Albert Tissandier
Albert Tissandier (1839 – 5 September 1906) was a French architect, aviator, illustrator, editing, editor and archaeologist. He was the brother of adventurer Gaston Tissandier with whom he collaborated in writing the magazine ''La Nature'', a French language scientific journal aimed at the popular science, popularization of science. He and his brother demonstrated the first electric powered flight. Early years and ''La Nature'' Born in Paris in 1839, Albert Tissandier was a loyal and assiduous companion of his brother, Gaston Tissandier. As an architect, he was involved in a large number of projects. Though his brother was nominally the sole founder of ''La Nature'', a scientific journal aimed at the popularization of science, Albert contributed extensively to the magazine, mostly as an illustrator and editor. He was heavily involved in it from the very first issue in 1873 until his retirement in 1905, less than a year before his death. Aviation career His devotion to aer ...

Blueprints
A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets. Introduced by Sir John Herschel in 1842, the process allowed rapid and accurate production of an unlimited number of copies. It was widely used for over a century for the reproduction of specification drawings used in construction and industry. The blueprint process was characterized by white lines on a blue background, a negative of the original. The process was not able to reproduce color or shades of grey. The process is now obsolete. It was first largely displaced by the diazo whiteprint process, and later by large-format xerographic photocopiers. The term ''blueprint'' continues to be used less formally to refer to any floor plan (and even less formally, any type of plan). Practicing engineers, architects, and drafters often call them "drawings", “prints”, or “plans”. It has almost entirely been replaced with digital computer-aided ...

Dirigible
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air.A few airships after World War II used hydrogen. The first British airship to use helium was the ''Chitty Bang Bang'' of 1967. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has engines, crew, and optionally also payload accommodation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Motor
An electric motor is an Electric machine, electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a Electromagnetic coil, wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy. Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, Inverter (electrical), inverters or electrical generators. Electric motors may be classified by considerations such as power source type, construction, application and type of motion output. They can be powered by AC or DC, be Brushed motor, brushed or Brushless motor, brushless, single-phase, Two-phase electric power, two-p ...

Deaf
Deafness has varying definitions in cultural and medical contexts. In medical contexts, the meaning of deafness is hearing loss that precludes a person from understanding spoken language, an Audiology, audiological condition. In this context it is written with a lower case ''d''. It later came to be used in a cultural context to refer to those who primarily communicate through sign language regardless of hearing ability, often capitalized as ''Deaf'' and referred to as "big D Deaf" in speech and sign. The two definitions overlap but are not identical, as hearing loss includes cases that are not severe enough to impact spoken language comprehension, while cultural Deafness includes hearing people who use sign language, such as Child of deaf adult, children of deaf adults. Medical context In a medical context, deafness is defined as a degree of hearing difference such that a person is unable to understand speech, even in the presence of amplification. In profound deafness, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Joseph Croce-Spinelli
Joseph is a common male given name, derived from the Hebrew Yosef (יוֹסֵף). "Joseph" is used, along with "Josef", mostly in English, French and partially German languages.

In Arabic, including in the Quran, the name is spelled ''Yūsuf''. In Persian, the name is "Yousef". The name has enjoyed significant popularity in its many forms in numerous countries, and ''Joseph'' was one of the two names, along with ''Robert'', to have remained in the top 10 boys' names list in the US from 1925 to 1972. It is especially common in contemporary Israel, as either "Yossi" or "Yossef", and in Italy, where the name "Giuseppe" was the most common male name in the 20th century. In the first century CE, Joseph was the second most popular male name for Palestine Jews. In the Book of Genesis Joseph is Jacob's eleventh son and Rachel's first son, and kn ...

Arcachon
Arcachon ( ; ) is a commune in the southwestern French department of Gironde. It is a popular seaside resort on the Atlantic coast southwest of Bordeaux, in the Landes forest. It has a sandy beach and a mild climate said to be favourable for invalids suffering from pulmonary complaints. Arcachon is twinned with five cities. History On 2 May 1857, Emperor Napoleon III signed an imperial decree declaring that Arcachon was now an autonomous municipality; coincidentally, the railway line extension from Bordeaux to Arcachon had been completed that same year. At that time, Arcachon was scarcely more than a forest of pine trees, oaks and strawberry trees (arbutus), with no road links and few real houses, with a population fewer than 400 people, mostly fishermen and peasants. In earlier years, when some hygienists began to recommend sea bathing, three sea establishments were laid out by investors to attract the Bordeaux bourgeoisie and other wealthy people. This was the beginning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
