Development Of Geometry And Its Assistance In Promoting Society, Nelson Jean May 1932

Development Of Geometry And Its Assistance In Promoting Society, Nelson Jean

Electronic Theses and Dissertations

This bachelor’s thesis, presented to Xavier University in 1932, traces the history of geometry and argues that the subject has contributed to the development of society. Jean begins with geometry’s origins in practical needs in ancient Egypt, such as land division and taxation after the flooding of the Nile. He then follows its development through the Greeks, giving particular attention to Thales, Pythagoras, and the third-century mathematicians Euclid, Archimedes, and Apollonius.

Jean also discusses the educational and cultural value of geometry and its practical uses in physics, mechanics, architecture, and astronomy. He concludes that geometry is indispensable to society and …

General Steps In The Evolution Of The Calculus From The Time Of The Ancients To The Present, Sister Mary Virginia Ssf Jul 1931

General Steps In The Evolution Of The Calculus From The Time Of The Ancients To The Present, Sister Mary Virginia Ssf

Electronic Theses and Dissertations

This thesis, submitted to Xavier University in partial fulfillment of requirements for a Bachelor of Science degree in 1931, traces the historical development of the calculus from ancient Greek mathematics through the early twentieth century. The study is organized chronologically across eight sections. The introduction defines key mathematical terms including calculus, variable, and limit, and situates the calculus as the most powerful instrument of mathematical investigation. The thesis then examines the Method of Exhaustion developed by Greek mathematicians including Antiphon (430 B.C.), Eudoxus (370 B.C.), and Archimedes (225 B.C.), whose summation of infinite series represents the nearest ancient approach to …


The Alkaloids, Felix F. Barre Jul 1931

The Alkaloids, Felix F. Barre

Electronic Theses and Dissertations

This thesis, presented for the degree of Bachelor of Science, provides a systematic chemical study of the alkaloids, a class of complex nitrogenous plant substances possessing basic properties. Barre opens by defining the alkaloids and surveying the various systems used to classify them, whether by natural versus artificial origin, chemical nucleus (pyridine, quinoline, or isoquinoline), volatility, or botanical family of origin, and outlines their general physical and chemical properties, including solubility, optical activity, and characteristic reactions with precipitating and color-test reagents.

The thesis details standard laboratory methods for the extraction and separation of alkaloids from plant material, including a step-by-step …

The Development Of Colloid Chemistry, Oscar A. Bouise Jun 1930

The Development Of Colloid Chemistry, Oscar A. Bouise

Electronic Theses and Dissertations

At first, it was a blur, that had shrouded a great mystery for ages and ages, until some seventy odd years ago. Then came Thomas Graham, who could not satisfy himself with merely viewing a blur as a blur. Being a scientist, he applied his mind experimentally, with the keen precision of any of the eminent astronomers using a telescope, and viewed more clearly this mist which hovered above the horizon . But maybe it was not due time fir the unfolding of the great secret, for Graham's focus only revealed a more complicated mist that had been seen before. …

History Of Applied Geometry, Evelyn Jackson Jan 1930

History Of Applied Geometry, Evelyn Jackson

Electronic Theses and Dissertations

Mathematics: Just what does the word mean to us? After a moment of thought many different meanings may present themselves to our minds. At first we are inclined to say that the word mathematics covers a vast field. We are justified in so thinking because mathematics embraces a wide scope of study. Were we to say that it is a science we should place it in its proper genius, for it is truly a science of numbers and space. However, could not the science be the art of calculation or the art of computation?

Scholasticism An Intellectual Basis And Unifying Principle Of Modern Science, Alice Veronica Johnson Jan 1929

Scholasticism An Intellectual Basis And Unifying Principle Of Modern Science, Alice Veronica Johnson

Electronic Theses and Dissertations

This thesis, completed at Xavier University of Louisiana in 1929, argues that Scholastic philosophy, and the thought of St. Thomas Aquinas in particular, supplies an intellectual foundation that unifies the findings of modern science. Johnson takes up the common charge that Scholasticism is a barrier to scientific progress. She contends instead that it is the one philosophy able to answer the ultimate questions of “whence” and “how” that science cannot address on its own.

Johnson tests this claim against several fields in turn: astronomy, geology, physics, chemistry, and psychology. In astronomy, she reviews competing theories of the origin of the …


Color., Bruce B. Vance Jan 1928

Color., Bruce B. Vance

Electronic Theses and Dissertations

Color, any attempt to apply the scientific principles of color vision in the making of a picture must surely fail if it be not granted at the out set that it is only to a limited degree that those principles can apply. Color appreciation is as much a psychical as a physiological, and indeed, it is psychical not only with regard to the objective impression itself, but also with regard to the subjective, the associational mental process. Previous knowledge and training, experience traditions, the association of color impressions with impressions previously received through other senses and stored away as memories, …
