The Noble Person is Like an Echo
君子之學也，入乎耳，著乎心，布乎四體，形乎動靜。端而言，蝡而動，一可以為法則。小人之學也，入乎耳，出乎口；口耳之間，則四寸耳，曷足以美七尺之軀哉！古之學者為己，今之學者為人。君子之學也，以美其身；小人之學也，以為禽犢。故不問而告謂之傲，問一而告二謂之囋。傲、非也，囋、非也；君子如嚮矣。
1 [Translated] The learning of the noble person enters his ear, is stored in his mind, spreads through his four limbs, and is made visible in his activity and his tranquility. In his smallest word, in his slightest movement, in everything, he may be taken as a model and a standard. The learning of the lesser man enters his ear and comes out his mouth. With only four inches between ear and mouth, how can he possess it long enough to beautify a seven-foot body In antiquity learning was carried on for the sake of one’s self; today learning is carried on for the sake of others.The learning of the noble person is for the sake of beautifying himself; the learning of the lesser man is offering bird and beast [to win attention from others]. Thus to proffer information when you have not been asked for it is called officiousness; to proffer information on two questions when you have only been asked about one is garrulity. Officiousness is to be condemned, so too is garrulity. The noble person is like an echo.
The Unique Properties of Ice
By the standard of other substances, the properties of ice are bizarre, yet ice is so perfectly suited to our purpose that if it didn't exist we should have to invent it. With few exceptions, the solid phase of matter is more dense than the liquid phase; water. alone among common substances, violates the rule. As water begins to cool, it first contracts and becomes more dense, in the typical way. But about four degrees above the freezing point, something peculiar happens. It ceases to contrac...Frozen water works so perfectly for life on Earth.
Guy Steele on Base Ten and Base Two
If I could change one thing—this is going to sound stupid—but if I could go back in time and change one thing, I might try to interest some early preliterate people in not ! using their thumbs when they count It could have been the Standard, and it would have made a whole lot of things easier in the modem era. On the other hand, we have learned a lot from the struggle with the incompatibility of base-ten with powers of two. 
notesOur Base ten number system is the bane of computer scientists.
