Communion Of Dreams


Tough call.

Interesting site/idea, though it would be a tough call to pick a book …

 

I’d be almost nervous to hear what someone might say about one of my books. But in spite of making solid progress with the writing of St Cybi’s Well, I seem to be at low ebb in terms of my self-confidence/bipolar cycle, so it might just be due to that.

Revisiting a very old friend.

My profession of being a book conservator is fairly unusual, and since I write about it and post images occasionally, I tend to get questions about it fairly often. The other day I got a nice query from graduate student Aaron Hain at the University of North Texas about a research assignment which included this:

The assignment is to include “a general discussion of major theories and practices and the controversies” in relation to dealing with different historic bindings. As the paper is only about 4-5 pages long, it’s obviously only able to be either very general or to cover only a couple of binding types. Could you give maybe a brief coverage of how you would deal with the conservation/preservation of a couple of different binding types and possible issues that you can run into when dealing with those bindings? In particular, the 1518 Ovid in limp vellum on your projects page caught my attention and was the one that got me to e-mail you.

 

Since it’s been 5+ years since I last posted about that, I thought I would share my brief response here.

* * *

Current practice in book conservation is to respect both the original structure as well as the history of what the book has had done to it over time. Basically, that means that I seldom try to remove all traces of damage, or rebinding, or repairs, or notes from a book and try to turn it into some pristine example of what it was when first made. Usually I try to accommodate those changes, to preserve the character of the book insofar as possible. They are, after all, part of the book’s provenance, and can teach us a great deal.

But sometimes it is necessary and appropriate to remove previous bindings/repairs, if they themselves extensively damage or threaten the continued existence of the original book. When I encounter such a book I will confer with the client and discuss options. One such case about five years ago was a copy of Ovid’s Metamorphoses printed in Venice and dated 1518. I have documented the work performed here: 1518 copy of Ovid

As you can see, we decided to put the book into a limp vellum structure, which was fairly typical for a simple and relatively inexpensive binding at that time.

Why this choice? The 19th century binding the book had been in was completely breaking down. The sewing structure was failing. The leather was deteriorated. There was nothing particularly noteworthy to the style or type of binding, and the materials it was made of would continue to cause damage to the text block. So the client elected to remove that binding, though I believe that they have kept it (separately) as part of the book’s history.

But since we had no records of what the book would have looked like its binding originally, we decided to go with a very simple and neutral structure. A blank slate, as it were, so as not to suggest a false history to future readers/custodians/conservators. While the style and material of the limp vellum binding are fairly timeless in themselves, the archival endpapers I added would clearly date the era when that binding had been created, without imposing an early-21st century aesthetic on the book. And if need be, all or part of the structure and materials could be easily removed in the future.

Just thought I’d share that. And I do love how that binding turned out.

 

If you haven’t yet, be sure to take a few minutes to enjoy the full set of pictures and text about the project.

“This book is a comfort. This book is a public service.”

That’s how a new review of Her Final Year opens. Here’s another bit:

The caregiver puts up with that out of love and decency. This book describes these things in the form of daily and weekly accounts as well as diary log pages of personal fear and depression and exasperation and recurring bubbling senses of humor. I loved this because it made me cry and it made me laugh. It’s not all drudgery. It’s hysterically funny at times. But it wouldn’t be funny at all if you didn’t love the patient. This is a book of love…

 

So often people see the words “Alzheimer’s” or “dementia” or even “care-giving” and just move on, thinking that the book (and the experience) is nothing but darkness and depression. And yeah, there is darkness there, but to borrow a phrase from Communion of Dreams/Heidegger:  “That which emerges from darkness gives definition to the light.”

We’re coming up on the three-year publishing anniversary (July 15). If you haven’t yet read Her Final Year go ahead and do so. If you want to wait a month, the Kindle edition will be available for free download around the anniversary.

And if you have read it, please consider posting your own review on Amazon or elsewhere. It helps.

Thank you.

A state of matter, or a state of mind?

From page six of Communion of Dreams:

His expert was one of best, one of only a few hundred based on the new semifluid CPU technology that surpassed the best thin-film computers made by the Israelis. But it was a quirky technology, just a few years old, subject to problems that conventional computers didn’t have, and still not entirely understood. Even less settled was whether the experts based on this technology could finally be considered to be true AI. The superconducting gel that was the basis of the semifluid CPU was more alive than not, and the computer was largely self-determining once the projected energy matrix surrounding the gel was initiated by another computer. Building on the initial subsistence program, the computer would learn how to refine and control the matrix to improve its own ‘thinking’. The thin-film computers had long since passed the Turing test, and these semifluid systems seemed to be almost human. But did that constitute sentience? Jon considered it to be a moot point, of interest only to philosophers and ethicists.

 

And, perhaps, physicists:

And while the problem of consciousness is far from being solved, it is finally being formulated mathematically as a set of problems that researchers can understand, explore and discuss.

Today, Max Tegmark, a theoretical physicist at the Massachusetts Institute of Technology in Cambridge, sets out the fundamental problems that this new way of thinking raises. He shows how these problems can be formulated in terms of quantum mechanics and information theory. And he explains how thinking about consciousness in this way leads to precise questions about the nature of reality that the scientific process of experiment might help to tease apart.

Tegmark’s approach is to think of consciousness as a state of matter, like a solid, a liquid or a gas. “I conjecture that consciousness can be understood as yet another state of matter. Just as there are many types of liquids, there are many types of consciousness,” he says.

 

Good article. Read the whole thing.

Via MetaFilter.



It’s a test.

Today’s xkcd triggered a thought: that we can think of the challenges of climate change as being akin to a planetary gom jabbar. Do we have the ability to endure short-term pain and survive, or do we give in to our immediate short-term desires and suffer the consequences?

By the book.

From Chapter 7 of St. Cybi’s Well:

Long training had taught him to put his trust in facts. In objective, testable reality. You didn’t fly a space shuttle – even one which had been stripped down to the bare essentials for transporting sealed sleeper modules – by the seat of your pants. That would very quickly get you killed. You flew it by the book, with close attention to your instrumentation and computer systems. Because your instincts would lie to you. Your hopes and dreams had no place in orbital calculations. The only miracles which existed were the ones created by careful science, proven engineering, and rigorous quality control.

 

And from a great entry today on Bad Astronomy:

The European Space Agency has put together a fantastic and enthralling video that goes through the steps taken to bring the space travelers down. This is seriously worth 20 minutes of your time.

 

Yeah, it is really cool to watch them go through it all by the book. Find the time to watch it.

Call it a ‘practice run.’

Been a while since I posted an excerpt. Partly that has been due to the fact that a number of  different things have conspired to slow down my writing progress the last few weeks. But I finally seem to be making good headway again, and thought I would share a bit from today’s efforts:

Darnell nodded. “Sure. Now let’s take a look at that satellite map.”

He pulled out his phone again, tapped it a couple of times. Soon they were looking down at their current location centered on the map, with the resolution such that Pentre Ifan was off on the very left edge of the screen. St. John pointed at a slightly lopsided ring due north of Craig Rhosyfelin about the same distance from Pentre Ifan. “There. See?”

Darnell zoomed in on the image. The ring expanded until it was about half the size of the screen. It was actually a double ring of trees, bisected by a chevron of a single line of trees. “Yeah, OK. Not a perfect circle. Looks like it has a bit of a pinch on the east side, almost as if pointing that way.”

“Exactly!”

“I’m sorry, I don’t follow you.”

St. John pointed at the screen. “Points due east. That’s because before it was made into a hill fort, there’s evidence to suggest that it was a henge.”

“Huh.” Darnell looked at the image again. “Yeah, I can see that.”

“And I think that it wasn’t just any henge. I think that it was the precursor to Stonehenge.” St. John looked at Darnell, and there was a slightly mad gleam in his eye. “In fact, I think that the henge which was there was disassembled and then transported to Wiltshire and rebuilt as the structure we all know today.”

 

The site they’re discussing is Castell Mawr.

Obviously.

If you consider the full implications of what is revealed in Communion of Dreams, this might well be a fairly good explanation …

From the brilliant Randall Munroe, of course. Go to his site to see the ‘hidden text’.

Of course they do.

From Chapter 1 of Communion of Dreams:

“I’ve had my expert do a preliminary search through the old NASA archives. I recalled that they had protocols for dealing with such possible situations, and I doubt that anyone else has really thought much about it since the turn of the century.

“In addition to Don’s field team, the preliminary search suggests that another component should be theoretical, a mix of disciplines so that we can get as broad a spectrum of experience and mind-set as possible. Probably we should have an expert in computer technology. A cultural anthropologist. Someone with a background in game theory and communication strategy. An artist or two. We’ll see if a more thorough survey of the NASA material has any good suggestions beyond that. I’ll get to work identifying appropriate individuals.”

 

Well, guess what news was announced last week:

During the past few years, NASA has released a series of free ebooks, including NASA Earth As Art and various interactive texts focusing on the Webb and Hubble space telescopes. Last week, they added a new, curious book to the collection, Archaeology, Anthropology, and Interstellar Communication. Edited by Douglas A. Vakoch (the Director of Interstellar Message Composition at the SETI Institute), the text contemplates how we’ll go about “establishing meaningful communication with an extraterrestrial intelligence.” The scholars contributing to the volume “grappl[e] with some of the enormous challenges that will face humanity if an information-rich signal emanating from another world is detected.” And to make sure that we’re “prepared for contact with an extraterrestrial civilization, should that day ever come,” they draw on “issues at the core of contemporary archaeology and anthropology.” Why archaeology and anthropology? Because, says Vackoch, communication with intelligent life probably won’t be through sound, but through images. We will need to read/understand the civilization we encounter based on what we observe.

 

Heh. I love seeing this stuff happen.

This is a big deal.

Short paragraph. Big implications:

Abstract

Realizing robust quantum information transfer between long-lived qubit registers is a key challenge for quantum information science and technology. Here, we demonstrate unconditional teleportation of arbitrary quantum states between diamond spin qubits separated by 3 m. We prepare the teleporter through photon-mediated heralded entanglement between two distant electron spins and subsequently encode the source qubit in a single nuclear spin. By realizing a fully deterministic Bell-state measurement combined with real-time feed-forward quantum teleportation is achieved upon each attempt with an average state fidelity exceeding the classical limit. These results establish diamond spin qubits as a prime candidate for the realization of quantum networks for quantum communication and network-based quantum computing.

 

Decent explanation (at least from what I know) in this article. Excerpt:

Scientists in the Netherlands have moved a step closer to overriding one of Albert Einstein’s most famous objections to the implications of quantum mechanics, which he described as “spooky action at a distance.”

In a paper published on Thursday in the journal Science, physicists at the Kavli Institute of Nanoscience at the Delft University of Technology reported that they were able to reliably teleport information between two quantum bits separated by three meters, or about 10 feet.

 

Ten feet may not sound like much, but it is a huge increase — previously, reliable teleportation of information was on the scale of just billionths of a meter. This change opens the door to functional quantum computing, which would have the same relation to current computing power that current computing power has to mechanical calculating machines of about the WWII era.
