Mutual Induction And The Internal Resistance Of A Voltaic Cell, L. Begeman

Proceedings of the Iowa Academy of Science

The usual method of making a rapid determination of the internal resistance of a voltiac cell, primary or secondary, is by means of the condenser in circuit with a ballistic galvanometer. The deflection of the galvanometer due to the discharge of the condenser is first taken on open circuit with the cell and again when the cell is on a closed circuit the known resistance. The working formula is r=d—d¹ over d¹xR, in which d and d¹ are the different deflections of the galvanometer needle and R is the external resistance of the closed circuit. The …

Municipal Hygiene - Part Ii - Milk, C. O. Bates

Proceedings of the Iowa Academy of Science

It is the purpose of this paper to help popularize the scientific facts that have been discovered by the research laboratories which are controlled and fostered by our national government and individual States of the Union, and by the laboratories of the denominational institutions of higher education. Vast sums of money are spent each year to maintain such work. No one can question their efficiency or practical value. Such knowledge is not prized as highly as it should be, nor are the discoveries as thoroughly known as they should be. The bulletins that are issued from the various stations are …

Variation In Ray Flowers Of Anthemis Cotula And Other Composites, H. S. Fawcett

Proceedings of the Iowa Academy of Science

The object of this study was to determine the amount of variation occurring in the number of ray flowers of the Mayweed (Anthemis cotula L.), to compare the variations occurring in different localities, and also the variations in different plants of the same locality, and finally to compare this variation with that of a few other species of Compositae.

J. J. Thomson's Theory Of Matter, L. Begeman

Proceedings of the Iowa Academy of Science

J. J. Thomson's theory of matter is largely the outgrowth of his own experimental researches in the nature and structure of electricity. In reading the records of his work it is often hard to discriminate in just what sense he uses the term "electricity." It is certainly not well defined whether the term stands for primordial energy or matter.

Presidential Address - The Relation Of Physics To The Other Material Sciences, A. A. Veblen

Proceedings of the Iowa Academy of Science

The last year or two of the nineteenth century and this first year of the twentieth have been prolific in literature dealing in one way or another with science topics. There have been addresses before learned and educational gatherings, articles in science journals, and in periodicals of well-nigh all kinds, much of all this writing having been produced by the masters and leaders of science; and the object of these productions has been, generally, to give a view of the present condition and importance of scientific work and knowledge, or to review recent progress either of science in general or …

A Ruling Engine For Making Zone Plates, W. M. Boehm

Proceedings of the Iowa Academy of Science

About a century ago the corpuscular theory of light was falling into disfavor among scientific men in general and the wave theory was taking its place. Among the many contributions to the subject we find the writings of Fresnel. It was he especially who struck the decisive blow at the dying hypothesis. That part of his work which is of particular interest to us is his application of Huyghen's principle to phenomena of diffraction.
