DNA computing

I have thought long about biological computing. DNA computing seems too slow for the Terra-Flop crowd, but this one describes DNA which uses computing sections to treat diseases in an algorithmic way. Very cool!

What I would like to see is a molecular level monostable vibrator circuit (flip-flop) which could be the basis for a molar computer.

I would think that a small molecule in a crystal array with 1) two stable states, 2) a way to fip the states and 3) a quick way to query the states would be a very fast way to store data a million times more dense than any magnetic or solid state array.

I would guess that it would be like the old magnetic core. A two signals could be used to query a 2D location. The signals themselves would generate a change in state all along the path, where two signals met the state would not change and a slightly higher impedance would be measurable. The system would have to reset itself back to original state by sending the two signals separately and the target spot would be in an inverse state. (This is way too hard to explain without diagrams.)

Anyway, I am waiting to see if someone is actually doing this.

The only drawback is that the system will generate heat so that whatever molecule is used will have to be resistant to going fut when the current goes up.

 

Buy the Book!

I cleaned up my tab for Sonny Boy's Help Me and made it into a short book. There's a Kindle version for 99 cents, and if you buy the paperback you get the Kindle free.

Playing "Help-Me" In the Style of Sonny Boy Williamson II: A step by step, note for note analysis of some of Sonny Boy's Signature Riffs

I also write Science Fiction, so you can sample some of my best stories. Also available in Kindle format.

I started reading Science Fiction in the 1950s. I started Writing SF in the 1960s. Then, I had a life. Now I am retired, raising chickens and keeping bees. I am still an avid reader and I have sold about 70 stories in the last 20 years.
I have been collecting information about writing Science Fiction for many years now. Social media has replaced the Blog and large dedicated websites, so the pages here are mostly static. I update them from time to time.

Enjoy!
