    Extractions: Automata theory, formal languages, combinatorics of words McNaughton entered computer science in the 1950s after teaching philosophy for six years. His career switch was due to the lean job market more than anything else. Today, however, his training in philosophy holds him in good stead. McNaughton, who is author of the textbook Elementary Computability, Formal Languages and Automata published by Prentice-Hall, is now looking at problems in the combinatorics of words, a branch of formal languages. Formal languages deal with symbolic logic and computer languages as opposed to the natural languages used in human speech and general-purpose writing. His research is being coordinated with computer scientists formerly at the GE Research and Development Center in nearby Niskayuna, New York. This group at GE was called the Theorem Proving Group. Members of this group are now in the Computer Science Department at the University at Albany and in the Computer Science Department at RPI. Their research was concerned with looking at formal linguistic systems for the sake of carrying through proofs on the machine. For example, they have looked at ways to improve the efficiency of Thue systems, a linguistic method developed by Norwegian logician Axel Thue in 1914. Thue systems are useful for computation because they replace strings (connected characters) with other strings, carrying through a rather basic kind of computer operation.

Baker attended University College, London (B.S., 1961), and Trinity College, Cambridge (M.A. and Ph.D., 1964). He held an appointment at University College (1964-65) and then joined the faculty of Trinity College in 1966. Baker received the Fields Medal at the International Congress of Mathematicians in Nice, France, in 1970. His work with diophantine equations provided an advance over previous work in an area that a few years earlier had been shown to hold limited possibilities for success. Following work by Axel Thue, Carl Ludwig Siegel, and Klaus Friedrich Roth, Baker showed that for f x y m f x y ), an irreducible binary form of degree n ? 3 with integer coefficients, m being a positive integer, there is an effective bound B depending only on n and on the coefficients of f , so that max x y B , for any solution ( x y ). Thus, at least in theory, it is possible to determine all the solutions explicitly for a large class of equations. This work was related to Baker's considerable generalization of the Gelfond-Schneider theorem (Hilbert's seventh problem) that states that, if

Along with several other celebrated theorems of logic it sets mathematics apart from all other human endeavors - unlike in physics, economy or history, we mathematicians know our foundations. We have an extremely good collection of axioms so we know what we can do. And we even know, quite for sure, what we will never be able to do - prove all that is right, for one. Gödel's theorem is famed even outside of math, yet not enough of us know how easy it is. Indeed, here's that statement that is true and yet unprovable: This Statement Has No Proof Self reference?

    Extractions: Here it is the succession of PhD advisers and students that goes backwards in time from my own degree. For the later entries it is not clear that there was a formal advisor/student/degree relationship, but there is evidence that one person was influenced in their education by the other. It seems odd that [TCSG] lists Ore as a student of Skolem, with Ore's degree awarded in 1924 while [BDM] lists Skolem's degree as being given in 1926. The following quotes are from articles in the Biographical Dictionary of Mathematicians [BDM]: Skolem: "In the latter year [1916] he returned to Oslo, where he was made Dozent in 1918. He received his doctorate in 1926." (H. Oettel, p. 2296) Thue: "Thue enrolled at Oslo University in 1883 and became a candidate for the doctorate in 1889." (Viggo Brun, p. 2460)

    Extractions: Starting thoughts... This rant has to do with the number 3. Let me begin by telling a story so you can see where my interest in the number 3 comes from. When I was a physics undergraduate student, I used to watch and drool over the studies of a friend of mine who was in the Master's program. I learned to really appreciate my studies by seeing how he was applying the basics of what I was learning to solving really neat problems. One Friday I wandered into the lab where three of them were grinding through the solution of some complex electromagnetic equations. The solution was so complex that they had divided the work up among themselves and had been busy filling page after page of large computer printout paper abscounded from the computer center (this was back in 1970, mind you...). Well it was a sight for a young impressionable lad such as myself to watch. I sat there for hours just watching them grind through their solutions. I was impressed. But, soon I heard the call of the local pub and wandered off to play. Late Sunday afternoon, I went back to see how they were doing. Much to my surprise, they were all jumping up and down and yelling and screaming. Crumpled computer paper was

However, if you're packing your shelves neatly, with all the tins in a line (called a 'regular' array), you're ignoring what Axel Thue, the Norwegian mathematician, taught us in the early 1900's: the densest packing of round items is hexagonal, not linear. In the shelf of baked beans below, we fit in 48 tins when packing regularly.

Acting/Theatre Andres Segovia [1893-1987], from Spain, was the most famous guitarist of all time. He brought the classical guitar from its folk- and dance-related image to the symphonies and concert halls of the most established musical prominence. He developed an approach to plucking the guitar strings with the fingernails of the right hand, which became the dominat school of guitar, displacing the gentler and more lyrical Neapolitan school which used the fingertips. Christopher Parkening is arguably the greatest American performer of Classical Guitar. After a year of intensive Classical Guitar at Brookdale Community College, under Christopher Parkening's master student Barry Eisner, I was able to play a few baroque pieces and original compositions at community college concerts, and then retired to the occasional original song at Woodstock, various parties and resorts, and while hitchiking across America, singing for my supper.

    Extractions: by Sherman Stein Sherman Stein, author of a calculus textbook, a monograph on the theory of tiling, a study of Archimedes , and Strength in Numbers (the latter two previously reviewed on MAA Online ), here presents another installment of mathematics for the general public. How the Other Half Thinks: Adventures in Mathematical Reasoning consists of eight short chapters, each of which sets up and then solves a nontrivial mathematical problem. Proofs from THE BOOK Chapters 2 and 4 deal with random strings of a's and b's. In Chapter 2, Stein asks how long such a string must be before the number of occurrences of one of the letters exceeds the number of occurrences of the other by 2. The expected value of this length is given by an infinite series. Stein evaluates the series by a clever rearrangement which goes back to the 14th century scholastic Nicole Oresme. The same series occurs in Chapter 4, where Stein computes the expected length of a run of a's or b's. Another problem about probability is treated in Chapter 6: in an election involving two candidates, what is the probability that one candidate will lead during the entire count? The solution here is based on a geometric reflection argument.

In his book De nive sexangula (`On the six-sided snowflake') of 1611, Kepler asserted that the packing in three dimensions made familiar to us by fruit stands (called the face-centred cubic packing by crystallographers) was the tightest possible: Coaptatio fiet arctissima: ut nullo praetera ordine plures globuli in idem vas compingi queant.
