Four families of equations expose the hidden aesthetic of bicycle wheels, falling bodies, rhythmic planets, and mathematics itself.

The spira mirabilis is a lovely thing, and the equation describing it is simple. He discusses the geometry of four interesting shapes.

I would never claim, however, that math can "expose" an aesthetic. "Expose" is the wrong word, because the aesthetic is immediately apparent, but it's the math that is not.

Coase’s Tortoise - Federal bureaucracy gets in the way of complex ongoing relationships that serve civil society. Most people have heard of Coase's famous theorem, but don't really know it. A quote:

Normal human beings with adult temperaments understand that life is a complex, messy, imperfect business, and that sometimes we have to make accommodation for one another. It is for this reason that modern American English contains the phrase “Don’t make a federal case out of it.” I do not know Mr. Bundy, but, assuming that he is a decent sort, I think it is very likely the case that this story would have gone very differently if one of his neighbors had approached him one afternoon and said, “Say, Cliven, I’m worried that your cattle might step on my tortoises, which are very dear to me. What could we do about that?” Practically every suburbanite with a yard and neighbors with dogs has experienced a comparable situation, as has every urbanite with boisterous neighbors or neighbors who seem to become hard of hearing when their favorite television shows are on. (Ahem.) Our first instinct is not, as a rule, to make a federal case out of it.

If the Desert Tortoise (a fine critter, for sure, and one the Indians liked to cook for supper) survived the buffalo, why not the cattle?

From Eye candy - The pleasure we take in beauty must have been shaped by evolution  - but what adaptive advantage did it give us?

It is not yet clear why adults should find perceptual play fun. Aren’t we done learning how to perceive? Everyone achieves a certain basic level of skill in characteristically human activities: walking, talking, looking, listening, and singing. We do this by pleasurable play when young, and we maintain these skills with practice well into adulthood. But with each of these activities, the human body affords us the capacity to improve – to become extraordinarily skilled. Spontaneously developed language and motor skills are adequate for most purposes, but they are far below those of the most accomplished performers. An accomplished poet or playwright has a command of language that comes from repetition, practice, and instruction. She comes to this level of expertise with great difficulty. The same goes for somebody who appreciates poetry with hard-won knowledge of context and allusion.

I'll give the essay an A- for Effort, but trying to discuss such topics as Truth and Beauty in reductionistic terms is certain to be disappointing in the end. I would argue that the human soul has no adaptive value at all. It's a gift and a curse.

What is the best-adapted and largest class of animals on earth in terms of population, biomass, range, and overall success? Class Insecta. Bugs. Or maybe it's bacteria, but I think I recall that it's bugs. Might have that wrong. It's definitely not the higher apes despite our love of music and our pleasant clothing.

Many bugs make music too.

From Scruton's The great swindle - From pickled sharks to compositions in silence, fake ideas and fake emotions have elbowed out truth and beauty:

Faking depends on a measure of complicity between the perpetrator and the victim, who together conspire to believe what they don’t believe and to feel what they are incapable of feeling. There are fake beliefs, fake opinions, fake kinds of expertise. There is also fake emotion, which comes about when people debase the forms and the language in which true feeling can take root, so that they are no longer fully aware of the difference between the true and the false. Kitsch is one very important example of this. The kitsch work of art is not a response to the real world, but a fabrication designed to replace it. Yet both producer and consumer conspire to persuade each other that what they feel in and through the kitsch work of art is something deep, important and real.

Anyone can lie. One need only have the requisite intention — in other words, to say something with the intention to deceive. Faking, by contrast, is an achievement.

It's all mind-boggling to me. What is outside the universe, or is my sense of space-time too parochial?

Video on the big discovery.

Cosmology is enough to make anybody feel mentally ill, disoriented. The very notions of space-time, and of infinity, scramble my brain and make me think about God.

Here's a good piece on the latest: Proof of the Big Bang - A stunning discovery made at a research station in Antarctica indicates that Albert Einstein was right about the nature of the universe:

 The colossal forces of inflation caused the fabric of space-time – a concept introduced by Einstein as a way of reconciling gravity, motion and time – to start wobbling, like the surface of a sea subjected to an earthquake. One objection to relativity was that no one had evidence that violent events can make gravity form waves like this. Now they have.

Daniel Goldman reviews Joseph Bottum's new book. One quote:

 Joseph Bottum ... examines post-Protestant secular religion with empathy, and contends that it gained force and staying power by recasting the old Mainline Protestantism in the form of catechistic worldly categories: anti-racism, anti-gender discrimination, anti-inequality, and so forth. What sustains the heirs of the now-defunct Protestant consensus, he concludes, is a sense of the sacred, but one that seeks the security of personal salvation through assuming the right stance on social and political issues. Precisely because the new secular religion permeates into the pores of everyday life, it sustains the certitude of salvation and a self-perpetuating spiritual aura. Secularism has succeeded on religious terms. That is an uncommon way of understanding the issue, and a powerful one.
