The recently proposed eight-component relativistic wave equation is applied to the scattering of a photon from a free electron (Compton scattering). It is found that in spite of the considerable …
The transition probabilities for the components of both the Balmer and Lyman ®-lines of hydrogenic atoms are calculated for the nonrelativistic Schr¨ odinger theory, the Dirac theory, and t…
Altimeter adalah suatu alat yang digunakan untuk mengukur ketinggian titik atau lokasi suatu tempat berada. Berdasarkan prinsip kerja., altimeter dapat dibagi menjadi beberapa jenis yaitu altimet…
Tenis meja merupakan olahraga yang digemari oleh hampir semua orang di seluruh dunia. Dimainkan di atas meja yang terbuat dari kayu yang dibatasi dengan net yang berfungsi sebagai pembagi meja menj…
We present a brief review of elliptic motions using the mathematical definition of ellipses and the Euler-Lagrange equations of motion. Some examples of elliptic motion in physics, such as Kepler…
Using a theorem of partial differential equations, we present a general way of deriving the conserved quantities associated with a given classical point mechanical system, denoted by its Hamiltonia…
We discuss the relation between classical and quantum physics using the algebraic structure of canonical transformation. The simplest relation between canonical transformation algebra and compact L…
We present the rules of Fourier transforms for one-point, two-point (propagators) and three-point (vertices) Green's functions. The configuration space representations of Green's functions are very…
We present an alternative way to derive momentum representation Feynman propagator in quantum field theory. Instead of using the usual way of vacuum expectations of time-ordered product, we use the…
