Assuming anyone is still checking in here - I wonder what keeps people from posting. Here's what has kept me from posting:
After I exercised some stock options in the client company that I've done work for the last 10 years and become part owner, I've found an extra incentive to make sure things go well there. We have had a major development project underway for the last year that has sucked my time. So work has kept me busy.
The closest I've come to nanotechnology lately is that I started studying the Kindle edition of Molecular Biology of the Cell, 6th edition, by Alberts et al (MBoC) from beginning to end. I've had a copy of the third edition for about 15 years but had only ever used it as a reference; never tried to read it all the way through. As I started reading the 6th edition (to fill in gaps in my knowledge and get more up to date info) I became curious about the history of molecular biology, so I went looking for recommendations on books on the subject. Based on reviews, I bought a copy of Operators and Promoters: The Story of Molecular Biology and Its Creators, by Echols and Gross. Early on it said if I wanted to know more about the period it didn't cover, I should read The Double Helix by Watson and The Eighth Day of Creation: Makers of the Revolution in Biology, by Judson. (There is a commemorative edition of the latter that I only discovered later.)
So I read Double Helix, then The Eighth Day, and am just now finishing Operators and Promoters. Once done I'll get back to finishing MBoC. Except I can't help it, I got curious about the history of chemistry, so a copy of The Development of Modern Chemistry by Ihde will be arriving soon.
Lastly, not sure why it took me so long, but bought a 3D printer and downloaded a free copy of DesignSpark Mechanical so I could design the types of things I wanted to print. Fun stuff - if I had more time I'd be designing and building some nanotech related tools. It's amazing sometimes how much time one expends on the allegedly "trivial" aspect of mounting and arranging parts in some apparatus. Sure, it may take hours to print the needed parts, but it can take that long or even longer to do the same using the tools in a garage workshop.
