Mathematician Ramanujan's house. A dream come true. Coolkarni was visibly impressed and thrilled. This is in Sarangapani sannithi street, Kumbakonam. Ramanujan sat in this platfarm and worked on many of his theorems. This is the only house that is unchanged for the past 100 years or so. Otherwise this legendary street is full of multi storeyed ugly buildings. Its hard to believe that such a derogation can happen to aesthetical senses in the span of just 100 years.
William Oughtred (5 March 1574 – 30 June 1660) was an English mathematician.
After John Napier invented logarithms, and Edmund Gunter created the logarithmic scales (lines, or rules) upon which slide rules are based, it was Oughtred who first used two such scales sliding by one another to perform direct multiplication and division; and he is credited as the inventor of the slide rule in 1622. Oughtred also introduced the "×" symbol for multiplication as well as the abbreviations "sin" and "cos" for the sine and cosine functions.
Oughtred was born at Eton in Buckinghamshire (now part of Berkshire), and educated there and at King's College, Cambridge, of which he became fellow.[2] Being admitted to holy orders, he left the University of Cambridge about 1603, for a living at Shalford; he was presented in 1610 to the rectory of Albury, near Guildford in Surrey, where he settled. About 1628 he was appointed by the Earl of Arundel to instruct his son in mathematics.
He corresponded with some of the most eminent scholars of his time, including William Alabaster, Sir Charles Cavendish, and William Gascoigne.[3][4] He kept up regular contacts with Gresham College, where he knew Henry Briggs and Gunter.[5]
He offered free mathematical tuition to pupils, who included Richard Delamain, and Jonas Moore, making him an influential teacher of a generation of mathematicians. Seth Ward resided with Oughtred for six months to learn contemporary mathematics, and the physician Charles Scarburgh also stayed at Albury; John Wallis, and Christopher Wren corresponded with him.[6] Another Albury pupil was Robert Wood, who helped him get the Clavis through the press.[7]
The invention of the slide rule involved Oughtred in a priority dispute with Delamain. They also disagreed on pedagogy in mathematics, with Oughtred arguing that theory should precede practice.[8][9]
He remained rector until his death in 1660, a month after the restoration of Charles II.
Oughtred had an interest in alchemy and astrology.[11] The testimony for his occult activities is quite slender, but there has been an accretion to his reputation based on his contemporaries.
According to John Aubrey, he was not entirely sceptical about astrology. William Lilly, an eminent astrologer, claimed in his autobiography to have intervened on behalf of Oughtred to prevent his ejection by Parliament in 1646.[12][13] In fact Oughtred was protected at this time by Bulstrode Whitelocke.[14]
Elias Ashmole was (according to Aubrey) a neighbour in Surrey, though Ashmole's estates acquired by marriage were over the county line in Berkshire; and Oughtred's name has been mentioned in purported histories of early freemasonry, a suggestion that Oughtred was present at Ashmole's 1646 initiation going back to Thomas De Quincey.[15][16] It was used by George Wharton in publishing The Cabal of the Twelve Houses astrological by Morinus (Jean-Baptiste Morin) in 1659.
He expressed millenarian views to John Evelyn, as recorded in Evelyn's diary entry for 28 August, 1655.

The first VI. books in a compendious form contracted and demonstrated. By Captain Thomas Rudd. Whereunto is added, the mathematicall preface of Mr. John Dee.
The scarce second English edition of Euclid's Elements, and the First Edition of Thomas Rudd's English version of Euclid (preceded only by the Billingsley version published in folio in 1570) and contains the celebrated "Mathematical Preface" by John Dee that first appeared in the 1570 Billingsley edition.
Captain Thomas Rudd (1583c.- 1656) was an English military engineer and mathematician.
John Dee (1527-1608) was an English mathematician and considered one of the most educated men of his age, lecturing on the geometry of Euclid at the University of Paris.

This image shows the title page of the book. This book is one of two copies held within the University of Glasgow Special Collections. The above copy has the most amount of annotation.
The annotation clearly bears early University press marks on the front flyleaf: annotation confirm that the book belonged to the Glasgow University Librar, for example an inscription by William Dunlop (1654-1700) who was Principal of Glasgow University from 1690 to 1700 can also be seen at the top right side of the page confirming it was purchased for the University in 1691. The text is printed in red and black and contains wooden vignette.

To help us understand Prime numbers better we can think of them as an accumulative sequence which evolves, rather than a fixed pattern which just appeared for no reason. By separating out the sequence at each stage we can better understand how the sequence develops. To do this we look at each Prime number and their subsequent multiples in turn. Looking first at multiples of 2 we see a binary pattern emerge which rules out all even numbers. This is why Prime numbers are all odd numbers after the number 2. At this stage the repeat cycle is 2. When we move on to multiples of 3 and combine these with the multiples of 2 the pattern changes from a simple binary pattern to the more complex pattern of P-P - - - P-P - - -. The repeat cycle is now 2x3=6. Although it is tempting to get excited and think we have stumbled across something which mathematicians across the ages have missed, this is more a set pattern of Composite numbers which also captures Primes in the process. To rule out any Composite numbers from this sequence we have to then look at the next Prime number 5. The repeat cycle is now 2x3x5=30. The more Prime numbers we check the longer the repeat cycle and the more accurate our sieve becomes. The early pattern of Prime numbers soon becomes disrupted as you look at larger numbers. However, the patterns established early on keep reappearing throughout the Prime sequence.
The repeat cycle increases by multiples of Prime numbers, or Primorial, starting with 2, then 2x3=6, then 6x5=30, then 30x7=210, then 210x11=2,310 and so on. We quickly find that we are dealing with repeat cycles in their millions and billions.
