Boy Chemist “Eats Up” Course in Foodstuffs (Dec, 1938)

Boy Chemist “Eats Up” Course in Foodstuffs

Relationship between the fields of chemistry and cookery is the research project that interests seventeen-year-old Edgar Friedenberg, the youngest man ever to appear on a program of the American Chemical Society. Friedenberg is pictured below taking time off from his studies in synthetic foodstuffs to try a little practical work with the frying pan.

How the Ice Age May Return

By Gaylord Johnson

WHEN we speak of the glacial period, or ice age, we are apt to think of it as over and done with for good—as unlikely to return on earth as the prehistoric dinosaur. When we see scratched and. grooved rocks showing the terrific grinding power of the mile-thick ice sheet that once covered the northern part of our temperate zone, we never think of what might happen to New York, Chicago, Boston, Leningrad, London, and all our other northern cities, if the conditions should return which produced the age of ice in the Northern Hemisphere.

Experiments With Oxygen FOR THE AMATEUR CHEMIST (Nov, 1936)

Experiments With Oxygen FOR THE AMATEUR CHEMIST

A few common chemicals supplied by the druggist and simple apparatus is all that is required to produce these interesting experiments with oxygen.

by VERNON TRACEY

OXYGEN experiments form a very interesting field of adventure for the amateur chemist due to the fact that oxygen is one of the most active of the chemical elements. It readily combines with most any other element to form many different compounds. These compounds of oxygen and other elements are known as “oxides” and the process of combination is called “oxidation,” or more commonly known as burning. We see examples of oxidation every day in the burning of fuel, but this is not very active when one considers the fact that the air is only one-fifth oxygen, the rest being mainly nitrogen and a small percentage of other gases.

WE GOT OUR FACE FROM A FISH (Jul, 1931)

WE GOT OUR FACE FROM A FISH

Nothing else is of such supreme interest as the gripping and vital story of “Life— The World’s Greatest Mystery.” Here is the second installment of the dramatic history of man’s rise from a mass of floating jelly to the human being he now is. In a most striking manner a famous authority details the amazing facts about the molding of the human face.

What They Talked About: LAST month, Dr. William K. Gregory, world-famous scientist of the American Museum of Natural History, told Michel Mok, staff writer, how the earth and life originated. About two billion years ago the earth was torn out of the sun by the passing of another star. Slowly it condensed and cooled down. A billion years later, chemical forces created tiny bits of living jelly in the primeval puddles.

New Discoveries Show Electricity Governs Our Lives (Feb, 1934)

New Discoveries Show Electricity Governs Our Lives

By Edwin Teale

EXPLORERS, working in one of the strangest realms of science, are unearthing curious, dramatic facts. The way autos run, the way seeds sprout, the way eggs hatch, the way radios function, and even the way we feel when we get up in the morning, the latest tests have shown, are affected by flowing, invisible charges of electric power. Recently, experiments in the laboratories of many lands have added to our knowledge of the magical work of electricity in the air.

LIFE from the Test Tube (Jun, 1936)

LIFE from the Test Tube PROMISED BY NEW FEATS OF MODERN ALCHEMISTS

By Robert E. Martin

FOOD from the test tube, strange acids that conquer disease, complex chemicals that make up the vital ingredients of human flesh and blood—these are recent creations of pioneers in a fascinating, unexplored realm of chemistry, far afield from the normal and conventional affairs of workaday laboratories.

Like seekers of another age, hunting an “elixir of life,” these modern alchemists are brewing odorous broths from tons of fish and bales of vegetables in order to extract and study the raw materials of living things. With their new-found knowledge, they are succeeding in putting together extraordinary substances that only nature knew how to produce before. Nearer and nearer they are coming every day to penetrating the age-old mystery of life.

Dangerous ACIDS MADE SAFELY BY Home Chemist

By Raymond B. Wailes

BECAUSE they enter into a wide variety of reactions, acids form an interesting and important group of chemicals. By preparing them in small quantities, the home experimenter can learn a great deal about chemistry and its many mysterious reactions and valuable processes.

How Scientists Are Taking the Pinch Out of America’s Billion-Dollar Shoe Bill

New Tanning Discoveries Will Bring You Cheaper Footwear By John Walker Harrington

WELL-SHOD feet are among the essentials of health and long life,” declared Dr. John B. Huber in a recent article in POPULAR SCIENCE Monthly.

The magnitude of our national shoe bill is revealed in this story of new discoveries in tanning, which hold forth hope of a coming fall in every family’s expenses for footwear.

Are X-Rays Outclassed by Powerful New “Odic Ray”? (Mar, 1922)

Are X-Rays Outclassed by Powerful New “Odic Ray”?

DISCOVERY of “odic rays” of high penetration produced simply by the electric current drawn from an ordinary light socket, and yet with the curative and medicinal value of X-rays, is claimed by Dr. Edgar L. Hollingshead, of Pasadena, Calif.

With simple, inexpensive apparatus he is reported to have passed rays through 11-1/2 inches of lead and 4-1/2 inches of steel, at such strength as to sear dental X-ray films encased in tinfoil.

Amuse Friends with CHEMICAL Stunts (Apr, 1934)

Amuse Friends with CHEMICAL Stunts

DO YOU like to dabble with chemicals? It was a hobby with Thomas A. Edison during his youth and formed the basis of an education that later brought thousands of new inventions into the world. Far from being a “dry” science, chemistry can be very amusing and entertaining. How many people would believe that you could pour a little drinking water into a china bowl and cause it to burst forth with flames several feet high—without the use of matches?
