## The *Alice* Books

The two books that are perhaps the most famous children’s books of the Victorian Era were written by an unlikely author. Charles Lutwidge Dodgson (pronounced DOD-son–the “g” is silent) was an Oxford don–a professor of mathematics, specifically–a skilled amateur photographer, and a deacon in the Church of England. Despite the expectations of his father, Dodgson did not emulate him by going on to the priesthood. Rather, taking advantage of an exemption made for him by the dean of the college, Dodgson remained at Christ Church College, Oxford, for the rest of his life, lecturing in mathematics and occasionally preaching sermons as a deacon.

Dodgson never married nor had children of his own. However, throughout his life he had many child-friends, mostly young girls. One in particular, Alice Pleasance Liddell, made him famous. Alice was the daughter of Henry George Liddell, dean of Christ Church, and a formidable classical scholar (he was co-author of Liddell and Scott’s* Greek-English Lexicon*, still in use after 175 years). Dodgson became friends with Alice and her two sisters closest in age to her, Lorina and Edith. They would often go on excursions, during which the girls would plead with Dodgson to tell them stories. He was always happy to comply. On one such excursion in 1862–memorialized by Dodgson as the “golden afternoon“–Dodgson, accompanied by his friend the Reverend Robinson Duckworth, took the three girls on a boat ride down the Isis River.

As usual, Dodgson, at the girls’ request, told one of his stories. This time, at the end of the day, Alice implored Dodgson to write it down. Eventually he did so and presented the result, *Alice’s Adventures Underground*, to Alice Liddell. Later, at the suggestion of his friend George MacDonald, he expanded and reworked the book for publication. The result, *Alice’s Adventures in Wonderland*, published in 1865 under the pen name Lewis Carroll (by which Dodgson is usually known), was a sensation, and has never been out of print since. In 1871 Dodgson published the equally well-known sequel, *Through the Looking-Glass and What Alice Found There*. In 1876 he published the long comic poem *The Hunting of the Snark*, which, in modern parlance, takes place in the same universe as the *Alice* books; and in 1895 he published the two-part children’s novel *Sylvie and Bruno. Sylvie and Bruno* is largely forgotten, considered by most to be Dodgson’s weakest work. The *Alice* books, along with *The Hunting of the Snark*, are his masterpieces.

## Omar Khayyám

Appropriately, I begin this series with the patron of this blog, غیاث الدین ابوالفتح عمر بن ابراهیم خیام نیشابورﻯ, in proper Persian transcription, Ghiyāth ad-Din Abu’l-Fatḥ ‘Umar ibn Ibrāhīm al-Khayyām Nīshāpūrī. In the West, though, he’s most commonly known as Omar Khayyám (in the Victorian era, when Edward FitzGerald’s famous translation of Omar’s poetry became wildly popular, the custom for indicating long vowels in Persian transcription was to use the acute accent; nowadays, the macron is preferred; hence, “Khayyám” vs “Khayyām”).

Omar is best known in the west as the author of the *R**ubáʿiyát*. This is the plural of *r**ubáʿi*, which simply means “quatrain” (a verse of four lines). The *r**ubáʿi* was a very popular genre of verse in Persia, and hundreds of *r**ubáʿiyát* are attributed to Omar. Beginning in 1859, the English poet Edward FitzGerald translated a number of the *r**ubáʿiyát* attributed to Omar, publishing them under the title *The R ubáiyát of Omar Khayyám* (for keen-sighted readers, I’m not being inconsistent. The apostrophe, representing the glottal stop, should properly be between the first “a” and the “i” in

*r*

*ubáʿiyát*–thus, it’s pronounced “roo-BAH-ee-yaht”, not “roo-BYE-yaht”. However, FitzGerald left it out, for whatever reason. Thus, when I print the title as he gave it, I’m following suit; but when discussing the genre as such, I’m leaving the glottal stop in). Over the remainder of his life, FitzGerald produced five editions of the

*R*. This book became immensely popular in the Victorian age, and while less well-known now, it is still moderately popular, and has never been out of print.

*ubáiyát*## Quote for the Week

Pure mathematics consists entirely of assertions to the effect that, if such and such a proposition is true of anything, then such and such another proposition is true of that thing. It is essential not to discuss whether the first proposition is really true, and not to mention what the anything is, of which it is supposed to be true. Both these points would belong to applied mathematics. We start, in pure mathematics, from certain rules of inference, by which we can infer that if one proposition is true, then so is some other proposition. These rules of inference constitute the major part of the principles of formal logic. We then take any hypothesis that seems amusing, and deduce its consequences. If our hypothesis is about anything, and not about some one or more particular things, then our deductions constitute mathematics. Thus mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true. People who have been puzzled by the beginnings of mathematics will, I hope, find comfort in this definition, and will probably agree that it is accurate.

## The Apple and the Multiverse, Revisited: The Emanations of God

We left off last time with hints of fascinating implications of the idea of God making the universe by His emanations. To refresh, we noted that “creation” implies making something *ex nihilo*–out of nothingness. The thing so created is existentially separate from God, although, according to Thomist thought, at least, it requires His ongoing action to continue in existence. By contrast, “emanation” implies a “flowing into”, whereby a “part” of God “flows into” what He makes, bringing it into existence. In a sense, the things emanated are not existentially or ontologically separate from God. Let’s look at this latter mode of making a universe in more detail.

First, it’s necessary to point out that no amount of emanation–no amount of “flowing out”–ever exhausts God’s essence. A reservoir has a limited amount of water to flow out into irrigation channels, to households, and so on. Let out too much and it will be left dry. Likewise, if I keep pinching smaller lumps of clay off of a larger lump, sooner or later there will be no large lump left. It doesn’t work that way with God, though–there’s no limit to the number of beings or entities (the technical theological term is “creature”–we use it to mean animals, but literally, “creature” means anything, animal, vegetable, or mineral, that has been created. It is in this sense that I’ll use the term here) which He can emanate. This is simply because God is infinite.

… es ist wahr, ein Mathematiker, der nicht etwas Poet ist, wird nimmer ein vollkommener Mathematiker sein.

… it is true that a mathematician who is not somewhat of a poet, will never be a perfect mathematician.

## Quote for the Week

Whoever thinks algebra is a trick in obtaining unknowns has thought it in vain. No attention should be paid to the fact that algebra and geometry are different in appearance. Algebras (

jabbreandmaqabeleh) are geometric facts which are proved by propositions five and six of Book two ofElements.

–As quoted in “A Paper of Omar Khayyam” by A.R. Amir-Moez in *Scripta Mathematica* 26 (1963). This quotation has often been abridged in various ways, usually ending with “Algebras are geometric facts which are proved”, thus altering the context significantly. Courtesy of Wikiquote.

## Quote for the Week

I was unable to devote myself to the learning of this algebra and the continued concentration upon it, because of obstacles in the vagaries of time which hindered me; for we have been deprived of all the people of knowledge save for a group, small in number, with many troubles, whose concern in life is to snatch the opportunity, when time is asleep, to devote themselves meanwhile to the investigation and perfection of a science; for the majority of people who imitate philosophers confuse the true with the false, and they do nothing but deceive and pretend knowledge, and they do not use what they know of the sciences except for base and material purposes; and if they see a certain person seeking for the right and preferring the truth, doing his best to refute the false and untrue and leaving aside hypocrisy and deceit, they make a fool of him and mock him.

## Quote for the Week

By the help of God and with His precious assistance, I say that Algebra is a scientific art. The objects with which it deals are absolute numbers and measurable quantities which, though themselves unknown, are related to “things” which are known, whereby the determination of the unknown quantities is possible. Such a thing is either a quantity or a unique relation, which is only determined by careful examination. What one searches for in the algebraic art are the relations which lead from the known to the unknown, to discover which is the object of Algebra as stated above. The perfection of this art consists in knowledge of the scientific method by which one determines numerical and geometric unknowns.

## 2+2=…uh, wait, let me grab my calculator….

This is an essay originally written about seven years ago. The subject matter is just as pertinent, if not more so.

Over the last month I have been working every other day as a substitute teacher. I am currently working towards secondary school certification so I can teach full-time in the public schools at the high school level. Of course, I’ve taught for seventeen years, but I still need that piece of paper for the public schools…but don’t get me started on that…. Anyway, most recently I taught for six years at a proprietary (i.e. for-profit) two-year college. It was during this time that I discovered that proprietary colleges are the tool of Satan. Don’t get me started on that, either. Anuway, as you may guess, doing the proprietary college thing didn’t work out, and it’s time for a change. Thus, partly for continued income (always a good thing, especially if you’ve got a mortgage, a toddler, and four cats!) and partly to get my foot in the door, I’ve been subbing at the high school and middle school in the town where I live. Next semester, when I will be taking all night classes at college, I hope to substitute every day, rather than every other day, as now. Meanwhile, even subbing every other day has provided some interesting insights.

My field is mathematics–let me point that out right away. Also, let me point out a few other things. First, I’m a mediocre mathematician–I’m not even fit to unlace John Nash’s shoes, mathematically speaking. I’m a damn good math *teacher *though. Though I actually *am* an arrogant bastard, that’s not boastful blather, but a reasonable hypothesis based on seventeen years of consistently good performance evaluations–except for one from the aforementioned Satanic college, which according to a friend in the know there, was political; but don’t get me started on *that!*–and testimonials by former students. I know my weaknesses, though, and as I said, I am a mediocre mathematician. I graduated from a state university not known as a training ground for great mathematicians, and before that I graduated from a high school of only about 800 (graduating class of 160). I was raised in a very small town of a population roughly equal to the student body of my high school (which was, obviously, in a different town). The point is, mathematically, both in aptitude and training, I am nothing special, to say the least. Read the rest of this entry
