During their first encounter, both Sergey Brin and Larry Page found each other obnoxious due to differences in personalities. However this didn’t keep them from creating what is today’s most popular engine. A few months after they had first met, Page found himself attracted to the very complex idea of the World Wide Web. The mathematical characteristics of the Web was what interested him. His main focus was to organize the Web in a form in which you could easily backtrack how you got the the result you wanted. He began by creating a crawler, what he called BackRub, to calculate the sum of links in the Web. Soon after, he was able to categorize these links by ranking, importance, and relativity. By this point, Sergey Brin was truly interested in helping out with Page’s Project and finally teamed up. Together they created a ranking system that rewarded links that came from sources that were important and penalized those that did not.
