For release in July, the book "Physical foundations of spectroscopy" by Philip Judge offers an introduction and reference to the subject of spectroscopy. Aimed towards fresh graduates and seasoned teachers and researchers alike, Judge guides readers through subjects of a physics undergraduate degree, from classical and quantum mechanics to spectroscopy. The approach is to highlight, through chapters familiar in undergraduate physics, how spectroscopy is firmly anchored in physical foundations, countering modern trends leading to over-specialization. The text culminates in the theory of transport processes in laboratory and space plasmas, and atmospheres, using the solar spectrum as a touchstone. Problem sets are included, making this unusual book suitable for advanced undergraduate or graduate classes. The book is published by Oxford University Press as a text in their master series in particle physics, astrophysics and cosmology.
