The World

This paper looks at optometry museums around the world. There are only five general optometry museums: three are hosted by optometric institutions in three countries, Australia, Britain and the U.S.A., one is hosted by a Canadian university that has an optometry school, and one is in private hands in Southbridge, Massachusetts. They are supplemented by six excellent corporate museums in France, Germany and Italy, but these museums focus on either spectacles or ophthalmic instruments, rather than optometry in general. Two of the optometry museums were founded over 100 years ago, and two have had their 50th birthday, but can they survive forever? Museums are expected to preserve collections for posterity for the edification and enjoyment of future generations, yet all institutions are at risk of disruption: few institutions last more than a couple of hundred years. This paper discusses strategies optometry museums might pursue to guard against mismanagement and neglect and provide for the protection of their collections in the event of the demise of the museum or its host institution.

AbstractThe observations of α Vir with the Narrabri Stellar Intensity Interferometer demonstrated the potential of long baseline interferometry for the determination of fundamental properties of double-lined spectroscopic binary systems. Since the completion of the programme with the Narrabri instrument the Chatterton Astronomy Department has been conducting a study aimed at developing a stellar interferometer with limiting magnitude V ≳ +8 and maximum baseline ≳ 1 km (resolution at 500 nm ≲ 7 × 10−5 seconds of arc). The way in which a long baseline interferometer may be used in the study of binary stars is outlined, the requirements for this work are discussed, and the current status and future plans of the Chatterton Astronomy Department’s programme to develop a new long baseline interferometer are summarised.

Definitive Form

Oliver Knussen's Symphony in One Movement is his latest symphony. It is also his earliest – originally composed as the Concerto for Orchestra in 1969, and premièred by the 17-year old Knussen and the London Symphony Orchestra, with André Previn playing the flamboyant piano part. 33 years later, the piece has finally reached its definitive form, and Knussen conducted the BBC Symphony Orchestra in its world première as part of an all-Knussen programme in celebration of his 50th birthday, at the Barbican Hall on 1 November.
