No-one who took part in the NATO Advanced Studies Institute from which
this book emerges will have forgotten the experience. True, the
necessary conditions for a very successful workshop were satisfied: a
field of physics bursting with new power and new puzzles, a matchless
team of lecturers, an international gathering of students many of whom
had themselves contributed at the forefront of their subject, an
admirable overlap of experiment and theory, a good mix of experimenters
and theorists, an enviable environment. But who could have foreseen the
way the workshop became a focus for future directions, how fresh
scientific ideas tumbled out of the discussion periods, how the context
of teaching the field produced such fruitfulness of research at the
highest level? The organisers did have some specific aims in mind.
Perhaps foremost was the desire to compare notes among different areas
within the sub field of soft condensed matter physics fast becoming
known as "complex fluids". For readers seeking a definition, the prosaic
"fluids with bits in" can be passed rapidly over in favour of the
elegant discussion of slow variables by Scott Milner in his chapter. The
uniting goals of the subject are to model the essential molecular or
mesoscopic structure theoretically, and to probe this structure as well
as the bulk response of the system experimentally. Our famous examples
were: colloids, polymers, liquid crystals, block co-polymers and
self-assembling surfactant systems.
