World –> Sign: ‘Science’ Products
As indicated by the above model, science & technology/engineering processes are reciprocal – each influencing the other – and, so, have similarities. Nevertheless, it seems helpful to think of them as being somewhat different – with ‘science’ mainly focused on generating products like laws & theories, as explained in the video at right/below. For example, a solid (e.g., ice) can change ‘state’ to a liquid (e.g., liquid water) and then a gas (e.g., invisible water vapour in the air), which can be explained in terms of the ‘particle theory‘ – in that, for example, in liquid –> gas changes, particles can separate from each other as they they gain heat energy.
