  • LOL, funny.

    Yr timeline is a little off -- oxygen was actually first isolated by Scheele in 1771 and Priestley in 1774.

    What happened in 1783 was, Lavoisier showed how combustion -- like, burning and explosions, but also rusting and other forms of "combustion" -- worked.

    Before that point, the dominant theory was that combustible stuff all contained... a combustible *thing*, which was called "terra pinguis" or "phlogiston".
    Basically, the theory was that once you burned the phlogiston away, stuff would stop burning.
    Makes sense right?

    Well... the first problem with the phlogiston theory is... lots of stuff weighs *more* after combustion (e. g., metal oxides weigh more than the pure metals).
    Also, if you cut off air supply, stuff that usually burns... won't burn anymore. If phlogiston were a thing, this wouldn't make sense.

    In 1783, Lavoisier put all the pieces together and figured out that the **already recently discovered** element of oxygen was being consumed when stuff burned. So, no more phlogiston theory -- he figured out that combustion was actually stuff combining with oxygen.

    What's with these questions lately btw? First carbon dating, now this -- Are you studying for some sort of advanced fire science certification, or sth?

  • But how do you know that they discovered it back then if they couldn't announce their discovery through the internet or television?

  • we hadn't evolved the ability to breathe oxygen prior to 1783, so we didn't need to discover it.
    trust me, I have a theoretical degree in physics.

  • lel XD Just because they discovered what chemical made it to help us breathe. Doesn't mean we couldn't before then since the chemical still existed. :P

  • we didn't the Illuminati forced us to breathe it and now we are dependent on it. it was a conspiracy to make space travel to mars harder as there is no oxygen there.
