Eratosthenes was one of the great scholars of Antiquity. Born in Cyrene in c. 285, he studied in Athens before becoming the third librarian at the great research institute founded by King Ptolemy I at Alexandria in Egypt. Rather than specializing in any one field, he produced scholarship in philology, geography, mathematics, philosophy, and chronography, as well as composed poetry. This breadth of learning was (remarkably) the subject of criticism: he was called “Beta” and the “Pentathlete,” which referred to being the second-best in every field. But his versatility did not preclude considerable achievement: most notably, he calculated the circumference of the earth and made other great intellectual advances in geography (where his influence on the later geographer Strabo was considerable) and literary criticism (where, for instance, he refused to believe that the places of Homer’s Odyssey could be mapped onto the actual Mediterranean world), as well as receiving praise for his poetry (from pseudo-Longinus). His works have not survived in full; the process of gathering and assessing his fragments is still ongoing.

Kenneth Lyon Blaxter (KB as most people called him) was born and brought up in the region of Norwich. He graduated in agriculture in the University of Reading in 1939. In 1948 he was appointed head of the Nutrition Department of the Hannah Dairy Research Institute, and in 1965 Director of the Rowett Research Institute, Aberdeen. He retired in 1982, but remained extremely active in writing and in work on a number of committees until his premature death from a tumour of the brain in 1991. KB was probably the leading world authority on the nutrition and food requirements of farm animals. A man of many parts, with a remarkable breadth of knowledge and range of interests, he was one of those increasingly rare people who, starting with no scientific education, achieved great distinction in his field. The thread which bound his whole life together was a fascinated reverence for all forms of life on earth. It began in boyhood, with the collection of grasses and bugs, expanded to animals and eventually to a politically conscious concern for the earth and mankind. Shortly before he died Kenneth composed an autobiographical memoir for his family. [Verbatim quotations are set in small, indented type.]

The Mean

The motion of an artificial satellite around the Moon is much more complicated than that around the Earth, since the shape of the Moon is a triaxial ellipsoid and the effect of the Earth on the motion is very important even for a very close satellite.The differential equations of motion of the satellite are written in canonical form of three degrees of freedom with time depending Hamiltonian. By eliminating short-periodic terms depending on the mean longitude of the satellite and by assuming that the Earth is moving on the lunar equator, however, the equations are reduced to those of two degrees of freedom with an energy integral.Since the mean motion of the Earth around the Moon is more rapid than the secular motion of the argument of pericentre of the satellite by a factor of one order, the terms depending on the longitude of the Earth can be eliminated, and the degree of freedom is reduced to one.Then the motion can be discussed by drawing equi-energy curves in two-dimensional space. According to these figures satellites with high inclination have large possibilities of falling down to the lunar surface even if the initial eccentricities are very small.The principal properties of the motion are not changed even if plausible values ofJ3andJ4of the Moon are included.This paper has been published in Publ. astr. Soc.Japan15, 301, 1963.

The Impact

The phenomena accompanying the impact of large meteorites on the surface of the Moon or of the Earth can be examined on the basis of the theory of explosive phenomena if we assume that, instead of an exploding meteorite moving inside the rock, we have an explosive charge (equivalent in energy), situated at a certain distance under the surface.

Origin Of The Moon

The difference between average densities of the Moon and Earth was interpreted in the preceding report by Professor H. Urey as indicating a difference in their chemical composition. Therefore, Urey assumes the Moon's formation to have taken place far away from the Earth, under conditions differing substantially from the conditions of Earth's formation. In such a case, the Earth should have captured the Moon. As is admitted by Professor Urey himself, such a capture is a very improbable event. In addition, an assumption that the “lunar” dimensions were representative of protoplanetary bodies in the entire solar system encounters great difficulties.

Origin Of The Moon

During the last 10 years, the writer has presented evidence indicating that the Moon was captured by the Earth and that the large collisions with its surface occurred within a surprisingly short period of time. These observations have been a continuous preoccupation during the past years and some explanation that seemed physically possible and reasonably probable has been sought.
