Physics of today is in a chaotic situation. This sitation is explained in the book as caused by our confusions regarding the relation between mathematics and physics, and also by our bad understanding of the wave model for light. It is demonstrated that a correct application of the wave model means, that the particle model for light is not needed, and that using wave model only means that we can get rid of the absurdities in physics of today, However, we need the ether, and particles may be needed for describing the ether. The book denonstrates that the confusion in physics is older than generally assumed.
