Lasers make magnets behave like fluids

For years, researchers have pursued a strange phenomenon: When you hit an ultra-thin magnet with a laser, it suddenly de-magnetizes. Imagine the magnet on your refrigerator falling off.

Abundance of information narrows our collective attention span

The negative effects of social media and a hectic news cycle on our attention span has been an ongoing discussion in recent years—but there's been a lack of empirical data supporting claims of a 'social acceleration.' A ...

New method inverts the self-assembly of liquid crystals

In liquid crystals, molecules automatically arrange themselves in an ordered fashion. Researchers from the University of Luxembourg have discovered a method that allows an anti-ordered state, which will enable novel material ...

Going with the flow: how faecal bacteria spread in streams

Faecal bacteria – bacteria that are present in the digestive system of humans and animals – are known to contaminate waters. They can sometimes be a health hazard. Little research has been conducted into the spread and ...

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.
