H. L. Mencken
(12 Sep 1880 - 29 Jan 1956)

American journalist and satirist , known as 'the Sage of Baltimore,' in whose satirical reports on the Scopes trial in Tennessee the "Monkey" trial name was coined. In 19 books and thousands of essays, his writings are a treasure of wisdom couched in a sparkling wit.

H. L. Mencken's Recollections of School Algebra

A Quote on Algebra, Chemistry and Physics
and an Extraordinary Mathematics Teacher

I know a good many men of great learning—that is, men born with an extraordinary eagerness and capacity to acquire knowledge. One and all, they tell me that they can't recall learning anything of any value in school. All that schoolmasters managed to accomplish with them was to test and determine the amount of knowledge that they had already acquired independently—and not infrequently the determination was made clumsily and inaccurately.

In my own nonage I had a great desire to acquire knowledge in certain limited directions, to wit, those of the physical sciences. Before I was ever permitted, by the regulations of the secondary seminary I was penned in, to open a chemistry book I had learned a great deal of chemistry by the simple process of reading the texts and then going through the processes described. When, at last, I was introduced to chemistry officially, I found the teaching of it appalling. The one aim of that teaching, in fact, seemed to be to first purge me of what I already knew and then refill me with the same stuff in a formal, doltish, unintelligible form.

My experience with physics was even worse. I knew nothing about it when I undertook its study in class, for that was before the days when physics swallowed chemistry. Well, it was taught so abominably that it immediately became incomprehensible to me, and hence extremely distasteful, and to this day I know nothing about it. Worse, it remains unpleasant to me, and so I am shut off from the interesting and useful knowledge that I might otherwise acquire by reading.

One extraordinary teacher I remember who taught me something: a teacher of mathematics. I had a dislike for that science, and knew little about it. Finally, my neglect of it brought me to bay: in transferring from one school to another I found that I was hopelessly short in algebra. What was needed, of course, was not an actual knowledge of algebra, but simply the superficial smattering needed to pass an examination. The teacher that I mention, observing my distress, generously offered to fill me with that smattering after school hours. He got the whole year's course into me in exactly six lessons of half an hour each.

And how? More accurately, why?

Simply because he was an algebra fanatic—because he believed that algebra was not only a science of the utmost importance, but also one of the greatest fascination. He was the penmanship professor of years ago, lifted to a higher level. A likable and plausible man, he convinced me in twenty minutes that ignorance of algebra was as calamitous, socially and intellectually, as ignorance of table manners—that acquiring its elements was as necessary as washing behind the ears. So I fell upon the book and gulped it voraciously, greatly to the astonishment of my father, whose earlier mathematical teaching had failed to set me off because it was too pressing—because it bombarded me, not when I was penned in a school and so inclined to make the best of it, but when I had got through a day's schooling, and felt inclined to play.

To this day I comprehend the binomial theorem, a very rare accomplishment in an author. For many years, indeed, I was probably the only American newspaper editor who knew what it was.

Nature bears long with those who wrong her. She is patient under abuse. But when abuse has gone too far, when the time of reckoning finally comes, she is equally slow to be appeased and to turn away her wrath.

Carl Sagan Thumbnail Carl Sagan: In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) ...(more by Sagan)

Albert Einstein: I used to wonder how it comes about that the electron is negative. Negative-positive—these are perfectly symmetric in physics. There is no reason whatever to prefer one to the other. Then why is the electron negative? I thought about this for a long time and at last all I could think was “It won the fight!” ...(more by Einstein)

Richard Feynman: It is the facts that matter, not the proofs. Physics can progress without the proofs, but we can't go on without the facts ... if the facts are right, then the proofs are a matter of playing around with the algebra correctly. ...(more by Feynman)
