What Is Life? The Physical Aspect of the Living Cell is a 1944 science book written for the lay reader by the physicist Erwin Schrödinger.The book was based on a course of public lectures delivered by Schrödinger in February 1943, under the auspices of the Dublin Institute for Advanced Studies, where he was Director of Theoretical Physics, at Trinity College, Dublin.
Definition of life. A part of Trifonov's work on the molecular evolution is his aim to find a concise definition of life. He collected [30] 123 definitions by other authors. Instead of dealing with logical or philosophical arguments, he analyzed the vocabulary of the present definitions.
Biologists are able to study life at multiple levels of organization, [1] from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations. [1] [6] Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use.

Earth science generally recognizes four spheres, the lithosphere, the hydrosphere, the atmosphere and the biosphere [3] as correspondent to rocks, water, air and life respectively. Some scientists include as part of the spheres of the Earth, the cryosphere (corresponding to ice ) as a distinct portion of the hydrosphere, as well as the ...
Some scientists have proposed in the last few decades that a general theory of living systems is required to explain the nature of life. [1] Such a general theory would arise out of the ecological and biological sciences and attempt to map general principles for how all living systems work.
Beauty in nature has historically been a prevalent theme in art and books, filling large sections of libraries and bookstores. That nature has been depicted and celebrated by so much art, photography, poetry, and other literature shows the strength with which many people associate nature and beauty.
