When editing maths textbooks, you might want to check the maths. This is no longer tedious and time-consuming, because there are websites that will do the maths for you. I have found a very good calculator that can do differentiation; it can even take you through all the steps. You know that feeling when you're working through some physics, and you need to plug in the value of Planck's constant? Or the mass of an electron? Well, I have 40 of these constants right on my calculator. Moreover, for switching between metric and imperial, the calculator also has 40 conversion factors built in; I just type in the numbers, and it does all the maths.

This is a database of journal articles, mainly in the physical sciences. I find it useful to check reference details: to find a particular reference, choose 'Browse' and follow the links to find the correct journal code. http://www.picturedots.com/

There is, of course, a website for Webster's dictionary and this is it. Actually, the website is more than a dictionary; it also includes a thesaurus and an encylopaedia, and it has lots of fun extras, words of the day, lists, quizzes, and so on. http://ieeexplore.ieee.org/Xplore/home.jsp
This IEEE website is useful when checking references, because it has details for IEEE conference proceedings as well as IEEE journals. http://www.bacterio.net/ This is another website for checking bacteria, with names, strains and accession numbers |
