      Neil is as important as the prof, simply because he puts the thoughts into physical reality, and as he has been doing this for a few years the skill and thought is great, and equal in the education of any of the students, who after all have to have practical application of chemistry to grasp the concepts, and to see just how and why things act like they do, both in theory, and that theory and practise agree. Otherwise this is not Chemistry, but Philosophy, where there is no actual confirmation, other than belief, that the conjectures are correct.

    • @Christopher.Marshall
      @Christopher.Marshall 8 หลายเดือนก่อน +2

      ​@Lolwutdesu9000 many professors that are PIs stop doing experiments and bench chemistry once they start their own research group. They focus on other things like keeping up with the modern chemistry literature and grant writing. Their lab skills atrophy, but often they are very well read in the literature, which is necessary to be a great chemist.

    I worked as a technician and am always surprised how under recognized the profession is.

In space, technicians would be extremely valuable as well, there's a way larger pool to choose from then just university grads.

    I saw this and decided had to watch it. My dad is a retired chemistry instructor, I have always been into electronics. I'm taking a TIG welding class this spring it's interesting how much chemistry and electronics are involved in welding. They use tungsten in TIG because high melting point and it conducts decently. It used to seem strange to me people talked about AC VS DC and different polarity for welding I didn't see as far as electrically why it mattered, but whatever is positive in DC has more heat put into it.
    Aluminum they use AC the negative tip cycle welds the aluminum and the positive cycle cleans the oxide off but also melts the tungsten. Stainless is also interesting as have to be careful with the heat or will burn out the chrome. Even the filler materials are different to add cleaning, help with welding overhead, etc. It would be cool see like a mini playlist of chemistry of welding.

    The principal ore of tungsten, (scheelite) is calcium tungstate and it is fluorescent blue-white under short-wave UV light, which is one of the methods of prospecting for it. Scheelite is dense and can be panned from stream gravels like gold, in many places where granites are present (e.g. Cornwall, UK) but it is white and looks like feldspar, so the UV lamp is essential.

I am commenting now about the statement that things usually get smaller when you burn them. I frequently do an experiment with my 13 year old students when we burn iron wool and it gets heavier, so things don't get smaller when you burn them but get bigger!

    12:00 That is SO COOL, my hypothesis for why the wire formed those wavy lines of oxide is: electricity is a wave of electrons [Watch electricity hit a fork in the road TH-cam Video](whether flowing, or vibrating, depending on current type), and as the wave peaks and valleys with increasing amplitude through the wire it will heat/react differently or more with the air in places where the electricity peaks or valleys. A similar thing was probably happening when the voltage was increased slowly as well and i think that I could even see it on the video, but the waves were given time to spread out slowly instead of making extreme highs and lows right away.
    Wish i could do research like this instead of jobs, but i get to handle tungsten, molybdenum, and even cooler+rarer metals all the time so its pretty awesome

      It would be confusing if the Norsemen would use 'tungsten'. "Sven: We figured out that those heavy stones had some heavystone ore, but did you calculate how much heavystone was in the heavy stones?"
