Bakerian Lectures dealing with astronomical topics have occurred roughly every ten years during this century. They have therefore something of the character of reports on progress and one need read no further back than Hoyle’s ‘Review of recent d

Harrie Stewart Wilson Massey suffered a long painful illness with great fortitude. Two months before he died he phoned me (D. R. B.) to ask me if I would be responsible for this Memoir. I visited him in his home on 27 September. Telling me he had sca

As a preliminary to the British series of rocket-grenade experiments for determining upper atmosphere temperatures and winds, a number of tenth-scale tests using anti-aircraft shells to simulate grenades were carried out at Shoeburyness in 1956. The

A criterion that must be satisfied by the positive-ion energy distribution at the edge of a sheath surrounding a negative probe is derived for the case when negative ions are present. This criterion is then used to derive the potential outside the sh

The satellite Ariel I, launched in April 1962, provided a survey of the topside ionosphere over a latitude range of ± 55°. The measurements made by the ion energy spectrometer showed the ions O + and He + to be the major massive components of the i

Previous investigations of the ionospheric plasma by means of probes (see, for example, the review by Bourdeau (1963) have generally been based on the method used by Langmuir in his classic studies of the gas discharge (Mott-Smith & Langmuir 1926). A

An account is presented of the first grenade experiments carried out at the Woomera rocket range during 1957-59. A description is given of the grenades and their rocket installation; and of the optical and acoustical instrumentation required to deter

After the capture of a number of German V 2’ s in 1946 the study of the solar spectrum beyond 2900 Å first became possible. The V 2 was a ballistic rocket with a range of 180 miles, and when used as a research instrument was capable of carrying a

The main observational needs of X-ray astronomy are briefly reviewed and the existing techniques with their limitations are discussed. Some promising new developments are introduced and the properties of some important systems in terms of signal/nois

This paper is the second in a series of studies of low-pressure discharges in which an electronic method was used for the Druyvesteyn analysis of electron energy distribution. The method reported in the first paper (Boyd & Twiddy 1959) has been appli
