William Leitch (scientist)
William Leitch (20 May 1814 – 9 May 1864) was a Scottish astronomer, naturalist and mathematician, and a minister of the Church of Scotland. Leitch studied mathematics and science at the University of Glasgow, and moved to Canada in 1860 to take the post of principal at Queen's University. Space historian Robert Godwin published in October 2015 his discovery that Leitch gave the first modern scientific explanation of the potential for space exploration using rockets (1861). Leitch was said to be "a distinguished astronomer, naturalist and mathematician", and his proposal for rocket spaceflight came four decades prior to more well-known proposals by Konstantin Tsiolkovsky (1903), Robert Esnault-Pelterie (1913), Robert H. Goddard (1914), and Hermann Oberth (1923). Leitch's rocket spaceflight description was first provided in his 1861 essay "A Journey Through Space", which was later published in his book ''God's Glory in the Heavens'' (1862).

Rothesay, Bute
Rothesay ( ; gd, Baile Bhòid ) is the principal town on the Isle of Bute, in the council area of Argyll and Bute, Scotland. It lies along the coast of the Firth of Clyde. It can be reached by ferry from Wemyss Bay, which offers an onward rail link to Glasgow. At the centre of the town is the 13th-century ruin Rothesay Castle, unique in Scotland for its circular plan. Etymology In modern Scottish Gaelic, Rothesay is known as , meaning 'town of Bute'. The English-language name, which was written as ''Rothersay'' in 1321, ''Rosay'' around 1400, and ''Rothissaye'' around 1500, originally referred to the castle. Since the castle was surrounded by a moat connected to the sea, the name may have originally meant 'Rother's Isle' (the Old Norse suffix means "isle"), or it may be an alteration of the Gaelic word , meaning 'fort'. History The old town centred on Rothesay Castle, which was built in the 13th century. The castle has long stood in ruins, but it is nevertheless picturesque ...

Konstantin Tsiolkovsky
Konstantin Eduardovich Tsiolkovsky (russian: Константи́н Эдуа́рдович Циолко́вский , , p=kənstɐnʲˈtʲin ɪdʊˈardəvʲɪtɕ tsɨɐlˈkofskʲɪj , a=Ru-Konstantin Tsiolkovsky.oga; – 19 September 1935) was a Russian and Soviet rocket scientist who pioneered astronautic theory. Along with the Frenchman Robert Esnault-Pelterie, the Germans Hermann Oberth and Fritz von Opel, and the American Robert H. Goddard, he is one of the founding fathers of modern rocketry and astronautics. His works later inspired leading Soviet rocket-engineers Sergei Korolev and Valentin Glushko, who contributed to the success of the Soviet space program. Tsiolkovsky spent most of his life in a log house on the outskirts of Kaluga, about southwest of Moscow. A recluse by nature, his unusual habits made him seem bizarre to his fellow townsfolk. Early life Tsiolkovsky was born in Izhevskoye (now in Spassky District, Ryazan Oblast), in the Russian Empire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disruption Of 1843
The Disruption of 1843, also known as the Great Disruption, was a schism in 1843 in which 450 evangelical ministers broke away from the Church of Scotland to form the Free Church of Scotland. The main conflict was over whether the Church of Scotland or the British Government had the power to control clerical positions and benefits. The Disruption came at the end of a bitter conflict within the Church of Scotland, and had major effects in the church and upon Scottish civic life. The patronage issue "The Church of Scotland was recognised by Acts of the Parliament as the national church of the Scottish people". Particularly under John Knox and later Andrew Melville, the Church of Scotland had always claimed an inherent right to exercise independent spiritual jurisdiction over its own affairs. To some extent, this right was recognised by the Claim of Right of 1689, which ended royal and parliamentary interference in the order and worship of the church. It was ratified by the ...

Church Of Scotland
The Church of Scotland ( sco, The Kirk o Scotland; gd, Eaglais na h-Alba) is the national church in Scotland. The Church of Scotland was principally shaped by John Knox, in the Reformation of 1560, when it split from the Catholic Church and established itself as a church in the reformed tradition. The church is Calvinist Presbyterian, having no head of faith or leadership group and believing that God invited the church's adherents to worship Jesus. The annual meeting of its general assembly is chaired by the Moderator of the General Assembly of the Church of Scotland. The Church of Scotland celebrates two sacraments, Baptism and the Lord's Supper, as well as five other rites, such as Confirmation and Matrimony. The church adheres to the Bible and the Westminster Confession of Faith, and is a member of the World Communion of Reformed Churches. History Presbyterian tradition, particularly that of the Church of Scotland, traces its early roots to the church foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Pringle Nichol
John Pringle Nichol FRSE FRAS (13 January 1804 – 19 September 1859) was a Scottish educator, phrenologist, astronomer and economist who did much to popularise astronomy in a manner that appealed to nineteenth century tastes. Early life Born at Huntly Hill, near Brechin, Angus, Nichol was the son of a gentleman farmer and was educated at the local grammar school and then studied mathematics and natural philosophy (physics) at King's College, University of Aberdeen. He then changed to study divinity. He was licensed as a preacher and became a highly effective communicator, but the impact of phrenological thinking led him to abandon the Church for education. Nichol held a number of posts in education and journalism and corresponded with many leading thinkers of the times, including John Stuart Mill. He clearly made some impression in economics as James Mill and Nassau Senior nominated him as Jean-Baptiste Say's successor as professor of political economy at the Collège d ...

Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Master Of Arts (Scotland)
The degree of Master of Arts (MA; , ) in Scotland is an undergraduate degree. The degree can be either a three-year general or four-year ''Honours degree'' in humanities or social sciences, awarded by one of several institutions. Chiefly, these are the ancient universities of Scotland—the University of St Andrews, the University of Glasgow, the University of Aberdeen, and the University of Edinburgh. Other institutions which execute undergraduate MA programmes include the University of Dundee because of its history as a constituent college of the University of St Andrews, or Heriot-Watt University at honours level only. The first two years of the Scottish Master of Arts consist of ordinary Bachelor level courses; however, after these, students who are accepted to pursue the Honours route will complete more advanced subjects and write a dissertation in their fourth year. Students who choose to do a "general" degree will complete their third year at a lower level of speciali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenock
Greenock (; sco, Greenock; gd, Grianaig, ) is a town and administrative centre in the Inverclyde council area in Scotland, United Kingdom and a former burgh within the historic county of Renfrewshire, located in the west central Lowlands of Scotland. It forms part of a contiguous urban area with Gourock to the west and Port Glasgow to the east. The 2011 UK Census showed that Greenock had a population of 44,248, a decrease from the 46,861 recorded in the 2001 UK Census. It lies on the south bank of the Clyde at the "Tail of the Bank" where the River Clyde deepens into the Firth of Clyde. History Name Place-name scholar William J. Watson wrote that "Greenock is well known in Gaelic as Grianáig, dative of grianág, a sunny knoll". The Scottish Gaelic place-name ''Grianaig'' is relatively common, with another (Greenock) near Callander in Menteith (formerly in Perthshire) and yet another at Muirkirk in Kyle, now in East Ayrshire. R. M. Smith in (1921) described ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orson Desaix Munn
Orson Desaix Munn (June 11, 1824 – February 28, 1907) was the publisher of ''Scientific American''. Biography Orson Desaix Munn was born on June 11, 1824, in Monson, Massachusetts. He received his education at the academy in his native town, and, deciding on a business career, went to work for a bookstore in Springfield. After two years of this experience, he returned to accept a more important commercial trust in Monson, but soon found his way to New York City. He took over the publishing operations of Munn & Company, a New York patent firm, with Salem Howe Wales and Alfred Ely Beach as editor. With Beach, he bought the six-month-old ''Scientific American'' magazine from Rufus Porter. The purchase price of this property was less than $1,000, and it included a subscription list of 200 names. Porter continued as editor, and the enterprise, placed on a sound business basis, at once proved a success. It was the first popular scientific journal in the United States, and it is n ...

Robert Hutchings Goddard
Robert Hutchings Goddard (October 5, 1882 – August 10, 1945) was an American engineer, professor, physicist, and inventor who is credited with creating and building the world's first liquid-fueled rocket. Goddard successfully launched his rocket on March 16, 1926, which ushered in an era of space flight and innovation. He and his team launched 34 rockets between 1926 and 1941, achieving altitudes as high as and speeds as fast as 885 km/h (550 mph). Goddard's work as both theorist and engineer anticipated many of the developments that would make spaceflight possible. He has been called the man who ushered in the Space Age. Two of Goddard's 214 patented inventions, a multi-stage rocket (1914), and a liquid-fuel rocket (1914), were important milestones toward spaceflight. His 1919 monograph ''A Method of Reaching Extreme Altitudes'' is considered one of the classic texts of 20th-century rocket science. Goddard successfully pioneered modern methods such as ...

Vacuum
A vacuum is a space devoid of matter. The word is derived from the Latin adjective ''vacuus'' for "vacant" or " void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a ''perfect'' vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is considerably lower than atmospheric pressure. The Latin term ''in vacuo'' is used to describe an object that is surrounded by a vacuum. The ''quality'' of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. But h ...

Newton's Laws Of Motion
Newton's laws of motion are three basic laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it. These laws can be paraphrased as follows: # A body remains at rest, or in motion at a constant speed in a straight line, unless acted upon by a force. # When a body is acted upon by a force, the time rate of change of its momentum equals the force. # If two bodies exert forces on each other, these forces have the same magnitude but opposite directions. The three laws of motion were first stated by Isaac Newton in his '' Philosophiæ Naturalis Principia Mathematica'' (''Mathematical Principles of Natural Philosophy''), originally published in 1687. Newton used them to investigate and explain the motion of many physical objects and systems, which laid the foundation for classical mechanics. In the time since Newton, the conceptual content of classical physics has been reformulated in alternative ways, involving diff ...
