A short essay on variational calculus

In this essay we'll take a brief look at the fascinating musical period between andwhere two important periods overlap and morph: Cultural influences on the Baroque and Classical periods Reason and linear logic.

A combination of many factors contributed to a new awakening, a new re-birth, a Re-naissance, which gained power in Italy around Galileo and Kepler stand out as proponents of the idea that man could understand the world around him by observing phenomena, followed by constructing models describing those phenomena while using mathematics as a descriptive language.

These models are then validated by repeatable experiment, and The model, like the crystal ball of the ancients, will predict the future for us and tell the observer how much time it will take to reach the ground.

The model worked for Galileo when he dropped the stone years ago, as well as today. The models are completely abstract and rational mental operations. The latter is an example of belief in the power of rational thought, which nowadays seems obvious and commonplace, but in perhaps not quite so.

It apparently takes quite a long time for new concepts to comfortably settle in the collective, cultural subconscious. Newton had already disputed the invention of the calculus with Leibnitz and published his Principia Mathematica by the time Bach and Handel were two years old!

But I believe it took a generation for the powerful ideas about rationale and logic to sink in, and that the subsequent rejection of the Baroque and the birth of the Classical musical period could be seen as a cultural byproduct of this so-called "Age of Enlightenment", as the latter gained widespread acceptance, pushing previously held beliefs out of the way and heralding cultural change.

Although the Musical Classical period is of course long gone, we are still witnessing what well may be the dying phase of that Age of Enlightenment, since we've become aware through experience, philosophy and science that rational thought is not the explanation, but merely seems to be one dimension of an answer.

Therefore the next Age may for example well be the "Age of Awareness", driving major c t-family: A Baroque composer may subconsciously have thought of himself more as a spiritual vessel, as a medium or a vehicle i.

The Classical composer in contrast might place more importance on mankind, himself and his work, i. I hasten to add that this observation merely points out possible tendencies and not absolutes.

Consider the arch-baroque Handel, who is apparently worldly and practical - in contrast to Bach - and was often reported to be obsessed with success, rivalries and mundane financial affairs. The themes of the librettos he used though not the oratorios deal mostly with relationships, power and politics, or are staged in the mythical, and not the spiritual realm.

Great fanfare over an angry Zeus or a jealous Juno and so forth. Yet his music often seems to supersede the script and human melodrama, touching on the real drama of existence and so transcending into the metaphysical anyway simply due to the sheer weight and brilliance of his musical mind.

The practical and worldly side of his psyche is also revealed by the fact that Handel would recycle and reuse entire musical parts while making slight changes, in the interest of rapid productivity. Art as a manifestation of world events. To better appreciate a work of art, it may help to have some sense of the main cultural and sociological forces at the time the work was created, i.

Hence this author found it helpful to create a greatly condensed chronological chart of a few important social, artistic and scientific events surrounding those periods.


Transitional periods are colored gray. Philosophers are not listed by birth year, but rather bclose to the median of their productive life, and include mathematicians, natural philosophers i. The hyperlinks may be helpful musical and visual aids, and are underlined in blue.

Euler coined the term calculus of variations, or variational calculus, Stopping short of invoking a god as an explanation, how can we address such an issue? One way would be to ask what a universe without a least action principle would be like.

Euler caught the world's attention by writing a maths essay (there's hope for me yet) which.
