You don’t need to be a science buff to appreciate this discussion. So if you’re ready to delve into the exciting worlds of chemistry and physics and discover which one is “harder,” let’s get started!
The Fundamental Differences Between Chemistry and Physics
Chemistry and Physics are Separate Fields of Study
While both chemistry and physics deal with the fundamental principles of matter and energy, they are separate fields of study. According to Josh Bloom, a chemist and senior director of chemical and pharmaceutical sciences at the American Council on Science and Health, “The two disciplines use different tools to answer very different questions.”
Chemistry Deals with Matter and Its Compositions, While Physics Deals with Energy and Its Properties
A major difference between chemistry and physics is their respective focuses. Chemistry deals mainly with the properties, compositions and reactions of matter. Physicists, on the other hand, focus on understanding the behavior and properties of energy or particles. The Director of the School of Physics and Astronomy at the University of Minnesota explains: “Chemistry concerns itself with how electrons jump around among atoms, whereas in physics that kind of problem gets left behind early on. Instead, physicists look at more complicated phenomena.”
Chemistry Focuses on Reactions and Molecules, While Physics Focuses on Forces and Particles
The practical applications of chemistry and physics also differ. Chemists typically work with molecules, studying chemical reactions and molecular structures to create new compounds and materials. On the other hand, physicists tend to work with larger systems like subatomic particles or forces such as gravity. They study the origins of the universe or investigate theories of everything.
Chemistry and Physics Have Different Approaches to Understanding the World
The main difference between these two fields lies in their approach to investigating phenomena within the material world. Debra Rolison, a physical chemist working for the US Naval Research Laboratory explains that, “Chemists are trained to go from a starting product to a finished product systematically, making iterative changes as needed along the way.” In contrast, physicists are more theoretical. “They use mathematics first, then go about testing their theories with experiments,” she says.
“The laws of physics and the laws of chemistry may look similar because they’re both about natural stuff in the universe, but in terms of understanding how things happen at this material world level, there’s a tremendous difference between what a chemist does day-to-day to tackle problems and understand mechanisms versus what a physicist is doing” – Debra Rolison
In essence, while both disciplines explore related subjects, they take different approaches that require distinct sets of expertise.In conclusion, neither field is inherently harder than the other; it all depends on your interests and strengths. As Josh Bloom emphasizes: “You don’t have to choose based on preconceived notions or perceptions of what’s easier or harder.” What matters most is finding a subject area you’re passionate about, and pursuing it wholeheartedly.
The Complexity of Physics and Its Theories
Understanding the Fundamentals of Physics Takes Time and Effort
Physics is the science of matter and energy and its interactions in the physical world. Understanding physics requires a deep understanding of fundamental concepts such as force, momentum, motion, and time. These concepts may seem straightforward at first glance but deeper analysis reveals that they are anything but simple.
Students who study physics have to put in significant time and effort to truly understand these complex concepts. They must be willing to spend long hours poring over textbooks and lectures to grasp even the most basic principles of physics. Without putting in this time and effort, it can feel impossible to really grasp the complexity of this subject.
Theories in Physics Can Be Difficult to Understand and Apply
One of the reasons why physics is so complex is because many of its theories are abstract and not easily applicable to real-world situations. For example, quantum mechanics, one of the most important theories in modern physics, describes the behavior of subatomic particles and their interactions with electromagnetic radiation. However, quantum mechanics is notoriously difficult to understand and apply, even for experienced physicists.
This difficulty arises from the fact that much of quantum mechanics involves mathematical abstractions that are not easy to visualize or relate to in everyday life. As a result, applying these theories practically takes an advanced knowledge of mathematics.
Physics Involves Complex Mathematical Calculations and Formulas
As mentioned above, many theories in physics involve complex mathematical calculations and formulas. To fully comprehend what’s going on, students will need to gain proficiency in calculus, linear algebra, and other mathematical disciplines. This requirement makes physics tougher than chemistry as solving equations is more important which requires heavy use of maths.
Unfortunately, for many students, math is not a subject that comes naturally. This means that in addition to learning the concepts of physics, they also have to put in significant time and effort into understanding the math behind each concept.
“Study hard what interests you the most in the most undisciplined, irreverent, and original manner possible.” – Richard Feynman
When compared with chemistry, it can be said that physics is harder because while both subjects require knowledge of mathematics, the formulas involved in physics tend to be more complex than those encountered in chemistry. The theories in physics are often abstract and not easily applicable to real-world situations, making them even more challenging to understand. To really understand physics, students must be willing to put in the time and effort to learn both the underlying concepts and the mathematical formulas involved.

“The advance of chemistry has not only enriched us intellectually but has given practical benefits to mankind.” -Jawaharlal Nehru
Chemical reactions are all around us, from the rusting of iron to the baking of bread. By knowing which reactants will produce which products under certain conditions, chemists can create better performing and longer-lasting products. For example, through their understanding of chemical reactions, chemists were able to create synthetic rubber to replace natural rubber during World War II when supply lines were cut off.
Chemistry Involves the Study of Molecules and Their Structures
At its core, chemistry involves the study of molecules and their structures. Chemists study everything from atoms and ions to larger organic molecules like proteins and DNA. Researchers use a range of sophisticated techniques to investigate these molecules, including x-ray diffraction, mass spectrometry, and nuclear magnetic resonance spectroscopy (NMR).
A key aspect of chemistry is determining the three-dimensional structure of molecules, as this dictates their properties and interactions with other molecules. Determining the shape of molecules is essential for designing new drugs, for example.
Chemistry Can Help Explain the Properties of Matter
Through chemistry, we can better understand the properties of matter and how they are related to their molecular structure. For example, chemists know that a molecule’s size, shape, and polarity dictate whether it will dissolve in water or not. Similarly, by understanding the chemical structures of pigments in plants, scientists have been able to create artificial photosynthesis technologies that could one day help generate clean energy from sunlight.
“Chemistry is the science of substances; biochemistry is the science of life.” -John T. Dalton
In addition, chemistry has helped us develop new materials with unique physical and chemical properties. By carefully selecting different types of atoms and bonding them together in specific ways, researchers have created plastics with varying levels of strength and flexibility, metals with increased corrosion resistance, and ceramics with improved heat resistance.
Chemistry Has a Wide Range of Applications in Everyday Life, from Medicine to Agriculture
