Recently finished, and much enjoyed, Dr. Robert Lustig’s latest volume on nutrition/health/food, “Metabolical,” a fairly searing take on the American diet and how it got to be this way. Toward the end of the volume comes this passage hinting at the insidious countervailing pressures at work:
“Which addictive substance is the cheapest to produce and procure, yet the most expensive burden to society? Nicotine used to be the cheapest. At its worst, lung cancer claimed 443,000 people a year and cost healthcare $14 billion annually. But it also made the U.S. government lots of money, because the median smoker died at age sixty-four, before they started collecting Social Security and Medicare….”
[he goes on to dispatch with alcohol in a similar vein, before coming to his conclusion that “By far and away, the most expensive burden to society is sugar,” which he has spent much of the book detailing].
Not terribly mathematical (though plenty of facts and figures), but a good, if scathing, read on processed food in America.
"Dimension"... like many intuitive ideas, not so easily defined and grasped:

This is old (…well around 5 years old), but Cliff Pickover retweeted one of my favorite static illusions yesterday, the “Scintillating Grid Illusion” by gamer Will Kerslake. The grid contains 12 black dots at intersections but you can’t see them all at the same time! Be befuddled:
Here’s one piece on it:
...shortly after preparing the above post yesterday, I then came across this Tweet introducing me to the Ames Window motion illusion, which was possibly new to me (and definitely worth checking out if you're unfamiliar with it):
