Anaximander posited that every element had an opposite, or was connected to an opposite (water is cold, fire is hot). Thus, the material world was said to be composed of an infinite, boundless apeiron from which arose the elements (earth, air, fire, water) and pairs of opposites (hot/cold, wet/dry). There was, according to Anaximander, a ...
life preserver a type of weapon for self-defence (US: blackjack) life vest, personal flotation device (UK: lifebelt or lifejacket) lift (n.) platform or cage moved vertically in a shaft to transport people and goods to various floors in a building (US: elevator) ride as a passenger in a vehicle (as in, to give someone a lift)
Pure water containing no exogenous ions is an excellent electronic insulator, but not even "deionized" water is completely free of ions. Water undergoes autoionization in the liquid state when two water molecules form one hydroxide anion (OH −) and one hydronium cation (H 3 O +). Because of autoionization, at ambient temperatures pure liquid ...
Water for bathing may be maintained in satisfactory microbiological condition using chemical disinfectants such as chlorine or ozone or by the use of ultraviolet light. Water reclamation is the process of converting wastewater (most commonly sewage, also called municipal wastewater) into water that can be reused for other purposes.
In other words: The smaller the diffracting object, the 'wider' the resulting diffraction pattern, and vice versa. (More precisely, this is true of the sines of the angles.) The diffraction angles are invariant under scaling; that is, they depend only on the ratio of the wavelength to the size of the diffracting object.
Other examples are diwa (idea, concept or spirit) and diwata (nature spirit, demi-goddess) which have related meanings to the original Sanskrit words of deva (divine) and devata (deity). [ 19 ] “So there is a possibility that the oral tradition of saying “bahala na” may have directly originated from the Sanskrit/Hindi word of "bharaNa" in ...
an ecocline is a variation of the physicochemical environment dependent of one or two physico-chemical factors of life, and thus presence/absence of certain species. [9] An ecocline can be a thermocline , chemocline (chemical gradient), halocline (salinity gradient) or pycnocline (variations in density of water induced by temperature or salinity).
In other words, light appeared to be dragged by the water, but the magnitude of the dragging was much lower than expected. The Fizeau experiment forced physicists to accept the empirical validity of an Fresnel's model, that a medium moving through the stationary aether drags light propagating through it with only a fraction of the medium's ...
