“Mathematics is not arithmetic. Though mathematics may have arisen from the practices of counting and measuring it really deals with logical reasoning in which theorems-general and specific statements-can be deduced from the starting assumptions. It is, perhaps, the purest and most rigorous of intellectual activities, and is often thought of as queen of the sciences.” MayScienceDealsPracticeActivityIntellectualAccountsMathematicsStartingStatementsQueensAssumptionReasoningLogicalCountingMeasuringArithmeticTheoremsLogical Reasoning Author:Christopher Zeeman
“If it is possible to have a linear unit that depends on no other quantity, it would seem natural to prefer it. Moreover, a mensural unit taken from the earth itself offers another advantage, that of being perfectly analogous to all the real measurements that in ordinary usage are also made upon the earth, such as the distance between two places or the area of some tract, for example. It is far more natural in practice to refer geographical distances to a quadrant of a great circle than to the length of a pendulum.” IfsMadeTwoRealSeemsEarthScienceNaturalPracticeTakenExampleDependsOffersOrdinaryAdvantageAreasDistanceDefinitionsCirclesLengthQuantityUnitsMeasurementLinearUsagePendulums Author:Nicolas de Caritat, marquis de Condorcet
“I ran into the gigantic and gigantically wasteful lumbering of great Sequoias, many of whose trunks were so huge they had to be blown apart before they could be handled.
