There are a number of interesting areas that are in development:\n\nThese are in no particulkar order:\n\n1. Supersymmetric String Theory. Mathematicians are trying to pull together a cohesive set of equations that prove the existence of up to 26 alternate dimensions. It is considered one of the most promising candidate theories of quantum gravity. Unlike bosonic string theory, it is the version of string theory that incorporates fermions and supersymmetry.  The deepest problem in theoretical physics is harmonizing the theory of general relativity, which describes gravitation and applies to large-scale structures (stars, galaxies, super clusters), with quantum mechanics which describes the other three fundamental forces acting on the microscopic scale.\n\n2. Collabroative Filtering. This has been on the rise in recent years. It's basically a set of equations that determine group behavior. The most common application is an attempt to predict an individual buyers tastes based on what they buy and other people that purchase the same material. Amazon.com are already using a version of Collaborative Filtering. More recently, collaborative filtering has been used in e-learning to promote and benefit from students' collaboration.\n\n3. Genetics, Bioinformatics, Biostatistics. There is a lot of emphasis on mathematical prediction analysis, particurly in the field of genetics: the statistical analysis of the effects of germs, viruses on immune cell diversity; developing methods to predict the structure and/or function of newly discovered proteins and structural RNA sequences; clustering protein sequences into families of related sequences and the development of protein models; aligning similar proteins and generating phylogenetic trees to examine evolutionary relationships. Biostatistics is the application of statistical techniques to scientific research in health-related fields, including medicine, biology, and public health, and the development of new tools to study these areas.\n\n4. Number Theory. This is always a strong area as there never seems to be a shortage of research candidates: prime number theory, probabilistic number theory, elliptic curves, Galois module structure, deformations of Galois representations, Iwasawa theory, Wiles' proof of Fermat's Last Theorem, Ramanujan's Notebooks, modular forms, partition theory, special functions, elliptic functions (elliptic integrals), geometry of numbers, Diophantine approximation, arithmetic functions, sieves, transcendence and irrationality, continued fractions, q-series, and coding theory.\n\n5. Logic: Axiomatic Systems and Set Theory. Set Theory is the mathematical science of the infinite. It studies properties of sets, abstract objects that pervade the whole of modern mathematics. The language of set theory, in its simplicity, is sufficiently universal to formalize all mathematical concepts and thus set theory, along with Predicate Calculus, constitutes the true Foundations of Mathematics. As a mathematical theory, Set Theory possesses a rich internal structure, and its methods serve as a powerful tool for applications in many other fields of mathematics. Set Theory, with its emphasis on consistency and independence proofs, provides a gauge for measuring the consistency strength of various mathematical statements. There are four main directions of current research in set theory, all intertwined and all aiming at the ultimate goal of the theory: to describe the structure of the mathematical universe. They are: inner models, independence proofs, large cardinals, and descriptive set theory.

Yes. But it is very difficult to explain as the study of bio mechanics is in the early stages. As everyone knows it is possible to stimulate the brain by either electrical or chemical means. Our brain is active both electrically and chemically. I wish you pursue this line of study as it has huge potential.

In practice most of these branches of physics employ both theorists and experimentalists. Occasionally an individual wears both hats.\n\nCondensed Matter Physics \nThis is the study of matter when there are large numbers of particles in close proximity. Ordinary solids are the most common example. This research lead to the first transistor and to today's high capacity storage media. But the field also includes many esoteric forms of matter, from Nutronium (the substance of neutron stars) to matter confined to one or two dimensions. Recent work has produced samples numbering in the tens of thousands of atoms that all behave according to a single wave function (the atoms have lost their individual identities). These collections are called Bose-Einstein Condensates (BEC) and form a new category of matter. \nAtomic and Molecular Physics \nIndividual atoms or small groups of atoms are the focus in this field. Some researches use single trapped atoms to make extremely precise measurements to confirm theories about Quantum Mechanics or Relativity. Others are exploring the interaction between atoms (or molecules) or the interaction between light and atoms. Lasers and laser physics are an important part of this research area. \nNuclear Physics \nAs the name implies, this field examines the nucleus of the atom. While the composition of the nucleus is understood for all atoms and their isotopes, the arrangements and interactions of the nuclear constituents is still a rich field of study. Nuclear physics includes the fission and fusion reactions that provide nuclear power, as well as the nuclear synthesis process that fuels the sun and other stars. \nHigh Energy Particle Physics \nThis is where the theories about the fundamental structure of nature are devised. They are then tested at high energy accelerator laboratories and in the study of cosmic rays. Theories about the smallest particles and the largest structures in our universe have become linked by the Big Bang Theory. Many High Energy Physicists also do work in Cosmology. \nMathematical Physics \nHistorically physics and mathematics grew up together, each field pushing the other into new realms. The mathematical physicist works on the border between math and physics to help us find a rigorous description of nature. Some of the most subtle and profound ideas in physics were created here. \nPhysics Education Research \nThis is a relatively new field in physics departments. The practitioners are physicists who observe students learning physics and examine the difficulties encountered. Their work is changing the face of the college physics course nationwide. \nInterdisciplinary research \nA growing number of departments support degree candidates who want to straddle two disciplines in their research. Topics like these at UIUC are indicative of the programs available. Here again your best search strategy is to visit the graduate programs, select a particular physics department, and search that site for research topics.

Yes.  Physics is the science of the physical world, of natural bodies.  Physicians are those who heal the natural body of the person.

Anything in the science industry. Mechanical engineering (hopefully you like math as well) and other kinds of engineering. Astronomy. Definitely astronomy. Or just stick to the pure physics and apply to grad school for it.

What you're describing is called the 'grand unified theory,' or GUT. There are four known fundamental forces in nature that literally control everything--gravity, electromagnetism, the weak nuclear force, and the strong nuclear force. Science has been successful in uniting all of these except gravity.

biochemistry\nClick to learn more...\nscience concerned chiefly with the chemistry of biological processes; it attempts to utilize the tools and concepts of chemistry, particularly organic and physical chemistry, for elucidation of the living system. The science has been variously referred to as physiological chemistry and as biological chemistry. Molecular biology, a term first used in 1950, is used to describe the area of research, closely related to and often overlapping biochemistry, conducted by biologists whose approach to and interest in biology are principally at the molecular level of organization. The related field of biophysics brings to biology the techniques and attitudes of the physicist. Cell biology is concerned with the organization and functioning of the individual cell and depends greatly on biochemical techniques. As the study of life forms demonstrated similar or even identical processes occurring in widely divergent species, it has taken the biochemist to unravel the underlying chemical basis for these phenomena. Biochemists study such things as the structures and physical properties of biological molecules, including the proteins, the carbohydrates, the lipids, and the nucleic acids; the mechanisms of enzyme action; the chemical regulation of metabolism; the molecular basis of genetic expression; the chemistry of vitamins; chemoluminescence; biological oxidation; and energy utilization in the cell. The study of the chemistry of the immune response offers the possibility of treatment and cure for such diseases as AIDS and lupus.\n\n   1.   The study of the chemical substances and vital processes occurring in living organisms; biological chemistry; physiological chemistry.\n   2. The chemical composition of a particular living system or biological substance: viral biochemistry.

The unifying theory within biology is considered by most to be the theory of evolution, in reality there are several theories that can be considered unifying: the cell theory, the theory of evolution, gene theory, and the theory of homeostasis.\n\nIf this is for homework, I would guess that your teacher or whoever created the worksheet you're doing for homework is looking for the theory of evolution.
