(Stewart) "By the pure reason I mean the power by which we become possessed of principles." (Coleridge) "The sense perceives; the understanding, in its own peculiar operation, conceives; the reason, or rationalized understanding, comprehends." (Coleridge) 3.

(Milton) "The most probable way of bringing France to reason would be by the making an attempt on the Spanish West Indies." (Addison) 4. <mathematics> Ratio; proportion.

(Bacon) Synonym: Motive, argument, ground, consideration, principle, sake, account, object, purpose, design. See Motive, Sense. Origin: OE. Resoun, F. Raison, fr. L. Ratio (akin to Goth.

| Reaumur scale | A thermometer scale in which each degree Reaumur (캲) is 1/80 of the temperature difference between the freezing point and boiling point of pure water at 1 atmosphere pressure, with 0캲 set at the freezing point and 80캲 set at the boiling point of water. (05 Mar 2000) |

| reading frame |
A series of triplets beginning from a specific nucleotide. Each triplet is represented by a single amino acid in the protein synthesized. The reading frame defines which sets of three nucleotides are read as triplets in the DNA, and hence as codons in the corresponding mRNA; this is determined by the initiation codon, AUG. Thus the sequence AUGGCAAAAUUUCCC would read as AUG/GCA/AAA/UUU/CCC/ and not as A/UGC/CAA/AAU/UUC/CC. ...
