Howard Grubb
Sir Howard Grubb (28 July 1844 – 16 September 1931) was an optical designer from Dublin, Ireland. He was head of a family firm that made large optical telescopes, telescope drive controls, and other optical instruments. He is also noted for his work to perfect the periscope and inventing the reflector sight. Biography Howard Grubb was one of eight children of Thomas, founder of the Grubb Telescope Company so Howard developed an early interest in optics. He began his studies in Trinity College Dublin in 1863, but did not complete his degree. After training to be a civil engineer, Howard joined his father's firm in 1864 and gained the reputation of a first class producer of telescopes. In 1871 he married Mary Walker with whom he had six children. Grubb was elected Fellow of the Royal Society in 1883 and of the Royal Astronomical Society in 1870. In 1876, he was awarded an honorary Masters in Engineering by Trinity College Dublin. In 1887 he was knighted by Lord Lieutenant at ...

Reflecting Telescope
A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century by Isaac Newton as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic aberration. Although reflecting telescopes produce other types of optical aberrations, it is a design that allows for very large diameter objectives. Almost all of the major telescopes used in astronomy research are reflectors. Many variant forms are in use and some employ extra optical elements to improve image quality or place the image in a mechanically advantageous position. Since reflecting telescopes use mirrors, the design is sometimes referred to as a catoptrics, catoptric telescope. From the time of Newton to the 1800s, the mirror itself was made of metal usually speculum metal. This type included Newton's first designs and eve ...

Birkenhead
Birkenhead (; cy, Penbedw) is a town in the Metropolitan Borough of Wirral, Merseyside, England; historically, it was part of Cheshire until 1974. The town is on the Wirral Peninsula, along the south bank of the River Mersey, opposite Liverpool. At the 2011 census, it had a population of 88,818. Birkenhead Priory and the Mersey Ferry were established in the 12th century. In the 19th century, Birkenhead expanded greatly as a consequence of the Industrial Revolution. Birkenhead Park and Hamilton Square were laid out as well as the first street tramway in Britain. The Mersey Railway connected Birkenhead and Liverpool with the world's first tunnel beneath a tidal estuary; the shipbuilding firm Cammell Laird and a seaport were established. In the second half of the 20th century, the town suffered a significant period of decline, with containerisation causing a reduction in port activity. The Wirral Waters development is planned to regenerate much of the dockland. Toponymy The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Ferry
Rock Ferry is an area of Birkenhead on the Wirral Peninsula, England. Administratively it is a ward of the Metropolitan Borough of Wirral. Before local government reorganisation on 1 April 1974, it was part of the county of Cheshire. At the 2011 Census, the population was 14,298. History There are references to a ferry as early as 1357. Ferry services were extended at the start of the 19th century, with steam ferries providing a faster, cheaper and more reliable service than had previously been allowed. By 1800 there was already an inn known as the Rock Ferry House, which was reputed to have been used by William IV as Duke of Clarence, hence the use of the term "Royal" for establishments such as the Royal Rock Hotel (the original inn, much enlarged in 1836) and the Royal Rock Beagles, set up in 1845. From the 1560s onwards Derby House, an occasional seat of the Minshull family, covered most of the grounds covered by present-day Rock Ferry. It was enlarged in 1834 to a design b ...

Isaac Roberts's Observatory
Isaac; grc, Ἰσαάκ, Isaák; ar, إسحٰق/إسحاق, Isḥāq; am, ይስሐቅ is one of the three patriarchs of the Israelites and an important figure in the Abrahamic religions, including Judaism, Christianity, and Islam. He was the son of Abraham and Sarah, the father of Jacob and Esau, and the grandfather of the twelve tribes of Israel. Isaac's name means "he will laugh", reflecting the laughter, in disbelief, of Abraham and Sarah, when told by God that they would have a child., He is the only patriarch whose name was not changed, and the only one who did not move out of Canaan. According to the narrative, he died aged 180, the longest-lived of the three patriarchs. Etymology The anglicized name "Isaac" is a transliteration of the Hebrew name () which literally means "He laughs/will laugh." Ugaritic texts dating from the 13th century BCE refer to the benevolent smile of the Canaanite deity El. Genesis, however, ascribes the laughter to Isaac's parents, Abrah ...

Roberts (crater)
Roberts is a lunar impact crater that is located in the far northern latitudes on the far side of the Moon The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of .... It is located to the east-southeast of the crater Karpinskiy, and to the northwest of Sommerfeld. To the north is Thiessen. This is a heavily worn and eroded crater with a rounded outer rim that is incised and damaged by multiple smaller craters. Little of the original rim still remains besides a rounded and irregular ridge in the surface. The interior floor is also marked by a number of small craters, the most notable being a crater near the south-southeastern inner wall. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest ...

Edward Emerson Barnard
Edward Emerson Barnard (December 16, 1857 – February 6, 1923) was an American astronomer. He was commonly known as E. E. Barnard, and was recognized as a gifted observational astronomer. He is best known for his discovery of the high proper motion of Barnard's Star in 1916, which is named in his honor. Early life Barnard was born in Nashville, Tennessee, to Reuben Barnard and Elizabeth Jane Barnard (''née'' Haywood), and had one brother. His father died three months before his birth, so he grew up in an impoverished family and did not receive much in the way of formal education. His first interest was in the field of photography, and he became a photographer's assistant at the age of nine. He later developed an interest in astronomy. In 1876 he purchased a refractor telescope, and in 1881 he discovered his first comet, but failed to announce his discovery. He found his second comet later the same year and a third in 1882. While he was still working at a photography studio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Herschel
Frederick William Herschel (; german: Friedrich Wilhelm Herschel; 15 November 1738 – 25 August 1822) was a German-born British astronomer and composer. He frequently collaborated with his younger sister and fellow astronomer Caroline Herschel (1750–1848). Born in the Electorate of Hanover, William Herschel followed his father into the military band of Hanover, before emigrating to Great Britain in 1757 at the age of nineteen. Herschel constructed his first large telescope in 1774, after which he spent nine years carrying out sky surveys to investigate double stars. Herschel published catalogues of nebulae in 1802 (2,500 objects) and in 1820 (5,000 objects). The resolving power of the Herschel telescopes revealed that many objects called nebulae in the Messier catalogue were actually clusters of stars. On 13 March 1781 while making observations he made note of a new object in the constellation of Gemini. This would, after several weeks of verification and consultation ...
