(The DSB was published in 14 vol- umes in 1970–76, edited by C. C. Gillispie, New York: Charles Scribner's Sons.) I was later asked to write two more entries: for Parseval and Emil Leon Post. The entry for Post had to be done very quickly, and I could not have finished it without the generous help of one of his relatives. By the time the last of these articles was published in 1976, that for Giovanni Vailati, I had come out publicly as a homosexual and was involved in the gay liberation movement. But my article on Vailati was still discreet. If I had written it later, I would probably have included evidence of his homosexuality. The seven articles for the Dictionary of Scientific Biography have a uniform appear- ance. (The exception is the article on Burali-Forti, which I present here as I originally wrote it—with reference footnotes. -

Intellectuals Displaced from Fascist Italy Firenze University Press 2019- Guido Fubini-Ghiron Go to personal file When he was almost 60, he was expelled from the Polytechnic University of Link to other connected Lives on the move: Turin because he was Jewish. Known as one of the sharpest and most intelligent Italian analysts, he decided to continue his brilliant work on Fubini Mario Fubini Ghiron Eugenio 1 differential geometry abroad, hoping for a better future for him and his family . (Eugene) Fubini Ghiron Gino He immediately left for Paris, and soon found himself welcomed to Princeton. His two sons, expelled in Italy at the beginning of their academic career, also found their way to the USA and stayed there. Formative years in Paris He was born in Venice on 19 January 1879 to Lazzaro Fubini, a mathematics teacher at the machinist school, and to Zoraide Torre. At only nine years old, he was enrolled at Foscarini High School in Venice, achieving, in his eight years of ginnasio and liceo [junior high school and high school], perfect grades (all 10s) in mathematics2. In 1896, at seventeen years old, he enrolled in the Facoltà di Matematica [School of Mathematics] at the Scuola normale superiore of Pisa, «where many scholars became passionate about research in geometry»3. A student of Ulisse Dini, Eugenio Bertini and, above all, Luigi Bianchi, he graduated with honors in 1900 with a thesis titled «Il parallelismo di Clifford negli spazi ellittici» [Clifford’s parallelism in elliptical spaces]4. 1 Letter of 30 October 1938 from Tullio Levi-Civita to Oswald Veblen from the Institute for Advanced Study at Princeton University, translated and reported on the Università Bocconi’s website, section Rubriche <http://matematica-old.unibocconi.it> (accessed 2 February 2019). -

The Birth of Hyperbolic Geometry Carl Friederich Gauss
The Birth of Hyperbolic Geometry Carl Friederich Gauss • There is some evidence to suggest that Gauss began studying the problem of the fifth postulate as early as 1789, when he was 12. We know in letters that he had done substantial work of the course of many years: Carl Friederich Gauss • “On the supposition that Euclidean geometry is not valid, it is easy to show that similar figures do not exist; in that case, the angles of an equilateral triangle vary with the side in which I see no absurdity at all. The angle is a function of the side and the sides are functions of the angle, a function which, of course, at the same time involves a constant length. It seems somewhat of a paradox to say that a constant length could be given a priori as it were, but in this again I see nothing inconsistent. Indeed it would be desirable that Euclidean geometry were not valid, for then we should possess a general a priori standard of measure.“ – Letter to Gerling, 1816 Carl Friederich Gauss • "I am convinced more and more that the necessary truth of our geometry cannot be demonstrated, at least not by the human intellect to the human understanding. Perhaps in another world, we may gain other insights into the nature of space which at present are unattainable to us. Until then we must consider geometry as of equal rank not with arithmetic, which is purely a priori, but with mechanics.“ –Letter to Olbers, 1817 Carl Friederich Gauss • " There is no doubt that it can be rigorously established that the sum of the angles of a rectilinear triangle cannot exceed 180°. -
Chapter 5 Product Measures
Chapter 5 Product Measures Lebesgue measure on R generalizes the notion of the length of an interval. In this chapter, we see how two-dimensional Lebesgue measure on R2 generalizes the notion of the area of a rectangle. More generally, we construct new measures that are the products of two measures. Once these new measures have been constructed, the question arises of how to compute integrals with respect to these new measures. Beautiful theorems proved in the first decade of the twentieth century allow us to compute integrals with respect to product measures as iterated integrals involving the two measures that produced the product. Furthermore, we will see that under reasonable conditions we can switch the order of an iterated integral. Main building of Scuola Normale Superiore di Pisa, the university in Pisa, Italy, where Guido Fubini (1879–1943) received his PhD in 1900. In 1907 Fubini proved that under reasonable conditions, an integral with respect to a product measure can be computed as an iterated integral and that the order of integration can be switched. Leonida Tonelli (1885–1943) also taught for many years in Pisa; he also proved a crucial theorem about interchanging the order of integration in an iterated integral.

Italia, Divenni L'ultimo' Emilio Artom
Saggi e Studi ‘Ero stato uno dei primi professori medi d’Italia, divenni l’ultimo’ Emilio Artom (1888-1952) * ** ERIKA LUCIANO - LUCA LOTITO 1. Dispensati dal servizio1 Nel 2018 ricorreva l’ottantesimo anniversario della promulgazione delle leggi razziali che - com’è noto - costituiscono una delle pagine più vergognose della nostra storia recente e al contempo uno dei peggiori crimini compiuti dal regime fascista. Precedute dalla pubblicazione del Manifesto della razza e dal censimento della minoranza ebraica condotto nell’estate del 1938, le leggi razziali ratificano l'antisemitismo di Stato e privano gli ebrei italiani dei diritti politici e civili conquistati in epoca risorgimentale, condannandoli a divenire ‘una casta di paria’2. A seguito dei decreti del 5 settembre e del 17 novembre 1938, circa 170 insegnanti e presidi sono dispensati dal servizio, altrettanti professori universitari perdono la cattedra3 e sono espulsi da ogni accademia e società scientifica4, migliaia di studenti sono cacciati dalle scuole di ogni ordine e grado5 e l’uso di libri di testo di autori di razza ebraica è proibito in tutti gli istituti statali (quest’ultimo provvedimento è noto come la cosiddetta procedura di bonifica libraria)6. Le dimensioni della discriminazione sono di drammatica rilevanza per la scienza e per la matematica italiana, che perdono figure del calibro di Giuseppe Levi, Giacomo Mario Levi, Bruno Rossi, Emilio Segré, Enrico Fermi, Vito Volterra, Tullio Levi-Civita, e molti altri ancora7.

Definitions and Nondefinability in Geometry 475 2
Definitions and Nondefinability in Geometry1 James T. Smith Abstract. Around 1900 some noted mathematicians published works developing geometry from its very beginning. They wanted to supplant approaches, based on Euclid’s, which han- dled some basic concepts awkwardly and imprecisely. They would introduce precision re- quired for generalization and application to new, delicate problems in higher mathematics. Their work was controversial: they departed from tradition, criticized standards of rigor, and addressed fundamental questions in philosophy. This paper follows the problem, Which geo- metric concepts are most elementary? It describes a false start, some successful solutions, and an argument that one of those is optimal. It’s about axioms, definitions, and definability, and emphasizes contributions of Mario Pieri (1860–1913) and Alfred Tarski (1901–1983). By fol- lowing this thread of ideas and personalities to the present, the author hopes to kindle interest in a fascinating research area and an exciting era in the history of mathematics. 1. INTRODUCTION. Around 1900 several noted mathematicians published major works on a subject familiar to us from school: developing geometry from the very beginning. They wanted to supplant the established approaches, which were based on Euclid’s, but which handled awkwardly and imprecisely some concepts that Euclid did not treat fully. They would present geometry with the precision required for general- ization and applications to new, delicate problems in higher mathematics—precision beyond the norm for most elementary classes. Work in this area was controversial: these mathematicians departed from tradition, criticized previous standards of rigor, and addressed fundamental questions in logic and philosophy of mathematics.2 After establishing background, this paper tells a story about research into the ques- tion, Which geometric concepts are most elementary? It describes a false start, some successful solutions, and a demonstration that one of those is in a sense optimal. -

Robin Wilson, Notices Associate Editor In this issue of the Notices, we reflect on the sacrifices and accomplishments made by generations of African Americans to the mathematical sciences. This year marks the 100th birthday of David Blackwell, who was born in Illinois in 1919 and went on to become the first Black professor at the University of California at Berkeley and one of America’s greatest statisticians. Six years after Blackwell was born, in 1925, Frank Elbert Cox was to become the first Black mathematician when he earned his PhD from Cornell University, and eighteen years later, in 1943, Euphemia Lofton Haynes would become the first Black woman to earn a mathematics PhD. By the late 1960s, there were close to 70 Black men and women with PhDs in mathematics. However, this first generation of Black mathematicians was forced to overcome many obstacles. As a Black researcher in America, segregation in the South and de facto segregation elsewhere provided little access to research universities and made it difficult to even participate in professional societies.
