Crash Course: BiologyAnd thus begins the most revolutionary biology course in history. Come and learn about covalent, ionic, and hydrogen bonds. What about electron orbitals, the octet rule, and what does it all have to do with a mad man named Gilbert Lewis? It's all contained within.

The molecules that make up every living thing - carbohydrates, lipids, and proteins - and how we find them in our environment and in the food that we eat.

The city of Eukaryopolis - the animal cell that is responsible for all the cool things that happen in our bodies.

How cells regulate their contents and communicate with one another via mechanisms within the cell membrane.

Why plants are so freaking amazing - discussing their evolution, and how their cells are both similar to & different from animal cells.

The "economy" of cellular respiration and the various processes whereby our bodies create energy in the form of ATP.

Watching the first couple of minutes of the second video, I think an orgy image would make the image of water hydrogen bonds more memorable. The molecules cohere in an orgy of attraction between the negative oxygen and positive hydrogen.

I enjoyed the video. Hank obviously has read some memory books or watched some memory videos, because he knows that sex images create memories. If you don't get anything else out of the video other than carbon's promiscuity, you got more than most people got out of high school chemistry.

thank you so much. I was looking for this video perhaps. Because emm
not from the field of biology. i am mechanical engineer but want to
learn about all other subjects and similar is biology so that at least i
am not blind when there comes a biology...

is or will there be videos for maths and physics?

My question is, what happen to the beer I had in the refrigerator?

I found the presentation fun, maybe not James Burke fun but, a good reminder of basic sciences in a bit of humorious manner.

For my point of view the biology part is much more irritating than history. Personally I think making fun of history is interesting and sometimes illuminating but making fun of natural science really does not make any sense. Any by all means, to study natural science in general is NOT to accept facts, but to know why it works (theory) and how it is proven (experiments), i.e. following the scientific method. And to a certain degree, applying scientific method requires questioning intuition. Just pouring facts and say 'accept and remember this' is exactly how science should not be.

Intolerable presenting style. Appears to be meandering bullshit. Hard to take anything in. Must be for kids

I like this series If its too fast you can do like the kid said and rewatch the parts you miss. It is kinda technical so i missed some of the procecces and had to go back but i found it facinating and it helped me fill in some gaps in something I was thinking about

was really interested in the subjects but the instruction is not based on how many people learn. It is a crash course for geniuses or it is a nice refresher for people who took Chem in high school. I got into commerce and so am not incapable of learning but this is over the top and only a select group will walk away learning anything of substance. Every teacher needs to understand not everyone learns the same way. Those are the best teachers

Not sure this is a good way to teach (learning subject), more like a fast way to tell people what "I" know about the subject. ("I" being the narator). For someone already studying that subject, must be intertaning, fun and good reminder of what they have learned. I'm not at school, still i consider myself intelligent, and love science documentaries so muchs! Science becoming a passion. Watch about 300 of them on this site, This is one of the few doc.
I did not liked.

Maybe using those fast 12 minutes to explain a "specific" thing like ex.: "octet rules", i would of learn one thing at least; how octet rules works :D

I might seem unintelligent in my comentaries, but i know my brain is able to assimilate enough information to build my own theories and believes witch might be more accurate then the one already existing (what you learn in school)

Hear, I'm living in a french country with french speaking people, but still I was able to somehow learn English without anyone teaching me how, just by listening reading watching. That guy could of teach me more in that 12min, just by doing a simple bio experiment and explaining what happened. :d

Sorry for my opinion :D
p.s.: my first post... and a bad commentarie :S
don't be cruel with me

I love this series! I personally don't think it goes too fast, but then again I talk a lot and can really get going myself.... but I do find it completely entertaining and accurate -- the best combo, which for some reason always makes me brain-crush on the presenters....anyway....


I am a biologist who has physicist (and chemist) envy! (to quote Richard Dawkins) I think it's because I find biological concepts and theories fluff in comparison. I know there are more difficult subjects than others in bio (genetics vs. ecology) but they are all intertwined and what makes them difficult is the amount of physical science involved (i.e. the amount of reliance on the laws and theories that make biology work at that level) -- the actual biological concepts are pretty obvious (intuitive as you said).

I asked a chemistry professor what the difference was between those in biology and those in chemistry, and she said it was about being able to think abstractly. Biology is easy because you just need to know a few basics and look around you for examples. The physical sciences require you to really think outside the box of what we see and feel to understand what we see and feel (did that make sense??? see, this is why I am a biologist! lol) -- the idea that the toughest object on earth is made up of stuff that never touches -- you don't get that in bio! lol -- but I LOVE quantum physics and am trying to learn as much as I can.... even though it hurts my brain....

Better than the history series but, still a little hyper and rushed. That's the whole point though I think, thats why they called it crash course. They did a great job explaining hydrogen bonding, covalent and ionic bonding, and the nature of carbon in organic chemistry- very important stuff if you hope to understand bio-chemistry, which is a huge part of biology. I am not sure that I agree that chemistry is one level of complexity lower than biology but, I am a chemist so that is to be expected I suppose. Really the two are apples and oranges so to speak, one is just as complex as the other in different ways. Chemistry is much less intuitive than biology for instance. That said one must know some bio-chem to understand biology yet one need know nothing of biology to understand chemistry, so in that respect I suppose it is a more inclusive field. Chemistry is very inclusive of physics so I suppose in an indirect way physics is also part of biology. I guess it is a pretty demanding field when you really think about it, it makes me think even more highly of people like Richard dawkins.

Woooot! Crash Course rocks hard! Lovin it!
