Editorial – Is there a by-product of fundamental physics?

What is the aim of fundamental science? We have all asked ourselves this question, and however naive it may seem, we often have to provide an answer. When the question comes from policy makers and funding agencies, we suspect ulterior motives. Therefore, rather than explain that the purpose is to gain knowledge and understanding, which is the essence of fundamental science, it is easier to raise an equally important aspect: most of the greatest technological advances are the direct or indirect consequence of not politically oriented research. One example that is often mentioned is the invention of the laser.
