Intelligence of Norwegians and Danes on the wane, say researchers

It *seems* that IQs were on the rise from the 1950’s until about 1995, when the rise stopped and started to reverse, with an annual average decrease of 0.21%. Assuming that’s accurate (IQ testing is notoriously handwavy… it’s supposed to be more or less fixed, but my own tested IQ score went up by twenty or so points between junior high and college. On the whole I trust IQ scores about as much as I trust polygraph testing), the researchers believe that the reason for the dumbening of the Scandihoovians comes down to the fact that schooling changed. Essentially life got easier and less challenging, both in the classroom and in the welfare state as a whole; as a result, brains weren’t challenged and smarts atrophied.

This is not a new idea. Say what you will about the fascists, their idea that life was all about a constant struggle of strong vs. weak should, at least in principal, lead to constant improvement. Of course, the death squads and ever-present sense of DOOOOOOM probably work against actually improving the breed. Soft living has long been seen as not as good as strenuous living when it comes to survivability… not of the individual, family, tribe, nation, race or species. There could well be a lot of truth in that. Being challenged – physically, “spiritually,” intellectually – is almost certainly a good thing. The Moon, Mars, asteroids, moons of Jupiter and beyond won’t be successfully colonized by the lazy, either physically or intellectually, but by those who are willing and able to rise to the inevitable challenges.

An interesting experiment would be to take a statistically valid number of these new, dumber Danes and Norwegians and put them into a rigorous and challenging educational environment and see if that smartens ’em up.

There are a lot of “fail” videos on YouTube. A *lot.* Many clearly document failures, but some show what might look like a failure to a layman but isn’t to someone who understands what’s actually going on. Such as the video below. It shows a Russian 9K22 Tunguska mobile anti-aircraft gun firing on what I presume to be a testing ground. For most of the video the gun is shooting off towards a target off towards the horizon; the tracer rounds seem to have a lot of dispersion, and a lot of them bounce off the terrain or the target and fly off into the sky. Anyone who has seen enough firearms testing knows this is pretty normal, but it might look like a “fail” to a layman. So I was underwhelmed with the failtastic nature of the video. Until about the last ten seconds or so, when the pucker factor went up to 11 and then ripped the knob right off.

This piece of art depicts the McDonnell-Douglas “Drawbridge” orbiter staging off the manned flyback booster, showing the wings still folded against the sides of the fuselage. The wings served no purpose during ascent; they would only be used after-re-entry. Of course, in the event of a mission abort shortly after launch, the wings would need to deploy fairly quickly. There are no doubt numerous abort scenarios where the orbiter would be left intact after separation from a presumably stricken booster (or after a main engine failure on the orbiter stage), but would nevertheless still be doomed due to inability to get the wings deployed in time.

I’ve uploaded the high-rez version of this artwork (5 megabyte 3951×2121 pixel JPG) to the APR Extras Dropbox folder for 2017-12, available to all APR Patrons at the $4 level and above.

Some celebrities claim that they are actually nerds… because being a nerd is, at least for the moment, kinda cool, or at least a way to pretend to connect with a certain portion of the market. And then some celebrities can actually *prove* that they are nerds with video evidence…

If you were wondering what the current limits in 3D-printing resolution are… check this out:

Lithuania sends Pope Francis ‘world’s smallest’ nativity scene for Christmas

So how small is it? Overall diameter is 0.3 mm, and the baby Jesus figure is smaller than a human cell.

Details are sparse, such as what the figures are actually made of, but presumably it’s some sort of resin. I wonder if hard limits are close… not only the wavelength of the laser used, but perhaps even limitations of the material itself. At some point you’re down to molecules, but limits might kick in even before then. How is the resin layered up? Or is the laser focused to an insanely precise point within the resin?
