I'll start with the most important. My wish experimenters. In his statement in detail describe the conditions of the experiment. When negligent description of the experiment created by theory is often incorrect. If, in the course of the experiment, something went wrong, please note, can you stand at the threshold of the opening! History knows many such cases. For example, the opening of the induction of electric currents, or the discovery of X-rays by Röntgen. There are a great many such stories.
