    EDISON'S PHONOGRAPH
    November 21, 1877 - New York City, U.S.A.

    Thomas Edison announced his invention of his "talking machine" - the tin-foil cylinder recorder that preceeded the phonograph. He appears to have envisioned it as a business dictation machine. In Sep 1877, he wrote that its purpose was "to record automatically the speech of a very rapid speaker upon paper; from which he reproduces the same Speech immediately or years afterwards preserving the characteristics of the speakers voice so that persons familiar with it would at once recognize it." The indented tin foil, however, would survive only a few playings. By the first public showing of a phonograph, which took place in New York City in early Feb 1878, its practical applications had not yet been realized.

    WIRELESS TELEPHONE AT WHITE HOUSE
    November 21, 1919 - White House, U.S.A.

    President Wilson used a radio telephone set up on the south portico of the White House to direct the maneuvers of a dozen army airplanes flying over the Potomac river several miles away. His telephoned directions went direct to the flight commander in the air. The instrument was similar to those used by American aviators in France in the latter part of World War I. Col. C. C. Culver actively developed the equipment. He began the project in Aug 1910. No new invention was needed, only adaptation and adjustment of existing techniques. By Aug 1916, he was able to send a radio telegraph signal from a plane. Enlisting expert help from the telephone companies, by Oct 1917, voice messages could be send between a plane and the ground. The system was put into service for military wartime use.

Online Drugstores: Upside And Downside :

ARTICLE INFORMATION :

The article features online pharmacies as the most popular way of buying drugs in the USA and discusses the possible pitfalls that can arise out of obtaining drugs from some online pharmacies.

ARTICLE CONTENT :

Many people have already switched to online pharmacies and consider them a far more convenient way to purchase medicines. There are two primary reasons why people choose to purchase prescription medicines online. The first is financial. Because of the economic policy of the U.S. Health care, consumers frequently have to pay a much higher price for medications than customers overseas. The other reason is privacy. Some people prefer to purchase their prescription drugs from online pharmacies, even at a higher price, than to talk to a physician personally about medical conditions, such as depression, loss of hair, or erectile dysfunction.

Sales of antidepressant medicines, Viagra, Propecia, and diet pills, such as Phentermine or Xenical, are a flourishing business today. For years, consumers near Canada have driven across the border to buy medicines at an affordable price from Canadian pharmacies. These days, customers nationwide can buy from a Canadian pharmacy by mail. Canadian pharmacies typically require an identification document and a valid prescription. Unless issued by a doctor who is besides accredited to practice medicine in Canada, U.S. Prescription drugs will be reissued by a Canadian doctor.

As Internet pharmacies gain a larger share of the prescription medication market, consumers must be aware of the possible problems associated with purchasing an online prescription for a drug, or buying a medication online. These issues get even more significant when ordering from overseas pharmacies. It is usually possible to obtain savings by buying prescription medications online, even from a major U.S. Pharmacy, when you have a prescription issued to you personally.

It is commonly not cheaper to purchase medications through an online prescription service, which usually marks up the price substantially even when nominally offering a prescription for free. That mark-up may be compared to the cost of an in-person medical examination, and may considerably exceed that cost when you need a refill. Also, as mentioned above, price cannot always be the leading factor. If you don't know for certain whether you will be shipped the actual drug which was prescribed for you, think twice before ordering.
