Learn One Thing A Day

Today I learnt that the famous saying " one swallow does not make a summer " is a quotation of Aristotle (384-322 BCE) and is contained in his work The Nicomachean Ethics. In addition, it is part of a much longer and nicer sentence:   One swallow does not make a summer, neither does one fine day; similarly one day or brief time of happiness does not make a person entirely happy. (Roman copy in marble of a Greek bronze bust of Aristotle by Lysippus, c. 330 BCE. The alabaster mantle is modern. From wikipedia )

Today I heard one of the three famous " laws " of the British science (fiction) writer Arthur Charles Clarke (1917 - 2008) and I have thought to the report  them here :) ( image source ) When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong. The only way of discovering the limits of the possible is to venture a little way past them into the impossible. Any sufficiently advanced technology is indistinguishable from magic. The third sentence is probaly the most famous one and if you look around you, its value and validity will appear still extremely relevant, don't you think?
