Nicolas Roeg was unlike anyone else, and a genius at what he did. A lot of directors leave you to your own devices, but when we worked together on The Witches, Nic–who died at 90 on Nov. 23–knew exactly what he wanted. It hadn’t occurred to me that a witch in a children’s movie should be sexy. Nic’s attitude was “Whyever not?” An adult who could dream like a child, he had no tolerance for propriety and dull stuff like that. And I always remember his encouragement.

AbstractTheoretical models for the coefficient of thermal expansion (CTE) first proposed in the 1970s are expanded upon, allowing them, for the first time, to be implemented over a wide temperature range. The models are of interest because they predict the effects of the changes in the crystal lattice spacing and crystallite modulus on the CTE. Hence, they can in turn be used to investigate the influence of pressure and irradiation on the CTE.
