مقدمة من الكتاب :

People studying physics sometimes try to learn a lot of laws, principles and rules by
memorising a lot of equations. There are actually only a few central ideas in physics which
appear in many different forms. These short workshops will look at a few of these basic ideas,
in particular conservation principles and Newton’s laws.

These principles and laws are often treated as articles of faith – things that are always obeyed
and always true. In fact the laws of physics are reasonable working theories, that have been
shown to work enough times, and never been shown to not-work, that we accept them as true.
In fact it is impossible to prove that they are true. Any law or theory can be disproved, but it
cannot be proved, that is the nature of a scientific theory. This is not to devalue the laws and
theories of physics – to say, “well, it’s just a theory, its no better than any other theory” is
missing the point. Scientific theories are useful – they help us understand our environment and
give us predictive power, and they can be applied to give us useful technology. Many people
find the quantum theory strange and unbelievable – yet all our modern technology, from
transistors to computers and cellular phones is based on quantum theory.

In these workshops we will look at some of these basic laws and discuss ways they can be
taught /learnt in the classroom. The first workshop will deal mainly with conservation
principles, while the second will look at Newton’s laws and forces. These two ideas – forces
and conservation – are related, and this relationship will be stressed throughout.
