- Once upon a time I attended a lecture where something remotely
- relevant to "soup computation" was said. I took note of it.
- Now I am unable to find that piece of paper and even to
- remember who gave that lecture (It might have been Sherrington).
- In the hope that someone can bring in more precision and
- reliability, here is what I think I remember (no garantee given!):
- <<
- In a cell each enzyme synthesis is under the control of 1 or 2
- enzymes.
- In turn, each enzyme controls the fabrication of 1 or 2 other
- enzymes.
- This can be thougth of as a DILUTE NEURAL NETWORK.
- There are ~ 10000 enzymes.
- Dilute neural network theory states that the length of a cycle
- is around the square root of the number of neurons (enzymes here).
- Complete cell division takes ~10 minutes, 600 secs, which is
- roughly Sqrt(10000.)=100. times the time for elementary enzyme
- synthesis ~6 secs.
- >>
- If someone has the exact reference, or can improve/correct/deny
- the argument please post in this group.
- I hope that this partly answers the original question.
