“I have divers times examined the same matter (human semen) from a healthy man... not from a sick man... nor spoiled by keeping... for a long time and not liquefied after the lapse of some time... but immediately after ejaculation before six beats of the pulse had intervened; and I have seen so great a number of living animalcules... in it, that sometimes more than a thousand were moving about in an amount of material the size of a grain of sand... I saw this vast number of animalcules not all through the semen, but only in the liquid matter adhering to the thicker part.” MenHumansLongSometimesMatterMovingScienceNumbersSawsMaterialsAmountHealthyThousandSixLong TimeBeatsSickSizeSandGrainPulseLiquidSpoiledMicroscopesLapsesGrains Of SandSick ManEjaculation Author:Antonie van Leeuwenhoek

“Suppose aliens invade the earth and threaten to obliterate it in a year's time unless human beings can find the Ramsey number for red five and blue five. We could marshal the world's best minds and fastest computers, and within a year we could probably calculate the value. If the aliens demanded the Ramsey number for red six and blue six, however, we would have no choice but to launch a preemptive attack.” IfsWorldYearsMindHumansEarthValuesChoicesHuman BeingsNumbersFiveSixComputerRedBlueAliens Author:Paul Erdos
“What had really caused the women's movement was the additional years of human life. At the turn of the century women's life expectancy was forty-six; now it was nearly eighty. Our groping sense that we couldn't live all those years in terms of motherhood alone was "the problem that had no name." Realizing that it was not some freakish personal fault but our common problem as women had enabled us to take the first steps to change our lives.” YearsFirstsHumansProblemTurnsNamesTermRealizingCommonStepsOur LivesCenturyMovementSixFaultsMotherhoodHuman LifeFortyFirst StepsEightyExpectancyLife Expectancy Author:Betty Friedan
