ProfessorToyoichi TanakaofMIThasdevelopedgelscienceafterthediscoveryofvolumephasetransition,but unfortunately he passed away so early in 2000. His friends and co-workers decided to organizeasymposiumcommemoratingthe30thanniversaryforthediscoveryofthevolume phasetransitionin1978. ThesymposiumwasheldinastyleofFaradayDiscussions. FullpaperswritteninJapanese weresentbeforehandtoalltheparticipants,anddiscussionswereactiveafterashort(5min) presentationofeachpaper. SinceJapaneselanguageisverydifferentfromEuropeanl- guages,weJapanesecouldspeakfreelywithoutanyhesitation. Althoughalltheparticipants are good at English as proved by their publication of many papers in English, yet the discussionofdelicatenuancescouldbedonebetterinJapanesethaninEnglish. Afterthesuccessfulsymposium,paperswritteninEnglishtakingintoaccountthedisc- sionsduringthesymposiumwerereviewedbyexpertscientists,andthepaperswererevised accordingly. We hope that this collection of papers is interesting and useful for all the scientistsandengineersworkingintheareaofgelsbothinacademiaandindustry. Finally, wethankallthecontributorsandreviewersfortheirenthusiasticefforts.
