If you are an Indian using the Word 'India' attached to something that is watched globally, be careful and fully aware of it's Use. Do NOT use that Word casually to generate a Forced Joke.Whatever we speak stays permanently on the Social Media. So use Words carefully. I am an Indian, having already completed my Masters in Computer Science. Now I am chasing Masters in Physics and nowhere had I an Experience where the Teachers were over-Cautious and hyper-panicked.

In Our school they were not worried about our fingers instead they used to say - don't touch that vernier caliper or you'll break it and then you'll have to pay for it
while studying in college I had seen this apparatus in book and was always confused to imagine how it works and today saw cathode ray tube (& electron flow) demonstration live. Now I'm 37..wish we had got such a Good Teacher 😥
Damn! That's literally a perfect teacher there! I've always wanted to be taught by someone who teaches well at the same time who doesn't make the class too boring 😭 perfect.
Indian schools don't show any experiments. They just feed us theory. It is really hard to study that way. These students are very lucky, they get to see live experiments :)
Okay ,let's not combine the whole country to blame upon because exceptions are always there It could be the same in other countries as well . And I highly appreciate teachers who actually decide to make learning interesting irrespective of nationality,race, caste,religion,creed or gender
@@rakhibepari exception can't be an example I also respect those few teachers of the subcontinens who makes science interesting to the students but in most of the case most of the teacher there has intention to force students to memorize everything that's not how science that's not how education system works education should be enjoyable and should be experienced mostly in case of science thus the educational system of subcontinent should be changed they should focus on the experimental education system and they should stop force students to memorize everything without understanding it
While I was trying to understand this concept on how electrons were discovered, from the theory which was provided by my school teacher, I didn’t understand anything, really! But, when I saw you doing it practically, things were made more clear. So, a big big big big thanks to u
@@kineticballs77 sorry but that was not supposed to be a compliment indians students don't have much practical knowledge many situations are tough to understand with just theoretical knowledge whereas here people focus on practical knowledge more than theoretical one
@@kineticballs77 this has nothing to do with it what they leant was not even what was NEEDED there may be some good students who understand the things but indian's method is very bad for many students who can't understand without seeing the things themselves and what you are say may be true indians are better than foreigners in maths but there isn't any need to calculate when they got calculator they focus on finance and pratical maths while what we study is completely different
guys he's not a school teaches he's a professor in a college be proud of ur teachers our teachers in India teach us foreign college level chemistry.....my teacher also showed me cathode Ray tube in the lab....if u also want to see just ask ur teacher to show u from the lab :)
I’m glad your experience in India has been good. I’m very ignorant of educational practices in India. I’m not a professor though. The students in this video are 15 year olds, many of whom didn’t go to college after high school.
And here I was wasting my time in reading the same topic again and again and trying to understand how electrons were discovered..... We need a teacher like him
@@goldenlegend7200 yess,your school must do these activities in your dreams,that's why your are asking from others!and must remember to be in your limit!!
I wish that I had a teacher like him :) ...such a fun and interactive class it was :) .... India needs teacher like him who can demonstrate the practical approach to all the stuff written in the textbooks
Can you explain how electron beam is being generated in the tube by Tesla Coil if there is no potential difference between cathode and anode in the tube??
eleggance The Tesla coil generates a high potential . The electrode near the coil has a high potential and the one far is at approx 0 potential . So the electrons flow .
The other end of the Crookes should have been grounded for best effect. He is relying on the leakage of the current through the wood stand and into the air. That is why the green beam is not that sharp and also has a vertical line where the glass standoff is in the middle - the electrons are leaking down the glass standoff and into wood stand. BTW - safety tip, keep that Tesla coil away from those gas jets.
The BD 10 wand that he claims to be a tesla coil is actually a device based on an oudin coil and does not have spinning magnets inside of it. Had it been a tesla coil it still would not have had any moving parts inside.
Exactly. The buzzing sound is the mechanical interrupter that pulses the current to a little Tesla (Oudin) coil and out comes high frequency high voltage. Otherwise, great presentation!
re: "and does not have spinning magnets inside of it." Do you know what a motor is, how it operates? A motor is used inside the 'wand' to drive the mechanical interrupter at a very high rate ...
@@uploadJ Yes I am very aware of what a motor is. That is irrelevant because this device does not contain one. I personally own and have worked on multiple of these. There are zero moving parts, the sound it makes is when the electricity arcs across the spark gap preventing the user from making direct contact with the AC source it is plugged into.
Saliha Salam If the pressure is high( due to larger number of gas molecules) we’d have to apply a high voltage. But if a few molecules of gas are to be escaped pressure will be low and we’d have to apply a relatively less amount of voltage in order to observe the phenomena... (by lowering the pressure means the number of gas molecules present are lower and thus for less molecules less amount of voltage will be enough)
@@internetuser9279 This tube is not acting like a typical load. Here the main thing to observe is the passage of electrons from one electrode to another and this phenomenon doesn't need current to flow back to its source unlike other loads Hope this will help:)
I think that was a wonderful teaching thing to do. If we all were given such coolness in elementary we'd be a much more advanced species. On that note, may i open your mind professor to explore a different perspective. Your science was correct until the light from battery vs tube.
i'm a little bit jealous, i wish i'd have a teacher like that
I also wish
@@educationalschool1215 me too
Ya.. Me to
NO bro !! Everyone loves their teachers , if yoy say like that. You probably insult you teachers
Me too
Meanwhile in India - Don't touch that vernier caliper, it's too dangerous to touch. You will probably cut your finger
Lol bro same with me. We have a various materials at our lab but they
Always told not to go near them as you will broke it lol.
lmao true

hello i am from india
Our teacher read straight through the entire history of the atom in one class, and just told us to learn it🙃🙃🙃
SAME
Happened today to me too! And then proceeded to do electricity in magnetism in the space of an hour! O_O
I think only Curious and enthusiastic teacher should deserve to teach Science
Same here
U from?

That's why indian students are better in every way cause they learned it the hard way.

you are a great teacher!!!!!! I also want a teacher like you who explain us practically like that
Nice way of teaching, Sir.
Great teaching! Thank you, teacher!
Telugu! :)
I too a Tamilian studying CBSE class 10.
You made it crystal clear !
Thank you
Beautiful class. Thanks for upload it on youtube!
And what you can't see kids, are the X-rays, but i'm sure you won't have to worry about that lol.
Thank You Sir. Keep safe everyone. God Bless Us All Always.
Such a great teacher 😊😊🙏🙏
That's nice 🙂 you're really a great teacher.... I really want a teacher like you 🙂🙂
The professor is great!
Thanks for this amazing demonstration ❣️❣️❣️

Everyone need such teacher
This is AWESOME.
We need teachers like him, guys who still teach us in the perfect way when pur pre-school teachers told us 🤍👏🏼
Excellent
this is amazing
So good, wish I had a teacher like that😔
Good explanation
a very nice video !!!
I'd like to watch Ur next video Sir But I like your way to teach them ......it seemed like enjoyment you're doing well...🙃
great vid!
Gas discharge phenomena, the discovery of the electron, etc. sowed the seeds of modern physics.
I think our country has burning need of education system like this.
Already had.. Not every where.... But may be it take some decades to spread all over
I wish that I had a teacher like him :) ...such a fun and interactive class it was :) .... India needs teacher like him who can demonstrate the practical approach to all the stuff written in the textbooks
We already have many!
I have never seen a teacher like him he the cool teacher in my world
Amazing 😍

Good video 💯

Amazing
sir nice explained
If you ever see him again tell him he’s famous
Thank you
ඔබට ස්තුතියි ගුරුතුමනි
O god. I was really wanna this experiment. But so sad there is no sources in my school 🏫. But yeah when I watched this video I'm very happy 😊.
Thanki sir love from india
VERY nice 😀😀😀👌
Nice teacher
This guy's vocal pitch is on point @2:40
Ke$ha, can you believe this he's singin' a Ke$ha song. Why isn't my teacher this cool?
Thanks a lot
i wish if i had such practical explanations in my school lol
Why you connect only one terminal to a electrode
thanks
Thankyou sir
When he says- oooeeoeeeoeee oee WHY WHY WHY WHY!! OYEOOOEOE 😂😂🤣🤣
W Crook discovered Cathod rays and named them electron.
It is effecting the magnetic because it has no electricity and when you are passing electricity from instrument it effects
Thankyou
Was he humming a Kesha song In between?
so they new about electricity and have some way to generate courant before even discovering the electron ?
Why is the light in the Crooks tube green?
Woowww very good
How many voltage are required?
10000W approx
Hi sir from where we can bay these apparatus.
thank you1\!
What is the relation between pressure of gass inside the tube and the applied voltage???plz help if anyone has idae...😢😢

Where's anode and cathode connection with high voltage
2:41 in India its substituted by naagin tune
This is difference between foreign they tell through experiment
That's how science should be taught.
Sir why this green light is only looking
Watching dec.2021
Who is the singing this strange music?
So sad that we dont have one ..And any Experiments on our lap..
Which is product use ..please share me product used name this ...is
If you Google “high frequency generator” you’ll see the voltage source. And then I have a crooke’s tube with a screen inside and a neodymium magnet.
🔥🔥🔥
wow
This video alone of 6 min can expose the education system of india
