  • 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.

    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.

    "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.

    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🤣🤣

    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.

      @@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.
