The Scientific Enterprise A scientific meeting, communication, and debate are important to the development of scientific explanations.
Steps in the Scientific Method • 1. Observation • 2. Formulation of Rules • 3. Development of Hypothesis, Theory • 4. Testing of the hypothesis or theories by further observation
Physics Physics is the study of the basic characteristics of matter and its interactions. Physics can be divided into classical physics and modern physics. Classical Physics: Mechanics, Thermodynamics, Electricity and Magnetism, and Optics. Modern Physics: Atomic physics, Nuclear Physics, Particle physics, and Condensed-Matter physics.
