Dictionary » I » Inverse



1. Opposite in order, relation, or effect; reversed; inverted; reciprocal; opposed to direct.

2. (Science: botany) Inverted; having a position or mode of attachment the reverse of that which is usual.

3. (Science: mathematics) opposite in nature and effect; said with reference to any two operations, which, when both are performed in succession upon any quantity, reproduce that quantity; as, multiplication is the inverse operation to division. The symbol of an inverse operation is the symbol of the direct operation with -1 as an index. Thus sin -1 x means the arc whose sine is x.

(Science: geometry) inverse figures, two points lying on a line drawn from the center of a fixed circle or sphere, and so related that the product of their distances from the center of the circle or sphere is equal to the square of the radius.

(Science: mathematics) inverse, or reciprocal, ratio, the ratio of the reciprocals of two quantities. Inverse, or reciprocal, proportion, an equality between a direct ratio and a reciprocal ratio; thus, 4: 2:: 1/3: 1/6, or 4: 2:: 3: 6, inversely.

Origin: L. Inversus, p. P. Of invertere: cf. F. Inverse. See invert.

Graphs depicting qPCR fold change

... values >1 represent up-regulation. But the problem with this method is that it is harder to appreciate the extent of down-regulation. 2. Using inverse values where negative values (<-1) represent down-regulation and positive values (>+1) represent up-regulation. However, the problem with ...

Re: Theories - Origin of Life

... when new species appear with new adaptations. The reason for this is that the rate of evolution of a population is roughly proportional to the inverse square root of the population size. So big steps are most likely when populations are small, giving rise to the "punctuated equilibrium'' ...

Molarities, concentrations and ratios

... Second one is less clair if sol C is 3 uM, is more diluted than 300mM so never you can get a 300mM sol starting of 3uM sol. But the inverse yes you can obtain a 3uM sol from a 300mM one. 300mM=300000uM so diluting 100000times you will get a 3 uM sol., so for 50ml you have to add ...

Re: Future Human Evolution

... objective and numerical measure of 'natural-ness', we could draw a graph of human lifespan versus naturalness over time, which would show an exact inverse correlation. ie. The less natural our conditions, the longer we live. This relationship is very long term ( at least 10,000 years to the invention ...

Re: Calculating Enzymatic Rate

... manipulate the data. In my image below, I show your original data and then another graph where I changed it. What I did was take time and use the inverse of it or 1/t and took the log of H2O broken down. So now the graph is linear. This is probably overkill for what your doing though. http://usera.ImageCave.com/smacklemeelmo/graph.gif.jpg ...
