Every Family.. should own.. this Newest, Greatest Encyclopaedia Britannica (Mar, 1930)

I wonder how people would have reacted if, just once, the family shown in the picture was Black or Asian. “Every Family with Children” is a pretty all encompassing statement.

Every Family with Children in it should own and can own this Newest, Greatest Encyclopaedia Britannica

Every family, and above all, every family with children in it, should own the great new Encyclopaedia Britannica— the one essential book for the home — the one work bringing to young and old the limitless advantages of modern knowledge.

MAPS Spur New HUNT For Kidd Treasure (Nov, 1936)

MAPS Spur New HUNT For Kidd Treasure

by HAROLD T. WILKINS
Author of “Modern Buried Treasure Hunters”

I AM laying plans to land on a mysterious island in a far eastern ocean, to which a modern and seaworthy steam, or Diesel engined yacht will transport an old sea captain and navigator and myself many thousands of miles across two oceans from the quays and wharves of London and New York.

Science’s Greatest Adventure (Sep, 1930)

Science’s Greatest Adventure

To Richard E. Byrd and his hardy companions of the South Pole Expedition, this section of Modern Mechanics is dedicated. The photos reproduced herewith tell a graphic story of the South Polar Adventure.

WITH the return of Commander Richard E. Byrd and his crew of 80 men from the Antarctic, one of the most dramatic chapters in all history is brought to a close. That the Expedition, which for 20 months ferreted out the ice-locked secrets of the South Polar lands with airplanes, dog teams, and all the instruments of modern science, was an adventure which in its various phases of hardship and discovery ranks with the achievements of Magellan, Columbus, Hudson, and other great explorers, no one will seriously deny.

My Greatest Discovery in Fifty Years (Apr, 1923)

My Greatest Discovery in Fifty Years

Famous Plant Wizard, Celebrating Half a Century of Useful Labor, Tells How He Believes We Can Develop Better “Human Plants”

By Luther Burbank, Sc.D., Especially written for Popular Science Monthly

ON THE seventh day of March, I was 74 years of age. On that day, I celebrated the conclusion of half a century of ceaseless experimentation with plant life.

In those 50 years, millions of plants—grasses, flowers, vegetables, grains, and trees—have passed through my hands, and from them I have selected a few, seemingly a very, very few, for preservation, reproduction, improvement, development, to such a point that they may render the utmost service of food, beauty, and enjoyment to man.

He Made Sky Mapping a Big Business (May, 1936)

He Made Sky Mapping a Big Business

High above the broken floor of the Rio Grande River basin, an airplane growls monotonously over 32,000 square miles, each click of its Cyclopean camera bringing nearer to completion the largest photographic mapping project ever undertaken in the United States.

EXACTING and tedious is the scientific job of gathering up 32,000 square miles and literally pasting them in your hat. Only one man is utterly capable and he is the fellow who supervises the shooting and assembling of this vast mosaic.

What the Telephone Map Shows (Sep, 1914)

What the Telephone Map Shows

EVERY dot on the map marks a town where there is a telephone exchange, the same sized dot being used for a large city as for a small village. Some of these exchanges are owned by the Associated Bell companies and some by independent companies. Where joined together in one system they meet the needs of each community and, with their suburban lines, reach 70,000 places and over 8,000,000 subscribers.

The pyramids show that only a minority of the exchanges are Bell-owned, and that the greater majority of the exchanges are owned by independent companies and connected with the Bell System.

At comparatively few points are there two telephone companies, and there are comparatively few exchanges, chiefly rural, which do not have outside connections.

The recent agreement between the Attorney General of the United States and the Bell System will facilitate connections between all telephone subscribers regardless of who owns the exchanges.

Over 8,000 different telephone companies have already connected their exchanges to provide universal service for the whole country.

Uncle Sam’s Scientists DISPLAY THEIR CONTRIBUTIONS TO PROGRESS AT GREAT WORLD’S FAIR (Jun, 1933)

Uncle Sam’s Scientists DISPLAY THEIR CONTRIBUTIONS TO PROGRESS AT GREAT WORLD’S FAIR

By George H. Dacy

ACCOMPLISHMENTS of United States Government scientists, during the past one hundred years, will be revealed by impressive exhibits at the Century of Progress exposition which opens at Chicago next month. A building of unusual design, decorated in bizarre color combinations, will house the remarkable display.

No scientific or technical exhibit ever set up exceeded in scope, variety, splendor, and magnitude the continuous performance Uncle Sam will stage in this windowless Federal Building with its trio of sky-pointing towers representing the executive, judicial, and legislative branches of our government.

Revising the Map of America to Save a Nation (Nov, 1934)

Revising the Map of America to Save a Nation

By William Dyce

DISASTER threatens the United States. Productive farm lands are becoming desolate deserts. Cleared lands, where once stood thick forests, are being ravaged by destructive floods. Uncle Sam is in danger of losing hundreds of thousands of acres that are now helping to feed his 125,000,000 citizens.

To avert the threatened calamity the government is in effect revising the geography of the country. Where waste land now exists, happy farmers are expected to till a productive soil. Where flat prairies sweep to horizons on all sides, great forests will arise. Where rivers never existed, water will flow. Shallow, sluggish streams will become principal arteries of commerce. And, in some cases, where civilization rules today, a wilderness will exist tomorrow.

Test Your Wits on These Mathematical Puzzles (Mar, 1932)

The Four Color Theorem was not proven until 1976 and required the use of a computer.

I’m pretty sure the thing about arabic numerals representing the number of angles in their characters is total B.S.

Test Your Wits on These Mathematical Puzzles

by WILLIAM J. HARRIS

There’s nothing like a puzzle to test one’s mental alertness, and those presented here by Mr. Harris are certainly corkers. He also gives you some simple tricks which, though they only take a few minutes to learn, will convince your friends that you are a mathematical wizard of the first water. (P. S.— Answers are in the back of the book!)

Problems, Too, Have Problems (Oct, 1961)

This is a veryforward thinking article. It talks about a lot of things that are only getting widespread adoption now including image recognition, parallel processing and mainly general purpose problem solvers like Siri, Wolfram Alpha and Google’s new (and very impressive) Voice Search. I think that what the authors, nor really anyone else at the time, didn’t anticipate just how much more complex and miniaturized computers would become and just how much processing power and data storage would be necessary to perform these tasks.

Problems, Too, Have Problems

by John Pfeiffer

A dialogue, perhaps to become one of the most fruitful in history, has begun between the men who study the human brain and those who design computers. Point of agreement: the brains and the computers need each other desperately.

Ever since man started making tools to tinker with nature one to two million years ago, he has been getting into—and, so far, out of—more and more elaborate kinds of trouble.
