Shedding light on Daylight Savings Time

The practice of shifting clocks twice a year is an annoyance to everyone. Its roots go back to the Enlightenment, when such luminaries as Ben Franklin suggested the practice in part to keep urbanites, who lived by the clock, in better summertime sync with the rural majority who lived by…

Trying to teach art at a dysfunctional public grade school

“If I didn’t care about my kids, I’d have an easier time.”

“No real-life problem is ever actually solved, it seems.”

For three years, Geri Anderson has worked as a grade school art teacher. She wakes up every day, willing to try her hardest to make a difference in the lives of the students who attend Walnut Elementary School.  “Geri” and “Walnut” are not real names; Geri and I decided to use these pseudonyms to allow Geri to speak freely. Everything else in this article is based on my recent interview of Geri. 

Geri is a soft-spoken woman in her mid-twenties.  Before being hired for her current job, Geri often substitute taught at expensive private grade schools.  She took her first permanent job at Walnut to make a difference. 

Geri teaches art to each of the 200 students who attend Walnut.  They range in age from preschoolers to sixth-graders. The average class includes about twenty children, although some of the classes have almost 30 children.  Not all of the teacher positions are filled at Walnut; for many months, the school has sought the help of adults from the community to fill in for the non-existent science teacher, for example. 

Walnut is located in the urban center of a large U.S. city.  98% of the children attending Walnut Elementary are African-American.  More than 90% of these students receive free or reduced price lunches.  Based upon Geri’s observations, the great majority of the students live in single-parent homes.  Classroom behavior issues, including …

Why can’t I get that song out of my head?

I might owe some people an apology.  

I recently posted about a song from “Scrubs the Musical,” a television episode that aired a few weeks ago.  The title of this tune is presumably “Everything comes Down to Poo.”  It is a clever and funny tune, but it is also dangerous.

For me (hopefully not for you) that song morphed into an “earworm,” another name for a song that can get stuck in one’s head.  This crazy tune from Scrubs has been following me around relentlessly for the past two weeks.  It has sometimes been distractingly annoying during the day.  It even kept me awake one night last week.

What to do?  I just happen to be reading a cogsci/music book: This is Your Brain on Music, by Daniel Levitin. Here’s what I learned from Levitin: There is relatively little scientific work done on the topic of earworms.  What is clear is that

musicians are more likely to have ear worm attacks than non-musicians, and . . . people with obsessive-compulsive disorder (OCD) are more likely to report being troubled by ear worms—in some cases medications for OCD can minimize the effects.

Hmmm . . . This makes me wonder whether Walgreens carries any over-the-counter medications for OCD . . .

Levitin suggests that the neural circuits representing a song somehow get stuck in “playback” mode, but usually only a small fragment of a song (15 to 30 seconds) is involved.  Ear worms are most likely “simple songs and commercial jingles.”…

The Semantics of Secular Labels

Ever since I started doubting the existence of God, I have frequently encountered confusion between the numerous labels used to describe non-theistic belief systems. This is most commonly seen between the words “atheist” and “agnostic,” both of which signify the absence of definitive belief in a deity. At first glance, the distinction may seem obvious: an atheist disbelieves the existence of God or gods, while an agnostic believes that it is impossible to know whether there is a God and thus refuses to commit to either belief system. However, in reality these two terms tend to overlap to the extent that two people holding exactly the same (non)belief may label it differently, one identifying as an agnostic and the other, an atheist. Further, one’s label of choice is heavily influenced by the public perception of these terms, the word “atheist” being the more pejorative of the two in the eyes of the public. This probably convinces many non-theists to describe themselves as “agnostic,” as this label seems more palatable and less presumptuous than “atheist.” If one carefully examines the definitions of these terms, however, one should become more hesitant at rejecting one label for another.

I will begin my exposition by quoting from Bertrand Russell’s 1947 pamphlet, Am I An Atheist Or An Agnostic?

[. . .] As a philosopher, if I were speaking to a purely philosophic audience I should say that I ought to describe myself as an Agnostic, because I do not think that there is a
