The scale of things
As the Greek philosopher Protagoras would say 'man is the measure of all things'. We look at the world through our own eyes and tend to think that the human scale is the standard size of measurement. Of course it's a guideline for our everyday life, but if we take a closer look, what is it that make up a coffee cup, a book, a landscape or an other person? We have some equipment at our disposal to answer this question.
