10.4.3 Two basic differences in formal logic

    Without doubt,accompanied with a series of crucial idea or cognition variations appearingin lots of most basic physical concepts,the mathematical characters or logic connotations of therelated formal systems will unavoidably take some important and essent...[继续阅读]

11.5.2 Curved wave trace

    As a general or common character of every wave movement everyone may reasonablyaccept,provided a background field can be approximately regarded as homogenous,any smalldisturbance appearing in the homogenous field will propagate over all the space in a nea...[继续阅读]

5.1 Initial investigation on material foundation of “displacement current”

    In principle,any reasonably existing formal system as well as all the formal quantitiesshould be regarded as some artificially idealized creation,for it is always impossible to exhaustall the truth of the existing-in-itself material world. However,to any ...[继续阅读]

9.1.3 Counter examples of the classical definition of wave

    We will find that,when restricted within electromagnetism,the wave equation constructedby a special differential operator called as bispinor,▽×▽×,which greatly differs fromLaplace’s differential operator ▽2 presented in the generally said wave equation(9....[继续阅读]

1.1.1 Clarification on the “finite discourse universe” of classical electromagnetism

    When any special science proposition is discussed,it is always necessary to primarilyconstruct a finite discourse universe or discussion domain,which maybe coincides in somedegree with the category said by Cant. Of course,the finite domain of a theoretica...[继续阅读]

9.3.1 Objectivity of bispinor wave equation

    First,so as bispinor operator that should be regarded as an objective differential operator,the appearance of a bispinor wave equation should also be understood as a natural andunavoidable phenomenon in logic,while the electromagnetic waves we study are j...[继续阅读]

11.1.3 Empirical energy transformation and conservation law becoming a unique proper bridge to connect different material existing forms

    The energy of a material set may be regarded as a proper measurement of the capability forthe material set to make movement. Both the movement of material and material at movementare as two sides of same a thing or as a dialectical unity of two sides reli...[继续阅读]

7.7.1 Reasserting Ψ but B to be as a proper formal quantity

    Worth to repeatedly point out that,though maybe regarded as solvable,the boundary valueproblem (7.6.4) that only takes the rotation of a vector function as a physical quantity weshould solve would not be a proper mathematical proposition. The reason is th...[继续阅读]

Chapter 5 Discriminations on displacement Current——Exploration into the real connotation hidden in the false assumption

    In the classical theory of electromagnetism,both the E and B,which should logicallyconnect with a certain force that is formally defined as the product of mass and acceleration of abody,have been customarily regarded as two basic dependent variables. But,...[继续阅读]

5.1.2 Rethinking on a derived nonzero E

    Once a uniquely given current source changed from a static unvarying state into anotherdynamic varying state,the electromagnetic field excited by the singular current source willpresent a nonzero E. Why is it? Or what will the real physical mechanics be?S...[继续阅读]
