The Rhind Mathematical Papyrus, [1] [2] an ancient Egyptian mathematical work, includes a mathematical table for converting rational numbers of the form 2/n into Egyptian fractions (sums of distinct unit fractions), the form the Egyptians used to write fractional numbers. The text describes the representation of 50 rational numbers.
It was circulated by Franklin in manuscript to his circle of friends, but in 1755 it was published as an addendum in a Boston pamphlet on another subject. [2] It was reissued ten times during the next 15 years. [3] The essay examines population growth and its limits. Writing as, at the time, a loyal subject of the British Crown, Franklin argues ...
The 'Canones' are a translation of a diagram from the Toledan Tables by Gerardus Cremonensis. [1] The Toledan Tables, or Tables of Toledo, were astronomical tables which were used to predict the movements of the Sun, Moon and planets relative to the fixed stars. They were a collection of mathematic tables that describe different aspects of the ...
The Table can be found in §§13–16 of the Harleian recension of the Historia, [31] §7 of the Vatican recension, [32] ch. 13 of the Sawley recension [33] and §9 of the Chartres manuscript. [34] In the manuscript Harley 3859 copied around 1100, [ 35 ] which includes the Table, the Historia is interpolated by a 10th-century set of Welsh ...
The Franklin graph can be embedded in the Klein bottle so that it forms a map requiring six colors, showing that six colors are sometimes necessary in this case. This embedding is the Petrie dual of its embedding in the projective plane shown below. It is Hamiltonian and has chromatic number 2, chromatic index 3, radius 3, diameter 3 and girth 4.
Philip Franklin (October 5, 1898 – January 27, 1965) was an American mathematician and professor whose work was primarily focused in analysis. Dr. Franklin received a B.S. in 1918 from City College of New York (who later awarded him its Townsend Harris Medal for the alumnus who achieved notable postgraduate distinction).
Van Doren signed a deal with Viking and received an advance of $3,000 to complete his biography on Benjamin Franklin. [2] Van Doren travelled up and down New England visiting various institutions that housed Franklin's papers to research the book, including the archives at the American Philosophical Society, University of Philadelphia, along with Harvard and Yale University among others.
