Magnes Sive De Arte Magnetica
''Magnes sive de Arte Magnetica'' ("''The Lodestone, or the Magnetic Art''") is a 1641 work by the Jesuit scholar Athanasius Kircher. It was dedicated to Ferdinand III, Holy Roman Emperor, Emperor Ferdinand III and printed in Rome by Hermann Scheuss. It developed the ideas set out in his earlier ''Ars Magnesia'' and argued that the universe is governed by universal physical forces of attraction and repulsion. These were, as described in the motto in the book's first illustration, 'hidden nodes' of connection. The force that drew things together in the physical world was, he argued, the same force that drew people's souls towards God. The work is divided into three books: 1.''De natura et facultatibus magnetis'' (Of the nature and properties of magnets), 2.''Magnes applicatus'' (Applications of magnets), 3.''Mundus sive catena magnetica'' (The world or the magnetic chain). It is noted for the first use of the term 'electromagnetism'. The Earth’s magnetic field The question of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert Fludd
Robert Fludd, also known as Robertus de Fluctibus (17 January 1574 – 8 September 1637), was a prominent English Paracelsian physician with both scientific and occult interests. He is remembered as an astrologer, mathematician, cosmologist, Qabalist and Rosicrucian. Fludd is best known for his compilations in occult philosophy. He had a celebrated exchange of views with Johannes Kepler concerning the scientific and hermetic approaches to knowledge. Early life He was born at Milgate House, Bearsted, Kent, not too long before 17 January 1573/4. He was the son of Sir Thomas Fludd, a high-ranking governmental official (Queen Elizabeth I's treasurer for war in Europe), and Member of Parliament. His mother was Elizabeth Andrews Fludd. A collage of 12 Coats of Arms of Fludd ancestors are shown in the painting above his right shoulder. His paternal arms goes back to Rhirid Flaidd whose name originates from Welsh meaning bloody or red wolf. Education He entered St John's Col ...

Electromagnetism
In physics, electromagnetism is an interaction that occurs between particles with electric charge. It is the second-strongest of the four fundamental interactions, after the strong force, and it is the dominant force in the interactions of atoms and molecules. Electromagnetism can be thought of as a combination of electricity and magnetism, two distinct but closely intertwined phenomena. In essence, electric forces occur between any two charged particles, causing an attraction between particles with opposite charges and repulsion between particles with the same charge, while magnetism is an interaction that occurs exclusively between ''moving'' charged particles. These two effects combine to create electromagnetic fields in the vicinity of charge particles, which can exert influence on other particles via the Lorentz force. At high energy, the weak force and electromagnetic force are unified as a single electroweak force. The electromagnetic force is responsible for many o ...

Magnetism
Magnetism is the class of physical attributes that are mediated by a magnetic field, which refers to the capacity to induce attractive and repulsive phenomena in other entities. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomena of electromagnetism. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets, producing magnetic fields themselves. Demagnetizing a magnet is also possible. Only a few substances are ferromagnetic; the most common ones are iron, cobalt, and nickel and their alloys. The rare-earth metals neodymium and samarium are less common examples. The prefix ' refers to iron because permanent magnetism was first observed in lodestone, a form of natural iron ore called magnetite, Fe3O4. All substances exhibit some type of ...

Niccolò Cabeo
Niccolò Cabeo, SJ (also known as Nicolaus Cabeus; February 26, 1586 – June 30, 1650) was an Italian Jesuit philosopher, theologian, engineer and mathematician. Biography He was born in Ferrara in 1586, and was educated at the Jesuit college in Parma beginning in 1602. He passed the next two years in Padua and spent 1606–07 studying in Piacenza before completing three years (1607–10) of study in philosophy at Parma. He spent another four years (1612–1616) studying theology in Parma and another year’s apprenticeship at Mantua. He then taught theology and mathematics in Parma, then in 1622 he became a preacher. For a time he received patronage of the Dukes of Mantua and the Este in Ferrara. During this time he was involved in hydraulics projects. He would later return to teach mathematics again in Genoa, the city where he would die in 1650. He is noted for his contributions to physics experiments and observations. He observed the experiments of Giovanni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leonardo Garzoni
Leonardo Garzoni (Venice, Italy, 1543 – Venice, Italy, 10 March 1592) was a Jesuit Natural philosophy, natural philosopher. Life The little data we have about Garzoni's life are the brief notices registered on official documents of the Society of Jesus. From these sources we know that Garzoni was born into a patrician family and that he began his philosophical studies before 1565. About 1566 he joined a congregation near to the Jesuits’ College in Brescia and entered the Society of Jesus in 1567 or 1568. In 1568 he lectured in logic in Parma and in 1573 he was a third–year student in theology in Padua. On 9 June 1579 he took his four vows in Brescia and from 1579 he lived, as a confessor, in Venice. After a stay in Verona (about 1588) he came back to Venice, where he died. Works Garzoni's only extant work, the ''Due trattati sopra la natura, e le qualità della calamita'', is the first known example of a modern treatment of magnetic phenomena. Written in years near 1580 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Gellibrand
Henry Gellibrand (1597–1637) was an English mathematician. He is known for his work on the Earth's magnetic field. He discovered that magnetic declination – the angle of dip of a compass needle – is not constant but changes over time. He announced this in 1635, relying on previous observations by others, which had not yet been correctly interpreted. He was the son of the physician Henry Gellibrand (1568–1615) and Mary Faversham. His four younger brothers were John, Edward, Thomas and Samuel. Samuel Gellibrand became a prominent seventeenth-century London bookseller.Henry Plomer (1907) A Dictionary of the Booksellers and Printers who Were at Work in England, Scotland and Ireland from 1641 to 1667 He also devised a method for measuring longitude, based on eclipses. The mathematical tables of Henry Briggs, consisting of logarithms of trigonometric functions, were published by Gellibrand in 1633 as ''Trigonometria Britannica''. He was Professor at Gresham College, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Folio
The term "folio" (), has three interconnected but distinct meanings in the world of books and printing: first, it is a term for a common method of arranging sheets of paper into book form, folding the sheet only once, and a term for a book made in this way; second, it is a general term for a sheet, leaf or page in (especially) manuscripts and old books; and third, it is an approximate term for the size of a book, and for a book of this size. First, a folio (abbreviated fo or 2o) is a book or pamphlet made up of one or more full sheets of paper, on each of which four pages of text are printed, two on each side; each sheet is then folded once to produce two leaves. Each leaf of a folio book thus is one half the size of the original sheet. Ordinarily, additional printed folio sheets would be inserted inside one another to form a group or "gathering" of leaves prior to binding the book. Second, folio is used in terms of page numbering for some books and most manuscripts that ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaspar Schott
Gaspar Schott (German: ''Kaspar'' (or ''Caspar'') ''Schott''; Latin: ''Gaspar Schottus''; 5 February 1608 – 22 May 1666) was a German Jesuit and scientist, specializing in the fields of physics, mathematics and natural philosophy, and known for his industry. Biography He was born at Bad Königshofen im Grabfeld. It is probable, but not certain, that his early education was at the Jesuit College at Würzburg. In any case, at the age of 19 he joined the Society of Jesus, entering the novitiate at Trier on 30 October 1627. After two years of novitiate training, he matriculated at the University of Würzburg on 6 November 1629 to begin a three-year study of Philosophy, following the normal academic path prescribed for Jesuit seminarians. Owing to the Swedish invasion of Würzburg in October 1631, the Jesuit community fled the city. Schott went, first to the Jesuit seminary of Tournai in Belgium, and subsequently, in 1633, to Caltagirone in Sicily, where he continued his study of T ...

Egg Of Columbus
An egg of Columbus or Columbus' egg ( it, uovo di Colombo ) refers to a brilliant idea or discovery that seems simple or easy after the fact. The expression refers to an apocryphal story, dating from at least the 16th century, in which it is said that Christopher Columbus, having been told that finding a new trade route was inevitable and no great accomplishment, challenges his critics to make an egg stand on its tip. After his challengers give up, Columbus does it himself by tapping the egg on the table to flatten its tip. The story is often alluded to when discussing creativity. The term has also been used as the trade name of a tangram puzzle and several mechanical puzzles. It also shows that anything can be done by anyone with the right set of skills; however, not everyone knows how to do it. Source of the story The Columbus egg story may have originated with Italian historian and traveler Girolamo Benzoni. In his book ''History of the New World'', published in 1565, he w ...

Galileo
Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 – 8 January 1642) was an Italian astronomer, physicist and engineer, sometimes described as a polymath. Commonly referred to as Galileo, his name was pronounced (, ). He was born in the city of Pisa, then part of the Duchy of Florence. Galileo has been called the "father" of observational astronomy, modern physics, the scientific method, and modern science. Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of pendulums and "hydrostatic balances". He invented the thermoscope and various military compasses, and used the telescope for scientific observations of celestial objects. His contributions to observational astronomy include telescopic confirmation of the phases of Venus, observation of the four largest satellites of Jupiter, observation of Saturn's rings, and an ...
