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 lifetim

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. The image was generated by artificial intelligence.

Origin Energy 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 Use Physics and Natural Sciences: Refers to the capacity to perform work and th

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

High Technology, or its English equivalent High-Tech, architecture is an architectural movement that emerged in the second half of the 20th century as a reaction against modernist architectural principles, using technology as an aesthetic and structural expressive tool. Beginning in the 1960s, this approach emphasized industrial revolution-era building materials such as steel, glass, and concrete while aiming to reveal their functional, structural, and visual potential. The foundation of High-Te

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 ca

Power power electronics is an engineering discipline concerned with the control, conversion, and regulation of electricity electrical energy. This field focuses on semiconductor devices, circuit design, control systems, and energy transformation applications on. Power electronics enables the control of high-power electrical signals using low-power control signals to: Convert electrical energy (for example, from AC to DC or vice versa), Control electrical energy (for example, motor speed control)

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 Properties Under standard conditions, carbon exists in solid form. It has a high
