Anyone who has ever had a hard drive crash on ’em knows that “data storage ain’t forever.” But how about 300 million years?

Data Saved In Quartz Glass Might Last 300 Million Years

Hitachi has developed a system that uses a femtosecond laser to etch microscopic dots within (note: *in*, not *on*) a sliver of quartz 2 cm wide and 2 mm thick. The data density is somewhat better than for a CD; the prototype withstood several hours at 1,000 degrees (F or C, not given). Resistant to chemicals, proof against water. Data would be safe for as long as the quartz wasn’t mechanically ground up into glass… hundreds of millions of years being a possibility.

Life is full of disappointments. One that has grated on me for decades is the lack of a decent comet. I can just barely vaguely remember people being cheesed off about Kohoutek… it was hyped, but failed to deliver. Then Halley, which I was unable to see even with a telescope. The supposedly Great Comets Hyukatake and Hale-Bopp were dismal failures… sure, I could see ’em with the naked eye, but only if I knew exactly where to look and didn’t mistake ’em for faint wisps of smoke. Feh.

Two comets have been recently discovered that will round the sun in 2013, and the press is already trying to ramp up excitement.

Comet C/2011 L4 (PANSTARRS) was discovered in 2011, and will round the sun March 10, 2013. it will be low in the sky for those in the northern hemisphere, but will get higher as it moves away from the sun.  It might put on a show. See the JPL orbit diagram HERE.

C/2012 S1 (ISON) has the potential to be spectacular. Discovered last September, its orbit indicates that it is an Oort cloud object on its very first fall around the sun, which *should* mean that it is loaded with frozen volatiles such as water, ammonia, etc. It’s also coming incredibly close to the sun… perihelion on November 28 will be only about 700,000 miles from the surface of the sun, which should roast the hell out of the thing. On it’s way out, it will pass about 0.42 AU from Earth on December 26… nicely visible from the northern hemisphere. And then on January 14, 2014, Earth will pass through the orbit of the comet, which may result in a meteor shower. See the JPL orbit diagram HERE.

ISON has the greater potential for awesomeness. Additionally, the orbital elements are similar to those of the Great Comet of 1680, which is an encouraging sign.

In order to assure safe staging, the first stage of the Saturn V was equipped with eight solid retro-rockets, paired behind the F-1 engine fairings. Each rocket weighed 504 pounds, of which 278 pounds were propellant, and produced an average of 87,913 pounds of thrust for 0.633 seconds.

Details are sketchy, but it appears that the retro-rockets simply blasted through the fairing. Given the expendable nature of the S-IC and the distance to the S-II stage, the damage this would do and the shrapnel it would throw out would be pretty meaningless.

America’s Real Criminal Element: Lead

In short: it appears that pumping vast amounts of a toxic heavy metal into the air might not have been a good idea. Numerous lines of evidence suggest that high leaded-gas use led, a generation later, to high crime rates; the reduction and elimination of leaded gas a generation ago led in part to the reduced crime rates seen today.

Not a really shocking hypothesis, but the correlations seem pretty convincing.

All over the news tonight are reports of the Steubenville case: in short, some high school football players apparently drugged a girl into unconsciousness and then raped her, and then a bunch of their buddies laughed about it. But like many modern mechanized morons, they thought it would be a good idea to photograph and video themselves doing this, then posted that stuff online, and then yapped about it on Facebook.

As I said, morons.

Much of this information, though, would not have come to light had it not been for the hacker group “Anonymous.” They took it upon themselves to hack email and Facebook accounts, gathered this incriminating evidence, then presented it to the world. What Anonymous did was probably illegal. And I say, good on ’em.

I think what we’re seeing here is a part of a gradual cultural evolution. When I was high school age (long, loooong ago), there were, as there are now, the jocks and the nerds. Feel free to speculate which camp I was in. If you said “jock,” well, no, not so much. Back then, there was no internet that we were aware of; no social media. Hackers existed but were a very specialized rarity. It was very much the jocks world… a world of physicality and no recorded evidence. Jocks, of course, ruled. If you were a nerd (or, let’s face it, a girl), watch out. Unpleasant as those days were, they did nevertheless teach important lessons. If a jock liked to punch you in the hallway during the rush hour between classes, a thin wood plate under your shirt served as a deterrent… especially if it was covered in thumbtacks. Fighting back *physically* was often the fast road to a  serious beatdown… but if you learned to talk right, you could come out ahead. If you learned to speak the right words in the right tone so as to inspire utter terror, you could utterly upend the thug/victim relationship.

But of course, that all came with great risk. An important lesson that many a nerd-who-fought-back learned, you either won and won decisively, or you simply pissed off your tormenter. And so for many on the non-thug end of the social scale, hiding or otherwise keeping ones head down was the tactic most often employed.

Kids today, however…

Now as then, the body-proud thugs are *generally* really quite stupid. Even if their brains are actually wired for smarts, for those to whom success comes not from thinking but from nearly pure physicality – or even just from winning the genetic jackpot and being physically very attractive – there is no *need* to develop their minds. And so… stupid. And so they record their crimes. And so they joke about their crimes publicly. When they are constantly touted by their peers and their community as being heroes, even though all they do is play childish games, that evolved stupidity gets married to a sense of entitlement. Put that all together and you’ve produced a monster.

But now the monsters live in the world the nerds built. More, while the monsters know how to *use* the various technologies that are available, the nerds *understand* the technologies. Nerds are gaining the upper hand. And the beauty of it, the beauty that Anonymous demonstrates, is that now the nerds can fight back… and the monsters don’t know who’s doing it. Hell, it could be a nerd on the other side of the planet. So even if the monster lashes out and threatens or even hurts people… he’s not only not going to shut down his opponent, he’s actually just adding to the pile of evidence that will be used against him.

And so now we have some jocks-turned-monsters who thought it’d be fun to rape a girl. This is one of those things virtually *designed* to piss off nerds. Jocks can easily Get Some. Nerds… can’t. Humans are what a million years of evolution have made us, and the big caveman necessarily is more appealing to the female than the scrawny (or fat) weakling. Fair enough. But when those who could easily Get Some because there are girls willing and eager to Give It Away decide, instead, to Steal It… for those from whom “Getting Some” is a distant and forlorn hope that’s just too damned much to bear. And so, the nerd dreams of being the hero riding in on his white horse to slay the monster and rescue the damsel in distress. Hell, the subset of Anonymous that focuses on going after rapists even calls themselves “Knight Sec“.

Wanting to be a hero to me sounds good and proper (as opposed to… what? Wanting to be a monster? A victim? A bystander?), but it is an attitude that is often sneered at. Look at the sarcastic nastiness tossed towards people who carry concealed, for example. But actually riding to the rescue of a damsel in distress is of course often impossible. Often, the distress is already over; there’s no rescue possible. But the monster remains at large. The monsters chuckling buddies remain at large. Bringing them to justice is a worthy goal… not only to bring them punishment, but to bring a small measure of closure to the victim… and to keep there from being more victims in the future. And dredging up information is something nerds *can* do. Dig through the muck, find the evidence and plaster it all over CNN.

With luck, this sort of thing will only grow. With luck, the nerds will take down many a rapist and their cohorts. Lock them into prison at the age of 18 and keep them there till they’re 50, and you will do the gene pool a *world* of good. Keep taking down monster jocks, and perhaps people will finally come to realize that watching a few kids run around on a field or a court is just not all that important. If *half* the money and effort that goes into football and basketball went into readin’, writin’, ‘rithmetic, science and industrial arts, the United States could end the energy crisis in a single Presidential term, and could colonize Mars by the end of the decade. Glorifying athletes produces… what? Kids that want to be athletes. OK, fine… but that doesn’t bolster society in any meaningful way. If those kids were instead to grow up to want to be metallurgists or electricians, physicists or scientists, entrepreneurs or technicians… wow. What a world this could be.

Rant over.

Neat!

A Radio-Optical View of the Galaxy Hercules A

The elliptical galaxy was photographed by the Hubble Space Telescope in visible light. The violet jets are radio images made by the Very Large Array. The galaxy is two billion light years away; the jets stretch more than one and a half million light years. The power source for this is a giant black hole with a mass 2.5 billion times greater than the Sun.

Higher rez at the link.

The universe is, in the strictest sense of the word, fricken’ AWESOME.

When debating what space tour you will spend your millions on, don’t forget the trip to the Moon offered by Excalibur Almaz. Conveniently located on the Isle of Man, EA apparently already owns four spacecraft (Soviet-era Almaz  capsules, to be married to all-new service modules) and two Salyut space station modules.

Beyond your standard hum-drum one-week trip to a low Earth orbit space station, EA is also touting a mission around the moon (though not yet do to a landing on it). According to the Bbc, EA suggests that such a trip would cost £100,000,000.

I’ve opened a store on zazzle.com to sell posters of my photos. A good thing about zazzle is that they allow customers to select the size of the poster they want. So while the images I’ve uploaded so far (my creakingly slow rural internet connection makes this a long process, given that the images are up to 50 megabytes) are all baselined for 36X12 panoramas, you can select… pretty much whatever size you want.  When I upload the photos, the system generally assumes, based on the size of the images, that I want ’em to be 60X20 inches, so you can go at least that big.

I’m starting off with the 36X12 panoramas. If there are any photos I’ve posted over at the photo blog or elsewhere that you’d really like to have, let me know.

http://www.zazzle.com/scottlowtherphotos

More have been added (it takes a while for the store to update) and more will be added.

In addition to being able to select the size of the print, you can also select the quality of the paper. So, you get a range of options from this:

to…

to…

to…

to…

Me, I’d recommend the larger sizes with the better paper. Because, you know, I’d make more off of those than the smaller versions. But whatever seems best to y’all…

Remember, it’s never too early to start shopping for Christmas! Only 2,182 shopping days until Christmas, 2018!
