Invention Timeline - Exodus, Greek Astronomer; Determined Length of the Year
Lived about 370 B. C.
Greek astronomer. Pliny informed us that he determined the length of the year at 365 1/4 days. He is also said to have originated the doctrine of the concentric solid crystalline spheres, by which the apparent motions of the sun, the moon and the planets were explained. His works are not extant.
What a solemn and striking admonition to youth
is that inscribed on the dial at All Souls, Oxford-
periunt et imputantur-the hours perish and are
laid to our charge: for time, like life, can never be
recalled. Melancthon noted down the time lost by
him that he might reanimate his industry, and not
lose an hour.
—Samuel Smiles
Every moment you now lose is so much character
and advantage lost; as, on the other hand, every
moment you now employ usefully, is so much time
wisely laid out, at prodigious interest.
—Lord Chesterfield
The hours of a wise man are lengthened by his
ideas, as those of a fool are by his passions. The
time of the one is long, because he does not know
what to do with it; so is that of the other, because
he distinguishes every moment of it with useful or
amusing thoughts; or, in other words, because the
one is always wishing it away, and the other always
enjoying it.
—Addison
