Feature for Today
Thumbnail of Irving Langmuir

On 31 Jan 1881, Irving Langmuir was born, an American physical chemist who was awarded the 1932 Nobel Prize for Chemistry. In the Jun 1941 issue of Boys’ Life, Langmuir was featured to tell the Boy Scouts of America readers the value of summer jobs. Also of interest are his biographical remarks of his own boyhood experiences that contributed to his abilities as a research scientist and led to winning a Nobel Prize. Likewise, he also describes what drives his assistant, and gives him outstanding qualities. In the present, his message not only remains true, but is perhaps more urgent. Motivated students can still be recommended to seek a summer job that will challenge their intellectual development. Information students get by themselves is enormously more valuable than that which is taught to them in school. Students need opportunities—outside of school—to research, inquire, reason, get hands-on, explore, be curious and explain the phenomena around them. Students who succeed in these pursuits are the most likely to become the future research scientists and engineers. Teachers may wish to share this article on Irving Langmuir with their students, both boys and girls.


Book of the Day

On 31 Jan 1841, Sam Loyd was born, American puzzlemaker whose prolific output includes the famous “15” puzzle - a square tray tray containing 15 square tiles and one space that allows the tiles to be rearranged into a given pattern. Today's book pick is: , by , editted by Martin Gardner (author of the ‘Mathematical Games’ column in Scientific American), who describes Loyd as “America's greatest puzzlist and an authentic American genius.” This book contains a selection of thought-provoking problems and puzzles from Loyd's Cyclopedia in arithmetic, algebra, speed and distance problems, game theory, counter and sliding block problems.

Quotations for Today

There are few substances to which it [iron] yields in interest, when it is considered how very intimately the knowledge and properties and uses is connected with human civilization.

Train yourselves. Don’t wait to be fed knowledge out of a book. Get out and seek it. Make explorations. Do your own research work. Train your hands and your mind. Become curious. Invent your own problems and solve them. You can see things going on all about you. Inquire into them. Seek out answers to your own questions. There are many phenomena going on in nature the explanation of which cannot be found in books. Find out why these phenomena take place. Information a boy gets by himself is enormously more valuable than that which is taught to him in school.
— Irving Langmuir, American physical chemist (born 31 Jan 1881). quote icon

Thumbnail of Charles Green
Charles Green, born 31 Jan 1785, was an English balloonist whose outstanding achievement was his flight with two companions in 1836 from Vauxhall Gardens, London, to Weilburg, Germany, a distance of 480 miles. Green’s 18-hour trip set a long-distance balloon record for flights from England not beaten for many years

Thumbnail of André-Jacques Garnerin
On 31 Jan 1769, André-Jacques Garnerin was born, a French aeronaut who was the first person to use a parachute regularly and successfully. For his first jump, at age 28, he dropped from a hot-air balloon at 3000 feet. His parachute was semi-rigid, somewhat resembling an umbrella, and it shook back and forth violently during the fall.
What design change was needed to provide a smoother descent?
