Nobel Prize in Physics 2023

https://www.nytimes.com/2023/10/03/science/nobel-prize-physics.html.

A Nobel Prize was just awarded for the physics of attoseconds. This interests me because it represents an oft unmentioned frontier.

Let me back up a bit. It is natural to think of two opposed frontiers in physics -- the very very big and the very very small. Physicists of one sort, cosmologists, talk about the universe as a whole, how quickly it is expanding, whether there is a possibility the expansion will halt at some point and be followed by retraction, how much "dark matter" it may all contain, and so forth. The very big big picture.

Physicists of another sort, particle physicists, talk about the very small, the fundamental particles. The ones we all learned about in elementary school as well a the more exotic creatures like muons.

THOSE are the frontiers of knowledge.

But, and here we arrive at the point, the attosecond work looks at a third frontier, that of really really fast events. An attosecond is one quintillionth of a second. A decimal point followed by 17 zeroes and a 1.

Three new Nobel Physics Laureates have won the prize for their work on lasers that produce ultrashort bursts of light, Attosecond bursts. Mind blown.

This work may have practical consequences. Some of the media coverage of this particular award has focused on that. Personally, though as a pragmatist I empathize with that impulse, my mind links attoseconds to a philosophical Big Picture: Whitehead's process philosophy. Whitehead said that we should not regard the world as a bunch of things which are involved in processes, but as processes that our minds concretize as things. Entities are "complexes of occasions of experience," and experience is of process.

The very very fast would be one pole of a process-based physics. The very, very slow would be the other.

But enough of my stream of consciousness! Congratulations to the new Physics Nobel Laureates, Pierre Agostini, Ferenc Krausz, and Anne L'Huillier.

That is Dr. L'Huillier, of Lund University in Sweden, pictured above.

Dr. L'Huillier, by the way, was born in 1958. (So I share something with her.)

A Story About Coleridge

This is a quote from a memoir by Dorothy Wordsworth, reflecting on a trip she took with two famous poets, her brother, William Wordsworth, and their similarly gifted companion, Samuel Taylor Coleridge. We sat upon a bench, placed for the sake of one of these views, whence we looked down upon the waterfall, and over the open country ... A lady and gentleman, more expeditious tourists than ourselves, came to the spot; they left us at the seat, and we found them again at another station above the Falls. Coleridge, who is always good-natured enough to enter into conversation with anybody whom he meets in his way, began to talk with the gentleman, who observed that it was a majestic waterfall. Coleridge was delighted with the accuracy of the epithet, particularly as he had been settling in his own mind the precise meaning of the words grand, majestic, sublime, etc., and had discussed the subject with William at some length the day before. “Yes, sir,” says Coleridge, “it is a maj...

The Lyrics of "Live Like You Were Dying"

Back in 2004 Tim McGraw recorded the song "Live Like You were Dying." As a way of marking the one-decade anniversary of this song, I'd like to admit that a couple of the lines have confused me for years. I could use your help understanding them. In the first couple of verses, the song seems easy to follow. Two men are talking, and one tells the other about his diagnosis. The doctors have (recently? or a long time ago and mistakenly? that isn't clear) given him the news that he would die soon. "I spent most of the next days/Looking at the X-rays." Then we get a couple of lines about a man crossing items off of his bucket list. "I went sky diving, I went rocky mountain climbing, I went two point seven seconds on a bull named Fu Man Chu." Then the speaker -- presumably still the old man -- shifts to the more characterological consequences of the news. As he was doing those things, he found he was loving deeper and speaking sweeter, and givin...

Five Lessons from the Allegory of the Cave

Please correct me if there are others. But it seems to be there are five lessons the reader is meant to draw from the story about the cave. First, Plato is working to devalue what we would call empiricism. He is saying that keeping track of the shadows on the cave wall, trying to make sense of what you see there, will NOT get you to wisdom. Second, Plato is contending that reality comes in levels. The shadows on the wall are illusions. The solid objects being passed around behind my back are more real than their shadows are. BUT … the world outside the the cave is more real than that — and the sun by which that world is illuminated is the top of the hierarchy. So there isn’t a binary choice of real/unreal. There are levels. Third, he equates realness with knowability. I only have opinions about the shadows. Could I turn around, I could have at least the glimmerings of knowledge. Could I get outside the cave, I would really Know. Fourth, the parable a...
