That which is not measurable is not science. That which is not physics is stamp collecting.

- Ernest Lord Rutherford

Physics is the foundation of all things.

It is the scientific study of the natural world: humanity's endeavour to understand the universe and everything within it. Physics forms the fundamental basis for all the other scientific disciplines, both theoretical and applied: chemistry, biology, medicine, psychology, engineering, among many others - and one day, we will be able to understand and derive all these "secondary" phenomena from fundamental physical principles alone (we're not quite there yet).

So this is why I have titled this category "Physics", even though much of the content might be more conventionally classed under engineering, mechanics or "tech": it is to reflect my firmly held belief that at the heart of all these problems are the fundamental physical laws that govern the natural world - nothing more, nothing less.

It also serves as a reminder for me in all these writings to be unrelenting in the critical application of the scientific method. The test of all knowledge is experiment. It is not always possible for me to perform experiments personally. When I cannot, I will as much as possible reference peer-reviewed literature from respected journals whose methodology I have checked myself. It is all too often in "popular science" that good science is butchered by sloppy second hand presentation, and I will do my best to avoid this pitfall.

To that end, I would like also to ask you, the reader, to be ruthlessly critical towards what I write here and protest whenever I fail to uphold the standards that I have set out.
