Margaret Bryan (philosopher)
Margaret Bryan (c. 1759 – 31 March 1836) was an English natural philosopher and educator and the author of three scientific textbooks. A pioneer of female education, she taught science to women and girls from her schools in Margate and London. The first 'Bryan House' school was in Margate, Kent above the yet-to-be-discovered Margate Caves, and the second was in Blackheath, London. Margaret also later offered private tuition from Cadogan Place in Chelsea. Her first known work was ''A Compendious System of Astronomy'' (1797), collecting her lectures on astronomy. She later published ''Lectures on Natural Philosophy'' (1806), a textbook on the fundamentals of physics and astronomy, and ''An'' ''Astronomical and Geographical Class Book for the Use of Schools and Private Families,'' a thin octavo, in 1815. Life Although some unverified speculations appeared in 2021, personal information about Margaret Bryan was discovered when genealogical research published in 2023 uncover ...

Natural Philosopher
Natural philosophy or philosophy of nature (from Latin ''philosophia naturalis'') is the philosophical study of physics Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which r ..., that is, nature and the physical universe. It was dominant before the development of modern science. From the ancient world (at least since Aristotle) until the 19th century, ''natural philosophy'' was the common term for the study of physics (nature), a broad term that included botany, zoology, anthropology, and chemistry as well as what we now call physics. It was in the 19th century that the concept of science received its modern shape, with different subjects within science emerging, such as astronomy, biology, and physics. Institutions and communities devoted to science were founded. Isaac Newton's book ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Nutter
William Nutter (c. 1759–1802) was an English engraver and draughtsman. Life Born about 1759, Nutter became a pupil of John Raphael Smith. He worked exclusively as a stipple engraver, in the style of Francesco Bartolozzi. Nutter exhibited some allegorical designs at the Royal Academy in 1782 and 1783. He died at his residence in Somers Town, 14 March 1802, in his 44th year, and was buried in the graveyard of Whitefield's Tabernacle, Tottenham Court Road. Works Nutter's works are dated from 1780 to 1800. He executed plates after leading English artists of his time, a large proportion of them being from miniatures by Samuel Shelley. His works include: * ''The Ale House Door'' and ''Coming from Market'', after Henry Singleton; * ''Celia overheard by Young Delvile'', after Thomas Stothard; * ''Saturday Evening'', and ''Sunday Morning'', after William Redmore Bigg; * ''The Moralist'', after John Raphael Smith; * ''Burial of General Fraser'', after John Graham; * portraits o ...

Kite Experiment
The kite experiment is a scientific experiment in which a kite with a pointed, conductive wire attached to its apex is flown near thunder clouds to collect electricity from the air and conduct it down the wet kite string to the ground. It was proposed and may have been conducted by Benjamin Franklin with the assistance of his son William Franklin. The experiment's purpose was to uncover the unknown facts about the nature of lightning and electricity, and with further experiments on the ground, to demonstrate that lightning and electricity were the result of the same phenomenon. Background Speculations of Jean-Antoine Nollet had led to the issue of the electrical nature of lightning being posed as a prize question at Bordeaux in 1749. In 1750, it was the subject of public discussion in France, with a dissertation of Denis Barberet receiving a prize in Bordeaux; Barberet proposed a cause in line with the triboelectric effect. The same year, Franklin reversed his previous skeptici ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benjamin Franklin
Benjamin Franklin ( April 17, 1790) was an American polymath who was active as a writer, scientist, inventor, statesman, diplomat, printer, publisher, and political philosopher. Encyclopædia Britannica, Wood, 2021 Among the leading intellectuals of his time, Franklin was one of the Founding Fathers of the United States, a drafter and signer of the United States Declaration of Independence, and the first United States Postmaster General. As a scientist, he was a major figure in the American Enlightenment and the history of physics for his studies of electricity, and for charting and naming the current still known as the Gulf Stream. As an inventor, he is known for the lightning rod, bifocals, and the Franklin stove, among others. He founded many civic organizations, including the Library Company, Philadelphia's first fire department, and the University of Pennsylvania. Isaacson, 2004, p. Franklin earned the title of "The First American" for his early and indefa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galileo Galilei
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 a ...

Isaac Newton
Sir Isaac Newton (25 December 1642 – 20 March 1726/27) was an English mathematician, physicist, astronomer, alchemist, theologian, and author (described in his time as a "natural philosopher"), widely recognised as one of the greatest mathematicians and physicists and among the most influential scientists of all time. He was a key figure in the philosophical revolution known as the Enlightenment. His book (''Mathematical Principles of Natural Philosophy''), first published in 1687, established classical mechanics. Newton also made seminal contributions to optics, and shares credit with German mathematician Gottfried Wilhelm Leibniz for developing infinitesimal calculus. In the , Newton formulated the laws of motion and universal gravitation that formed the dominant scientific viewpoint for centuries until it was superseded by the theory of relativity. Newton used his mathematical description of gravity to derive Kepler's laws of planetary motion, account for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Heath (engraver)
James Heath (19 April 1757 – 15 November 1834) was a British engraver. He enjoyed the patronage of George III and successive monarchs. Life and work Heath was born in Newgate, London, the son of George Heath, a bookbinder (d. 1773). He was articled to the engraver Joseph Collyer the younger, an exacting master who required steady application from his pupil - as a result, Heath acquired a great mechanical skill in his art. His earliest engravings were of portraits in the collected edition of Horace Walpole's works. He was subsequently employed to engrave Thomas Stothard's designs for Harrison's ''The Novelist's Magazine'' and Bell's ''Poets of Great Britain'', and the taste and dexterity with which he rendered these small illustrations brought this style of illustration into great popularity. He made many engravings after artists such as Stothard, Smirke, and others, and these were to be found in publications such as: Sharpe's ''British Classics'', the ''Lady's Poetic ...

Acoustics
Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an Acoustical engineering, acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries. Hearing (sense), Hearing is one of the most crucial means of survival in the animal world and speech is one of the most distinctive characteristics of human development and culture. Accordingly, the science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production, warfare and more. Likewise, animal species such as songbirds and frogs use sound and hearing as a key element of mating rituals or for marking territories. Art, ...

Pneumatics
Pneumatics (from Greek ‘wind, breath’) is a branch of engineering that makes use of gas or pressurized air. Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically-powered compressor powers cylinders, air motors, pneumatic actuators, and other pneumatic devices. A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors, and hydraulic actuators. Pneumatics also has applications in dentistry, construction, mining, and other areas. Gases used in pneumatic systems Pneumatic systems in fixed installations, such as factories, use compressed air because a sustainable supply can be made by compressing atmospheric air. The air usually has moisture removed, and a small quantity of oil is added at the compressor to prevent corrosion and lubricate mechanical components. Factory-plumb ...

Optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be ...

Hydrostatics
Fluid statics or hydrostatics is the branch of fluid mechanics that studies the condition of the equilibrium of a floating body and submerged body " fluids at hydrostatic equilibrium and the pressure in a fluid, or exerted by a fluid, on an immersed body". It encompasses the study of the conditions under which fluids are at rest in stable equilibrium as opposed to fluid dynamics, the study of fluids in motion. Hydrostatics is a subcategory of fluid statics, which is the study of all fluids, both compressible or incompressible, at rest. Hydrostatics is fundamental to hydraulics, the engineering of equipment for storing, transporting and using fluids. It is also relevant to geophysics and astrophysics (for example, in understanding plate tectonics and the anomalies of the Earth's gravitational field), to meteorology, to medicine (in the context of blood pressure), and many other fields. Hydrostatics offers physical explanations for many phenomena of everyday life, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Critical Review (newspaper)
''The Critical Review'' was a British publication appearing from 1756 to 1817. It was first edited by Tobias Smollett, from 1756 to 1763. Contributors included Samuel Johnson, David Hume, John Hunter, and Oliver Goldsmith. Early years The Edinburgh printer Archibald Hamilton started publishing ''The Critical Review'' in 1756 with Tobias Smollett as its first editor. The content was mainly book reviews, which were often long and favourable, with copious verbatim quotations. The Tory and High Church perspectives of contributors came through clearly, however. Besides Smollett, the writers of the first two volumes have been identified as John Armstrong, Samuel Derrick, Thomas Francklin, and Patrick Murdoch. After a libel against Admiral Sir Charles Knowles in the ''Review'', Smollett was sentenced to a fine of £100 and three months in King's Bench Prison. In 1763 he retired from the ''Review'', but left it as an influential publication. Sources External links Full textsat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
