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.
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.
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.
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.
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
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!
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.
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.
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 ?
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?
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.
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!
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.
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.
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!
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?
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.
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.
Delving into the wide, wide word of tiny microbes! SOME could cause diseases and SOME can do wonders! AMAZINGLY tiny! Amazingly SIMPLE YET AMAZINGLY DIFFICULT TO DISCOVER!
Antonie van Leeuwenhoek is considered a father of microbiology as he observed and experimented with microscopic organisms in 1676, using simple microscopes of his own design. Scientific microbiology developed in the 19th century through the work of Louis Pasteur and in medical microbiology Robert Koch. Microbiology is the scientific study of these microorganisms. Microorganisms are those organisms that are too small to see with the naked eye and include things like bacteria, fungi, and viruses. Matthias Schleiden had stated that plant tissues were composed of cells. Theodor Schwann demonstrated the same fact for animal tissues, and in 1839 concluded that all tissues are made up of cells: this laid the foundations for the cell theory. Schwann also worked on fermentation and discovered the enzyme pepsin. Thankfully for the different variety of scientist who discovered, proposed and invented the different kinds of organisms in our world's. Without them we can't be able to know about the history of the science technologies, specifically thanks for those scientist who discovered such diseases so we can be able to cure and prevent those diseases that coming from our bodies or in our environment. This is a very big help for every human individuals. thanks for our anciestors:)
Microbes are invisible: they're single cells. So to understand microbes that is , to do microbiology scientist first needed to study cells .

Scary how small organisms like bacterias cause a lot to humans, plants, animals, and food. And it's amazing how humans discover this bg sciencing a lot to gain knowledge. Because of their hard work in microbiology, they manage to find cure for diseases which are very importany for humans to stay alive and they also manage to explain how bacterias work in food and liquid substances that made us understand how to preserve food, ferment wines, and other things. The invention of microscope really helpes a lot of scientists and shaped our world today. These scientists deserve a lot of praise for their hard work. They saved a lot of humas and explained how food works with the help of bacterias. Kudos to them!
This video implies that this tiny microbes are very essential to us. Since it gaves advantageous things to us. It is so amazing how this tiny creature made a lot of contrubutions to us, like our food. Through fermentation that uses microbes, beer, wine, yougurt, cheese and bread were brought to us. How stunning this scientist discovered this thing. Our human health was beneficient to what they discovered they eliminate or should i say they prevent disease that might cause us to death. This scientist were much honored, they can be called hero indeed. One more thing all thanks to this technology, microscope because of this things changes and a lot of discoveries were taken by us.
Microbioy is the study of small living things. Generally this means living things that are too small to see without the use of a microscope. these microbiology can be used in applied science, helping agriculture, health and medicine and maintenance of the environment. This concluded that Microorganisms are extremely important in our everyday lives that without the help of this crazy scientist who discovered microbes we can't see its value. Indeed some could cause diseases but it also gave benefits.
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.
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.

PLEASE make a full set of Microbiology crash courses I would legit pay money to watch them. The anatomy ones have saved my life.
Can we please get more crash courses in microbio?
like ikr
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
Of course bacteriology started in GERMany 😉
This GERMan needs a tissue ^^
That's why they are called germs. Not the other way around.
I feel like there will be a new interest in microbiology after this coronavirus pandemic is over
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
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.
😭🙌🏽 I survived Anatomy and Physiology classes, thank you Crash Course. Now, its microbiology and parasitology. 😅
Alton Brown presents Pasteur as a huge hero, and I have to agree.
2024 and I’d say too: please do a complete course on Microbio!
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.
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.
please put out more microbiology videos kinda gives me motivation to study.
For one I would like to say that this recording of common information is mostly correct and benificial to the public.
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.
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.
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.
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
This is helping me get a job in a lab. So thank you for this. It is timelessly helpful.
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 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!
I'd be interested to see Joseph Lister and Florence Nightingale's timelines side by side.
I Loeb this channel
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
any more microbiology lectures??
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 feel that Hank is a bit different compared to the other videos I’ve watched. Great information!! I’m in micro now!!!!
John Snow seemed to know a whole lot, ironically.
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).
Mitochondria is the powerhouse of the cell.
Indeed, comrade.
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.
"Sniff the turkey." -Hank Green, 2018
john snow might not have proven germ theory but shout out for being epidemiologist #1 from a public health student!
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.
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!
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).

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.
Moreee microbiology pleaseee🙏🏻
You should do a crash course Microbiology!!
Koch as in Robert Koch rhymes with Loch as in Loch Ness.
This is better then my year 9 science class
Binge-watching this playlist.. now my head hurts, 😅
"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!!!!
Here
Hello Hank, it's Wednesday.
Time for another semester of nursing school!
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!
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?
Can you guys do a series on modern history of medicine (i.e. from the 1700s onwards)?
Next time: everyone's fave - Punnett squares.
If I weren’t into medicine, I’d be doing an MS in microbiology. Thanks, Hank
I see the inspiration for the John Snow character :D
Thank you very much crash course
Wait, did I miss him talking about Semmelweis? That's my favorite science history story ever!
Your explanation helps lot thx
Oh God waiting for Gregor Johan Mendel........ Pls Crash Course upload fast.
Thank You 🔬
The mitochondria is the POWERHOUSE of the cell.
CRASH COURSE MICROBIOLOGY!!!!!!!!!
Can you all do a video on Causative Agents in Microbiology?
Lister was the name of a guy who helped create hygienic practices? Huh!
Now I know where the mouthwash gets its name from!
was trying to forget GoT til mid 2019, but now I can't wait no longer
What is a good video for microbio?
Add chapters 11 and 12 to the playlist already.
my favourite subject
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.
Microorganisms can be extremely beneficial. We need living soil.
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!
LOVE ETHANOL.
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.
you always good explaining thank you god bless
Goodness-been looking for his micro videos hehe
8:19 you can't prove a negative!

It’s nice to know that humanity is making massive science gains thanks to Game of Thrones
Great vid
Hank you missed an excellent opportunity to have a dream guest appearance from Alton Brown and his yeastie burping socks puppets. :(
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. (:
The art work👏🏼
The broad street epidemic was covered on extra history...
What did fermentation mean before Louis Pasteur
No mention of Anton Van Leeuwenhoek? He was the first to discover microorganisms, wasn't he?🤔
Who loves Crash Course History of Science?
Wait, what? I thought Hooke was the originator of cell theory.
He discovered cells in cork and coined the term, "cell"
@CrashCourse can you do Phytochemistry?
So many germ(an)s in this episode.
"in mice, and men... And PEAS"😂😂😂
Yay... My major subject
Microbiologists get paid up to £100,000 a YEAR
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.
Am I the only one who doesn't know who John Snow is?
Need more micro videos :)
the theory was kinda humorous
❤ crash course....
LUCIUS SATAN yes
interesting !
Hey I know that Vitruvian Man, why paint it white though? It looks better in faux-bronze.
What about akşemseddin? He wrote about our ilness because of we cant see so small organisma
