He that in ye mine of knowledge deepest diggeth, hath, like every other miner, ye least breathing time, and must sometimes at least come to terr. alt. for air.
Isaac Newton
Time
Absolute, true, and mathematical
Absolute, true, and mathematical time, in and of itself and of its own nature, without reference to anything external, flows uniformly and by another name is called duration. Relative, apparent, and common time is any sensible and external measure (precise or imprecise) of duration by means of motion; such as a measure-for example, an hour, a day, a month, a year-is commonly used instead of true time.
Isaac Newton
A mind is accustomed
A mind is accustomed to mathematical deduction, when confronted with the faulty foundations of astrology, resists a long, long time, like an obstinate mule, until compelled by beating and curses to put its foot into that dirty puddle.
Johannes Kepler
Truth is the daughter
Truth is the daughter of time, and I feel no shame in being her midwife.
Johannes Kepler
Bad times, hard times
Bad times, hard times, this is what people keep saying; but let us live well, and times shall be good. We are the times: Such as we are, such are the times.
Saint Augustine
