Having a scientific temperament is quite good. You can observe various things happening around you in a scientific manner which others won’t even notice. You are a scientist in yourself if you observe things with keenness. Anything which is happening around you is science. Science has three main branches of physical science, abstract science, and life science. These three contribute each other in various phenomena miraculously, without even your knowledge. One who discovers these phenomena is called a scientist. Every scientist has to toil a lot to discover a theory or invent a thing. Not every theory is right in the first instance. It has to go through various trial and error experimentation and calculations to reach a final conclusion. Sometimes the scientists have to wait for years to come to a final answer. Some theories go wrong even after putting in so many efforts.
