	Nabla symbol - Wikipedia, the free encyclopedia
		Another, less-common name for the symbol is atled, because it is a reversed delta.
		The nabla symbol is available in standard HTML as andnabla; and in LaTeX as \nabla.
		Nabla is used in mathematics to denote the del operator.

		The Tai-Chi Mandala: The taiji (Yin-Yang) symbol was Bohr's coat-of-arms.
		William Oughtred (1574-1660) was instrumental in the subsequent popularization of the symbol, which appears next in 1618, in the appendix [attributed to him] of the English translation by Edward Wright of John Napier's Descriptio (where early logarithms were first described in 1614).
		The symbol itself is properly called a lemniscus, a latin name which means "pendant ribbon" and was first used in 1694 by Jacob Bernoulli (1654-1705) to describe a planar curve now called the Lemniscate of Bernoulli.

	History of Nabla (Site not responding. Last check: 2007-10-12)
		The symbol, which is also called a "del," "nabla," or "atled" (delta spelled backwards), was introduced by William Rowan Hamilton (1805-1865) in 1853 in Lectures on Quaternions, according to Cajori vol.
		http://members.aol.com/jeff570/m-r.html [from mathword.html] The word NABLA (for the "del" or Hamiltonian operator) was suggested humorously by James Clerk Maxwell, according to one source.
		Thompson (1910) and Andrew Gray, and by Crosbie Smith in "Energy and Empire" (CUP 1989) say something to the effect that the symbol $\nabla$ was invented (c1870) by William Thomson (later Baron Kelvin), as a modification of the symbol $\delta$ which he used for the Laplacian operator.

		The symbols dx, dy, and dx/dy were introduced by Gottfried Wilhelm Leibniz (1646-1716) in a manuscript of November 11, 1675 (Cajori vol.
		Legendre abandoned the symbol and it was re-introduced by Carl Gustav Jacob Jacobi in 1841.
		Cajori writes that Newton's symbolism for integration was defective because the x with a bar could be misinterpreted as x-prime and the placement of a rectangle about the term was difficult for the printer, and that therefore Newton's symbolism was never popular, even in England.

	Tutorial, Electric Geometry - Nabla Del Hamilton
		To try to understand the symbol, one had to examine the conceptual framework Hamilton was working from, and attempt to reconstruct the vision of the world as Hamilton might have seen it.
		Hamilton disagreed with that view, for he felt that algebra, in some sense, yet not too clearly specified, must somehow be used to describe the sequences of actions and patterns of events as found in the real world, and the algebraic operations should therefore have their parallels in the physical world of known phenomena.
		Acting in their capacity as mathematicians these academicians altered the symbol, their exact motivation is still unclear, but it seems that the vertical wedge may have been easier to write, and some element of fashion may have played a role.

		Thus the rule is the unit of the Quaternion system, while the square reminds us that the right angle is the unit versor." With this aptitude for interpreting the symbolic, displayed here in his speculations on masonic tools, it becomes even harder to understand how he could have missed the implications of Hamilton's symbol.
		Only the nabla acting to the right appears in the public written scientific literature, and if Tait is seeking a new sensation, he would do well to think along the lines of the other ways things can be arranged.
		McAulay was on the right track, but missed the simple "major forms" of the differential operator that Maxwell alluded to in his cryptic letter to Tait, and instead had constructed a differential notation that was in some sense too general once again.
