A selection of the best google tools and services

Google used to only answer simple questions like "who's the prime minister of Canada?" or "what's the population of China?". Thanks to the Knowledge Graph project, a RDF schema algorithm, Google can answer even more complicated questions like "who played Batman?", "what's the latest album of Celine Dion?", "what are the main attractions in Spain?". The "Hummingbird" update to the Google search engine was announced in September 2013. The update was introduced over the month prior to the announcement and allows users ask the search engine a question in natural language rather than entering keywords into the search box

Google's corporate philosophy includes principles such as "you can make money without doing evil," "you can be serious without a suit," and "work should be challenging and the challenge should be fun." New employees are called "Nooglers," and are given a propeller beanie cap to wear on their first Friday.
