It was the universe's most elusive particle, the linchpin for everything scientists dreamed up to explain how stuff works. It had to be found. But projects as big as CERN's Large Hadron Collider don't happen without dealing and conniving, incredible risks and occasional skullduggery.
Buy Sean's book "The Particle at the End of the Universe" - geni.us/LQYMuM
Award-winning physicist and science popularizer Sean Carroll reveals the history-making forces of insight, rivalry, and wonder that fuelled the Higgs search and how its discovery opens a door into the mind-boggling domain of dark matter and other phenomena we never predicted.

  • Just came to say this to Sean Carroll - Sir! I can't thank you enough for sharing and explaining the kind of complex stuff, for ordinary people like me. Your lectures make the world better. Thanks a million. Keep up the great work!

This is important for many reasons. The more parents that are interested in this, the more children will be inclined to work in the field when they grow up, meaning society at an even greater pace will wander towards new scientific breakthroughs in the future. And this will also influence politicians to fund research. Combined with the necessary evil that is greed, new companies will pop up and drive us to the stars. I know this escalated quickly, but channels like this are so important.

  • Jeff B: First, under special relativity velocities are not additive, there is a correction term, velocities don't just add up simply. If v1 = v2 = 99.999999% of c and we plug into the velocity addition formula ( v1 + v2 ) / ( 1 + ( v1 * v2 / c^2 ) ) since we're working with fractions of c it simplifies to to 2*0.99999999 / (1 + 0.99999999^2) = 0.9999999999999995 (a hair less actually, copypaste into wolfram alpha if you really care about all those digits) To each particle the other particle looks like it's travelling towards it at that speed, and from the reference frame of the accelerator both are doing 0.99999999 * c in opposite directions. The rest mass of a proton is 0.938GeV/c^2 (this is the e=mc2 formula) and the total energy of the proton (mass plus kinetic energy) is ~2.1TeV ( (0.938GeV/c^2) / sqrt(1 - 0.9999999^2) - this is same mass energy equivalence formula but with a nonzero velocity term). When the protons collide their quarks will interact and transform to a range of new particles. these interactions are studied in great detail by looking at what sort of particles fly out, what velocities they have, how they move in an electromagnetic field, etc, that's what it's all about in the end, learning about the statistical properties of the fundamental interactions of elementary particles. Because you have 4000 as much energy as there is in a proton at rest you can produce much heavier particles (mass energy equivalence goes both ways) than the protons you started with (as long as they end up moving more slowly), and generally see them decay and produce a whole range of particles (elementary and composite). Note that wikipedia says 4TeV per proton so those nines are probably rounded =)

(Boson). Another example of western appropriation of Science and philosophy. Democritus, Plato and Aristotle's and all Greek philosophers' great guru, Ptolemy, is believed to have travelled through India for 10 years before transferring the knowledge of atoms and philosophical reasoning to the west.

    • ***** it has to be a dual "reality" -- unobserved it's all fields, observed it's particles. wave/particle duality, same thing, it's both. Duality is intriguing. In black hole physics there is a dual description of reality where Bob can fall in and hit the singularity in an hour, but Alice sees Bob falling slower and slower and taking an infinite time to reach the event horizon, never reaching the singularity at all. In ADS/CFT duality, quantum field theory in flat space at high energy is dual to string theory in Anti-deSitter Space at low energy in 1 higher dimension. (In this usage, "dual to" means "has the same math as.")

    • N Marbletoe A recently discovered duality may solve Einstein's dream of unifying Relativity and Quantum physics: quantum entanglement is dual to non-traversable wormholes (EPR = ER). Since entanglement is everywhere (empty space is near maximally entangled with itself), spacetime is apparently full of wormholes (Einstein-Rosen Bridges). This is a very new discovery and begins to give a geometrical description of quantum mechanics.

  • Really like this video, but I don't like the general statement "there are no particles, only fields". particles are excitations inside the fields, and perhaps it is true they are all massless by nature until running into the Higgs, but "particle" doesn't mean "has mass", and therefore it's wrong to dismiss particles. After all, Bosons are considered "particles" in the Standard Model, and they are massless. This becomes important when discussing the slits experiment, and Quantum Mechanics interpretations (Copenhagen, de Broglie-Bohm, or "many worlds"), as the core argument between interpretations is of the existence of particles (vs just fields and/or waves). No one has yet "won" the interpretation game, so should we simplify already by saying all particles are really just fields and waves producting results within our senses? Great video to spur the mind, but obviously lacking rigor and preciseness in order to shed some simpler light on the Higgs and the Standard Model. they key phrase one has to be aware: "As long as Quantum Field Theory is right, we know...". Indeed, we don't know if QFT is right yet. Stay tuned, there are very exciting developments in experimental physics which are shedding light on just that very question-- see Aephraim Steinberg, and fluid-dynamics teams in Paris and MIT for details.

    • "Really like this video, but I don't like the general statement "there are no particles, only fields"....the Higgs and the Standard Model." I think the appropriate response stems from your next section: Carroll is discussing things in terms of Quantum Field Theory (QFT) as opposed to Quantum Mechanics (QM). QFT does not define particles, so it is perfectly accurate to say: 'In QFT "there are no particles, only fields".', though it is a bit silly since it is tautological. QFT does discuss sustained field states that correlate to particles in QM. But in QFT, the term "particle" simply has no meaning, and that is what he is trying to convey. The things known as 'particles' in theories that have particles are still represented. It is just that the representations are not inherently differentiated from other field phenomena, but instead an internally artificial and externally relational designation is necessary to translate back and forth. "they key phrase one has to be aware: "As long as Quantum Field Theory is right, we know...". Indeed, we don't know if QFT is right yet..." QFT is right to a point, as it successfully describes some things better (by some definition of 'better') than other theories. Just like Linear Expansion is right to a point. In terms of QFT, we just don't know precisely where that point is yet. And that is where the excitement lies.

    • It's becoming borderline irresponsible to believe in QFT at this point, as both experimental proof AND theoretically-better theories are making much more sense. If you really take QFT to its limit, it forces a physicist into believing there's no causality and therefore no free choice, so what's the point of life? We're all on autopilot anyway. That just doesn't make any sense, if you start by believing anything, there's nothing to believe. It's circuitous meaningless contradictory drivel. Whereas in Bohm interpretation, it's a start in the right direction, and those pushing even further like Louis Vervoort (for example) are now pushing even Bohm interpreation to the back shelf in favor of more exact and meaningful non-local field theories, or as Vervoort labels it.... "opens the door for local ‘background-based’ theories, describing the interaction of particles and analyzers with a background field, to complete quantum mechanics." Vervoort is likely going in the proper direction here, makes tons of sense, especially when you consider the small sizes of things discussed in string theories. We might be right back to the "aether", albeit not at the size the 1800s Physicists were expecting (they looked at the atomic level). When you combine background-based theories with the fact of estimated sizes for Planck length, it's easy to see that we might be able to account for the aether but without actually ever getting to experimentally SEE it. String theory might be wrong, but the math is probably going in the right directions there to allow someone eventually to push thru some math explaining Bell's Inequality problems within Bohm Interpretation. At long last we might actually "double-jump" to the correct and final interpretation of Quantum Mechanics, discarding the last 100 years of mystical believe that the world is nothing but a mass-less vacuum-ensconced probability equation (field) that only takes shape when you look at it. think about this, it's ridiculous, and now that we have some evidence and theory that makes total sense, there's just no more reason to believe in Briane Greene's and Niels Bohr's wave-equation QFT "boogeyman" anymore. Check this out: link.springer.com/article/10.1007%2Fs10701-015-9973-7 Maybe read some of Hiley's papers first, just to understand the Bohm interpretation before getting into 2nd derivatives of the theory like this, but good nonetheless.

      @TenHanger@TenHanger7 жыл бұрын
    • TenHanger​ I think you may be failing to differentiate between what theories actually say, and what people say about theories. QFT does not assume causality, nor really discuss things in those terms. You can't really discuss the meaning of the word 'chair' in a dialect/language that doesn't even have that sounds sequence as an existing word. Likewise, QFT. That doesn't make it right or wrong, just a particular way of talking about things.

    • Why is there space? This is a null argument as space is absolute nothingness, These scientists are wrong to assume that fields occupy all space (nothing abyss void) they occupy only the sphere which is the largest 'particle of all - the universe/cosmos. Outside of that sphere is the void absolute which contains abs nothingness which contains nothing; neither particles nor fields. As space is a nothingness or essential ground, it is not a thing therefore it cannot 'exist' - it just 'is' in the negative.

    • Zayan Watchel The issue goes a little deeper than that. Sean Carroll chose to incorporate that bit for a reason. Considering that women that have made significant strides in hard science but haven’t gotten any recognition until very recently, the statement was necessary as women tend to get brushed under the rug in the scientific community because of institutional sexism (i know, scary word) . This is why many women had to submit their writings under a males name or a anonymously- otherwise, they’d likely be immediately discarded. To reduce this to political correctness shows your own ignorance, honestly. Consider doing your own research and educating yourself, if you all are such intellectual science enthusiasts, rather than making edgy comments because someone who actually cares about hard science making a statement about something he feels is important and relevant to his talk triggers you.

In fact the very idea of feminism, and women's rights are praised in our society not degraded as they would be in an institutionally sexist society. If they don't get recognition first of all the question is why? Very few scientists become famous, or get recognition and there are few women that CHOSE to go into stem. As such could it just be none have really gotten much recognition. not because of sexism but because they never did anything worth recognizing for any length of time. "Until very recently" and now they have been recognized when they do do something great.
