Historical Forces Shaping Americans' Perceptions Of Wildlife And Human-Wildlife Conflicts, Michael R. Conover, Denise O. Conover

Wildlife Damage Management Conference

From colonial times until the 19th century, the dominant American view of wildlife and its management was dualistic—wildlife species were divided into good animals (those which had commercial value or could be eaten) or bad animals (those which threatened the colonists’ safety or food supply). Philosophically, early colonial Americans believed that the environment was to be manipulated for man’s purposes. Under the impact of modernization, Darwinian influence, over-exploitation of resources, and environmentally-conscious professionals, Americans in the late 19th century began to appreciate the recreational value of wildlife and to develop a more protective attitude toward it. Still the dichotomy between …

Solomon's Sea And The Biblical Π, Andrew Simoson

ACMS Conference Proceedings 1997

From I Kings 7:23, the apparent diameter and circumference of a circular ring are given as 10 and 30 cubits which suggests that the Biblical value of π is 3 rather a number closer to π. However we recount seven different somewhat whimsical explanations as to why this conclusion is overly-hasty.

Mathematics And Values: Can Philosophy Guide Projects?, Michael H. Veatch

ACMS Conference Proceedings 1997

The philosophy of mathematics has provided insight on questions of foundations and mathematical truth; however, it has not been very fruitful in guiding the practice of mathematics. This paper attempts to find points of contact between a Christian worldview and the choice of mathematical projects and methods. Three areas are considered: (i) dubitability in current research, (ii) the intrinsic value of contemporary mathematics to contemporary society, and (iii) the affirmation of human value in the use of mathematics. Finally, a framework for valuing mathematics is proposed as an encouragement to think more deeply about how a Christian might choose a …

The Mathematical Sciences And The Mediator Of Creation, W. David Laverell

ACMS Conference Proceedings 1997

This article stems from a conviction that while the development of a theistic view of the mathematical sciences is a laudable goal and much to be encouraged, it is incumbent upon us to explore every avenue that might lead to a distinctively Christian perspective. This leads naturally to a consideration of the unique role played by Christ in Creation, and a convenient framework is provided by seeing Christ as Mediator of Creation. We shall discuss the term itself, examine the biblical passages that seem to present the concept, consider the ways these passages have been understood by theologians, and …

Digital Filtering And Smoothing: A Student Simulation Project, Eric Gossett

ACMS Conference Proceedings 1997

A bug tracking problem is used to introduce students to filtering and smoothing real-time data. A predictor-corrector filter/smoother algorithm is developed and a simulation platform is provided so that students can program and test implementations of the filter/smoother. The platform includes the ability to animate the simulation.

The tracking problem: A small computer bug is traveling around the $x-y$ plane trying to avoid detection. We can eliminate the bug if we can produce a reasonably accurate approximation to its trajectory.

We have a bug detecting device which can be pointed at the plane. It can measure the $x$ and $y$ …

Mathematics At Chartres Cathedral, Richard Stout

ACMS Conference Proceedings 1997

Having had several opportunities to travel to France, often with groups of students, our trips have usually included a visit to Chartres, especially to visit the magnificent Gothic cathedral that dominates the town. On a recent visit I was again struck by the beauty, majesty and awe that the cathedral inspires. The building not only does a remarkable job of telling Biblical stories and of enclosing a space conducive to worship, it directs one's eyes and one's spirits upward. This is achieved not only by the beautiful stained glass windows and the striking sculptures, but also by the overall design …

An Investigation Of The Behavior Of Calculus Students Working Collaboratively In An Interactive Software Environment, Angela Hare

ACMS Conference Proceedings 1997

Recent work in the area of cognitive research in mathematics education focuses on detailed examinations of the learning process of students and how this process is affected by current innovations in the classroom, including collaborative learning and the use of computers and interactive software. Much of this work is supported by the learning framework of constructivism, a school of thought which is based on the work and writings of Jean Piaget. Piaget, a French psychologist in the mid-twentieth century, observed the learning behavior of children and concluded that individuals construct their own knowledge by creating mental structures which explain their …

Using Java And Html For Linear Algebra Instruction, Jonathan R. Senning

ACMS Conference Proceedings 1997

This paper addresses some of the issues involved with using the HTML, JavaScript and Java to develop and serve a sequence of laboratory modules for use in teaching linear algebra. Attention is paid to the rationale for this approach as opposed to the more traditional approach of laboratory exercises executed using MATLAB or some similar computational tool. Several methods to display mathematics with HTML are described. Some implementation detail and a brief description of the HTML and Java based Linear Algebra Visualization Assistant (LAVA) is presented.

Fractal Geometry And Chaos Theory: From Old Problems To New Models And Methods, Terence H. Perciante

ACMS Conference Proceedings 1997

Fractal geometry and chaos theory are deeply rooted in significant problems in the history of mathematics and science. While mathematicians have geometrical descriptions of space with its properties, scientists have attempted to characterize the physical properties of fundamental entities present in space and time. The separate investigations frequently influenced each other and led to profound theories, answers, and models. However, at the same time new problems repeatedly arose internal to mathematics and externally in the applications to which mathematics was applied. Fractal geometry issues from these antecedents in response to features and processes in nature not easily represented by historical …

Was Newton's Calculus A Dead End? The Continental Influence Of Maclaurin's Treatise Of Fluxions, Judith V. Grabiner

Pitzer Faculty Publications and Research

We will show that Maclaurin's Treatise of Fluxions did develop important ideas and techniques and that it did influence the mainstream of mathematics. The Newtonian tradition in calculus did not come to an end in Maclaurin's Britain. Instead, Maclaurin's Treatise served to transmit Newtonian ideas in calculus, improved and expanded, to the Continent. We will look at what these ideas were, what Maclaurin did with them, and what happened to this work afterwards. Then, we will ask what by then should be an interesting question: why has Maclaurin's role been so consistently underrated? Thse questions will involve general matters of …

JOHN WgW Volume 7, Number 2 NEW MUIR Spring 1997 X I 4 J^,AN EPISODE IN THE YOSEMITE: by Frank E. Buske copyright @ 1989,1991, by Frank E. Buske (Editor's note: Dr. Frank Buske, emeritus professor and former Chair of the English Department at the University of Alaska, Fairbanks, now lives in Tucson, Arizona. This paper was presented at the 1990 John Muir Conference at UOP, and is published here, along with letters from a private collection, with the author's permission.) ('•< Muir spent the winter of 1873-75 at the McChesney home in land, having come down from his beloved mountains to spend time putting into words some of the observations he had made • ■ nig the trees and the glaciers and on the ■ - les. Mrs. Jeanne Carr and others of his I «ls had, for a long time, been * •imaging him to do more writing; they HHgested that there was a market for his j I les and a need for him to set down his ilf|overies while they were still fresh in his mind. Mrs. McChesney, in a later reminiscence, described Muir as "dressed gi»iei ally in what we call now negligee, i.e., he wore a blue flannel shirt, but was never : without a sprig of some green plant as an-S*0 jjpment." Muir's apparel would be appropriate for ij§krnd of life he most enjoyed. He disliked lifting to dress for any formal occasion and hied to avoid any social gathering that would HHuire clothing and behavior that were not comfortable to him. Although he had uently written of his loneliness, sped1 w.f t enviously about his relatives and ids who had married and were raising families, he seems to made no effort to alter his own bachelor status during that Winter in the Bay Area. Mrs. J "• ' Carr The subject of John Muir and his relationship with women is interesting to ponder, and is a topic that has received a good deal of attention and even more misinformed speculation. Some verses that he wrote before this time, highly critical of young women, their appearance and the way they dressed, prompted his friend, Bradley Brown, to write the eighteen-year old Muir, "Excuse me, John, but perhaps unreciprocated love was the cause of your rhyming against the sweet little creatures. To love is painful, that is true. Not to love is painful, too. But oh! It gives the greatest pain to love and not to be loved again." The subject of Muir's poem may well have been imaginary but Brown's observations can certainly be considered prescient. At twenty-two, in Prairie du Chien, Wisconsin, working with ice-boat inventor Wiard, John Muir wrote his brother, David, telling him of the people he was meeting. David, very much a ladies' man, replied, "I would like very well to hear that piano and Miss E.P. (excuse me, John) playing on it." Miss E.P. was, of course, Emily Pelton, niece of the proprietors of the Mandell House where Muir was living. In December of that same year, John Muir wrote his sister, Sarah, and her husband, David Galloway, of an occasion which shows a rather vivid picture of his social skills: UNIVERSITY OR page 1 (continued on page 3) PACIFIC
