	Orders of magnitude (Site not responding. Last check: 2007-10-22)
		More precisely, the order of magnitude of a number can be defined in terms of the logarithm of the number to the base of 10, usually as the integer part of the logarithm.
		The order of magnitude of a number may also be defined as the exponent of the power of 10 when the number is represented using scientific notation.
		For example, an accurate order of magnitude estimate for the human population of the Earth in the year 2000 is 10 billion.

	Orders of magnitude
		An order of magnitude is a factor of ten.
		Orders of magnitude are quite easily and commonly described through the use of scientific notation and powers of ten.
		SI units are used together with SI prefixes: these were devised with orders of magnitude in mind.

		An order of magnitude is the class of scale or magnitude of any amount, where each class contains values of a fixed ratio to the class preceding it.
		Orders of magnitude (time) The geologic timescale is used by geologists and other scientists to describe the timing and relationships between events that have occured during the history of the Earth.
		Thus the order of magnitude of 400 is 2.

		More precisely, the order of magnitude of a number can be defined in terms of the decimal logarithm, usually as the integer part of the logarithm.
		For example, an order of magnitude estimate for a variable between about 3 billion and 30 billion (such as the human population of the Earth) is 10 billion.
		For extremely large numbers, a generalized order of magnitude can be based on their double logarithm or super-logarithm.

	Orders of magnitude/Talk - Wikipedia
		I believe they are often called "orders of magnitude of length".
		What we could do though is to break this list up and put the length part on length, the mass part on mass etc., under a headline of "orders of magnitude of length" or similar.
		Maybe we should do both: put it on length, together with nice examples for every order of magnitude, and keep it here as a general reference table.

	Mass Spectrometry Sample Requirements (Site not responding. Last check: 2007-10-22)
		With a peptide of molecular weight 2000 for which the molecular ion could be measured with picomole amounts, as much as two orders of magnitude more sample could be needed to obtain a good tandem mass spectrum.
		Since the current technology for tandem mass spectrometric sequencing requires peptide fragments of 25-30 amino acids or less, sequencing of a protein requires that it be cleaved into smaller fragments.
		Two orders of magnitude improvement in instrument sensitivity does not necessarily directly translate to two orders of magnitude lower sample requirement, however, since sample manipulation limitations become more significant with extremely small samples.

	More on Mass
		Mass is a property of physical objects that, roughly speaking, measures the amount of matter they contain.
		One of the consequences of the equivalence of inertial mass and passive gravitational mass is the fact, famously demonstrated by Galileo Galilei, that objects with different masses fall at the same rate, assuming factors like air resistance are negligible.
		Classically, active and passive gravitational mass were equivalent as a consequence of Newton's third law, but a new axiom is required in the context of relativity's reformulation of gravity and mechanics.

	Evolution: Library: The Current Mass Extinction
		Is the biosphere today on the verge of anything like the mass extinctions of the geological past?
		Increasingly, researchers are doing the numbers, and saying, yes, if present trends continue, a mass extinction is very likely underway.
		For along with that species richness, the ecosystem is likely to loose much of its ability to provide many of the valuable services that we take for granted, from cleaning and recirculating air and water, to pollinating crops and providing a source for new pharmaceuticals.

	Mass - Energy Conversion in Chemical Reactions
		Then the mass "defect" (as it is called) 4.7 x 10^-12 mol, or multiplying by Avogadro's number = 6.023 x 10 ^23 yields 3 x 10 ^12 atoms or molecules of the substance.
		Although it would be technologically possible to measure the mass defect using high resolution, high precision mass spectrometry, no one really cares except in some very specific areas of nuclear physics.
		However, to be correct in the mass balance, the mass of oxygen reacted should be counted, in which case the mass of reactants = mass of products.

	rest mass
		In special relativity, rest mass is an obsolete term used to describe what is today simply referred to as mass.
		(formerly called "mass", but now called energy) increases with velocity (v), and the rest mass m is the inertial mass at v=0, which corresponds to the classical notion of mass.
		The terms rest mass and relativistic mass can be still be found in elementary textbooks and popularisations of relativity, but their use is depreciated in graduate-level physics.

		Orders of magnitude reduction in costs are possible when compared to all processes requiring electrolysis for the production of rocket fuels or propellants and to all electric propulsion systems.
		Estimates suggest 20 to 100 tons of mass for this architecture, launched from earth, would be able to return 14,000 tons per year, and 140,000 tons of mass to LEO during the operational lifetime (reference 3,4).
		The origin of the "orders of magnitude" lies predominantly in the hardware needed for electrolysis for chemical propulsion.

	Based on body size, bacteria and elephants have similar metabolism, ecologists find
		But a new study led by Bai-Lian Li, professor of ecology at UC Riverside, shows that this is true only for organisms that are closely related evolutionarily and have body masses differing by no more than 6-7 orders of magnitude — about the difference in body mass between an elephant and a shrew.
		In other words, while metabolic activity per unit body mass varies within a group of organisms, such as mammals, it tends not to vary much when two diverse groups of organisms that differ greatly from each other in size are compared — such as bacteria and mammals.
		The new study posits, however, that living organisms are able to overcome the physical limitations imposed on them by their own physical properties and their external environment in order to maintain optimal, biochemical characteristics, such as the mass-specific metabolic rate the researchers studied.
