I took 3 chemistry courses this year, and you all have been a tremendous help. My eyes are getting watery here, knowing that crash course chemistry is over, but I will always be a fan and support in whatever ways I can. Thank you so much!
My MCAT is already this weekend and since I graduated with a business undergraduate course, I have little to no background with Organic Chemistry. Having watched your Organic Chemistry series, I have learned so much and even though there's a lot more to it, I'm finally understanding more of the notes I've been reading since I'm learning Org Chem all on my own. Thank you so much for this series!
I have my AP Chemistry midterm tomorrow, and if it weren't for these videos I would probably fail. Thanks CrashCourse for taking the time to teach the world! :)
Thank you for all the information. I watch these at work while doing data entry stuff and it is the most rewarding part of my job to attain knowledge. This was a fun course, and I appreciate it, Hank Sensei. Now time to do a 2 week/ 6 episodes a day refresher before bio and A&P. You guys are awesome. Thank you. Keep it up.
I'm so pleased that I found this channel! It helps me a lot with school work and is a fun way to revise. The only thing I would say is that he speaks so fast that it's hard to take in all of the information but other than that, I'm really pleased😊
Rebecca Wood Why do people always complain that he speaks too fast? I am able to clearly understand each and every word he speaks without even putting much effort into it. And English isn't even my Native language.
I'm so freaking excited for Crash Course: Psychology! My passion is psychology and I'm so looking forward to these videos. I'm already excited for the day I can use them for my future classes!
Dear Hank, First of all, many many thanks for this marvelous video. I have to say, it has helped me tremendously in the understanding of a certain matter I am deeply concerned about and it also has helped me link several unattached concepts in my head. Also, I wish I had discovered Crash Course when I was in high school, it would have helped me inmensly, either way I love the way you and team make the topic introduction so easy to understand and of course, the beautiful graphics of Thought Café and the sound team :') Million thanks from a quite slow College Student.
I just hung my CC periodic table - I wanted to give it to my niece because it's cute and she could learn from a periodic table with clever creatures on it - but it's too awesome so I'm keeping it for me :) My labcoat is in the mail...apparently... Lastly - I think there should be an order-able diploma we can hang to show that we watched and vaguely understood EVERY episode :D
Awesome man big inspiration, help a lot i didnt understand chemistry and i thought it was boring, now im excited. ill try to make a good use of this understanding to do a better world
Yay! I work in psych, so this kind of thing is kinda fun. Not that I want to work with this patient population long-term, but I do enjoy learning about it. Plus, there are a LOT of nerdfighters who have anxiety and other mental "issues," so hopefully this will help us to all understand each other better.
have anyone noticed that the number of views fell down from 2.7 million views in the first video to 466K in this video(almost 63 % decrease). This shows how many people procrastinate important and interesting things like this.
Jack O'Riley By your logic the following is true: Carbon is an atom. I'm made of carbon. Therefore, I am an atom. This is a fallacious syllogism. At best you can say that ***** is made of tramps.
I took a logic and philosophy course last year so I know, but since TheRockybulwinkle said that carbon is a tramp, which is not logical in any way, I just thought I'd give up logic as well for that comment.
Please continue making more chem videos, there's so much more to talk about! Also make some hard maths ones (complex numbers, calculus, inverse trig etc.)
The cellular respiration equations (around 5:30) are not balanced. The products got switched. Easy mistake, no harm done. Just didn't see it as a comment so there it is.
Another great series from Hank! You really did a great job explaining Chemistry and making me not want to run for the hills when the word is mentioned.
So sad that crash course chemistry is finished. Felt super accomplished watching all episodes though...makes me more confident for AP Chem exam next week. Thanks SO MUCH HANK!! I'm such a big fan of crash course!
Mr.Green,Mr.Green! I think its the right time to start studying about the dominant species of the periodic table.I mean to say 'METALS and METALLURGY', isn't it?
Fantastic Hank! I love Psychology! (Hence why I'm getting a degree in it) Your course probably won't tell me things I haven't already learned before, but it's always good to refresh one's knowledge.
The chemistry course is fantastic! Are you going to make a chemistry course 2 sometime? That would be amazing. I learn so much an it's also in a very fun and interesting way!
Favorite chemistry episode! Great series, Hank. It may not have a lot of views now, but kids will use this resource for years and years to come. Also, as a 21 year old humanities grad student, this is accessible and interesting. DFTBA, homie.
Yea from the video on periodicvideos where he talks about someone losing two fingers or something and then does that gesture which looks like metal horns or the mano cornuta, which is a good thing, at least to me.
Yea but crash course doesn't want to step on anyone's toes, besides there hasn't been many videos on psycology on youtube that I know of so I for one am eagerly expecting this.
I love you man. Just watched CrashCourse History and went on (after hours of procrastination) to do some biology and look and theres a crashcourse video on the topic and its moderated by MY MAN JOHN GREEN :)))
Great summary of the Carbon Cycle. BUT - octane is not the main ingredient in gasoline. The octane rating is a rating system based on the combustion of pure isooctane to give a scale for gasoline autoignition pressure. In fact it is possible to change a gasoline's octane rating without actually changing its octane or isooctane content. Gasoline is hugely varied in its hydrocarbon content, and can vary significantly from vendor to vendor as to its exact composition so long as the energy contained per unit volume remains according to national standards.
Well yes, but in that case CH2O is actually referring to glucose, as C12H6O12 is the molecular formula for it, while CH2O is the empirical formula for it.
you made a video on polymers so can u make one on ceramics and composites. i know the last vid you did was in 2014 and now it is 2017 but it would help alot. and i support the idea of doing for all subjects.
Because cuntservaturds hate hearing hard reality & hard necessary truths. They want to live in their fantasy bubble where there exist no consequences to anything, to any of their habits.
With that well said the solution to our ever increasing CO2 volumes is to raise more gardens and drive less. If we had more gardens we would drive less to the jobs because food would be our number 1 provision already taken care of right outside our doors within walking distance. PICK AND EAT! More trees means more O2 produced and more absorption of CO2.
@tyler s...my information comes from the AR4 Working Group 1 technical documents of the IPCC. I have not worked my way through the whole AR 5 doc yet, but CO2 has a fixed heating value. It is not some zombie compound that makes bad things happen.
While I haven't really learned anything new from this video, the whole topic of the carbon cycle and it being out of whack in recent centuries is not only interesting and fascinating to me, but also incredibly scary.

"Awareness isn't the same thing as understanding."
- Hank Green, 2014
Yip. You DO NEED math to prove your state.
I'm fairly confident that a definition of success is: Hank wore a t-shirt that I designed in a Crash Course video.
I took 3 chemistry courses this year, and you all have been a tremendous help. My eyes are getting watery here, knowing that crash course chemistry is over, but I will always be a fan and support in whatever ways I can. Thank you so much!

Oh hey this is the school system on a nutshell
Its kinda sad he no longer makes chemistry videos :(
it sucks that he never did an organic chemistry series
Kinda?
@@yess.6558 Who knows though. Maybe he'll do organic chemistry after he's done with history of science.
@@taylorkohls5268 some foreshadowing right there
There is much more to learn
Thank you for all the information. I watch these at work while doing data entry stuff and it is the most rewarding part of my job to attain knowledge.

More organic chemistry and biochemistry please
Hell Yes. Btw Hoo'ah.
I'm so pleased that I found this channel! It helps me a lot with school work and is a fun way to revise. The only thing I would say is that he speaks so fast that it's hard to take in all of the information but other than that, I'm really pleased😊

I can understand him fine, it's just taking the information in that's the hard part - it goes in one ear and out of the other haha😁 FROP DESAI
Rebecca Wood
Lol. Ok. Sorry, my bad.
It's fine haha😊 What's your native language then? FROP DESAI
My native language is Gujarati.
This series was great, never really learnt chemistry well before and this really helped me. Thank you Hank and team :D
Thank you so much for this course, it makes me sad that it's over, it's been awesome.
Will you PLEEEEEAAAASSSSSS make physics crash courses and math(calculus, trig) courses!!!!! Thank you
I completely agree with you. please do this, crash course!
+potteristical xxx Physics
ORGANIC CHEMISTRY
diba seleh. He can't. Because you can't lie about math. Sorry.
For Sure Organic Chemistry
Congratulations! to all of you who just like me finished this crash course, DFTBA
I'm so freaking excited for Crash Course: Psychology! My passion is psychology and I'm so looking forward to these videos. I'm already excited for the day I can use them for my future classes!

Is that a Professor Poliakoff shirt? That's from the "Losing fingers to Chemistry" episode, right?
I just hung my CC periodic table - I wanted to give it to my niece because it's cute and she could learn from a periodic table with clever creatures on it - but it's too awesome so I'm keeping it for me :)

@@stevenutter3614 haha.. that was 5 years ago
@@moisus. yup
Thank you so much for all the educational videos you share, they are really amazing!
Thank you, this was a really helpful course, and the way yall presented the information was clear and concise.
Crash Course chemistry , is the best way to learn and revise , all i hope is they come up with Crash Course Chemistry Season 2. :D
He's wearing Professor Poliakoff :D
Awesome man big inspiration, help a lot i didnt understand chemistry and i thought it was boring, now im excited. ill try to make a good use of this understanding to do a better world

Carbon is a boss. Good episode, Hank.
No, carbon is a tramp :p
***** You are made of carbon, therefore you just called yourself a tramp. Well played sir, well played.
Jack O'Riley
By your logic the following is true:
Carbon is an atom.
I'm made of carbon.

I'm referencing the first crash course biology.
I wanted to learn about biogeochemical cycles and this was really helpful, thank you for delivering!
Please continue making more chem videos, there's so much more to talk about! Also make some hard maths ones (complex numbers, calculus, inverse trig etc.)
HE'S WEARING A SHIRT WITH THE PROFESSOR ON IT!
Martyn Poliakoff
The cellular respiration equations (around 5:30) are not balanced. The products got switched. Easy mistake, no harm done. Just didn't see it as a comment so there it is.
I noticed that, too.
Another great series from Hank! You really did a great job explaining Chemistry and making me not want to run for the hills when the word is mentioned.

You guys should do a physics crash course! Please!:)
That farting moose animation just made my night :]
This series helped so much in my AP Chem class! Keep it up, and consider covering Physics sometime. :)
Thank you, Hank and the whole team! Chemistry was great, looking forward to Psych!
Sry, got distracted by professor p's hair
Mr.Green,Mr.Green! I think its the right time to start studying about the dominant species of the periodic table.I mean to say 'METALS and METALLURGY', isn't it?
Amazing series that taught me so much. Thank you crash course!
thanks for the true awesomeness, crash course you are a world service. thanks for sharing and not being boring.
can you do crash course physics? i love it, if you can do that
I started my year in chemistry predicted a D, now thanks to crash course my teacher thinks i will get an A, please don't let it end!!!
Fantastic Hank! I love Psychology! (Hence why I'm getting a degree in it) Your course probably won't tell me things I haven't already learned before, but it's always good to refresh one's knowledge.
You explained everything so well that I already feel ready for my test!
Thank God RUclips has the 0.5 and 0.25 speed options... Hahaha
Great video as always!
A Poliakoff shirt! :D
The chemistry course is fantastic! Are you going to make a chemistry course 2 sometime? That would be amazing. I learn so much an it's also in a very fun and interesting way!

CrashCourse Physics please
Landau Martin SciShow!
N. Presley its not strictly going into physics
Crashcourse physics!!!
Im stoked for the psychology courses (and yeah cool poliakoff shirt,it rocks)
amazing series and thanks a lot
you mixed up the charts in 5:18 and 5:26
CH₂O₂+O₂→6CO₂+6H₂O+ENERGY
C₆H₁₂O₆+6O₂→CO₂+H₂O+ENERGY
I do want that periodic table...
It explains clearly but wen it wil last longer it becomes boring.
Yay! Just finished the whole series!
Thank you for everything! It was very helpful!
Is that professor Poliakoff on your t-shirt?
Exactly what I thought! :D
Yea from the video on periodicvideos where he talks about someone losing two fingers or something and then does that gesture which looks like metal horns or the mano cornuta, which is a good thing, at least to me.
I wish there was also Crash Course Computer Science and Crash Course Calculus
Yeah!! Computer Science 😁
There is now. Crash Course computer science.
There is now
All your videos are really helpful and really easy to understand. Just a request. Could you do a course on organic synthesis. Thanks.
That was fantastic. Well done!
Periodic Table of Videos shirt ftw
A set of 118 shirts would be awesome.
Hank, please, we need Crash Course Physics.
Thank you guy's you guys got it all !
plz their more of chemistry for u to cover so i would like if this series continues
but thanks for sharing the awesomeness of chemistry with us
Aw I was really hoping for physics. But psychology is interesting I guess..
physics would've been awesome!!!!
are you alive....... just asking
LonelyStranger probably
Why Psychology before Physics??!?!?!?!?
Jonah Stalknecht But none of that channel has a beginning-to-end course on Physics!
probably because they know more about psychology than physics.
Yea but crash course doesn't want to step on anyone's toes, besides there hasn't been many videos on psycology on youtube that I know of so I for one am eagerly expecting this.
LanttuLoL Yeah, I wonder what happened to PsyPhile
Hank has stated that he doesn't feel he knows enough about physics to teach it yet.
Really helpful!
Have my test tommorow!
I love you man. Just watched CrashCourse History and went on (after hours of procrastination) to do some biology and look and theres a crashcourse video on the topic and its moderated by MY MAN JOHN GREEN :)))
PSYCHOLOGY!?!?!?!?!
YOU GUYS ARE DOING PSYCHOLOGY!!!!
*Little Dance*
Never stop caring, I like that ^^
Thanks for doing these Hank.
Thanks for all, Hank. Seriously!
The shirt.
Is that... Martyn Poliakoff?
oooh this video was very helpful thank you

why did it end?
yo Carbon i'ma let you finish and all but Oxygen is the best element of all time... ALL TIME!
Lmao still funny 5 years later
awesome teacher....awesome series !!!
Thank you for the videos!
PLEASE DO PHYSICS
CH2O isn't a "thing"!? That's formaldehyde, sir!
Well yes, but in that case CH2O is actually referring to glucose, as C12H6O12 is the molecular formula for it, while CH2O is the empirical formula for it.
I guess the more adequate notation would have been (CH2O)n
Jason Brody Thanks, I'm aware - I was just being a pedant.
Jason Brody uhhhhh i think you mean glucose is C6H12O6
i think niyaz is right.
Sad to see this course come to an end, I enjoyed it!
WOHOO!
awesome, have psychology now and have been hoping/ suggested it :D KBA ;) (keep being awesome)
5:20 CH2O2 should be CH2O right?
C6H12O6 + 6O2 --> 6H2O + 6CO2 + Energy
speed 0.75 thank me later
you made a video on polymers so can u make one on ceramics and composites. i know the last vid you did was in 2014 and now it is 2017 but it would help alot. and i support the idea of doing for all subjects.
I just love crash course chemistry... Pls add more videos... Please
Will there ever be crash course maths?
Or crash course physics
thedominomaster101 www.khanacademy.org/
Try it out, its free and it's awesome :-)
i have but its hard to do that while still having school and/or homework
Why is this comment section full of climate change sceptics?
Maybe because of all the morons who think there was a time when climate did not change.
because they don't have a uni to go to
Because cuntservaturds hate hearing hard reality & hard necessary truths. They want to live in their fantasy bubble where there exist no consequences to anything, to any of their habits.
So excited for Crash Course Psychology!!!!
CRASH COURSE PSYCHOLOGY?!?!?!?!? :O :O That made my day! Heck no, my whole week!!!!!!!! Hank, you're awesome, I can't wait!
With that well said the solution to our ever increasing CO2 volumes is to raise more gardens and drive less. If we had more gardens we would drive less to the jobs because food would be our number 1 provision already taken care of right outside our doors within walking distance. PICK AND EAT!

He talks way too fast 😂😹
This is supposed to be a review and you can decrease the speed if you want.
That's why there's a rewind button. Lol
@tyler s...my information comes from the AR4 Working Group 1 technical documents of the IPCC. I have not worked my way through the whole AR 5 doc yet, but CO2 has a fixed heating value. It is not some zombie compound that makes bad things happen.
wow. This informative. Thanks for the video.
Is this actually interesting for anybody who understands this?
Sure! Why not?
While I haven't really learned anything new from this video, the whole topic of the carbon cycle and it being out of whack in recent centuries is not only interesting and fascinating to me, but also incredibly scary.
It's not that difficult to figure out.
I thought the limestone factoid was interesting.
I study this kind of science in school. However, I like to watch it. It helps reinforce what I already knew. Haha
he speaks so fast I sneezed and missed the whole cycle...
True
They should have an option to make him go slow
xD ikr
Set video to 0.5x speed
Nice shout out to Professor Poliakoff! And well done as usual Hank. Thank you.
Keep up the great work. I'll miss this series. If I ever have to fall back on teaching I'm going to copy you lol.
