What is the purpose of biophysics?
Biophysics has been critical to understanding the mechanics of how the molecules of life are made, how different parts of a cell move and function, and how complex systems in our bodies—the brain, circulation, immune system, and others— work..
What math is in biophysics?
The student should know the basics of multivariable calculus, in particular, vector calculus and curves in space and Fourier series. Also the student should be familiar with the basics of linear algebra: vectors, matrices, eigenvalues of matrices. Some knowledge of complex numbers is helpful..

Population biology is certainly the oldest area of biology where mathematics has been used. Speaking usually of large populations, partial differential equations (PDE) play a natural role.
Biophysics represents a science on fundamental laws underlying the structure, functioning, and development of living systems.
Mathematical models of the processes in biological membranes comprise a significant portion of mathematical biophysics. Existing models are mostly presented by
Models of the interaction between the species: Mathematical models governed by differential or finite- difference equations describing the spatio-temporal
Are biochemical and electrophysiological models based on laws?
Both the biochemical models and the electrophysiological models we study are based on laws:
the law of mass action and Ohm’s law. We begin by giving some biological preliminaries, and then we explain the laws and consider them critically to determine when they apply in the cellular environment.
How do we build a biophysical model?
Let us begin by looking at the types of models we will build. Biophysical models use the underlying physiology to try to reproduce the known data on the system as a whole. In building this kind of model, we take the parts, put them together, and see if they are sufficient to reproduce the known system behaviors.
What can I do with a degree in biophysics?
Theoretical work developing models in statistical and mathematical physics to understand aspects of population genetics and eco-evolutionary dynamics. Biophysics at Stanford is pursued across a range of departments and schools, including:
Physics
Applied Physics and Bioengineering.
What is the basic principle in forming equations to model biochemistry?
The basic principle in forming equations to model biochemistry is the law of mass action. This states that the rate of any reaction is proportional to the concentrations of the reactants (we denote concentrations by ). Thus, if A and B bind together to form a complex that we denote AB, we write this reaction as where k is a rate constant.
Biophysics equations
The Avrami equation describes how solids transform from one phase to another at constant temperature. It can specifically describe the kinetics of crystallisation, can be applied generally to other changes of phase in materials, like chemical reaction rates, and can even be meaningful in analyses of ecological systems.
Expression of the ionic flux across a cell membrane
The Goldman–Hodgkin–Katz flux equation describes the ionic flux across a cell membrane as a function of the transmembrane potential and the concentrations of the ion inside and outside of the cell. Since both the voltage and the concentration gradients influence the movement of ions, this process is a simplified version of electrodiffusion. Electrodiffusion is most accurately defined by the Nernst–Planck equation and the GHK flux equation is a solution to the Nernst–Planck equation with the assumptions listed below.
Equation used for physiological interfaces, polymer science, and semiconductors
The Poisson–Boltzmann equation is a useful equation in many settings, whether it be to understand physiological interfaces, polymer science, electron interactions in a semiconductor, or more. It aims to describe the distribution of the electric potential in solution in the direction normal to a charged surface. This distribution is important to determine how the electrostatic interactions will affect the molecules in solution. The Poisson–Boltzmann equation is derived via mean-field assumptions. From the Poisson–Boltzmann equation many other equations have been derived with a number of different assumptions.
Mathematical description of fluid movements
The Starling principle holds that extracellular fluid movements between blood and tissues are determined by differences in hydrostatic pressure and colloid osmotic (oncotic) pressure between plasma inside microvessels and interstitial fluid outside them. The Starling Equation, proposed many years after the death of Starling, describes that relationship in mathematical form and can be applied to many biological and non-biological semipermeable membranes. The classic Starling principle and the equation that describes it have in recent years been revised and extended.
Relation between temperature and the equilibrium constant of a chemical reaction
The Van 't Hoff equation relates the change in the equilibrium constant, texhtml >Keq, of a chemical reaction to the change in temperature, T, given the standard enthalpy change, texhtml >ΔrH⊖, for the process. The subscript mwe-math-element> means reaction and the superscript mwe-math-element> means standard. It was proposed by Dutch chemist Jacobus Henricus van 't Hoff in 1884 in his book Études de Dynamique chimique.
The McKendrick–von Foerster equation is a linear first-order partial differential equation encountered in several areas of mathematical biology – for example, demography and cell proliferation modeling; it is applied when age structure is an important feature in the mathematical model. It was first presented by Anderson Gray McKendrick in 1926 as a deterministic limit of lattice models applied to epidemiology, and subsequently independently in 1959 by biophysics professor Heinz von Foerster for describing cell cycles.
