Null Move

Called the "null move" technique, it tells the engine to "pass" for one side. That is, to evaluate a position as if one player could make two moves in a row. If the position has not improved even after moving twice, then it can be assumed that the first move is a dud and can be quickly discarded from the search tree, reducing its size and making the search more efficient. Null moves were used in some of the earliest chess programs, including the Soviet Kaissa. It's elegant and a little ironic...

 Wheat Domesticated Homo Sapiens

Think for a moment about the Agricultural Revolution from the viewpoint of wheat. Ten thousand years ago wheat was just a wild grass, one of many, con

 Presidents Have Less Impact On Our Lives Than Those Aroun...

Presidents are royalty and we measure our lives by their reigns, but their effect on the country in general is greatly exaggerated. Take me, for example. Mr. Lyndon Johnson’s Selective Service System more or less governed my 20s, and now that I’m old and shaky, his Medicare is very helpful, but for most of us, presidents are part of the scenery, like the great stone heads on Easter Island. Millions of words have been written about Richard Nixon but his effect on my life was minuscule comp...

 Student Loans will Exceed $1 Trillion

Two things, however, are clear. The size of student debt is vast (see chart), and lots of borrowers are struggling. More than 10m students took out loans for the latest academic year, according to a report issued on October 26th by the College Board, a consortium of academic institutions. Almost a third of students graduating from college, and 69% of the ones dropping out, hold debt tied to their education. The total amount of debt is staggering. The New York Federal Reserve Bank puts it at ...

 The Big and the Little

And Mallow laughed joyously, "You've missed, Sutt, missed as badly as the Commdor himself. You've missed everything, and understood nothing. Look, man, the Empire can replace nothing. The Empire has always been a realm of colossal resources. They've calculated everything in planets, in stellar systems, in whole sectors of the Galaxy. Their generators are gigantic because they thought in gigantic fashion. "But we, – we , our little Foundation, our single world almost with...

 Knowing the World Requires Mathematics

For the things of this world cannot be made known without a knowledge of mathematics. For this is an assured fact in regard to celestial things, siDce two important sciences of mathematics treat of them, namely theoretical astrology and practical astrology. The first. . . gives us definite information as to the number of the heavens and of the stars, whose size can be comprehended by means of instruments, and the shapes of all and their magnitudes and distances from the earth, and thicknesses...

 Making Forced Connections

The basic process for making forced connections, as outlined by Koberg and Bagnall, is simple and sound. List possible features of the object you are trying to creatcte, one le feature per column. For example, the features might include cololor, size, anc shape. 2. In the column under each feature variable, list as many values for that variable as you can. For example, under color you might list all the colors of the rainbow, as well as black, white, gold, and silver. 3. Finally, random...

 The Center of the Earth

Of all regions of the earth none invites speculation more than that which lies beneath our feet, and in none is speculation more dangerous; yet, apart from speculation, it is little that we can say regarding the constitution of the interior of the earth. We know, with sufficient accuracy for most purposes, its size and shape: we know that its mean density is about 5½ times that of water, that the density must increase towards the centre, and that the temperature must be high, but beyond thes...

 Nothing Exists but Atoms

The first principles of the universe are atoms and empty space. Everything else is merely thought to exist. The worlds are unlimited. They come into being and perish. Nothing can come into being from that which is not nor pass away into that which is not. Further, the atoms are unlimited in size and number, and they are borne along in the whole universe in a vortex, and thereby generate all composite things—-fire, water, air, earth. For even these are conglomerations of given atoms. And it ...

 If We Could See the Night Sky With Eyes Like the Hubble T...

Imagine that we could see the night with eyes the size and sensitivity of the Hubble Space Telescope. How paltry then would seem our terrestrial gods, our shabby deities with human faces. How ridiculous our intolerances, how hollow our claims to have privileged access to the mind of God.
