Originally posted by Bad wolfA master class is often about music or theater at the performance level, but obviously not in this case. It will include a lecture or demonstration by a visiting expert or someone on the cutting edge. It could be interactive and should be stimulating -- if you're a student of astrophysics, or even a fan of astronomy. Have fun.
Tomorrow I'm getting a brief lecture, 'master class', to see a presentation about astronomy, the topic being dark matter.
Um, what is a master class anyway? 😕
