Robert Stawell Ball
Sir Robert Stawell Ball (1 July 1840 – 25 November 1913) was an Irish astronomer who founded the screw theory. He was Royal Astronomer of Ireland at Dunsink Observatory. Life He was the son of naturalist Robert Ball, and Amelia Gresley Hellicar. He was born in Dublin. and was educated at Trinity College Dublin where he won a scholarship in 1859 and was a senior moderator in both ''mathematics'' and ''experimental and natural science'' in 1861. Ball worked for Lord Rosse from 1865 to 1867. In 1867, he became Professor of Applied Mathematics at the Royal College of Science in Dublin. There he lectured on mechanics and published an elementary account of the science. In 1873, he became a Fellow of the Royal Society. In 1874, he was appointed Royal Astronomer of Ireland and Andrews Professor of Astronomy in the University of Dublin at Dunsink Observatory. Ball contributed to the science of kinematics by delineating the screw displacement: :When Ball and the screw theorists spe ...

It is Ireland's premier List of Irish learned societies, learned society and one its leading List of Irish cultural institutions, cultural institutions. The Academy was established in 1785 and granted a royal charter in 1786. the RIA has around 600 members, regular members being Irish residents elected in recognition of their academic achievements, and Honorary Members similarly qualified but based abroad; a small number of members are elected in recognition of non-academic contributions to society. Until the late 19th century the Royal Irish Academy was the owner of the main national collection of Irish antiquities. It presented its collection of archaeological artefacts and similar items, which included such famous pieces as the Tara Brooch, the Cross of Cong and the Ardagh Chalice to what is now the Na ...

Cunningham Medal
The Cunningham Medal is the premier award of the Royal Irish Academy. It is awarded every three years in recognition of "outstanding contributions to scholarship and the objectives of the Academy". History It was which was established in 1796 at the bequest of barrister Timothy Cunningham of Gray's Inn. After a period of uncertainty and experimentation regarding the terms and conditions of the award, it was agreed in 1848 that the medals would be open to the authors of works or essays in the areas of Science, Polite Literature and Antiquities, published in Ireland or about Irish subjects. After 1885, the academy stopped giving the award, but it was revived in 1989 for the bicentennial of Cunningham's gift. Recipients The following persons have been awarded the Cunningham Medal: *1796: Thomas Wallace *1800: Theophilus Swift (writing, poetry) *1805: William Preston (poetry) *1818: John Brinkley (astronomy) *1827: John D'Alton (history) *1830: George Petrie (history) *1833: G ...

Screw Displacement
A screw axis (helical axis or twist axis) is a line that is simultaneously the axis of rotation and the line along which translation of a body occurs. Chasles' theorem shows that each Euclidean displacement in three-dimensional space has a screw axis, and the displacement can be decomposed into a rotation about and a slide along this screw axis. Plücker coordinates are used to locate a screw axis in space, and consist of a pair of three-dimensional vectors. The first vector identifies the direction of the axis, and the second locates its position. The special case when the first vector is zero is interpreted as a pure translation in the direction of the second vector. A screw axis is associated with each pair of vectors in the algebra of screws, also known as screw theory. The spatial movement of a body can be represented by a continuous set of displacements. Because each of these displacements has a screw axis, the movement has an associated ruled surface known as a ''screw su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinematics
Kinematics is a subfield of physics, developed in classical mechanics, that describes the Motion (physics), motion of points, Physical object, bodies (objects), and systems of bodies (groups of objects) without considering the forces that cause them to move. Kinematics, as a field of study, is often referred to as the "geometry of motion" and is occasionally seen as a branch of mathematics. A kinematics problem begins by describing the geometry of the system and declaring the initial conditions of any known values of position, velocity and/or acceleration of points within the system. Then, using arguments from geometry, the position, velocity and acceleration of any unknown parts of the system can be determined. The study of how forces act on bodies falls within kinetics (physics), kinetics, not kinematics. For further details, see analytical dynamics. Kinematics is used in astrophysics to describe the motion of celestial bodies and collections of such bodies. In mechanical engin ...

Andrews Professor Of Astronomy
The Andrews Professor of Astronomy is a chair in astronomy in Trinity College Dublin was established in 1783 in conjunction with the establishment of Dunsink Observatory. Dunsink was founded in 1785 following a bequest by Provost Francis Andrews in 1774, which also funded the professorship. It was regulated by a new Statute of Trinity College Dublin, which required the professor to "make regular observations of the heavenly bodies ... and of the sun, moon and planets". The chair was suspended in 1921 and in 1947 the observatory passed to Dublin Institute for Advanced Studies. In 1984 the professorship was revived as an honorary title in the Department of Pure and Applied Mathematics. From 1793, under letters patent of King George III, the Andrews Professor held the title Royal Astronomer of Ireland. This title fell vacant in 1921 and has not been revived. List of the professors * 1783-1790: Henry Ussher (1741–1790) * 1790-1827: John Brinkley (1763–1835) * 1827-1865: Willi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechanics
Mechanics (from Ancient Greek: μηχανική, ''mēkhanikḗ'', "of machines") is the area of mathematics and physics concerned with the relationships between force, matter, and motion among physical objects. Forces applied to objects result in displacements, or changes of an object's position relative to its environment. Theoretical expositions of this branch of physics has its origins in Ancient Greece, for instance, in the writings of Aristotle and Archimedes (see History of classical mechanics and Timeline of classical mechanics). During the early modern period, scientists such as Galileo, Kepler, Huygens, and Newton laid the foundation for what is now known as classical mechanics. As a branch of classical physics, mechanics deals with bodies that are either at rest or are moving with velocities significantly less than the speed of light. It can also be defined as the physical science that deals with the motion of and forces on bodies not in the quantum realm ...
