Geant4 (for GEometry ANd Tracking) is a platform for "the simulation of the passage of particles through matter" using Monte Carlo methods. It is the successor of the GEANT series of software toolkits developed by The Geant4 Collaboration, and the first to use object oriented programming (in C++ ).
Single-particle tracking ( SPT) is the observation of the motion of individual particles within a medium. The coordinates time series, which can be either in two dimensions ( x, y) or in three dimensions ( x, y, z ), is referred to as a trajectory. The trajectory is typically analyzed using statistical methods to extract information about the ...
Open Source Physics, or OSP, is a project sponsored by the National Science Foundation and Davidson College, whose mission is to spread the use of open source code libraries that take care of a lot of the heavy lifting for physics: drawing and plotting, differential equation solvers, exporting to animated GIFs and movies, etc., tools, and compiled simulations for physics and other numerical ...
Tracking (particle physics) In particle physics, tracking is the process of reconstructing the trajectory (or track) of electrically charged particles in a particle detector known as a tracker. The particles entering such a tracker leave a precise record of their passage through the device, by interaction with suitably constructed components ...
In physics, quintessence is a hypothetical form of dark energy, more precisely a scalar field, postulated as an explanation of the observation of an accelerating rate of expansion of the universe. The first example of this scenario was proposed by Ratra and Peebles (1988) [1] and Wetterich (1988). [2] [3] The concept was expanded to more ...
A tractor beam is a device that can attract one object to another from a distance. [1] The concept originates in fiction: The term was coined by E. E. Smith (an update of his earlier "attractor beam") in his novel Spacehounds of IPC (1931). Since the 1990s, technology and research have labored to make it a reality, and have had some success on ...
Pure physics is a branch of fundamental science (also called basic science). Physics is also called " the fundamental science" because all branches of natural science like chemistry, astronomy, geology, and biology are constrained by laws of physics. [60] Similarly, chemistry is often called the central science because of its role in linking ...
ATLAS detector under construction in October 2004 in the experiment pit. Construction was completed in 2008 and ATLAS has been successfully collecting data since November 2009, when colliding beam operation at the LHC started. Note the people in the background, for size comparison. The first cyclotron, an early type of particle accelerator, was ...
