Photo of Earth by Nasa? Nope. Astroengineering.
Is this a photo of Earth by Nasa? Nope. In this artist’s conception, the Moon is geoengineered/astroengineering by an advanced civilization to be more like Earth. Will inducing artificial earthquakes through geoengineering or someday save lives, or is it too dangerous? Will we someday geoengineer the and the stars, as discussed on recent science documentaries? These were discussed in our earlier blog post on fracking and geoengineering, for which this was the featured image.

Although we’ve certainly done multiple articles on this before, second reader question on “how do I control my indoor air quality” means it’s time for another blog post on air quality technology. I live in San Fransisco where the air is not particularly good. How do I protect my newborn baby? I’m worried both about dust from cars and blowing over from China as well as chemical emissions from our new rugs and paint. Another reader: I’ve come down with allergies. Taking control of my indoor air quality now sounds very appealing. Automobile exhaust probably responsible for some “allergies” Kudos to you for trying to take control. Funny thing about allergies: we’re getting anecdotal evidence from family and friends that all of this technology is somewhat new to the medical community as well (at least the concept that it so affordable anyone can just go out and buy it). We have friends and relatives that for years were diagnosed with minor “allergies” that everyone (including the doctors) assumed were minor pollen allergies.… Read the restError bands, or why models will be models (of the mathematical variety)
In response to our article on the Social Progress Index (SPI) and prediction markets, the Social Progress Index folks asked why we didn’t just stop at optimizing the SPI. Two reasons, we said: (1) There’s an unfortunate tendency of people to believe (math) models are reality. They’re just models with error bands. (2) There’s going to be politically-motivated suspicion of any model (as well as political-motivated attempts to manipulate models and their interpretation). [For our readers coming over from our fashion design section, or our earlier article on virtual reality fashion models and modeling, we are talking about mathematical models here.] So how do models go bad? Let’s use the Social Progress Index as an example. We talked elsewhere about the tension between things like freedom of press and national security in a model like this. (In general, such tension will exist in an useful economic or financial model. If the tension did not exist, there would be nothing interesting to optimize, and so need for such a model in the first place.)… Read the restRecent Posts
