Scientists solve 90-year-old geometry problem

Carnegie Mellon University computer scientists and mathematicians have resolved the last, stubborn piece of Keller's conjecture, a geometry problem that scientists have puzzled over for 90 years.

Whales used to identify Arabian horses

A computer program that mimics in software the social interactions of the humpback whale has been used by researchers in Egypt to build a system for the identification of Arabian horses.

Charting a course toward quantum simulations of nuclear physics

In nuclear physics, like much of science, detailed theories alone aren't always enough to unlock solid predictions. There are often too many pieces, interacting in complex ways, for researchers to follow the logic of a theory ...

Speak math, not code

Have you ever followed a recipe to bake some bread? If you have, congratulations; you have executed an algorithm. The algorithms that follow us around the internet to suggest items we might like, and those that control what ...

Opinion: Why all children must learn code

Across the world, the conversion of information into a digital format—also called "digitalization"—has increased productivity in the public and private sectors. As a result, virtually every country in the world is working ...

A 'simulation booster' for nanoelectronics

Two research groups from ETH Zurich have developed a method that can simulate nanoelectronics devices and their properties realistically, quickly and efficiently. This offers a ray of hope for the industry and data center ...

Computer program

Computer programs (also software programs, or just programs) are instructions for a computer. A computer requires programs to function, typically executing the program's instructions in a central processor. The program has an executable form that the computer can use directly to execute the instructions. The same program in its human-readable source code form, from which executable programs are derived (e.g., compiled), enables a programmer to study and develop the algorithm.

Computer source code is often written by professional computer programmers. Source code is written in a programming language that usually follows one of two main paradigms: imperative or declarative programming. Source code may be converted into an executable file (sometimes called an executable program or a binary) by a compiler. Alternatively, computer programs may be executed by a central processing unit with the aid of an interpreter, or may be embedded directly into hardware (in which case it is more widely known under the term 'firmware', as something 'between' software and hardware).

Computer programs may be categorized along functional lines: system software and application software. And many computer programs may run simultaneously on a single computer, a process known as multitasking.
