    ARTIFICIAL LEG PATENT
    February 10, 1863 - U.S. Patent

    Dubois D. Parmelee was issued a U.S. patent for an "Improvement in Artificial Legs" using a custom-moulded suction cup to receive the stump (No. 37,637). Atmospheric pressure held the socket in place such that "straps usually employed for this purpose can be dispended with, and at the same time a perfect fit of the bucket is attained." On the underside of the bucket "a small faucet" was open as the stump was forced into the tightly fitting socket. The faucet was then closed, and atmospheric pressure held the bucket in place until air is readmitted through the faucet. It was 90 years before his idea received general acceptance. Parmelee also invented the first key-operated adding machine (Pat. No. 7,074, 5 Feb 1850).

  • The Revolution
    by John Adams

    "...The Revolution was effected before the War commenced. The Revolution was in the minds and hearts of the people; a change in their religious sentiments of their duties and obligations. This radical change in the principles, opinions, sentiments, and affections of the people, was the real American Revolution...."
  • A Change is Gonna Come
    by Meredith Grey

    "...Change; we don't like it, we fear it, but we can't stop it from coming. We either adapt to change, or we get left behind. It hurts to grow, anybody who tells you it doesn't is lying. But here's the truth: Sometimes the more things change, the more they stay the same. And sometimes, oh, sometimes change is good. Sometimes change is everything...."

There are a great many online services that offer online music. Some sites charge per online music download, whereas other services offer to pay a monthly fee for a limitless number of music downloads. It has been estimated that compact disc sales are in decline (19% in the last few years), and online music download sales are speedily increasing. Revenues from digital music sales are reported to have virtually tripled last year, with Apple's iTunes accounting for more than 85 percent of single song downloads. Nevertheless, the figures do not make Apple the sole source of digital music. Today, legal music download sites account for approximately 6% of record studios' revenues, which is a growth compared to the situation observed a couple of years ago.

Music download sites come in two types: 'rent' and 'buy' websites. 'Rent' sites are music sites involving a monthly fee paid to gain access to the whole music catalogue. 'Buy' services charge per download - iTunes, for example - where a soundtrack can be burned onto a CD once it is paid for. The CD can then be ripped to the pc. Some digital music services offer to pay a monthly fee for limitless listening rights, but also charge to purchase a song. Some digital music download sites charge 9 cents per track. In addition, these sites have tracks that can be downloaded in any format and quality level.

Sometimes music download websites are so cheap and user-friendly that a great many Internet users decide to download songs from these websites instead of ripping CD collections onto the personal computer. For any person downloading songs onto an iPod or iTunes, it is probably the optimum option. For any music not being downloaded onto an iPod, any other music source will work. When seeking the optimum quality music downloads, one should look for music download websites offering the largest choice of music that is updated on a regular basis, and excellent quality downloads. Commonly, the price is directly dependent on quality. In this case, a question arises: Is it worth spending extra money? The answer is typically 'Yes'.
