    I wish this had been around when I was in high school. It's truly excellent how you cover every subject in depth, without any assumption of previous knowledge, and without any talking down to the audience. It seems accessible to anyone, but even if you're totally familiar with the theories, seeing the built apparatuses and having the principles explained so clearly and visually is such excellent viewing. Really inspiring, thank you.

      Sadly, we are probably not going to see the teaching style change in our lifetimes, but for the future students, this is the way of learning. It might sound a bit too idealistic, but I think we're going in a great direction when it comes to teaching. I've always hated history and I never really understood physics and chemistry, even doing well in school, but now that I'm over 30 and getting into those topics I can see how much time and effort was wasted with stupid and outdated teaching methods. Now I'm learning math, chemistry, physics, history, even philosophy and biology - all through the Internet, all through people like our precious presenter here (which I don't even know the name of!), just having fun learning stuff and getting to know the universe I live in on a really deep level.
      So yeah, I agree, if I I was born in the last 10-20 years insted, I would be a much better person overall and I would understand the world a lot better. This isn't just a crazy science channel, this is the future of humanity in the making.
      I know that 90% of the kids I went to school with would be interested in stuff like this. We, as a spiecies, have to stop teaching boring formulas, we need a goal and presentations like this one to lit the fire under people, to get them questioning the universe and pushing humanity forward.
      These are interesting times at least, we truly are on the brink of a revolution, even if we don't get to fusiuon power in 5 years.

      Electrons are not particles. That’s easy to prove. Also the man who discovered electrons said it’s not a particle, JJ Thompson It’s a field. It’s apart of the dielectric which is 1 with magnetism. JJ Thompson said an electron is 1 unit of dielectricity. This is not my opinion. This is fact. Charles proteus Steinmetz has a great book. Electrical discharges waves and impulses. It’s a must. Especially if you want to understand this more. Also theoria apophasis on TH-cam. He’s the man for magnetism. Many free books of his that are great. Charles proteus Steinmetz work backs it all up.

You are correct that some of these particles, particularly photons and electron streams, exhibit wave-like properties. This is demonstrated by the concept of wave-particle duality.
      Things get wierd when you go into subatomic physics, and things like absolutes fly out the window.

    Great explanations for the physics involved. When I was about to graduate from college, I toured a few high schools to generate interest in physics as a potential major for the university. We brought along gas tubes, high voltage generators and explained how light was produced from electron orbit decay. We even brought alon some LN2 just for fun. It was rewarding to watch the students eyes light up when they understood the concepts. Watching this brought me back to those days over 30 years ago. Keep it up!

      There's so little heat capacity in a coke can that it will warm back up to room temperature pretty quickly. I suppose you'd need something to keep it cold right up to the discharge of the arc. Maybe contain the coil and can in a dewar containing liquid nitrogen, without immersing the can in it...

    Your description of the heating of the coil in your plasma pinching demonstration reminded me of a module I designed back in the '80s, commissioned by the JET (Joint European Torus) project at Culham, 20 miles or so up the road from here. I was then working as one half of a 2-man company.
    The module was called an I-squared-T integrator; its function was to monitor the magnitude of the current in the busbars feeding the torus electromagnets (using Hall effect sensors), and integrate the I^2 x time, with a trip level set to shut off the current before the busbars melted. The module allowed the computed value to decrease with time (allowing for the bars to cool between pulses).
