I also disagree about her assessment of Sylvie and Bruno, which I find wonderfully amusing. Later in life, people who knew him in childhood seem to have thought of him with great affection. Quaterions conveniently describe 3-dimensional rotations, which Bayley links to the rotation of the Hatter and the others around the tea-table. All of these are defined as particular determinants. Image from Victorian Web.

Strogatz’s first column, “From Fish to Infinity,” starts his program of “writing about the elements of mathematics, from pre-school to grad school, for anyone out there who’d like to have a second chance at the subject–but this time from an adult perspective. In doing so he brought into the world a quantity of exceptionally charming, thought-provoking writing. Without calculating engines, mathematicians are reluctant to solve systems of equations larger than about three, and for these it suffices to have a formula for the determinant, or a mnemonic for calculating it. Without Time, we are told, the characters are stuck at the tea table, constantly moving round to find clean cups and saucers. So perhaps by , quaternions were dead as you say. Carroll, whose real name was Charles Dodgson, was a very conservative, traditional mathematician, Devlin says, and he didn’t like the changes some were bringing to the discipline of mathematics. Similarly, a quaternion field has both a scalar and a vector part just like the electromagnetic field ; its spatial derivative involves the gradient of the scalar part and the divergence and curl of the vector part.

Later in life, people who knew him in childhood seem to have thought of him with great affection. He must have been a fascinating guy.

In this slice, the edges of the turquoise pentagons join centers of nearest-neighbor tetrahedra. We have no choice. Plain superficiality is the character of a speech, in which any two points being taken, the speaker is found to lie wholly with regard to those two points. The said Boole being the man who made logic as clear as algebra!

Author Lewis Carroll was also a math teacher in Oxford, England, and mathematicians say the Alice books are full of algebraic lessons — such as why a raven is like a writing desk. An explanation can be found here. Facebook Twitter Flipboard Email.

V selects four cards from a deck; A examines them, returns one to V and places the other 3 in a row on the table, some face-up, some face-down. Here part of the Archimedean tiling of the plane yellow has been superimposed on the image of 2 slices of the packing.

None of the above counts as history, of course; but disserttation is fun to speculate, and the fun disdertation not be left entirely to students of literature.

Dissertafion for the vexed question of him having been a kiddie fiddler, in thought if not in deed, I read that a recent biographer had some grounds for claiming he befriended young girls solely as a pretext to become more intimate with their mothers! After a scene-by-scene breakdown of the book the pig baby is a comment on topology, naturallyshe wraps up: Certainly less far-fetched than some of the interpretations in Aspects melnie Alice!

Bayley spends some time on the subject of quaternions, perhaps the first non-commutative algebra to catch the attention of mathematicians. Her keenness to execute everyone comes from a ghastly pun on axes — the plural of axis on a graph. Alice finds the Mad Hatter, the March Hare and the Dormouse at their tea party, but Devlin says Carroll deliberately left out one character.

Dissedtation from Natureused with permission. January 31, was the first posting in what promises to be a weekly series of columns, focused on mathematics, in the “Opinionator” blog-site of the online New York Times. We cannot get rid of that proclivity either. Without Carroll’s secret ingredient, Alice might never have achieved her fame. The diffraction pattern generated by the packed solid inset has fold rotational symmetry, known to be incompatible with spatial periodicity.

This year, for a change, we have an article by Melanie Bayley, a DPhil student in Oxford writing a thesis on Victorian literature. Their movement around the table is reminiscent of Hamilton’s early attempts to calculate motion, which was limited to rotatations in a plane before he added time to the disserttion. Patrick Brantlinger Indiana University Press, Similarly, a quaternion field has both a scalar and a vector part just like the electromagnetic field ; its spatial derivative involves the gradient of the scalar part and the divergence and curl of the vector part.

To multiply quaternions, the scalar part of the product is the product of the scalars minus the dot product of the vectors; the vector part is the sum of the vector part of each quaternion multiplied by the scalar part of the others, plus the cross product of the vectors.

Wish I could comment on quaternions and relativity, but it would take several pages! It is easy to see how a conservative mathematician would be troubled by this. However, there are quaternionic formulations of Special Relativity.
