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! :)
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!
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.
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
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.
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.
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.
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?
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.
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.
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.
At 1:43 when he said "Heat" the captions said "Head" and I died laughing because I imagined a massive durpy face floating through space! HAHAHHAHAHHAHAHHAHAHHA!
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'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!
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 love how people always neglect the fact that global temperatures have not increased since 1998!! Thank you Alan Jones for bringing light on this 'global warming' farce.
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.
Over the course of the past two weeks or so, I have watched this Chemistry series almost religiously. Watching 3 to 4 episodes per day.....I know just as much about chemistry now as when I first started. Very confusing subject.
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.
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.
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.
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.
No!! Not the end! I loved this course. It was an essential part of me........... But I have recently become interested in psychology, weird that a course comes up when I need it! :) BTW, Please make a Crash Course Physics!!! I don't want Crash Course Chemistry to end! :-( I'm going to watch this all over. Again. I'm only 13 and look at the effect this course had on me! I'm a prodigy now!!
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.
While I love this channel, and mostly like this video, I'm finding it hard to actually 'like' the video. You failed to explain properly the different types of cycles and how their cyclical rates vary. Most importantly you failed to explain why this is important for the whole fossil fuel issue, being part of one cycle that does not naturally bleed into the other so quickly, as we are making it do. I feel that the way you lumped them together will lead people to believe that there is far less of a danger than is actually there. The relevant importance of this makes me very disappointed, Hank. >:(
These courses typically are aimed at grade 12 or first year university level. That's about as far as any of most grade school or intro level chemistry's in university went, so it made sense to stop there.
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.)
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.
no, No, NOOOOO I NEED YOU FOR ORGO!!!! You're the reason I passed general chemistry! If you are not swayed by this comment (it would be a first for TH-cam), do you recommend any other channels that are good for orgo?

"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 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! :)
Oh hey this is the school system on a nutshell
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!
More organic chemistry and biochemistry please
Hell Yes. Btw Hoo'ah.
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!
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
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.
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.
I'm referencing the first crash course biology.
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
@@stevenutter3614 haha.. that was 5 years ago
@@moisus. yup
Is that a Professor Poliakoff shirt? That's from the "Losing fingers to Chemistry" episode, right?
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.
Congratulations! to all of you who just like me finished this crash course, DFTBA

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.
HE'S WEARING A SHIRT WITH THE PROFESSOR ON IT!
Martyn Poliakoff
He's wearing Professor Poliakoff :D
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
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.
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!!!
I and others have really been looking forward to a physics crash course, but in the absence of that, psychology sounds like a great idea.
That farting moose animation just made my night :]
So glad to see Hank in a shirt with Professor Poliakoff from PerodicVideos!
Thank God TH-cam has the 0.5 and 0.25 speed options... Hahaha
Great video as always!
I truly love crash course chemistry I am an 8th grader and I think I just learned college level chemistry. Hank is the best.

Sry, got distracted by professor p's hair
this is exactly why understanding science is important.
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
This series was great, never really learnt chemistry well before and this really helped me. Thank you Hank and team :D
PSYCHOLOGY!?!?!?!?!
YOU GUYS ARE DOING PSYCHOLOGY!!!!
*Little Dance*
I didn't know any chemistry before this channel but now I'm like a chem genius. World history next please!!!
Crashcourse already has a World History series.
***** Ah I see them now, thanks
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.
At 1:43 when he said "Heat" the captions said "Head" and I died laughing because I imagined a massive durpy face floating through space! HAHAHHAHAHHAHAHHAHAHHA!
Hank, please, we need Crash Course Physics.
I can't wait for Crash Course Psychology
speed 0.75 thank me later
Nice shout out to Professor Poliakoff! And well done as usual Hank. Thank you.
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.
Thanks for the great video Hank. I totally want a Professor Poliakoff shirt.
You can find it here: dftba.com/product/14y/The-Professor-Shirt
You guys should do a physics crash course! Please!:)
They need a crash course for chem over the topic of mole conversions and empirical conversions
I do want that periodic table...
It explains clearly but wen it wil last longer it becomes boring.
Yay! a psychology teacher that doesn't bore you to death!
A Poliakoff shirt! :D
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!
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
CRASH COURSE PSYCHOLOGY?!?!?!?!? :O :O That made my day! Heck no, my whole week!!!!!!!! Hank, you're awesome, I can't wait!
you mixed up the charts in 5:18 and 5:26
CH₂O₂+O₂→6CO₂+6H₂O+ENERGY
C₆H₁₂O₆+6O₂→CO₂+H₂O+ENERGY
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.
Periodic Table of Videos shirt ftw
A set of 118 shirts would be awesome.
I love how people always neglect the fact that global temperatures have not increased since 1998!! Thank you Alan Jones for bringing light on this 'global warming' farce.
.....the ice caps are still melting. in 2019. yeah, global temps have increased since 1998...
Is that... Martyn Poliakoff?
also that martin poliakov t-shirt is BOSS!!!!
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.
Tomorrow is my chemistry exam and I am procrastinating my study by watching these videos.
Crashcourse physics!!!
Over the course of the past two weeks or so, I have watched this Chemistry series almost religiously. Watching 3 to 4 episodes per day.....I know just as much about chemistry now as when I first started. Very confusing subject.
The shirt.
Teaching biology/biochemistry with graphics and audio; the only true reason to crack the farting noice!
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
Hurray for psychology! One of my favorite subjects!
can you do crash course physics? i love it, if you can do that
Dear Hank,

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
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.
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.
I GOT THE POSTER AS A LATE CHRISTMAS PRESENT I LOVE IT IT'S SO COOL
PLEASE DO PHYSICS
Dear Thought Cafe,
You guys do great work.
Never stop caring, I like that ^^
Thanks for all, Hank. Seriously!
5:20 CH2O2 should be CH2O right?
C6H12O6 + 6O2 --> 6H2O + 6CO2 + Energy
My first CrashCourse. Amazing! I interpret climate change for a national park and this really helped improve my understanding of carbon.
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
Thank you, Hank and the whole team! Chemistry was great, looking forward to Psych!
why did it end?
PLEASE MAKE A PHYSICS CRASH COURSE!!!!!!! Higher level maths would also be great
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.
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
yea, he just talks fast
No!! Not the end! I loved this course. It was an essential part of me...........
But I have recently become interested in psychology, weird that a course comes up when I need it! :) BTW, Please make a Crash Course Physics!!! I don't want Crash Course Chemistry to end! :-( I'm going to watch this all over. Again. I'm only 13 and look at the effect this course had on me! I'm a prodigy now!!
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
I wanted to learn about biogeochemical cycles and this was really helpful, thank you for delivering!
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.
Thank you. I love your show. You, Vsauce, CPGrey and others have totally replaced TV for me. Sooooo much better.
While I love this channel, and mostly like this video, I'm finding it hard to actually 'like' the video.

The relevant importance of this makes me very disappointed, Hank. >:(
I like the captain planet reference towards the end there XD
How pointless. Ending chemistry when you just barely covered any of O-chem.
These courses typically are aimed at grade 12 or first year university level. That's about as far as any of most grade school or intro level chemistry's in university went, so it made sense to stop there.
These are American AP courses so if you want to know what they cover and what topics they are going to cover in future then just Google AP courses.
CRASH COURSE. Not Full Course. Go take an AP class if you want to know that stuff.
It's a general chemistry sequence. It basically covered (though in much less detail) my first year of chemistry at college.
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.)
YOU TALK TOO FAST THIS IS IMPOSSIBLE I GIVE UP
Sixty Symbols shirt? Looks like from the episode where he quoted "I had a *hand* in this reaction".
science exam in exactly 7 hours, it is 1 am and this is the closest to notes that i've got. pray for me xP
how was the exam?????????????
anonymous hacker haha great thanks, crashcourse is officially bea, i think it's the only reason anyone passes anything haha
+alice sarah yeah... i have a unit test in 17 hours... i am soo scared
anonymous hacker it's ok, we will get through this, what are you studying?
+alice sarah wait it's probably the carbon cycle isn't it haha
I know you guys are doing civics, astronomy, physiology and economics next year, but maybe in 2016 could you do a series on particle physics?
Yay! Just finished the whole series!
They're not rocks! They're minerals, Marie!
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.
Thanks It helped me get a A* in my science test and 100%
It probably wasn't a good idea to start this Crash Course in the 40s. Well, off to the beginning of the playlist!
no, No, NOOOOO I NEED YOU FOR ORGO!!!! You're the reason I passed general chemistry!
If you are not swayed by this comment (it would be a first for TH-cam), do you recommend any other channels that are good for orgo?
Khan Academy helped me get through OChem1. Not really the same style, but certainly adds an extra voice in the head if that makes sense.
