In theoretical physics, quantum field theory in curved spacetime (QFTCS) is an extension of quantum field theory from Minkowski spacetime to a general curved spacetime. This theory treats spacetime as a fixed, classical background, while giving a quantum-mechanical description of the matter and energy propagating through that spacetime. A general prediction of this theory is […]

In quantum field theory, a fermionic field is a quantum field whose quanta are fermions; that is, they obey Fermi–Dirac statistics. Fermionic fields obey canonical anticommutation relations rather than the canonical commutation relations of bosonic fields. The most prominent example of a fermionic field is the Dirac field, which describes fermions with spin-1/2: electrons, protons,
The National Assessment of Educational Progress (NAEP) is the largest continuing and nationally representative assessment of what U.S. students know and can do in various subjects. NAEP is a congressionally mandated project administered by the National Center for Education Statistics (NCES), within the Institute of Education Sciences (IES) of the U.S. Department of Education. The

Apollo 16 was the tenth crewed mission of NASA’s Apollo program and the fifth mission to land humans on the Moon. Launched on April 16, 1972, it marked the first lunar landing in the lunar highlands, an area of great geological interest. The mission provided valuable insights into the Moon’s early history and tested scientific
Kadimakara australiensis is an extinct species of marine reptile belonging to the clade Ichthyosauria, a group of dolphin-shaped reptiles that inhabited the world’s oceans during the Mesozoic Era. The species is known from fossil material discovered in South Australia and dates to the Early Jurassic period, approximately 190–180 million years ago. Originally assigned to the

Sonar (Sound Navigation and Ranging) is a technology used to detect objects underwater and measure distances using sound waves. It is widely used in navigation, submarine detection, fishing, and oceanography. 🐟🚢 Sonar works by sending sound pulses into the water and listening for echoes that bounce back from objects. The time it takes for the

Speciation is the evolutionary process by which populations of organisms diverge into distinct species. It is a central concept in evolutionary biology, explaining the diversity of life on Earth. Speciation occurs when genetic differences accumulate within populations, eventually leading to reproductive isolation—meaning members of one group can no longer interbreed successfully with members of another.
Overview DNA damage refers to structural alterations in the molecular architecture of deoxyribonucleic acid (DNA) that disrupt its normal chemical configuration. DNA encodes the genetic instructions necessary for cellular function, replication, and inheritance. When its structure is modified by physical, chemical, or biological agents, the integrity of genetic information is threatened. DNA damage occurs continuously
👥 Sociology Sociology is the scientific study of social life, social change, and the social causes and consequences of human behavior. It examines how people interact within groups, organizations, and societies, and how those social structures shape individual lives. 🌍 As of 2026, the field is increasingly focused on the “Sociology of the Future,” investigating
A pupa is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect’s hormones, especially juvenile hormone, prothoracicotropic
