Opis

The living organisms and systems possess extraordinary properties of programmed development, differentiation, growth, response, movement, duplication of key molecules and in m any cases higher mental functions. But the organisms are physical objects so they must follow laws of physics yet they do not seem to obey them. Physicists cannot easily persuade themselves to accept this as finally true. Non-living objects are governed by these laws of physics and they can explain these properties. However, in the living systems too phenomena encountered like coupled non-linear interactions, manybody effects, cooperativity, coherence, phase transitions, reversible metastable states are being understood better with the aid of powerful theoretical and experimental techniques and hope is raised that these may let us understand the mysteriousness of life. Contributors to this volume are a small fraction of rapidly growing scientific opinion that these aspects of living bodies are to be expected in a hitherto inadequately suspected state of matter which is in the main directed by these physical properties pushed almost to limit. This state of matter, the living matter, deserves to be called The Living State. Mishra proposes that given hydrogenic orbitals, atoms showing easy hybridisability and multiple valances, molecules with low-lying electronic levels, "loosestructure", and a metabolic pump in thermodynamically open system, various fundamental properties of living state can emerge automatically. Structurally these are all known to be present.
