    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!

      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.

    • @jackoriley7156
      @jackoriley7156 11 ปีที่แล้ว +5

      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.

    Lastly - I think there should be an order-able diploma we can hang to show that we watched and vaguely understood EVERY episode :D

  • @TechLaboratories
    @TechLaboratories 11 ปีที่แล้ว

    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.

    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 :')

    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.

    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. 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. >:(

    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.

    • @Mobius14

      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.

  • @aidanlam5336
    @aidanlam5336 7 ปีที่แล้ว

    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.)

    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.
