A Computer Algorithm for Randomization

Back in the early days of computers, one of the more popular methods of generating a sequence of random numbers was to employ the following scheme: 1. Choose a starting number between 0 and 1. 2. Multiply the starting number by 4 ("stretch" it). Subtract 4 times the square of the starting number from the quantity obtained in step 2 ("fold" the interval back on itself in order to keep the final result in the same range). 3.Given a starting number between 0 and 1, we can use the proce-dureâ€...

 Knowledge Grows Faster Than Compound Interest

Remember that accumulated knowledge, like accumulated capital, increases at compound interest: but it differs from the accumulation of capital in this; that the increase of knowledge produces a more rapid rate of progress, whilst the accumulation of capital leads to a lower rate of interest. Capital thus checks its own accumulation: knowledge thus accelerates its own advance. Each generation, therefore, to deserve comparison with its predecessor, is bound to add much more largely to the commo...

 Christmas is Not Christian

I have decked my soundproof booth with boughs of holly and, of course, poinsettia or, some say, poin-settia. Though it is actually pronounced pon-see-ha. Did you know that it is a Mexican plant? It is. Named for the ambassador to Mexico, James Poinsett, it was brought to our country in 1828 and quickly became favored over its predecessor, the Christ-odendron. Some might argue we've ended up with an inferior, less godly plant. But in fact, history shows us so little of Christmas is actually C...

 Rocks Contain Impressions of Irreversible Events

Historical chronology, human or geological, depends... upon comparable impersonal principles. If one scribes with a stylus on a plate of wet clay two marks, the second crossing the first, another person on examining these marks can tell unambiguously which was made first and which second, because the latter event irreversibly disturbs its predecessor. In virtue of the fact that most of the rocks of the earth contain imprints of a succession of such irreversible events, an unambiguous working ...
