The term engineering is derived from the Latiningenium, meaning "cleverness". (Full article...)
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. The word engineer (Latiningeniator, the origin of the Ir. in the title of engineer in countries like Belgium and The Netherlands) is derived from the Latin words ingeniare ("to contrive, devise") and ingenium ("cleverness"). The foundational qualifications of a licensed professional engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professional practice (culminating in a project report or thesis) and passage of engineering board examinations.

After several modifications, the first production variants of the PV-12 were completed in 1936. The first operational aircraft to enter service using the Merlin were the Fairey Battle, Hawker Hurricane and Supermarine Spitfire. More Merlins were made for the four-engined Avro Lancaster heavy bomber than for any other aircraft; however, the engine is most closely associated with the Spitfire, starting with the Spitfire's maiden flight in 1936. A series of rapidly applied developments, brought about by wartime needs, markedly improved the engine's performance and durability. (Full article...)
A turbine is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator or producing thrust, as in the case of jet engines. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels.
A chicken gun or flight impact simulator is a large-diameter, compressed-air gun used to fire bird carcasses at aircraft components in order to simulate high-speed bird strikes during the aircraft's flight. Jet engines and aircraft windshields are particularly vulnerable to damage from such strikes, and are the most common target in such tests. Although various species of bird are used in aircraft testing and certification, the device acquired the common name of "chicken gun" as chickens are the most commonly used 'ammunition' owing to their ready availability.

The radius of maximum wind of a tropical cyclone lies just within the eyewall of an intense tropical cyclone, such as Hurricane Isabel from 2003 The radius of maximum wind (RMW) is the distance between the center of a cyclone and its band of strongest winds. It is a parameter in atmospheric dynamics and tropical cyclone forecasting. The highest rainfall rates occur near the RMW of tropical cyclones. The extent of a cyclone's storm surge and its maximum potential intensity can be determined using the RMW. As maximum sustained winds increase, the RMW decreases. Recently, RMW has been used in descriptions of tornadoes. When designing buildings to prevent against failure from atmospheric pressure change, RMW can be used in the calculations. (Full article...)
Meticulous naval inventories show that HMS Beagle carried a total of at least 34 recorded chronometers on its three main survey voyages from 1826 to 1843, and 22 on the second voyage with Darwin on board, when they had a dedicated cabin. Some were Navy property and others were on loan from the manufacturers, as well as six on the second voyage owned by the captain, Robert FitzRoy. Both the two known survivors from the second voyage are owned by the British Museum (the second is registration No. CAI.1743). (Full article...)
The Churchill Machine Tool Company Limited began as the manufacturing subsidiary of the machine tool importers Charles Churchill & Company Limited founded in the early 1900s by US-born Charles Churchill (1837–1916). Created out of the personal bankruptcy of Charles Churchill, the company developed to become one of the largest British importers of machine tools from the United States and a major manufacturer of such tools, initially under licence and later of its own development.
The original business importing American machine tools into Britain began with Charles Churchill as sole proprietor and later as a partnership with two others. It became a limited company in 1889. In 1906 a separate company, The Churchill Machine Tool Co Ltd, was established with the purpose of adapting tools imported by Charles Churchill & Co. The former expanded, producing American tools under licence and then manufactured tools of its own design, in particular precision surface grinders and similar engineering machinery. In 1918 The Churchill Machine Tool Co relocated its factories onto a single site at Broadheath, near Altrincham. (Full article...)
Overhead View of Tehachapi Energy Storage Project, Tehachapi, CA
The Tehachapi Energy Storage Project (TSP) is a 8MW/32MWhlithium-ion battery-based grid energy storage system at the Monolith Substation of Southern California Edison (SCE) in Tehachapi, California, sufficient to power between 1,600 and 2,400 homes for four hours. At the time of commissioning in 2014, it was the largest lithium-ion battery system operating in North America and one of the largest in the world. TSP is considered to be a modern-day energy storage pioneer with significant accomplishments that have proven the viability of utility-scale energy storage using lithium-ion technology. While originally envisioned as a research and development project, TSP operated as a distribution-level resource for SCE and for calendar year 2020, SCE reported that TSP operated in the wholesale energy market with revenue exceeding operating and maintenance costs. In 2021, SCE began the decommissioning of TSP, which was followed by formal decommissioning by state regulators in 2022. The physical dismantlement of TSP is expected to be completed by the end of 2022. (Full article...)

A voltage doubler is an electronic circuit which charges capacitors from the input voltage and switches these charges in such a way that, in the ideal case, exactly twice the voltage is produced at the output as at its input.
The simplest of these circuits is a form of rectifier which take an AC voltage as input and outputs a doubled DC voltage. The switching elements are simple diodes and they are driven to switch state merely by the alternating voltage of the input. DC-to-DC voltage doublers cannot switch in this way and require a driving circuit to control the switching. They frequently also require a switching element that can be controlled directly, such as a transistor, rather than relying on the voltage across the switch as in the simple AC-to-DC case.

Raymix during a 2018 interview
Edmundo Gómez Moreno (born 17 February 1991), better known by his stage name Raymix, is a Mexican musician and aerospace engineer. Nicknamed El Rey de la Electrocumbia ("The King of Electrocumbia"), Raymix started his music career in the early 2010s, when he joined a trance project called Light & Wave with two other Mexican musicians. Their song "Feeling the City" was featured on the Armin van Buuren radio show A State of Trance. In 2013, Raymix was invited to work in a NASA educative internship, where he helped to develop a satellite.
The tubes were constructed using the shield method and are each 6,550 feet (2,000 m) long and 15.5 feet (4.7 m) wide. The interiors are lined with cast-iron "rings" formed with concrete. The tubes descend 91 to 95 feet (28 to 29 m) below the mean high water level of the East River, with a maximum gradient of 3.1 percent. During the tunnel's construction, a house at 58 Joralemon Street in Brooklyn was converted into a ventilation building and emergency exit. (Full article...)

Pavel Lvovitch Schilling. Portrait by Karl Bryullov, 1828
Baron Pavel Lvovitch Schilling (1786–1837), also known as Paul Schilling, was a Russian inventor, military officer and diplomat of Baltic German origin. The majority of his career was spent working for the imperial Russian Ministry of Foreign Affairs as a language officer at the Russian embassy in Munich. As a military officer, he took part in the War of the Sixth Coalition against Napoleon. In his later career, he was transferred to the Asian department of the ministry and undertook a tour of Mongolia to collect ancient manuscripts.
Bell was an energetic and skilful entrepreneur as well as an innovative metallurgist. He was involved in multiple partnerships with his brothers to make iron and alkali chemicals, and with other pioneers including Robert Stirling Newall to make steel cables. He pioneered the large-scale manufacture of aluminium at his Washington works, conducting experiments in its production, and in the production of other chemicals such as the newly discovered element thallium. He was a director of major companies including the North Eastern Railway and the Forth Bridge company, then the largest bridge project in the world. (Full article...)
Image 12Design of a turbine requires collaboration of engineers from many fields, as the system involves mechanical, electro-magnetic and chemical processes. The blades, rotor and stator as well as the steam cycle all need to be carefully designed and optimized. (from Engineering)
Image 16The application of the steam engine allowed coke to be substituted for charcoal in iron making, lowering the cost of iron, which provided engineers with a new material for building bridges. This bridge was made of cast iron, which was soon displaced by less brittle wrought iron as a structural material. (from Engineering)
