Communion Of Dreams


How so very … random.

There’s “random“, and then there’s random.

Huh.

MINNEAPOLIS / ST. PAUL (09/03/2013) —An international group of researchers from the University of Minnesota, Argonne National Laboratory and Seoul National University have discovered a groundbreaking technique in manufacturing nanostructures that has the potential to make electrical and optical devices smaller and better than ever before. A surprising low-tech tool of Scotch Magic tape ended up being one of the keys to the discovery.

The research is published today in Nature Communications, an international online research journal.

Combining several standard nanofabrication techniques—with the final addition of the Scotch Magic tape—researchers at the University of Minnesota created extremely thin gaps through a layer of metal and patterned these tiny gaps over the entire surface of a four-inch silicon wafer. The smallest gaps were only one nanometer wide, much smaller than most researchers have been able to achieve. In addition, the widths of the gaps could be controlled on the atomic level. This work provides the basis for producing new and better nanostructures that are at the core of advanced electronic and optical devices.

And no, it’s not graphene.

In a small side discussion on the larger topic of space exploration, this comment was made in response to the characterization of those who have said that they would be willing to take a one-way trip to Mars were ‘nuts’:

It’s disturbing that people would choose death on Mars over life eternal here in the undying lands of Earth.

Yeah, pretty much my take on things, as well.

This is over-simplified, but good nonetheless:

There’s “random“, and then there’s random. And yes, that is very much how Margo Lynn goes through life, from what I’ve seen in knowing her the last couple of decades. But it works, and keeps things interesting.

So, congrats to TanteLiz and to CJ, who will receive the leather-bound and ‘nearly perfect‘ copies of Communion of Dreams, respectively. Thanks to all who participated.

And particular thanks to Margo Lynn for adding her own somewhat random take on determining the winners, as well.

Proof of concept.

Interesting:

Imagine three astronauts, 125 million miles from the Earth, talking to Mission Control with a four-minute time lag. They have seen nothing out their windows but stars in the blackness of space for the last 150 days. With a carefully timed burn, they slow into orbit around Venus, and as they loop around the planet, they get their first look at its thick cloud layer just 7,000 miles below.

It might sound like the plot of a science fiction movie, but in the late 1960s, NASA investigated missions that would send humans to Venus and Mars using Apollo-era technology. These missions would fly in the 1970s and 1980s to capitalize on what many expected would be a surge of interest in manned spaceflight after the Apollo lunar landings. They would be daring missions, but they would also be feasible with what was on hand.

 

Somewhat surprisingly, I don’t remember this at all. Though of course these were just “proof of concept” studies which were put together for NASA.  Still, they were fairly well thought-out, as the article on ars technica demonstrates. As is often the case, technological limitations are less of an absolute factor in accomplishing something than economic/political limitations are. To borrow from a favorite old movie: “You wouldn’t believe what we did. It’s possible. It’s just hard work.”

What isn’t hard work? Getting entered into the drawing for a leather-bound copy of Communion of Dreams. Full details here. Yesterday’s Kindle promotion pushed us over 500 copies of the electronic version given away this month, and that puts the total number of copies out there somewhere in the neighborhood of 26,000. There are already 65 reviews posted to Amazon. Yet so far only 9 people have entered the drawing. You have until midnight this coming Saturday.

The end of things.

This morning, NPR repeated the story of Voyager 1 having apparently left the solar system.

I wonder why?

Philip James Bailey, Festus:

We live in deeds, not years; in thoughts, not breaths;
In feelings, not in figures on a dial.
We should count time by heart-throbs. He most lives
Who thinks most, feels the noblest, acts the best.
Life’s but a means unto an end; that end
Beginning, mean, and end to all things,—God.

We went shopping yesterday.

Big deal, right? Actually, it kinda was. It was the first time my wife had been in good enough shape to do so since her emergency appendectomy. Things are slowly returning to whatever passes for normal.

Dr. David Casarett is the director of hospice care at the Perelman School of Medicine at the University of Pennsylvania. He works with families as they try to navigate end-of-life decisions.

At least once a week, Casarett says, one of his patients expresses a desire to end his or her own life. “It’s a reminder to me that I have to stop whatever I was doing … and sit back down to try to find out what is motivating that request,” he says. “Is it really a carefully thought out desire to die, or is it, as it is unfortunately many times, a cry for help?”

It’s a good story.

Tomorrow’s the last day this month to get the free Kindle edition of Communion of Dreams. And this week is the last one to get entered into the drawing for a hand-bound leather copy of the special edition. Remember, you have to have posted a review on Amazon of the book, and then post a comment with a link to that review in this blog entry. There are currently 65 reviews on Amazon, but only 8 entrants for the drawing — don’t delay, as the end will come sooner than you expect.

As it usually does, for good or ill.

Moments of revelation.

“All of life can be broken down into moments of transition or moments of revelation.”

-G’Kar, Z’ha’dum

Sometimes you don’t recognize when things change — the moments of transition — except in hindsight. That could be because the change is incremental enough that you don’t notice it for a while, or it might be that you’re so completely involved in the moment that the realization of what just happened doesn’t sink in immediately.

This morning there was a news item on NPR which caught my attention: that perhaps the Voyager 1 spacecraft has already left our solar system.

Scientists have known for a while that it was approaching the limits of the heliosphere. The expectation was that there would be a fairly clear change in orientation of the magnetic field when the craft crossed the boundary of the Sun’s influence into true interstellar space.  But perhaps that boundary was less defined than we thought. From the story:

How did we miss that? As it turns out, it wasn’t entirely our fault. Researchers thought the solar system was surrounded by a clearly marked magnetic field bubble.

“There’s one at the Earth, there’s one at Jupiter, Saturn, many planets have them. And so just by analogy we were expecting there to be something like that for the solar system,” Swisdak says.

Scientists were waiting for Voyager to cross over the magnetic edge of our solar system and into the magnetic field of interstellar space. But in in the September issue of Astrophysical Journal Letters, Swisdak and his colleagues say the magnetic fields may blend together. And so in July 2012, when Voyager crossed from the solar system into deep space, “Voyager just kept cruising along,” Swisdak says. All they saw was a change in the field’s direction.

Last Thursday my wife had a follow-up with her surgeon to see how she was doing in recovering from her emergency appendectomy.  She had been released from the hospital the previous Saturday, but there was some concern over the risk of secondary infection within her abdomen.

Well, without getting too much into the details, tests indicated that she might be developing exactly that sort of infection. The surgeon ordered a procedure called a needle aspiration and scheduled it for the following day.

We dutifully reported to the hospital for the procedure. It didn’t go smoothly, and the upshot was that it didn’t help her condition at all. A couple hours later we left the hospital, and she’s been mostly resting since. We’re now waiting to hear from the surgeon about what happens next. And what it means.

Some six years ago I wrote what could be considered a companion piece to this blog post. In it I quoted a friend, talking about Communion of Dreams:

“Yeah, but it’s like the way that the people involved in your book – the characters – are all struggling to understand this new thing, this new artifact, this unexpected visitor. And I like the way that they don’t just figure it out instantly – the way each one of them tries to fit it into their own expectations about the world, and what it means. They struggle with it, they have to keep learning and investigating and working at it, before they finally come to an understanding.” He looked at me as we got back in the car. “Transitions.”

 

* * *

Where Communion of Dreams was largely about transitions, in many ways St. Cybi’s Well is about revelations. How we experience them. How we understand them. How we do or don’t recognize them when they happen.

The Kindle edition of Communion of Dreams is free today. And you have less than two weeks to enter into the drawing for a hand-bound, full-leather copy of the book. So far only two people have entered. Don’t miss the moment.

Because …

… I’m a big 2001: A Space Odyssey fan, as well as a paleo-future geek, I offer this wonderful insight into my past/future:

“2001: A Space Odyssey” Howard Johnsons Children’s Menu (1968)

Yeah, that’s what it was like back in ’68. Definitely.

Gorgeous:

The Rose

The spinning vortex of Saturn’s north polar storm resembles a deep red rose of giant proportions surrounded by green foliage in this false-color image from NASA’s Cassini spacecraft. Measurements have sized the eye at a staggering 1,250 miles (2,000 kilometers) across with cloud speeds as fast as 330 miles per hour (150 meters per second).

A fascinating short video and full explanation can be found on NASA’s site:

PASADENA, Calif. – NASA’s Cassini spacecraft has provided scientists the first close-up, visible-light views of a behemoth hurricane swirling around Saturn’s north pole.

In high-resolution pictures and video, scientists see the hurricane’s eye is about 1,250 miles (2,000 kilometers) wide, 20 times larger than the average hurricane eye on Earth. Thin, bright clouds at the outer edge of the hurricane are traveling 330 mph(150 meters per second). The hurricane swirls inside a large, mysterious, six-sided weather pattern known as the hexagon.

Very cool. If I ever have reason to revise Communion of Dreams, I would certainly include reference to The Rose since most everything happens on and around Titan.

Whoa.

No, really … whoa.

Goldilocks and the three exoplanets.

As something of a follow-up to yesterday’s post, news today of the discovery (thanks to the Kepler mission) of three exoplanets which are very good candidates for harboring life. First, their size is within an order of magnitude of Earth’s — and, specifically, less than twice the size of Earth — meaning that they’re not gas giants such as Saturn or Jupiter. Secondly, and at least as importantly, they fall within the “habitable zone” in their star system. That’s the so-called “Goldilocks Zone” where liquid water can exist (it’s not too cold and not too hot).

This is exciting! As it is put in the article:

Two of the three detailed in the new findings in the journal Science are of particular interest: Kepler-62-e and Kepler-62-f. William Borucki, the chief scientist for NASA’s Kepler telescope, says the planets are slightly wider than Earth, but not too big. Kepler-62-e is a bit toasty, like a Hawaiian world and Kepler-62-f is a bit nippy, more Alaskan, Borucki tells the AP.

“This is the first one where I’m thinking, ‘Huh, Kepler-62-f really might have life on it,’ ” said study co-author David Charbonneau of Harvard. “This is a very important barrier that’s been crossed. Why wouldn’t it have life?”

Why, indeed?
