Universities and Scientific Inquiry
In this segment, Leonardis explores the role of universities in supporting scientific inquiry. He argues that while institutions are valuable for fostering collaboration and knowledge sharing, the traditional understanding of science may not fully capture the diverse activities taking place within these academic settings.
