The number of requests I receive has grown to an amount I cannot scope with any longer. So, please do not send me general questions, even if they have something to do with my fields of interest. I simply do not have the time to reply, even if I know the answer. (See also: Requests concerning history of astronomy.)
However, I will reply to your messages in case that you have a professional interest similar to mine and would like to discuss some special points, or if you have some material on these subjects. In this case, please write to email@example.com.
Thanks for your understanding.
