42nd Known Mersenne Prime Found!
我们找到了第42个梅森素数！
On February 18, 2005, Dr. Martin Nowak from Germany, found the new largest known prime number, 225,964,951-1. The prime number has 7,816,230 digits! It took more than 50 days of calculations on Dr. Nowak's 2.4 GHz Pentium 4 computer. The new prime was independently verified in 5 days by Tony Reix of Grenoble, France using a 16 Itanium CPU Bull NovaScale 5000 HPC running the Glucas program by Guillermo Ballester Valor of Granada, Spain. A second verification was completed by Jeff Gilchrist of Elytra Enterprises Inc. in Ottawa, Canada using 15 days of time on 12 CPUs of a Compaq Alpha GS160 1.2 GHz CPU server at SHARCNET.
在2005年2月18日，来自德国的 Martin Nowak医生找到了新的梅森素数：225,964,951-1 这个数在是有史以来所找到的梅森素数中，最大的。这个梅森素数有7,816,230位！Nowak医生的奔四 2.4G电脑用了超过50天的时间来完成此项工作。这个新的梅森素数已经被法国Grenoble市的Tony Reix先生独立检测完毕。Tony Reix先生使用的16位CPU是Bull NovaScale 5000 HPC。完成这次独立检测用时大约5天。此次检测使用的程序是由西班牙Granada市的Guillermo Ballester Valor先生编译的。加拿大渥太华Elytra Enterprises有限公司的Jeff Gilchrist先生完成了对此梅森素数的第二此检验。他使用的是SHARCNET的12个Compaq Alpha GS160 1.2 GHz CPU。费时大约15天。
Dr. Martin Nowak, an eye surgeon in Michelfeld, Germany learned of GIMPS in April 1999 when he read an article in his newspaper, the "Frankfurter Allgemeine Zeitung". Dr. Nowak, a math hobbyist, started with one PC and as his practice grew so did his participation in GIMPS. Six years later, he has 24 computers doing calculations for GIMPS -- and one Mersenne Prime to his credit!
Martin Nowak的职业是眼科医生，他在德国的Michelfeld就职。他是在1999年4月，在一份名为《法兰克福大众报》的报纸里读到关于GIMPS的文章的。Nowak医生是一位数学爱好者。开始时他只有一台PC运算。随着他参与时间越长，在他帐号名下的PC也越来越多。6年以后，他已经发动了24台PC参与GIMPS的计算工作。他至今为止搜索到了1个梅森素数！
Perfectly Scientific, Dr. Crandall's company which developed the FFT algorithm used by GIMPS, makes a poster you can order containing the entire number. It is kind of pricey because accurately printing an over-sized poster in 1-point font is not easy! Makes a cool present for the serious math nut in your family.
Crandall博士的公司把GIMPS中的FFT算法应用到实际生产当中来，提高了产品的质量。Crandall先生名下印刷公司所出产的印刷品非常精细，以至于在特大型的海报中可以打印出字号非常小的字。这是很不简单的！所以Crandall博士的产品较为昂贵。这是送给数学爱好者的绝好礼物！
Dr. Nowak could not have made this discovery alone. In recognition of contributions made by tens of thousands GIMPS volunteers, credit for this new discovery will go to "Nowak, Woltman, Kurowski, et al". The discovery is the eighth record prime for the GIMPS project. Join now and you could find the next record-breaking prime! You could even win some cash.
Nowak医生不可能独自完成这一创举。在这荣誉背后有着好几万GIMPS志愿者的努力以及汗水。这项发现将会以“Nowak, Woltman, Kurowski, et al”命名。此次发现是GIMPS的第八项记录。欢迎参加GIMPS，下一个破天荒的梅森素数在等待您的发现！您将会得到一些现金以资鼓励。
