112-409: Michael Faraday ( / ˈ f ær ə d eɪ , - d i / ; 22 September 1791 – 25 August 1867) was an English physicist and chemist who contributed to the study of electromagnetism and electrochemistry . His main discoveries include the principles underlying electromagnetic induction , diamagnetism and electrolysis . Although Faraday received little formal education, as a self-made man , he

224-700: A master's degree like MSc, MPhil, MPhys or MSci. For research-oriented careers, students work toward a doctoral degree specializing in a particular field. Fields of specialization include experimental and theoretical astrophysics , atomic physics , biological physics , chemical physics , condensed matter physics , cosmology , geophysics , gravitational physics , material science , medical physics , microelectronics , molecular physics , nuclear physics , optics , particle physics , plasma physics , quantum information science , and radiophysics . The three major employers of career physicists are academic institutions, laboratories, and private industries, with

336-431: A science . Throughout Logic, Watts revealed his high conception of logic by stressing the practical side of logic, rather than the speculative side. According to Watts, as a practical art, logic can be really useful in any inquiry, whether it is an inquiry in the arts, or inquiry in the sciences, or inquiry of an ethical kind. Watts' emphasis on logic as a practical art distinguishes his book from others. By stressing

448-426: A changing magnetic field produces an electric field; this relation was modelled mathematically by James Clerk Maxwell as Faraday's law , which subsequently became one of the four Maxwell equations , and which have in turn evolved into the generalization known today as field theory . Faraday would later use the principles he had discovered to construct the electric dynamo , the ancestor of modern power generators and

560-740: A chemical battery. These experiments and inventions formed the foundation of modern electromagnetic technology. In his excitement, Faraday published results without acknowledging his work with either Wollaston or Davy. The resulting controversy within the Royal Society strained his mentor relationship with Davy and may well have contributed to Faraday's assignment to other activities, which consequently prevented his involvement in electromagnetic research for several years. From his initial discovery in 1821, Faraday continued his laboratory work, exploring electromagnetic properties of materials and developing requisite experience. In 1824, Faraday briefly set up

672-734: A circuit to study whether a magnetic field could regulate the flow of a current in an adjacent wire, but he found no such relationship. This experiment followed similar work conducted with light and magnets three years earlier that yielded identical results. During the next seven years, Faraday spent much of his time perfecting his recipe for optical quality (heavy) glass, borosilicate of lead, which he used in his future studies connecting light with magnetism. In his spare time, Faraday continued publishing his experimental work on optics and electromagnetism; he conducted correspondence with scientists whom he had met on his journeys across Europe with Davy, and who were also working on electromagnetism. Two years after

784-508: A classical education at King Edward VI School, Southampton , learning Latin , Greek , and Hebrew . Watts displayed a propensity for rhyme from an early age. He was once asked why he had his eyes open during prayers, to which he responded: A little mouse for want of stairs ran up a rope to say its prayers. He received corporal punishment for this, to which he cried: O father, father, pity take And I will no more verses make. Watts could not attend Oxford or Cambridge because he

896-441: A day, at 8   am, 12   noon and 4   pm. In his novel David Copperfield (1850), Charles Dickens has school master Dr. Strong quote from Watts' "Against Idleness and Mischief". In Herman Melville 's epic novel Moby-Dick (1851), a minor investor in the whaling ship Pequod is Charity Bildad, "a lean old lady of a most determined and indefatigable spirit, but withal very kindhearted" (chapter 20). Her brother,

1008-456: A definite determination of spectral change. Pieter Zeeman later used an improved apparatus to study the same phenomenon, publishing his results in 1897 and receiving the 1902 Nobel Prize in Physics for his success. In both his 1897 paper and his Nobel acceptance speech, Zeeman made reference to Faraday's work. In his work on static electricity, Faraday's ice pail experiment demonstrated that

1120-509: A departure from the conception of logic of most other authors. His conception of logic is more akin to that of the later, nineteenth-century logician, C. S. Peirce . Isaac Watts' Logic became the standard text on logic at Oxford , Cambridge , Harvard and Yale , being used at Oxford for well over 100 years. Charles Sanders Peirce , the nineteenth-century logician, wrote favourably of Watts' Logic . When preparing his own textbook, titled A Critick of Arguments: How to Reason (also known as

1232-686: A lecture at the Royal Institution with the magneto-electric spark apparatus. In 2002, Faraday was ranked number 22 in the BBC 's list of the 100 Greatest Britons following a UK-wide vote. Faraday has been commemorated on postage stamps issued by the Royal Mail . In 1991, as a pioneer of electricity he featured in their Scientific Achievements issue along with pioneers in three other fields ( Charles Babbage (computing), Frank Whittle (jet engine) and Robert Watson-Watt (radar)). In 1999, under

1456-412: A momentary current was induced in the other coil. This phenomenon is now known as mutual inductance . The iron ring-coil apparatus is still on display at the Royal Institution. In subsequent experiments, he found that if he moved a magnet through a loop of wire an electric current flowed in that wire. The current also flowed if the loop was moved over a stationary magnet. His demonstrations established that

1568-525: A new way of rendering the Psalms in verse for church services, proposing that they be adapted for hymns with a specifically Christian perspective. As Watts put it in the title of his 1719 metrical Psalter, the Psalms should be "imitated in the language of the New Testament." Besides writing hymns, Isaac Watts was also a theologian and logician , writing books and essays on these subjects. Isaac Watts

1680-510: A physics-related activity; a Doctorate or equivalent degree in Physics or a related field; or training or experience which, in the opinion of the Council, is equivalent to any of the above. Physicists may be a member of a physical society of a country or region. Physical societies commonly publish scientific journals, organize physics conferences and award prizes for contributions to the field of physics. Some examples of physical societies are

1792-400: A portrait of Faraday on his study wall, alongside those of Isaac Newton and James Clerk Maxwell. Physicist Ernest Rutherford stated, "When we consider the magnitude and extent of his discoveries and their influence on the progress of science and of industry, there is no honour too great to pay to the memory of Faraday, one of the greatest scientific discoverers of all time." Michael Faraday

1904-399: A practical and non-formal part of logic, Watts gave rules and directions for any kind of inquiry, including the inquiries of science and the inquiries of philosophy . These rules of inquiry were given in addition to the formal content of classical logic common to textbooks on logic from that time. Watts' conception of logic as being divided into its practical part and its speculative part marks

2016-416: A professional practice examination must also be passed. An exemption can be granted to a candidate that has practiced physics for at least seven years and provide a detailed description of their professional accomplishments which clearly demonstrate that the exam is not necessary. Work experience will be considered physics-related if it uses physics directly or significantly uses the modes of thought (such as

2128-697: A result of representations by the Prince Consort , Faraday was awarded a grace and favour house in Hampton Court in Middlesex, free of all expenses and upkeep. This was the Master Mason's House, later called Faraday House, and now No. 37 Hampton Court Road. In 1858 Faraday retired to live there. Having provided a number of various service projects for the British government, when asked by

2240-483: A series of nineteen Christmas lectures for young people, a series which continues today. The objective of the lectures was to present science to the general public in the hopes of inspiring them and generating revenue for the Royal Institution. They were notable events on the social calendar among London's gentry. Over the course of several letters to his close friend Benjamin Abbott, Faraday outlined his recommendations on

2352-401: A single "electricity" exists, and the changing values of quantity and intensity (current and voltage) would produce different groups of phenomena. Near the end of his career, Faraday proposed that electromagnetic forces extended into the empty space around the conductor. This idea was rejected by his fellow scientists, and Faraday did not live to see the eventual acceptance of his proposition by

2464-563: A speech to the Royal Society, Margaret Thatcher declared: "The value of his work must be higher than the capitalisation of all the shares on the Stock Exchange!" She borrowed his bust from the Royal Institution and had it placed in the hall of 10 Downing Street . In honor and remembrance of his great scientific contributions, several institutions have created prizes and awards in his name. This include: Faraday's books, with

2576-484: A total of 36 years in the Abney household, most of the time at Abney House, their second residence. (Lady Mary had inherited the manor of Stoke Newington in 1701 from her late brother Thomas Gunston.) On the death of Sir Thomas Abney in 1722, his widow Lady Mary and her unmarried daughter Elizabeth moved all her household to Abney House from Hertfordshire, and she invited Watts to continue with them. He particularly enjoyed

Michael Faraday Primary school is situated on the Aylesbury Estate in Walworth . A building at London South Bank University , which houses the institute's electrical engineering departments is named the Faraday Wing, due to its proximity to Faraday's birthplace in Newington Butts . A hall at Loughborough University

2800-399: Is accepted as the basis of all modern theories of electromagnetic phenomena. On Faraday's uses of lines of force , Maxwell wrote that they show Faraday "to have been in reality a mathematician of a very high order – one from whom the mathematicians of the future may derive valuable and fertile methods." The SI unit of capacitance is named in his honour: the farad . Albert Einstein kept

2912-484: Is almost entirely personal I cannot afford to get rich." Faraday died at his house at Hampton Court on 25 August 1867, aged 75. He had some years before turned down an offer of burial in Westminster Abbey upon his death, but he has a memorial plaque there, near Isaac Newton 's tomb. Faraday was interred in the dissenters ' (non- Anglican ) section of Highgate Cemetery . Faraday's earliest chemical work

Faraday was the first to report what later came to be called metallic nanoparticles . In 1847 he discovered that the optical properties of gold colloids differed from those of the corresponding bulk metal. This

3136-705: Is based on an intellectual ladder of discoveries and insights from ancient times to the present. Many mathematical and physical ideas used today found their earliest expression in the work of ancient civilizations, such as the Babylonian astronomers and Egyptian engineers , the Greek philosophers of science and mathematicians such as Thales of Miletus , Euclid in Ptolemaic Egypt , Archimedes of Syracuse and Aristarchus of Samos . Roots also emerged in ancient Asian cultures such as India and China, and particularly

The poem was also featured in the segment on the cartoon programme "Rocky and His Friends" called "Bullwinkle's Corner", in which Bullwinkle Moose recites poetry. In this case, the poem was titled "The Bee", with no author credit. A second example appears in Chapter 10 of Alice's Adventures in Wonderland , the poem " 'Tis the Voice of the Lobster ", which parodies

3360-520: Is called a proposition". Watts' Logic follows the scholastic tradition and divides propositions into universal affirmative, universal negative, particular affirmative, and particular negative. In the third part, Watts discusses reasoning and argumentation , with particular emphasis on the theory of syllogism . This was considered a centrally important part of classical logic . According to Watts, and in keeping with logicians of his day, Watts defined logic as an art (see liberal arts ), as opposed to

3472-720: Is credited by many with introducing hymns to the English churches when his Hymns and Spiritual Songs was first published in 1707. They are extensively used today due to his poetic gifts, but also because he interpreted the Old Testament using knowledge of the New. This set an example for later hymn writers. Isaac Watts explained his methods as follows: “Where the Psalmist describes religion by the fear of God, I have often joined faith and love to it. Where he speaks of pardon of sin through

In 1821, soon after the Danish physicist and chemist Hans Christian Ørsted discovered the phenomenon of electromagnetism , Davy and William Hyde Wollaston tried, but failed, to design an electric motor . Faraday, having discussed

4816-573: The laws of electrolysis . His inventions of electromagnetic rotary devices formed the foundation of electric motor technology, and it was largely due to his efforts that electricity became practical for use in technology. As a chemist, Faraday discovered benzene , investigated the clathrate hydrate of chlorine, invented an early form of the Bunsen burner and the system of oxidation numbers , and popularised terminology such as " anode ", " cathode ", " electrode " and " ion ". Faraday ultimately became

His lectures were joyful and juvenile, he delighted in filling soap bubbles with various gasses (in order to determine whether or not they are magnetic), but the lectures were also deeply philosophical. In his lectures he urged his audiences to consider the mechanics of his experiments: "you know very well that ice floats upon water ... Why does

5936-501: The book comes under one or more of these headings, and this methodical arrangement serves to make the exposition clear. In Watts' Logic, there are notable departures from other works of the time, and some notable innovations. The influence of British empiricism may be seen, especially that of contemporary philosopher and empiricist John Locke . Logic includes several references to Locke and his Essay Concerning Human Understanding , in which he espoused his empiricist views. Watts

One of Watts' best-known poems was an exhortation " Against Idleness and Mischief " in Divine Songs for Children . This was parodied by Lewis Carroll in the poem " How Doth the Little Crocodile ", included in Chapter 2 of Alice's Adventures in Wonderland (1865). His parody

6272-584: The charge resided only on the exterior of a charged conductor, and exterior charge had no influence on anything enclosed within a conductor. This is because the exterior charges redistribute such that the interior fields emanating from them cancel one another. This shielding effect is used in what is now known as a Faraday cage . In January 1836, Faraday had put a wooden frame, 12 ft square, on four glass supports and added paper walls and wire mesh. He then stepped inside and electrified it. When he stepped out of his electrified cage, Faraday had shown that electricity

In Sept 1845 he wrote in his notebook, "I have at last succeeded in illuminating a magnetic curve or line of force and in magnetising a ray of light ". Later on in his life, in 1862, Faraday used a spectroscope to search for a different alteration of light, the change of spectral lines by an applied magnetic field. The equipment available to him was, however, insufficient for

As per the American Institute of Physics , some 20% of new physics Ph.D.s holds jobs in engineering development programs, while 14% turn to computer software and about 11% are in business/education. A majority of physicists employed apply their skills and training to interdisciplinary sectors (e.g. finance ). Job titles for graduate physicists include Agricultural Scientist , Air Traffic Controller , Biophysicist , Computer Programmer , Electrical Engineer , Environmental Analyst , Geophysicist , Medical Physicist , Meteorologist , Oceanographer , Physics Teacher / Professor / Researcher , Research Scientist , Reactor Physicist , Engineering Physicist , Satellite Missions Analyst, Science Writer , Stratigrapher , Software Engineer , Systems Engineer , Microelectronics Engineer , Radar Developer, Technical Consultant, etc. The majority of Physics terminal bachelor's degree holders are employed in

8400-496: The late 18th century: remaining parts of the memorial were rescued at the last minute by a wealthy landowner for installation in his chapel near Liverpool , but it is not known whether the bust survives. Another bust is installed at the nonconformist Dr Williams's Library , in central London. The first public statue stands at Abney Park , where Watts lived for more than 30 years at the manor house, and where he also died. The park later became Abney Park Cemetery , opened in 1840; and

8512-581: The mercies of God, I have added the merits of a Saviour. Where he talks of sacrificing goats and bullocks, I rather mention the sacrifice of Christ, the Lamb of God. When he attends the ark with shouting into Zion, I sing of the ascension of my Saviour into heaven, or His presence in His church on earth. Where he promises abundance of wealth, honour, and long life, I have changed some of these typical blessings for grace, glory, and life eternal, which are brought to light in

8624-519: The opening lines of " The Sluggard ": "'Tis the voice of the sluggard; I heard him complain, / 'You have waked me too soon, I must slumber again.'" The 1884 comic opera Princess Ida includes a punning reference to Watts in Act I. At Princess Ida's women's university, no males are allowed. Her father King Gama says that "She'll scarcely suffer Dr. Watts' 'hymns'". A poem often referred to as "False Greatness" by Joseph Merrick ("The Elephant Man"), which

8736-847: The planning and judging of exhibits for the Great Exhibition of 1851 in Hyde Park , London. He also advised the National Gallery on the cleaning and protection of its art collection, and served on the National Gallery Site Commission in 1857. Education was another of Faraday's areas of service; he lectured on the topic in 1854 at the Royal Institution, and, in 1862, he appeared before a Public Schools Commission to give his views on education in Great Britain. Faraday also weighed in negatively on

8848-543: The preparation of nitrogen trichloride samples, and they both were injured in an explosion of this very sensitive substance. Faraday married Sarah Barnard (1800–1879) on 12 June 1821. They met through their families at the Sandemanian church, and he confessed his faith to the Sandemanian congregation the month after they were married. They had no children. Faraday was a devout Christian; his Sandemanian denomination

8960-401: The principles and suggestions contained therein. During this period, Faraday held discussions with his peers in the City Philosophical Society, where he attended lectures about various scientific topics. He also developed an interest in science, especially in electricity. Faraday was particularly inspired by the book Conversations on Chemistry by Jane Marcet . In 1812, at the age of 20 and at

9072-433: The private sector. Other fields are academia, government and military service, nonprofit entities, labs and teaching. Typical duties of physicists with master's and doctoral degrees working in their domain involve research, observation and analysis, data preparation, instrumentation, design and development of industrial or medical equipment, computing and software development, etc. The highest honor awarded to physicists

9184-406: The problem with the two men, went on to build two devices to produce what he called "electromagnetic rotation". One of these, now known as the homopolar motor , caused a continuous circular motion that was engendered by the circular magnetic force around a wire that extended into a pool of mercury wherein was placed a magnet; the wire would then rotate around the magnet if supplied with current from

9296-406: The public's fascination with table-turning , mesmerism , and seances , and in so doing chastised both the public and the nation's educational system. Before his famous Christmas lectures, Faraday delivered chemistry lectures for the City Philosophical Society from 1816 to 1818 in order to refine the quality of his lectures. Between 1827 and 1860 at the Royal Institution in London, Faraday gave

9408-454: The risk was ignored for over 60 years until the 1913 Senghenydd Colliery Disaster . As a respected scientist in a nation with strong maritime interests, Faraday spent extensive amounts of time on projects such as the construction and operation of lighthouses and protecting the bottoms of ships from corrosion . His workshop still stands at Trinity Buoy Wharf above the Chain and Buoy Store, next to London's only lighthouse where he carried out

9520-455: The scientific community. It would be another half a century before electricity was used in technology, with the West End 's Savoy Theatre , fitted with the incandescent light bulb developed by Sir Joseph Swan , the first public building in the world to be lit by electricity. As recorded by the Royal Institution , "Faraday invented the generator in 1831 but it took nearly 50 years before all

9632-546: The statue of Watts was erected here by public subscription in 1845. It stands in Dr Watts' Walk, in front of the Abney Park Chapel , and was designed by the leading British sculptor, Edward Hodges Baily . A scheme for a commemorative statue on this spot had been promoted in the late 1830s by George Collison , who in 1840 published an engraving as the frontispiece of his book about cemetery design in Europe and America, and at Abney Park in particular. Collison's proposal

9744-405: The technology, including Joseph Swan's incandescent filament light bulbs used here, came into common use". In 1845, Faraday discovered that many materials exhibit a weak repulsion from a magnetic field: an effect he termed diamagnetism . Faraday also discovered that the plane of polarization of linearly polarised light can be rotated by the application of an external magnetic field aligned with

9856-449: The time of Watts, as documented by Prutow. The teachings of 16th-century Reformation leaders such as John Calvin , who translated the Psalms in the vernacular for congregational singing, followed this historic worship practice. Watts was not the first Protestant to promote the singing of hymns; however, his prolific hymn writing helped usher in a new era of English worship as many other poets followed in his path. Watts also introduced

9968-406: The title "Faraday's Electricity", he featured in their World Changers issue along with Charles Darwin , Edward Jenner and Alan Turing . The Faraday Institute for Science and Religion derives its name from the scientist, who saw his faith as integral to his scientific research. The logo of the institute is also based on Faraday's discoveries. It was created in 2006 by a $ 2,000,000 grant from

10080-633: The unity of God and nature pervaded Faraday's life and work." In June 1832, the University of Oxford granted Faraday an honorary Doctor of Civil Law degree. During his lifetime, he was offered a knighthood in recognition for his services to science, which he turned down on religious grounds, believing that it was against the word of the Bible to accumulate riches and pursue worldly reward, and stating that he preferred to remain "plain Mr Faraday to

10192-430: The vapours of liquids possessing a very low boiling point and gave a more solid basis to the concept of molecular aggregation. In 1820 Faraday reported the first synthesis of compounds made from carbon and chlorine, C 2 Cl 6 and CCl 4 , and published his results the following year. Faraday also determined the composition of the chlorine clathrate hydrate , which had been discovered by Humphry Davy in 1810. Faraday

10304-519: Was a force, not an imponderable fluid as was believed at the time. Faraday had a long association with the Royal Institution of Great Britain . He was appointed Assistant Superintendent of the House of the Royal Institution in 1821. He was elected a Fellow of the Royal Society in 1824. In 1825, he became Director of the Laboratory of the Royal Institution. Six years later, in 1833, Faraday became

10416-610: Was a nonconformist and these universities were restricted to Anglicans—as were government positions at the time. He went to the Dissenting Academy at Stoke Newington in 1690. Much of the remainder of his life centred on that village, which is now part of Inner London . Following his education, Watts was called as pastor of a large independent chapel in London, Mark Lane Congregational Chapel, where he helped train preachers, despite his poor health. He held religious opinions that were more nondenominational or ecumenical than

10528-499: Was also the first substance found to be repelled by the poles of a magnet. Faraday invented an early form of what was to become the Bunsen burner , which is still in practical use in science laboratories around the world as a convenient source of heat. Faraday worked extensively in the field of chemistry, discovering chemical substances such as benzene (which he called bicarburet of hydrogen) and liquefying gases such as chlorine. The liquefying of gases helped to establish that gases are

10640-443: Was also widely used as a moral textbook in schools. In Logic , Watts gave an early definition of chemical element , and contrasted "element" with chemical "compound" in clear, modern terms. He also provided an early list of elements then recognized by chemists—five in number—as he understood it. Watts did also, however, note the lack of consensus among chemists. On his death, Isaac Watts' papers were given to Yale University in

10752-584: Was an offshoot of the Church of Scotland . Well after his marriage, he served as deacon and for two terms as an elder in the meeting house of his youth. His church was located at Paul's Alley in the Barbican . This meeting house relocated in 1862 to Barnsbury Grove, Islington ; this North London location was where Faraday served the final two years of his second term as elder prior to his resignation from that post. Biographers have noted that "a strong sense of

10864-453: Was as an assistant to Humphry Davy . Faraday was involved in the study of chlorine ; he discovered two new compounds of chlorine and carbon : hexachloroethane which he made via the chlorination of ethylene and carbon tetrachloride from the decomposition of the former. He also conducted the first rough experiments on the diffusion of gases, a phenomenon that was first pointed out by John Dalton . The physical importance of this phenomenon

10976-731: Was based on the poetry of the Bible: the Psalms . According to LeFebvre, Psalms had been sung by God's people from the time of King David, who with a large staff over many years assembled the complete book of Psalms in a form appropriate for singing (by the Levites, during Temple sacrifices at the time). The practice of singing Psalms in worship was continued by Biblical command in the New Testament Church from its beginnings in Acts through

11088-512: Was born in the autumn of the following year, the third of four children. The young Michael Faraday, having only the most basic school education, had to educate himself . At the age of 14, he became an apprentice to George Riebau , a local bookbinder and bookseller in Blandford Street. During his seven-year apprenticeship Faraday read many books, including Isaac Watts 's The Improvement of the Mind , and he enthusiastically implemented

11200-540: Was born on 22 September 1791 in Newington Butts , Surrey , which is now part of the London Borough of Southwark . His family was not well off. His father, James, was a member of the Glasite sect of Christianity. James Faraday moved his wife, Margaret (née Hastwell), and two children to London during the winter of 1790 from Outhgill in Westmorland , where he had been an apprentice to the village blacksmith. Michael

11312-413: Was careful to distinguish between judgements and propositions , unlike some other logic authors. According to Watts, judgement is "to compare... ideas together, and to join them by affirmation , or disjoin then by negation , according as we find them to agree or disagree". He continues, "when mere ideas are joined in the mind without words, it is rather called a judgement; but when clothed with words it

11424-746: Was coined by William Whewell (also the originator of the term "scientist") in his 1840 book The Philosophy of the Inductive Sciences . A standard undergraduate physics curriculum consists of classical mechanics , electricity and magnetism , non-relativistic quantum mechanics , optics , statistical mechanics and thermodynamics , and laboratory experience. Physics students also need training in mathematics ( calculus , differential equations , linear algebra , complex analysis , etc.), and in computer science . Any physics-oriented career position requires at least an undergraduate degree in physics or applied physics, while career options widen with

11536-492: Was common for a nonconformist Congregationalist. He had a greater interest in promoting education and scholarship than preaching for any particular sect. Watts took work as a private tutor and lived with the nonconformist Hartopp family at Fleetwood House on Church Street in Stoke Newington . Through them, he became acquainted with their immediate neighbours Sir Thomas Abney and Lady Mary . He eventually lived for

11648-435: Was immediate, kind, and favourable. In 1813, when Davy damaged his eyesight in an accident with nitrogen trichloride , he decided to employ Faraday as an assistant. Coincidentally one of the Royal Institution's assistants, John Payne, was sacked and Sir Humphry Davy had been asked to find a replacement; thus he appointed Faraday as Chemical Assistant at the Royal Institution on 1 March 1813. Very soon, Davy entrusted Faraday with

11760-570: Was influential amongst nonconformist independents and religious revivalists of the 18th century, such as Philip Doddridge , who dedicated his best-known work to Watts. Sacred music scholars Stephen Marini, Denny Prutow and Michael LeFebvre describe the ways in which Watts contributed to English hymnody and the previous tradition of the Church. Watts led the change in practice by including new poetry for "original songs of Christian experience" to be used in worship, according to Marini. The older tradition

11872-434: Was more fully revealed by Thomas Graham and Joseph Loschmidt . Faraday succeeded in liquefying several gases, investigated the alloys of steel, and produced several new kinds of glass intended for optical purposes. A specimen of one of these heavy glasses subsequently became historically important; when the glass was placed in a magnetic field Faraday determined the rotation of the plane of polarisation of light. This specimen

11984-506: Was named after Faraday in 1960. Near the entrance to its dining hall is a bronze casting, which depicts the symbol of an electrical transformer , and inside there hangs a portrait, both in Faraday's honour. An eight-storey building at the University of Edinburgh 's science & engineering campus is named for Faraday, as is a recently built hall of accommodation at Brunel University , the main engineering building at Swansea University , and

12096-643: Was never commissioned, and Baily's design was adopted instead. A later, rather similar statue was also funded by public subscription and erected in a new Victorian public park named after Watts in Southampton, the city of his birth. In the mid-nineteenth century, the Congregational Dr Watts Memorial Hall was built in Southampton and also named after him. It was lost to redevelopment after the Second World War , but

12208-461: Was one of the most influential scientists in history. It was by his research on the magnetic field around a conductor carrying a direct current that Faraday established the concept of the electromagnetic field in physics. Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena. He similarly discovered the principles of electromagnetic induction, diamagnetism, and

12320-436: Was probably the first reported observation of the effects of quantum size, and might be considered to be the birth of nanoscience . Faraday is best known for his work on electricity and magnetism. His first recorded experiment was the construction of a voltaic pile with seven British halfpenny coins, stacked together with seven discs of sheet zinc, and six pieces of paper moistened with salt water. With this pile he passed

12432-663: Was the principal topic of the tenth episode, titled " The Electric Boy ", of the 2014 American science documentary series, Cosmos: A Spacetime Odyssey , which was broadcast on Fox and the National Geographic Channel . The writer Aldous Huxley wrote about Faraday in an essay entitled, A Night in Pietramala : "He is always the natural philosopher. To discover truth is his sole aim and interest ... even if I could be Shakespeare, I think I should still choose to be Faraday." Calling Faraday her "hero", in

12544-446: Was used in writing or "signature block" by Merrick, starting "Tis true, my form is something odd/but blaming me, is blaming God..." is often (incorrectly) quoted or cited as a work by Isaac Watts. In fact only the last few sentences were penned by Watts ("False Greatness", book II-Horae lyricae 1743) starting "Mylo, forbear to call him bless'd/That only boasts a large estate..." Watts' hymns include: Many of Watts' hymns are included in
