And miles to go before I sleep...

In a brief speech at the 2006 Nobel Banquet in Stockholm last Sunday, this year's chemistry laureate, Roger D. Kornberg, spoke beautifully on the joy and labour of a life devoted to the pursuit of fundamental scientific knowledge.

Towards the end of his speech, Kornberg quoted from Stopping by Woods on a Snowy Evening by Robert Frost thus:

Even as we celebrate, and savor this moment, the work goes on. I am reminded of some lines from the American poet, Robert Frost. During the long, arduous effort of the past 20 years, I often repeated these lines to myself. I view them as a kind of metaphor for science and our ongoing commitment to it.

The woods are lovely, dark and deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.

And miles to go before I sleep, And miles to go before I sleep...For me, that refrain alone is enough to prove Frost's greatness. Such haunting beauty. I defy you to ever forget it. Frost does that to you. Speaking of haunting art, I once used that word, "haunting", to describe the effect of some piece of art, cinema or literature or music, I forget, to a friend. He seemed puzzled by this and asked: "Why would you want to be haunted?" I'm not sure what my answer was at the time, but I've just realised I should have said that haunting comes in many varieties.

Here's Frost again, at his haunting best, Fire and Ice:

Some say the world will end in fire,

Some say in ice.

From what I've tasted of desire

I hold with those who favor fire.

But if it had to perish twice,

I think I know enough of hate

To say that for destruction ice

Is also great

And would suffice.
