Best Physical Science and Engineering Courses Online [2024] | Coursera (2024)

Physical science explains all that we know about the workings of the natural world, from the deepest core of Earth to the farthest reaches of space - and from microscopic atoms to the entire atmospheric system of the planet. This truly vast topic encompasses a diverse range of more specific subfields including chemistry, geology, astronomy, physics, oceanography, and more. Each of these disciplines within the physical sciences has a different approach to studying the individual elements and processes that characterize their particular area of focus.

Many people go into the physical sciences out of a simple love for the material. Knowing the way the geology of the planet has evolved over billions of years, or understanding the magical-seeming processes that drive chemical reactions, can be fascinating and inherently satisfying. However, the physical sciences are also vital to understanding and solving critically important challenges faced by society.

For example, geology is essential to natural resource exploration, guiding the effort of mining companies to find raw materials like coal and copper. Atmospheric science is foundational to our understanding of climate change, explaining how carbon dioxide emissions from burning fossil fuels are responsible for rising temperatures - and estimating how much (and how soon) we need to cut these emissions to preserve a habitable planet. And both physics and astronomy are necessary for space exploration, potentially charting new paths forward for the future of humanity.

Each of these fields may be quite different and distinct from each other, but together they seek to describe all of the interrelated aspects of our physical world. And, while we’ve come a long way in this knowledge, there is still much that we don’t yet understand - and thus many exciting, world-changing new discoveries to be made by experts in all of the physical sciences.‎

The career paths available to those with an education in the physical sciences are just as varied as the different areas of study within this vast field. Some areas with largely scientific applications tend to lead towards jobs in academia or education. For instance, astronomy majors with bachelor’s degrees often become high school teachers or work at planetariums, while many others continue to graduate school to pursue a career in research answering questions about the extraterrestrial universe.

By contrast, physics is an example of a field that can lead to a wide range of jobs both inside and outside of academia. If you want to do laboratory research at cutting-edge facilities like CERN (the European Organization for Nuclear Research), you can aspire to become a particle physicist and study the behavior of the subatomic world. On the other hand, if you want to solve more practical problems on a (much) larger scale, physics is also highly useful for careers designing buildings and other structures as an engineer.

Geoscience backgrounds can also lead to a variety of non-academic careers, depending on which area of this field you are interested in. Geologists are employed by mining and drilling companies to help determine where to find valuable resources under the earth’s surface, and experience in this area can also lead to work providing insights to various companies in finance and as an energy consultant. Specialists in hydrology can find work studying the composition of bodies of water for environmental agencies or advocacy groups.‎

Online courses are a great way to learn about topics in physical science and engineering, giving you the opportunity to start a new direction in your education as a beginner or add to your existing knowledge as a more advanced learner. If you want to learn about the natural world, you can find courses in geography, geology, oceanography, and more. If your interests are more in physics and engineering, you can take both general introductory courses as well as more specialized courses in topics like material science, engineering, or even nanotechnology.

No matter what your area of interest, Coursera lets you learn from top-ranked schools, ensuring you don’t have to sacrifice the quality of your education if you want to learn online. Institutions offering courses in physical science and engineering on Coursera include the University of Virginia, Georgia Institute of Technology, and the University of Colorado Boulder. And, despite learning the same material and from the same instructors as on-campus students, you’ll pay a significantly lower tuition and can complete your coursework on a flexible schedule. ‎
