You are invited to participate in a new forum established to share ideas and information related to lost art in the mathematical sciences. If you have feedback related to a specific essay or its user comments, please continue to provide comments at the end of the post. Otherwise, for general comments or suggestions for future essays, and in fact for wide-ranging discussions on erstwhile discoveries in mathematics and science, please feel free to post entries on the forum here, specifically on the discussion board for this blog. I will be posting essays here as I always have, and I’m still soliciting guest essays for this blog—the forum is simply a separate but related enterprise that involves more people and opens up more topics.
