1729 is the natural number following 1728 and preceding 1730. It is known as the Hardy-Ramanujan number, after an anecdote of the British mathematician G. H. Hardy when he visited Indian mathematician Srinivasa Ramanujan in hospital. He related their conversation:
I remember once going to see him when he was ill at Putney. I had ridden in taxi cab number 1729 and remarked that the number seemed to me rather a dull one, and that I hoped it was not an unfavourable omen. "No," he replied, "it is a very interesting number; it is the smallest number expressible as the sum of two cubes in two different ways."
The two different ways are:
1729 = 13 + 123 = 93 + 103The quotation is sometimes expressed using the term "positive cubes", since allowing negative perfect cubes (the cube of a negative integer) gives the smallest solution as 91 (which is a divisor of 1729):
91 = 63 + (−5)3 = 43 + 33Numbers that are the smallest number that can be expressed as the sum of two cubes in n distinct ways have been dubbed "taxicab numbers". The number was also found in one of Ramanujan's notebooks dated years before the incident, and was noted by Frénicle de Bessy in 1657.
The same expression defines 1729 as the first in the sequence of "Fermat near misses" (sequence A050794 in the OEIS) defined, in reference to Fermat's Last Theorem, as numbers of the form 1 + z3 which are also expressible as the sum of two other cubes.1729 English cricket season
1729 was the 33rd English cricket season since the earliest recorded eleven-aside match was played. Details have survived of six matches, the earliest known innings victory is believed to have happened and the earliest known surviving cricket bat dates from the season.1729 in Canada

The Comet of 1729, also known as C/1729 P1 or Comet Sarabat, was a non-periodic comet with an absolute magnitude of −3, the brightest ever observed for a comet; it is therefore considered to be potentially the largest comet ever seen.List of Acts of the Parliament of Great Britain, 1720–1739
This is an incomplete list of Acts of the Parliament of Great Britain for the years 1720–1739. For Acts passed up until 1707 see List of Acts of the Parliament of England and List of Acts of the Parliament of Scotland. See also the List of Acts of the Parliament of Ireland to 1700 and the List of Acts of the Parliament of Ireland, 1701–1800.
For Acts passed from 1801 onwards see List of Acts of the Parliament of the United Kingdom. For Acts of the devolved parliaments and assemblies in the United Kingdom, see the List of Acts of the Scottish Parliament from 1999, the List of Acts of the Northern Ireland Assembly, and the List of Acts and Measures of the National Assembly for Wales; see also the List of Acts of the Parliament of Northern Ireland.
The number shown after each Act's title is its chapter number. Acts are cited using this number, preceded by the year(s) of the reign during which the relevant parliamentary session was held; thus the Union with Ireland Act 1800 is cited as "39 & 40 Geo. 3 c. 67", meaning the 67th Act passed during the session that started in the 39th year of the reign of George III and which finished in the 40th year of that reign. Note that the modern convention is to use Arabic numerals in citations (thus "41 Geo. 3" rather than "41 Geo. III"). Note also that Acts of the last session of the Parliament of Great Britain and the first session of the Parliament of the United Kingdom are both cited as "41 Geo. 3".
Acts passed by the Parliament of Great Britain did not have a short title; however, some of these Acts have subsequently been given a short title by Acts of the Parliament of the United Kingdom (such as the Short Titles Act 1896).
Before the Acts of Parliament (Commencement) Act 1793 came into force on 8 April 1793, Acts passed by the Parliament of Great Britain were deemed to have come into effect on the first day of the session in which they were passed. Because of this, the years given in the list below may in fact be the year before a particular Act was passed.Louis, Dauphin of France (son of Louis XV)
Louis, Dauphin of France (4 September 1729 – 20 December 1765) was the elder and only son of King Louis XV of France and his wife, Queen Marie Leszczyńska to survive to adulthood. He had a younger brother, Philippe, who died as a toddler. As a son of the king, Louis was a fils de France. As heir apparent, he became Dauphin of France. However, he died before ascending to the throne. Three of his sons became kings of France: Louis XVI (reign: 1774–1792), Louis XVIII (reign: 1814–1815; 1815–1824) and Charles X (reign: 1824–1830).Manheim Township, Lancaster County, Pennsylvania
Manheim Township is a township in Lancaster County, Pennsylvania established in 1729, which southernmost border meets the city limits of Lancaster. The population as of the 2010 census was 38,133.Parliament of the Bahamas
The Parliament of The Bahamas is the bicameral national parliament of Commonwealth of The Bahamas. The parliament is formally made up of the Queen (represented by the Governor-General), an appointed Senate, and an elected House of Assembly. It currently sits at Nassau, the national capital.
The structure, functions, and procedures of the parliament are based on the Westminster system.Philosophiæ Naturalis Principia Mathematica
Philosophiæ Naturalis Principia Mathematica (Latin for Mathematical Principles of Natural Philosophy), often referred to as simply the Principia , is a work in three books by Isaac Newton, in Latin, first published 5 July 1687. After annotating and correcting his personal copy of the first edition, Newton published two further editions, in 1713 and 1726. The Principia states Newton's laws of motion, forming the foundation of classical mechanics; Newton's law of universal gravitation; and a derivation of Kepler's laws of planetary motion (which Kepler first obtained empirically).
The Principia is considered one of the most important works in the history of science.The French mathematical physicist Alexis Clairaut assessed it in 1747: "The famous book of Mathematical Principles of Natural Philosophy marked the epoch of a great revolution in physics. The method followed by its illustrious author Sir Newton ... spread the light of mathematics on a science which up to then had remained in the darkness of conjectures and hypotheses."A more recent assessment has been that while acceptance of Newton's theories was not immediate, by the end of a century after publication in 1687, "no one could deny that" (out of the Principia) "a science had emerged that, at least in certain respects, so far exceeded anything that had ever gone before that it stood alone as the ultimate exemplar of science generally."In formulating his physical theories, Newton developed and used mathematical methods now included in the field of calculus. But the language of calculus as we know it was largely absent from the Principia; Newton gave many of his proofs in a geometric form of infinitesimal calculus, based on limits of ratios of vanishing small geometric quantities. In a revised conclusion to the Principia (see General Scholium), Newton used his expression that became famous, Hypotheses non fingo ("I formulate no hypotheses").Picander cycle of 1728–29
Picander's cycle of 1728–29 is a cycle of church cantata librettos covering the liturgical year. It was published for the first time in 1728 as Cantaten auf die Sonn- und Fest-Tage durch das gantze Jahr (Cantatas for the Sun- and feastdays throughout the year). Johann Sebastian Bach set several of these librettos to music, but it is unknown whether he covered a substantial part of the cycle. This elusive cycle of cantata settings is indicated as the composer's fourth Leipzig cycle, or the Picander cycle (German: Picander Jahrgang).Province of Carolina
The Province of Carolina was an English and later a British colony of North America. Carolina was founded in what is present-day North Carolina. Carolina expanded south and, at its greatest extent, nominally included the present-day states of North Carolina, South Carolina, Georgia, Alabama, Tennessee and Mississippi, and parts of modern Florida and Louisiana.Sir Robert Heath, attorney-general of King Charles I of England, was granted the Cape Fear region of America, incorporated as the Province of Carolana, in 1629. The charter was unrealized and ruled invalid, and a new charter was issued to a group of eight English noblemen, the Lords Proprietors, on March 24, 1663. It was not until 1663 that the province became officially known as "Carolina." Charles II granted the land to the eight Lords Proprietors in return for their financial and political assistance in restoring him to the throne in 1660. Charles II intended for the newly created province to serve as an English bulwark to contest lands claimed by Spanish Florida and prevent their northward expansion. Led informally by Anthony Ashley-Cooper, 1st Earl of Shaftesbury, the Province of Carolina was controlled from 1663 to 1729 by these lords and their heirs.
In 1669, the Fundamental Constitutions of Carolina divided the colony of Carolina into two provinces, Albemarle province in the north and Clarendon province in the south. Due to dissent over the governance of the colony, and the distance between settlements in the northern half and settlements in the southern half, in 1691 a deputy governor was appointed to administer the northern half of Carolina (Albemarle province). In 1712, the two provinces became separate colonies, the colony of North Carolina (formerly Albemarle province) and the colony of South Carolina (formerly Clarendon province).Although the division between the northern and southern governments became complete in 1712, both colonies remained in the hands of the same group of proprietors. A rebellion against the proprietors broke out in 1719 which led to the appointment of a royal governor for South Carolina in 1720. After nearly a decade in which the British government sought to locate and buy out the proprietors, both North and South Carolina became royal colonies in 1729.
