Heat conduction, also known as thermal conduction, is the process by which heat energy is transferred through a material without the movement of the material itself. This fundamental principle of physics describes how heat moves from a region of higher temperature to a region of lower temperature within a solid,…

Heat radiation, also known as thermal radiation or infrared radiation, is a fundamental form of electromagnetic radiation emitted by objects due to their temperature. Unlike conduction and convection, which require a medium (such as air or water) to transfer heat, radiation can propagate through a vacuum. This makes heat radiation…

Heat and temperature are fundamental concepts in physics that describe the behavior of thermal energy and its effects on matter. Temperature is a measure of the average kinetic energy of particles within a substance or system. It indicates how hot or cold an object or environment is relative to a…

Heat transfer is the process by which thermal energy moves from one object or substance to another due to a difference in temperature. It is a fundamental concept in physics and engineering, essential for understanding various natural phenomena and technological applications. Heat transfer occurs through three primary mechanisms: conduction, convection,…

Heat is a fundamental form of energy associated with the motion of molecules within a substance. It is defined as the transfer of thermal energy between substances due to a temperature difference. Heat flows spontaneously from regions of higher temperature to regions of lower temperature until thermal equilibrium is achieved….

Harriet Brooks (1876–1933) was a pioneering Canadian physicist who made significant contributions to the field of nuclear physics, particularly in the study of radioactivity. Born on July 2, 1876, in Exeter, Ontario, Brooks displayed an early aptitude for science and mathematics, which led her to pursue higher education in a…

Harmonic motion, also known as simple harmonic motion (SHM), is a fundamental concept in physics that describes the repetitive back-and-forth motion of an object around a stable equilibrium position. This type of motion occurs when a restoring force, such as gravity or a spring force, is proportional to the displacement…

Ionizing radiation encompasses a spectrum of high-energy particles or electromagnetic waves that have enough energy to liberate electrons from atoms, creating ions in their wake. This form of radiation is categorized into alpha particles, beta particles, gamma rays, X-rays, and neutrons, each with distinct properties and abilities to penetrate matter….

Inertia, a fundamental concept in physics, refers to the tendency of an object to resist changes in its state of motion. This property, described by Newton’s First Law of Motion, asserts that an object at rest will remain at rest, and an object in motion will continue moving at a…

Ingrid Daubechies, born on August 17, 1954, in Houthalen, Belgium, is a distinguished physicist and mathematician known for her profound contributions to wavelet theory. Her academic journey led her to earn a Ph.D. in theoretical physics from Vrije Universiteit Brussel in 1980. Daubechies is particularly celebrated for her pioneering work…
