Don’t get me wrong — that’s extremely cool technology. And I can think of all kinds of incredible applications even just as it is, let alone what it promises for the future.
But it also gives me the heebie-jeebies watching it move.

Watch a laser beam bounce:
From the YouTube description:
A video captured by Washington University’s Lihong Wang’s new imaging system, known as “compressed ultrafast photography,” shows a laser pulse propagating in air and being reflected from a mirror. The movie is slowed down 10 billion times to make it visible to the human eye. (Video courtesy of Washington University in St. Louis)
A good article explaining this new technology is here:
New Ultrafast Camera Invented At Washington University Could Help Turn Science Fiction Into Reality
Very cool. Take-away quote:
Wang’s new technology improves on previous ultrafast cameras in two important ways.
Up until now, streak cameras could only take a one-dimensional snapshot ― think of it like trying to take a picture of something flying by really fast behind a vertical slit.
And the fastest cameras had to have an external light source to work.
Wang’s technique doesn’t need special lighting, and it produces two-dimensional images ― more like a regular photograph ― but at a rate of one every 10 trillionths of a second.
Damn, that’s FAST.

A very insightful essay into the role which speculative fiction played in the Victorian era, and how it is still echoed in our fiction today: Future perfect Social progress, high-speed transport and electricity everywhere – how the Victorians invented the future
Here’s an excerpt, but the whole thing is very much worth reading:
It’s easy to pick and choose when reading this sort of future history from the privileged vantage point of now – to celebrate the predictive hits and snigger at the misses (Wells thought air travel would never catch on, for example); but what’s still striking throughout these books is Wells’s insistence that particular technologies (such as the railways) generated particular sorts of society, and that when those technologies were replaced (as railways would be by what he called the ‘motor truck’ and the ‘motor carriage’), society would need replacing also.
It makes sense to read much contemporary futurism in this way too: as a new efflorescence of this Victorian tradition. Until a few years ago, I would have said that this way of using technology to imagine the future was irrecoverably dead, since it depended on our inheritance of a Victorian optimism, expressed as faith in progress and improvement as realisable individual and collective goals. That optimism was still there in the science fiction of Heinlein, Isaac Asimov and Arthur C Clarke, but it fizzled out in the 1960s and ’70s. More recently, we’ve been watching the future in the deadly Terminator franchise, rather than in hopeful film such as 2001: A Space Odyssey (1968). The coupling of technological progress and social evolution that the Victorians inaugurated and took for granted no longer seemed appealing.
I think this is very much why many people find that Communion of Dreams seems to fit in so well with the style of SF from the 1950s and 60s — in spite of being set in a post-apocalyptic world, there is an … optimism … and a sense of wonder which runs through it (which was very deliberate on my part). As noted in a recent Amazon review*:
James Downey has created a novel that compares favorably with the old masters of science fiction.
Our universe would be a better place were it more like the one he has imagined and written about so eloquently.
Anyway, go read the Aeon essay by (who happens to be a professor at Aberystwyth University in Wales — no, I did not make this up).

*Oh, there’s another new review up I haven’t mentioned.

The reviews have been mixed, but one aspect of the new movie Interstellar is pretty cool: the rendering of the black hole depicted in the movie. Even moreso since it is as scientifically accurate as possible, based on close collaboration with noted astrophysicist Kip Thorne:
Still, no one knew exactly what a black hole would look like until they actually built one. Light, temporarily trapped around the black hole, produced an unexpectedly complex fingerprint pattern near the black hole’s shadow. And the glowing accretion disk appeared above the black hole, below the black hole, and in front of it. “I never expected that,” Thorne says. “Eugénie just did the simulations and said, ‘Hey, this is what I got.’ It was just amazing.”
In the end, Nolan got elegant images that advance the story. Thorne got a movie that teaches a mass audience some real, accurate science. But he also got something he didn’t expect: a scientific discovery. “This is our observational data,” he says of the movie’s visualizations. “That’s the way nature behaves. Period.” Thorne says he can get at least two published articles out of it.
The video is remarkable. Seriously. Go watch it.
And in a nice bit of serendipity, there’s another fantastic bit of astrophysics in the news just now: actual images of planetary genesis from ALMA. Check it out:
A new image from ALMA, the Atacama Large Millimeter/submillimeter Array, reveals extraordinarily fine detail that has never been seen before in the planet-forming disc around a young star. ALMA’s new high-resolution capabilities were achieved by spacing the antennas up to 15 kilometers apart [1]. This new result represents an enormous step forward in the understanding of how protoplanetary discs develop and how planets form.
ALMA has obtained its most detailed image yet showing the structure of the disc around HL Tau [2], a million-year-old Sun-like star located approximately 450 light-years from Earth in the constellation of Taurus. The image exceeds all expectations and reveals a series of concentric and bright rings, separated by gaps.
That’s not computer-rendered theory. That’s an actual image, showing the formation of planets around this very young star.
Wow.

Three weeks ago we started a “small” home repair project.
Well, we thought it was going to be small. And then we discovered the horror within. As I said in my first blog post about this:
When you start a project like this, you don’t really know what you’re getting into until you actually start getting into it.
Boy, howdy.
Well, it became much more of a project than originally envisioned. If you want to know why I haven’t done a lot of blogging recently, this is almost entirely the reason: we wound up replacing everything about the original porch except the two upright posts, and those we altered. We even wound up having to clean up and put aright some of the work which had originally been done to tie in the porch roof to the house roof, which was a real horror.
And when I say that “we” did it, I mean that literally: my wife and I. We actually did every single aspect of the work. My wife is an architect, and we’re both very used to working on smallish practical repairs — the sort of thing you always have pending on a house which is 130+ years old. Had we known that this job was going to turn out being so big, we might have opted to put it off until a contractor we trust was able to work it into his schedule. But once we got started, we were committed to doing the work all the way through, not according to someone else’s schedule. So, we did it.
What follows below is a step by step photo documentation of the work, just for grins. We finished the work this weekend (well, except for the painting, but that’s pretty minor and will get done in a week or so when we have a chance), and I’m really pleased with how well it all turned out. So, if you’re interested, take a look.
And with a little luck this week I’ll get back to a more normal posting schedule.

NASA Eyes Crew Deep Sleep Option for Mars Mission
A NASA-backed study explores an innovative way to dramatically cut the cost of a human expedition to Mars — put the crew in stasis.
The deep sleep, called torpor, would reduce astronauts’ metabolic functions with existing medical procedures. Torpor also can occur naturally in cases of hypothermia.
* * *
Economically, the payoff looks impressive. Crews can live inside smaller ships with fewer amenities like galleys, exercise gear and of course water, food and clothing. One design includes a spinning habitat to provide a low-gravity environment to help offset bone and muscle loss.
Hmm … seems that I’ve heard of something like that before …

Another interesting item about developing the technology to create a useful swarm of small robots:
Harvard Researchers Create a Nature-Inspired Robotic Swarm
Some scientists believe that the way to solve the flocking enigma is to replicate it. Researchers at Harvard University’s Wyss Institute and School of Engineering and Applied Sciences (SEAS) recently developed a micro-scaled robotic technology that enables a controlled, flash mob–like assembly. In August, the team led by Harvard computer-science professors Radhika Nagpal and Fred Kavli demonstrated the ability of 1,000 robots to self-organize into user-selected shapes, such as a five-pointed starfish and the letter K.
* * *
“Increasingly, we’re going to see large numbers of robots working together, whether it’s hundreds of robots cooperating to achieve environmental cleanup or a quick disaster response, or millions of self-driving cars on our highways,” Nagpal said in the press release. “Understanding how to design ‘good’ systems at that scale will be critical.”
One provocative concept is the possibility of building and infrastructure construction that is carried out by thousands of self-organizing modules. Although many technical hurdles remain, this notion is especially intriguing in the case of hazardous and other challenging settings. In the near term, we will likely witness simple, one-story pavilions built from a collection of mobile robotic bricks to create emergency relief shelters following natural disasters.
Hmm … seems I’ve heard about that idea before someplace. Oh, yeah, from Communion of Dreams:
They were, in essence, enclosing the entire planet in a greenhouse of glass fabric and golden plasteel. It was going to take generations to finish, even using mass microbots and fabricating the construction materials from the Martian sands. Tens of thousands of the specially programmed microbots, a few centimeters long and a couple wide, would swarm an area, a carpet of shifting, building insects. As each cell was finished, it was sealed, joined to the adjacent cells, and then the microbots would move on.
But it is pretty cool to see the work being done to bring that about.
