Don’t be shy, if you admit it, I would fully understand you The history of science is full of such examples, which have usually brought about far reaching revolutions, with effects that have gone well beyond the strict academic circles and, in the end, have influenced philosophy and the way we perceive the world. Just think about Copernicus… Many of us (including myself) spend their scientific careers working on subjects which are usually dubbed “small science”.
