Lemmings and Luxury

A rather nice session at gym this morning. The educationalist absence continues and being tuesday the overall density if decreased. The amusement was rather good as well, being a combination of science podcasts and the galgenhumor of the ongoing partisan suicide in the District over the debt ceiling. In the first instance some amusing pieces about the mechanics of coral structures and the intelligence of parrots, who I was reminded do not sing but make ‘other’ noises, and in the second a lot of noises but all joined in the backlash to be expected against political parties in general when the cost of living skyrockets and an even worse depression seizes the circulatory system of the nation.

In that light of partisan lemmings, I have a couple of articles that seem to be paradigms of things likely soon to be dusty memories. First, I see a PEW article [Link] about the ownership of eReaders and Tablets. The graphic

is telling. I have to admit to sufficient economic ignorance as to whether these fractions are consistent with pricing expectations. After all, eReaders run 0.33 – 0.5 of the cost of a tablet. Perhaps more pointedly, the curve possibly indicates a saturation of the tablet market?

What is not told is what is the overlap. How many own both? All we can say from this is that somewhere between 0.12 and 0.2 of Amerikan adults have the capability to read eBooks (if we exclude conventional boxes.) Since only 0.5 of that same demographic read books, which gives us a lower limit on the bog fraction, that puts the eBook fraction at double those bounds, 0.24 – 0.4, which seems a bit at odds with the claim of selling more eBooks than pBooks by some retailers. Do I sense the aroma of rattus Norwigica?

Next, I ran across an article [Link] about a study at the campus of the Black Warrior that indicates that children between the ages of 7 and 10 years of age who suffer from Attention Deficit/Hyperactivity Disorder cannot be entrusted to cross streets safely. Apparently the problem is that while the children look both ways as prescribed by doctrine, they underestimate either time of transit of time to collision with oncoming motorcars. This implies poor spatial comprehension or poor temporal comprehension, or both. Such acomprehension is common in humans, as evidenced by the shoddy driving skills exhibited by adults resulting from poor estimation of velocity and distance. In addition, symptoms of attention deficit are common in adults driving motorcars, so this carry over could be explanatory of why driving is so unpleasant and risky these days.

What do these have in common? They are things studied that will be faint memories after the collapse of the national economy next week, things to be viewed in future as luxuries no longer affordable.
