Another consequence of the crumbling US infrastructure

It is by now pretty much a given that the mania to cut taxes to enrich the wealthy has resulted in government being deprived of the necessary revenue to maintain its existing infrastructure and public spaces, let alone make any improvements to bring them into line with other developed nations. Anyone who has traveled to other developed and even many developing countries will immediately notice the difference in roads, airports, and other transportation systems and how the once-enviable public spaces of the US, such as its roads, parks, and libraries, are slowly decaying.

Anti-vaxxers take aim at Mississippi

Mississippi is a poor state combined with a strong religious tradition and is usually at the bottom of the list when it comes to most measures of social well-being. But there is one area where it excels and that is in the vaccination rate where the rates are the highest in the nation. 99.7% of its kindergartners are fully vaccinated, compared with 94.5% nationwide. I discussed the reasons for this anomaly in a post last year. They achieved it by limiting exemptions from vaccination only under very strict conditions, unlike the much looser exemptions in other states.

Ego depletion theory in trouble?

The field of psychology has been reeling because of problems with replicability, in that studies that claim to see certain effects have later had doubts cast upon them when efforts to replicate them failed to do so. Part of the problem is of course dealing with human subjects. But one of the theories that seemed to be pretty robust was based on a study by Roy Baumenister and Dianne Tice that suggested that people have a finite reservoir of will power and that when that is depleted by using it on some tasks, then we have reduced ability to overcome new challenges until that reservoir is replenished.

The “Rule of Three”

In watching Michael Moore’s film Where to Invade Next that I reviewed here, I was struck by a segment that he had on the role of women in Iceland. In 1980, that became the first country to democratically elect a woman as president of a republic (though not the first country to elect a woman as an executive head of state which happened in Sri Lanka when it elected a female prime minister twenty years earlier) and she went on to serve four consecutive terms. Every major political party in Iceland now requires a minimum of 40% of women members.

The search for pi

Today March 14 is so-called ‘pi day’ where in the month/day format in the US for the date gives 3/14. The number pi (the ratio of the circumference to the diameter of a circle) is a source of endless fascination because it is so basic and yet so ubiquitous in all areas of science and mathematics and everyday life. Here is a fascinating article by Xiaojing Ye on the search for obtaining increasingly precise values of pi. It contained many nuggets of information that were quite new to me.
