*My reaction after watching this video*
"Science? Chemistry? No sweat mama!"
-Aguam Chem81 EB1
Question! How did Thomson be able to distinquish the particles in his apparatus? how did he have any idea what was going on during the experiment? both in the heating plate and at the end screen.

A remarkable video! It's really good learning new information about the discovery of the electron. Dr. Cox explained it very well that can be understand easily. Great video! worth watching!
A brilliant discovery by Sir J.J Thompson. He opened the gates of the futuristic world.
Salang, Chem81 EB1
Electric current was in fact made of moving electrons.Great discovery Sir Thomson!!
-Paraiso Chem 51 AGC
It is a major discovery in the history of physicis. J.J Thomson was really an amazing person!!
81CSBLara: I watched the other video.. that compiled 1-5.. and downloaded it, for proof.
thanks to J.J Thompson for his great ideas!
loving the hosts vibes right now
Chem1.1A albryancada: Cambridge was and still is a powerhouse in the study of things pertinent to the scientific community to this day. The discovery of the electron (1st sub-atomic particle) by Sir J.J. Thompson with the use of a particle accelerator in the 19th century paved the way for succeeding scientists up to this day in better understanding the purpose and workings of the electron, among other things. Good episode. ✌
this helped me so much for my A-level summer assignment !
it is indeed an honor for us to use the product of the great mind of Sir J.J. Thomson, the ELECTRON.
-CAPAL,M. CHEM 51.1-AGC
1XALLUCH It's amazing how something so tiny actually plays a huge part in our world. Very well-said too!
Sir JJ Thompson contributed so much for us to understand more about what matter is composed of.

1XE YARE: That muffin was delicious, but the lesson about Electrons fed my mind more. :)
Coolsome! :D wish I met Thomson in person, haha!

EXCELLENT !! J.J Thomson discovered the fist subatomic particle - the electron.WOW!amazing!!
Actually, with this experiment, Thompson was able to determine the charge/mass ratio of the electron. Later, Millikan measured the electron charge with his oil dropplets experiment, and therefore the mass of the electron was determined. At least, that's what I learned. Great video anyways :)
1XEANISLAG: *IT IS INTERESTING TO REALIZE THAT MORE THAN A HUNDRED YEARS LATER, the Electron is still the best measurement we can do today. -Professor Frank Close
J.J Thompson discovered the first subatomic particle: THE ELECTRON :)
-OdchigueCHEMEB1
81CSBArrieta: "pretty much all of everything we do in the 21st century depends on understanding the properties of electrons" - Professor John Womersley. Thank J.J. Thomson for his discovery.

WOW! it helps me a lot in CHEM!
1XEBACANTO: Truly, the electrons are important because it is the only fundamental particle that takes active part in any chemical reaction.
IXARAFISURA: ahh, Thompson discovered the electrons is not the fundamental building block of matter, there is smaller objects inside. hmm. :D
1XAJUMAMOY- The Electron was the first fundamental particle to be discovered? The world DOES have a negativity bias...
ELECTRON is a subatomic particle with a negative elementary electric charge. MorenoChemEB1
Discovered the electron? Woah. Sir Thomson was really a MAD GENIUS! Unbelievable!
DuctoChem81EB1
It's so fascinating how the electrons paved the way for numerous scientific discoveries :)) -WalagCHEMEB1
How in this world they have minds thinking of those complicated things. Simply CAPTIVATING. :D
-Lindongan Chem 51 AGC
1XEEMANO: The video shows that Electrons are important, without it, atoms will not be formed. That's what I comprehended after watching it! And oh great I love it. Haha
81CSBLABASTIDA: thanks to Sir Joseph Thompson.. he is a brilliant scientist...
Great minds discover great things. It's amazing how people explore and discover things that are very useful. - CortezChemEB1
81CsBManzanades: without Sir Joseph Thompson, electrons won't be discovered..
Lisod sabton ang accent ni JJ Thomson. "Shakespeare" lang akong nasabtan. may nalang dili cya atong teacher
- GallaresCHEM81, EB1
J.J Thompson was a great inventor and a brilliant scientist.

1XENATAN now i know that J.J Thomson discovered the electron designed to study the nature of electric discharge in a high-vacuum cathode-ray tube
Indeed sir JJ Thomson is a very brilliant man. Great discovery, sir! -GABUTANCHEM81EB1
I'm dazzled with Sir Thomson and his discovery.
Padilla Chem 81, EB1
ok can anyone answer this question for me, since I am not a typical science know it al. How can they just shoot electrons only thru any experiment, when I thought electrons are part of the atom, and atoms can not be torn apart into seperate particles? Do we have the technology now to suck away just the electrons from the atom and shoot them thru a beam like this experiment is suggesting.
thanks to JJ Thompson electron was discovered DalapagChemEB1
This shows how electrons are generated to have an electricity.
-81CSBGalvadores
81CsbCabillan: J.J Thompson IDOL ! Discovered the Electrons
Sir J.J. Thompson is so smart to discover the first subatomic particle which is the electron. _Cahucom52agb
1XAGUYLAN: It is interesting how Thomson discovered the electron which contributed to the world development until now.
Electrons orbit the atom, and can be shot out of orbit by something as simple as light (photons, the photoelectric effect). We have technology incredible enough to create anti matter in laboratories, controlling the flow of electrons isn't very hard.
the lightest known particle in Thomson day was hydrogen atom but Thomson found out that electron are almost 2 thousand times lighter that than hydrogen atom
-LI CHEM EB1
1XASUSON: it tells about the discovery of the electron, the smaller object inside the atom.
81CSBMaligmat: thomson`s discovery contribute a lot in today`s world
81CSBBragat: Brilliant Discovery Sir Joseph Thompson
1XABERADOR: Electron is inside the atom? interesting, because we all knew that atom is just a small particle.
Historically-bounded, scientific jargon, electron discovery - Thomson be credited. How fantastic it could be if I could go into the featured Cavendish laboratory. (For classroom purpose: This is Nikko Galarrita - XE)
the answer is "Yes" You need to ask the right questions. 1st Find out what electricity is made of and its uses. Microwaves can carry frequences... I know I missed spelled the word, but that the least important on the subject
1XADANAOTO - Smaller objects inside the atom? Well, that's interesting!
81CSB Laviña : every positive there's always negative behind it ? right ? :D
A salute to Sir Thompson.
-PangcatanCHEM81EB1
this video really helped me understand more about the electron :)

That was Very informative video- Panuncial52AGB
This video is about electrons. #FiveWords #Electrons
-Dalde Chem AGC
hey wait, Thomson did not know the mass of the electron, he knew the mass - charge ratio. It was millikan's oil drop experiment which discovered the mass of the electron
i have watched this own video of jj thomson first on this site,,,thanks a lot youtube,,,hope to get these types of videos,,,like of e.goldstein,rutherford,,neils bohr
idk i would think if it has waves you could find a freqency and control it by certain rythme or flow of electricity current , but im only 14 lol , sounds interesting
81CSBPingkian: This video is very helpful and interesting ..
So wow much awesome and interesting

What a genius! Sir JJ Thompson is really awesome! - RayponChemEB1
Electron is already part of our lives. It also contributed a lot to discoveries. It is very amazing that it is a long long time ago but today it is still useful to us. Emano_81CSB
1XADEPEDRO: I didn't know that there was even something smaller than an atom. So this was a new lesson for me.
Particle accelerators are potentially dangerous. -Borja CHem 51 AGC
so cool.!! nice one J.J. Thomson for discovering the first sub atomic
particle called electron.!! yeah.!

1XASANJUAN: For a minute I thought the atom was the smallest particle, here comes the electron.
wow!! we sometimes dont care about these electrons but they play a big role in science. -Leysa CHEM EB1
1XAPANTANOSAS The electron is indeed small but great!
I want to see how JJ Thompson's accelerator works. - CabanazChemEB1
wow. nice. speechless. five. words.

1XAABANES: through electron we can makes some machines.
81CSBNocete: Never thought Negativity is an important part of life.
1XALIBRANDO: A good way to start learning electron.
full of knowledge and learnings
Gamotin(Chem81 EB1)
Of course, the greatest of endeavours strat from the smallest and "unimposing" of things... Once again, start at the basics...
Tesla discovered electron way before thomson that disagreeed ironically at first
81CSBPagtulon-an: A great discovery of a great man.
81CSBPelayo: It can prove materials and structures.
What the hell is up with this "81CSB" nonsense in the comments?
+Kabitu1 spam probably
+Kabitu1 it's an assignment in our university, we should leave comments in this videos with our class section in it. it may seem a spam but it is only a way for our professor to identify us
