Instinct Or Intelligence In The Great Golden Digger?, Roy L. Abbott

Proceedings of the Iowa Academy of Science

"

To know everything and to know nothing according as it acts under normal or exceptional conditions: that is the strange antithesis presented by the insect race." So said that profound student of insects, Fabre, after an immense amount of experimentation. No one has written so entertainingly about insects as has this great Frenchman; few have equaled and none excelled him in the wealth and variety of his observations upon them. But he was trained as a physicist and a mathematician and consequently, brought into his biological studies the viewpoint of the inorganic sciences.

Some Recent Contributions To Our Understanding Of Corn Diseases, I. E. Melhus

Proceedings of the Iowa Academy of Science

There is probably no other disease problem of greater significance economically than that of corn. Hence, the purpose of this paper is to sketch briefly the progress that has been made in this study and to point, in a general way, to some phases of the problem that are immediately before us. Because of its complexity and the misconception as to its significance, a beginning in this field was tardy. Our method of attack on the corn problem seems to be passing through the characteristic successive stages of investigation. These stages may be traced as beginning with observation of the …

Resolutions On Darwin, T. H. Macbride, L. H. Pammel

Proceedings of the Iowa Academy of Science

It is fitting that the Iowa Academy of Science should, in some way, spread on the minutes of its proceedings, its estimate of what science owes to the work of Charles Darwin, the centenary of whose birth occurred on the 12th of February, 1909. Darwin's contribution to science was two-fold: in the first place it consisted of additions, the result of research, additions made directly to the body of the knowledge of his time: secondly, it consisted in a singular impulse to natural history study, an impulse destined to be long-lasting as science itself.

Some Diseases Of Rocky Mountain Plants, L. H. Pammel

Proceedings of the Iowa Academy of Science

Only a very small beginning has been made of the study of the parasitic fungi of the Rocky Mountain Region. A large number of interesting parasitic diseases affecting the cultivated plants, trees and shrubs, as well as herbaceous plants, occur in the Rocky Mountain region. The diseases that I have discussed constitute only a small part of those occurring here.

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 …

Annual Address Of The President - Needed Changes In Scientific Methods, H. W. Norris

Proceedings of the Iowa Academy of Science

We live in a period that sees wonderful attainments in science and art, so that in theory and practice many think the summum bonum has been reached. It is pre-eminently the age of science and the application of scientific methods to all phases of human activity. The forces of nature have been made subject to the will of man. The relations of man to his surroundings have been carefully considered. The province of human intellect has been made the ground of scientific investigations. We now see scientific methods foremost and uppermost, and all human thought is more or less permeated …

Bacteria, Their Relation To Modern Medicine, The Arts And Industries, L. H. Pammel

Proceedings of the Iowa Academy of Science

It has been customary for the president in making his retiring address, to choose some popular subject and discuss it on broad lines. In some cases my predecessors have given a resume of the scientific literature in our own State, and I need not say that we all feel proud of the work accomplished by this small band of workers. I shall venture, in this address, to discuss the subject of Bacteria along general lines and hope I may be able to correct some popular misapprehensions concerning the subject.
