Mascheroni was educated with the aim of becoming a priest and he was ordained at the age of 17. At first he taught rhetoric then, from 1778, he taught physics and mathematics at the seminary at Bergamo. In 1786 Mascheroni became professor of algebra and geometry at the University of Pavia, mainly on the strength of his excellent work on statics Nuove ricerche su l'equilibrio delle volte which he had published one year earlier. Later, in 1789, he became rector of the university, holding the appointment for four years. During the years 1788 to 1791 he was head of the Accademia degli Affidati. In Adnotationes ad calculum integrale Euleri (1790) Mascheroni calculated Euler 's constant to 32 decimal places. In fact only the first 19 places were correct but the remaining places were corrected by Johann von Soldner in 1809. Despite the error in the calculation, Mascheroni's work shows a deep understanding of

Home The Lorenz curve was developed by Max O. Lorenz as a graphical representation of income inequality . It can also be used to measure inequality of asset s or other distribution s. In discussions of personal income, we frequently make statements such as, "the bottom twenty percent of all households have ten percent of the total income". The Lorenz curve is based on such statements; every point on the curve represents one such statement. The Lorenz curve is a graph that shows, for the bottom x % of households, the percentage y % of the total income which they have. The percentage of households is plotted on the x -axis, the percentage of income on the y -axis. A perfectly equal income distribution in a society would be one in which every person has the same income. In this case, the bottom N % of society would always have N % of the income. Thus a perfectly equal distribution can be depicted by the straight line

Username: Password: Sites for teachers Sites for parents Awards Interactive Activities ... Sites for parents Geometric Construction with the Compass Alone Everything you can do with a ruler and a compass you can do with the compass alone. Well, not everything. For example, you can't draw straight lines using a compass. There is no talking about it. However, you can do everything reasonable. I hope you would find this claim no less remarkable. In what is known as the Geometry of Compass , a straight line is defined by any pair of two points. Starting with two points, other points can be constructed with compass alone. Thus in the following constructing a straight line means finding two points that belong to that line. Remark There are geometries in which the ruler is never used to start with. E. g., in finite geometries that only contain a finite number of points and lines, a line is just a (finite) collection of points. On the sphere, the role of straight lines is played by the great circles. The question of geometric construction with the compass alone is not concerned with such kinds of geometries. Geometry of Compass only deals with constructions in the Euclidean plane, and its basic question could be formulated as, What ruler-and-compass constructions could be accomplished with the compass alone?

Lorenzo Mascheroni Figura fondamentale nella storia dell'istruzione a Bergamo fu l'abate Lorenzo Mascheroni. Lavorò al Collegio Mariano (che diventò in seguito Liceo ) e all'Università di Pavia. Iniziò insegnando retorica, poi lettere e filosofia (questa comprendeva la logica, la metafisica e la fisica), infine matematica. A quel tempo le discipline matematiche erano ritenute le meno importanti, ma proprio il Mascheroni cercò di dare rilievo a fisica, chimica, geometria e astronomia perché aveva fiducia nel progresso delle scienze e nel metodo sperimentale iniziato da Galileo. Questo lo mise in contrasto con il clero, soprattutto con i gesuiti e il vescovo di Bergamo Dolfin. Quest'ultimo visitò le cosidette "Macchine della Misericordia" (a fianco si può ammirare un particolare della Macchina del Cosmo dell' Albricci ) con le quali si insegnavano la fisica e l'astronomia nel Collegio Mariano, ma le trovò contrarie alla religione. Da qui lo scontro con Mascheroni che se ne andò, accettando di occupare la cattedra di matematica e algebra all'Università di Pavia. Istruzione Cultura Assistenza

Glossario SCUOLE Dalla fine del 700 all’inizio dell’800 la cultura restava una prerogativa della classe dirigente (nobili, clero, borghesia).L’abate Lorenzo Mascheroni presidente della "Società di Pubblica Istruzione di Bergamo" sosteneva che l’istruzione pubblica è la base fondamentale di tutte le democrazie (proclama del 21 aprile 1797). "Noi ci professiamo i sacerdoti di questa libertà. Ma per essere liberi "bisogna conoscere particolarmente in che consiste quell’eguaglianza e quella indipendenza supremo dono della divinità, che serve tanto alla felicità de’ viventi, allorchè e’ ben diretta, e che li precipita nel baratro dell’errore e delle seduzioni allorchè è mal intesa. In breve, bisogna istruire quel popolo che d’ora innanzi dee regnar sovranamente, e che si facea rimaner avvilito nell’ignoranza allorchè era destinato a servire". Per prima cosa bisogna "sollevare" i poveri: la Società "cercherà di sollevar l’oppresso, di soccorrer la vergine pudibonda e l’orfano derelitto; ella stenderà la mano pietosa al vecchio languente, asciugherà le lacrime della vedova, e porterà i reclami di tutti i Cittadini presso le vostre autorità costituite". Il piano del Mascheroni, mai attuato, oltre a un indirizzo, prevalentemente scientifico, dei programmi, prevedeva il passaggio nelle mani dello Stato di tutti gli ordini di scuole e la contemporanea eliminazione degli istituti religiosi.
