guys could break it down into like four subsections of the general course, each being one of the four branches of anthropology: archaeology, linguistics, biological/physical anthropology, and cultural anthropology. I just thought it was an idea worth thinking about!
Am I the only one who doesn't know who John Snow is?
Oops, missed the part about Antoni van Leeuwenhoek 🤷🏼♂️
Then go rewatch the earlier episode he was in.
Van Leeuwenhoek is covered in The New Anatomy. Would have been good to have mentioned him here just to link things up.
I needed to learn about Charles Darwin and watched one video then said "ok one more" 10 episodes later it's 10:30 and I started at 8:00 PLZ help!
Who tha fock is John Ice
Y'all whining abou...?
Lister was the name of a guy who helped create hygienic practices? Huh!
Now I know where the mouthwash gets its name from!
Don't eat gross trash
Since I started watching this series I wondered about the background tables, graphs, and diagrams that appear behind the portraits and "Conclusions." Could someone give me a list of them or point me to a place where I may learn more about their history? Thanks in advance!
I really enjoy this guy in the crash courses. He makes it so fun to learn the material. He also has a sense of humor. The first of both my colleges refer each class to this guys crash courses.
I'd be interested to see Joseph Lister and Florence Nightingale's timelines side by side.
Waiting for the jon snow comments to appear
Hank you missed an excellent opportunity to have a dream guest appearance from Alton Brown and his yeastie burping socks puppets. :(
I love microbiology but I'm a germaphobe, contradictory I know.
Maya Harper That’s not contradiction.
Maya, +T D was surely assuming that by germs you meant microscopic life in your vicinity.
If you did, then he has a point: only a fraction of this planet's microbiome consists of those germs. The pathogenic ones are even fewer.
If you hadn't tried yet, why not visit the library and fetch books on microbiology? The idea being that by getting to know germs you eventually will lose your fear of them. Anyways, good luck.
@@XmarkedSpot I'm already studying microbiology so I know this, and I'm not a germaphobe in that sense (I'm not sure how to explain it exactly).
+Maya, it's fine, no explanation needed (:
Good luck and have fun with your studies, cheers
@@XmarkedSpot thank you :)
Whoa dude. Just had a dream in which I was standing in front of you for a tutoring class and your brother's new book came up in the conversation. I made a comment about how well it's selling (I'm a bookseller!). You looked at me pretty agreived and said "no it's my book. I'm Hank"
I was confused. But then my dream moved on and even more confusing things happened.
Funny to wake up to one of the videos of that awesome series.
Microbiologists get paid up to £100,000 a YEAR
Can you guys do a series on modern history of medicine (i.e. from the 1700s onwards)?
Oh God waiting for Gregor Johan Mendel........ Pls Crash Course upload fast.
Next time: everyone's fave - Punnett squares.
Mitochondria is the powerhouse of the cell.
Indeed, comrade.
This is helping me get a job in a lab. So thank you for this. It is timelessly helpful.
john snow might not have proven germ theory but shout out for being epidemiologist #1 from a public health student!
Binge-watching this playlist.. now my head hurts, 😅
CRASH COURSE MICROBIOLOGY!!!!!!!!!
If I weren’t into medicine, I’d be doing an MS in microbiology. Thanks, Hank
Sorry for being nitpicky - but the dude is called KOCH, not COKE... :/
Wwwwwwoooooooowwwww😁😁😁😁😁😁
I watch Crash Course for the majority of my classes, I will be starting microbiology here in a few months, this video was great, but definitely would be amazing if there is a whole playlist on microbiology
FYI: Science Digest march 1978 study declares Colloidal Silver #1 anti-microbial known to Man, works by destroying the enzyme responsible for oxygen metabolism in single cell organisms, while being harmless to multi-cell organisms!
Hello! Please correct the formula of carbon dioxide shown at time 4:37! The number "2" should be written as a subscript, not a superscript. (:
I see the inspiration for the John Snow character :D
👍
I'm surprised we still started in the 19th century. (Also I guess we're not doing history of linguistics or social science...at least not yet). If he's ever going to cover Foucault and post-structuralist histories (of science, or in general) then maybe he'd cover aleast Structural Linguistics and what came after, if not Structuralist and Post-Structuralist Sociology.
Hey I know that Vitruvian Man, why paint it white though? It looks better in faux-bronze.
Koch as in Robert Koch rhymes with Loch as in Loch Ness.
Other germans here who loled at how they pronounced Koch? Usually, the pronounciation of german names is not to far off but here I always had an mental image of a Coke Bottle rather than a Cook.
Here's an interesting thought... You don't discover microbiology until you discover glass.
You need glass, which is a combination of silicon and calcium, to make lenses to see the microbes, that made the calcium deposits.
So we probably wouldn't be able to see the microbes if the microbes never existed.
Hank's intonation & diction is slightly different compared to miss Olivia's. Could someone kindly impart what distinctive accents do they both have?
The mitochondria is the POWERHOUSE of the cell.
Wait, did I miss him talking about Semmelweis? That's my favorite science history story ever!
No mention of Anton Van Leeuwenhoek? He was the first to discover microorganisms, wasn't he?🤔
Except you didn’t give the African’s any credit.
Why did you guys hyphenate microbiology? I've just never seen it hyphenated before lol
Omnis cellula e cellula
Okay interesting, but can you tell us how they work and how they work with your brain and how they relate to ones sense of self as they affect our decisions?
Who tha fock is John Ice
Y'all whining abou...?

❤ crash course....
LUCIUS SATAN yes
Microorganisms can be extremely beneficial. We need living soil.
Change the video to 2x now you can study crashed crashed course
You should do a crash course Microbiology!!
It’s nice to know that humanity is making massive science gains thanks to Game of Thrones
Surely that's the wrong pronunciation of Koch
What about Edward Jenner the Father of Vaccines
The broad street epidemic was covered on extra history...
So if biogenesis is true, that living things comes from other living things, how did life on Earth start? I thought that in the theory of evolution living matter literally came from non-living matter? Isn’t this a contradiction, that both biogenesis and abiogenesis are true?
Study about Chemical evolution, you'll find the answer.
was trying to forget GoT til mid 2019, but now I can't wait no longer
I love it when people mispronounce german surnames. :)
Hi
What did fermentation mean before Louis Pasteur
Can you all do a video on Causative Agents in Microbiology?
