With Obtuse Spelling Rules, Pronunciation Becomes Reliant...

Since our current orthografy bears no real relation to the present pronunciation, but is at best an imperfect attempt to represent that of the Elizabethan period, English pronunciation has become almost entirely a matter of oral tradition as unsafe a gide in regard to correctness in speech as it is in regard to correctness in history. We learn to talk, and continue to talk, entirely "by ear," and with the same tendency to uncertainty and variation as do those who play music by ear. The...

 Scientists Must Always Stand at the Drawing Board

When a scientist doesn't now the answer to a problem, he is ignorant. When he as a hunch as to what the result is, he is uncertain. And when he is pretty darn sure of what the result is going to be, he is in some doubt. We have found it of paramount impor...
