Types of Systems Types of Systems Dynamical systems come in all shapes and sizes. Quantifying weather systems involves an enormous number of measurements. We would have to know the air pressure, temperature and humidity at every point in the earth's atmosphere. Strictly speaking, this is impossible, so in practice sample measurements are taken and the rest are guessed.
Some systems involve only a single variable.
But even in the simplest of systems, we often find chaos. It is vital to understand that complex and erratic behaviour in a system need not be due to either the presence of many variables outside influences Even very simple systems can behave chaotically because of their very nature . For example, it makes sense to record related animal populations after each breeding season. Our pendulum was an example of such a system. Such systems are much harder to study and chaos is much harder to depict.
