Abstract:  Nearly 3.5 billion years back microtubule came into being, while unravelling its electronics we found its synchrony induced behavior (1), which enables it to exhibit remarkable electronic properties never seen before. Our results show that synchronous behavior leads to non-linear frequency pulling which enables neutral network to solve problems much faster. Inspired by these process we devised organic monolayer, and solved two intractable problems on this surface in finite time (2). We are now building artificial molecular systems we call it nano-brain for robots that will learn & take decisions by itself without human intervention. We do not need to write program or algorithm, it is a new simple way to design molecular structure to execute around hundred "if-then" arguments simultaneously, note that simultaneity is not parallel. Thus, we combine results obtained from electronics studies of real bio-materials, devise computing principles (3) and then implement it into building artificial systems, in all our works we suggest that the new generation computing would be communicating "one-to-many at-a-time".
