The two-period operator (..) specifies a numeric range in Google searches. 'olympics 1980..2000' finds pages with 'olympics' AND any number between 1980 and 2000 inclusive. This works for any numeric range, not just dates.

The link: operator finds all pages that link to a specific URL. 'link:www.whitehouse.gov' returns pages containing links to whitehouse.gov. This is useful for SEO research and finding backlinks.

The cache: operator shows Google's most recent cached version of a webpage. 'cache:www.plentysmart.com' displays when Google last crawled and indexed the site, indicating how fresh their information is. This helps diagnose SEO and indexing issues.

The 'related:' operator is a specific Google search operator that finds websites similar to the specified URL. When you search for 'related:www.yale.edu', Google returns a list of sites that it determines are related to Yale's homepage based on content and linking patterns. Other operators like 'link:' show sites that link TO the page, while 'like:' and 'showlike:' are not valid Google search operators.

Google can directly calculate mathematical expressions when you enter them in the search bar. The expression '((2*6)/3)^2' equals 16 (12/3=4, 4^2=16). You don't need special operators like 'calculate:', 'calc:', or 'show results:' - simply typing the mathematical expression works. Google's calculator recognizes standard mathematical notation and operators.

Google recognizes multiple natural language query formats for unit conversions. All of the listed queries - 'feet to meters', 'how many meters in a foot', 'one foot in meters', and '1 foot in meters' - are valid ways to ask Google to convert feet to meters. Google's natural language processing is flexible enough to understand different phrasing patterns for the same conversion request.

Google accepts multiple query formats for currency conversion. Whether you use natural language ('how many dollars in a pound', 'pounds to dollars') or specific currency codes ('1 gbp in usd', '1 pound in dollars'), Google can process all these formats correctly. The flexibility allows users to ask in whatever way feels most natural to them.

To get stock quotes in Google, you use the 'stocks:' operator followed by the stock symbol. Searching for 'stocks:goog' will return Google's current stock price along with relevant financial information. Other operators like 'ticker:', 'show:', 'price:' are not the correct syntax for stock quotes in Google Search.

The 'define:' operator is specifically designed to get definitions from Google. When you search 'define:quiz', Google returns a panel with multiple dictionary definitions, pronunciation, usage examples, and synonyms. Other formats like just the word 'quiz', 'definition:quiz', 'what is quiz', or '?quiz' may show some definition information but don't reliably provide a comprehensive list of definitions like the 'define:' operator does.

Guglielmo Marconi is credited as the inventor of radio for his pioneering work in wireless telegraphy. He shared the 1909 Nobel Prize in Physics for his contributions to wireless communication. While other scientists like Tesla, Popov, and Bose contributed to radio technology, Marconi made the first successful long-distance transmissions.
