For all his obvious intelligence, knowledge, and skill ... his true talent is teaching. This is a subject most people only understand in the abstract. He explains it in a way my 8 year old can grasp. And does it in 9 minutes. Amazing. Thank You Professor.
@@onetwothree4148 there's tons of youtube videos and other things on the internet that all affect my time management, so I blame something other than just youtube, it's a whole culture of websites that all suck away my time
All through highschool, I was excited to learn about plasma, but every time I asked about it they were like, "yeah we're not covering that." It's a blessing to have free, high quality education like this.
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.
This Professor is really amazing . It is very easy understand each and every concept which he teaches. I request you to continue this as much as possible. Thank you!!!
Professor your videos are amazing. Very easy to understand and full of great knowledge. I wish I had you in my college, I would have gained better grades😉 Thanks for uploading
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. Sorry if this is too long :)
@@samsawesomeminecraft well, yes. Though, fire isn't a type or subset of combustion, it's just combustion when it's happening for a longer period of time. And yes, it emits light and warmth.
Isn’t it interesting that people like Brian Cox and NDT will wax lyrical for hours about dark matter, muons, leptons, quarks, etc. But will never even utter the word plasma. “Interstellar dust and gas…” No, it’s plasma. Thank you for this very clear introduction.
can the plasma reconfigure itself and create other elements than those initially included in the gas? if so, how to control this process and what elements can be created from plasma?
this guy so cool. Always been a scientist but not in this field. Saw one the other day now i am hookt. And i've learned somethings. Such as radioactivity does not come from radioactive things or sources. He said neutrons cause radiation. And i blieve him. Why would he lie and since this is science easy enough to verify. Thank you for the knowledge from this and the other video you made.
Thank you for this excellent video, Prof. Ruzic. I'm left with 1 naive question: If a gas, as in your hydrogen or argon examples, is pushed into a plasma state (where the electron is ripped away) ... is that hydrogen still hydrogen? The argon still argon? Or does it become some sort of "matter soup" of electrons and nuclei floating about?
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?
Have you considered how we went from earth, wind, water, and fire to solid, liquid, and gas? After-all LEDs are solids that emit light, lava is a liquid that emits light, and fire is a gas that emits light. There’s a clear case that luminescence is a property of matter like electric charge and magnetism. The plasma ball is compelling but, you can run a high voltage current through a piece of wood and see that it only runs through a narrow circuitous path. If plasma is a different state of matter then it seems we would have to add two more states for luminescent solids and liquids. Would you agree?
Does anyone know what was going on with the very last experiment? How do a radio frequency and a coil produce a plasma? And why is a radio wave considered DC?
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.
Sir, your lectures are so great. Thank you! After only a few weeks, I think I'm a genius. There are obviously 5 states of matter. The fifth is actually the first, preceding solids. It's the"programmable", empty framework offering location options for the other forms of matter/antimatter. I guess space? Is that matter too? If there is a quantity of it, it must be a form of matter too, right?
In a sense, yes. CME's are from the bending, breaking and then reformation of magnetic field lines in the sun's corona. When they break, they fling (eject) charged particles that were entrained within those writhing field lines. Imagine bending a piece of dry spaghetti to the point where it breaks. You always get a piece that flings off....
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. regards richard.
I weld for a living. with tig we mostly use argon to shield the plasma from the atmosphere. In my world, we call it the welding arc. When it comes to welding aluminum, we can adjust the focus of the arc by adjusting the hertz. When welding steel we adjust the focus using amperage and the distance between the electrodes.
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.
@@MartialBachoffner re: " what I want to know is how it starts. " Via the Triboelectric effect - which involves the falling of ice particles (as part of precip). Notice, low level tropical rain storms DO NOT produce lightning. They do not have precip appearing above the 'ice line' (freezing line) in the cumulonimbus producing rain cloud.

I had a chemistry teacher that said, “it’s rare and not that important.”
@@atomicsmithexactly 😂 my chemistry teacher also 😂. He said it’s not commonly found so it’s not important 😭😂
This is the professor’s best video yet. Plasma is def something he spent time thinking about. Love the demos too.
Really enjoyed the demonstrations, especially the one with the magnet. Made it simple to understand. Thank you.

awesome, worth watching n gaining knowledge.
Really nice discussion. Clear and cogent. Thanks.
So a Flamethrower is technically a plasma cannon.
Anything that reaches a certain temp is a plasma. Thats solid, liquid or gas.

part with 4 elements was so interesting !
Great video. Learned so much. Replace the marker.

Does the gas you use determine the color of the plasma and the different type of plasmas?
this channel is awesome.
Amazing. Thank You, sir!
Nice sir
So it's just vapour or is it any gas that can be turned into plasma
can the plasma reconfigure itself and create other elements than those initially included in the gas? if so, how to control this process and what elements can be created from plasma?
What is an electron distribution cloud?

So you can heat an ice cube till it turns to gas, keep heating then it turns to invisible energy?
THANK YOU for FINALLY making sense of what a plasma is!! :)
does magnets would affect fire (plasma)?
When will we "need to know" this?

One way to use modulated plasma is plasma tweeters. You can make sound by modulating plasma using an AC audio current...
So fascinating! Love this channel! Interesting that the greeks got all 4 states of matter kinda right.

Isnt it possible to creat power using it
Hah, interesting. I didn't know that it makes up 99% of the stuff in the universe.
Neither do the dArK mAtTeR scientists.
Does plasma rust?
So is water the molecule becoming a plasma or is the hydrogen and oxygen becoming their own plasma states?
What software and hardware is in his presentations? I don't think it's simple glass, because the image would be reversed.
Wow I learned a lot from that lesson, great job ;-)
I like the end. awesome.

his ability to write backwards is astonishing.
realomon that’s all I could focus on at first lol. I think he’s writing forward and the video is flipped vertically.
It's a mirrored presentation. Notice his wedding ring is on what appears to be his right hand.
LMAO
Amazing how many people don't know what mirrors do. 😜
His ability to get an adhd kid to understand more complex ideas than this is as astonishing
just curious, is he writing from the back of the glass?
What is the difference between plasma and fire? This wasn't taught when I was in high school and it's not taught in my son's high school.
If this was my science teacher then I would want to be a science major.
How about cold plasmas?
What about cold fusion???
I like your videos! Wow. Please continue to do more. But clouds are not water vapor, but water droplets (liquid). Water Vapor is transparent. 😜
Are you saying boiled water is a liquid, because it isn't transparent?
@@onetwothree4148 boiled water is water vapor. However clouds are made of water mini droplets (liquid) or ice crystals (solid), not vapor.
@@michaelmardini346 why don't they fall when they become liquid?
Is Only heat energy can produce the plasma , any other energies can produce plasma?
Ionization?

The 12 dislikes are elementary school teachers who still say it’s 3 states
what about the neutrons
Neutral.
free neutrons decay after some 15mins into a proton, an electron _(and an anti e- neutrino)_
So is it plasma in a nuclear explosion that makes the electromagnetic pulse, or is something else coming into play?
07:02 Is this like a mini version of a Coronal Mass Ejection?
In a sense, yes. CME's are from the bending, breaking and then reformation of magnetic field lines in the sun's corona.

There are 5 states of matter, with BE condensate, but you surely know that sir. BE condensate is just so rare we can neglect.
