thanks for your generosity. the explanation is amazing and it deepened my understanding

So is it just a matter of definition? that's a probing question not an objection because i couldn't grasp the intuition. However, i understood it when i read wikipedia's page about it. the problem is i didn't understand its meaning because i didn't apply it on an example.

i still can't find a use of this .So, omitting the V would just make the coefficient more intuitive, for example alpha being meter cube/ kelvin this points more to a rate which makes more sense.

I was reading about thermodynamics in my textbook wheni came across the following thermodynamics constants: However, i don't understand why did we define 1/V inthe constants. What is the point in doing this?

in your approach why would i need temperature when i could just use pressure difference as a scale of internal energy you said no change in volume and no change in chemical substituents but there is a change of pressure. If i defined temperature to be the average kinetic energy , so simply...

I was reading about thermodynamics postulates when i came over the differnetial fundamental equation: I understand that the second element is just pressure and last element is chemical energy, but he problem is i don't understand what is the use of entropy and how does it contribute to a...

I need to learn much more about fluid dynamics before putting any hypotheses

omit the sentence it is really a just conceptual mistake However, when i searched for turbulent wake i found what nearly matches what i mean (amazing video for example) but it just baffles me why wouldn't my scenario happen: the medium collapse behind the object (equally approching its back...

I think i didn't make my point clear. I mean the speed of the body, if a body moves in a linear motion in air supposing the speed is very high (relative to speed of sound ) near 200 m/s, the collapse of vacuum bubble will depend upon the speed of the object and properties of the medium, if the...

at least it will form eddy currents and vortices with velocity-dependent frequency.I think that if the body moves in a linear motion it will displace a certain volume of fluid and then the surrounding medium will refill the vaccum-like space left behind .this process would form waves (since the...

I have read about doppler effect in acoustics so i searched for the relation ship between wavelength of wave produced by linear movement of body and its momentum along with other dependent variables such as density of fluid (leaving acoustics for a second) and temperature but souldn't find a...

https://www.tandfonline.com/doi/abs/10.1080/09500340.2021.1936245?journalCode=tmop20 i read the wikipedia page but it is too brief if you get what i mean. There are possibly many new polarizer synthesis methods

i found several articles and papers on advanced syntheses but i was thinking of a more systematic course (a boo like course (intro-mechanism-types-synthesis))

I have found a fair amount of sources for studying polarized light but I haven't found sources discussing synthesis of polarizers in detail along with mechanistic discussion.

If there are other valid models of the atom or electron they would probably be more famous and accepted , the standard model is still the most successful in explaining practical phenomena. So, what I am looking for is "attempts" or theories that explain quantum outcomes from a different...
