Radiation Processes in Astronomy - Radiation Processes in Astronomy: L2 - Radiative Flux

This lecture introduces the radiative flux. It first emphasises its vectorial nature, then we move on to showing and discussing why in a lot of astronomical education and research we rather talk about "the flux" as if it were a scalar. 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.
