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.

@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 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.

I love when I recognize a property of one of these elements when you show something like that thinned wire at 12:55. My brain just went "Yeah that's like how light bulbs get dark over time, because the tungsten evaporates as it heats up, then it applies a thin coating on the inside of the bulb."

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.

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 KZbin 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
