Chlorine is sometimes proposed as a biological alternative to oxygen, either in carbon-based biologies or hypothetical non-carbon-based ones. Chlorine is much less abundant than oxygen in the universe, however, and so it is unlikely that a planet will be able to form which has a large enough concentration of chlorine available on its surface to form the basis of a biochemistry. Chlorine will instead likely be bound up in the form of salts and other inert compounds. Sulfur is also able to form long-chain molecules, but suffers from the ...

Helium - Gas and plasma phases. Helium is a colorless, odorless, and non-toxic gas. It is the least reactive member of group 18 (the noble gases) of the periodic table and therefore virtually inert. Under standard temperature and pressure helium behaves very much like an ideal gas. Under virtually all conditions helium is monatomic. It has a thermal conductivity that is greater than any gas except hydrogen and its specific heat is unusually high. Helium is also less water soluble than any other gas known and its ...

In the case of a closed volume, it is easy to compute the amount of water. Indeed, when the volume is tight, the air can not come in; and the air is necessary for the combustion, the oxygen O2 (pure air contains 21% of O2). Whatever the amount of fuel available (wood, paper, cloth), the combustion will stop when the air becomes "thin", i.e. when there is less than 15% oxygen. This gives: the amount of water required to make the atmosphere inert, i.e. to prevent the pyrolysis gases to burn; this is the "vol ...

Seker, Seket (Egyptian) One of the aspects of Ptah, also the name of Osiris in Memphis, especially in his character of Lord of the Underworld -- Ptah-Seker-Asar, the triadic god of the resurrection. Ptah-Seker is the personification of the union of the primeval creative power with a form of the inert power of darkness, or a cosmic rendering of the very mystical thoughts around the term the "night sun."

The Seker-boat (Hennu), representing the second half of the daily journey of the sun through the Underworld, is so named because Ra the Aged is said to be like Horus, while Ra the Younger is said to resemble Seker.

Noumenon [from Greek noeo to perceive with the mind, think; cf nous]

Plural Noumena. An object perceived by the mind apart from the senses, an object of cognition. Also the unknown real entity, substance, or essential thing-in-itself, which the mind perforce posits as the basis of the phenomenon, appearance, or objective thing; hence reality as distinguished from apparent or sensible qualities.

Thus aether or akasa is called the noumenon of ether; noumena are the conscious guiding causes behind the physical cosmic forces and elements. The emphasis is upon consciousness and intelligence as opposed to mere appearances, or to the conception of the blind forces and inert elements of materialism. Behind every phenomenon must lie a noumenon: the former is the intelligent cause, the latter the produced effect or appearance.

Vitalism The theory that the phenomena of organic life cannot be explained by the properties of physical matter alone, and that consequently they must be due to some nonphysical vital principle. Attempts to define such a principle have been vague and various. If it is spirit, then what can spirit be, apart from matter, or how can it act on matter? Perhaps it is another kind of matter -- an aether, fluid, or what not.

The theory amounts to trying to correct one error by means of another. If we suppose the physical universe to be composed of inert particles, how can we explain their activity? Materialistic science has simply shelved the difficulty. It is necessary to postulate an immaterial force, which in its origin is immaterial and in its manifestations substantial or material, but materialistic science does not recognize anything basically immaterial. It speaks of energy and matter as twin in destructibles, but merely assumes the former without explaining its nature. Moreover the words force and energy are used by science to denote effects occurring in matter. Are these effects without causes?

The difficulty encountered by vitalists, as regards the nature of the vital principle and its power of acting upon matter, is fundamental in the entire materialistic philosophy. The matter and force of materialistic science are highly metaphysical abstractions. No such thing as an inert material particle exists or can exist, for all such inert matter is but life or force in one of its multiform phases of quiescence or equilibrium. Nor can there be an absolutely immaterial force, without relation of function or action in the material worlds. The universe consists of living beings, whose activities may be expressed collectively by the word life. The term matter has been applied to the static aspect of life, and the term force to the dynamic aspect. No distinction valid for this purpose can be drawn between organic and inorganic beings. If there is need of a vital principle for animals and plants, working upon yet other than essential stuff or substance, there is equal need in the case of minerals; but there is no need to postulate such divorce between force and matter in either case.

The jiva or prana of theosophy is not an immaterial spirit different from matter acting on a lifeless body; it is itself substantial, consisting in fact of streams of living beings, life-atoms; and so far from acting on something other than itself called the body, it actually composes the body. The minute analysis to which science is now able to subject physical matter has not succeeded in finding anything more rudimentary than living, moving fire, light, and electricity -- in short, the ocean of jiva.

Sleep

A state of physical inertia with mental relaxation, sleep promotes proper growth of the self. Night is the natural time to sleep and mid-day catnaps should not be more than 15 minutes long except for the very young, very old, very weak and those intoxicated, diseased, exhausted or traumatised. Avoid having a full meal just before retiring to bed. Sleeping on the right side is the most relaxing and good for yoga. On the left, it is most digestive and increases interest in food, sleep and sex. Sleeping on the back indirectly and on the stomach directly encourages disease. Sleeping with crown of the head facing east and feet into the west promotes the best meditative sleep. Washing the hands, feet & face just before improves sleep. Never sleep in the kitchen and go to bed only to sleep. 6 to 8 hours of daily sleep is essential. The ideal form of sleep is yoga – a state of complete physical inertness with retention of mental alertness & awareness.
