Mathematics is much more than a language for dealing with the physical world. It is a source of models and abstractions which will enable us to obtain amazing new insights into the way in which nature operates. Indeed, the beauty and elegance of the physical laws themselves are only apparent when expressed in the appropriate mathematical framework.
If instead policy makers and program managers participate in an interdisciplinary assessment team, make informal visits to local families and have in-depth conversations with local providers and health authorities, the real needs and complex challenges of organizing good reproductive health services become apparent. The first country that implemented this participatory program of assessment, research and policy development was Brazil. I was one of the outsiders who provided support to the initiative.
If a country develops an economic system that is based on how to pay for the war, and if the amounts of fixed capital investment that are apparent are tied up in armaments, and if that country is a major exporter of arms, and its industrial fabric is dependent on them, then it would be in that country's interests to ensure that it always had a market. It is not an exaggeration to say that it is clearly in the interests of the world's leading arms exporters to make sure that there is always a war going on somewhere.
Finally, to the theme of the respiratory chain, it is especially noteworthy that David Kellin's chemically simple view of the respiratory chain appears now to have been right all along-and he deserves great credit for having been so reluctant to become involved when the energy-rich chemical intermediates began to be so fashionable. This reminds me of the aphorism: 'The obscure we see eventually, the completely apparent takes longer'.
