(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!

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.

[@cxiliapersono]

@@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).

[@LuisAldamiz]

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).

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 used the Inverse Square Law when lighting shots a a cameraman for the news.

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

Roger Onslow Exactly the same reason. Permittivity is also related to spherical symmetry.

[@nanigopalsaha2408]

@@rogeronslow1498 Actually, It comes from the Ampere-Maxwell Equation, where we deal with the curl of a vector field . Since the curl deals with circumferences, for symmetric fields around a closed circular loop, the circumference is 2pi*r, which gives the pi to the constant known as permeability of free space.

Eagerly waiting for the gravity-electricity analogy :)

[@ffggddss]

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

[@ScienceAsylum]

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.

[@ffggddss]

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

[@ScienceAsylum]

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.

[@ffggddss]

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
