-3 line rule of thumb: Avoid at all cost sentences that run for more than 3 lines (in a normal 12pt font document). This will avoid run-on and complicated sentences and there is nearly never the need to have a single sentence be longer.
-Yoda-ism: "A curious padawan are you?"...ya you get it even you and I can sometime write thing in a "reverse order", look out for those.
-Affect vs effect: As a verb -in scientific writting- you should use "affect" 99% of the time. It means to have an impact. "To effect" means "to put into effect" and is usually reserved for technical or legal jargon. As a noun, you will use "effect" 95% of the time since "affect" describes the emotional phenomenon.
