a page ranking system based on the rules of academic citation. In academia, citations are like currency. Your publication will stand in higher esteem the more other publications cite it. As graduate students at Stanford University, Larry Page and Sergey Brin created their search algorithm with the idea of ranking pages based on how often other pages "cite" them -- or, in this case, link back to them. And that's the very, very basic premise of the site that few of us could do without. But are you really getting the most out of it? Take a look below to find out!

Computational thinking (CT) involves a set of problem-solving skills and techniques that software engineers use to write programs that underlie the computer applications you use such as search, email, and maps. However, computational thinking is applicable to nearly any subject. Students who learn computational thinking across the curriculum begin to see a relationship between different subjects as well as between school and life outside of the classroom. Specific computational thinking techniques include: problem decomposition, pattern recognition, pattern generalization to define abstractions or models, algorithm design, and data analysis and visualization.
