3. Logic

In general, you use 'logic' to work out whether doing something causes the result to be 'True' or 'False'.

Consider the painful experiment below:

'If I stick my finger in boiling water then I will burn my finger'.

Is this a True statement?

You work out the truth of this statement by applying some known rules such as:

Rule 1: I am human
Rule 2: Human finger + boiling water = burnt finger.

Therefore the two rules are applied one after another. 'I am human' (True), 'I've
stuck my finger in boiling water (True) therefore (logically) my finger will be burnt

It is very important to note that normal logic does not have anything in-between,
there is no 'slightly true' or 'slighty false' result.

It is either True or False.

The early designers of computers quickly realised that logic can be used within a computer to work out problems. After all, computer data is either 1 (Logic True) or 0 (Logic False).
