Study Notes
Science Overview
Science is a broad field of study that encompasses many different disciplines dedicated to understanding our world through observation and experimentation. Three major branches of science are biology, chemistry, and physics. Each of these areas focuses on specific aspects of how things work and their interactions with one another. Let's take a closer look at each branch.
Biology
Biology is the scientific discipline focused on living organisms. It seeks to understand the structure, function, growth, reproduction, adaptation, evolution, distribution, and abundance of all forms of life. This can range from studying individual cells and molecules, to entire ecosystems.
One key area within biology is molecular biology, which deals with the analysis of biological systems at the level of atoms and molecules. Genetics is also a critical aspect of biology, dealing with heredity and the variation of inherited traits both between species and individuals. Another important concept is ecology, which examines relationships among living organisms, including competition, predation, parasitism, mutualism, cooperation, symbiosis, population dynamics, and community structures.
Chemistry
Chemistry is the scientific discipline concerned with the composition, properties, behavior, and changes of matter. At its most basic, it involves the organization and manipulation of atoms and molecules to create chemical compounds. However, modern chemistry includes much more advanced concepts, such as quantum mechanics, thermodynamics, material science, and organic synthesis. These fields all have practical applications in medicine, agriculture, industry, and technology.
Another important area within chemistry is physical chemistry, which deals with the interaction between energy and matter. Analytical chemistry concerns itself with measuring quantities of substances and determining their identities. Organic chemistry focuses on carbon-based compounds, while inorganic chemistry studies everything else. All of these subfields overlap and influence each other, making chemistry a complex and diverse subject.
Physics
Physics is the fundamental science discipline concerned with the nature and properties of matter, energy, space, time, and their interactions. In essence, it investigates the behavior of objects when they interact with one another in motion, force, or action. Newtonian physics looks at how gravity affects movement of bodies; quantum physics explores smaller particles such as electrons, protons, neutrons, and photons. Astronomy falls under this umbrella too, because it observes celestial phenomena using principles derived from physics.
In addition, there are several specialized areas of physics: acoustics (sound), optics (light), geophysics (earth), meteorology (weather), oceanography (oceans), planetary sciences, seismology (earthquakes), astrogeology (space exploration), astronautics (spacecraft design), and nuclear physics. Most physicists focus on just one specialty, although some researchers have expertise across multiple subjects.
These three disciplines are interconnected, with cross-pollination happening constantly. For instance, chemists may use techniques developed by physicists, and biologists benefit from advances made in materials science. Understanding the connections between various branches helps scientists make breakthrough discoveries and advance knowledge in all areas of science.
