A Muon Cellphone Sometime

“In April a sequence of Morse-code V’s (dot dot dot sprint) was transmitted by a beam of muons that handed by a five-foot wall and traveled 150 meters earlier than reaching a ‘terminal’ consisting of two coincidence counters. The message was encoded by mechanically interposing or not interposing a three-inch block of brass within the muon beam each time a 12-billion-electron-volt synchrotron on the Argonne Nationwide Laboratory emitted a brief burst of particles. The experiment was the primary recognized use of a particle accelerator to transmit a message. Richard C. Arnold, who carried out the experiment, means that muon beams are doubtlessly aggressive with microwave-relay and satellite tv for pc programs for long-range communication. Arnold says: ‘Designing and growing muon communication programs ought to present expertise that will probably be priceless in designing related programs with neutrino beams. Such programs await the event of sufficiently large detectors and sufficiently intense or energetic (or each) accelerator beams.’”

Nanoseconds Misplaced

“Atomic clocks are getting correct sufficient to straight take a look at the final principle of relativity. If a clock is taken in an airplane and flown world wide eastward (the route through which the earth rotates), it ought to run gradual with respect to reference clocks on the Naval Observatory and lose time. If the clock have been flown world wide westward, it might run quick. In October, J. C. Hafele and Richard E. Keating took 4 cesium-beam clocks made by Hewlett-Packard on usually scheduled business flights world wide, as soon as in every route. The flying clocks misplaced 59±10 nanoseconds through the eastward journey and gained 273±7 nanoseconds through the westward journey, verifying the predictions of the final principle of relativity. The experiment will be the least expensive ever carried out to check the speculation; it value some $8,000, of which $7,600 was spent on air fare.”

A Helicopter That Flies

“After practically 20 years of experimentation, the well-known inventor, Emile Berliner of Washington, D.C., and his son, Henry A. Berliner, have perfected the primary profitable helicopter which can rise perpendicularly and fly forward. The aviator can direct its course whichever method he wishes by tilting it ahead so that it’ll fly horizontally. This tilting is completed by a small horizontal propeller situated on the tail of the machine. In the course of the exams the helicopter has not been operated at heights better than 15 to twenty ft, and it has been flown at a pace of about 20 miles an hour. About the perfect many different inventors have completed was to develop machines which might rise from the bottom, however which failed of their efforts to fly ahead on even keel.”

Ox Blood Cures Ills

“In medication, sure issues are in vogue for a sure time. Bleeding and mercury have had their day; cod liver oil and chloral hydrate are already on the wane; alcohol and bullock’s blood are actually in vogue among the many Parisians—the previous for fevers and all inflammatory affections, and the latter for anaemia and pulmonary phthisis. It’s stated to be a curious sight in Paris to see sufferers of each sexes and all ages who flock to the slaughter home each morning to drink of the nonetheless fuming blood of the oxen slaughtered for the desk. In response to M. Boussingault, of all nutritive substances, the blood of animals accommodates the best amount of iron, and it’s this which supplies worth to the brand new medication.”

Unimaginable Sunflower

“A recent calls consideration to the vital makes use of of the sunflower. It can develop virtually anyplace, and the rising plant and its flowers are well-known absorbents of foul and miasmatic air. It is rather productive of seed, yielding fifty bushels to the acre, which comprise fifty gallons of simply expressed oil. The oil is instantly burnt in lamps, and provides a transparent white mild; it may be used as a car for paint, and is great for the soapmaker. The seeds will also be fed to poultry in winter, with benefit. The stalks yield a priceless product, a fiber of nice energy and smoothness, which might be obtained by ‘retting,’ as is finished with the stalks of flax.”
