When you say scientist, what‘s the first thing that comes into your mind? They are the people who chose to allocate their time, expertise, knowledge and skills to companies and private entities in order to create state-of-the-art products that would make man’s existence and way of living easier. One of the main purposes of a scientist is to continuously acquire knowledge that describes and predicts the natural world. They use scientific methods to investigate a new phenomenon or correct previously established facts. They spend most of their time in researching and validating their theories. They always conduct thorough studies like what Stephen Hawking had done as a theoretical physicist and cosmologist. He discovered the theoretical prediction about the black hole emit radiation which is also called the Hawking radiation. Before publishing facts, scientists spend so much time validating, negating, and confirming their pre-established theories. There are two types of scientists – they are either categorized by field or by employer. Some of the examples of field scientists include astronomers, biologists, botanists, ecologists, chemists, meteorologist, paleontologist, epidemiologist, seismologist, archeologist, and earth scientists. When you say scientists by employer, they are working in academics, applied scientists, independent scientists, and government scientists. Some scientists managed to earn a fortune from their bestselling books. Some were invited for speaking engagements while others were recipients of special awards from prestigious organizations around the world for their scientific contributions and success. Aside from Hawking, some of the notable scientists are Stephen Hillenburg, Kathleen Taylor, and Mikhail Kalashnikov. Check out our compilation to get to know more about them.
