Man, i swear that every time i watch one of your videos, there's at least one "ohhhhhhhh NOW i get it" moment, even (or especially, actually) if the video is on a topic i've watched plenty of other stuff about. (This time it was the 4π being included in the constant - i'd always wondered why it just disappeared!) There are plenty of other really great science KZbinrs, but you have a real knack for explaining difficult concepts without dumbing them down, and for somehow just making things click. Keep up the good work - you're doing a really wonderful job!

Dude, you are starting to beat out PBS Spacetime for my daily KZbin "science fix". I still love that channel, but your topics are consistently educational. Even if I'm already familiar the subject matter, you have the wonderful habit of striving for the most accurate models, metaphors and analogies while minimizing the use of and/or correcting models that are inaccurate or oversimplify the subject matter. This makes even well known topics seem fresh and exciting! Thank you and please...Keep up the good work!

@@justasaiyanfromearth5252 Well, it applies to "formal systems", where you assume axioms and go ahead with rules. You could call the Fundamental Laws of Physics "axioms" and then go ahead with "math as usual" (which can be as complex as you like, the likes of Whitehead and Russell's "Principia Mathematica"). Furthermore, Gödel's argument hints a "recursion problem" on the diagonalisation. There may as well be an undemonstrable conjecture upon information itself within our universe, which could forbid us from unifying the very same rules we're trying to tackle (and use as a tool to do so).

Great, I suddenly grasped better than ever before where the concept of "fields" comes from and why it is so central to modern physics. Good job, Gauss! And also why it is so central to unification theories such as QFT. As for your question, I think we'd get to some sort of unification soon-ish, i.e. not too soon because of the excessive weight of QM-based ideology but soon-ish enough because that hegemony of QM, which IMO acts as blinders, is collapsing as we speak. My hunch is that rather than trying to reform GR to the QM mold it is rather the opposite what must be done somehow, and that QFT itself is a step in the right direction, i.e. less "point particles", more wavefunctions in fields, fields that incidentally are not distinct from space-time except in their way of "bending" or "vibrating". In other words the curvature of space-time is the wavefunction of gravity and the "particle's" wavefunctions are the curvature of the other three (or two) forces, just that one is "extense" and the other "intense" but both are "tense", i.e. some sort of "tensions" (describable surely by tensors) in space-time. This regardless of whether space-time itself is quantized (as it seems) or not: the Plank-sized space-time may be the quantum of uncertainty but it's not enough in itself to explain neither gravity nor QM, it's just the quantum of the field(s).

Their early work was a little too gravitational wave for my tastes, but when Sputnik came out in '83, I think they really came into their own model, commercially and artistically. The whole theory has a clear, crisp sound, and a new sheen of consummate professionalism that really gives the ecuations a big boost. He's been compared to Stephen Hawking, but I think Huey has a far more bitter, cynical sense of humor.

I used the Inverse Square Law when lighting shots a a cameraman for the news. Say the news anchor wants to do a slow walk towards the camera, but because they're also walking towards the light they will get brighter too. I use the principle of the Inverse Square Law (I don't do the math) to light them evenly as they move along the Z axis of the camera view. Moving the light backwards reduces the rate of the light drop-off, very useful

Liked and shared. Love the way you explain things. As far as a theory for everything, I think the more we learn the more questions we will unturn. We will never be satisfied, and that's a good thing. Once we unify all forces and conquer the singularity, we will have even more questions than before. We will never know everything, but think about it. If we did get to that point, where would we go from there? Humans need mysteries, we thrive on figuring things out. Curiousness and consciousness are the real mysteries...

I just came back to this masterpiece having realized that electric potential does NOT follow the inverse square law! "It comes down to power and energy. Power is ultimately the thing that counts and as power spreads across a sphere of increasing size, geometry shows us that the power density goes down by 1/r2. Following through with this, we see that the amplitude of the electric field decays with 1/r2. Electric potential is calculated by integrating the electric field and the integration of 1/r2 leads to a 1/r relationship."

We could just redefine all units to make pi vanish (less constants).

Another good one! A few things that I noticed/thought of during it: 1. 5m 26 - 44s: In your animations of grav & E-field vectors, from Earth/charge q wandering through space - for the Earth-grav case, the arrows should point *inward.* [EDIT: Oops! I see you've already said so yourself, in Comments.] 2. 6m 40s: So was it Heaviside (1885) who put the EM laws into vector form? - That *was* a big deal, but it was J. C. Maxwell who, two decades earlier, actually first wrote the EM laws, unifying electricity & magnetism. 3. 7m 36s: In your answer, at the end, about gravitons "escaping" a BH, another way of putting your answer is, that in order to even *have* gravitons, you must already have a quantum theory of gravity, which we don't yet have. To imagine QM particles moving in a non-QM grav field (of spacetime curvature), is erroneous from the get-go; especially when the field being quantized to make those particles, is the very same spacetime-curvature field. Stay nutty! [Make mine cashews, please...] Fred

1. Yes, I already corrected this (as you noticed). 2. Yes, the way Maxwell wrote the equations was a complete mess. There were a total of twenty. Heaviside turned them into vectors and reduced the equations from 20 to 4. Heaviside was brilliant, but also had no people skills so everyone hated him. 3. I will do a video on gravitons eventually.

1. Appreciated. Perhaps the most singular feature of science, is its insatiable appetite to correct itself. And your exemplification of this, is one reason I like your channel so much. 2. Then shouldn't we also credit Einstein (or whoever did this, after SpecRel was published) for simplifying Maxwell's Equations even further, to 2? To wit: d *F* = 0 d **F* = **J* where *F* is the Faraday 4-tensor, which is antisymmetric and contains the 3 E- and 3 B-field components; and *J* is the charge-current 4-vector. 3. I surely want to see that when it comes out. The graviton is a particle that *must* exist, and we even know what some of its properties must be, but we can't yet figure out how to tease it out of the theory, because we don't yet *have* the theory it would come out of. So doing a video on that will be a real challenge, I'd have to say. I'm looking forward to hearing the latest ideas from theorists working on QG, an area I confess I haven't kept current on. Fred

2. Unfortunately, while important for a deeper understanding, the tensor form barely ever gets used. _Use_ plays a big factor in how things get named. In fact, a lot of laws are named after the first people who used them rather than the people who developed them.

Yep, math and physics, I know, and I'm sure lots of other fields of study, are rife with misnamings. Bode's Law in astronomy, discovered by Titius (& now recognized as such - Titius-Bode Law) Pell's equation in number theory, named (by no less than Leonhard Euler!) for John Pell, who merely revised a translation of someone else's book about it. etc. But from what you say, it sounds like the equations in question should be called the Maxwell-Heaviside equations. (As an aside, did Heaviside generate the differential form of those equations, or the integral form, or both?) BTW, my dad, a career meteorologist whose main contribution to the field was in the delvelopment of numerical models for forecast computation, mentioned Heaviside to me a few times. I wish I could recall in what connection, but I think it had something to do with the governing equations of fluid dynamics - Navier-Stokes, and so forth - so I'm thinking it might have been something similar to the case of Maxwell's equations - i.e., casting them in vector calculus form. But it's striking to me that I got through math & physics in high school, college (math major), and grad school (in physics) without ever once hearing Heaviside mentioned. And one of my dad's longtime beefs was about the ivory-tower, clique-ish mentality of academia; so putting 2 and 2 together, I surmise that Heaviside's work was sort of black-balled by academia. Whatever his people skills were or were not. Fred

Since it's okay to be a little crazy, then here it goes. In quantum mechanics, we quantize forces too, we have done it with Weak, Strong and EM forces, while gravity is yet to be quantized. All these quantizations involve Planck's constant and it kind of works as the scale of our metric. We are well aware how feeble gravity is in terms of strength when compared to the other forces. So here is my proposition, what if we come up with a constant with similar units as the Planck's constant but with a much lesser order, I think then we might be able to quantize gravity as well. In classical mechanics everything appears as a continum as our metric of perseption is way larger than the one those forces have intrinsicly. I am not able to express my idea, but if you are able to get the point do let me know if it is workable or not. -A Crazy undergrad Physicist

I wouldn't really call Planck's constant a "scale." It can only scale things _in combination_ with other constants. I would be more comfortable saying the Fine-Structure Constant scales the quantum world. It also has the added benefit of being unitless (dimensionless). As for gravity, we already have constants for it that give us an idea of its strength.

gravity becomes "quantised" if we consider a quantised time... In loop quantum gravity theories Plank units are "unitary bit" for space and time (c=L/T with L and T plank length and time, while hbar=ML2/T with M plank mass). If we consider a quantised universe (holographic space + quantised time) we can live with 1 real degree of freedom as mass or frequency to account for the total local energy :) I agree a fine structure constant based representation, with no "human chosen" units of measure, will be much more "general"... I believe it's connected with a geometrical problem of angles and perspective from which we look at the gauge bosons effects on reality..a kind of "projection" of e2/q2, where e is the elementary charge and q is the plank charge.. but I still have to figure out all the math...
