Calculating Machine is built of Toy Parts
CONSTRUCTED entirely from the wheels, gears and structural members of a popular construction toy set, an amazing calculating machine at Manchester University, England can do in a few minutes problems which ordinarily would require many days of tedious work by mathematicians. The only other machine of its kind is at Boston, Mass. When experiments on this machine have been completed, Mr. A. Porter and Professor Hartree, its builders, propose to make a larger model, 27 feet long and 12 feet wide.
When a man-size spider walks a giant web, when scissors draw the villain’s blood or a lobster spits in the waiter’s eye, put it down to
SEATED AT A SIDEWALK TABLE in a Paris cafe, a customer watched in fascination a huge, freshly cooked lobster placed in front of him by the waiter. Each time he reached for the lobster the huge shellfish swiftly moved its large claws protectingly over its head. Reaching for a hammer, the would-be diner attempted to hit the lobster but each time the claws parried the blow. The man finally called the waiter to see what he could do with the reluctant lobster. As the waiter bent over to inspect the lobster and its strange actions more closely a stream of water hit him in the eye.
How THREE COLOR MOVIES ARE MADE
WOULD you like to know how the color in a Walt Disney Silly Symphony or in “La Cucaracha” is obtained? Have you ever wondered how a motion picture film, in which each picture is about the size of a postage stamp, is colored so it can be magnified 35,000 or more times and still retain the beautiful coloring of a Silly Symphony?
Device Measures Musical Talent
A YARDSTICK for the measurement of musical talent, an automatic tone-variator, is now being used at Northwestern University to determine students’ ability to determine exact tonal pitch.
The machine contains 14 tuning-forks, set within one-quarter tone of each other. Two notes are struck in quick succession, and the students are asked which note was higher. Those that can detect the higher note consistently are keenly encouraged to study music. They are considered to be musically apt and talented.
Students with less sensitivity to tone are advised to study instruments with broader tone distinctions such as pianos and other keyboard instruments.
How Comic CARTOONS Make Fortunes
The “funnies” you read every day bring $8,000,000 a year to a small group of 200 cartoonists. How they rose to the top and how you can enter their select circle is told here by leading comic artists.
THAT laugh you had today over your favorite funny strip is worth moneyâ€” $200 to $1,000 a day to the cartoonist that made you chuckle.
His pen and ink characters are part of a great $8,000,000 industry that is far from overcrowded and that is practically depression proof.
Of the 200 successful cartoonists today the majority were not “born artists.” In many cases they were not artists at all, but just fellows with a knack for sketching who thought of a good idea or a funny character that “made a hit” with an editor and eventually with newspaper readers.
CREATING A NEW WORLD WITH ELECTRONICS
How far away is the pocket-size TV camera?
Samples were used at the last political conventions.
Production modelsâ€”built around subminiaturized circuits requiring semiconductorsâ€”can be expected any day. The proved reliability of Hughes diodes, even under severe shock or weather conditions, makes these tiny, compact semiconductors a logical choice for such circuits.
German Boys Build Scale Model Liners for Sea Cruises
EXPERT marine constructionists, between the ages of 9 and 16 are being developed in one of the most novel trade schools of the world at Potsdam, Germany. Under the tutelage of experienced marine engineers, the youths receive a thorough technical training in building exact replicas of real steamships on a scale of one to twenty.
Grades are given according to the aptitude and intelligence shown in building the model vessels. The plans from which the youth work are the same plans, scaled down, of such ships
as the Normandie and the Queen Mary. At the end of the school year, advanced students build models that can actually go to sea.
Power It with a PULSE JET
THIS model plane project uses what may be the smallest successful pulse-jet engine ever built. It was developed after scores of experiments and the building of a dozen test models by Hiram Sibley, Jr., a California guided-missile engineer.
Automat Swaps Candy for Bottles
TO INSURE the return of empty milk bottles and eliminate the cost of replacements, an automat has been devised which dispenses candy and gum in exchange for “empties.” Shaped and painted like a huge milk bottle, the container has a capacity of 60 bottles. The empty bottle is placed on a red hook in an opening near the top and a handle is pushed to the right to deposit the bottle. Gum or candy is discharged into the customer’s hands.
Strictly Fresh Ideas for Easter Eggs
IF THE eggs used in making these novelties are blown’ by the method illustrated, the contents may be used for the table in the form of an omelet or scrambled. Clean the shell with soap and warm water, es–pecially if water colors are used in decorating. Sails, wings, legs, and other parts may be fastened on with model-airplane cement. Features are modeled in artist’s clay of the self-hardening type.â€”Hi Sibley.
