Cherenkov radiation is an electromagnetic radiation phenomenon discovered in 1934 by Soviet physicist Pavel Cherenkov. This effect occurs when a charged particle moves through a medium faster than the speed of light in that medium. Einstein’s special theory of relativity states that the absolute speed limit in the universe is the speed of light in vacuum (c ≈ 3×10⁸ m/s). However, light propagates more slowly in transparent media such as water or glass. The speed of light in a medium is expressed

What you call motivation is simply convincing yourself anew each day.Motivation is not often about waking up with a powerful desire, as we tend to imagine.Sometimes you do not want to get out of bed when the alarm rings; sometimes you sigh inwardly, “Not again today?”… And yet you still step into the day.On social media, motivation is always portrayed as something grand: early risers, disciplined lives, people who never get tired… But real life rarely works that way. In reality, motivation can s

The invention of the battery is a pivotal moment in the shaping of the world. Today, the operation of many devices—from smartphones to electric vehicles—relies on battery technology that enables portable energy storage. However, the origins of this invention trace back to the pioneering experiments conducted by humans in the 18th century.

EnOriginEnergy entered Turkish from the French word énergie. The French term derives from the Ancient Greek enérgeia (ἐνέργεια), meaning “activity, action”. This Greek word is derived from energós (ἐνεργός), meaning “active, working”, which in turn traces its origin to érgon (ἔργον), meaning “work, labor, effort”. Structurally, it developed from the conceptual domain of “the power and activity of doing work”.Areas of UsePhysics and Natural Sciences: Refers to the capacity to perform work and the p

Renewable energy is the field of energy that aims to produce energy services such as heat, electricity, and fuel by harnessing flows that are continuously replenished through natural processes and can regenerate at a human scale. Sources such as solar radiation, wind, geothermal heat, the water cycle, and biomass are considered renewable due to their continuity in nature. The growth of this field is evaluated alongside objectives such as reducing the environmental impacts of fossil fuel-based pr

Psychic energy is defined as a fundamental power that directs an individual’s mental, emotional, and behavioral processes. In psychoanalytic theory, this energy is distributed in some way between conscious and unconscious processes and plays a critical role in the individual’s psychological functioning.Sigmund Freud viewed psychic energy as the primary source of human behavior and argued that it is especially guided by instincts. According to him, the amount of psychic energy an individual posse

Impact test is a standardized mechanical testing method used in engineering to measure the mechanical behavior of materials under dynamic and sudden loading. Unlike static loading, impact tests apply sudden high-velocity loads to the material, thereby determining whether the material exhibits ductile or brittle behavior under rapid and high-speed loading. The value representing the material’s resistance to such loads is referred to as impact resistance or impact energy. The importance of these t

Positronium (Ps) is an exotic atom consisting of an electron (e⁻) bound to its antiparticle, the the positron's (e⁺), by the Coulomb force. It has a structure similar to the hydrogen atom but contains a positron instead of a proton. This composition makes Ps a unique model for studying particle-antiparticle systems.The existence of positronium was first predicted theoretically by Mohorovičić in 1934. Its spectroscopic structure was calculated by Ruark in 1945, and its binding energy and lifetime

Carbon is a chemical element with atomic number 6, located in group 14 of the periodic table and represented by the symbol C. It is one of the most abundant elements in nature and forms the fundamental building block of all living organisms. Carbon atoms, with their four valence electrons, readily form bonds with many different atoms, enabling the creation of a vast array of complex molecules.Chemical and Physical PropertiesUnder standard conditions, carbon exists in solid form. It has a high ca
