- Symmetry is when things are the same around an axis. Turn it and it looks the same. A simple idea with profound implications for understanding the universe and for predicting how it works. Finding symmetries, and discerning when they break, is one key for understanding fundamental physics.

Looking for symmetries is a way of glimpsing into the workings of the physical world and it’s beautifully organized manifestations. It’s also a form of systematic book keeping and objective cataloging that go hand-in-hand with our physical and mathematical investigations. Without symmetries and symmetry breaking it is almost impossible to study concepts like Conservation Laws / Principles , Invariance, and even certain philosophical notions such as Objectivity.
Eloquent and timely explanation of symmetry by Robert Laughlin. Timely because I've been wondering about the symmetries expressed in the Feynman diagrams, and how they might relate to fundamental cognitive (semiotic) processes, especially in the context of association. There's that one famous diagram that especially stands out for me (cover of Kenneth Ford's World of Elementary Particles, 1963), where a proton enters from the bottom, and it divides into numerous other particles along the vertical (time) axis to finally recombine, at the top, as the (same?) proton. If that's not symmetry, then I don't know what is.
@@cosminvisan520 In previous posts to CTT, I mention:
1) Charles Sanders Peirce within the context of motivation, association and habituation as fundamental principles (firstness, secondness, thirdness), and that this Peircean interpretation is relevant to every kind of mind-body (holon), including cells and neurons (Eric Kandel);
2) The implications of cubed root reduction (with reference to Geoffrey West's book Scale), and the idea that as particles approach subatomic sizes, they lose their Newtonian properties, in favor of top-down directives coming from the contexts in which they find themselves - this might go some way to explaining complex interactions at the cellular/neuronal/synaptic levels;
3) The Feynman diagrams remind me of the *triadic scheme* (semiotics) that connects Representamen with Object with Interpretant. There's something about the Feynman diagrams that invites semiotics and association to play some kind of fundamental role.
As we approach subatomic sizes, I conjecture, the usual mind-body (holon) relationships dissolve and are replaced by "raw" semiotic processes as they relate to the known versus the unknown, hence the relevance of virtual particles and the creative void - the void as a hubbub of associations playing out, submitting to the symmetries that yield matter.
This is the conjecture I've been toying with. Obviously, I cannot prove it, as I am not a physicist. But I think it helpful to brainstorm this approach further, because our physical/life sciences appear to have hit a brick wall. Check out Brian Keeting's recent interview - Neil Turok: My Advice to Physicists (October 16) - that illustrates nicely what we are up against. We definitely need to find a way out of this mess, and Turok is echoing the same sorts of concerns and disappointments. Time to look for something simple, outside-the-box, and which hangs together within an axiomatic framework of consistent principles. And bringing semiotics into the narrative resonates with Robert Kuhn's recent exploration of consciousness as cause.
Lmao you clear don’t understand symmetry
Ain't that simply a way of drawing the proton in terms of its quark components?
4:15 - It should not be forgotten that the Universe has no _obligation_ to follow simple or elegant laws. It usually does, but "guidance by elegance" can lead us astray.
6:50 - OTOH, when you calculate the properties of a system from "first principles" (whatever they might be) and your prediction matches experiment/observation, this gives credence to your understanding of those first principles.
Brethren Brethren Brethren! Let us not divide ourselves with scripture, but unite ourselves in spirit that among us some or one will finish the race. And I have absolute faith our race is finished. I'm going to get another beer.
I love this guy, its just now and then one of the guests is on another level and this guy is one of them. Sean Carroll is another.
@@cosminvisan520 your explanation for things then would be…..
@@cosminvisan520 well that’s one possibility, but it’s only that. It’s not a fact of reality and a proven explanation
@@cosminvisan520 no it hasn’t been. Prove it.

what is organizing in symmetry? when there is time symmetry for conservation of energy, how does time organize as symmetry?
Can this hypothesis has possible meaning: Time can be explained relative to energy i.e., imagine at relativistic speed a region is created
of the energy (potential) due to that
less energy is transmitted for the observer outside the region. This indirectly explains that time can be rate at which observer observe the energy?????
Symmetry is a balance and nature strives to always balance things out.......doesn't always succeed but it keeps trying.
Could it be that nature expresses a preference for symmetry simply because it is more effecient than the alternative?
A sphere both extends outward at all points and returns (curves inward) at all points at all times. I am trying to get symmetric with that. I can't go home to Venus until things cool off a little. So much pressure.
Lack of symmetry leads us to discover what kind of conservation is required. Symmetry leads us to conservation of everything.
What if you find symmetry somewhere strange?
Like, I realized, if you write the alphabet around a circle the 5 vowels and the three letters shaped like the number 3 are symmetrically placed.
I’ve checked other alphabets and I’ve not found this property anywhere else. It seems odd that an alphabet that took thousands of years to evolve would have symmetry within its order
I’ve done a video explaining it on my page and have made tons of diagrams and art pieces #ABCMandala
what letters look like 3.. except E
@@DroppinJewels31 M & W.
Also E(5) is the 3rd Prime number, M(13) the 6th, and W(23) the 9th…so just as M &W are the same shape rotated so is 6 & 9
If you represent the number 2 as the universe then 2 = 1 + 1 or 2 is equal to iterations of 2 such as 0.5 + 0.5 + 0.5 + 0.5 = 2 and it cannot be otherwise 2 must be equal to the sum of its iterations!! Symmetry is pure logical consequence of entailment, the left side of an equation must be equal to the right side of the equation, that is symmetry!! So, all of mathematics is built on symmetry and its conservation, all of mathematics has an overarching rule which is the essence of mathematics and that is symmetry, all of mathematics has to conserve symmetry!! Logic is pure symmetry, logical validity is a conservation of symmetry!! Everything can be described mathematically and everything is symmetrical, everything is ruled by symmetry and its conservation!! Even the creation from nothing is a conservation of symmetry, if the total energy of the universe adds up to nothing then that is a conservation of symmetry, the nothing prior to the something that appeared is equal to the something!! Something then becomes just an iteration of nothing at all!! Symmetry is the most overarching fundamental principle in nature!! If experiment finds that the total energy of the universe adds up to non-zero then you need to zoom out in perspective and find a larger whole where the symmetry is conserved?? Maybe we have a twin-mirror universe which when added to ours adds up exactly to zero??
You wouldn't say 0 (nothing) is equal to 0 plus something, would you? The universe is not 'nothing'.
@@samuelarthur887 maybe the universe is not "nothing" but God is acknowledged as 'nothing' in the sense of negation, netti netti -- not this, not that. God is not a thing we precieve here in the phenomenal plane.
However, the ancients did arithmetics, 0 wasn't a thing, One was the principle. They preferred arimetics over mathematics so I've learned.
The water droplet has an outside layer that is polar and produces a sphere in space.
The universe is at the center point inside a 11 sided mirrored box! All the information comes from the same point. It just depends at what angle your observing. It's more likely we are actually a holographic ball. All information is entangled and has super symmetry. I like to think about an old movie projector and the image appears on the wall. Our reality is wall and quantum physics is the light in-between the wall and the projector. The actual projector is the program and who ever hits the power button is god.
'Symmetry is not a cause but a consequence' ....that applies not only to physics but life as well .
symmetries are the product of competing but harmonious pressures
But the "Geist" (self, spirit, subject of knowledge, the real living entity etc.) only comes to itself to the same extent that it recognizes what in principle eludes all theory and empiricism!
To Be, and know it. This is what consciousness is. The entire head scratching puzzle reconciled with the divine in just five words.
Now let us pray 🙏 for more discernment. Thanks u
Oh you want to reverse, the obfuscated wiith physics, sciences and Einstein...it couldnt get anymore gay than that and that continental divide in the hegelian empire
Symmetry I think of Unity, balance, wholeness; Oneness, energy, light, life, vibration. Look at sand tables, vibrations, geometry,. I consider too the eco system as a type of symmetry. Is God reflected in all things, as all things are in God. The lack of symmetry I say is because of matter, time, decay. Matter doesn't cause symmetry. There's an energy, light, vibration( all One) which has this Oneness and beauty, unity, harmony, which we title God. Symmetry is like a glimpse of God, because of the unity, Oneness, balance, perfection; tho only temporary here.
Some here think laws of physics produce symmetry. No. The laws are also part of a symmetrical system. Roundness is a quality, a thing may recieve this quality but does not become this intelligible quality. This quality is also beyond physics(nature).
There are ideologies that are aligned with nature and cause symmetry. And then ones that are crooked and misaligned with what nature wants.
All negative states are positive states which haven’t fused. We understand symmetry by unifying with our own collapsed representations and the way they express.
i didnt get it
Nature goes for symmetry and not for symmetry, goes for simultaneity and not for simultaneity - and so on.
A frequent question.
If modern physics is so wrong, why does it work?
Firstly, to answer this question is that if you are a modern physicist, I am certained that you actually “do not” understand modern physics. Please do not tell me that you had work on modern physics the “rest” of your life since you may “not” know where modern physics developed from. Because modern physics was developed from Einstein’s 4-d spacetime continuum, which is “not” a physically realizable paradigm. Secondly why does some of that modern physics work? The answer is that; those modern physics work does not violate the law of nature [e.g., 2nd law of thermodynamics, law of temporal (t > 0), law of conservation energy, law of entropy]. From which we see that it is those principles and theories that contradicted the physical realizability (i.e., boundary) conditions of our universe. For examples, Einstein’s relativity theories, Schrödinger's super position principles, Dirac’s anti-matter, Feynman’s QED, Hawking’s Black hole, Wormhole time-traveling and others.

We don't. The most beautiful women are not perfectly symmetrical. In fact the face is more rich when every side radiates a different vibe, one side more happy and youthful the other more broken and serious. The combination communicates much more about the person. Just test for yourself and obscure one side or the other. The mixture is always better 💟
An ugly face is ugly no matter how symmetrical.
The most beautiful woman have symmetrical faces and bodies. The closer the facial mirror symmetry the more beautiful her face is.
@@cosminvisan520 Beauty lies in mirror symmetry every man knows that. You are confusing what most men get with what most men ideal women is. Most men work with what options they have available to them.
We look for symmetry because we can't think of anything better to do.
Brains that think mechanically, sequentially, and symmetrically look like 3d graph paper.
Unpredictable, abstract brains look like spaghetti.
Wrong. Roundness is there before the ball. In fact no ball is perfectly round but the idea of perfect roundness is there, and was there before. Nature evolves around the rules, nature doesn't cause them 💟
Tell that to Aristotle
roundness in nature are bi product of the laws of physics - planets , stars, bubbles , ripples , tree rings etc
True, the ball has the quality of roundness but is not the roundness itself or the quality of roundness. Something else give it the quality of roundness.
@@tonyatkinson2210 what rubbish is that. Why don't you seek to learn before wanting to teach. The idea always has to be first, as in the intelligible realities before becoming manifest. The quality of roundness does not belong to the laws, unless you can expound and reveal how that be so.
Now you say "roundness in nature " -- you're not saying anything but with a statement like that. What's nature, form, substance, qualia etc.
I know you're a materialists and wow.... bi products. Sure.
@@S3RAVA3LM you know a perfect circle doesn't exist right, not even in the mind. For what would it look like, in the mind if it were perfect?
You can invoke a platonic reality, which I'm not sure you are doing or not, but that is a matter of opinion or taste; not a settled fact
he does not exaggerate.
Symmetry is that you have a Creator and only your Creator can restore everything we ruined.
What creator
No that would be Smooth Brainedness
@@jeffamos9854 the creator of the universe, symmetry of our universe.
Designer, Programmer, Initiator of the Big Bang, The Ultimate Observer, The First Cause, The Unmoved Mover.
The forces are created . Every physical force is contingent on what is not contingent . You can't have an infinite regress of contingent physical forces ..
.
1. Every contingent fact has an explanation.
2. There is a contingent fact that includes all other contingent facts.
3. Therefore, there is an explanation of this fact.
4. This explanation must involve a necessary being.
5. This necessary being is God. (Creator, Designer, Programmer, Initiator, First Cause, Unmoved Mover)
@@jeffamos9854 I supposed you weren’t literally ordered to be a human like everyone else was.
@@HyzersGR Prove you have a good brain yourself.
Not solid, not liquid. Hmmm fluidity
I found faith in God from realizing there existed order.
Simple. God made everything. Everything is synced to work and not.
