This issue of iWonder... is centered on evolution, a concept that today is almost synonymous with Charles Darwin. However, in a strange but fitting way, the word evolution, derived from the Latin ‘evolvere’, was originally used to refer to the ‘unrolling of a book’. And it was, in fact, Charles Lyell who first used this term with its modern meaning – twenty-seven years before Darwin used it once in the final paragraph of his ‘On the Origin of Species’. Thus, it is Lyell’s notion that ‘the present is the key to the past’, a key first principle in almost every field of science, which is the underlying thread linking the articles in this issue – from the evolution of stars and the Earth to that of living organisms, humans, or even the phenomenon of ocean acidification.
The beauty of science is that there is no absolute truth. As newer technologies develop and newer discoveries are made, newer mysteries emerge, requiring more collaborative work and even more advanced technologies to solve them. Thus, science is a never-ending quest to understand the nature of the universe and how best humanity can tap its unlimited resources. We hope that this issue of ‘ i wonder...’ ignites the spark to embark on that quest in each of our readers.
In our inaugural issue, we explore an important aspect of science that is seldom evident in school textbooks - its inter-disciplinarity. To understand any concept in its entirety, we must examine it from the perspective of many streams- physics, chemistry, biology and others and often through combining these disciplines. Hence, the theme for this issue is interdisciplinary science.
