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.

I should have some interesting news to share in a couple of days. But for now, I thought I would share this amazing post from Phil Plait at Bad Astronomy:
Yesterday, I posted an amazing Hubble Space Telescope picture. I don’t think it’s too soon to post another shot from Hubble… and I think you’ll agree when you see it, especially after you get an understanding of what you’re seeing.
And as Plait notes, that’s the low-resolution image.
Go enjoy the article, and marvel at the images he has/links to. Seriously — it is worth your while, if you’re any kind of a space-geek at all.

A mix of little things, playing catch-up for the last couple of weeks …
Why catch-up? Well, this might explain why I took a break for a while there.
And we’re off …

First thing, thanks to all who downloaded Communion of Dreams over the weekend, or helped to spread the word about it. There were a total of 693 downloads worldwide — and that includes various European portals, as well as Canada, India, and Japan! Pretty cool.
For those who have gotten the book, once you have a chance to read it please take a few moments to review it on Amazon or elsewhere – it really does help, and as I am finishing up writing St Cybi’s Well the feedback is most welcome.

Wow.
Go see the full size image and explanation of the science. Worth it.

An excellent read by an old and dear friend: There’s an App for That: Cancer in the Modern Age

And another excellent read, all in all. But this paragraph is so painfully true:
“Writing is a strange and solitary activity. There are dispiriting times when you start working on the first few pages of a novel. Every day, you have the feeling you are on the wrong track. This creates a strong urge to go back and follow a different path. It is important not to give in to this urge, but to keep going. It is a little like driving a car at night, in winter, on ice, with zero visibility. You have no choice, you cannot go into reverse, you must keep going forward while telling yourself that all will be well when the road becomes more stable and the fog lifts.”

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.
Filed under: Astronomy, Bad Astronomy, Phil Plait, Science, Slate, Space | Tags: asteroid, Astronomical Unit, astronomy, Bad Astronomy, Douglas Adams, fear, Hitchhiker's Guide to the Galaxy, jim downey, Light-year, Moon, Phil Plait, science, Slate, space, UR116, Wikipedia
Phil Plait has another in a long series of articles about a space rock that isn’t going to hit Earth. Seriously:
This is Part N of what is apparently an infinite series of “No, Asteroid XXX Is Not Going to Hit the Earth” posts.
I’m sure he’s right. I have no doubt that he’s right. The latest rock in question isn’t going to get any closer than about 5 million kilometers. Which, as Plait notes: “That’s a pretty wide margin, well over 10 times the distance to the Moon.”
But I think that the problem with this kind of thing is that most people just have no clue how great that distance actually is. Seriously. I remember reading that a series of studies were done where if you asked people what they thought of the relationship between the Earth and the Moon was in terms of distance, where the Earth was represented by a basketball and the Moon by a softball, they’d typically say that the distance between the two was about a foot. Some would say a yard. As in, 3 feet. Maybe they’d say a meter if they were feeling sciency.
Whereas the proportional distance would be more like 24′ in actuality. (Based on just memory, I originally said 18′. A friend who actually knows this stuff gave me the correct number – thanks, Brent!)
Space is big. Most people have no damned clue how big. So when you say that some fast-moving rock will pass by the Earth by as much as 10x the distance of the Earth to the Moon, they’ll get scared, thinking that it is going to be a hell of a lot closer than it actually is.
It’s all a matter of perspective, not science. Like most things.
Jim Downey
Edited to add: My friend Brent, who set me straight on the actual proportion above, added a comment on FB to note that if you have the distance of the Sun-Earth (one AU) set to one inch, then a full light-year would be right about a mile total distance. Which would put our nearest neighboring star at about 4.5 miles distance.
Yeah, space is BIG.

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.

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 …

… St Cybi’s Well, what with an incompetent theocratic government in place:
So imagine the scenario. A deadly flu pandemic is beginning in the northeast. TSA agents are asked to report for work in the germ incubators that are airports to keep the transportation system running. And while their bosses in Washington, D.C. can’t supply them with reliably functioning respirators to protect them from infection, they’re keeping thousands that may not work on hand, thinking they may hand them out for “employee comfort,” like security theater karma for those who make us remove our shoes and take our water.
But sadly, scarily, it isn’t. Rather, that passage is from the following news item:
The Department of Homeland Security Is Not Prepared for a Pandemic
As the Department of Homeland Security endeavors to prevent another 9/11, a terrorist attack that killed nearly 3,000 Americans, it is worth remembering that there are far deadlier threats out there. I speak not of ISIS or Ebola, but the influenza virus. The flu pandemic that began in 1918 killed 675,000 Americans. That is to say, it killed about as many Americans in a couple years as the AIDS virus has in decades. Worldwide, that same flu pandemic killed an estimated 30 to 50 million people. It would take 16,000 attacks like 9/11 to equal that death toll. Those figures powerfully illustrate the case for redirecting some of what the United States spends on counterterrorism to protecting ourselves from public health threats.
Of course, money only helps if it isn’t squandered. Take the extra $47 million dollars that Congress gave the Department of Homeland Security in 2006 to prepare for a pandemic. As a recent Inspector General report explains in depressing detail, a lot of that money was wasted. And one darkly hilarious passage in the audit reveals what may be the most galling example of security theater ever.
Oh, joy.
But it’s OK, because the rest of the world is ready to step up and fight against a viral threat which could explode into millions of cases in just a few weeks, right?
Um …
Dire Predictions On Ebola’s Spread From Top Health Organizations
Two of the world’s top health organizations released predictions Tuesday warning how bad the Ebola outbreak in West Africa could get.
Both the Centers for Disease Control and Prevention and the World Health Organization agree that the epidemic is speeding up. But the CDC’s worst-case scenario is a jaw-dropper: If interventions don’t start working soon, as many as 1.4 million people could be infected by Jan. 20, the agency reported in its Morbidity and Mortality Weekly Report.
*sigh*
Sometimes it feels less like I’m writing a cautionary work of fiction and more like I am looking back and writing an historical account …
