    Probably the best explanation of basic chemistry and it was given 60-odd years ago. Returning to organic chemistry, it was refreshing to review the basics taught by a master.

      Extraordinary. I just loved how while filling up the 3p atomic shell with electrons and naming the corresponding elements he mistakenly mentions scandium in place of aluminium but then when he went on to fill the 4th shell where scandium actually should appear he suddenly remembers the mistake and went back and admitted he should have said aluminium. Such an actively beautiful mind. One cannot but be in awe of someone with this level of intellect.

      As a philosophy Ph.D. with a BS in physics, I agree. I am reading Pauling's book "General Chemistry" and am blown away by the clarity and depth of understanding that he conveys. There is NOTHING LIKE learning from a true genius and pioneer of the field, a principle that probably applies across many if not all disciplines. (This is why Bertrand Russell, a brilliant philosopher AND mathematician/logician, told students new to philosophy that they would get more out of reading passages from the historic "greats" (Plato, Kant, etc.) than they would from introductory philosophy texts - an approach I tried to follow when I was teaching. Of course Russell's own texts are excepted, since he IS one of the historic greats...)

    The L. Pauling's resonance theory analyzed using principle of quantum
    superposition, that is the principle of superposition "wave function", which is the main positive
    principle of quantum mechanics. The principle of quantum superposition is essentially a basic
    property of the wave function. By example of benzene molecule is shown that the principle of
    quantum superposition, and hence the quantum mechanics in general is in insurmountable conflict
    with the resonance theory.
    Quantum-mechanical aspects of the L. Pauling's resonance theory:

    @aligborat oh and while we're at it...where the heck did I say quarks were discovered in 1987?...and you're point is invalid anyways, because if you'd taken a second to read the description of the video...they were produced in the 1950's !!!!...almost 18 years before quarks or partons were discovered. Dr. Pauling is talking about them...sure they later discovered that it's only neutrons and protons, not electrons. But this is before that size of matter was even considered possible.

    You said Columbia U "reversed" their findings, it didn't take anyone 10 years to refute cold fusion, it took a few months. The first quarks were discovered in 1968 which would be let's see would be 11 years after this film was made, not " 30 years before the first quark was observed" Noticed that, I quoted that one exactly.

    Linus Pauling was unbelievable. He held 48 PhDs! He received two uncontested noble prizes. If you listen at around 1:50, he's talking about quarks. This video is 7 years before quarks were proposed and about 30 years before the first quark was observed. My MSE teacher got to meet him at a conference once. He said a person asked him about the "cold fusion" work being done at Columbia U and Dr. Pauling immediately explained the errors. 10 years later, Columbia U reversed their findings.

  • @aligborat

    Dude, you need to fact check before you post, first off the "cold fusion work" was done at the University of Utah, not Columbia U, and it was proposed and refuted by scientists within about a 6 month period back in 1989, not over 10 yrs. He isn't proposing quarks in the lecture because he mentions electrons being made of smaller particles and they are not, like quarks they have no substructure. It was just speculation on his part, and lastly the first 3 quarks were discovered in 1968, not 1987.

  • @aligborat
    @aligborat 13 лет назад

    How did I pull 1987 out of my butt? You said they weren't discovered until 30 yrs. after this film which was in 1957. They were observed in 1968, it's just that no one knew what they were at the time. They were belatedly recognized as such later, but the evidence was there. I'm not trolling, just correcting the historical record, because of the comment about cold fusion, which I see what you were trying to say, but the comment wasn't exactly clear and that 10 year comment made the meaning muddy.

    The reason of the formation of the chemical bond.
    The reason for the formation of the chemical bond is still not clear, in fact, there is no physical justification, as it was at the time of Bohr, since the formation of a chemical bond does not follow from the four fundamental interactions. Just imagine, a chemical bond "does not understand" that it can not be explained normally and quietly exists :). A full explanation of the chemical bond can only be provided by quantum mechanics (in the future), classical approaches simply do not work.
    To understand this, it is necessary not to forget what L. Pauling did (L. Pauling, "The nature of the chemical bond", and the work of L. Pauling: Chem. Rev. 5, 173 (1928)), namely Pauling analyzed the interaction of the hydrogen atom and the proton in the entire range of lengths (he admitted that the hydrogen atom and H + on the approach are preserved and showed that the bond is not formed in this case (since there is no exchange interaction or resonance by Pauling)).
    Only one of the above-mentioned facts actually destroys the classical approach (attraction and repulsion by Coulomb) to explaining the chemical bond. There inevitably follows that the chemical bond is a quantum-mechanical effect and no other.
    Imagine a system with two protons and one electron, but if it is treated as a hydrogen atom and a proton, then the bond can not form over the whole range of lengths. But, as Burrau showed, the bond in H2 + is formed (if we consider the system as two protons and one electron), and no one particularly doubts this, since H2 + exists. I particularly emphasize that there is only one electron (there is no inter-electronic repulsion, etc.).
    After this fact, further discussions can not be continued, they do not make sense (especially to apply this to the explanation of two-electron bond or aromatic, this is a slightly different level of complexity). But nevertheless, it should be noted that quantum mechanics introduced the concept of "exchange interaction", which had no physical justification (since no fundamental interactions are altered in the interchange of electrons, but should, if a bond is formed) explained the chemical bond (more accurately, "disguised" chemical bond into the quantum-mechanical effect of the "exchange interaction"), by this, confirming that the chemical bond is indeed a quantum-mechanical effect.
    The science of chemical bonding is only at the beginning of it's journey, and it is for today's students to make the most significant contribution to the theory of chemical bonding. And this will lead to fundamental changes in understanding both chemistry and physics.
    On the basis of modern concepts of quantum mechanics, chemical bonding can not be explained, fundamental assumptions are needed in quantum mechanics itself ...

    @cuthwulf Now quit "trolling". We all see that you want to be smart badly. You're missing the whole point and you have found yourself arguing that Pauling was not amazing...this alone proves that you haven't opened a science textbook in your life but rather thought it would be fun to google some answers and try and sound like you know something. Pauling's work literally is found in almost every branch of science. Arguing that he is not amazing only proves how little you know.

  • @aligborat
    @aligborat 13 лет назад +1

    I never said he wasn't a great scientist, just that he didn't predict quarks. Lord Kelvin didn't invent aerodynamics but it doesn't mean I don't think he was a great scientist. You sound like one of those fanatics who has to believe their heroes had a hand in everything important developed during their lives. Pauling was still great, just like Mendeleev was great, although Mendeleev didn't invent atomic physics anymore than Pauling invented quarks. Sorry I touched a raw nerve, buddy.
