There were three-dimensional chess games in which eight transparent boards were placed one over the other and in which each piece moved in three dimensions as they formerly moved in two, and in which the number of pieces and pawns were doubled, the win coming only when a simultaneous check of both enemy kings occurred. There were even the popular varieties, in which the original position of the chessmen were decided by throws of the dice, or where certain squares conferred advantages or disadvantages to the pieces upon them, or where new pieces with strange properties were introduced.

The sum of human knowing is beyond any one man; any thousand men. With the destruction of our social fabric, science will be broken into a million pieces. Individuals will know much of the exceedingly tiny facets of which there is to know. They will be helpless and useless by themselves. The bits of lore, meaningless, will not be passed on. They will be lost through the generations. But, if we now prepare a giant summary of all knowledge, it will never be lost. Coming generations will build on it, and will not have to rediscover it for themselves. One millennium will do the work of thirty thousand.
