Google Searches Info

  1. Either/or. Google normally searches for pages that contain all the words you type in the search box, but if you want pages that have one term or another (or both), use the OR operator -- or use the "|" symbol (pipe symbol) to save you a keystroke. [dumb | little | man]
  2. Quotes. If you want to search for an exact phrase, use quotes. ["dumb little man"] will only find that exact phrase. [dumb "little man"] will find pages that contain the word dumb and the exact phrase "little man".
  3. Not. If you don't want a term or phrase, use the "-" symbol. [-dumb little man] will return pages that contain "little" and "man" but that don't contain "dumb".
  4. Similar terms. Use the "~" symbol to return similar terms. [~dumb little man -dumb] will get you pages that contain "funny little man" and "stupid little man" but not "dumb little man".
  5. Wildcard. The "*" symbol is a wildcard. This is useful if you're trying to find the lyrics to a song, but can't remember the exact lyrics. [can't * me love lyrics] will return the Beatles song you're looking for. It's also useful for finding stuff only in certain domains, such as
    educational information: ["dumb little man" research *.edu].
  6. Advanced search. If you can't remember any of these operators, you can always use Google's advanced search.
  7. Definitions. Use the "define:" operator to get a quick definition. [define:dumb] will give you a whole host of definitions from different sources, with links.
  8. Calculator. One of the handiest uses of Google, type in a quick calculation in the search box and get an answer. It's faster than calling up your computer's calculator in most cases. Use the +, -, *, / symbols and parentheses to do a simple equation.
  9. Numrange. This little-known feature searches for a range of numbers. For example, ["best books 2002..2007] will return lists of best books for each of the years from 2002 to 2007 (note the two periods between the two numbers).
  10. Site-specific. Use the "site:" operator to search only within a certain website. [site:dumblittleman.com leo] will search for the term "leo" only within this blog.

 Nanotechnology, in one sense, is the natural continuation of the miniaturization revolution that we have witnessed over the last decade, where millionth of a metre (10 -6m) tolerances (microengineering) became commonplace, for example, in the automotive and aerospace industries enabling the construction of higher quality and safer vehicles and planes. It was the computer industry that kept on pushing the limits of miniaturization, and many electronic devices we see today have nano features that owe their origins to the computer industry – such as cameras, CD and DVD players, car airbag pressure sensors and inkjet printers.
