ABSTRACT: Physical constants such as Gravitational Constant (G) and Planck Constant (h) are constant quantities. They don't change with anything at all, no matter of the observation reference points and gravitational fields. However, the number and unit components of the physical constants measured at various reference points are different, subject to the local gravitational field and aging of the universe at the reference points (such as on earth). These can be proved by the calculation of Gravitational Constant from Newton's Law of Universal Gravitation and Newton's second law of motion, and Planck constant from photon momentum and wavelength.......

Keywords: Physical Constant, Gravitational Constant, Planck Constant, Wu Constant, Wu Spacetime Constant, Physical Unit, Wu's Spacetime Transformation, Wu's Spacetime Equation, Wu's Spacetime Field Equation, Einstein's Field Equation.

ABSTRACT: In the vast tapestry of the physical world, few phenomena capture the imagination quite like liquid crystals. Bridging the realms of order and chaos, these curious substances defy conventional classification, exhibiting properties reminiscent of both liquids and solids. In this article, we embark on a journey through the captivating realm of liquid crystals, exploring their structure, behavior, applications, and the profound impact they wield across various fields of science and technology......

ABSTRACT: Sections of one conductor with alternating electric current located at a short distance, separated by electromechanical contacts, repel each other. The force of interaction is proportional to the square of the current and is quite large at high frequencies of alternating electric current. This is only possible if the conductor has a surface electric charge.

KeyWords: Alternative current, Charge, Frequency, Weight of conductor, Metal electrodes, Electric field

ABSTRACT: CdSe doped with Mn+2 ions in the range 1,3,5,7 and 9 at. % thin films were synthesized on to ultrafine ITO substrates by Successive Ionic Layer Adsorption and Reaction (SILAR) technique and studied the nanostructures, micro-strains and stress and dislocation density in the films using XRDand SEM techniques. Xray diffraction results in the films showed cubic zinc blend structures with preferential reflection along (210)- 1at.%, (110)-3at.%, (200)-5, 7 at.% and (110) -9 at.% of Mn+2 ion concentrations. The observed lattice parameters a and d – values.........
