A virtual field trip is a guided exploration through the World Wide Web that organizes a collection of pre-screened, thematically based web pages into a structured online learning experience. (Foley, 2003). Since 2007, another dynamic and interactive form of a virtual field trip has been – and is – freely available.
Virtual photons are a fundamental concept in particle physics and quantum field theory that play a crucial role in describing the interactions between electrically charged particles. Virtual photons are referred to as "virtual" because they do not exist as free particles in the traditional sense but instead serve as intermediate particles in ...
A virtual particle is a theoretical transient particle that exhibits some of the characteristics of an ordinary particle, while having its existence limited by the uncertainty principle, which allows the virtual particles to spontaneously emerge from vacuum at short time and space ranges.
Virtual reality in primary education. Virtual reality (VR) is a computer application which allows users to experience immersive, three dimensional visual and audio simulations. According to Pinho (2004), virtual reality is characterized by immersion in the 3D world, interaction with virtual objects, and involvement in exploring the virtual ...
Virtual-particle exchange. In perturbation theory, forces are generated by the exchange of virtual particles. The mechanics of virtual-particle exchange is best described with the path integral formulation of quantum mechanics.
Virtual reality (VR) is a part of technology that allows the user to explore computer generated, real or artificial three-dimensional multimedia sensory environments in real time to gain practical knowledge that can be used in clinical practice. [11]
Virtual reality (VR) is a simulated experience that employs 3D near-eye displays and pose tracking to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games ), education (such as medical, safety or military training) and business (such as virtual meetings).
t. e. In quantum field theory, the Casimir effect (or Casimir force) [1] is a physical force acting on the macroscopic boundaries of a confined space which arises from the quantum fluctuations of a field. It is named after the Dutch physicist Hendrik Casimir, who predicted the effect for electromagnetic systems in 1948.
Digital learning is learning that is supported by technology. It encompasses any type of learning that is accompanied by technology or by instructional practice that makes effective use of technology. It includes a wide array of practices, including blended and virtual learning. A variety of names began to be used to denote education conducted ...
The quantization of the electromagnetic field means that an electromagnetic field consists of discrete energy parcels called photons. Photons are massless particles of definite energy , definite momentum , and definite spin .
