Communion Of Dreams


Out for a stroll.

I mean, who doesn’t want to get out now and again, stretch your legs a bit?

More info here:

Recently, NASA released some pretty spectacular footage captured by an astronaut wearing a GoPro camera while spacewalking around the International Space Station. In the videos, Earth slowly rotates below the space station while astronauts fiddle with cables, install antennae, and work on the robotic arm.

That’s just cool.

Via BoingBoing, fun video from NASA of the unboxing of a shipment of the first printed tools and tests parts from the ISS:

Perhaps it’s just the conservator in me, but I loved the documentation process, and how they’re going through everything carefully. No doubt that some or all of those items will eventually wind up at the Smithsonian Air & Space Museum.

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.

Watch this.

Yeah, what Phil said:

Stop whatever you’re doing (unless you’re performing brain surgery) and watch this astonishing and enthralling time-lapse video, showing the Earth from space using photographs taken by astronauts aboard the International Space Station

Ahh …

Oh, there’s a new review up for Communion of Dreams. Here ’tis:

I rarely read sci-fi anymore, but this reminds me of the best I read when I was younger. There’s a lot of background on the worlds the author is creating, followed by a resolution to multiple problems in the worlds. I truly enjoyed it.

If you’ve read the book and haven’t yet gotten around to posting a review, please consider it. It’s a little thing that does more than just massage my ego — it helps others have some idea what to expect from the book. And every so often I do things like give away nice hand-bound copies of the book . Thanks.

Yes, this *is* the future.

How cool is this?

How cool is Chris Hadfield?

A matter of perspective.

It all depends on your point-of-view:

More words.

Following up from Sunday

“Stupidity cannot be cured with money, or through education, or by legislation. Stupidity is not a sin, the victim can’t help being stupid. But stupidity is the only universal capital crime: the sentence is death, there is no appeal, and execution is carried out automatically and without pity.”
Robert A. Heinlein, Time Enough For Love

There was a very interesting discussion on the Diane Rehm show the other day with Stuart Firestein, who is the chairman of the Department of Biology at Columbia University as well as a professor of neuroscience. The whole thing is worth a listen, but in particular there were a couple of particular bits I wanted to share. Here’s the first:

So in your brain cells, one of the ways your brain cells communicate with each other is using a kind of electricity, bioelectricity or voltages. And we’re very good at recording electrical signals. I mean, your brain is also a chemical. Like the rest of your body it’s a kind of chemical plant. But part of the chemistry produces electrical responses.

And because our technology is very good at recording electrical responses we’ve spent the last 70 or 80 years looking at the electrical side of the brain and we’ve learned a lot but it steered us in very distinct directions, much — and we wound up ignoring much of the biochemical side of the brain as a result of it. And as it now turns out, seems to be a huge mistake in some of our ideas about learning and memory and how it works.

* * * * * * *

I stared at the body, blinking in disbelief. We were in the shadow of the First Step, so the light was dull. The body lay about 10 metres from where I stood and was angled away from me. It jerked – a horrible movement, like a puppet being pulled savagely by its strings.

We had been on a well-organised and, so far, successful trail towards the summit of Everest, worrying only about ourselves. Now a stranger lay across our path, moaning. Lhakpa shouted down at me and waved me to move on, to follow him up onto the Step. I looked back at the raggedly jerking figure.

From here.

From about halfway through Chapter 6 in Communion of Dreams:

“But smart how?”

Jon looked at him. “What do you mean?”

“Well, there are lots of kinds of intelligence, and I’m not just talking about the reasoning/emotional/spatial/mechanical sorts of distinctions that we sometimes make. More fundamentally, how are they smart? Are they super-geniuses, able to easily figure out problems that stump us? Or maybe they’re very slow, but have been at this a very long time. Perhaps some sort of collective or racial intelligence, while each individual member of their species can barely put two and two together. There are a lot of different ways they can be intelligent.”

* * * * * * *

(Warning – the page from which the following comes contains gruesome images and text.)

Above a certain altitude, no human can ever acclimatize. Known as the Death Zone, only on 14 mountains worldwide can one step beyond the 8000 meter mark and know that no amount of training or conditioning will ever allow you to spend more than 48 hours there. The oxygen level in the Death Zone is only one third of the sea level value, which in simple terms means the body will use up its store of oxygen faster than breathing can replenish it.

In such conditions, odd things happen to human physical and mental states. A National Geographic climber originally on Everest to document Brian Blessed’s (ultimately botched) attempt at summiting, described the unsettling hallucinogenic effects of running out of oxygen in the Death Zone. The insides of his tent seemed to rise above him, taking on cathedral-like dimensions, robbing him of all strength, clouding his judgement. Any stay in the Death Zone without supplementary oxygen is like being slowly choked, all the while having to perform one of the hardest physical feats imaginable.

It makes you stupid.

* * * * * * *

Again, Stuart Firestein:

And in neuroscience, I can give you an example in the mid-1800s, phrenology. This idea that the bumps on your head, everybody has slightly different bumps on their head due to the shape of their skull. And you could tell something about a person’s personality by the bumps on their head. Now, we joke about it now. You can buy these phrenology busts in stores that show you where love is and where compassion is and where violence is and all that. It’s absolutely silly, but for 50 years it existed as a real science. And there are papers from learned scientists on it in the literature.

Update at 12:10 p.m. ET. Dragon Has Docked:

Dragon has finished docking with the International Space Station. That makes SpaceX the first private company to dock a cargo spacecraft to the space station.

That happened at exactly 12:02 p.m. ET, according to NASA.

Last weekend four more people died attempting to summit Everest. Partly, this seems to have been due to the traffic on the mountain. Yeah, so many people are now attempting to climb the mountain that there are bottlenecks which occur, which can throw off calculations about how long a climb will take, how much supplemental oxygen is necessary, and whether weather will move in before climbers can reach safety.

In theory, everyone who attempts such a climb should know the odds. One in ten people who attempted the summit have died.

But we live in an age of accepted wonders. We think we’re smart enough to beat the odds.
