83. Triangle To Square: A Hinged Dissection We thank him for this dissection, originally credited to dudeney in 1907. written by the American Sam Loyd and the Englishman henry Ernest dudeney. http://math.nmsu.edu/breakingaway/Lessons/T2S/Triangle2Square.htm

Triangle to square: A hinged dissection Background: Greg Frederickson's book , was published in 2002 by Cambridge University Press. We thank him for this dissection, originally credited to Dudeney in 1907. We have adapted it for use with children. From his website, http://www.cs.purdue.edu/homes/gnf/book2.html "A geometric dissection is a cutting of a geometric figure into pieces that we can rearrange to form another figure. As visual demonstrations of relationships such as the Pythagorean theorem, dissections have had a surprisingly rich history, reaching back to Arabian mathematicians a millennium ago and Greek mathematicians more than two millennia ago. As mathematical puzzles they enjoyed great popularity a century ago, in newspaper and magazine columns written by the American Sam Loyd and the Englishman Henry Ernest Dudeney. Loyd and Dudeney set as a goal the minimization of the number of pieces. Their puzzles charmed and challenged readers, especially when Dudeney introduced an intriguing variation in his 1907 book The Canterbury Puzzles . After presenting the remarkable 4-piece solution for the dissection of an equilateral triangle to a square, Dudeney wrote: 'I add an illustration showing the puzzle in a rather curious practical form, as it was made in polished mahogany with brass hinges for use by certain audiences. It will be seen that the four pieces form a sort of chain, and that when they are closed up in one direction they form a triangle, and when closed in the other direction they form a square.”

87. The Fibonacci Numbers And Golden Section In Nature - 1 The English puzzlist, henry E dudeney (1857 1930, Puzzle books by henry Edudeney. Book Amusements in Mathematics, Dover Press, 1958, 250 pages. http://www.mcs.surrey.ac.uk/Personal/R.Knott/Fibonacci/fibnat.html

Fibonacci Numbers and Nature This page has been split into TWO PARTS. This, the first , looks at the Fibonacci numbers and why they appear in various "family trees" and patterns of spirals of leaves and seeds. The second page then examines why the golden section is used by nature in some detail, including animations of growing plants. Contents of this Page The icon means there is a Things to do investigation at the end of the section. Rabbits, Cows and Bees Family Trees Fibonacci's Rabbits.. Dudeney's Cows Honeybees and Family Trees ... More Rabbits, Cows and Bees Family Trees Let's look first at the Rabbit Puzzle that Fibonacci wrote about and then at two adaptations of it to make it more realistic. This introduces you to the Fibonacci Number series and the simple definition of the whole never-ending series. Fibonacci's Rabbits The original problem that Fibonacci investigated (in the year 1202) was about how fast rabbits could breed in ideal circumstances. Suppose a newly-born pair of rabbits, one male, one female, are put in a field. Rabbits are able to mate at the age of one month so that at the end of its second month a female can produce another pair of rabbits. Suppose that our rabbits

88. Perl Programming Problems Here s another puzzle from the pen of mathematician henry dudeney. The followingis a rather curious puzzle. Find the smallest number that, when divided http://www.ualberta.ca/~hquamen/303/problems.html

Listed below are some sample programming problems that you might like to work on for your Perl project. If you'd rather tackle a different problem, please check with me to insure that your idea is workable within the scope of the assignment. Rot 13 n! Mathematicians define n! (pronounced “n factorial”) as the product of all the numbers from 1 to n. (that is, you multiply all the numbers, so 5! = 1 * 2 * 3 * 4 * 5). Write a program that will calculate n! for a value of n that the user inputs. (Don’t let the user input negative numbers.) Can your program calculate correctly that 0! = 1 ? (If you’re looking for a more challenging algorithm, try a recursive subroutine.) Fibonacci Sequence Leonardo Pisano, better known by his nickname Fibonacci, was an Italian mathematician who lived from 1170-1250. He is famous for investigating a sequence of numbers that begins as follows: Each number in the sequence is the sum of the previous two numbers. Write a program that accepts a number, n, from the user and finds the nth Fibonacci number. Entering “4” for example, should return the output “2”; entering “8” should return “13”. Be sure to check the user’s input for validity. (Again, for a more challenging solution, try a recursive subroutine.) Charting Random Numbers Write a program to select 100 random numbers between 1 and 10. Count how many occurrences of each number there are, and print out a distribution chart similar to the following:

It's free! Save it. A problem that has become a staple in calculus textbooks is the box problem: Determine an open box of largest volume that we can form from a rectangular sheet by cutting squares out of the corners, folding up the sides, and then gluing or soldering the joints. Isaac Todhunter [19] included it as an exercise in his calculus textbook a century and a half ago. The problem is a variation of a considerably older problem, which corresponds to the task of forming one quarter of an open box. That older problem was posed by the seventeenth century French mathematician Pierre de Fermat [3] and solved by the Dutch mathematician Frans van Schooten [20]. The box problem entered the mathematical puzzle literature when it appeared in 1903 in Henry Dudeney's puzzle column in The Weekly Dispatch [5]. In 1908 he rephrased it for his puzzle column in Cassell's Magazine [6], adding a picturesque illustration by Paul Hardy, before he included the revised puzzle in his book Amusements in Mathematics [7]. The original version is delightfully quaint:

Skip to comments Carrera's Chess John Gollon, well known by chess variant enthousiasts for his book on chess variants , now unfortunately out of print, was working on a second book on chess variants. Also unfortunately, this second book was never published. Gollon has sent some materials from a draft of the book to Eric Greenwood (in 1976): the description given here is based on part of these writings by Gollon. D. Pietro Carrera invented this chess variant in the 17th century. He wrote a long book on chess, called Il Gioco delgi Scacchi , and published it in 1617 in Miltello in Sicily. The variant was probably little played. The game was again mentioned by Ben Foster in his booklet on Chancellor Chess , and in a book from 1804 called An Introduction to the History and Study of Chess . Also

Wednesday December 11, 2002 Delphi For Fun Newsletter #30 Wow! Has it really been 2 months since the last newsletter? I guess time really does fly when you're having fun. Halloween, Thanksgiving and a successful deer season have all come and gone. We're iced in today, so it's a good time to get caught up and let you occasional visitors see what has been going on. I have my new 2.4 ghz P4 up and running - homebuilt of course. The Gigabyte GA-8IEXP motherboard has integrated USB 2.0, and Firewire ports as well as sound and networking and onboard RAID so my hard drive is now mirrored for reliability. Add an ATI Radeon 7500 video card, 512mb of DDR memory, and an extra 40gb drive to go with one I had and it makes a decent system for $600. To be honest, the old Celeron 800 was perfectly adequate - but once in while action is required just so you can start spending your spare time thinking about something else. We passed 30,000 home page visitors this week and are averaging about 1000 total website hits per day, mostly search engine referrals to specific topic pages. I added a "Top Downloads" link from the home page a few weeks ago - it's updated weekly and shows a total of about 90,000 downloads in the past 12 months! Thanks for all of your feedback this past year - it has encouraged me to continue the site for another year. Here's wishing all a Happy Holiday Season!

Saturday, November 10, 2001 M I N D G A M E S Henry's Nobel Aditya Rishi K NOWING that Titanic sank on its maiden voyage; mathematician Henry Ernest Dudeney boards the train named Titanic with a sinking heart. His heart will go on, but the train's heart, its engine, slows down, an hour after starting from Anglechester and going towards Clinkerton. Henry finds that he is travelling with an engineer and an astronomer, besides Nobel laureates - physicist Einstein and chemist Fritz Haber. The speed of the train induces sleep and they retire to their adjoining cabins. First the engineer's coffee maker catches fire. He smells the smoke, wakes up, unplugs the coffee maker, throws it out of the window, and goes back to sleep. Later, Haber the chemist smells smoke too. He wakes up and sees that a cigarette butt has set the trashcan on fire. He says to himself, "Hmm how does one put out a fire? One can reduce the temperature of the fuel below the flash point and isolate the burning material from oxygen, or both. This could be accomplished by applying water." He picks up the trashcan, puts it in the shower stall, turns on the water, and, when the fire is out, goes back to sleep. Nobel pastime When Nobel laureates have to pass time, they try to find out where in pi their birthdays first occur. If anyone of them was born February 11, 1949, he or she would search for the string '21149' in the digits of pi. Everyone's birthday is hidden in the digits of pi. Is your birthday there?

The Zen of Magic Squares, Circles, and Stars: An Exhibition of Surprising Structures Across Dimensions Clifford A. Pickover Princeton University Press, 2002 "A refreshing new look at a timeless topic, brimming over with ideas, littered with surprising twists. Anyone who loves numbers, anyone who enjoys puzzles, will find The Zen of Magic Squares, Circles, and Stars compulsive (and compulsory!) reading." Ian Stewart, University of Warwick Order from Amazon.com. "At first glance magic squares may seem frivolous (Ben Franklin's opinion, even as he spent countless hours studying them!), but I think that is wrong. The great nineteenth-century German mathematician Leopold Kronecker said 'God Himself made the whole numberseverything else is the work of men,' and Cliff Pickover's stimulating book hints strongly at the possibility that God may have done more with the integers than just create them. I don't believe in magic in the physical world, but magic squares come as close as we will probably ever see to being mathematical magic." - Paul J. Nahin, University of New Hampshire, author of Duelling Idiots and Other Probability Puzzlers
