This book is about language in STEM research and about how it is thought about: as something that somehow refers to something else not directly accessible, often meaning, mental representation, or conception. Using the analyses of real data and analyses of the way certain concepts are used in the scientifi c literature, such as "meaning," this book reframes the discussion about meaning, mental representation, and conceptions consistent with the pragmatic approaches that we have become familiar with through the works of K. Marx, L. S. Vygotsky, M. M. Bakhtin, V. N. Vološinov, L. Wittgenstein, F. Mikhailov, R. Rorty, and J. Derrida, to name but a few.
