Kesäaika päättyy! Talviaika alkaa...
Aika, mitä se on?
Jospa aika on vain sitä mitä ihminen tekee siitä, aivan kuten elämäkin.
http://fi.wikipedia.org/wiki/Aika
Aurinko nousee,
On kastetta maassa.
Aika on herätä,
Nousta ja lähteä,
Kohdata ystävä kallehin.
refrain:
Niin kaunis on maa,
Niin korkea taivas.
Soi lintujen laulusta kukkiva kunnas
Ja varjoisat veet,
Niin varjoisat veet.
Niin kaunis on maa,
Niin korkea taivas.
Soi lintujen laulusta kukkiva kunnas
Ja varjoisat veet,
Niin varjoisat veet.
Päivä on kirkas,
Vain metsässä tuulee.
Aika on naurun
Ja leikin ja riemun.
Mukana ystävä kallehin.
Vain metsässä tuulee.
Aika on naurun
Ja leikin ja riemun.
Mukana ystävä kallehin.
refrain
Aurinko laskee,
Jo pitenee varjot.
Aika on eron ja jäähyväisten.
Poissa on ystävä kallehin.
Jo pitenee varjot.
Aika on eron ja jäähyväisten.
Poissa on ystävä kallehin.
refrain

The End of Time Fyysikko Julian Barbour
"Aikaa ei ole olemassa."

Oxford University Press, 2001 - 384 sivua
Richard Feynman once quipped that "Time is what happens when nothing else does." But Julian Barbour disagrees: if nothing happened, if nothing changed, then time would stop. For time is nothing but change. It is change that we perceive occurring all around us, not time. Put simply, time does not exist.
In this highly provocative volume, Barbour presents the basic evidence for a timeless universe, and shows why we still experience the world as intensely temporal. It is a book that strikes at the heart of modern physics. It casts doubt on Einstein's greatest contribution, the spacetime continuum, but also points to the solution of one of the great paradoxes of modern science, the chasm between classical and quantum physics. Indeed, Barbour argues that the holy grail of physicists--the unification of Einstein's general relativity with quantum mechanics--may well spell the end of time.
Barbour writes with remarkable clarity as he ranges from the ancient philosophers Heraclitus and Parmenides, through the giants of science Galileo, Newton, and Einstein, to the work of the contemporary physicists John Wheeler, Roger Penrose, and Steven Hawking. Along the way he treats us to enticing glimpses of some of the mysteries of the universe, and presents intriguing ideas about multiple worlds, time travel, immortality, and, above all, the illusion of motion.

The End of Time is a vibrantly written and revolutionary book. It turns our understanding of reality inside-out.
