You can find a nice definition here: http://en.wikipedia.org/wiki/Biology

According to bing's dictionary:
1. science of life: the science that deals with all forms of life, including their classification, physiology, chemistry, and interactions 2. life in one place: the forms of life in a particular environment and their behavior, development, and history "the biology of desert regions" 3. particular organism's makeup: the structure and functioning of a particular organism "the biology of the fruit fly" [ Early 19th century.

The main three classifications of science( as per academic) are the following:
Physics
Chemistry
Biology( Botany and Zoology)
In common we have different classifications too..
computer science
social science.. etc..

Chemistry - is the science of matter and the changes it undergoes. The science of matter is also addressed by physics, but while physics takes a more general and fundamental approach, chemistry is more specialized, being concerned with the composition, behavior (or reaction), structure, and properties of matter, as well as the changes it undergoes during chemical reactions.

- It is a physical science which studies various substances, atoms, molecules, crystals and other aggregates of matter whether in isolation or combination, and which incorporates the concepts of energy and entropy in relation to the spontaneity of chemical processes.

get a uninstallation software like revo uninstaller and uninstall the previous installation.

the reason for the problem you are getting are the registry entries that are present for the previous installation.

use advance feature in uninstaller that will remove or display the entries ,remove them and you are good to go

I understand the pain and how difficult it is to work on a science document!!!!!!!!!!!!
By the way if you are using the office suite applications such as Word 2007 or word 2010, you can insert the symbols easily.
To insert a symbol or special character into your document, follow these steps in Word 2007:
1. Position the cursor where you would like to insert the symbol or character
2. Open the Insert ribbon
3. Click Symbol in the Symbol section
4. A menu will appear with a small selection of symbols
5. If you don't see the symbol or character you'd like to insert, click More Symbols
6. Use the controls to select between symbols and special characters. Additional tools on the symbols tab will help you expand or narrow your selection
7. When you find your symbol or special character, click it and then click Insert
8. When you're done, click Close
The symbol or special character will appear at the appropriate place in your document.
Hope this helps!!!

Well, I am helpless regarding developing a keyboard with all those scientific symbols,.LOL
