Encyclopedia of Integer Sequences

[Rohit Khare]

This risks being old bits, but was just too funny for words... 65K+ 
integer sequences!

Even more amusing: The Dictionary of Real Numbers. Not online, but 
used on Amazon for $125:

So, even older bits that put it in context:

>In my daydream, Neil Sloane and Simon Plouffe are contestants on 
>"Jeopardy," the TV game show. Sloane picks the category "Integer 
>Sequences" for $400, and Alex Trebek reads the answer: "1, 1, 2, 3, 
>5, 8, 13, 21...." Sloane instantly supplies the question: "What are 
>the Fibonacci numbers?" Later it is Plouffe's turn, and he selects 
>"Real Numbers" for $1,000. Trebek reads out an answer: 
>"1.618033989," and Plouffe responds with the question: "What is phi, 
>or the golden mean--the limiting value of the ratio of successive 
>Fibonacci numbers?"
>
>In real life Sloane and Plouffe are not competitors but 
>collaborators. Sloane is a mathematician at AT&T Bell Laboratories, 
>well known for his work in graph theory, combinatorics and geometry. 
>He is also the author of the Handbook of Integer Sequences, a 
>compendium of some 2,300 sequences, published in 1973. Plouffe, a 
>mathematician now at Simon Fraser University in British Columbia, is 
>another collector of numbers and sequences, who volunteered a few 
>years ago to help revise and expand the Handbook. Sloane and Plouffe 
>are coauthors of the new edition, published last year as the 
>Encyclopedia of Integer Sequences. It is a much-enlarged and 
>enriched work, with more than 5,400 entries.
...
>Following his work on the Encyclopedia of Integer Sequences, Plouffe 
>has gone on to develop an analogous Internet server for real 
>numbers, called the Inverse Symbolic Calculator, or ISC. The 
>calculator is "inverse" in the sense that you give it a number and 
>ask where the number might have come from, rather than giving it a 
>formula and requesting a solution. You do not ask the calculator for 
>the value of e/pi + 1; you supply the numerical result 
>1.8652559794322, and the program suggests this expression as one 
>possible source.

>There are some outright jokes, such as M4961: 1, 15, 29, 12, 26, 12, 
>26, 9, 23, 7, 21.... The description given is "Dates at fortnightly 
>intervals from Jan. 1."
...
>  In 1990 Jonathan Borwein and Peter Borwein, who were then at 
>Dalhousie University in Nova Scotia, published A Dictionary of Real 
>Numbers. This is not a book to keep by your bedside, although its 
>columns and columns of eight-digit numbers can make it a valuable 
>reference. ("Wait for the movie," is the usual advice, but in this 
>case it's "Wait for the Web site.") Plouffe's compilation of real 
>numbers began independently of the Dictionary, but Plouffe and the 
>Borweins have since made common cause. Jonathan and Peter Borwein 
>now direct the Center for Experimental and Constructive Mathematics 
>at Simon Fraser University, where Plouffe has become a research 
>associate.
