People often think of different fields as very distinct from each other, partly as a result of the way we learn different subjects in school. Physics is different from chemistry, which is different from biology. Of course that's how it is! We often lose sight of, or never even learn in the first place, how these fields come together and intersect and overlap. If we had a better understanding of how different fields could enhance and affect each other, we would be much better at thinking outside the box and coming up with all sorts of creative solutions to various societal challenges. For instance, most people (myself included) might not have thought that solar cells (also called " photovoltaics ") could be useful for biomedical research applications beyond powering the tools and equipment needed for such research. However, there is a thriving subset of such research that uses photovoltaics and related structures to actually understand cells better. This is possible in pa...
