Dictionary » A » Approximation ApproximationApproximation 1. The act of approximating; a drawing, advancing or being near; approach; also, the result of approximating. The largest capacity and the most noble dispositions are but an approximation to the proper standard and true symmetry of human nature. (i. Taylor) 2. An approach to a correct estimate, calculation, or conception, or to a given quantity, quality, etc. 3. (Science: mathematics) a continual approach or coming nearer to a result; as, to solve an equation by approximation. A value that is nearly but not exactly correct.

Results from our forumRe: The Colin Leslie Dean species paradox... I know exactly what a species is, and so do scientists, no matter what you say Gamila. The only point you have is that species is a taxonomic approximation. An owl defines an organism with a certain similar phenotype. They are unique and DEFINABLE. Approximations are used in chemistry also. ...

Re: Finding the net charge of amino acid... like the question was asking for such a detailed analysis of the titration curve. At pH's between the two pKa's, it is true, at least to a first approximation, that the net charge of alanine is roughly zero. It is only strictly zero at the pI. As you move away from the pI and get closer to one ...

effect of temperature on the survival of yeast cells... the yeast will denature at around 40-65 celsius, which means the colour from the indicator won't change. Do preliminary work to work out a rough approximation and take it from there. I'd suggest using a colourimeter if you can, to measure the colour density of the blue colour. @psycho_scorpyen: ...

Activation Energy and Enzyme Catalysis... activation energy (E a ) Z[A][C] = collision frequency, where Z is a constant ALSO: f = exp(-E a /RT) (Although, from what I understand this is an approximation) I also understand that the steric factor cannot be predicted, but must be calculated after experimentation. When this equation is taken ...

The Fiber Disease... crack behaviour). In order to record the migration of brine into fresh meat 23Na was imaged (Guiheneuf et al. 1997). The uptake of brine is a good approximation of a Fickian diffusion process with an Na+-concentration-dependent diffusion coefficient. Blackband and Mansfield (1986) used MRI to study ...
