Ann Arbor Central Fire Station
The Ann Arbor Hands-On Museum, located in Ann Arbor, Michigan, United States, specializes in interactive exhibits with the goal of helping both children and adults discover the scientist within them by promoting science literacy through experimentation, exploration, and education. History The Ann Arbor Hands-On Museum was founded in 1978, with approval from the city of Ann Arbor, as a touring collection of exhibits built by local specialists and volunteers. The museum opened at its permanent location in 1982 in the city's historic brick firehouse with 25 exhibits on two floors, one staff person, and ten volunteers. During the museum's first year of operation, it welcomed 25,000 guests. Children and adults both expressed great curiosity and enthusiasm, which pushed the museum to accelerate its expansion plans. Four years later, the museum opened the third and fourth floors of the firehouse with the help of a Kresge Foundation Challenge Grant. In 1993, the museum purchased several ...

Draughts
Checkers (American English), also known as draughts (; British English), is a group of strategy board games for two players which involve diagonal moves of uniform game pieces and mandatory captures by jumping over opponent pieces. Checkers is developed from alquerque. The term "checkers" derives from the checkered board which the game is played on, whereas "draughts" derives from the verb "to draw" or "to move". The most popular forms of checkers in Anglophone countries are American checkers (also called English draughts), which is played on an 8×8 checkerboard; Russian draughts, Turkish draughts both on an 8x8 board, and International draughts, played on a 10×10 board – the latter is widely played in many countries worldwide. There are many other variants played on 8×8 boards. Canadian checkers and Singaporean/Malaysian checkers (also locally known as ''dum'') are played on a 12×12 board. American checkers was weakly solved in 2007 by a team of Canadian computer s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victrola
The Victor Talking Machine Company was an American recording company and phonograph manufacturer that operated independently from 1901 until 1929, when it was acquired by the Radio Corporation of America and subsequently operated as a subsidiary called RCA Victor. Headquartered in Camden, New Jersey, it was the largest and most prestigious firm of its kind in the world, probably best known for its use of the iconic "His Master's Voice" trademark and the production, marketing, and design of the popular "Victrola" line of phonographs. After its merger with RCA in 1929, the company continued to make phonographs, records, radios and other products. History In 1896, Emile Berliner—inventor of the gramophone and disc record—contracted machinist Eldridge R. Johnson to manufacture his inventions.Gelatt, Roland, ''The Fabulous Phonograph: 1877–1977'', MacMillan, New York, 1954. Name There are different accounts as to how the "Victor" name came about.

Period (music)
In music, the term period refers to certain types of recurrence in small-scale formal structure. In twentieth-century music scholarship, the term is usually used as defined by the ''Oxford Companion to Music'': "a period consists of two phrases, antecedent and consequent, each of which begins with the same basic motif." Earlier usage varied somewhat, but usually referred to similar notions of symmetry, recurrence, and closure. The concept of a musical period originates in comparisons between music structure and rhetoric at least as early as the 16th century. Western art music In Western art music or Classical music, a period is a group of phrases consisting usually of at least one antecedent phrase and one consequent phrase totaling about 8 bars in length (though this varies depending on meter and tempo). Generally, the antecedent ends in a weaker and the consequent in a stronger cadence; often, the antecedent ends in a half cadence while the consequent ends in an authentic ...

Cash Register
A cash register, sometimes called a till or automated money handling system, is a mechanical or electronic device for registering and calculating transactions at a point of sale. It is usually attached to a drawer for storing cash and other valuables. A modern cash register is usually attached to a printer that can print out receipts for record-keeping purposes. History An early mechanical cash register was invented by James Ritty and John Birch following the American Civil War. James was the owner of a saloon in Dayton, Ohio, US, and wanted to stop employees from pilfering his profits. The Ritty Model I was invented in 1879 after seeing a tool that counted the revolutions of the propeller on a steamship. With the help of James' brother John Ritty, they patented it in 1883. It was called ''Ritty's Incorruptible Cashier'' and it was invented to stop cashiers from pilfering and eliminate employee theft and embezzlement. Early mechanical registers were entirely mechanical, wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climbing Wall
A climbing wall is an artificially constructed wall with grips for hands and feet, usually used for indoor climbing, but sometimes located outdoors. Some are brick or wooden constructions, but on most modern walls, the material most often used is a thick multiplex board with holes drilled into it. Recently, manufactured steel and aluminum have also been used. The wall may have places to attach belay ropes, but may also be used to practice lead climbing or bouldering. Each hole contains a specially formed t-nut to allow modular climbing holds to be screwed onto the wall. With manufactured steel or aluminum walls, an engineered industrial fastener is used to secure climbing holds. The face of the multiplex board climbing surface is covered with textured products including concrete and paint or polyurethane loaded with sand. In addition to the textured surface and hand holds, the wall may contain surface structures such as indentions (incuts) and protrusions (bulges), or take th ...

Magnet
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone. Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to ...

Traffic Light
Traffic lights, traffic signals, or stoplights – known also as robots in South Africa are signalling devices positioned at intersection (road), road intersections, pedestrian crossings, and other locations in order to control flows of traffic. Traffic lights consist normally of three signals, transmitting meaningful information to drivers and riders through colours and symbols including arrows and bicycles. The regular traffic light colours are red, yellow, and green arranged vertically or horizontally in that order. Although this is internationally standardised,1968, as revised 1995 and 2006Vienna Convention on Road Signs and Signals United Nations Publication ECE/TRANS/196. ISBN 978-92-1-116973-7. URL Accessed: 7 January 2022. variations exist on national and local scales as to traffic light sequences and laws. The method was first introduced in December 1868 on Parliament Square in London to reduce the need for police officers to control traffic. Since then, electricity ...

Fire Apparatus
A firefighting apparatus describes any vehicle that has been customized for use during firefighting operations. These vehicles are highly customized depending on their needs and the duty they will be performing. These duties can include firefighting and emergency medical services. History An early device used to squirt water onto a fire is a ''squirt'' or ''fire syringe''. Hand squirts and hand pumps are noted before Ctesibius of Alexandria invented the first fire pump circa the 2nd century B.C., and an example of a force-pump possibly used for a fire-engine is mentioned by Heron of Alexandria. The fire pump was reinvented in Europe during the 16th century, reportedly used in Augsburg in 1518 and Nuremberg in 1657. A book of 1655 inventions mentions a steam engine (called a ''fire engine'') pump used to "raise a column of water 40 feet []", but there was no mention of whether it was portable. Colonial laws in America required each house to have a bucket of water on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firefighter
A firefighter is a first responder and rescuer extensively trained in firefighting, primarily to extinguish hazardous fires that threaten life, property, and the environment as well as to rescue people and in some cases or jurisdictions also animals from dangerous situations. Male firefighters are sometimes referred to as firemen (and, less commonly, a female firefighter as firewoman). The fire service, also known in some countries as the fire brigade or fire department, is one of the three main emergency services. From urban areas to aboard ships, firefighters have become ubiquitous around the world. The skills required for safe operations are regularly practised during training evaluations throughout a firefighter's career. Initial firefighting skills are normally taught through local, regional or state-approved fire academies or training courses. Depending on the requirements of a department, additional skills and certifications such as technical rescue and pre-hospital ...
