[Misc] Scratch

(Jul 15, 2008)


Scratch is a new programming language that makes it easy to create your own interactive stories, animations, games, music, and art -- and share your creations on the web.

Scratch is designed to help young people (ages 8 and up) develop 21st century learning skills. As they create Scratch projects, young people learn important mathematical and computational ideas, while also gaining a deeper understanding of the process of design.

Scratch is developed by the Lifelong Kindergarten group at the MIT Media Lab, in collaboration with the UCLA Graduate School of Education and Information Studies, with financial support from the National Science Foundation, Intel Foundation, and MIT Media Lab research consortia.

Scratch is available free of charge, go to Download.
Currently available for Mac OSX and Windows ( system requirements)

To find more about the ideas underlying Scratch, visit our page for Educators.

To learn how to use Scratch, go to Support.

To read research papers on Scratch, see Research .

To find out who is working on Scratch, see the Credits.

To read what people are saying about Scratch, see Quotes.

In mathematics, the Fibonacci numbers are a sequence of numbers named after Leonardo of Pisa, known as Fibonacci. Fibonacci's 1202 book Liber Abaci introduced the sequence to Western European mathematics, although the sequence had been previously described in Indian mathematics.[2][3]

The first number of the sequence is 0, the second number is 1, and each subsequent number is equal to the sum of the previous two numbers of the sequence itself. In mathematical terms, it is defined by the following recurrence relation:

1. \\ \end{cases} " src="http://upload.wikimedia.org/math/7/6/f/76f99713cf111eb035d908228c351710.png">

That is, after two starting values, each number is the sum of the two preceding numbers. The first Fibonacci numbers (sequence A000045 in OEIS), also denoted as Fn, for n = 0, 1, 2, … ,20 are:[4][5]

F0 F1 F2 F3 F4 F5 F6 F7 F8 F9 F10 F11 F12 F13 F14 F15 F16 F17 F18 F19 F20
0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181 6765





Every 3rd number of the sequence is even and more generally, every kth number of the sequence is a multiple of Fk.

The sequence extended to negative index n satisfies Fn = Fn−1 + Fn−2 for all integers n, and F−n = (−1)n+1Fn:

.., −8, 5, −3, 2, −1, 1, followed by the sequence above.
