The way you walk, when you flip a switch and the lights come on, when you aim a basketball, when you heat up a bowl of seaweed chicken in a microwave oven, even when you ride a bicycle — all these things happen in the way they do because Physics.
Chemistry is the study of matter and energy wait — does this sound familiar? Source: LiveScience. Biology is the study of living things. As long as life is involved, it comes under biology. Biology involves explaining aspects of living things, change in living things, even death. It investigations the evolution of living things, and how living things interact with their environment. This is because no living thing exists in isolation from their environment.
The study of Biology includes: animal behaviour, biochemistry, biotechnology, environmental ecology, genetics, marine biology, and even food and drink safety. Nothing is so cleanly divided. After all, through each of the branches, we study another aspect of life, and what happens around us. Some things are obvious — we take one look, and we can see it. If I push a ball, it moves.
The harder I push it, the further it moves. If the ball is too heavy, I might not be able to move it at all. Some things we never thought possible are being proven possible in very tangible way. Top Posters In This Topic 9 9 21 What makes the job of the chemist different from the job of the physicist? JaKiri Posted January 12, Chemistry deals with the interactions between electron shells.
Obviously, chemistry is a subset of physics. Radical Edward Posted January 12, I agree with MrL. All science a subset of Physics. VendingMenace Posted January 12, Science consists of either Physics, or stamp collecting.
VendingMenace said in post 9 : Refferring to things other than Physics as stamp collecting shows an inability to appreaciate anything other than what you do. If we lived about years ago Skye Posted January 12, VendingMenace said in post 9 : No of course this saying is a bit belittleing. Posted January 13, Im 6 foot 4. Try and belittle me. JaKiri Posted January 13, YT Posted January 13, YT said in post : and when you use a battery to make an electro magnet in the Lab, you exploit chemical principals and so I restate that chem and physics go hand in hand.
Radical Edward Posted January 13, Radical Edward said in post : consider two sets, one set A is the set of all the things you can do using physics.

Physics studies many other things than just atoms, electrons, and molecules. Or to say the least, it studies other aspects of matter than just their composition from atoms or molecules when it studies heat, it's about the energy carried by atoms but it is interested in completely different properties than just the arrangement of atoms inside molecules.
Chemistry studies very specific things: the phenomena in which atoms in molecules reorganize into different molecules reactions and the structure of these molecules as an organized collection of atoms. It studies it because it wants to convert materials, liquids, or solutions to others, usually because these materials or compounds have some applications.
It is a modern scientific version of alchemy that began with this research in not-quite-scientific framework. While chemistry is very advanced today, it doesn't use mathematics too much.
Physics is about the research of all aspects of Nature that are sufficiently "simple" or "fundamental" so that we may describe their behavior by accurate enough mathematics and the laws that govern this observable behavior may be translated to very accurate mathematical equations, too.
It's a different motivation, different strategy, and different methodology. When systems become too complex or "composite", such as some particular complicated molecules, we usually don't expect physics to study these things that fail to be fundamental although they may have very important applications in industry or chemistry. In the case of atoms, physics still studies the objects using the traditional physical concepts such as position, velocity, acceleration, forces, energies — applied to electrons, atoms, and molecules.
It actually wants to translate all these things to real numbers. We find out that to do so, classical mechanics must be replaced by quantum mechanics and deal with things like "wave functions" instead of positions but it still deals with real or complex functions of real or complex variables which include time. Chemistry is much more practically oriented discipline that mostly studies the qualitative differences between compounds and how they change in the reactions. Of course, there is a boundary between physics and chemistry.
It is probably not easy to divide the subdisciplines that exist near the boundary but they include physical chemistry, quantum chemistry, chemical physics, and so on. These terms are actually different from each other and the practitioners may talk at length when they're working on physical chemistry and chemical physics but at the end, it's usually the same researchers, anyway.
When it's physics, it's about the mathematical laws of Nature which matter. When it's chemistry, it's about the compounds and reactions.
Just to give you a simple analogy, physics is like "constitution" of a nation. Chemistry is a set of "laws", governing one particular types of affairs of the nation. Any law of chemistry must be "constitutionally valid".
Please don't bring amendments here, though Physics is the "foundation". In rough terms at the very fundamental level, it mostly deals with energy, mass, and electric charge. As mentioned by "Lubos", it studies both things at atomic scale, and things at galactic scale. Its ultimate aim, though not everyone would agree with that is to find an equation that would explain everything. They've a name for it. Theory of Everything.
