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)

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 F_n, 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 F_k.

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

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

A compiler is a computer program that transforms human readable source code of another computer program into the machine readable code that a CPU can execute.

The act of transforming source code into machine code is called "compilation". This is the opposite to the process of interpretation.

Example of the compiler is Java, C and soon

What is Source Code? Before we learn it, we should know well about it, here is the definiton of source code



DEFINITION - Source code and object code refer to the "before" and "after" versions of a computer program that is compiled (see compiler) before it is ready to run in a computer. The source code consists of the programming statements that are created by a programmer with a text editor or a visual programming tool and then saved in a file. For example, a programmer using the C language types in a desired sequence of C language statements using a text editor and then saves them as a named file. This file is said to contain the source code. It is now ready to be compiled with a C compiler and the resulting output, the compiled file, is often referred to as object code. The object code file contains a sequence of instructions that the processor can understand but that is difficult for a human to read or modify. For this reason and because even debugged programs often need some later enhancement, the source code is the most permanent form of the program.

When you purchase or receive operating system or application software, it is usually in the form of compiled object code and the source code is not included. Proprietary software vendors usually don't want you to try to improve their code since this may created additional service costs for them. Lately, there is a movement to develop software (Linux is an example) that is open to further improvement and here the source code is provided.

In large program development environments, there are often management systems that help programmers separate and keep track of different states and levels of code files. For script (noncompiled or interpreted) program languages, such as JavaScript, the terms source code and object code do not apply since there is only one form of the code.
