The human body can be described as a machine controlled by the world's most sophisticated microcomputer, about the size of a grapefruit and largely self-programmable. The machine is self-propelled in any direction with a forward speed of up to 30 kilometres per hour or so but capable of only transient vertical travel to a maximum height of about 2.5 metres. It is largely waterproof, entirely rustproof and partially immersible. Its control is effected, with automatic feedback, through self-adjusting binoculars and by auditory, olfactory, tactile (from sound, smell and touch!) and taste signals.
The machine is equipped with a pair of sophisticated remote manipulators. It is powered by a wide variety of fuels (ideally unleaded) via a multipurpose carburettor that is partly self-regulating. The machine can self-replicate (with assistance from a similar machine), producing a hybrid model. Although no guarantee is provided, a new machine has an expected lifespan of about 70 years.
To a large extent, the machine is self-repairing. However, in the event of a malfunction, diagnosis of the problem (and its correction) should be achieved ideally without lifting the bonnet and with minimal damage to external bodywork or internal components. However, no manuals are provided relating to construction, function, operation or repair. Instead, there is a need to rely on science in general and particularly on Physical and Engineering Sciences.
The International Union for Physical and Engineering Sciences in Medicine (IUPESM) comprises a global network of 60,000 graduate Medical Physicists and Biomedical Engineers in about 100 countries. These dedicated professionals are working to improve health and well-being of people throughout the world, particularly in Developing and Emerging Countries. All members of IUPESM have specialised postgraduate training, many with higher degrees, and there are increasingly national statutory requirements for registration to practice. Their activities include research and development that exploits Physical and Engineering Sciences for the maximum benefit of patients and people with disabilities. Scientific support is provided for clinical colleagues in a wide variety of diagnostic and therapeutic procedures and, in some cases, services are provided directly to patients and the disabled.
IUPESM is committed to improving public understanding of the applications of science and engineering in health care. This brochure, produced with support from the International Council for Science (ICSU) of which IUPESM is a member, is intended to describe in readily understandable language some aspects of the 'Scientific Wonderland', caring for the 'Human Machine'.
We are greatly indebted to Professor Brian Diffey for his primary role in producing the brochure and to members of IUPESM, particularly Professors Dov Jaron, Al Wald and Colin Orton, for their editorial contributions. We hope that you will find its contents of interest.
