Why study physics?

This question is probably asked several thousand times a day by children around the world. Physics is undoubtedly an important subject - modern lifestyles are based largely on the advances that the science has brought about. However, I think reasons other than its practical applications are often ignored, and it is these I shall now address.

The first is simply a desire to further our understanding of the universe, for no other reason than a thirst for knowledge. This might seem cliché, but it motivates many people who devote their lives to the study of the sciences. Humans are curious creatures, so it is natural to seek answers to the fundamental questions - “How come we exist?” and “Why do we exist?” to name but a couple. We don’t yet know the answers, and of course it is entirely possible that we never will, but physics gives us a logical and methodical framework with which to address them. It is this that makes physics attractive to those who seek knowledge, understanding and answers, and makes a very good reason to study physics on a long term basis.

For many of us though, a lifetime in research isn’t an option, as we have other interests we want to pursue. So why study physics in this case? One very good reason is that the skills you acquire are readily transferable; it is often said that physics graduates are among the most widely employable due to this. Physics contains a very strong mathematical element (which in itself is useful), but solving problems is more than just mathematics. A “physicist’s intuition” may be a myth, but it is true that physics teaches you to apply a set of rules to an unfamiliar situation, and work out what will happen. Lab work also teaches you more than just physical laws - how to work to a tight schedule, deal with unfamiliar equipment and co-operate with fellow students whilst under pressure. All very useful skills!

Finally, physics is easy! This isn’t of course a reason in itself, however I’m sure a lot of people are put off reading into the subject due to this misconception. In case you aren’t convinced with this assertion, I will try to persuade you. Consider “rocket science”. It is common phrase used to describe anything that is incomprehensible. But in actuality, rocket science itself is surprisingly simple. All we do is apply Newton’s 3rd Law of Motion - that every action has an equal and opposite reaction. A rocket propels hot gases out of the back, and so moves forward - essentially this is all the equations say! (Of course, sometimes you need to take into account air resistance etc., but this also is not hard to write down) At this point we move from the realm of physics to mathematics, and solving these equations can be tricky. However, it is perfectly possible to study and understand physical principles without doing difficult maths.

So there you are - study physics! Thanks for reading, and watch out for updates.
