Rise and Fall of the Carbon Civilisationscover other forms of life outside the Earth. It is interesting that astrobiology looks in particular at life on Earth in the most extreme conditions like at some depth in the crust or in the deepest of the oceans. Astrobiology has received official attention from all space agencies like ESA or NASA

Rise and Fall of the Carbon Civilisationh. In that geobiology is parallel to the use of physics and chemistry methods that transformed geology in geophysics and geochemistry. The origin of geobiology can be traced to the 1970s when the Gaia hypothesis was formulated.

Engineering for Greater Energy Efficiency,ard deviation from the mean. Beside the mean must be carried out over some time interval and this is a crucial point. As a matter of fact, climate changes with time so that the interval must be long enough but not too long that would eliminate long term variations. In statistical mechanics such a pr
