To help celebrate the year of the horse, join us on Saturday, February 8th at the Chatham Square Library between 10am and 5pm as we give you a chance to record your Lunar New Year stories!These stories will be part of the collection at Chatham Square Library and you’ll receive a CD to bring home after your conversation too. What a great way to save your memories for future generations to listen to!
As conscious beings, we are constantly aware of the relentless march of time. You can make an egg into an omelet, but you can’t turn an omelet back into an egg. Dropped glasses shatter and do not reassemble themselves. Above all, we age and become decrepit; there is no return to youth. But this is a great scientific mystery. There is nothing in the form of the laws of nature at the fundamental microscopic level that distinguishes a direction of time. They are time-symmetric. But the behavior of macroscopic objects around us is subject to the famous second law of thermodynamics, according to which disorder (as measured by entropy) always increases with time. This puts a direction, or arrow, of time into phenomena. The classical studies by Maxwell and Boltzmann in the second half of the 19th century assumed the existence of atoms and showed, on the basis of reasonable laws, that non-uniform distributions of atoms would always have a tendency to be washed out into a state with a uniform temperature distribution. This initial work took no account of gravity. Gravity presents many puzzles because it gives rise to “anti-thermodynamic” behavior: Under its influence, uniformly distributed matter tends to break up into clusters. As of now, no one knows how to describe this behavior using an entropy-type concept. This is all the more puzzling because Einstein’s wonderful theory of gravity—his general theory of relativity—does show that when black holes form they do have thermodynamic properties and possess a colossal entropy. What no one has been able to do is define gravitational entropy for the rest of the universe.
Librairan Miranda at Grand Concourse Library shares a favorite book with… wait for it… cat poems! Happy Caturday!
I love the cat breed illustrations on the inside of the front and back covers of this book. All of the cats look so happy! The book is full of poems that indicate the nature of cats, and anyone who has experience with cats or who has lived with cats knows exactly what Crawley is talking about in these cat poems.
