Remarkable Remarks: Editorial

Science Bulletin

In a recent book, "The Mysterious Universe," the author, Sir James Jeans, says that "the total number of stars in the universe is probably something like the total number of grains of sand on all the seashores of the world." In another book of his, "The Stars in Their Courses," published about the same time, he repeats the above statement and adds: "or to take another comparison, the total number of stars in the universe is probably about equal to the number of drops of rain which fall on the whole of London in a day of heavy rain."

Caves, O. B. Read

Science Bulletin

Man's interest in caves dates back perhaps to prehistoric times. He probably used them as homes in his very earliest history. It is in caves that we find bones believed to be of primitive man. As he became civilized he developed and prepared for himself houses to live in and his interest in caves has taken on an entirely different aspect. They have become a source of curiosity or a field for scientific study.

The Junior Academy Of Science

Science Bulletin

This section of the Science Bulletin is devoted to High School Science Clubs of Iowa who are organizing the Junior Academy of Science of Iowa. This organization is to give the clubs affiliating the advantages that can come from a state organization. Its success depends upon the response of the high school clubs themselves. It is to be your organization and this section of the Bulletin is to serve as a means for the exchange of ideas between clubs and to give suggestions as to aids and helps for programs. Contributions from clubs are desired.

The State Meeting Of The Junior Academy

Science Bulletin

The first meeting of our organization will be held at Teachers College, Cedar Falls, in connection with the annual meeting of the Iowa Academy of Science on April 29 and 30 [1932]. The chapters of the Cedar Falls High School and Teachers College High School will be hosts.

National News Of High School Science Clubs

Science Bulletin

At the recent meeting of the American Association for the Advancement of Science in New Orleans, Dr. Otis W. Caldwell of Columbia University reported before the Academy Conference on the work of science clubs in different states.

Suggestions For Biology Or Nature Clubs, Ross W. Harris

Science Bulletin

The very first requirement for a successful club of this nature is enthusiasm for and an interest in the. world of living things. The sparks for kindling enthusiasm must come from off the hearth of the sponsor. While the students must be guided they should be led to feel that it is their program that they are working out and not that of a teacher who grants credit for participation.

The Use Of Posters In Club Work

Science Bulletin

Posters furnish excellent illustrative material for club programs and will add much interest to the work. There are usually members of the club who have artistic ability and can make use of their ability in this way, but it is not necessary to be an artist in order to make good posters or cartoons, as excellent results can be obtained by cutting advertisements from magazines and arranging them and pasting them on cardboard so as to illustrate various subjects. The value of the poster does not depend upon its artistic side but in the clever representation and emphasis of some …

A Successful Club Project In Biology

Science Bulletin

A few years ago when the author was teaching biology in a suburban high school of Chicago, the tussock moth became a menace to the shade trees in that vicinity. The biology students took up the problem of the tussock moth and how to eradicate it. The life history and habits of the moth were studied. Collections were made to show the life history. The Commercial Club became interested and a talk on the moth was given by a club member at one of their meetings.

The following are suggested projects in biology. Next month the issue will be devoted to physics and chemistry.

Two Fundamental Equations Of Current Electricity, L. Begeman

Science Bulletin

Formulas in physics are mathematical expressions of natural laws or principals well established. The two most important for the ordinary citizen are first the one that gives expression to Ohm's law and second, the one that shows how to calculate the power of a current.

To The Members Of The Junior Academy, Joseph C. Gilman

Science Bulletin

The purpose of the Iowa Academy of Science is to aid in the advancement of science throughout the state. When the American Association for the Advancement of Science suggested that the state academies sponsor a movement among high school science clubs to organize into statewide units, the Iowa Academy welcomed the opportunity offered by this situation to serve science.

The Inert Gases, R. W. Getchell

Science Bulletin

Nitrogen gas is lazy. A chemical revolution may enlist and lead away nearly every other element and compound in the air, but nitrogen will stay at home and refuse to become excited. Less than forty years ago, Lord Rayleigh in England made use of this characteristic by removing the other components of the air and collecting the remaining supposedly pure nitrogen in order to study it.

The Apology Of A Pedagogue: Editorial

Science Bulletin

"The world's stock of knowledge is seldom augmented by pedagogues." H. L. Mencken.

With all due respect to the author of the above and the several brilliant things he has written, bosh! The sentence makes interesting reading, and doubtless returned the writer several cents per word, besides giving his doting henchmen many chuckles at the expense of the puerile pedagogue. But mere pertness of expression connotes neither truth nor profundity, and had the writer of the above sentence set about deliberately to formulate a fundamental untruth, he could not have fashioned one whose Munchausen quality was more obtrusively obvious.

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

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

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

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!
