This past week, a FedEx employeefrom Germantown, Tenn., made a massive discovery — and it wasn't in anypackages. John Pace found the largest prime number known to humankind.
And that number goes on to morethan 23 million digits.
"So it's longer than anybodyreally wants to sit down and hear," he says.
If you're not great at math, here'sa primer: Prime numbers can only be divided by 1 and themselves.
Pace found his prime as part of anonline collective called the Great InternetMersenne Prime Search, or GIMPS. Pace and thousands of volunteersran software on their personal computers crunching numbers day-in and day-out.
GT: 过去一周,来自田纳西州Germantown的联邦快递员工发现了一个巨大的发现,而且没有任何包装。约翰·佩斯发现了人类所知道的最大的素数。
这个数字超过了2300万位。
“所以比任何人想要坐下来听的时间都长,”他说。
如果你不擅长数学,那么这里有一个引子:素数只能被1和他们自己分开。
佩斯发现他的主要作为一个在线集体称为大互联网梅森素搜索,或GIMPS的一部分。步伐和成千上万的志愿者在他们的个人电脑上运行软件,日复一日地处理数字。
Mine: 过去一周,来自田纳西州German镇的联邦快递员有了一个巨大的发现,而且跟快递包没有关系。约翰·佩斯发现了人类至今所知道的最大的素数。
这个数字超过了2300万位。
“所以,没有人想坐下来听我念这个数字,”他说。
如果你不擅长数学,那么你需要知道这个最基本的知识:素数只能被1和该数整除。
佩斯是一个“在线集体”的成员,该集体称为“大互联网梅森素搜索,或GIMPS”。他和成千上万的志愿者在他们的个人电脑上运算,日复一日地处理着数字。
Anyone can participate, you justneed a computer, an internet connection and a lot of patience. Pace began hisprime hunt 14 years ago.
"There was a $100,000 prizeattached to finding the first prime that had a 10 million digit result, and Iwas like, 'Well you know, I've got as much chance as anybody else,' " hesays.
Pace's prime holds the title forthe largest, but there are other bigger ones out there. And they're important,especially when it comes to cryptography, internet security and the future of computing.
GT: 任何人都可以参与,你只需要一台电脑,互联网连接和耐心。佩斯14年前开始了他的主要追捕。
他说:“获得了1000万位数的第一个素数的奖金达到了10万美元,我想,'你知道,我和其他人一样有机会'。
佩斯的总理拥有最大的头衔,但还有其他更大的头衔。而且它们很重要,特别是在密码学,网络安全和计算的未来。
Mine: 任何人都可以参与,你只需要一台电脑、互联网连接和耐心。佩斯14年前开始了他的“素数追捕“。
他说:“获得了1000万位数的第一个素数的奖金,是10万美元。我想,'我和其他人的机会是等同的'。
佩斯的素数是至今发现的最大,但还有其他更大的。素数很重要,特别是在密码学、网络安全和计算学的未来。
"When they ultimately get toquantum computers, however long that takes, they'll be able to crack currentencryption in milliseconds," Pace says. "So there's going to be a need for extremely large prime numbers, and I'd like to at least have left some legacy that I've helped contribute something to society."
GT: “当他们最终到达量子计算机时,无论多长时间,他们将能够毫秒级地破解当前的加密,”佩斯说。所以我们需要一个非常大的素数,而且我至少要留下一些我曾经为社会贡献的东西。”
Mine: “无论我们需要等待多长时间,当最终有了量子计算机时,这些量子计算机将能够在毫秒时间内破解密码,”佩斯说。“所以我们需要非常大的素数。至少,我为社会做出了一点有意义的贡献。”
