IN BRIEF Electromagnetism: study of interactions between charged particles. Electromagnetic field: combination of electric and magnetic fields. An electric field is associated with a voltage. A magnetic field arises from moving electric charges. Both fields are inseparable and interact with each other. An electric current generates both an electric field and a magnetic field. The … Read more
IN BRIEF Basic concepts in physics adapted for children Understanding fundamental forces Exploration of linear and rotational motion Conservation of energy laws Introduction to electricity and electromagnetism Simple explanations for atoms and molecules Quizzes to test knowledge Visual aids to enhance understanding Physics is a fascinating science that seeks to understand the rules that govern … Read more
IN BRIEF Symmetry: Fundamental concept in physics, reflecting the invariance of a system under transformations. Transformations: Symmetries can be associated with changes such as rotations or inversions. Symmetry groups: Mathematical structure that formalizes the relationships between symmetries and physical laws. Conservation: Each symmetry leads to the conservation of a physical quantity, according to Noether’s theorem. … Read more
IN BRIEF Big Bang: cosmic event marking the origin of the Universe according to the current cosmological model. Origins of the Universe: study of the conditions preceding and following the Big Bang. Formation Eras: the Universe evolved through the radiation era, followed by the matter era. String Theory: suggests that the Big Bang could be … Read more
IN BRIEF Definition: Quantum physics is a set of theories developed in the 20th century to explain the behavior of atoms and particles. Scientific revolution: Considered one of the two great revolutions of the twentieth century, alongside the theory of relativity. Nature of interactions: It describes how energy is exchanged in discrete values called quanta. … Read more
IN BRIEF 1803 : John Dalton proposes a first atomic model. 1897 : Discovery of the electron by Thomson. 1911 : Identification of the nucleus by Rutherford. 1920 : Discovery of the proton. 1922 : Development of the electron shells by Bohr. Transition from Dalton to Bohr models, integrating energy levels. The Bohr model remains … Read more
IN BRIEF The theory of relativity formulated by Albert Einstein. Special relativity discovered in 1905, challenging classical notions. General relativity established in 1915, revising our understanding of gravity. Time can slow down and space can contract. This theory has revolutionized our view of the universe. Essential implications in physics and astrophysics. Initial criticisms but only … Read more
IN BRIEF Conservation of energy principle: The total energy of an isolated system does not change. Energy transformation: Energy can be transformed or transferred, but never created or destroyed. Mechanical energy: The sum of kinetic and potential energy remains constant in an isolated system. First principle of thermodynamics: The total energy is conserved in any … Read more
IN BRIEF Elementary particles: fundamental units of matter. Quarks: components of protons and neutrons, grouped into hadrons. Leptons: particles such as electrons, without color charge. Standard model: theoretical framework encompassing particles and their interactions. Bosons: mediators of fundamental forces (e.g., the Higgs boson). Classification of particles into fermions (quarks and leptons) and bosons. Particle interaction: … Read more
