In this paper, we are going to rely on the first law in physics through which we can obtain a precise ideal value of the universal gravitational constant, a thing which has not happened so far. The significance of this law lies in the fact that, besides determining a precise ideal value of the gravitational constant, it connects three different physical disciplines together, which are mechanics, electromagnetism and thermodynamics. It is what distinguishes this from other law. Through this law, we have created the theoretical value of the gravitational constant Gi and we found it equivalent to 6.674010551359 × 10-11 m3·kg-1·s-2. In the discussion, the table of measurements of the gravitational constant was divided into three groups, and the average value of the first group G1 which is the best precision, equals the following sum 6.67401×10-11 m3·kg-1·s-2, and it’s the same equal value to the ideal value Gi that results from the law, as shown through our research that any other experimental values must not exceed the relative standard uncertainty which has a certain amount that is equivalent to a value of 5.325×10-5 and that’s a square value of the fine-structure constant.

In the theory of general relativity, the finding of the Einstein Field Equation happens in a complex mathematical operation, a process we don’t need any more. Through a new theory in vector analysis, we’ll see that we can calculate the components of the Ricci tensor, Ricci scalar, and Einstein Field Equation directly in an easy way without the need to use general relativity theory hypotheses, principles, and symbols. Formulating the general relativity theory through another theory will make it easier to understand this relativity theory and will help combining it with electromagnetic theory and quantum mechanics easily.

This paper research is the first part of the scientific theory that seeks to unify the sciences of physics with the minimal number of mathematical formulas as possible. We will prove that all equations of forces in nature can be concised in two mathematical formulas, no difference between gravitational or electrical forces or any other type of Types of conventional forces, and through the equivalence of the concepts of matrix and vector, in this theory we will be linking the four-dimensional forces equations with the classical physics as an introduction to connect the rest of the physical sciences.

superconductor samples of type (CoFe2O4)xGdBa2Cu3O7-δ (0≤x≤0.1) were synthesized by the conventional solid-state reaction technique, whereas nanosized CoFe2O4 was prepared by co-precipitation method with grain size of about 8.5 nm. The elemental content of the prepared samples was determined using particle induced X-ray emission (PIXE). The temperature dependence of real (χ') and imaginary (χʺ) components of AC magnetic susceptibility (ACMs) at different magnetic field amplitude (3–15 Oe) was investigated. The analysis of the temperature dependence of ACMs was performed using Bean critical state model. The values of the critical current density J c at T > T p (T p is the inter-granular loss peak temperature) were calculated as a function of magnetic field and nanosized CoFe2O4 content. It was found that the low nanosized CoFe2O4 addition content (x = 0.01) improves the critical current density J c of Gd-123 superconducting phase. The observed variation of J c with temperature indicated that the weak links are changed from superconductor–normal metal–superconductor (sNs) for free sample to superconductor–insulator–superconductor (sIs) type of junctions for samples added with nanosized CoFe2O4 of x > 0.01. We also discussed the experimental results in the framework of the critical state model to estimate the effective volume fraction of the grains f g using Cole–Cole plots.

In this paper, we are going to find out a simple way yet extraordinary to the equation of motion of electric charge under the influence of a central force. We’ll find that it is the same as the formula of the common equation of motion in the theory of general relativity which controls the motion of planets around the sun;thus, every electron orbiting around the nucleus has a perihelion which revolves same as Mercury perihelion yet faster 2000 times according to Hydrogen atom, assuming that hydrogen has a perihelion. That is to say, when Mercury perihelion takes three million years to complete a full cycle around the sun, we find that Hydrogen perihelion (here we mean the classical model of atom, not quantitative model of it) revolves around the nucleus at 1.05 × 1012 cycle per second. In addition, the radiation passing near the nucleus deviates same as the deflection of light passing near the sun yet with a greater value according to how close the radiation is from the nucleus, as shown in the discussion. We discussed briefly (but differently) the definition of black holes to affirm symmetry principle between the atomic and astronomical models. symmetry in equations of motion of a body in the atomic and astronomical models indicates that the Advance of Mercury’s Perihelion, deflection of light passing near the sun, and the definition of black holes are the ABCs of classical physics;however, they are not considered as reliable evidences on the soundness of the principle on which the theory of general relativity is built on, in the presence of a contradiction between the definition of gravity in the general relativity and in the electromagnetic theory.

Maize leaves are produced from polarized cell divisions that result in clonal cell lineages arrayed along the long axis of the leaf. We utilized this stereotypical division pattern to identify a collection of mutants that form chloroplast pigmentation sectors that violate the clonal cell lineages. Here, we describe the camouflage1 （cfl） mutant, which develops nonclonal, yellow-green sectors in its leaves. We cloned the cfl gene by transposon tagging and determined that it encodes porphobilinogen deaminase （PBGD）, an enzyme that functions early in chlorophyll and heme biosynthesis. While PBGD has been characterized biochemically, no viable mutations in this gene have been reported in plants. To investigate the in vivo function of PBGD, we characterized the cfl mutant. Histological analyses revealed that cfl yellow sectors display the novel phenotype of bundle sheath cell-specific death. Light-shift experiments determined that constant light suppressed cfl sector formation, a dark/light transition is required to induce yellow sectors, and that sectors form only during a limited time of leaf development. Biochemical experiments determined that of 1 mutant leaves have decreased PBGD activity and increased levels of the enzyme substrate in both green and yellow regions. Furthermore, the cfl yellow regions displayed a reduction in catalase activity. A threshold model is hypothesized to explain the cfl variegation and incorporates photosynthetic cell differentiation, reactive oxygen species scavenging, and PBGD function.
