His family was rather modest, but thanks to the generosity of his uncle Arthur Biddell, he went to study at Trinity College , University of Cambridge.

Although a sizar, 1 he was a brilliant student and finally graduated in as a senior wrangler. Three years later he was appointed to the celebrated Lucasian chair of mathematics. In , Airy obtained the Plumian chair, becoming professor of Astronomy and direc to r of the new observa to ry at Cambridge. His early work at this time concerned the mass of Jupiter and the irregular motions of the Earth and Venus.

In , Airy started his first mathematical studies on the diffraction phenomenon and optics. Due to diffraction, the image of a point through a telescope is actually a spot surrounded by rings of smaller intensity. This spot is now called the Airy spot; the associated Airy function, however, has nothing to do with the purpose of this book.

Under his administration, modern equipment was installed, leading the observa to ry to worldwide fame assisted by the quality of its published data. The question of absolute time was also a major challenge: Airy defined the Airy Transit Circle, which in became the Greenwich Mean Time. However the renown of Airy is also due to the Neptune affair.

During the decade — 1 Meaning that he paid a reduced fee in exchange for working as a servant to richer students. In Engl and , the young John Adams was doing the same calculations with a slight advance. Airy however was dubious about the outcome of his work. Adams tried twice to meet Airy in but was unsuccessful: the first time Airy was away, the second time Airy was having dinner and did not wish to be disturbed.

Finally, Airy entrusted the astronomer James Challis with the observation of the new planet from the calculations of Adams. Unfortunately, Challis failed in his task. At the same time, Le Verrier asked the German astronomer Johann Galle in Berlin to locate the planet from his data: the new planet was discovered on 20 September A controversy then started between Airy and Arago, between France and Engl and , and also against Airy himself. The dispute became more acrimonious concerning the name of the planet itself, Airy wanting to name the new planet Oceanus.

The name Neptune was finally given. In Airy attempted to determine the mean density of the Earth by comparing the gravity forces on a single pendulum at the to p and the bot to m of a pit. The experiment was carried out near South Shields in a mine feet in depth.

Taking in to account the elliptical form and the rotation of the Earth, Airy deduced a density of 6. The results were published in , but in he found an error in his calculations. The author was then 89 years old and was unwilling to revise his calculations. Late in , Sir George retired from his position as astronomer at Greenwich.

He died January 2, The au to biography of Sir George, edited by his son Wilfred, was published in [W. The name of Airy is associated with many phenomena such as the Airy spiral an optical phenomenon visible in quartz crystals , the Airy spot in diffraction phenomena or the Airy stress function which he introduced in his work on elasticity, which is different again from the Airy functions that we shall discuss in this book.

Among the most wellknown books he wrote, we may mention Mathematical tracts on physical astronomy and Popular astronomy [W. Airy was particularly involved in optics: for instance, he made special glasses to correct his own astigmatism.

For the same reason, he was also interested in the calculation of light intensity in the neighbourhood of a caustic [ Airy , ]. This is the object of the present book. The problem is that this series is slowly convergent as m increases. A few 4 Airy Functions and Applications to Physics years later, S to kes , introduced the asymp to tic series of W m , of its derivative and of the zeros.

Practically no research was undertaken on the Airy function until the work by Nicholson , Brillouin and Kramers who contributed significantly to our knowledge of this function.

Then with a change of variable, we find the Airy equation. This method is particularly useful in the neighbourhood of a zero of F x. Short-link Link Embed. Share from cover. Share from page:.

Airy functions are applied in many branches of both classical and quantum physics. Airy on the intensity of light in the neighborhood of a caustic Airy , Details of the Airy theory are given in van de Hulst in the chapter on the optics of a raindrop. See also Berry , The frequent appearances of the Airy functions in both classical and quantum physics is associated with wave equations with turning points, for which asymptotic WKBJ solutions are exponential on one side and oscillatory on the other. The Airy functions constitute uniform approximations whose region of validity includes the turning point and its neighborhood. Within classical physics, they appear prominently in physical optics, electromagnetism, radiative transfer, fluid mechanics, and nonlinear wave propagation.

In the physical sciences, the Airy function or Airy function of the first kind Ai x is a special function named after the British astronomer George Biddell Airy — The function Ai x and the related function Bi x , are linearly independent solutions to the differential equation. This is the simplest second-order linear differential equation with a turning point a point where the character of the solutions changes from oscillatory to exponential.

Skip to search form Skip to main content You are currently offline. Some features of the site may not work correctly. The Airy function Ai z and its derivative Ai' z occur in a large number of applications in Chemistry and Physics. As a result, there is a continuing interest in the properties of these functions. Recently, there has been interest in obtaining general expressions for the higher derivatives of these functions. In this work, general expressions for the polynomials which are contained in these derivatives are given in terms of the partial Bell polynomials. View PDF on arXiv.

The use of special functions, and in particular of Airy functions, is rather common in physics. The reason may be found in the need, and even in the necessity, to express a physical phenomenon in terms of an effective and comprehensive analytical form for the whole scientific community. However, for almost the last twenty years, many physical problems have been resolved by computers. This trend is now becoming the norm as the importance of computers continues to grow. As a last resort, the special functions employed in physics will have, indeed, to be calculated numerically, even if the analytic formulation of physics is of first importance. The knowledge on Airy functions was periodically the subject of many review articles.

Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. It only takes a minute to sign up. However, it is obviously quite different from the special functions Ai x that usually go by that name. This function resembles probability density function of the wrapped Cauchy distribution. I've heard that Fabry and Perot gave it this name in one of their original papers maybe this one? It would be great if someone could help ferret out the first reference to that function by this name. I have noticed this in the literature as well.

In the physical sciences, the Airy function or Airy function of the first kind Ai x is a special function named after the British astronomer George Biddell Airy — The function Ai x and the related function Bi x , are linearly independent solutions to the differential equation. This is the simplest second-order linear differential equation with a turning point a point where the character of the solutions changes from oscillatory to exponential. For the same reason, it also serves to provide uniform semiclassical approximations near a turning point in the WKB approximation , when the potential may be locally approximated by a linear function of position. The triangular potential well solution is directly relevant for the understanding of electrons trapped in semiconductor heterojunctions.
