###### In the News (Fri 24 May 19)

 The Dullness of 1729 The famous anecdote is that during one visit to Ramanujan in the hospital at Putney, Hardy mentioned that the number of the taxi cab that had brought him was 1729, which, as numbers go, Hardy thought was "rather a dull one". At this, Ramanujan perked up, and said "No, it is a very interesting number; it is the smallest number expressible as a sum of two cubes in two different ways." This was the sort of thing that prompted Littlewood to say "every positive integer was one of [Ramanujans'] personal friends". So if anyone ever tells me that 1729 is a dull number, I intend to affect a moment of contemplation and then say "Not at all, it is the first occurrance of all ten digits consecutively in the decimal representation of e". www.mathpages.com /home/kmath028.htm   (848 words)

 1729 - The Infosphere 1729 is known as the Hardy-Ramanujan number, after a famous anecdote of the British mathematician G. Hardy regarding a hospital visit to the Indian mathematician Srinivasa Ramanujan. 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 unfavorable omen. Because in base 10 the number 1729 is divisible by the sum of its digits, it is a Harshad number. futurama.overt-ops.com /index.php?title=1729   (433 words)

 [No title] Lynch [Page 4] RFC 1729 Using the Z39.50 in the Internet Environment December 1994 Real-world implementations need to be prepared to deal with both TCP ABORT and CLOSE anyway, so this approach presents no additional problems, other than the somewhat ambiguous nature of the type of association termination. In the OSI environment, the partners in a Z39.50 association are assumed to agree, either through presentation negotiation as part of association establishment, or later, dynamically, as part of the PRESENT process (through the use of the alter presentation context function at the presentation layer), on which record syntaxes the two entities commonly know. A number of implementations are already employing this field, and interoperable implementations might be wise to include code which at least ignores the presence of such fields rather than considering their presence an error (in contravention of the standard). www.ietf.org /rfc/rfc1729.txt   (2476 words)

 1729 (number) - Wikipedia, the free encyclopedia 1729 is known as the Hardy-Ramanujan number, after a famous anecdote of the British mathematician G. The quotation is sometimes expressed using the term "positive cubes", as the admission of negative perfect cubes (the cube of a negative integer) gives the smallest solution as 91 (which is a factor of 1729): The physicist Richard Feynman demonstrated his abilities at mental calculation when, during a trip to Brazil, he was challenged to a calculating contest against an experienced abacist. en.wikipedia.org /wiki/1729_(number)   (776 words)

 A Simple Refutation of Gödel's Theorem To write down the number 1729, therefore, formal logic uses 1730 symbols -- and, by Gödel's numbering system, each of these symbols must be assigned a numerical value of either 1 or an integer greater than 1. And then, generalising, he could have a general provability predicate which used the existential quantifier, and said just that there was a number which was the Gödel number of a sequence that was a proof of the well-formed formula whose Gödel number was the second number. These two manoeuvres enable Gödel to refer to well-formed formulae by numbers, and to represent provability as a property of numbers definable in terms of the simple arithmetical operations of addition and multiplication, though the definitions are themselves very complicated. homepage.mac.com /ardeshir/Godel-SimpleRefutation.html   (2104 words)

 UDP 1729 - Port Protocol Information and Warning! UDP Port 1729 may use a defined protocol to communicate depending on the application. If you have information on UDP port 1729 that is not reflected in our database, please leave a comment with the help desk. Like TCP (Transmission Control Protocol), UDP is used with IP (the Internet Protocol) but unlike TCP on Port 1729, UDP Port 1729 is connectionless and does not guarantee reliable communication; it's up to the application that received the message on Port 1729 to process any errors and verify correct delivery. www.auditmypc.com /port/udp-port-1729.asp   (358 words)

 AS-1729 Antenna The MX-6707 base tuning unit uses capactance and inductance to match the antenna, not lossy resistance as is used on the newer matching bases that are now needed for frequency hopping radios like the SINCGARS. There is also a mast adapter that allows the AS-1729 to be mounted on a GRA-4 or RC-292 mast. The AS-2731/GRC, NSN 5985-01-017-0785, as described in TM 11-5985-355-13 is very similar in appearance to the AS-1729, but has an operating frequency range of 30 to 80 MHz. www.pacificsites.com /~brooke/AS1729.shtml   (1395 words)

 Anglo-Spanish War, 1727-1729 The British maintained their hold on Gibraltar with little difficulty, and the conflict degenerated into a war of words until both sides eventually lost interest. The end of conflict was sealed by the Treaty of Sevilla (1729) leaving Britain in possession of Gibraltar. A year later the last of the Farnese dukes of Parma died, leaving that succession problem still unresolved. www.regiments.org /wars/18thcent/27spain.htm   (614 words)
