Are You Educated?, H. Earl Rath Jan 1932

Are You Educated?, H. Earl Rath

Science Bulletin

A few months ago we tried to set up a sort of standard by which a per- son might judge as to whether or not he could satisfy the demands of ordinary health. It shall be the purpose of this article to set up a standard by which an individual might judge of the adequacy of his or her health knowledge. This discussion is based largely on the "Ten Commandments" by Dr. Livingstone Farr -and, given in an address before the American Public Health Association, and printed in College Text books of Hygiene by Smiley and Gould. Many will probably …

Current Induction, L. Begeman Jan 1932

Current Induction, L. Begeman

Science Bulletin

The modern transformer, now quite generally used in the commercial distribution of electrical power in the cities of the world, ranks next to the dynamo in importance in the electrical world. The transformer is an invention which embodies. the practical application of Faraday's first experiment in current induction, in which a closed iron ring carrying a primary coil and a secondary coil was used.

National Geography Meetings, Alison E. Aitchison Jan 1932

National Geography Meetings, Alison E. Aitchison

Science Bulletin

The Christmas vacation always brings a full quota of meetings of interest to those who are engaged in educational work. Especially does this seem true for those interested in science. Two meetings of value to geographers were held at Ypsilanti, Michigan, where the new Union building, an alumni project of the Michigan State Normal College, afforded an excellent meeting place.


The Lure Of The Turtle, Roy L. Abbott Jan 1932

The Lure Of The Turtle, Roy L. Abbott

Science Bulletin

I believe I never meet with a turtle without looking at him a second time at least, and I usually pick him up if I have an opportunity. For there is a lure about him, he attracts me powerfully though I can not tell just why. It may be partly admiration for his mighty ancestry, partly pity for his fallen estate, but some of it is just plain, everyday liking for his rather unprepossessing self. But there is plenty to see in him for all that!

Disillusionment!: Editorial Dec 1931

Disillusionment!: Editorial

Science Bulletin

Who has not felt his very flesh writhe and shrink on reading Hugo's fearful story of Gilliatt's fight with the octopus? The art of the great Frenchman is here superb. He compels the reader to identify himself with his hero. Gilliatt's struggles and emotions are his also. The monster projects itself upon him- its tentacles entwine him, their horrible sucking vacuum cups pull at his flesh; he strains, heaves, grasps at these accursed circling gelatinous bands; they seem to yield, but never actually; they crush, excoriate, scarify - his flesh seems to melt - he is disintegrating-it is death in …

On Snakes Swallowing Their Young, Roy L. Abbott Dec 1931

On Snakes Swallowing Their Young, Roy L. Abbott

Science Bulletin

Do snakes actually swallow their young to protect them and later spew them out again as Dr. Ball states further in his article? Well, I have never seen them do this, and I do not know of any other student of snakes who has. Ditmars, Curator of Reptiles at the New York Zoological Gardens, has never seen anything of this kind, and he daily observes more snakes than the average man does in a lifetime.


General Science, E. J. Cable Dec 1931

General Science, E. J. Cable

Science Bulletin

In our last article we discussed one of the common minerals found on the earth's surface. In this article the writer will attempt two things: first, to describe a few of the common rock-making minerals; and second, to discuss some of the simple ways of distinguishing the common igneous rock found on the earth's surface. The commonest igneous rock-making minerals, besides quartz, are the feldspars, the irons, pyroxene, hornblende, and the micas.


Current Induction, L. Begeman Dec 1931

Current Induction, L. Begeman

Science Bulletin

ln the last number of the Science Bulletin [vol.4 no.3] we discussed Faraday's two experiments in current induction. It is interesting to recall at this time that September 21 of this year a centennial celebration of Faraday's discovery was held in Queen's Hall, London. Sir William Bragg, a renowned English physicist, gave the address on this occasion. This address was broadcast generally in America, being transmitted across the ocean by radio.


What About Organic Evolution?, C. W. Lantz Dec 1931

What About Organic Evolution?, C. W. Lantz

Science Bulletin

One of the great generalizations of science is the theory of organic evolution. It is, however, very commonly misunderstood by the average person. To many, thanks to such deluded individuals as the late Wiliiam Jennings Bryan, it is a very dangerous doctrine and any one who believes in it is an atheist and must reject the teachings of the Bible. I have had college students ask this question. Is it possible for one to believe in evolution and be a Christian? This question arises only from one who has misconceptions as to the real meaning of evolution and perhaps also …


Snakes That Do Not Exist, C. W. Lantz Dec 1931

Snakes That Do Not Exist, C. W. Lantz

Science Bulletin

As a boy I was always on the lookout for two kinds of snakes which I never found. These were the so- called hoop snake, and joint snake. According to popular tradition - and the tradition is still with us - the hoop snake was supposed to take his tail into his mouth and go rolling about the country much to the amazement and horror of his human observers.


Motivation In Physics, W. H. Kadesch Dec 1931

Motivation In Physics, W. H. Kadesch

Science Bulletin

In recent years there has been a decided trend in high schools the country over toward general science, and away from the particular sciences, physics, chemistry, biology, etc. The proponents of general science seem convinced that this is due to a better choice of subject matter in their field, and to better methods of presentation. However this may be, it will certainly be well for those of us who have to do with the teaching of the special sciences to subject our own work to critical examination. We should aim to discover our faults of whatever kind, and eliminate them.

David Starr Jordan: Editorial Nov 1931

David Starr Jordan: Editorial

Science Bulletin

The subject of this sketch seems to have been fortunate in both conditions, heredity and environment. He developed a huge, vigorous body and a powerful, alert mind, one peculiarly capable of noting and retaining infinite details of color, form, and structure. The fishes, a group characterized by almost unbelievable diversity of form, color-pattern, and habitat, were thus admirably suited to his retentive type of mind, and David Starr Jordan became an ichthyologist, a student of fishes.


Are You Healthy?, H. Earl Rath Nov 1931

Are You Healthy?, H. Earl Rath

Science Bulletin

Most authors of texts on hygiene have presented some sort of an ideal towards which each individual should aim. All of them have merit, but the present article is based largely (with a few modifications) on the eight points of "The Health Ideal" as set forth in the "College Text Book of Hygiene" by Smiley and Gould.

Induced Current Electricity, L. Begeman Nov 1931

Induced Current Electricity, L. Begeman

Science Bulletin

In the May Number of the Science Bulletin, the writer gave a brief outline of the historical development of our present knowledge of the magnetic properties of an electric current. In tracing this development from an experimental point of view, a brief statement was made of the contributions of each of the following renowned scientists: Oersted, Arago, Ampere, Faraday and Henry. In this article of the May Number no reference was made to current induction as one of the magnetic effects of an electric current.


Suggestions For The Teaching Collection In Biology, O. R. Clark Nov 1931

Suggestions For The Teaching Collection In Biology, O. R. Clark

Science Bulletin

There is nothing in the Biology course which can take the place of carefully planned and directed field work. The students should be encouraged to observe carefully and accurately for themselves and be given every opportunity to become acquainted with living things in their natural surroundings. The aquarium and terrarium can be made to supply much interesting material for study and should be in the laboratory whenever possible.


The Toll Of The Automobile, Roy L. Abbott Nov 1931

The Toll Of The Automobile, Roy L. Abbott

Science Bulletin

When the telegraph first came into general use in this country thousands of birds, particularly prairie chickens, were killed annually as a result of flying against the tightly stretched wires. On account of its great height, many birds collide with the Washington Monument, and are thus fatally injured; every lighthouse along the coast takes a great toll of birds during the year. The railroads destroy many animals also, but the automobile murders more wild animals than all the above-mentioned things combined. In the destruction of our wild fauna, it is next in importance to the rifle and shotgun. The Isaac …


Phantom Ringnecks, Roy L. Abbott Nov 1931

Phantom Ringnecks, Roy L. Abbott

Science Bulletin

Now the ring-necked pheasant is a big bird; he is about the size of a well-fledged leghorn rooster, weighs perhaps three and one-half to four pounds, and, including his long tail feathers, stretches easily two feet or more in length. Moreover, Nature fairly outdid herself in beautifying the ringneck; he is a perfectly amazing combination of green and red, of white and gold and bronze. His mate, on the other hand, is about the color of a prairie chicken, severely plain, modest and retiring.
