cool stuff!

Shouldn't the tangent and normal vectors span the osculating plane?

Thank you for these deep dives. As an amateur physicist, I really appreciate these videos, i always wanted to go deeper in these topics. My next vacation i will spend going through all you videos.

Dirac and Lorentz Transformations Dirac took an electron and figured out how the electron will transform under the Lorentz transformations and after published the results as the existence of an antielectron / positron. Electron after Lorentz transformations changes into an antielectron.

This looks like a very valuable resource...but you mention that is the follow up to a preceding video that should probably be viewed first. Can you direct me to the preceding video? If the videos were numbered sequentially It would be a great help. Thank you.

Hi, the videos are great. I have one comment. isn't F^(23)=Bx rather than -Bx? I get all signs opposite.

Schwarzschild literally translated is Blackshield. So Germ. black is schwarz ( no c for the sh sound in Engl. -> shwarz) and Germ. shield is Schild, pronounced shild like built, no eye sound of the i, but a „kill“ sound. The d at the end is a soft „d“ sound in principle, but in everyday German it is spoken as a sharp „t“ sound like in English. So Shwarzshilt. Similarly Rothschild isnt pronounced Roths-child, there is no child involved here, but roatshild/roatshilt. Roth ( with an ancient German th, the h is preserved in names only and always silent in German) is German red, in modern German rot ( no name, no h), so you have Blackshield ( Shwarzshilt) and Redshield ( Roatshilt), two jewish names that were chosen by them because in the middle ages in Germany some (their) houses had a coloured shield at the front wall of the house. Legend has it that Rothschild ( Roatshilt ;) started with this. So due to your pronouncing Ricci in Italian I thought that could be of interest to you. Good videos you make!

Topological holes cannot be shrunk down to zero -- non null homotopic. The big bang is a Janus point/hole (two faces = duality) -- Julian Barbour, physicist. Positive curvature is dual to negative curvature -- singularities (points) are dual. Synchronic points/lines are dual to enchronic points/lines. "Always two there are" -- Yoda. Real is dual to imaginary -- complex numbers (photons) are dual. Space is dual to time -- Einstein.

Holy reverb batman

Very clear thank you!!

For 118 years, by determining the constancy of speed of light, all experiments and Michelson-Morley experiments are indirect and incomplete. If the Michelson-Morley experiment was carried out on a bus or airplane and was used to determine speed. only then will this experience be direct. Therefore, Einstein does not rely on the Michelson-Morley experiment. Question. Do you have an example of such direct experience? New technologies, new research tools Let me suggest for schoolchildren and students on one's own to measure the Universe, dark energy, black holes, etc. To do this, I propose two practical devices. «laser tape measure *+reference distance* 1,000,000 m”» and «Michelson-Morley HYBRID Gyroscope». I am writing to you with a proposal for the joint invention of a HYBRID gyroscope from non-circular, TWO coils with a new type of optical fiber with a “hollow core photonic-substituted vacuum zone or (NANF)” where - the light travels 500000 (In a laser tape measure, the length of the optical fiber is fixed at 1000000 ) meters in each arm, while it does not exceed the parameters 94/94/94 cm, and the weight is 94 kg. Manufacturers of “Fiber Optic Gyroscopes” can produce HYBRID gyroscopes for educational and practical use in schools and higher education institutions. Einstein dreamed of measuring the speed of a train, an airplane - through the Michelson-Morley experiment of 1881/2024, and only then would the experiment be more than 70% complete. This can be done using a fiber optic HYBRID gyroscope. Based on the completion of more than 70% of Michelson's experiment, the following postulates can be proven: Light is an ordered vibration of gravitational quanta, and dominant gravitational fields adjust the speed of light in a vacuum. you can make scientific discoveries; in astronomy, astrophysics, cosmology, higher theoretical physics,...

Wow...now i have more clarity

great review, thanks!

What does it mean F ^dA mean

Brother, you are doing wonders for the community. Keep going.

Nice 🎉

I appreciate your effort 🎉 But currently I am not able to understand such complex stuff 😅

Can i please ask, why biophysics? Why not mathematical or theoretical physics? Im doing a double major math physics and was thinking complex system for grad school

i think you have a typo at 23:30. that "-" sign should be a "+"

Keep going buddy😊😊

What are prerequisites for yang mills theory

Very nice

Just got silver membership

As always...thank you so much

I have a few imagination of ideas can I share with u!!!

Appreciate it. I've wanted to get into statistical fields for a while. I've been trying to follow Kardar's lectures and books re: this topic. Do you think that's wise, or is there a better alternative?

great video...once again

I can follow the consequences, but I missed the very original motivation for assuming electrons to be represented by a delta function. What was the motivation? Experimental or what?

Quite an interesting topic. Just a small suggestion, it would be easier to follow if your voice is a little more clear. Cheers!

Hi Tristan, I’m an undergraduate physics and astronomy major and would love to continue studying particle physics and quantum gravity. Finding this channel has been an absolute godsend! I might be a year or two off from actually understanding anything from these videos but knowing that this all exists to come back to is amazing for me. Keep up the great work!

Very nice. Just a question: it seems to me that what you are doing when relating i with the matrix, is simply defining the matrix bold(i)? I cannot see how you can equate i (the number) to a matrix. You say you have a transformation, but I see no transformations. Could you clarify this?

When I start to imagine about how the space can expand I understand that there is something strange, because it expand everywhere at the same rate in all directions, it’s like a fractal of expansion but everywhere. But this kind of thing would result in an infinite speed of expansion. Space time is quantum I think

yes, and uh, from the popcorn model of reality: make the universe manageable by applying simplicity. our universe can be divided into 2 parts. the beginning and the end (dissipation). now imagine a higher pitched harmonic of our reality: This is the realm of dark matter. the ratio in the relative energy difference between the adjacent harmonics has a magnitude of between 10e64 and 10e72 7 levels of force exists within these harmonics: time* gravity weak strong em human thought process* big (supreme)* *not recognized as a force our universe exists from the interaction of these forces em is the dominant force in our measured universe. the most massive dark matter particle is equal in mass to the least massive detected particle pair (neutrino/antineutrino). shall i go on in a different post or continue here or just shut up?

I’m high as shit

Quantum gravity is interesting. But one can also look at it like as it expands it is taking away from space. Thomas Bram author of The Woven Sun

Hey that's pretty cool. I don't really know much about physics, but are the params in the matrix related to christoffel symbols?

🎉

Hello. For big science, do we need direct experiments with direct proof of the constant speed of light? Who will help create a working group involving students to work on a new experiment? Do you understand that one mind and a person are not enough? (for 119 years) By determining the constancy of speed of light, all experiments and Michelson-Morley experiments are indirect and incomplete. If the Michelson-Morley experiment was carried out on a bus or airplane and was used to determine speed. only then will this experience be direct.

(We are not looking for ether, we will see the work of gravitational quanta) The result is a «theory of everything» in a simple teaching device and a new tape measure for measuring the universe.

Title: "Information-Based Quantum Gravity Effects" Prediction: Gravitational effects have a quantized structure at very small scales, with the quantization related to fundamental information units. Experiment: Design high-precision interferometry experiments to detect minute variations in gravitational fields that correspond to these proposed information quanta. Impact: This could provide the first experimental evidence linking quantum gravity to information theory, potentially bridging quantum mechanics and general relativity. This framework will aim to link quantum information theory with gravitational effects at the Planck scale. 1. Fundamental Assumptions: a) Information is quantized at the Planck scale. b) Spacetime has a discrete structure at the quantum level. c) Gravity emerges from the dynamics of quantum information. 2. Mathematical Formulation: Define an information quantum (infobit) ι as: ι = √(ℏG/c³) = l_P Where l_P is the Planck length, ℏ is the reduced Planck constant, G is the gravitational constant, and c is the speed of light. 3. Information-Spacetime Relationship: Propose a relationship between information content and spacetime curvature: R_μν - (1/2)Rg_μν + Λg_μν = (8πG/c⁴)T_μν(I) Where R_μν is the Ricci curvature tensor, R is the scalar curvature, g_μν is the metric tensor, Λ is the cosmological constant, and T_μν(I) is an information stress-energy tensor. 4. Information Stress-Energy Tensor: Define T_μν(I) as: T_μν(I) = (ℏc/l_P⁴)(∂_μI ∂_νI - (1/2)g_μν(∂I)²) Where I is the information field, a scalar field representing the distribution of information in spacetime. 5. Quantized Geodesic Equation: Propose a quantized version of the geodesic equation: d²x^μ/dτ² + Γ^μ_νρ (dx^ν/dτ)(dx^ρ/dτ) = (ℏ/m²c)∇^μI Where Γ^μ_νρ are the Christoffel symbols, τ is proper time, m is the mass of a test particle, and ∇^μI represents the covariant derivative of the information field. 6. Information-Mass Equivalence: Postulate an equivalence between mass and information: m = (ℏ/c²)I This suggests that mass can be viewed as a measure of localized information content. 7. Quantum Information Metric: Define a quantum information metric: ds² = g_μν dx^μ dx^ν + (l_P²/ℏ²)dI² This metric incorporates both spacetime intervals and changes in information content. 8. Information Uncertainty Principle: Propose an information-based uncertainty principle: ΔI · Δτ ≥ ℏ/2 Where ΔI is the uncertainty in information content and Δτ is the uncertainty in proper time. 9. Predictions: a) Spacetime Foam: At the Planck scale, spacetime should exhibit quantum fluctuations with amplitude ~l_P and frequency ~c/l_P. b) Information-Induced Gravity: Regions of high information density should produce measurable gravitational effects. c) Quantized Black Hole Entropy: The entropy of a black hole should be quantized in units of ln(2), reflecting the discrete nature of information: S_BH = k ln(2) · (A/4l_P²) Where A is the area of the black hole's event horizon. d) Information Loss Paradox Resolution: Information is conserved in black hole evaporation due to the fundamental nature of the information field. 10. Experimental Implications: a) Gravitational Wave Spectrum: Predict a characteristic spectrum of high-frequency gravitational waves due to Planck-scale information dynamics. b) Vacuum Energy Fluctuations: The vacuum energy should exhibit quantized fluctuations related to the information content of space. c) Quantum Gravity Corrections: Predict specific corrections to the gravitational force at very short distances due to information quantization. This theoretical framework provides a mathematical foundation for linking quantum information theory with gravitational effects. It offers several testable predictions and potential resolutions to long-standing problems in quantum gravity.

Good luck with this

Which is the best book for quantum field theory sir?

nice video

Kerr to Schwarzschild to white transition during the thermal death

Great

So basically what you're saying is that by adding the Lagrangian related to the photon field to the Lagrangian related to the Dirac field we can get a locally invariant form of the Dirac Lagrangian. So photon field is required in order to have the local invariance holding for the Dirac field. Nice - so we need photons (photon field) in order to make the Lagrangian corresponding to spin 1/2 particles locally invariant, right?

@CryoScience Thanks for another great video, but one quick point and a question - what justifies the substitution of ck in for omega at 17:33 ? The subsequent equation suggests that m = 0 (which means this reduces to the non-dispersive case). Also, the plot of c vs. k around 20:35 shouldn't be linear. Many thanks for the series!

Talk about polluting science. I believe the term safe and effective a couple years ago set the science community and of course the medical community back very far. When she with us somebody blatantly lying to you tend not to believe anything they say.
