1760réf. 6004American or British After 1760. Very Good/Manuscript 18th-century game or puzzle which allows whoever knows the key to accurately guess anyone's age or chosen number in a "pick-a-number" scenario. We won't divulge the secret--but it has to do with binomial number systems--and it works! Similar magic age tables persist to the present day in a somewhat different form. . 1 leaf 200 x 323mm; watermark of crowned lion with scepter and fascia of arrows very like Churchill #88 which he identifies as English colonial dated 1762. Seven columns of numbers with brief explanation on verso. Folds some beginning to split. unknown books
réf. 14231Brilliant mathematician who made important contributions to the study of algebra and logic. Autograph letter signed. 4 pages. 7.25" x 4.5" inches. No place. December 6th 1857. To Miss Anna Blackwell. An interesting letter in which Augustus De Morgan talks about and ridicules some recent designs for flying machines and speculates on whether heavier than air manned flight will ever be achieved. He illustrates the letter with his own amusing drawings. "I have read your MSS according to promise and regret to say that I have no heavenly hopes excited by Monsieur Petin. It seems to me that his mechanics are as opposed to the common notions on which the Menai tunnel was built and the locomotives made to go through it as his mathematics to the way in which Euclid and Newton thought. His ideas about a point multiplied by itself producing a line etc are purely elementary misconceptions of some of the language used by mathematicians - and show him to be not even in the outer court of that temple. His mechanics seem to me as strange. I should take issue on the question of the machine blowing itself up in the air by directing a current on an oblique sail or wing. According to M. Petin if a man could but blow hard enough he could blow himself up into the air by holding out a looking-glass obliquely and blowing against it. inserted here is an amusing drawing captioned: M. Petin inventor of the pneumatic ascent into heaven - Grief of the Devil thereat - and wonder of the heavenly host. Any person who was but commonly acquainted with mechanics would have seen so much contradiction to all that is known in this ascent - and in the machine blowing itself forward any way - that he would have held himself bound to do something of the kind first on a small scale. If he would only have made a boat with a blowing machine on board blow itself forward in a small model he would have justified some attention being paid to him. I think his upward motion would turn to simple revolution as every upward motion does in France. He would blow his machine round and round - and the passengers would try the floor and ceiling alternatively - a plusiers reprises. I think that if you were to recast all the phrases in which you express some agreement with M. Petin and make it merely the expression of his opinions - you would do well to publish it - for it is very amusing and instructive - I send you an account of a Petin - and I have known a great many. But I think he will not overcome the difficulties. If he do it will be without knowing them. There are plenty of points on which we know nothing about the mechanics of the air but there are some which we do know or think we know and which until M. Petin actually unconvinces us by experiment we shall remain of opinion that his contrivance is a fight with the presence of the power of the air - in which he must be beaten. I think you have just hit the mark when you say that flying in the air will be done by something as distinct from any action as . . . of it now as the railway is distinct from the seven league boats - I have no doubt that something of this kind will be done at last." Augustus de Morgan was a highly respected and important mathematician of his time. He was a friend of Charles Babbage inventor of the analytical machine forerunner of the modern computer and was tutor to Ada Lovelace the daughter of the poet Lord Byron who supposedly wrote the first programme for Babbage's machine. He coined the terms 'mathematical induction' and 'double-algebra' and formulated De Morgan's Laws the mathematical rules that are named after him. The work of Augustus De Morgan led to the development of the theory of relations and the rise of modern symbolic or mathematical logic. He introduced and defined the term mathematical induction to describe the process that until then had been used with little clarity in mathematical proofs. He was known as a witty correspondent and this is amply demonstrated in this fine autograph letter to Miss Blackwell. His correspondent Anna Blackwell 1816-1900 was the elder sister of Elizabeth Blackwell the first woman to gain a medical degree in America and the first woman to be registered in Britain as a medical practitioner. Anna Blackwell had a career as a poet translator and journalist but nurtured an interest in science and was a member of the Association Scientifique de France. Old folds and slight mounting traces to left margin of first leaf else fine. Provenance: From a 19th century album composed by the Blyth family. Edward Blyth a London solicitor was a friend and advisor to Elizabeth Blackwell and her family. unknown books
réf. 14230British mathematician and astronomer taking the title of Astronomer Royal from 1835 to 1881. Airy is known for establishing Greenwich as the location of the prime meridian. Autograph letter Signed. 1 page. 6.25" x 3.75" inches. Royal Observatory Greenwich. March 27th 1851. To the engineer Charles Manby. "I am much obliged by your note regarding the presenting of the Paper & Discussion on the Exhibition Building. It will enable me to remove some misunderstanding." In addition to his considerable achievements as a mathematician and astronomer George Biddell Airy was also an accomplished engineer and pioneered research into stress fractures in girder beam construction. He was the expert who advised on the effect of wind speed and stress during the construction of the Tay Bridge. The "Exhibition Building" referred to in this letter is the Crystal Palace erected for the Great Exhibition of 1851. Airy had been consulted regarding stress in the ironwork and had given the opinion that Paxton's design was susceptible to stress caused by the resonance of the sound of the many people who would pass through the building. There was widespread disagreement over this and in this letter Airy is evidently thanking Manby for the opportunity to clarify his views at a meeting. Letter is trimmed and with mounting traces to verso. All else very good. unknown books
réf. 13906This 'Cyphering Book' is the handwritten mathematical 18th century workbook of David Tolbut dated 1790. Rockport ME. 64 pages. 12"x7.5". A remarkable well-executed and organized collection of math problems and instruction. Major headings include all as written: "Of Cloth Measure; Of Land Measure; Liquid Measure; Dry Measure; Of Time; The Golden Rule; The Double Rule of Three; Measuring; Single Fellowship; Double Fellowship; Practice; Interest; Compound Interest; Allegation; Loss and Gain; Equation of Payment; Barter; Brokerage; Invers Proportion; Single Position; Double Position; Exchange; Fare and Frett." Filled with multiple formulas showing a remarkable example of how mathematics were taught in the era of the American Revolution. The mathematical formulas follow the trend of this time period in that they are highly practical. Even abstract concepts like barter are expressed as an equation. Each lesson includes multiple examples and equations. Every page is completely filled most including multiple calculations. The condition shows light tidemarks some ink see through light even toning and soiling and some slight splitting. Otherwise in very good condition and an excellent example of mathematics use in the 18th century. unknown books
réf. 14232British mathematician. Autograph letter signed. 2 pages. University College London. October 29th 1850. To Wiliam Parker Hammond Junior. 7" x 4.5" inches. "In reply to your request for an autograph I send you one on the other side and remain your obedient servant" etc. Augustus De Morgan was a brilliant mathematician who made important contributions to the study of algebra and logic. He was a friend of Charles Babbage inventor of the Analytical Machine forerunner of the modern computer and tutor to Ada Lovelace daughter of the poet Lord Byron who is credited with writing the first computer programme. Augustus De Morgan coined the terms 'mathematical induction' and 'double-algebra' and formulated De Morgan's Laws the mathematical rules named after him. The work of De Morgan led to the development of the theory of relations and the rise of modern symbolic or mathematical logic. He introduced and defined the term' mathematical induction' to describe the process that until then had been used with little clarity in mathematical proofs. De Morgan was also the first to propose and use the oblique stroke in the printing of fractions. The two pages of the letter have been separated so as to display both in an album but without any loss to either leaf. There are mounting traces to the blank versos of both and some old staining from the paste that was originally used to affix them in an album. All else very good. unknown books
