"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
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!
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!
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
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
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
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 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.
Is that a Professor Poliakoff shirt? That's from the "Losing fingers to Chemistry" episode, right?
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.
Thank you so much for this course, it makes me sad that it's over, it's been awesome.
Congratulations! to all of you who just like me finished this crash course, DFTBA
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 all the educational videos you share, they are really amazing!
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.
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
Thank you, this was a really helpful course, and the way yall presented the information was clear and concise.
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.
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
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
I wanted to learn about biogeochemical cycles and this was really helpful, thank you for delivering!
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.
HE'S WEARING A SHIRT WITH THE PROFESSOR ON IT!
Martyn Poliakoff
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!
No no no! Don't end the series! So much more to talk about! :)
But loving the upcoming pchycology series. My sister just last week asked, if you are making such videos. I can tell her the good news now :)
A Poliakoff shirt! :D
That farting moose animation just made my night :]
So glad to see Hank in a shirt with Professor Poliakoff from PerodicVideos!
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.
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!!!
CrashCourse Physics please
Landau Martin SciShow!
N. Presley its not strictly going into physics
Amazing series that taught me so much. Thank you crash course!
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.
you mixed up the charts in 5:18 and 5:26
CH₂O₂+O₂→6CO₂+6H₂O+ENERGY
C₆H₁₂O₆+6O₂→CO₂+H₂O+ENERGY
Thank God TH-cam has the 0.5 and 0.25 speed options... Hahaha
Great video as always!
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.)
Thank you, Hank and the whole team! Chemistry was great, looking forward to Psych!
You guys should do a physics crash course! Please!:)
Sry, got distracted by professor p's hair
Really helpful!
Have my test tommorow!
amazing series and thanks a lot
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?
can you do crash course physics? i love it, if you can do that
Thank you for everything! It was very helpful!
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.
Crashcourse physics!!!
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.
You explained everything so well that I already feel ready for my test!
That was fantastic. Well done!
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 helped so much in my AP Chem class! Keep it up, and consider covering Physics sometime. :)
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.
Periodic Table of Videos shirt ftw
A set of 118 shirts would be awesome.
PSYCHOLOGY!?!?!?!?!
YOU GUYS ARE DOING PSYCHOLOGY!!!!
*Little Dance*
Yay! Just finished the whole series!
awesome teacher....awesome series !!!
The shirt.
I do want that periodic table...
It explains clearly but wen it wil last longer it becomes boring.
thanks for the true awesomeness, crash course you are a world service. thanks for sharing and not being boring.
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.
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.
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
Thanks for doing these Hank.
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!
Hank, please, we need Crash Course Physics.
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
Thank you for the videos!
Brilliant series
Never stop caring, I like that ^^
Is that... Martyn Poliakoff?
Excellent! Thank you.
Thanks for all, Hank. Seriously!
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.
speed 0.75 thank me later
oooh this video was very helpful thank you
So excited for Crash Course Psychology!!!!
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 did it end?
Im stoked for the psychology courses (and yeah cool poliakoff shirt,it rocks)
wow. This informative. Thanks for the video.
PLEASE DO PHYSICS
5:20 CH2O2 should be CH2O right?
C6H12O6 + 6O2 --> 6H2O + 6CO2 + Energy
Psychology is mad interesting.
Thank you guy's you guys got it all !
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.
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.
Great course..Thanks a lot..
All your videos are really helpful and really easy to understand. Just a request. Could you do a course on organic synthesis. Thanks.
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
I just love crash course chemistry... Pls add more videos... Please
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!
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
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. >:(
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.
nice work
