IN: Alexander Bell was born in Edinburgh, Scotland, on March 3, 1847. The family home was at 16 South Charlotte Street, and has a stone inscription marking it as Alexander Graham Bell's birthplace. He had two brothers: Melville James Bell (1845-70) and Edward Charles Bell (1848-67), both of whom would die of tuberculosis. His father was Professor Alexander Melville Bell, a phonetician, and his mother was Eliza Grace (nee Symonds).

Although Alexander Graham Bell is most often associated with the invention of the telephone, his interests were extremely varied. According to one of his biographers, Charlotte Gray, Bell's work ranged "unfettered across the scientific landscape" and he often went to bed voraciously reading the Encyclopaedia Britannica, scouring it for new areas of interest. The range of Bell's inventive genius is represented only in part by the 18 patents granted in his name alone and the 12 he shared with his collaborators. These included 14 for the telephone and telegraph, four for the photophone, one for the phonograph, five for aerial vehicles, four for "hydroairplanes", and two for selenium cells. Bell's inventions spanned a wide range of interests and included a metal jacket to assist in breathing, the audiometer to detect minor hearing problems, a device to locate icebergs, investigations on how to separate salt from seawater, and work on finding alternative fuels.  Bell worked extensively in medical research and invented techniques for teaching speech to the deaf. During his Volta Laboratory period, Bell and his associates considered impressing a magnetic field on a record as a means of reproducing sound. Although the trio briefly experimented with the concept, they could not develop a workable prototype. They abandoned the idea, never realizing they had glimpsed a basic principle which would one day find its application in the tape recorder, the hard disc and floppy disc drive, and other magnetic media.  Bell's own home used a primitive form of air conditioning, in which fans blew currents of air across great blocks of ice. He also anticipated modern concerns with fuel shortages and industrial pollution. Methane gas, he reasoned, could be produced from the waste of farms and factories. At his Canadian estate in Nova Scotia, he experimented with composting toilets and devices to capture water from the atmosphere. In a magazine interview published shortly before his death, he reflected on the possibility of using solar panels to heat houses.

IN: Friedrich Ludwig Gottlob Frege (; German: ['gotlo:p 'fre:g@]; 8 November 1848 - 26 July 1925) was a German philosopher, logician, and mathematician. He is understood by many to be the father of analytic philosophy, concentrating on the philosophy of language and mathematics. Though largely ignored during his lifetime, Giuseppe Peano (1858-1932) and Bertrand Russell (1872-1970) introduced his work to later generations of logicians and philosophers.

Frege's 1892 paper, "On Sense and Reference" ("Uber Sinn und Bedeutung"), introduced his influential distinction between sense ("Sinn") and reference ("Bedeutung", which has also been translated as "meaning", or "denotation"). While conventional accounts of meaning took expressions to have just one feature (reference), Frege introduced the view that expressions have two different aspects of significance: their sense and their reference.  Reference, (or, "Bedeutung") applied to proper names, where a given expression (say the expression "Tom") simply refers to the entity bearing the name (the person named Tom). Frege also held that propositions had a referential relationship with their truth-value (in other words, a statement "refers" to the truth-value it takes). By contrast, the sense (or "Sinn") associated with a complete sentence is the thought it expresses. The sense of an expression is said to be the "mode of presentation" of the item referred to, and there can be multiple modes of representation for the same referent.  The distinction can be illustrated thus: In their ordinary uses, the name "Charles Philip Arthur George Mountbatten-Windsor", which for logical purposes is an unanalyzable whole, and the functional expression "the Prince of Wales", which contains the significant parts "the prince of x" and "Wales", have the same reference, namely, the person best known as Prince Charles. But the sense of the word "Wales" is a part of the sense of the latter expression, but no part of the sense of the "full name" of Prince Charles.  These distinctions were disputed by Bertrand Russell, especially in his paper "On Denoting"; the controversy has continued into the present, fueled especially by Saul Kripke's famous lectures "Naming and Necessity".

did he have a theory regarding the two?

IN: Sydney Francis Barnes (19 April 1873 - 26 December 1967) was an English professional cricketer who is generally regarded as one of the greatest ever bowlers. He was right-handed and bowled at a pace that varied from medium to fast-medium with the ability to make the ball both swing and break from off or leg. He is the quickest bowler to achieve 150 Test wickets in history. Barnes was unusual in that, despite a very long career as a top-class player, he spent little more than two seasons in first-class cricket, representing Warwickshire and Lancashire.

Barnes was 41 when the First World War broke out and so too old for military service. From 1915 to 1923, he played exclusively for Saltaire in the Bradford League, taking 904 wickets at an average of 5.26. He took a hundred wickets in a season five times, a rare feat in the Bradford League's history. From 1924 to 1930, he played for Castleton Moor and Rochdale in the Central Lancashire League. He was with Rawtenstall in the Lancashire League from 1931 to 1933. Then, aged 61, he returned to the Bradford League to play for Keighley in 1934, which was his final season in league cricket.  Barnes declined the opportunity to join the tour to Australia in 1920-21, when he was 47 years old. He had wanted to bring his family with him, but it became clear that he would have to pay their traveling expenses. He was not selected by England nor did he seek selection by the Players after the First World War. He did not play first-class cricket again until 1927 when he was 54 years old. From then until 1930, he made nine appearances for Wales.  Barnes took 49 wickets for Wales in 1928, including seven for 51 and five for 67 in an eight wicket win over the touring West Indians. He also made two first-class appearances for the Minor Counties in 1929 and took eight for 41 in a drawn game against the South Africans at Stoke-on-Trent. Barnes' final first-class appearance was for Wales against Marylebone Cricket Club (MCC) at Lord's in 1930.  Barnes made 177 appearances for Staffordshire in the Minor Counties Championship between 1904 and 1935. This was in two parts: 1904 to 1914; and 1924 to 1935. His career record for Staffordshire was 1,432 wickets at an average of 8.03.
