Mechanisms for Conceptual Change in Physics. Student Perspectives, Computers and Motivation

Brin and Page, who met as Stanford University graduate students in computer science in 1995, developed a mathematical formula that ranked a Web page by how many other Web pages were linked to it, on the assumption that the more people linked to a certain page, the more important the page. The key breakthrough that enabled Google to become first among search engines was its ability to combine its PageRank technology with an analysis of page content, which determines which pages are most relevant to the specific search being conducted. Even though Google entered the market after other major search players, its answers were seen by people as more accurate and relevant to what they were looking for. The fact that one search engine was just a little better than the others led a tidal wave of people to switch to it. (Google now employs scores of mathematicians working on its search algorithms, in an effort to always keep them one step more relevant than the competition.) For some reason, said Brin, “people underestimated the importance of finding information, as opposed to other things you would do online ...»
