Of course the modern mathematical analysis (Calculus) is a very powerful tool in Physics, and even more, for an example what a meaning of area inside of the closed complicated line without it? But the question was about words what we are saying to obtain some formula in the particular case, when...

Is the case is case of we approximating ellipse with a circle and saying that the result area is true for the all ellipses, this means we can avoid some mathematical analysis theorems (me poor knowledge in mathematical analysis)? We can scribe that ##MM' = \widehat{MM'}##, and the height ##h...

I have a lot of questions as usually, but must begin with the difficult to understand moment which have started my explorations of the Kepler's second law. In the book of Steven Wainberg "To Explain The World", in the technical paragraph twenty one I have found the next formula which represents...

In this case must be logical connection: ##\large \text{the reason} \longrightarrow \text{an action} ##, and will be very good to say something about the reason to person the post of which you are banned, this will greatly help to check it's accuracy. 1) And why over the text field on your forum...

Greetings! I have created topic to help myself with understanding of Doppler's effect in Classical Mechanics — Help with understanding the Doppler effect, and after some users provide me with interesting information and showed me my primitive mistake, I have rework my understanding of Doppler's...

The classical mechanics is good description of realitity too, and there is no reason to give any connections to the non-classical theories, it's just specualtions and play with words. Anyway I have understand my mistake, which was obvious but I have created a new physics on it... :)) Anyway it...

Well actually you are saying truth about the similarity of the cases! Wery many thanks! You the first which helped to understand, on other forum me get topic deleted! The was my mistake... Very good, know I can continue the studies. This forum is indeed useful! Again many-many thanks!

You are again incorrect, I am saying we have reach the crucial point the investigation of which will decide who is more close to reality! I will better make a picture, one moment. Just go to the outside of the house for a sec...

Or we can forgot about uncle Lorentz so we no need transform anything to 'approximately equal' and not typing such things, and just pary for holy Galeleo... And this is the reason why 'switch on' of' Doppler's effect in the model destroying relativity. You se the change of the invariant is...

The relations ##\large M \longrightarrow S ## and ##\large S \longrightarrow M ## is NOT the same. Assymetry, viola, the end of relativity of inertial frames in case of Doppler's effect. The ienrial frame of reference is the inertial frame of reference, the changing of wavelength is an invariant...

Grr! What kind of thought lead you to such conclusion? All things you have named is actually have the same meaning in the classical case. I have provided example of the brick which is splinted into two pieces durring free fall, it is an event, in classic and in the SR kinematics. The relativity...

And your medium relative to what? Oh my god... We have closed, defined system: medium, source, observer. On this system we using Galelean transformation, the end. You can imagine it abstractly — expand the medium to the size of the Universe! 😒

You are literaly cannot read the name of topic, which is called 'classical Doppler effect', the classical mechanics is a complited self-defined theory, Galelean transformation is no need any Lorentz's transformation to describe the the classical casess. So in the name of WHAT you continuously...

And that is the reason! I just distracted by the nonsense which is typing the other users, or at least I think it is nonsense... So maybe. 😰 The problem the length is not the speed, the wavelength. Okay, let's measure the wavespeed, in my frist post it's ##\large \left(c + v \right) ##. Of...

The speed of wind is not connected to the wavelength of wind, and wavelength is and invariant. Do you understand that wavelength is the same as mass, as volume, I don't know, as the time interval in the classical mechanics? At least me understand this (if I am wrong, correct me). So your wind is...
