Communion Of Dreams


Well, it’s not a von Neumann machine*,

nor even a simple ‘microbot‘ from Communion of Dreams, but still, this is pretty cool and could lead to either of those technologies:

Transformer Paper Turns Itself Into A Robot. Cool!

Every so often, a scientific paper just begs for a sexy headline.

Consider this study in the current issue of Science: “A Method for Building Self-Folding Machines.” A bit bland, you’ll no doubt agree. A Real-Life, Origami-Inspired Transformer is how the journal’s public affairs department referred to it. Now that’s more like it.

It’s now possible to print electronic circuits on a flat sheet of paper. So if you use some clever folding techniques (based on the ancient art of paper folding called origami), you can fold these sheets into useful structures — maybe a crab-shaped robot that could scuttle across the floor, or a swan-shaped robot that could really fly.

 

Kinda like the beastie up above there. The really clever bit was using a thermal-activated material called a shape memory polymer which would cause the paper (or whatever material) to fold as needed. So you basically create flat-pack robots which can be remotely activated into a useful machine as needed.

It’s fun living in the future.

*Named after John von Neumann, who among many other impressive accomplishments was instrumental in developing the concept of  self-replicating machines. The term has been commonly used this way in Science Fiction for decades.



A crack?

Interesting news item on NPR this morning:

Close Encounters Of The Radio Kind? Mystery Bursts Baffle Astronomers

Astronomers have a mystery on their hands. Two large radio telescopes, on opposite sides of the planet, have detected very brief, very powerful bursts of radio waves.

Right now, astronomers have no idea what’s causing these bursts or where they’re coming from. And nothing has been ruled out at the moment — not even the kind of outrageous claims you’d expect to see in tabloid headlines.

* * *

As you would imagine, there’s been lots of speculation about what’s behind these mysterious bursts. Some astronomers think they’re caused by blitzars, pulses of energy from a supermassive star collapsing into a black hole. Others think they may be caused by power solar flares coming from stars nearer by.

And Lorimer says he has to mention it: “There’s even been discussions in the literature about signatures from extraterrestrial civilizations.”

 

From Chapter 1 of  Communion of Dreams when news of the discovery of an evidently alien artifact on Titan is being discussed:

The man sitting next to him got up, stepped up to the holo of the artifact still rotating there in the center. Robert Gish was a little unkempt, his beard untrimmed, his dark hair matted. He was out of shape, almost flabby in appearance. His scientific reputation was as unconventional as his looks. More so. He had been responsible for the radical change in long-range sensing which led to the development of the Advanced Survey Array. Nobel Prize stuff. A true genius, not just brilliant but able and willing to make leaps that took others years to understand. Which was why Bradsen had him here: Gish had been saying for decades that there was other intelligent life among the stars. Saying it so loud and so often that he was considered a crank, since he had no proof and couldn’t even really explain why he believed it to be so, at least in a way that others could accept.

Reaching out as though he was going to touch the object, he said quietly “We know what it is. It is a crack in our shell.”

 

Interesting news, indeed.
