Is there life on Mars? Atmospheric methane says ‘maybe’

4 Comments

MarsAfter last year’s long-awaited confirmed discovery of water on the red planet, David Bowie comes another step closer to finding the answer to his question: NASA called a press conference today to announce that they have, in partnership with some university science teams, “achieved the first definitive detection of methane in the atmosphere of Mars”.

So what’s the big deal with that? Basically, there’s two reasons you might find methane in a planetary atmosphere: geological activity or biological activity. It’s going to take a lot more work to discover which of the two is the culprit in the case of Mars (and the NASA announcement does a better job that I can of explaining it all), but either option is pretty exciting to space nerds… after all, it’s not all that long ago that we pretty much assumed the whole planet was inert.

And as a side-tangent, this is great political timing from NASA, whether accidental or deliberate – with a new president about to enter the White House with promises to shake things up, announcements like this get everybody talking about space with that old-school sensawunda I remember from my childhood… and given the bleak state of the news headlines at the moment, something to make us look up from the mundane for a moment can only be a positive. Something big to dream about. [image by chipdatajeffb]

I mean, just think – life on Mars! It’s like something out of a science fiction novel, isn’t it? 😉

How to Communicate More Effectively, Part 5 – Build Conviction

[How to Communicate More Effectively is a series of guest posts from Gareth L Powell. In case you missed ’em, here’s part 1, part 2, part 3 and part 4.]

Making your audience want your product is one thing, convincing them to actually put their hands in their pockets is quite another. You have to get over their natural reluctance to buy or act. This can be done in a number of ways, the most common being the testimonial and the product comparison.

Testimonials are short quotes from celebrities or satisfied customers endorsing the product. Including one or more of these helps to reassure the reader that their decision to buy from you or use your service is a wise and sensible decision.

Comparing your product with a more expensive option also helps to encourage the conviction that the decision is correct.

Similarly, if you’re in a position to offer any sort of guarantee (“Your money back if not 100% satisfied) then this is the place to do it.

Do novels help our morals evolve?

Victorian era typewriter keysAre there hidden messages and subtexts in stories and novels that help reinforce and strengthen the values our society holds? A group of evolutionary psychologists researching Victorian-era fiction suggests that the classics of the time…

… not only reflect the values of Victorian society, they also shaped them. Archetypal novels from the period extolled the virtues of an egalitarian society and pitted cooperation and affability against individuals’ hunger for power and dominance.

[…]

The researchers believe that novels have the same effect on society as oral cautionary tales of old. “Just as hunter-gatherers talk of cheating and bullying as a way of staying keyed to the goal that bad guys must not win, novels key us to the same issues… “

The idea of culture as societal regulation valve is nothing new, I suppose, but it seems the researchers were focusing on the canonical literature of the era rather than what would have been considered popular by the man on the street. What about the Victorian precursors of the pulp magazines, for example, or their oft-unmentioned love of porn and erotica? There was a very different set of values embedded in those, I think we can assume…

That said, I think there’s probably a nugget of truth in the assertion that art contains coded value systems from the society that produced it. So what does that mean for us 21st Century types? We have somewhat different values nowadays, and we no longer have such a dominant monoculture as the Victorians. [image by k4chii]

Looking back on the science fiction novels we’re reading today, what would an anthropologist or evolutionary psychologist from a century in the future make of our values?

Death and taxes – IRS advises taxing metaverse economies

1 Comment

raining money in Second LifeNo one but their creators can be entirely sure of how much money is sloshing around in the economies of MMOGs and metaverses like World of Warcraft and Second Life, but given the sheer number of regular participants in both (and the brisk markets for in-game items using real world money) it’s certainly not pocket change.

That’s probably got a lot to do with why the United States IRS is being advised to start taxing virtual economies:

“Economic activities associated with virtual worlds may present an emerging area of noncompliance, in part, because the IRS has not issued guidance about whether and how taxpayers should report such activities,” Olson wrote in her report. She points out that almost all income is subject to tax—even prizes, winnings, and barter exchange. She also acknowledges, however, that tracking and reconstructing so many tiny transactions would be a huge burden, and that attempting to place a value on virtual transaction could present serious challenges.

No kidding; brief and silly scares about terrorist money laundering aside, the potential of black and grey economies lurking in the metaverse is pretty obvious. But considering how easy it seems to be for the meatspace megarich to slip through the net, is this going to prove too tough a nut for the IRS to crack?

For example, when does the money become taxable – when it leaves the virtual space in question, or as soon as it is earned by a citizen? What happens when exchanges operate between virtual worlds? Will the new offshores be based on server farms as opposed to Caribbean islands?
