My encounter with RNA

My Encounter with Quantum Computing An Introduction to Quantum Computing

Reminiscences on my life with RNA: a self-indulgent perspective.

In 1970 I came to MIT as a postdoc with Sheldon Penman. After my PhD in Developmental Biology studying chicken limb development, I was unsatisfied with phenomenology and decided that I wanted to get to the mechanics of cell differentiation. I chose the new field of molecular biology. I knew nothing about RNA, but thought it sounded like the molecule to work on if one was to pursue cell differen...

An Encounter with Graphs

So far diagnosis of some problems we came across during our works with algorithms, graphs played significant roles. In this paper, we have tried to show that graphs really occupy a major role in computer science and engineering. The abstraction of problems as different graph models as well as graphs in digital system design methodology allows us to have a close look or refresher outlook on grap...

A Brief Philosophical Encounter with Science and Medicine

We show a lot of respect for science today. To back up our claims, we tend to appeal to scientific methods. It seems that we all agree that these methods are effective for gaining the truth. We can ask why science has its special status as a supplier of knowledge about our external world and our bodies. Of course, one should not always trust what scientists say. Nonetheless, epistemological jus...

The origin of RNA and "my grandfather's axe".

The origin of RNA is one of the most formidable problems facing prebiotic chemists. We consider RNA as a product of evolution, as opposed to the more conventional view of RNA as originally being the product of abiotic processes. We have come to accept that life's informational polymers have changed in chemical structure since their emergence, which presents a quandary similar to the paradox of ...
