Porter Chemical Company
Porter Chemical Company was an American toy manufacturer that developed and produced chemistry sets aimed as educational toys for aspiring junior scientists. The company's ''Chemcraft'' kits were first sold at major retail by Woodward & Lothrop, and appeared soon after at other retailers in the country. The company would later form a relationship with the Lionel Corporation, famed American maker of toy trains. The company also made the ''Microcraft'' line of microscope sets. The ''Chemcraft'' and ''Microcraft'' line competed with similar sets offered by A. C. Gilbert Company as part of a boom in science educational toys spurred by the Space Race The Space Race was a 20th-century competition between two Cold War rivals, the United States and the Soviet Union, to achieve superior spaceflight capability.

Hagerstown, Maryland
Hagerstown is a city in Washington County, Maryland, United States and the county seat of Washington County.

These ridges consist of upper Stonehenge limestone. Many of the older buildings were built from this stone, which is easily quarried and dressed onsite. It whitens in weathering and the edgewise conglomerate and wavy laminae become distinctly visible, giving a handsome and uniquely "Cumberland Valley" appearance. Several of Hagerstown's churches are constructed of Stonehenge limestone. Its value and beauty as building rock may ...

Chemistry Set
A chemistry set is an educational toy allowing the user (typically a teenager) to perform simple chemistry experiments. History Forerunners The forerunners of the chemistry set were 17th century books on "natural magick", "which all excellent wise men do admit and embrace, and worship with great applause; neither is there any thing more highly esteemed, or better thought of, by men of learning." Authors such as Giambattista della Porta included chemical magic tricks and scientific puzzles along with more serious topics. The earliest chemistry sets were developed in the 18th century in England and Germany to teach chemistry to adults. In 1791, ''Description of a portable chest of chemistry : or, Complete collection of chemical tests for the use of chemists, physicians, mineralogists, metallurgists, scientific artists, manufacturers, farmers, and the cultivators of natural philosophy'' by Johann Friedrich August Göttling, translated from German, was published in English. ...

Woodward & Lothrop
Woodward & Lothrop was a department store chain headquartered in Washington, D.C. that began as the capital's first department store in 1887. Woodies, as it was often nicknamed, maintained stores in the Mid-Atlantic United States. Its flagship store was a fixture of Washington, D.C.'s downtown shopping district, competing with Garfinckel's and acquiring Palais Royal. The chain filed for bankruptcy in January 1994 and completed liquidation in November 1995, with most locations sold to either J. C. Penney or May Department Stores Company. The flagship building is a D.C. historic landmark that would become the center of controversy over competing visions for DC's urban renewal after the chain's demise, and the former service warehouse in the city's northeast is also listed as a landmark. History Samuel Walter Woodward (1848 – August 2, 1917) and Alvin Mason Lothrop (1847–1912) opened a dry goods store in Chelsea, Massachusetts, in 1873, and maintained several stores in t ...

Toy Trains
A toy or plaything is an object that is used primarily to provide entertainment. Simple examples include toy blocks, board games, and dolls. Toys are often designed for use by children, although many are designed specifically for adults and pets. Toys can provide utilitarian benefits, including physical exercise, cultural awareness, or academic education. Additionally, utilitarian objects, especially those which are no longer needed for their original purpose, can be used as toys. Examples include children building a fort with empty cereal boxes and tissue paper spools, or a toddler playing with a broken TV remote control. The term "toy" can also be used to refer to utilitarian objects purchased for enjoyment rather than need, or for expensive necessities for which a large fraction of the cost represents its ability to provide enjoyment to the owner, such as luxury cars, high-end motorcycles, gaming computers, and flagship smartphones. Playing with toys can be an enjoyable way o ...

Space Race
The Space Race was a 20th-century competition between two Cold War rivals, the United States and the Soviet Union, to achieve superior spaceflight capability. It had its origins in the ballistic missile-based nuclear arms race between the two nations following World War II. The technological advantage demonstrated by spaceflight achievement was seen as necessary for national security, and became part of the symbolism and ideology of the time. The Space Race brought pioneering launches of artificial satellites, robotic space probes to the Moon, Venus, and Mars, and human spaceflight in low Earth orbit and ultimately to the Moon. Public interest in space travel originated in the 1951 publication of a Soviet youth magazine and was promptly picked up by US magazines. The competition began on July 30, 1955 when the United States announced its intent to launch artificial satellites for the International Geophysical Year. Four days later, the Soviet Union responded by declaring ...

''Wired'' (stylized as ''WIRED'') is a monthly American magazine, published in print and online editions, that focuses on how emerging technologies affect culture, the economy, and politics. Owned by Condé Nast, it is headquartered in San Francisco, California, and has been in publication since March/April 1993. Several spin-offs have been launched, including '' Wired UK'', ''Wired Italia'', ''Wired Japan'', and ''Wired Germany''. From its beginning, the strongest influence on the magazine's editorial outlook came from founding editor and publisher Louis Rossetto. With founding creative director John Plunkett, Rossetto in 1991 assembled a 12-page prototype, nearly all of whose ideas were realized in the magazine's first several issues. In its earliest colophons, ''Wired'' credited Canadian media theorist Marshall McLuhan as its "patron saint". ''Wired'' went on to chronicle the evolution of digital technology and its impact on society. ''Wired'' quickly became recognized ...
