There’s is an inproper rotation S for the Q right. If you rotate 180 degrees through the axis pointing to you out of the screen (the dot in the middle of the Q being the tip of the arrow pointing towards you) the little line of the Q is in the top left part of the circkle inverting through the center brings it back to the right bottom. 4:27

I would pre-heat the oxygen and fuel molecules electromagnetically. Then record the 3D volumetric temperature distribution, tracking flow of reactants. To start. And find the temperature dependent heat capacities data or models. To start. Calibrate and optimized the linked models. Track spectroscopic IR, VIS, thermal, UV, whatever is available. Share the results. Richard Collins, The Internet Foundation

I knew it I fricking knew it my teacher teached bad but didnt now this bad he put in his written book and explanation thatdA=---PdV-SdT when it should be dA=+++++PdV-SdT idk why he wrote he even deducted from dU=dq-dWr which is wrong too,i dont even know why because he used dU=dqr+dWr when using for gibbs so idk why he did different with helmholtz , so is not because he didnt use standar because he did but suddenly changed idk why

I think you should change 3/2 when calculating avg speed for $N_2$ because we do not have singular atom gas but dual atom gas which have 5/2 degress of freedom in normal temperatures and 7/2 in high temperatures

Thank you for the lecture. 6:00 For large n, DeltaE/(h.c) = nu_e - 2(n+1)x_e.nu_e would get close to zero, and then negative. I suppose the model of harmonic oscillator with anharmonic correction becomes incorrect long before that? At 9:50 as you remind us, there is a very low population for higher vibrational states, can we even measure transitions to/from higher values of n ?

Hallo sir ! Unfortunately, in general, neither symmetric nor anti-symmetric wavefunctions can be said to be eigenfunctions of the Hamiltonian. The wave function for an electron in a hydrogen-like atom with atomic number Z in the ground state is RZ(r)=2(Z/a0)^(3/2)*exp(-Zr/a0). RZ(r) is an eigenfunction of HZ=1/(2m)*p^2-Ze^2/(4πε0r). But RZ(r) is not an eigenfunction of HZ'=1/(2m)*p^2-Z'e^2/(4πε0r), Z'≠Z. Let us consider the case where a hydrogen-type atom with atomic number Z and a hydrogen-type atom with atomic number Z' are sufficiently separated from each other. And each electron in each atom is in the ground state. The anti-symmetric wave function Ψ={RZ(r1)RZ'(r2)-RZ(r2)RZ'(r1)}/2^(1/2) is not an eigenfunction of the Hamiltonian H=1/(2m)*p1^2-Ze^2/(4πε0r1)+1/(2m)*p2^2-Z'e^2/(4πε0r2). It should be an ironclad rule of quantum mechanics that the wave function is an eigenfunction of the Hamiltonian.

Why do orbitals have to assume spherical harmonics? There is no preferred axes to a hydrogen atom upon which one has to introduce a natural spherical coordinate system. The 'according to Hoyle' approach is to base orbitals on spherical harmonic forms of wave functions, then fudge it when talking about hybridization. But the hybridized arrangement like one finds for Carbon or Oxygen is more symmetrical and one could use a function that satisfies the Schroedinger equation for this orbital structure with its own associated energy level. It would be a superposition of an infinite number spherical harmonic wave functions, but this simply reflects the change in coordinates from spherical to one that more naturally accommodates the 4-lobed Carbon orbital structure. Perhaps spherical radial basis functions can match this structure.

Thanks for your interesting video. Area under a curve is often equivalent to energy. Buckling of an otherwise flat field shows a very rapid growth of this area to a point. If my model applies, it may show how the universe’s energy naturally developed from the inherent behavior of fields. Your subscribers might want to see this 1:29 minutes video showing under the right conditions, the quantization of a field is easily produced. The ground state energy is induced via Euler’s contain column analysis. Containing the column must come in to play before over buckling, or the effect will not work. The sheet of elastic material “system”response in a quantized manor when force is applied in the perpendicular direction. Bonding at the points of highest probabilities and maximum duration( ie peeks and troughs) of the fields “sheet” produced a stable structure when the undulations are bonded to a flat sheet that is placed above and below the core material. Some say this model is no different than plucking guitar strings. You can not make structures with vibrating guitar strings or harmonic oscillators. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wrBsqiE0vG4.htmlsi=waT8lY2iX-wJdjO3 At this time in my research, I have been trying to describe the “U” shape formed that is produced before phase change. In the model, “U” shape waves are produced as the loading increases and just before the wave-like function shifts to the next higher energy level. Over-lapping all frequencies together using Fournier Transforms, can produce a “U” shape or square wave form. Wondering if Feynman Path Integrals for all possible wave functions could be applicable here too? If this model has merit, seeing the sawtooth load verse deflection graph produced could give some real insight in what happened during the quantum jumps between energy levels. The mechanical description and white paper that goes with the video can be found on my LinkedIn and RU-vid pages. You can reproduce my results using a sheet of Mylar* ( the clear plastic found in some school essay folders. Seeing it first hand is worth the effort!
