"As the cathode rays carry a charge of negative electricity, are deflected by an electrostatic force as if they were negatively electrified, and are acted on by a magnetic force in just the way in which this force would act on a negatively electrified body moving along the path of these rays, I can see no escape from the conclusion that they are charges of negative electricity carried by particles of matter."
-J. J. Thomson (Philosophical Magazine, 44, 293 (1897))

if schools taught us this way, we'd definitely be more interested
how school will taught
even they are not having such materials which are required to conduct the experiment
nakul and Kyushu nice English dumb ass
Sean Madden, C'mon, they clearly aren't native English speakers, you should be ashamed of yourself cause you seem like a native English speaker yet your grammar isn't that good.
So true
Sean Madden lol sean, u r so true. These idiots spoil english
Its crazy how recent some of these comments are despite the fact that this was posted more than 10 years ago
Yess
lmao watching after 12 years😂😂
Damnn I was in kindergarten when this video was made😳
@@Fxxk3 I was 4 years when it's made
ElectroBOOM sent me here.
Better than text book explaination!!!!
I study it in 9 class
@@aryan8684 me too
Obviously
Ikr the textbook part is like an unknown language to meh

Indian students has seen this only in pictures
Yet after paying thousands of rupees in school( business)
So interesting want to see this yr😋😔
How we wish we too were shown these.
yea😕
True😞
Brazilian students too...
Really very true...
Thank you to everyone who helped this video reach 100,000 views.
Sir thanks but this thing shall be done in every school
Sir, This Is very good !!
It is very interesting video and very helpful in lockdown so,
Thankyou so much 🙂and
may God bless you and your family
Sir this is so cool please put more videos like this it's really educational
Sir....... Can u say why that is green in colour...... But not any other colour?????
Such a good teacher! I tried to understand from the book but this explanation was clear and informative!!
😎
Yes
I'm a college student and you can tell this guys is an excellent teacher, you guys are lucky! He explains everything so thoroughly and you can tell he enjoys the subject matter very much.
Omg. You explained this so well, this saved my test grade. Thank you
I wish my science classroom was this interesting
🥺God bless you, I really wish Indian schools impart this kind of education 🌟❤️.
God bless yu a million and more🥺❤️🌟
70 years old, been in electronics for 50 years.
Very enlightening presentation.
Even better yet, I am proud to see anybody that knows electricity is electrons flowing, and they go from negative to positive.
The major publishers and educators pushing for the last 75 years to make a positive to negative current flow, including arrow direction on transistors, at least to me, is a crime against common sense. I will recommend this to anybody new coming along.
YOU ARE A GENTLEMAN AND A SCHOLLAR!
This is one cool teacher
Truly a wonderful and illuminating demonstration.
learned more in the past 2 mins than I did in the past 3 days in class. We need teachers like these.
Respect for this teacher. 👏
Nice experiment, although I wouldn't say the pole of the magnet is negative.
Wow electroboom! Hi
LMAO im doing my semi conductors class, so funny i see you here
Explained the significance and magnitude of the discovery as well as the design of the device so well! Great job!
AWESOME, this is the best illustration of cathode ray tube experiment!! Ive only seen this in drawings. It is amazing!
it really is difficult to imagine how things work and look when images/drawings are only given to you, thank you for this actual demonstration
Very helpful! Awesome teaching! Just one thing: If I'm not mistaken, there isn't a vacuum inside the tube, but there's actually a gas at very low pressure. ( most commonly 0.01 mm of Hg )
Please correct me if I'm wrong anyone; always willing to learn more.
Kryn Rebello From what I have read you are correct. It is a near vacuum, and not a perfect vacuum.
Yes, so that the air molecules do not react with the electrons.
Yes, if it was a true vacuum, it wouldn't work because there would be nothing to carry the current. No atoms means no plasma. In a true vacuum, you can apply all the voltage you want, but nothing will happen.
it would work. we actually dont want any atoms in the tube the voltage is applied from outside and also electrons from a outer source. We just want to see the electron movement in the tube.
kryn u are correct
i wish I had a teacher like this ! inspires a interest in learning when speaking and shows he cares
Why can't yt recommend me this
Probably, the best video to prove science is the best subject ever ! Thanks a lot !!! Honor, Respect !
Finally a video showing the magnet effect. Thanks!
Thank you! I love this video because it presents a clear visual of how the experiment works in real time and you quickly describe the conclusion of Thompson. I was having trouble picturing it for my college lecture so this rocks!
The best part was the deflection of the Cathode rays !! That seems so satisfying !!
Now I Easily understood this concept ..Thank you so much sir ❤️
Easily understood the concept with this video. Excellent explanation sir,
Thank you!
Thanks sir👍
It helped me a lot to understand the Cathode ray experiment. Things are more clear more here than the textbooks.
This video is a contender for "must-see videos for Science people"
Thanks my dude! We need experimentalists like you in science!
people make 30 mins videos on this topic, school makes long presentations that take 45 mins or so,,, but this 2 min video educated me more than any other video or ppt
wow, this was such a clean and clear explanation. Really got me interested the whole time! thank u for posting this video!
Thanks for posting the video. I enjoyed the demonstration and the explanation.
understand the CRT experiment much better by seeing it! Thank you for this video!
Thanks Man!!!! Helped me a lot to understand what actually J.J. Thomson did. Thanks !
I wish if we also had such kind of practical demonstration
It was
helpful and nice. when we see something actually happening in front of us we understand it clearly.
Thank u for video. I didn't get how it work at school and also thanks to your professor for his clear explanation.
This is how education should be.. Loved it sir 😊👍
I'm a bit late, but thank you to everyone who still watches such stuff. We've reached over 1,000,000 views!
BTW, I'm still teaching high school chemistry. I'm currently in Idaho Falls, ID (USA)
Dchummer CHEMISTRY…
😊THANK YOU VERY MUCH 😊
This is exactly what is said in NCERT chemistry textbook of 11th standard. To my surprise, what I imagined about the experiment I read in textbook is same here. Even few sentences that he said matches accurately with the information in the book.
How was ur 12th boards
Wow almost like we observe and then write the results
2024-25 batch here 🙃
3 minutes of this guys video taught me this concept and the profundity of it better than three weeks of college chemistry
thanks for sharing this makes my chemistry research so much easier now
Thompson won the Nobel prize for showing that the electron was a particle. Then his son won one for showing it was a wave. Fortunately, the science wasn't considered settled.
This video was really clarifying, thank you.
Thanks a lot for the cathode ray practical...
I just read about cathode rays on a website but just wasn't able to visualize what they were even though I understood the explanation.Thank you for uploading this video :)
Thanks a lot sir, your video has improved my understanding on this topic. Your way of presentation is awesome!!!
I just studied about this today in class 9,and didn't understood what the experiment would look like THANKS u helped me a lot...
Really interesting!!! Perfectly explained!!!
Damn! This Explanation was so GREAT!!
Mr walker is watching every move I make right this moment
dchummer thanks for the experiment it could be easily understood with this , as the topic is quite difficult to be understood but this is one of the best , once again thank u
Very clear concise explanation
best explanation i have seen so far thnx
Thank you for this effort♥♥
I wish I had teachers like this when I was young!
nice work.....heaps of help....appreciated
Simply great explanation!
Essentially this is the first "video game"
How?
Look it up, this was how they practiced with them
table top tennis was a game from this thing...im sure lsd helped
subatomic PONG, LOL
@j I didn't remember about my comment anymore lol.
I've just checked! Cool! Apperently it was played in an oscilloscope! Neat
What would it be like to have such a great teacher with all these practical methods :)
i studied this at with my chem book.. it's so interesting when you have home teacher to get help with your studies.
DUDE THIS IS AMAZING!!! TEXTBOOKS ARE USELESS THESE VIDEOS MAKE ME UNDERSTAND THIS SOOOO MUCH BETTER THANKS DUDE!!!
What are you doing now buddy
do you still have this account?
This is soo beautiful and indeed you are a great teacher
Amazing teacher !!
U are a really good teacher... Thanks a lot.. I understood much better now
Amazing!!!!
Thank you so much
now this is what I call a real science class
This is a very good experiment. It has interested me a lot. Very nice 👍
Oh! It was nice. The video's clarity is only thing that had this down.
This kind of things need to show on school.
Very much better than teacher's boring lecture👏👏👏
Great video!
Such a great explaination
OMG! That literally was better teaching than my teacher will give me all year! He told us to go on a website to find out what this was all about :(
That was a great explanation. Thank You
Perfect explanation!
Wow it was actually nice
wish this was my science teacher?! (though my 10th grade science teacher was a very good teacher as well) wow so easy to understand and a great visual and an important concept and with some history integrated in too!!
[EDIT: after reading comments, wow you guys are all so knowledgeable!! thanks for teaching me, all of you]
puzz88 where do u live ...if u live somewhere in kolkata then plz give me the teachers no ...i need a good science tutor
thnks for d video............11/11!!!..itz just is simply awesome..!!
I'm fascinated by the Thomson's experiment. Thank you for replicating and documenting it!
I'm wondering what other possible explanations for what Thomson saw could have been (and most likely were) proposed
if only india had teachers like you.
For a visual learner like me, this video's a blessing. Wish my school taught this way :-/
Thank you sir for this practical explanation. This video is super helpful and it's changing lives
Its really fantastic
this chem teacher is very good.
If our schools would have taught this way , we would never get bored!
Indian education system sucks Hume bhi esi padhai chahiye...
MIND BLOWN
Great interpretation 👏
Thankyou so much for the video
Honestly. I wish my teacher taught this way...he is so dull and monotone and we need more teachers like this guy that simply just explains it in an easy matter. lol
thank you so much
Thank you very much
underrated video
After saw this experiment i am fall in love with science
Very interesting to watch
I wish my teachers were as good as you. They just draw the figure on the whiteboard and blabbles throughout the class lol :(
such a great teacher, i couldn't understand the book but i can understand know!
Dude sounds like Nick Cage for some reason :P
Adriana M lmaooooooo
now i can't unhear it
wow! more than amazing!
Thank you 👍💖
