Chemical Experiments with Chlorine (Jan, 1934)

Chemical Experiments with Chlorine

• A VERY interesting series of experiments may be carried out with chlorine, in the formation of both organic and inorganic compounds of a wide range of application.

The Magic of Sound Explained By Science (Feb, 1930)

The Magic of Sound Explained By Science

The laws of nature which enabled Biblical trumpets to shatter the walls of Jericho are explained in this article. On a smaller scale you can perform the same historical feat with ordinary water tumblers.

By SAM BROWN

HE WAS very grave in his demonstrations. He exhibited a delicate goblet of thinnest glass. He struck the glass sharply with his finger so that it sang out with a low, musical note.

Mystifying With Chemical Magic (Sep, 1936)

I like how it states that all of the stunts are harmless then proceeds to explain all the ways the ingredients are not.

Mystifying With Chemical Magic

WHILE all stunts described above are harmless, care should be exercised in the handling of the phosphorous and sulphuric acid (H2S04). Phosphorous when exposed to open air for periods longer than two minutes will burst into flame, therefore submerge it in kerosene when not in use. To protect your fingers from its effects powder them with chalk or talcum. A pair of small forceps may be also used, if available, in handling small pieces of the chemical. In handling the sulphuric acid be sure that none drops on clothing as it rots material.

Glimpses of of Men in the Public Eye (May, 1929)

Glimpses of of Men in the Public Eye

WHEN, a little more than ten years ago, Edward R. Armstrong first propounded his idea of building a series of great floating airdromes and anchoring them at intervals across the Atlantic to provide way stations for a regular flying service between America and Europe, the public regarded it as a fantastic dream. Aviation experts took the idea more seriously. Armstrong’s words, as consulting engineer in charge of mechanical and chemical experimental development for the Du Pont company, carried authority. Still, realization of the project was considered a thing of the dim future.

Experts Pick 1951′s Biggest Science News (Dec, 1951)

Cortisone addiction is no allegory.  The movie of Bigger Than Life was based on a 1955 New Yorker article titled “Ten Feet Tall” written by Berton Roueché who also wrote the 1980 book Medical Detectives which became one of the inspirations for the House TV series.

Experts Pick 1951′s Biggest Science News

What was the biggest news from the laboratories and workshops of the scientists this year?

If you were to ask 10 of America’s best-known science reporters—as Popular Science has done—you would get 10 different answers to this question.

The 10 journalists to whom the question was put are pictured below. All of them are members of the National Association of Science Writers. They cover science news the way Washington correspondents cover politics and police reporters cover crime. They have spent the past year interviewing scientists, attending scientific meetings and studying scientific reports to obtain the news of science for the readers of the newspapers, press associations and magazines that they represent. The stories that they consider this year’s biggest news are summarized in the article that follows.

make your own BUBBLE COMPOUND (May, 1950)

Glim was a brand of dish washing soap

make your own BUBBLE COMPOUND

WITH a startling new formula worked out particularly for MI readers, you can produce rainbow-colored bubbles that last longer and are more brilliant than the old-fashioned kind made with a soap base. In addition to the natural rainbow coloring, it is practical to add luminous powder to the new formula so that the bubbles will glow when produced in the dark.

SCIENCE NEWS of the MONTH (Feb, 1936)

What is down hill to a continent?

SCIENCE NEWS of the MONTH

Continents Have Stopped Sliding Down Hill
• THE migration of continents, which some geologists think a continual process, while others deny it, is suggested by George W. Munro, of Purdue University, in a letter to Science, to have been an actual occurrence; but one which has happened only twice in two billions years of the earth’s history, when sufficient heat was developed near the surface to start continental masses moving under pressure. He suggests that the American continent hit a snag, which broke its backbone.

Braving the INFERNO of a VOLCANO (Aug, 1933)

Sure, they say they’re doing research, but we all know they’re just sacrificing animals to appease the volcano gods.

Braving the INFERNO of a VOLCANO

Amazing plan to descend flaming crater hanging in cage from a derrick!

LOWERED to a depth of a thousand feet in the boiling, fume-filled crater of Mt. Mihara, near Tokio, Japan, scientists who are now carrying out an amazing program of volcanic investigations will hang in a tiny metal cage over a bubbling flood of molten lava, suspended only by a thin steel cable. Details of the device are given in the accompanying drawing. A live monkey, guinea pigs and rabbits were used in testing the toxicity of the volcano’s gases. Mt. Mikara is a favorite spot for suicides, 50 people having leaped to their death since January first.

SUN IS ENERGY SOURCE (May, 1929)

Well, he wasn’t misquoted. According to wikipedia he said:

“There is no likelihood man can ever tap the power of the atom. The glib supposition of utilizing atomic energy when our coal has run out is a completely unscientific Utopian dream, a childish bug-a-boo. Nature has introduced a few fool-proof devices into the great majority of elements that constitute the bulk of the world, and they have no energy to give up in the process of disintegration.” – 1928 at the Chemists’ Club (New York)

He also got the first Physics Ph.D from Columbia and discovered the mass and charge of the electron, which won him the Nobel prize in 1923 so I guess we can cut him a little slack.

SUN IS ENERGY SOURCE

OPINIONS of some natural scientists that man will some day be able to break down atoms and derive power from the energy contained within them were given a set-back recently when Dr. Robert A. Millikan, famous physicist, declared that experiments led him to believe that man will never have any other source of energy than the sun. Radiation from Old Sol is the source of all energy now used by man.

You Can’t Fool… Gravity (Sep, 1947)

You Can’t Fool… Gravity

You can trick the human eye, but you can’t fool gravity.

Can a body roll uphill? Yes. But doesn’t that violate the law of gravity? No. How come?

In school we learned that every body has a center of gravity the point at which all the weight of the body can be considered concentrated. Now, can a body roll uphill? Yes. But can the center of gravity roll uphill? No!

Remembering this will help you keep your balance over these two pages.
