Topic: 1552 Bessel

	Friedrich Bessel - Wikipedia, the free encyclopedia
		Bessel was a contemporary of Carl Gauss, also a mathematician and astronomer.
		Bessel was the son of a civil servant, and at the age of 14 he was apprenticed to the import-export concern Kulenkamp.
		In 1838 Bessel won the "race", announcing that 61 Cygni had a parallax of 0.314 arcseconds; which, given the diameter of the Earth's orbit, indicated that the star was ~3 parsecs away.

	Friedrich Wilhelm Bessel (1784-1846)
		Bessel's first contribution to astronomy had been on comet Halley's 1607 aparation, and he always stayed interested in comets, both by observing and by calculating their orbits; for this purpose, he improved the orbit calculation methods.
		Bessel was the first to measure and publish a parallax, and calculate the distance to a star, double star 61 Cygni, from observations during 18 months in 1837 and 1838.
		Bessel's parallax value of 0.314", corresponding to a distance of 3.18 parsec or 10.4 light years, is very close to the modern value of 0.292", corresponding to 3.42 pc (11.2 ly).

		Friedrich Bessel - Scientists - German Archive: Friedrich Wilhelm Bessel (July 22, 1784 — March 17, 1846) was a German mathematician, astronomer, and systematizer of the Bessel functions (which, despite their name, were discovered by Daniel Bernoulli).
		In 1838 Bessel won the 'race', announcing that 61 Cygni had a parallax of 0.314 arcseconds; which, given the diameter of the Earth's orbit, indicated that the star was ~3 parsecs away.
		His announcement of Sirius' 'dark companion' in 1841 was the first correct claim of a previously unobserved companion by positional measurement, and eventually led to the discovery of Sirius B. Despite lacking a university education, Bessel was a major figure in astronomy during his lifetime.

		In 1552 Jorgen was given the command of Vordingborg Castle, which was a promotion to a more important role.
		We know today that it is the second of these which is true, and that the scale is such that Tycho would have had no hope in measuring parallax with his instruments.
		The first measurement of the parallax of a star was in 1838 by Bessel who found 0.3" for the parallax of 61 Cygni.

		The book discusses operations with Arabic numerals, computation with counters, proportion, the 'rule of three', all arithmetic being studied for the natural numbers in the first version which had second and third editons in 1549 and 1550.
		In 1552 Recorde published a second enlarged version of The Grounde of Artes extending the work of the first edition to rational as well as whole numbers and including such topics as 'false position'.
		He wrote a number of important books: Topics from the theory of numbers (1966), Bessel polynomials (1978), Dedekind sums (written jointly with Hans Rademacher) (1972), and Representations of integers as sums of squares (1985).

		If I go back up through Aschbacher-Bruck-Brauer-Schur-Frobenius to Ernst Kummer, I have that Ernst Edward Kummer's advisor was Heinrich Fredinand Scherk whose advisors were Friedrich Bessel [22 July 1784-17 Mar 1846] and Heinrich Brandes.
		Friedrich Wilhelm Bessel's advisor was Carl Friedrich Gauss [already on our list].
		Bessel was not just a Mathematician, but also an eminent Astronomer.

		Our \ goal in this tutorial is to study the solution properties of Bessel's \ equation and to illustrate how Bessel's equation arises in the solution of \ heat conduction problems.
		Before we begin it is important to note that \ Bessel's equation can also be expressed as\n\n\t\t", Cell[BoxData[ \(\(r\^2\) \(\(d\^2\) y\)\/dr\^2 + r\ dy\/dr + \((\(\[Lambda]\^2\) r\^2 - \[Nu]\^2)\) y = 0\)]], "\n\t\t\nThis form arises from a simple change of variables ", Cell[BoxData[ \(t = \[Lambda]\ r\)]], ".
		To show the steps leading to the above form we use the chain rule of \ differentiation.
