      The misconception about fire being a plasma is actually really common. It isn't plasma, but it isn't a solid, liquid or gas either. It's our visualisation of a chemical reaction. It might look like something, because it is constantly there. We can see it, we can feel the warmth, we can hear the crackling of whatever is burning and smell it too. But think about it, when the fuel is gone, so is the fire. You can't see what fuels the flamethrower, but it's not like you're creating fire out of nothing. Fire is just a prolonged case of combustion. A chemical reaction.

    Public school science textbooks should use your explanation of electrons and an explanation for electron cloud distribution which it doesn't even mention which makes students believe somehow electrons just magically spin around atoms. Plus there's the Bill Nye video where iirc I think he claims electrons can be like miles away from its atom. Which perhaps is either outright wrong or only showing one specific scenario.

    Those professors that i will forever remember from my academic world, are guys like this. They don't go (only) by formulas, by theorizing around things. That's easy for guys that have good memory. They go much deep into a world where they can keep things interesting for the students and make them think much by themselves about what they are explaining. I've found that this itself is a form of art. The art to teaching, that only a few can master. Sure you have so many teachers and professors and whatever. But for me the real ones, are guys like this. Congrats and keep up with this videos.

    hi David, i thoight it was recognised that there were 5 states (or phases) of matter. going opposite tfrom the hot end down to the cold end you end up with the bose - einstien condensate. although admittedly the four you mentioned are regarded as natural states and the 5th is man made.

    Thank you for this excellent video, Prof. Ruzic.

The argon still argon? Or does it become some sort of "matter soup" of electrons and nuclei floating about?

    I hate to disagree with the great Professor, but it is not the 4th phase of matter. Because it is simply heated "gas", and Plasma is just that, and nothing else like Plasma - heated gas. Now he is correct saying 99% of the material in the universe is Plasma - stars, suns. In our solar system the sun makes up 99% of the material, the other planets 1%.But I loved how he was writing backwards on the clear board. Sorry, but I think it is cool. And I enjoyed the video.

  • @sethnotes
    @sethnotes 3 ปีที่แล้ว

    I'm confused about something. If I understand correctly (and I may not) a plasma occurs when atoms are heated until electrons are ripped away from the nuclei. So, I think it's like you have a haze of electrons and nuclei. If so, is there a difference between plasma generated by heating hydrogen and plasma generated by heating oxygen? In both cases (again, assuming I'm right), the plasma would just be electrons and nuclei separated from each other. So, would there be a difference? If so, what would that difference be? Likewise, if you heat oxygen until it's a plasma and then cool it, does it go back to oxygen gas? Or do different atoms form?

  • @wesamhashish9

    It is a bit more accurate to think of the Plasma as a dielectric of separated charge - the 'Solar Wind' is a Dielectric Wind from the Sun's surface. It also represents 'Charge Separation' in Space that the present cosmological model doesn't recognize, unfortunately for the reputation(s) of the scientist agreeing to such 'democratic science' ...

      @ristopaasivirta9770 4 ปีที่แล้ว +2

      Tesla intended to harvest energy from cosmic rays. He called this energy "radiant energy".
      "I will tell you in the most general way," he said. "The cosmic ray ionizes the air, setting free many charges-ions and electrons. These charges are captured in a condenser which is made to discharge through the circuit of the motor." --- "The attractive features of the Cosmic rays is their constancy. They shower down on us throughout the whole 24 hours, and if a plant is developed to use their power it will not require devices for storing energy as would be necessary with devices using wind, tide or sunlight."
      There is an ambiguity and confusion with the Wardenclyffe tower that was his intention of broadcasting electricity across the globe by ionizing the atmosphere. So in essence people would have gained access to "free electricity" everywhere around the globe, but that electricity would have been manufactured somewhere by conventional means and then just broadcasted.
