    I love that Wikipedia has already been updated (with sources cited) to reflect this information. Thanks for paying it forward, whoever you are!

    I like how the Professor just talking about a manuscript can be both informative and entertaining. A sign of a great educator :)

    Great video!! and here is another interesting FACT:
    Osmiridium a natural alloy of Os-Ir was very popular in the early 1930's because it was used mainly as the tip of the fountain pen nibs due to the incredible strength and density of the alloy. The tip was just at the end of the nib which was usually made of gold.

    True fact: he used copy & paste because his first suggestions for the two elements were "Smithson-Womanizerium" and "Tennantum-Longdongium".
    Great videos by the way.

    Iridium and Osmium are my favourite metal elements!
    I hope someday I would be able to buy a relative good amount of them!
    Nice video Brady, this one I loved it!

    Should those archives be handled with gloved hands in order to prevent body oils from eventually ruining the papers? Great vid.

    Osmium (heaviest metal) -> Os -> Osbourne -> Ozzy Osbourne (godfather of heavy metal). I know it's not related, but I always liked this.

    Please do not take offense to this comment, but I think I may have caught the Professor making a little mistake, or he may know something I don't, which is quite possible. Anyway, to the point, in this video Professor Poliakoff states that osmium has the highest melting point of any metal. And as far as I know this title belongs to tungsten, Please correct me if I'm wrong.

    That's a real shame at the end there. But I imagine it's incredibly common. I find it interesting to think about if someone later made the same or similar discovery. The latest video from RCSuperPowers ("J-20: Why?") actually has some interesting dialog on that.

  • @endimion17

    What I really like about profesor Poliakoff is his boyish fascination with things most people would think are ridiculous. Sadly, even most professors.
    I think his students are lucky to have a chance to be able to listen to his lectures.
    This video is great, it sorts of gives goosebumps. It's a true homage to a scientist.

    I hope Google digitizes archives like this!

    @teavea10 most likely, it could also be the cream pressure required to make it, also it coils be a slight modification to heat and atom bonds that causes them to be close.

  • @kght222
    @kght222 13 років тому

    @deadlock361 gold and mercury are heavier if that is what you mean, but density is based on the molecule more than the atom. (even titanium is heavier, its the molecule that makes it light).

  • @Z1BABOUINOS

    @itedin
    In this case, the element would be ozoum or ozeium (from the verb ozo /όζω. ozei means "IT smells terrible"). Since it is oSMium, it comes from osmee /οσμή (the word from 'smell'). The route of the two words is the same, but not the meaning. It would be more precisely descriptive if it was named ozeium.

  • @oisiaa
    @oisiaa 13 років тому

    @hoboX10 I think Osmium is the most dense element. He probably got confused.

    @Kyle11493 I'm aware of that, but it seems to always be used in small amounts, while I know it is very abundant.
    More recently I have discovered that nickel can harden steel, but I don't think it does as well as titanium, palladium, scandium, or vanadium.
    So basically it just seems to be a metal with no major purpose to offset its high supply.

  • @ragnkja
    @ragnkja 12 років тому

    That sounds like a possible name for element 119, since heavy elements with odd atomic numbers apparently tend to be less stable than those with even atomic numbers (elements 114 and 116 have been named, 113 and 115 haven't), and also because it would be beneath what may well be the least stable naturally occurring element in the periodic table.

    @hla27b Microsoft Access (an option for MS Office) is largely based on the principals used in index cards; Cross referencing different data in varied combination, unique Key identifiers, restricted data field input.
    One could say index cards are the grand daddy of today's inline data bases.

    Is there a reason why iridium and osmium occur together in nature with platinum? Is it related to their being the three densest elements?

    ουσία in Greek means essence which is a synonym for smell. It's pronounced /oozia/, ooze-e-ah. The -mium is chemical element naming tradition which is a Latin thing concerned with the definite article of a word. Mystery solved -- somebody alert the professor.

    Those were the days when one could discover an element with tangible properties. What name can be given to a modern element of which a half-dozen atoms, created artifically, last for a fraction of a second inside an accelerator? No wonder they have to name them after famous scientists.
