KTH…果然不是一般牛

    上帝啊,原谅我一天更新这么多次。。。
    实在是太牛逼了,我的娘,KTH主校区地下居然有个核反应堆,而且就在偶还不时去上课的Q楼底下。。。
    发现这个过程也曲折离奇。今天上万network security,在wiki上查上课讲的Kerberos,美国人搞得一套用于close environment的加密协议。看着看着,wiki上有一条说美国人比较贼,吃独食。Authorities in the United States classified Kerberos as a munition and banned its export because it used the DES encryption algorithm (with 56-bit keys). A non-US Kerberos 4 implementation, KTH-KRB developed at the Royal Institute of Technology in Sweden, made the system available outside the US before the US changed its cryptography export regulations (circa 2000). 而我们伟大的KTH搞了一套米国人之外的协议,赞一句,哈哈。不过今天上课老师为啥不提捏,真是奇怪咧。
    接着就分神点到kth那一项进去看了看,不小心就发现了这条惊天消息,哈哈哈。

R1

After the American deployment of nuclear weapons, the Swedish military leadership recognized nuclear weapons to be thoroughly investigated and researched to provide Sweden with the knowledge to defend itself from nuclear attack. At that time, Sweden knew virtually nothing about nuclear physics, as all information and research around were kept strictly confidential by the United States. With the mission to "make something with neutrons", the Swedish team, with scientists like Rolf Maximilian Sievert, set out to research the subject and eventually build a nuclear reactor for testing.

After a few years of basic research, they started building a 300 kW (later expanded to 1 MW) reactor, named "Reaktor 1", R1 for short, in a reactor hall 25 meters under the surface right underneath KTH. Today this might seem ill-considered, since approximately 40,000 people lived within a 1 km radius. It was risky, but were deemed tolerable since the reactor was an important research tool for scientists at the Royal Swedish Academy of Engineering Sciences (Ingenjörsvetenskapsakademien).

At 18:59, 13 July 1954, the reactor reached critical mass and sustained Sweden’s first nuclear reaction. R1 was to be the main site for almost all Swedish nuclear research until 1970 when the reactor was finally decommissioned, mostly due to the increased awareness of the risks associated with operating a reactor in a densely populated area of Stockholm. The reactor hall remains an amusement to many as once it was next door to what used to be Sweden’s first nuclear reactor. Close to the reactor hall is the restaurant Q.

希望已经木有辐射了啊。。。不然我们这帮人岂不是。。。哈哈~~~哈哈。。。
