Brillhart discovered in 1965 that the continued fraction of the real root of the cubic equation x3—8x—10 = 0 has a number of very large partial quotients. In this paper we explain why this phenomenon is surprising and then show how its consideration naturally leads one into some very deep branches of the theory of numbers before the reason for the phenomenon becomes clear. In order to make the paper intelligible to non-specialists we give a brief account of the classical theories of continued…

Some computational aspects of, and the use of computers in, algebraic number theory
An explanation is given of how the application of a computer has contributed to the progress of research in this area and several number-theoretic questions are expounded for which the use of acomputer seems to be appropriate but has not extensively been made.
On the method of Thue-Siegel
The methods of Thue and Siegel, based on explicit Pade approximations to algebraic functions, are used to examine diophantine approximations to roots of
