A steam turbine with the case opened. Such turbines produce most of the electricity used today. Electricity consumption and living standards are highly correlated. Electrification is believed to be the most important engineering achievement of the 20th century.

Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is the sum of techniques, skills, methods, and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, and the like, or it can be embedded in machines to allow for operation without detailed knowledge of their workings. Systems (e.g. machines) applying technology by taking an input, changing it according to the system's use, and then producing an outcome are referred to as technology systems or technological systems.

The simplest form of technology is the development and use of basic tools. The prehistoric discovery of how to control fire and the later Neolithic Revolution increased the available sources of food, and the invention of the wheel helped humans to travel in and control their environment. Developments in historic times, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale.

Parallel computing is a type of computation in which many calculations or the execution of processes are carried out simultaneously. Large problems can often be divided into smaller ones, which can then be solved at the same time. There are several different forms of parallel computing: bit-level, instruction-level, data, and task parallelism. Parallelism has long been employed in high-performance computing, but it's gaining broader interest due to the physical constraints preventing frequency scaling. As power consumption (and consequently heat generation) by computers has become a concern in recent years, parallel computing has become the dominant paradigm in computer architecture, mainly in the form of multi-core processors.

Featured biography

Benjamin Mountfort around 1875
Benjamin Woolfield Mountfort (13 March 1825 – 15 March 1898) was an English emigrant to New Zealand, where he became one of that country's most prominent 19th-century architects. He was instrumental in shaping the city of Christchurch's unique architectural identity and culture, and was appointed the first official Provincial Architect of the developing province of Canterbury. Heavily influenced by the Anglo-Catholic philosophy behind early Victorian architecture, he is credited with importing the Gothic revival style to New Zealand. His Gothic designs constructed in both wood and stone in the province are considered unique to New Zealand. Today, he is considered the founding architect of the province of Canterbury. Read more...

While educational facilities close across the United States due to the coronavirus pandemic, the U.S. Department of Education tells educators that online learning must comply with civil rights laws, including making sure learning tools are available to students. However, as not every student has access to the internet, many students will be unable to participate, prompting some public school systems to implement "enrichment" policies. Under these policies, coursework completed under online learning will not officially count towards advancing to the next academic term. (The Wall Street Journal)
