My intention, in short, is to give you some pointers on successful science writing. By taking to heart the ideas outlined below you should be able to avoid some of the most common pitfalls encountered by students writing about science. I can't help you understand the material, that's up to you, but when it comes to presenting your ideas, these notes may be of help. Below is a list of tips that you may find useful to keep in mind as you write your papers. Some are more inspirational, some more practical, some are underscored by a quotation that emphasizes the tip.
Writing is an act of communication from writer to reader.
What you write may make sense to you, but if it comes across as confused, disorganized or overly complex to the reader you have not succeeded. Put yourself in the place of the reader and review the work from that point of view. The need for organization is illustrated nicely by the following exchange between two of Lewis Carroll's most famous characters. You need to know where you are going in your paper so that you'll have a map to guide you as you make decisions about the best way to get there. In presenting the material you have carefully organized, remember that the reader only knows what you make explicit.
