The Science Dictionary is a specialized science search engine that queries billions of the web's top science pages for scientific information. The Science Dictionary was founded in 2006 and has since processed over three million (3,000,000+) queries. Every month, we receive over 250,000 page views from over 40,000 people worldwide who visit our site to learn more about a particular science topic. The Science Dictionary has been featured as a trusted resource by numerous educational institutes (K-12 and higher education) in the United States, the United Kingdom, and Canada. Researchers, students, and professionals around the world use The Science Dictionary as their goto website for finding relevant scientific information.

TDS vs Google

The Science Dictionary leverages Google's over one million servers and enormous web index of over 13 trillion web pages to perform its search queries. On top of Google's search index, The Science Dictionary has implemented a filtering system that determines which websites are trusted, science websites and which websites aren't.

In layman terms, every time you perform a search on The Science Dictionary, The Science Dictionary first accesses Google's 13 trillion page index to find matching pages. Then, The Science Dictionary takes the returned results and filters them so that only pages that are thematically matched with your search term are returned.

For example, if you search for the term "wave" on Google, you'll get a search result containing information about Google Wave, WAVE the company, a governent organization named Wave, and a news station named WAVE. As you can see, most of the information that Google returns isn't relevant to science since Google doesn't know whether you're searching for wave in a scientific context or in a business context.

On the other hand, if you search for the same term "wave" on The Science Dictionary, you'll get a search page with relevant scientific information about waves in physics, neuroscience, geosystems...etc.

Product Reviews

Recently, the TSD team has started writing product reviews for select science and tech products. Because we know that there are a lot of websites out there that already do tech product reviews, instead of focusing on the quantity of reviews, we're focusing on quality. For many of our reviews, we place about half a dozen orders for the product we're testing (using our own money, we never accept donations from the product vendors), then we distribute the products to multiple TSD team members who each test the product for at least three months.

At the end of the few months, one team member collects detailed feedback from all of the other team members and writes a comprehensive review, covering the product. Compared to other tech product review sites (which often just spend a day or a week with the product they're testing), this method results in a much more complete review. For example if you read our Ting review, you'll see that we try to go above and beyond the boundaries of a normal product review. Not only do we review the coverage of Ting (a cell phone service provider), we also discuss its business model, its technology, and its customer support.
