There are a lot of factors to think about before choosing a major. The question, "What are the five sciences?" may be on your mind. The study of natural phenomena is the academic discipline known as "natural science." Physics, chemistry, and biology are the three mainstays of the natural sciences.
The field of study known as physics examines how matter interacts with the rest of the physical universe. It's a cornerstone of the natural world and one of the earliest scientific disciplines. How and why things function on the subatomic, nuclear, and cosmic scales is what physics is all about. It is the foundational discipline upon which the more specialized disciplines of chemistry, biology, and astronomy are built.
It's the foundation of most contemporary technology and helps us create cutting-edge instruments in the lab and hospital. Wind turbines, solar panels, and satellites couldn't exist, nor could X-rays and MRI scans be used to diagnose illness.
To put it simply, chemistry is the study of matter and all of its characteristics and transformations. Chemistry is the study of matter and the compounds formed of atoms, molecules, and ions, including its composition, structure, characteristics, behaviour, and changes when mixed with other substances.
A chemical's atoms can be in a solid, liquid, or gaseous phase. Depending on the conditions of heat and pressure, a wide variety of phases can be found.
Atoms are the building blocks of everything, from pharmaceuticals to foods. Since these atoms are the foundation of chemistry, the study of the subject is crucial to our daily lives.
The study of life, including plants and animals, is known as biology. Botany, zoology, ecology, genetics, marine biology, and medicine are just a few of the fields involved.
Biology is the study of the organization, function, and history of life. It is a field of study that draws from a variety of other disciplines to collect evidence and draw conclusions about how living things work.
Biology encompasses the study of everything from single cells to complex ecosystems. Their work contributes to our knowledge of the diversity and interconnectedness of all forms of life, as well as of the mechanisms that make life possible.
Stars, planets, moons, comets, and galaxies are all subjects of study in astronomy since they exist beyond Earth's atmosphere. Math, physics, and chemistry are employed to shed light on their backstories, evolutionary paths, and potential outcomes.
Similar to other scientific disciplines, astronomy encompasses a wide variety of subdisciplines. Astronomy, cosmology, and heliophysics are all examples of these. Astronomy, one of the earliest scientific disciplines, has profound effects on our modern environment. Ancient cultures relied on astronomical observations to keep track of the seasons and construct calendars, and some people still do this today.
The study of Earth's atmosphere, air, and climate is known as atmospheric science. It takes into account issues that are both difficult to solve scientifically and important for contemporary society.
Chemistry, physics, meteorology, computer modelling, oceanography, geology, and volcanology are only a few of the fields that contribute to our understanding of the atmosphere. Climatology, which studies climate over longer time scales, also has an impact.
From localized climatic systems on a small scale to global climate models, the atmospheric sciences cover a lot of ground. The predictive ability of this and other models is a primary focus of many of PNNL's atmospheric research initiatives.
