Physics is playing an continually increasing role in the health sciences, but does have a significnt historical role as well. From the discovery of x-rays to the invention of magnetic resonance imaging, physics has led to the development of a host of technologies that permit the doctor to see inside the human body. Nevermind the fact that understanding the physics of optical systems allows lenses to be created which allow both patient and doctor to see. The emergence of lasers now allows for surgeries such as Lasik. Related to diagnostics and protection, physics is leading to the invention of a host of sensor technologies that allow for the analysis of blood, urine, and breath for various physiological parameters (proteins, toxins, etc.). Not only do these biosensors have applicability in the realm of clinical diagnostics, but they are becoming important tools in homeland defense. There are numerous examples of physics in health sciences, and what I have mentioned are only a few. In the coming years physicists will seek to explain more biological phenomena in the same way they formulated a quantum mechanical understanding of chemistry in the early twentieth century.

Physics (from the Greek, φύσις (phúsis), "nature" and φυσική (phusiké), "knowledge of nature") is the science concerned with the discovery and understanding of the fundamental laws which govern matter, energy, space and time. That is, physics deals with the elementary constituents of the Universe and their interactions, as well as the analysis of systems which are best understood in terms of these fundamental principles. Physics is a study of the inorganic, physical world, as opposed to the organic world of biology, physiology, etc. [1] Physics overlaps with chemistry concerning the electro-chemical interactions of substances.\nCentral theories\n\nWhile physics deals with a wide variety of systems, there are certain theories that are used by all physicists. Each of these theories were experimentally tested numerous times and found correct as an approximation of nature (within a certain domain of validity). For instance, the theory of classical mechanics accurately describes the motion of objects, provided they are much larger than atoms and moving at much less than the speed of light. These theories continue to be areas of active research; for instance, a remarkable aspect of classical mechanics known as chaos was discovered in the 20th century, three centuries after the original formulation of classical mechanics by Isaac Newton (1642–1727). These "central theories" are important tools for research into more specialized topics, and any physicist, regardless of his or her specialization, is expected to be literate in them.\n\n    * Classical mechanics is a model of the physics of forces acting upon bodies. It is often referred to as "Newtonian mechanics" after Newton and his laws of motion. Classical mechanics is subdivided into statics (which models objects at rest), kinematics (which models objects in motion), and dynamics (which models objects subjected to forces). See also mechanics.\n\n    * Electromagnetism, or electromagnetic theory, is the physics of the electromagnetic field: a field, encompassing all of space, which exerts a force on those particles that possess the property of electric charge, and is in turn affected by the presence and motion of such particles. Electromagnetism encompasses various real-world electromagnetic phenomena.\n\n    * Thermodynamics is the branch of physics that deals with the action of heat and the conversions from one to another of various forms of energy. Thermodynamics is particularly concerned with how these affect temperature, pressure, volume, mechanical action, and work. Historically, it grew out of efforts to construct more efficient heat engines — devices for extracting useful work from expanding hot gases.\n\n    * Statistical mechanics, a related theory, is the branch of physics that analyzes macroscopic systems by applying statistical principles to their microscopic constituents and, thus, can be used to calculate the thermodynamic properties of bulk materials from the spectroscopic data of individual molecules.\n\n    * Quantum mechanics is the branch of mathematical physics treating atomic and subatomic systems and their interaction with radiation in terms of observable quantities. It is based on the observation that all forms of energy are released in discrete units or bundles called quanta. Quantum theory typically permits only probable or statistical calculation of the observed features of subatomic particles, understood in terms of wave functions.\n\n    * The theory of relativity, or relativity theory, is:\n\n    *\n          o A physical theory which is based on two postulates (1) that the speed of light in a vacuum is constant and independent of the source or observer and (2) that it is impossible to determine ones absolute velocity in any inertial systems and which leads to the deduction of the equivalence of mass and energy and of change in mass, dimension, and time with increased velocity — called also spec

I would get a book like SparkNotes for Physics, a nice small short book with just what you need.\n\nThe language of physics is mathematics. In order to study physics seriously, one needs to learn mathematics that took generations of brilliant people centuries to work out. Algebra, for example, was cutting-edge mathematics when it was being developed in Baghdad in the 9th century. But today it's just the first step along the journey.\nAlgebra\n  Algebra provides the first exposure to the use of variables and constants, and experience manipulating and solving linear equations of the form y = ax + b and quadratic equations of the form y = ax2+bx+c.\nGeometry\n  Geometry at this level is two-dimensional Euclidean geometry, Courses focus on learning to reason geometrically, to use concepts like symmetry, similarity and congruence, to understand the properties of geometric shapes in a flat, two-dimensional space.\nTrigonometry\n  Trigonometry begins with the study of right triangles and the Pythagorean theorem. The trigonometric functions sin, cos, tan and their inverses are introduced and clever identities between them are explored.

Modern physics deals mainly with two branches: relativity and quantum mechanics. Relativity, in it's general form, deals with accelerated frames of reference suitable for the study of phenomena related to the outer space.\n\nFrom it came the relativistic mechanics, which is the branch that deals with objects moving at very high constant speeds, which are comparable to the speed of light.\n\nOn the other hand, quantum mechanics is the physics appropriate in the microscopic world(extremely small such as molecules, atoms and electrons), this small world uses the Angstrom as a measuring unit which is 10^-10 m, the quantum mechanics is successful between sizes of 10^-14 m (nucleus) to 10^-7 m.\n\nThere is also the Relativistic Quantum mechanics for both small and fast bodies, and there is the Classical(Newtonian) mechanics for large and slow bodies.

Personally I liked "Physics and Philosophy" and "Physics and Beyond" by Heisenberg.  The latter is Heisenberg's autobiography, but it has some interesting ideas in it.  I also like a multiple volume set of books called  "The World of Physics: A small library of the literature of physics from antiquity to the present" There are a lot of excerpts dealing with historically important discoveries in physics.  It tends to go somewhat easy on the math too.  More recent popular books are "A Brief History of Time" by Stephen Hawking, and "The Elegant Universe" by Brian Greene.

Understanding the scientific method allows us to solve important everyday problems, even problems that arise in the workplace. As a second reason, a lot of people find it interesting and worthwhile besides.

The trouble that most people have with understanding physics is (1) mastering the mathematics needed to set up and solve the problem (2) getting an intuition for the behavior of the systems that you are trying to learn.\n\nSo one way to improve is to make sure you have mastered algebra and calculus. This way you can focus your learning on physics, rather than on math. The second point about developing an intuition has to do with the fact that most of us already have some understanding of rudimentary physics just from our everyday experience in the world. This way when you are trying to solve a new physics problem, you can ask relevant key questions that can guide you toward the right direction.
