In the history of human contact with nature two periods can be distinguished: the first period is subordination of human economic activity to nature’s rhythm, full of fear of the physical world. The second is the Industrial Age, featuring increased economic activity divorced from natural cycles, the desire to discover the principles that govern nature. Technological development produced a feeling of safety and independence from the outside world, bringing on the cult of man’s greatness. This was connected with a number of myths: „Nature is nothing sacred”, „One may intervene in everything”, „All problems are solvable”. There is also the myth of abundance: „There is plenty of everything”. This has resulted in the modern contempt for nature. Another myth is that „There is too little of everything”. This leads to a desire to possess more than other people do. The author ponders how this is reflected in social life.
Interactions between anomers of D-fructose and D-glucose, D-fructose and sucrose as well as D-glucose and sucrose in so-called computer vacuum and in aqueous solutions were recognized by means of the MM+ calculations. The strongest interactions were observed in the combinations of two ß-glucopyra- noses, α-glyucopyranose with α-fructopyranose and sucrose with ß-glucopyranose. Rheoiogical studies of aqueous solutions of the saccharide blends showed negligible differences in the viscosity for all tested combinations. The system of a lower calculated energy had a higher experimental viscosity.

Structure of aqueous D-fructose solutions

100%
Unusually low viscosity of aqueous solutions of D-fructose was attempted to be explain. The AMl-calculations were carried out for all isomer-conformers of D-fructose under vacuum and in aqueous solutions. Under vacuum, 2 α-D-Frup molecules formed the most stable pair, whereas in the aqueous solution the energetical preferences were found for the β-D-Frup-ß-D-Fruf pair. The differences in the energy for particular hydrated D-fructose isomer-conformer pairs, were within the order of energy available from the intermolecular collisions. Therefore, one could suggest that there would be practically a little chance for controlling rheology of aqueous D-fructose solutions. The energetical characteristics of the structures of D-fructose hydrates is given.
How to explain that contrary to ads jogging on the smoky streets is not „a run for health” but „a run for desease”. On one hand, the economic system promotes „being someone” as being an owner, that is emphasizing satisfying material needs; on the other hand, it shows new ways to strengthen this consumerist's attitude. Thus, human needs are being restricted to the world of material values. Such perception of human needs limited to a single dimension only contradicts the man's inherent development. The quantitative dimension must nevertheless be accompanied by the qualitative one. This covers not only spiritual needs but also the need of proper biological existence determined by the quality of the environment.
