22.09.08 2 Workshop in Esbjerg Introduction 3000 km 4000 km Unfulfilled need in chemometric education in Russia Low number of qualified specialists in chemometrics Large distances, e.g. Moscow – Barnaul is about 3000 km No modern chemometrics books in Russian No available chemometric software No support from officials: government, Academy, etc Barnaul Easy available everywhere => INTERNET Interactive layout: all calculations should be clear and repeatable Web friendly environment for the calculations => EXCEL Necessity to make and use our own (free) software => EXCEL Add-In
