    Hey guys, for chemistry I have to do a project about th 10 most important chemical discoveries of the 20th century and write a page of moral/ethic stuff on the top 5 :p I was just curious if there are any science guys out there interested in this stuff. SO far I have a list of 9:
    (not in Order)
    Penicillin
    Fuel
    Rubber /Synthetic Fibres
    Batteries
    Insulin
    Nuclear Fision
    TV
    Pesticides
    DNA

    Anyone have any cool uique ideas for a 10th?

    Thanks,
    Baker

    Important -YES 20th Century unfortunately not, he did all his experiment stuff un like 1752. But thanks for the suggestions anyways.
    EDIT: I was thinking morphine but the teacher doesn't want too much medical stuff (lemme know if you have a really outstanding one though :p)
    Thanks

    TV is a chemical discovery?

    Anyways, I suggest Teflon.
     
  5. How DO they get it to stick to the pan?

    Are you sure DNA was 20th century? I'm pretty sure I learned that they had been doing experiments and such as early as the 1400's

    she said I could talk about the chemical makeup of a computer or TV and what not. I was thinking Hydrocarbons but I'm having trouble finding when they were discovered.

    From what I've read it was initially discovered in about 1869 but was all developped and everything during the 1930's -

    How about Forensics (sp)?

    EDIT: The double -helix was discovered in 1953

    Alrifht a quick search tells me they were discovered around 1920! Thanks Sonorus. You guys can feel free to still throwdown suggestions or ideas/ opinions.

    Thanks alot guys!

    silicon chips - they are made of different "types" of silicon, n-type and p-type. N type silicon is silicon mixed with phosphorous, which has one more valence electron than silicon, creating a surplus of electrons. P type is silicon mixed with aluminum, which has one less electron than silicon, creating "holes" that attract electrons. When you put p type next to n type in a chip, a boundary layer forms between them where some of the electrons from the n type go over to the p type side. Then if you apply a negative current to the N type and positive to the p type, current flows. If you apply the current the other way around, current doesn't flow. This is called a diode. I kinda oversimplified it, so if you want to know more, look at the article on http://www.howstuffworks.com, its pretty good.
     
  13. Silicon Boobs! :D
     
  14. LSD

    Penicilin - pure biology
    Fuel - dude, oil has been known for thousands of years... Think oil lantern... Also, petrol was used before the 20th century, and could be had in drugstores. The first (experimental) cars had to get it from them. Be sure to write about the industrial production of petrol and diesel - that's more 20th century
    Rubber - older
    Insulin - biology/medical
    Nuclear fision - partly physics
    TV - :eyebrow:
    DNA - biology

    Plastics. Very important, used almost everywhere
    Some of the newer explosives that were used in the two world wars and afterwards. You could write about the moral/ethics side. (Gunpowder, nitro-glycerine, dynamite and TNT are older, look for newer ones)
    Napalm - same as above. Developed in WWII
    Do a search for the Chemistry Nobel prizes to come up with some more ideas

    How's about that? Early this year I saw a report with a professor here who invented "instant blood", in a powder form, and he complained about not getting money from the government for the researches... Now, he has no money, and his invention is stolen :spit:

    What about Viagra????

    All rich guys over 50 with 25 year old girlfriends I think thats a pretty important chemical discovery.

    Now that's better. It has more to do with biology, though. :p
