File deletion is the removal of a file from a computer's file system. All operating systems include commands for deleting files (rm on Unix and Linux, [1] era in CP/M and DR-DOS, del/erase in MS-DOS/PC DOS, DR-DOS, Microsoft Windows etc.). File managers also provide a convenient way of deleting files. Files may be deleted one-by-one, or a whole ...
Watching out for pseudoscience in physics articles and categories (see the list of these topics). Keeping the Physics Portal in good shape. Keeping the WikiProject Physics community active, growing, and well-supported. Discussing the content of physics articles on Wikipedia and what direction WikiProject Physics should take (see talk page).
Forces can be either placed directly by the user or produced by adding gravitation, Coulomb force or other effects. The program also features springs and soft bodies . Step allows reverting after simulation, so the user can modify the bodies and forces and see how the outcome of the simulation is affected.
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 ...
Physics Forums is a question and answer Internet forum that allows users to ask, answer and comment on grade-school through graduate-level science questions. In addition, Physics Forums hosts the Insights Blog which is a collaborative blog sourced from verified experts on the community.
Quantum chemistry computer programs are used in computational chemistry to implement the methods of quantum chemistry. Most include the Hartree–Fock (HF) and some post-Hartree–Fock methods. They may also include density functional theory (DFT), molecular mechanics or semi-empirical quantum chemistry methods .
VPython is Open Source, and a part of the Python Library, combining the Python programming language with a 3D graphics module called Visual.. This library application allows users to create 3D objects, such as spheres and cones, and then display these objects in an app window.
The most basic operations that programs can perform on a file are: Create a new file; Change the access permissions and attributes of a file; Open a file, which makes the file contents available to the program; Read data from a file; Write data to a file; Delete a file; Close a file, terminating the association between it and the program
