ROSENHAIN CENTENARY CONFERENCE A Joint Symposium of The Metals Society, The National Physical Laboratory, and The Royal Society held on 22-24 September 1975

The Proceedings of an international conference held in London, 22-24 September 1975 to pay honour to the memory of Walter Rosenhain, F.R.S., one of the great metallurgists of this century. Practising engineers and metallurgists discussed in detail the application of physical metallurgy to the design and functioning of bridges, pipelines, offshore structures, airframes, aero engines and undercarriages. The conference was uniquely successful in showing the relation between the control of metallurgical structure and its influence on engineering design. Copious examples are given and many guidelines produced for the future. The development of physical metallurgy as a university discipline was discussed against this background. The meeting took the form of six sessions, each consisting of a number of papers under the following headings:

1. ENGINEERING REQUIREMENTS

2. design Implications for materials selection

3. MATERIALS DEVELOPMENT PRESENT AND FUTURE

4. THE FUTURE ROLE OF PHYSICAL METALLURGY IN RELATION TO ENGINEERING PRACTICE

5. THE TASK FOR THE EDUCATOR

The Royal Society, 6 Carlton House Terrace, London SW1Y 5AG QUANTITIES, UNITS, AND SYMBOLS Second edition 1975 When the 1971 edition of this handbook was issued it was boldly suggested that it was likely to be of interestto all whose business it wasto 'order all things by measure, by number, and by weight'. The rapid disposal of that edition and the encourage­ ment of much informed comment gives confidence that it is justifiable to repeat the remark on the occasion of the publication of a new edition. The general arrangement of the handbook is substantially unchanged; the sections appear in the same sequence as previously, but they are now presented in a clearer style to facilitate easier reference. With the incorporation of additions and altera­ tions resulting from recent decisions of the relevant international bodies the hand­ book has been updated to the end of 1974. The adoption of helpful suggestions by members of the Royal Society Symbols Committee and others has resulted in further improvements, in particular the addition of a new section entitled 'Sources' which gives concisely the authority for statements made throughout the handbook. In consequence the new edition of Quantities, units, and symbols can be confidently recommended to all members of the scientific community. The contents include: Physical quantities and symbols for physical quantities Units and symbols for units Numbers Recommended mathematical symbols Chemical elements, nuclides, and particles Quantum states Nuclear physics Thermodynamic results Galvanic cells Some common abbreviations Recommended values of physical constants Sources Bibliography
