Radiation Processes in Astronomy - Radiative Processes in Astronomy: L14b - Einsteins atomic coefficients via his original paper

In this lecture we go through Einstein's original paper where he (correctly) suggests the process of stimulated emission. This then also introduces his atomic transition coefficients, in great use for our daily work today. In second part of video we go through how we connect this to our radiative transfer language. Course: Radiation Processes in Astronomy Lecturer: Prof. Jon Sundqvist Programme: KU Leuven Bachelor Physics & Master Astronomy & Astrophysics #astrophysics #astronomy #education I record lectures live and place them here un-edited, in the hope that it will provide a more authentic feeling of the sort: "we're doing the actual work here and now". So like I keep telling students in the classroom: whenever you discover me doing some error let me know directly; for this channel this means make a comment on the videos. Then we can have a look at it, and thereby learn nicely from each other as we continue to develop our knowledge.
