Medical physics, a branch of biophysics, is any application of physics to medicine or healthcare, ranging from radiology to microscopy and nanomedicine. For example, physicist Richard Feynman theorized about the future of nanomedicine. He wrote about the idea of a medical use for biological machines (see nanomachines).
By definition, different streamlines at the same instant in a flow do not intersect, because a fluid particle cannot have two different velocities at the same point. However, pathlines are allowed to intersect themselves or other pathlines (except the starting and end points of the different pathlines, which need to be distinct).
Any physics-oriented career position requires at least an undergraduate degree in physics or applied physics, while career options widen with a master's degree like MSc, MPhil, MPhys or MSci. [ 11 ] For research-oriented careers, students work toward a doctoral degree specializing in a particular field.
The field is broadly defined and includes foundations in biology, applied mathematics, statistics, biochemistry, chemistry, biophysics, molecular biology, genetics, genomics, computer science and evolution. Computational biology has become an important part of developing emerging technologies for the field of biology. [3]
Walker is a theoretical physicist and astrobiologist with research interests in the origin of life. [ 1 ] [ 2 ] She seeks to develop new theories of physics to explain what life is, how it emerged, and what signs of life might look like on other planets.
Bowen was able to calculate the forbidden transitions of doubly ionized oxygen to be exactly where the lines had been found. The low probability for collisions in the nebula made it impossible for the oxygen to get from the excited stated to the ground state and so the forbidden transitions were the main path for the relaxation.
Physics is one of the oldest academic disciplines. [5] Over much of the past two millennia, physics, chemistry, biology, and certain branches of mathematics were a part of natural philosophy, but during the Scientific Revolution in the 17th century, these natural sciences branched into separate research endeavors.
Biology is the overall natural science that studies life, with the other life sciences as its sub-disciplines. Some life sciences focus on a specific type of organism. For example, zoology is the study of animals, while botany is the study of plants. Other life sciences focus on aspects common to all or many life forms, such as anatomy and ...
