POPSIs Wiki going weaky? "If the site grants new powers to editors, it would bring Wikipedia even closer to traditional encyclopedia websites such as Britannica, which last week announced that it would be launching a new online version that would allow readers to submit their own updates to entries. That change came after a bitter war of words, following a 2005 study by science journal Nature that found Wikipedia and Britannica were often comparable for accuracy - and in some cases, Wikipedia won."

POPSIt's snowing on Mars ... Mars: the facts Mars is the fourth rock from the sun and our outer neighbor in the solar system. Mars has two moons, named Phobos and Deimos, Greek for "fear" and "panic". They were named after the horses that pulled the chariot of the Greek war god Ares. Mars is nearly half the size of Earth but around one tenth the mass. Mars and Earth have the same land surface area. The gravity on Mars is a third of that on Earth. The Martian year lasts 687 Earth days, and each Martian day is 40 minutes longer. The Martian atmosphere is 95% carbon dioxide, 2.7% nitrogen and 0.13% oxygen. Mars has no magnetic field, so the surface is constantly bombarded by radiation from the sun. What an adventure!

POPSNatural selection "How fleeting are the wishes and efforts of man! how short his time! and consequently how poor will his products be, compared with those accumulated by nature during whole geological periods. Can we wonder, then, that nature's productions should be far "truer" in character than man's productions; that they should be infinitely better adapted to the most complex conditions of life, and should plainly bear the stamp of far higher workmanship?" "We see nothing of these slow changes in progress, until the hand of time has marked the long lapse of ages, and then so imperfect is our view into long past geological ages, that we only see that the forms of life are now different from what they formerly were." beautifully written. i think that even in the course of ones own life, one can often be so blind to the processes that shape and dictate his perception. A different poetry of existence is needed.
