Blogging the industrial revolution

Not for the faint of heart, but interesting non-the-less, the Economic History blog has a nice series of posts on articles studying the Industrial Revolution.

This blog summarizes papers published on Economic History in major academic journals. The industrial revolution series includes an interesting post on why the industrial revolution happened in the North and not the South. An article by Earle and Ronald (1980) argues that it was because of the monoculture agriculture (just one crop) in the north, cheap labour was available for industry.

Self-respect rather than self-esteem

[S]elf-esteem is but a division of self-importance, which is seldom an attractive quality. That person is best who never thinks of his own importance: to think about it, even, is to be lost to morality. Self-respect is another quality entirely. Where self-esteem is entirely egotistical, requiring that the world should pay court to oneself whatever oneself happens to be like or do, and demands nothing of the person who wants it, self-respect is a social virtue, a discipline, that requires an awareness of and sensitivity to the feelings of others. It requires an ability and willingness to put oneself in someone else’s place; it requires dignity and fortitude, and not always taking the line of least resistance. – Dalrymple, 2010.

Self-respect is earned, while self-esteem is not. That at least is the argument of Theodore Dalrymple, who defines this interesting distinction between self-esteem and self-respect based on his observations as a prison psychiatrist. What people want is a “just appreciation of one’s own importance and of one’s own worth.” To assume that one is entitled to respect because of one’s intrinsic strengths is destructive because it says that you don’t have to do anything to get respect. But respect is earned. Both importance and worth are values that are ascribed by others, by society, and to earn them requires effort and achievement. Self-respect is the appraisal of oneself based on one’s contribution to society.

It’s an interesting argument in semantics at the very least, but the fundamental argument at least aligns with the proper way to use praise and rewards. By praising the effort you acknowledge the importance of work in achieving goals, building self-respect, rather that praising intrinsic abilities (“you’re so smart”) that engender a sense that the student is entitled to do well.

One has only to go into a prison … to see the most revoltingly high self-esteem among a group of people … who had brought nothing but misery to those around them, largely because they conceived of themselves as so important that they could do no wrong. For them, their whim was law, which was precisely as it should be considering who they were in their own estimate. – Dalrymple, 2010.

Theodore Dalrymple is a conservative in the dictionary sense of the word. He argues the importance of tradition and personal responsibility. He also strongly believes that healthy culture must satisfy the need of people to belong to something larger than themselves. So much so, that despite being an atheist, he argues that religions, some types of religions at least, have an important role in society.

About The Elegant Universe

NOVA’s program The Elegant Universe has an excellent website where the entire three hour video is available for free (with a full screen option). They have also broken the video up into segments and have a great teachers’ page which summarizes what’s in each segment.

The Elegant Universe's Teachers' page is excellent.

Created in 2003, when string theory was making it’s big splash in the popular consciousness, The Elegant Universe starts with Newton’s observations of gravity, shows Einstein’s separate explanations of why gravity works and the nature of the sub-atomic world, and finally delves into string theory which tries to reconcile Einstein’s two theories into a unified whole.

We don’t usually get past Newton in middle school, but this PBS program introduces such a wider and weirder view of the universe that it can help strike the imagination. It also presents complex concepts in an intelligible way.

Half plant – half animal

The sea slug.

Next year we’ll be going into the differences between plant and animal cells, as well as into the differences between plants and animals. There are a number of fundamental differences, starting with the fact that plants can photosynthesize to convert sunlight directly into energy and animals can’t. Except for the sea slug. Sea slugs have found a way to pirate chloroplasts from green algae (found via Immersion Blog).

Chloroplasts are the green cellular bodies (organelles) that perform photosynthesis. The species Elysia chlorotica eats the algae when they are young and instead of digesting them entirely, keep the chloroplasts in their gut.

Young E. chlorotica fed with algae for two weeks, could survive for the rest of their year-long lives without eating – Brahic, 2008

What’s even more intriguing is that there is evidence that the sea slugs have incorporated parts of the algae into their own DNA so they can maintain the right conditions for the chloroplasts to survive in the new host (Rumpho et al., 2008). The Sea Slug Form has a nice page on other solar-powered slugs.

Mathematics in the natural world

Mathematics is the language of science. Scientists refine and refine their observations of the complexity of the natural world and try to boil these complex observations down to simple relationships, relationships that are expressed in mathematics. This, I think, is part of the human condition. Our brains are designed to extract simple relationships, heuristics, rules of thumb, from the observations of our senses. It is why Einstein’s equation, E=mc2, has captivated our imagination for so long, why physicists struggle to find the unified theory, and why fractals are so fascinating.

Cristóbal Vila’s short video (found via The Daily Dish) captures some of the magic of the relationship between mathematics and the world.

Meanings

Humpty Dumpty sat on a wall;
Humpty Dumpty had a great fall.
All the King’s horses
And all the King’s men
Couldn’t put Humpty together again!

I often tell my students that the meaning of a piece of literature, or really any piece of art, depends both on the intended meaning of the author and the experience-colored interpretation of the observer; any piece can have as many meanings as there are observers.

We also sometimes talk about the multiple meanings the author may be trying to convey; when they use metaphor in a single sentence or thread subtle, acerbic, poignant satire through a piece.

I can’t remember ever getting to the point of talking about unintentional meanings that seep into the work from the author’s unconscious, but these, sometimes I suspect, tell us the most about the nature of our shared humanity than intended meaning can.
