One of the challenging riddles that is set by light is: do photons have wavefunctions like other elementary particles do? Wave–particle duality has been a prevailing fact since the beginning of quantum theory thought; in electromagnetism, light is already a kind of undulation, so what about the waves of probability then? Well, Quantum Field Theory...

Science in general must be able to be described in layman. To evaluate the space of an atom, the coherent experiment of absolute zero temperature in physics is the most valuable to prove the fundamental meaning of the quality of space versus the "space" that science doesn't consider a valuable element of the atom. The Bose-Einstein condensate exper...

We explore the duality invariance of the Maxwell and linearized Einstein–Hilbert actions on a non-rotating black hole background. On-shell, these symmetries are electric–magnetic duality and Chandrasekhar duality, respectively.

4th Law of Motion-Unified Interaction Principle (UIP): The 4th law posits that there exists a fundamental force, which we'll call the "Unified Interaction Force" (UIF), that unifies the four fundamental forces of nature (gravity, electromagnetism, the weak nuclear force, and the strong nuclear force). This Unified Interaction Force acts on all part...

Gravitoelectromagnetic analogies are somewhat ubiquitous in General Relativity, and they are often used to explain peculiar effects of Einstein's theory of gravity in terms of familiar results from classical electromagnetism. Perhaps, the best known of these analogy pertains to the similarity between the equations of electromagnetism and those of t...

Na tradição do campo disciplinar da Física, e nos respectivos manuais didáticos, a invariância das equações de Maxwell por transformações de Lorentz é usualmente apresentada via cálculo tensorial, do que decorre que seu ensino seja postergado até que (supostamente) os estudantes-alvo dominem esse formalismo. Isso pode acarretar, em disputas curricu...

In 1919, the mathematician Theodor Kaluza began to play around with Albert Einstein’s formulas for gravity. Out of curiosity, he reworked the equations to see how they‘d look in five, rather than four, dimensions. The exercise yielded an extra set of equations, which were the same as James Clerk Maxwell’s equations for the electromagnetic field. Hi...

A realização de atividades experimentais nas aulas de física é algo considerado relevante por estudantes, professores e pesquisadores.

Physical laws—such as the laws of motion, gravity, electromagnetism, and thermodynamics—codify the general behavior of varied macroscopic natural systems across space and time. We propose that an additional, hitherto-unarticulated law is required to characterize familiar macroscopic phenomena of our complex, evolving universe. An important feature...

Part 4: The Elementary Charges and Particles Electric charge, as we have shown (Barak 2019), is not alien to space, but merely its deformation. Positive charge is a contracted zone of space and negative charge is a dilated zone. The field of an electric charge is a continuation from this zone to infinity, of a diminishing contraction or dilation of...

We consider the Earth moving through empty space at 30 km/s (in the sun’s frame of reference). Associated with this motion is a convective flow of kinetic and internal energy. Since there is high pressure inside the earth, and since the earth is moving, there is yet another “hydraulic” energy flow. This latter is what this article is about. Althoug...

Part 3: Electromagnetism as the Geometrodynamics of Space Light is a vibration (excitation) of the Electromagnetic field, which as we show is Space itself.

Part 2: Our General Relativity Field Equation that Incorporates Electromagnetism All past efforts to unify gravitation and electromagnetism failed because they considered energy/momentum to be the common denominator in this unification. Mass curves space, but nobody knew that charge, as we have shown in Part 1, also curves space. It was naively bel...

Maxwell's theory of electromagnetism is regarded as one of the most important work in mathematical physics. His later work on vortex theory of molecules gives a theoretical framework for biological sciences, as well. With Einstein's insightful look back into his work, unifying theory of relativity with electromagnetism came to be known as the "theo...

For targeted transport in the body, biomedical microbots (μbots) must move effectively in three‐dimensional (3D) microenvironments. Swimming μbots translate via asymmetric or screw‐like motions while rolling ones use friction with available surfaces to generate propulsive forces.

One of the main aims of theoretical physics is a unification of gravity and electro-magnetism, that is, a description of gravity and electromagnetism in the framework of a single foundational theory. The purpose of this paper is precisely that: to present a description of gravity and electromagnetism as aspects of a single interaction. For that mat...

Not only is hydrogen (H2) the simplest and most abundant gas in our universe, it also plays a pivotal role in the decarbonization of our energy. As such hydrogen will be one of the most important critical enablers for industry in the global energy transition. Hydrogen’s low density hinders the wide-scale deployment and therefore, it is important to...

A quantum field has been coupled to a space-time with accelerating expansion. Dynamical modes are destabilised successively at shorter material wavelengths as they metamorphose from oscillators to repellers. Due to degeneracy of energy levels, the number of unstable modes increases at an accelerating rate, sufficient to account for a significant pr...

The Lorentz force law is fundamental for electromagnetism. However, it is known long ago that the Lorentz forces between two current elements do not respect the Newton's third law. This seemingly harmless flaw had never been corrected. In physical sciences a discrepancy often hides in it new understanding or unexpected breakthrough. For solving thi...
