The technology behind Google's great results As a Google user, you're familiar with the speed and accuracy of a Google search. How exactly does Google manage to find the right results for every query as quickly as it does? The heart of Google's search technology is PigeonRank™, a system for ranking web pages developed by Google founders Larry Page and Sergey Brin at Stanford University. Building upon the breakthrough work of B. F. Why Google's patented PigeonRank™ works so well PigeonRank's success relies primarily on the superior trainability of the domestic pigeon (Columba livia) and its unique capacity to recognize objects regardless of spatial orientation. By collecting flocks of pigeons in dense clusters, Google is able to process search queries at speeds superior to traditional search engines, which typically rely on birds of prey, brooding hens or slow-moving waterfowl to do their relevance rankings.

PowerMeter We launched Google PowerMeter as a free energy monitoring tool to raise awareness about the importance of giving people access to their energy information. PowerMeter included key features like visualizations of your energy usage, the ability share information with others, and personalized recommendations to save energy. We partnered with device manufacturers and utilities around the world. Many of our partners now have new options available for accessing energy information. We are pleased that PowerMeter helped demonstrate the importance of access to energy information, and created a model for others. We continue to see encouraging results about the importance of access to energy data. Momentum is building toward making energy information more readily accessible, and it’s exciting to see others drive innovation and pursue opportunities in this important new market. We’re proud of what we’ve accomplished with PowerMeter and look forward to what will develop next in this space.

Satire for Smart People; The Truth for You The Anatomy of a Search Engine Sergey Brin and Lawrence Page {sergey, page}@cs.stanford.edu Computer Science Department, Stanford University, Stanford, CA 94305 Abstract In this paper, we present Google, a prototype of a large-scale search engine which makes heavy use of the structure present in hypertext. 1. (Note: There are two versions of this paper -- a longer full version and a shorter printed version. 1.1 Web Search Engines -- Scaling Up: 1994 - 2000 Search engine technology has had to scale dramatically to keep up with the growth of the web. 1.2.

PROJECT GUTENBERG Publications by Googlers Google publishes hundreds of research papers each year. Publishing is important to us; it enables us to collaborate and share ideas with, as well as learn from, the broader scientific community. Submissions are often made stronger by the fact that ideas have been tested through real product implementation by the time of publication. We believe the formal structures of publishing today are changing - in computer science especially, there are multiple ways of disseminating information. Open Source We understand the value of a collaborative ecosystem and love open-source software. Product and Feature Launches With every launch, we're publishing progress and pushing functionality. Industry Standards Our researchers are often helping to define not just today's products but also tomorrow's. Resources "Resources" doesn't just mean tangible assets but also intellectual. Impact Couple big challenges with big resources and Google offers unprecedented research opportunities.

... having a bad day? Anger management (the wrong number story) Here are 5 ways to improve your site's rank in Google In April, Americans conducted a staggering 15.5 billion Web searches. Studies show that the first result receives about 40% of clicks. These days, simply creating a great website won't attract more customers to your business. To rank well on Google and other search sites, you have to optimize your site. There's a lot to SEO, and it requires patience; it can take months to see results. Choose keywords carefully Your keyword phrase is the search term that leads visitors to your site. Check the popularity of keywords with a tool like Google Adwords' Keyword Estimator.

Of course, you also need to use your keyword phrase within your content. Pay attention to links Search engines see incoming links as votes for your site. With links, reputation is important. Hire an expert carefully

Science/Nature | Virgin Galactic: The logical next step The news that Sir Richard Branson has signed a deal to take paying passengers into space suggests the Ansari X-Prize has achieved its goal of bringing space tourism closer to the masses. One of the aims behind the $10m (£5.7m) challenge was to galvanise enthusiasm for private manned spaceflight, thereby bringing "out of this world" tourism within reach of ordinary people. In the past, space travel has been open only to the privileged few; either government-back astronauts or millionaires with enough spare cash to book a flight on a Russian Soyuz rocket to the International Space Station. If and when the Virgin venture - dubbed Virgin Galactic - begins offering its first spaceflights, the tickets will still be expensive. But Sir Richard says prices will eventually come down to a level where "masses of people" will get to enjoy the space experience. Five Virgin Galactic SpaceShips are to be built. "[The Ansari X-Prize] has succeeded in doing what it set out to do. Short but sweet Major step
