To the Fair Fluke!
Captain Ahab put the spyglass down on the ship\u27s table with a grunt of satisfaction. There was no doubt about it; the indistinct pale shape on the starboard horizon was Moby Dick. Was his long search at an end? Hastily he uncorked a bottle of rum and poured its contents into a tumbler. Raising this in the direction of the distant whale, he murmured to himself A toast - to the fair fluke
What Will They Think of Us?
One day, hopefully in the far-distant future, an archaeologist may come across the ruins of our American civilization that it had been. In order to do this, he may attempt to analyze the words and phrases that we used. For example, he may discover that George Dewey, an admiral in the U.S. Navy, is reputed to have said at Manila Bay, You may fire when ready, Gridley. And he may also discover that William Prescott, a Revolutionary soldier, said at Bunker Hill, Don\u27t fire until you see the whites of their eyes. As these two quotations are clearly at variance with each other in determining the proper time to fire at an adversary, he may conclude that the American people were split about 50-50 between the laissez-faire attitude of Admiral Dewey and the considerably stricter requirements laid down by Mr. Prescott. Or did the rules change drastically, depending on whether one was on land or at sea
The Strong Vs. The Weak
In the English language, verbs are divided into two groups: the strong and the weak. Weak verbs are those which simply add the letters ED onto the basic verb in order to form the other principal parts; an example is the verb WALK, WALKED, WALKED. A strong verb is one which changes its spelling in order to form the three principal parts; an example is the verb SING, SANG, SUNG
The Perils of Literal Translation
It is well known that all languages have their own peculiar idioms. Reckless translation into foreign languages can sometimes have unfortunate, and sometimes funny, consequences. This fact is amply illustrated by the following story. An engineer had once devised a program which would enable him to translate between any two languages on earth. He described his program at a technical meeting, and in order to demonstrate its power, he had a computer loaded with the new program. After describing the program, he asked the audience to suggest a phrase for him to ask the computer to translate. Someone suggested the phrase out of sight, out of mind . The engineer punched this into the machine, and then asked someone else in the audience to suggest a language that he might translate to. Someone suggested Russian. He loaded that into the machine, punched the Go button, and waited. The machine whirred for a few moments, and finally announced that the translation was such-and-such (in Russian)
Proof of Rounding by Quenched Disorder of First Order Transitions in Low-Dimensional Quantum Systems
We prove that for quantum lattice systems in d<=2 dimensions the addition of
quenched disorder rounds any first order phase transition in the corresponding
conjugate order parameter, both at positive temperatures and at T=0. For
systems with continuous symmetry the statement extends up to d<=4 dimensions.
This establishes for quantum systems the existence of the Imry-Ma phenomenon
which for classical systems was proven by Aizenman and Wehr. The extension of
the proof to quantum systems is achieved by carrying out the analysis at the
level of thermodynamic quantities rather than equilibrium states.Comment: This article presents the detailed derivation of results which were

Non-Fermi liquid angle resolved photoemission lineshapes of Li0.9Mo6O17
A recent letter by Xue et al. (PRL v.83, 1235 ('99)) reports a Fermi-Liquid
(FL) angle resolved photoemission (ARPES) lineshape for quasi one-dimensional
Li0.9Mo6O17, contradicting our report (PRL v.82, 2540 ('99)) of a non-FL
lineshape in this material. Xue et al. attributed the difference to the
improved angle resolution. In this comment, we point out that this reasoning is
flawed. Rather, we find that their data have fundamental differences from other
ARPES results and also band theory.Comment: To be published as a PRL Commen

Non-fermi-liquid single particle lineshape of the quasi-one-dimensional non-CDW metal Li_{0.9}Mo_{6}O_{17} : comparison to the Luttinger liquid
We report the detailed non-Fermi liquid (NFL) lineshape of the dispersing
excitation which defines the Fermi surface (FS) for quasi-one-dimensional
Li_{0.9}Mo_{6}O_{17}. The properties of Li_{0.9}Mo_{6}O_{17} strongly suggest
that the NFL behavior has a purely electronic origin. Relative to the
theoretical Luttinger liquid lineshape, we identify significant similarities,
but also important differences.Comment: 5 pages, 3 eps figure
