What is Life? A 21st Century Perspective
J. Craig Venter on the 70th Anniversary of Schroedinger's Lecture at Trinity College, over at Edge:
As you all know, Schrödinger's book was published in 1944 and it was based on a series of three lectures here, starting in February of 1943. And he had to repeat the lectures, I read, on the following Monday because the room on the other side of campus was too small, and I understand people were turned away tonight, but we're grateful for Internet streaming, so I don't have to do this twice.
Also, due clearly to his historical role, and it's interesting to be sharing this event with Jim Watson, who I've known and had multiple interactions with over the last 25 years, including most recently sharing the Double Helix Prize for Human Genome Sequencing with him from Cold Spring Harbor Laboratory a few years ago.
Schrödinger started his lecture with a key question and an interesting insight on it. The question was "How can the events in space and time, which take place within the boundaries of a living organism be accounted for by physics and chemistry?" It's a pretty straightforward, simple question. Then he answered what he could at the time, "The obvious inability of present-day physics and chemistry to account for such events is no reason at all for doubting that they will be accounted for by those sciences." While I only have around 40 minutes, not three lectures, I hope to convince you that there has been substantial progress in the last nearly 70 years since Schrödinger initially asked that question, to the point where the answer is at least nearly at hand, if not in hand.
I view that we're now in what I'm calling "The Digital Age of Biology". My teams work on synthesizing genomes based on digital code in the computer, and four bottles of chemicals illustrates the ultimate link between the computer code and the digital code.
Life is code, as you heard in the introduction, was very clearly articulated by Schrodinger as code script. Perhaps even more importantly, and something I missed on the first few readings of his book earlier in my career, was as far as I could tell, it's the first mention that this code could be as simple as a binary code.
