How Rutherford Split the Atom for the First Time

- Ernest Rutherford was one of the greatest scientists of the 20th century, and was arguable the biggest pioneer of nuclear physics. This video covers his last major discovery: That alpha particles, when bombarding nitrogen atoms, cause the nitrogen to transform and release a proton in the process. This was the first documentation of a proton being expelled from the nucleus of an atom.
Rutherford doing the exacting and thorough work that only the best scientists do.
Excellent video, well made and superbly researched
Another great video. Thank you, and keep up the good work.
Interesting that Rutherford could do a lot of the same things, if you think about it, with a just a speck of radioactive material, that in more recent times one might think to use something like a cyclotron of a bevatron. Boggle. Liked the 'gold foil experiment.' Using bits and pieces from a sewing kit and an electronics scrap box, you should be able to construct a low power (perhaps a few hundred million electron volts scaled) accelerator producing energetic positively charged ions to fool with that might pass through an aluminum foil for a centimeter or two? By implication. If you have a Geiger Counter of some sort, to keep track of the interactions, you might be able to do some interesting experiments. I did not know about Rutherford's second Nobel, good for him! A giant of relatively recent times. Reminds me of Curie. Many thanks for the clip, profound.
Nitrogen?!? I was expecting uranium or some other heavy element...
Thank you for this lovely account of history that deserves to be remembered: A time of giants
Another great video! Keep it up!
He was a Kiwi.
No. He was a mammal. A kiwi is a kind of fruit. Although his head shape does remind one of a kiwi. An easy mistake.
@funwithpliers Actually, a Kiwi is a type of flightless bird. Slang name for a New Zealander. And another name for the Chinese gooseberry.
I had scientific 1918 magazine which did include article of Rutherford experiment.
"Spitting of the atom" does not refer to the process described, although it is indeed induced partial splitting and a major achievement.
Furthermore, Rutherford went on to develop atom smashers but the spitting the atom and releasing more energy that was put in , remained elusive, leading him to claim that nuclear energy would not be possible for another generation.
Fermi was the first to split the atom. Otto Hahn, trained by Rutherford in nuclear chemistry repeated the experiment and found boron. Lise Meitner was then able to deduce that U235 was split but Hahn took the credit as Meitner had escaped nazi Germany.
The problem with recognizing Rutherford as being the first to split the atom is that his experiment did not lead to energy production, reactors that produce plutonium (the major fissionable material) or bombs that we associate with nuclear fission, whereas Fermi's did. This point is historically important as Fermi defected from Fascist Italy to the USA, had he not done so the world might have been different.
DUDE HE SAID PRIVATE
Dang, you got me...
Whichever the way he did it, he made me fail in physics!!!😂😊😂😊😂
E.T.S Walton split the atom for the first time.
Thank you for that fascinating history lesson 🙏. That really was an excellent video 👏🤩
what's the big deal about splitting the atom? anyone can do it, just get your atom, put it on a solid surface, get out your chisel, carefully put it on the atom, then wack it with a Mallet as hard as you can, and the atom will split in two, easy peasy! Just be careful cos the pieces sometimes fly everywhere and it can be a devil to find all of them🤣🤣
Incredibly smart men.
Sad that most school only teach that he came up with a later incorrect model of the atom, and nothing more.
And i thought that Professor Proton has discovered it ...
More inspiration for this PhD student. Great video 😁
Thank you, good luck on your PhD!!
He used a katana.
Well done!!
If only people ad Einstein, Rutherford, Bohr and Schrödinger could come back and get a tour of CERN
Cern is a money eating machine. Nothing is going to be found because particle theory is a HOAX.
@ 5:33 This photo gives a "nice" picture of the role women could play in science. Do we see Marie Curie here?
I don't think that is Marie Curie.
Curie appears at 5:45 behind and to the right of JJ Thompson.
She's a student. That is at Manchester University in 1911. She is also in the 1912 photo, along with another woman. And again, alone, in 1913. Who she might be is a great question...
Found her.... the original of the 1910 picture has the names of each. There it says "Miss M. White".
Apparently she is Margaret White Fishenden (1889-1977) BSc; MSc; DSc; FInstP
She has a wikipedia page too. She had a long career specialized in heat transport.
@@TheAlchaemist Thank you. I'm going to read her Wikipedia-page to find out what made her such a special woman.
math is solid it is just amassing how computers make mistake META AI has it Ol wrong to anybody have the same problem?
At min 1:16, what is the component M? Is a source of high energy used in the experiment or is just natural emissions from the material on the slider component? I think the video needs some extra info.
M is the microscope
Splitting an atom is a very slow process, useless for war-wespons..perfect for nuclear power🍏
McGill!!!
you a math guy it is a lonely job nobody can other stand this this is way he gets frustrated
It is amazing how those great people of physics had broken the atom into neutron, proton, electron and positron! All that was a very slow process, but they were exactly right with these particles. Then some idiots appeared and had led the particle physics completely astray. Idiots still believe positron as antimatter which make half of all the meterial universe. I don't even like to pronounce the stupid word "quarks." Thank you very much for this vedeo.
You should read up on radioactive transformations like beta emission and you will see why quarks are needed.
@@karhukivi Do you mean, needed in a mathematical sense?
@@jacobvandijk6525 To explain how a neutron can change into a proton with the emission of a beta particle and an anti-neutrino, or a how a proton changes into a neutron with the emission of a positron and a neutrino. These types of decay can be seen in a cloud chamber, hence the need for quarks to explain how these transitions occur.
@@karhukivi oh, interesting, some thing more you have to explain. How do quarks holding an electron? Why it is relieving the electron after a while when the neutron is free? What is the roll of quarks in the beta decay process? Had Murray gellman and George sweig told about any thing beta decay when he proposed the idea of quarks?
@@surendranmk5306 I'm afraid I can't answer those questions! The way science works is that to account for experimental evidence, a theory has to be postulated and if somebody comes up with evidence that disproves it, then the theory has to be altered. The theory of quarks accounts for most of the experimental observations, but who knows, there might be some other explanation waiting to be discovered.
A proton is a collection of 1836 expanding electrons and add a bouncing expanding electron makes a hydrogen atom. “G” calculated from first principles- the hydrogen atom- in 2002. “The Final Theory: Rethinking Our Scientific Legacy “, Mark McCutcheon for proper physics including the CAUSE of gravity, electricity, magnetism, light and well.... everything.
LOL, no.
@@borisjohnson1944 And the cause of gravity is? Laugh.
@@davidrandell2224 LOL. So some numpty on the internet has the answer? Got you sucked in.
