Storyline

Crash Course: Chemistry

Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff.

Chemistry can tell us how three tiny particles - the proton, neutron and electron - come together in trillions of combinations to form... everything.

We start out with one of the biggest ideas in chemistry ever - stuff is made from atoms. More specifically, we learn about the properties of the nucleus and why they are important to defining what an atom actually is.

A unit is the frequently arbitrary designation we have given to something to convey a definite magnitude of a physical quantity and every quantity can be expressed in terms of the seven base units that are contained in the international system of units.

Hank thinks this is a thrilling subject, and while you may not agree, it is a subject that is very important if you want to be a scientist and communicate with accuracy and precision with other scientists.

    One atom said to another I think I have lost an electron...the other said positive.. yes how did you know.

    (LOL) I got it.

    This is a great vid collection. One of the hardest things for students to get in chemistry, in my experience, is significant digits.There is actually a set of five rules you use to determine which digits are sig. but they just cover two in this vid, still its very informative. Sometimes you know which are sig. but you can't figure out how to represent that correctly in your final solution. They cover this trick as well, scientific notation is usually the answer. I guess because I have a degree in this field I am biased but, I think this is one of the best scientifically based vid. collections I have ever seen. For what it is worth I would recommend this to anyone interested in chemistry or physics.

    Chemistry Is Awesome!!

    I highly recommend subscribing to the youtube channel "SciShow", which is also done by Hank Green. His videos are universally entertaining and informative.

    Can't take this guy's voice. Super annoying.

    A neutron walks into a bar and say "How much for a Beer? barkeep" for you, no charge.

    A Higgs boson goes to church but they won’t let him in.

    But you can’t have Mass without me says the Higgs.

    Lol, some clever stuff in there but “What does DNA stand for” > LMAO

    lol i know i have been using that one.

    My teenager and I think it would be wonderful to absorb what Hank has to offer here, if only he would slow down enormously and deliver all this with consideration for the viewer. As it is only a cognitively competent used car salesman could follow him. This is not very dignified Hank.

    If you do manage to make a user-friendly version, please I form us so we can satisfactory our curiosity.

    Salute.

    Does this guy think he's hosting a game show or something? Good info, for sure, but it was difficult to absorb all of it from somebody who sounds like their impersonating Zap Brannigan. Just sayin'.

    I couldn't even make it through 20 seconds

  14. Autodidaction<SP?

    I found this a more pallitable presentation than any high school chem teacher ever bored me with . Thanks

  15. nia shrodinger

    so i was watching this because i was bad at chemistry in h.s. he was explaining protons neutrons and electrons and kinda said neutrons were boring and i thought, 'what if they had to do with gravity?'. i looked it up and nailed it! sup b*tchs -nia shrodinger

    Great job Hank (and obviously the whole team). Beautifully put and taught.

  17. Fabiola

    Hello!! How can I see the full documentary ?? someone to help me !!

  18. Patrick Smith

    Thank you. I feel a bit smarter now. I like your tidbits . Very helpful.

    Wow, what a fast talker...and I thought I blabbed a lot lol!!! Parts have been a wonderful review, and other parts new to me (particularly the math, I'm much more of a theory than numbers person). Thank you for sharing, I'll be back to watch it again, there's a lot of information here that I'd completely forgotten or just never had properly explained either through reading or course work. This would have been invaluable to me in high school, as well as to my daughter a few years ago. She did well but her teacher tended to go off on tangents and skipped a lot of foundational material. :)

    I enjoyed the intro, so will watch more of these videos. Hank obviously knows his chemistry, which makes it possible to explain it clearly.

    Most people in HS give up on chemistry because their teachers suck, because they didn't have a strong enough grasp on the material to explain it clearly.

    Some good info - but I felt the host was talking much too fast for me to follow some of it; feel like it could have been done in an interesting manner without the "nerd act". Punchlines were funny but not delivered this way.
