  1. String theory. In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. String theory describes how these strings propagate through space and interact with each other. On distance scales larger than the string scale, a string looks just ...

  2. Definition The Fourier transform is an analysis process, decomposing a complex-valued function () into its constituent frequencies and their amplitudes. The inverse process is synthesis, which recreates () from its transform. We can start with an analogy, the Fourier series, which analyzes () on a bounded interval [/, /], for some positive real number .

    Commission

    The history of the statue of David begins before Michelangelo's work on it from 1501 to 1504. The commission was made during a decisive period in the history of the Florentine republic established after the expulsion of the Medici. The advantages of democratic government never materialised, and internal circumstances grew worse as dangers from without increased. Lorenzo de' Medici's successors and their supporters were a constant threat to the republic, and it was in defiance of the menace th...

    Process

    Michelangelo regarded a single block of stone as containing all the possible conceptions for a work of art, and believed that the artist's task is sculpting the marble block to reveal the ideal form within, an expression of his Neo-Platonic belief that body and mind are separate, and must work in concert and strive to attain union with one another and with the divine.In later years, speaking of his early commissions sculpting marble, he contended that he was merely liberating figures that wer...

    Placement

    On 25 January 1504, when the sculpture was nearing completion, Florentine authorities had to acknowledge there would be little possibility of raising the 5.17 metre high statue weighing approximately 8.5 tons to the roof of the cathedral. They convened a committee of 30 Florentine citizens that included many artists, including Leonardo da Vinci and Sandro Botticelli, to decide on an appropriate site for David.While nine different locations for the statue were discussed, the majority of member...

    The pose of Michelangelo's David is unlike that of earlier Renaissance depictions of David. The bronze statues by Donatello and Verrocchio represented the hero standing victorious over the head of Goliath, and the painter Andrea del Castagno had shown the boy in mid-swing, even as Goliath's head rested between his legs, but no earlier Florentine ar...

    David the giant-killer had long been seen as a political symbol in Florence, and images of the biblical hero already carried political implications there. Donatello's bronze David, made for Cosimo de' Medici, perhaps c. 1440, had been appropriated by the Signoria in 1494, when the Medici were exiled from Florence, and the statue was installed in th...

    Kathleen Weil-Garris Brandt makes the case that pedestals are of great significance for Renaissance sculpture, and, following Rosalind Krauss, that it is the support, not the statue itself that decides the monumentality of a work of sculpture. She describes how the pedestal that supports the David has been neglected in the literature as a component...

    Officials responsible for the artistic heritage of Florence had become concerned about the David's physical state by the middle of the 19th century. A cleaning of the statue had apparently occurred about 1746, and in 1813 the sculptor Stefano Ricci gave the statue a gentle cleaning and applied a thin coat of encaustic,consisting of beeswax, possibl...
