  • RSA numbers

    In mathematics, the RSA numbers are a set of large semiprimes (numbers with exactly two prime factors) that are part of the RSA Factoring Challenge. The challenge was to find the prime factors but it was declared inactive in 2007. It was created by RSA Laboratories in March 1991 to encourage research into computational number theory and the practical difficulty of factoring large integers.

    RSA Laboratories published a number of semiprimes with 100 to 617 decimal digits. Cash prizes of varying size were offered for factorization of some of them. The smallest RSA number was factored in a few days. Most of the numbers have still not been factored and many of them are expected to remain unfactored for many years to come. As of September 2013, 18 of the 54 listed numbers have been factored: the 17 smallest from RSA-100 to RSA-704, plus RSA-768.

    The RSA challenge officially ended in 2007 but people are still attempting to find the factorizations. According to RSA Laboratories, "Now that the industry has a considerably more advanced understanding of the cryptanalytic strength of common symmetric-key and public-key algorithms, these challenges are no longer active." Some of the smaller prizes had been awarded at the time. The remaining prizes were retracted.

    South Africa and weapons of mass destruction

    From the 1960s to the 1980s, South Africa pursued research into weapons of mass destruction, including nuclear, biological, and chemical weapons. Six nuclear weapons were assembled. Before the anticipated changeover to a majority-elected African National Congress government in the 1990s, the South African government dismantled all of its nuclear weapons, the first nation in the world which voluntarily gave up all nuclear arms it had developed itself.

    The country has been a signatory of the Biological Weapons Convention since 1975, the Treaty on the Non-Proliferation of Nuclear Weapons since 1991, and the Chemical Weapons Convention since 1995.

    Nuclear weapons

    The Republic of South Africa's ambitions to develop nuclear weapons began in 1948 after giving commission to South African Atomic Energy Corporation (SAAEC), the forerunner corporation to oversee nation's uranium mining and industrial trade. In 1957, South Africa reached an understanding with the United States after signing a 50-year collaboration under the U.S.-sanctioned programme, the Atoms for Peace. The treaty concluded the South African acquisition of a single nuclear research reactor and an accompanying supply of the Highly Enriched Uranium (HEU) fuel, located in Pelindaba. In 1965, the American subsidiary, the Allis-Chalmers Corporation, delivered the 20MW research nuclear reactor, SAFARI-1, along with ~90% HEU fuel to South African nuclear authority. In 1967, South Africa decided to pursue the plutonium capability and constructed its own reactor, SAFARI-2 reactor also at Pelindaba, that went critical using 606kg of 2% enriched uranium fuel, and 5.4 tonnes of heavy water, both supplied by the United States.

    Just Can't Win

    by: 10 Years

    You and I share the same reflection
    why dont you see that we cannot survive in this condition
    If you're cut, I'll bleed
    So go on carve into your own heart, I could use a new scar or a brand new start
    Slowly severing the only memories that bind us as one.
    I just dont know
    How to win with you
    And I cant let go, part of me is you.
    We have lost all communication when words fall on deaf ears
    I'm starting to feel a transformation.
    How did I get here?
    I dont recognize my own reflection its a ghost of what once was
    Gone from relative to stranger, separating body from mind
    I just dont know
    How to win with you
    And I cant let go, part of me is you.
    You stay the same
    Allowing me to change
    I just dont know
    How to win with you
    I cant let go, part of me is you.
    I just dont know, just dont know.
    I cant let go, cant let go.
