Physics and it's connection to other sciences
From Teach And Discover Wiki
Physics is in some senses the oldest and most basic pure science; its discoveries find applications throughout the natural sciences, since matter and energy are the basic constituents of the natural world. The other sciences are generally more limited in their scope and may be considered branches that have split off from physics to become sciences in their own right.
One trend in all fields of science over the past century has been to explore ways in which the five basic sciences (physics, chemistry, astronomy, biology, and earth sciences) are related to each other. This has led to another group of specialized sciences in which the laws of physics are used to interpret phenomena in other fields. Astrophysics, for example, is a study of the composition of astronomical objects, such as stars, and the changes that they undergo. Physical chemistry and chemical physics, on the other hand, are fields of research that deal with the physical nature of chemical molecules. Geophysics deals with the physics and chemistry of Earth's dynamic processes. Biophysics, as another example, is concerned with the physical properties of molecules essential to living organisms.
From the world of the very large to the world of the very small, the laws of physics basically dictate what can and cannot be done. What we know of physics today helps each of the other sciences and their realms of study to recognize the bounds that are set. Whether you are studying the universe around us (astrophysics), the galaxy (astronomy), the solar system (planetology), the planet (geology), the entity (anatomy), the cells (biology), the molecules (chemistry), or the atom (physics), everything either begins or ends with physics.

The Fundamental Science
Physics is the "fundamental science" because the other natural sciences (biology, chemistry, geology, etc.) deal with systems that obey the laws of physics. The physical laws of matter, energy, and the forces of nature govern the interactions between particles (such as molecules, atoms, or subatomic particles).
