If God has made the world a perfect mechanism, He has at least conceded so much to our imperfect intellect that in order to predict little parts of it, we need not solve innumerable differential equations, but can use dice with fair success.

The fifth day of the year; five is the number of Platonic Solids. Five is also the smallest number of queens needed to attack every square on a standard chess board. (can you demonstrate such a board ?)
The sum of the first five integers raised to their own power, is prime, (and so is the sum of the first six)
One of math's perplexing mysteries. A sphere in five dimensional space has a larger volume ( ) than in any other dimension for a unit radius. From two dimensions up to five the volume increases, then decreases forever after.
In 1845, Gabriel Lame proved a remarkable theorem involving the number 5. "The number of steps (i.e., divisions) in an application of the Euclidean algorithm never exceeds 5 times the number of (decimal) digits in the lesser." Donald Knuth (1969) extended this to show that, this was related to the Fibonacci numbers (and ).
and from Jim Wilder : 1084 is the smallest integer whose spelling, one thousand eighty-four, contains the 5 vowels (a, e, i, o, u) in order.

1665 The first volume of the Journal des Savants appeared in Paris. The Journal des sçavans (later renamed Journal des savants), founded by Denis de Sallo, was the earliest academic journal published in Europe, that from the beginning also carried a proportion of material that would not now be considered scientific, such as obituaries of famous men, church history, and legal reports. The first edition appeared as a twelve page quarto pamphlet on Monday, 5 January 1665. This was shortly before the first appearance of the Philosophical Transactions of the Royal Society, on 6 March 1665. *Wik
1723 (Jan 5,1723 - ?) Nicole-Reine Étable (de la Briere ) Lepaute was born in Paris and began to take an interest in mathematics and astronomy in around the time she married her husband Jean-André Lepaute the royal clock maker. Together with her husband she designed and constructed an astronomical clock, which was presented to the French Academy of Science in 1753. She, her husband and Lalande worked on a book entitled Traite d’horologerie(Treatise on Clockmaking) that was published under her husbands name in 1755. Although she was not mentioned as author Lalande honoured her contribution as follows:
“Madame Lepaute computed for this book a table of numbers of oscillations for pendulums of different lengths, or the lengths for each given number of vibrations, from that of 18 lignes, that does 18000 vibrations per hour, up to that of 3000 leagues.”
Following her work with Lalande on Comet Halley, she again collaborated with him on the ephemeris for the 1761 Transit of Venus. She also collaborated with Lalande for fifteen years on the calculations for the Connaissance des temps. In 1762 she calculated the exact time for a solar eclipse that occurred on 1 April 1764. She also wrote an article on the eclipse with an eclipse map. She produced star catalogues and calculated an ephemeris of the sun, moon and the planets from 1774 to 1784. Although childless she adopted and trained he husband nephew, Joseph Lepaute Dagelet (175116788) in astronomy and mathematics. He went on to become professor of mathematics at the French Military School and later deputy astronomer at the French Academy of Science, where he had a distinguished career. A comet and a crater on the moon are named in her honour. <br>This post taken entirely from a longer article by Thony Christie.

1874 In a letter to Dedekind, Cantor asks if the points in a square can be put in one-to-one correspondence with those on a line. “Methinks that answering this question would be no easy job, despite the fact that the answer seems so clearly to be ‘no’ that proof appears almost unnecessary.” It was three years before Cantor could prove the answer was “yes”. *VFR
In 1892, the first successful auroral photograph was made by the German physicist Martin Brendel. Although it was limited to a blurred, low-contrast picture, it did convey some sense of the shape of the aurora. The task was not easy because the auroral light itself was generally feeble and flickering while photographic materials of the time required a long exposure, and was little sensitive to the deep reds in the aurora. One of his photographs, taken on 1 Feb 1892 was published in the Century Magazine of Oct 1897. Brendel had traveled to Alten Fiord, Lapland, to spend several months studying auroral displays and magnetic disturbances. The first colour pictures were not taken until about 1950, and Life magazine published colour aurora photographs in 1953.*TIS

1900 Minkowski responds to Hilbert who had asked his opinion about several potential topics for Hilbert's address at the Second International Conference of Mathematicians in Paris, in the summer. Minkowski responds that, "Most alluring would be the attempt at a look into the future and a listing of the problems on which mathematicians should try themselves during the coming century. With such a lecture you could have people talking about your lecture decades later." *Reid, Hilbert, pg 69
1902 In a letter to his mother, Earnest Rutherford writes, “I have to keep going, as there are always people on my track.

1962 The first reference to Simula in writing is made. This early object-oriented language was written by Kristen Nygaard and Ole-John Dahl of the Norwegian Computing Center in Oslo. Simula grouped data and instructions into blocks called objects, each representing one facet of a system intended for simulation. *CHM
1974 The famous grasshopper weather vane atop Faneuil Hall in Boston was removed by thieves, but later recovered. When a weather vane was fashioned for this famous trading hall of colonial Boston, the grasshopper was chosen as it appears on the crest of Sir Thomas Gresham, founder of England’s Royal Exchange.

1909 Stephen Cole Kleene (5 Jan 1909; 25 Jan 1994) American mathematician and logician whose research was on the theory of algorithms and recursive functions. He developed the field of recursion theory with Church, Gödel, Turing and others. He contributed to mathematical Intuitionism which had been founded by Brouwer. His work on recursion theory helped to provide the foundations of theoretical computer science. By providing methods of determining which problems are soluble, Kleene's work led to the study of which functions can be computed. *TIS
1943 George Washington Carver (1861?, 5 Jan 1943)American agricultural chemist, agronomist, and experimenter who helped revolutionize the agricultural economy of the South. Carver demonstrated to farmers how fertility could be restored to their land by diversification, especially by planting peanuts and sweet potatoes, to replenish soil impoverished by the regular growth of cotton and tobacco. He showed that peanuts contained several different kinds of oil, and peanut butter was another of his innovations. In all he is reported to have developed over 300 new products from peanuts and over 100 from sweet potatoes. For most of his career he taught and conducted research at the Tuskegee Institute, Alabama where he stayed despite lucrative offers to work for such magnates as Henry Ford and Thomas Edison. *TIS

BIRTHS
1723 Nicole-Reine Lepaute (5 Jan 1723 in Paris, France - 6 Dec 1788 in Saint-Cloud, France) was a French noblewoman who helped Lalande with astronomical calculations. In June 1757 Lalande decided that he would like to attempt to calculate a precise date for the return of Halley's comet. It was known to have been seen in 1305, 1380, 1456, 1531, 1607 and 1682 and Halley, taking into account perturbations to the orbit caused by the gravitational effects of Jupiter, had predicted that the comet would return reaching perihelion in December 1758. However the only way to get a more accurate prediction of its date of return was to calculate the perturbations to the orbit caused by the gravitational effects of both Jupiter and Saturn. Lalande approached Alexis Clairaut for help and Clairaut provided a basic programme of work requiring an extraordinary amount of computation. Lalande then asked Nicole-Reine Lepaute to assist him in the computations. Lalande wrote, "During six months we calculated from morning to night, sometimes even at meals. ... The assistance of Mme Lepaute was such that, without her I should never have been able to undertake the enormous labour, in which it was necessary to calculate the distance of each of the two planets Jupiter and Saturn from the comet, separately for each successive degree for 150 years. *SAU1838 Camille Jordan (5 Jan 1838; 20 Jan 1922) French mathematician and engineer who prepared a foundation for group theory and built on the prior work of Évariste Galois (died 1832).
