Scientists conduct experiments with an attempt to prove genuine hypotheses; scientists by accident discover new things. However, scientists must be keen to observe and interpret observations of their experiments (Chris, 2009).
A prepared mind means that a scientist should have a deep understanding of their field of specialization. This will enable the scientist to interpret the accidental observations and relate the new phenomena with his or her existing work. When there is a chance of discovering new things only those who have prepared minds discover and learn these new things. Scientists, who have a positive attitude and are dedicated to their work, are the ones who have the capability to identify chances of learning and make discoveries out of the chances. Scientific knowledge enables people to interpret accidental observations based on the on the knowledge. Scientific experiments involve risks especially when the scientists are using chemical elements. Marie Curie used radioactive elements, which releases enormous energy through radiation. Unknowingly, these radiations could have led to serious damage if they were not handled carefully (Chris,
