Silly talk directed at infants may be more educational than imagined

Many experts on infant learning have suggested that the best way to teach adult language to a tiny baby is to speak as if the infant is another adult – because adult sounds, cadence and tone of voice are what the child ...

Computing told us how close we came to a global pandemic of a drug-resistant flu

We usually consider the scientific study of infection by a virus, bacteria or parasite as the domain of clinical and biomedical research. Surely, the study of a virus invading our cells, hijacking our genetic replication ...

Mathematical simulation of open-heart surgery lends clues to kidney failure

No one can deny that open-heart surgery, where the heart is exposed and the blood is made to bypass it, is one of the most invasive of all medical procedures. Nearly a third of all patients undergoing heart surgery experience ...

Immunity from H1N1 flu vaccine wears off rapidly

H1N1, commonly known as "swine flu," was a new flu strain that appeared in 2009 and quickly spread around the world, killing thousands of people. It is now a regular part of the annual flu season.

Preventing foot ulcers with pressure-predicting model

A new mathematical model to predict the pressure on feet, which could then lead to the prevention of foot ulcers, could be developed thanks to academics at Plymouth University.

New mathematical model may help better define roles of environmental and intrinsic factors in cancer initiation

A mathematical model that takes into account the number of mutations required to initiate a specific type of cancer to estimate mutational activity, rather than cancer initiation, as the elementary event (as reported in two ...

New mathematical model explains variability in mutation rates across the human genome

It turns out that the type, how frequent, and where new mutations occur in the human genome depends on which DNA building blocks are nearby, found researchers from the Perelman School of Medicine at the University of Pennsylvania ...

Neurobiologists characterize nerve cells that detect motion by light changes

The ability to see the direction in which something is moving is vital for survival. Only in this way is it possible to avoid predators, capture prey or, as humans in a modern world, cross a road safely. However, the direction ...

Mathematical model

A mathematical model uses mathematical language to describe a system. Mathematical models are used not only in the natural sciences and engineering disciplines (such as physics, biology, earth science, meteorology, and engineering) but also in the social sciences (such as economics, psychology, sociology and political science); physicists, engineers, computer scientists, and economists use mathematical models most extensively. The process of developing a mathematical model is termed 'mathematical modelling' (also modeling).

Eykhoff (1974) defined a mathematical model as 'a representation of the essential aspects of an existing system (or a system to be constructed) which presents knowledge of that system in usable form'.

Mathematical models can take many forms, including but not limited to dynamical systems, statistical models, differential equations, or game theoretic models. These and other types of models can overlap, with a given model involving a variety of abstract structures.
