Thanks D'moy! I'm still having fun with Klein bottles and other topological manifolds. Toying with immersions of the projective plane and several knot embeddings.

At the moment, retirement mainly means "start taking out required minimum distributions".

All the same, I wonder: How do you retire from a marginally profitable nano-business built upon glass mathematical shapes? How'd I ever reach 74 years old?

The Acme Klein bottle and its packaging materials are among my prize possessions.

And 'The Cuckoo's Egg' was a great read.

Thank you for being you.

Aside from those I also loved the photos I got with the bottle and him in his garden. Thanks Cliff (:

Find someone interested in continuing that business under a long term (royalty or such) or short term (lump sum) financial arrangement that is acceptable to you? I think there will be interested people, maybe even within this community (not suggesting I’m one of them, though).

Or he could go full Japanese and adopt the business heir into his family.

... actually, that might be safer so as to not raise any red flags with Citibank. /s

There are lots of us that made good money over the years and your books were important to lots of us.

Sell signed copies of your books for $1000 at the klein bottle store so we can buy them. Let us help you have fun in your retirement! (A signature or signed bottle would be awesome too.)
