I've always appreciated how much the professor recognizes Neil's skill and work and how much he tries to get everyone else to understand how important he is.

[@sparky6086]

Neil is to Professor Martyn, as Jim is to Marlin Perkins on "Wild Kingdom".

[@theodionne9370]

I really wish more professors were exactly like this. Dr. Poliakoff is one of a kind :))

[@SeanBZA]

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.

[@EnmaDarei]

[@Lolwutdesu9000]

In my time during research, I started to believe that technicians had a better understanding of chemistry than some of the doctors/professors. Difference between knowledge and experience, I guess!

[@Christopher.Marshall]

​@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.

[@SuiLagadema]

I don't know why but, even if I've never heard Neil speak, I picture him as a child in a candy store when he does experiments, like, on the outside, he looks completely professional and composed, but on the inside, there's this kid that's super jumping with joy every time he gets to do experiments.

[@clivematthews95]

Many thanks Professor Martyn and Neil and Brady for a truly fascinating exploration of tungsten’s properties. The demonstrations were magnificent. I had to laugh out load when the professor commented that after a year the university’s suppliers were unable to supply powdered tungsten but when ordered on Amazon it arrived within a couple of days. Surely herein lies a tale!

Nice to see a call out for Neil for the work he did in helping make this video. All to often, lab techs are overlooked but the knowledge and experience they possess from years of working in the labs makes them an invaluable resource that should be appreciated much more. Great video too. 👍

[@jeffspaulding9834]

You guys have always done a good job of showing Neil as a critical member of your team. That's one of the things I like about this channel.

[@flamencoprof]

Thanks for the shout-out to technicians. It made me realise that probably why I am watching this is because at school in the mid-sixties I was a lab monitor for a while, then my first job was as a Medical Laboratory Technologist, where we did the tests, and differentiated ourselves from the Technicians, who maintained the equipment, then later worked for decades as a Telephone Exchange Technician, which I enjoyed. Always Safety First.

[@VincentGroenewold]

I worked as a technician and am always surprised how under recognized the profession is. That said, there is a huge variation in what technicians do and are able to do, I was basically a postdoc working as a technician. :) Just was never interested in the higher position as I wanted to work in science all my life (didn't happen in the end, but long enough). In space, technicians would be extremely valuable as well, there's a way larger pool to choose from then just university grads.

Lovely that Technicians finally get recognised for their work and expertise, always working hard in the background with little acknowledgment. They do play an important role in supporting industry and institutions such as medical facilities and educational establishments, looking forward to visiting the Science museum if I ever get to London!

[@AnonNopleb]

Neil is a real hero. I am very impressed how he did not give up those experiments. It sometimes takes quite a lot of experience and intuition to make an experiment work if it doesn't, which parameters to change and probably most importantly, when to decide to stop, a.k.a "that's as good as it gets."

[@maolcogi]

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." I'm not a scientist, and only did a few chemistry courses in college, but man do I love this stuff! :D

[@network_king]

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 thinning of the tungsten wire is a trick I've seen before, when Ben at Applied Science (I think it was him) was making gecko tape.

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.

[@gregorymalchuk272]

[@joseywales6168]

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
