Study Notes
Science
Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about phenomena, based on empirical evidence. It encompasses many disciplines, two of which are Chemistry and Physics. These fields have been instrumental in shaping our understanding of the world around us.
Chemistry
Chemistry is the study of matter, its properties, how different types interact, reactions that change one type into another, and the general principles observed when these reactions occur. Chemists seek to describe and explain the molecular basis of macroscopic chemical compound properties through the investigation of atomic scale structures and their interactions. An essential element of this discipline is the repeated testing of hypotheses.
The periodic table, developed by chemist Dmitri Mendeleev, categorizes elements based on their chemical reactivity. Atoms can form chemical bonds with each other to create compounds. Elements combine in predictable ways, and those combinations can be predicted from the atomic structure. Inorganic chemistry deals with substances containing metal elements, whereas organic chemistry studies carbon-based compounds.
Physics
Physics is the science of matter and energy. Its major goal is to understand everything within the natural universe, including all physical matter and energy. Physics also includes all the phenomena related to space and time which we call the cosmos. In essence, it provides an intellectual framework for interpreting nature, from the smallest particle to the largest galaxy.
Physics considers what happens when physical systems interact. For instance, objects may appear to move because they were hit, heated up, cooled down, magnetized, or charged. Understanding the laws of physics helps us predict how real physical systems will behave under given conditions.
Subfields
There are four main branches of classical physics: mechanics, electromagnetism, thermodynamics, and quantum mechanics. Each branch has further specialized areas, such as acoustics, fluid dynamics, solid state physics, and nuclear physics. Additionally, there is modern physics, which includes branches like particle physics, cosmology, relativity, and statistical mechanics.
In summary, science, particularly the disciplines of Chemistry and Physics, plays a crucial role in our understanding of the world. Through rigorous experimentation and theory development, scientists continue to explore new concepts and refine existing ones, ultimately leading to advancements in technology and human knowledge.
