π United States Camel Corps
The United States Camel Corps was a mid-19th-century experiment by the United States Army in using camels as pack animals in the Southwestern United States. While the camels proved to be hardy and well suited to travel through the region, the Army declined to adopt them for military use. The Civil War interfered with the experiment and it was eventually abandoned; the animals were sold at auction.

π Koomey's law
Koomey's law describes a trend in the history of computing hardware: for about a half-century, the number of computations per joule of energy dissipated doubled about every 1.57 years. Professor Jonathan Koomey described the trend in a 2010 paper in which he wrote that "at a fixed computing load, the amount of battery you need will fall by a factor of two every year and a half."
This trend had been remarkably stable since the 1950s (R2 of over 98%). But in 2011, Koomey re-examined this data and found that after 2000, the doubling slowed to about once every 2.6 years. This is related to the slowing of Moore's Law, the ability to build smaller transistors; and the end around 2005 of Dennard scaling, the ability to build smaller transistors with constant power density.
"The difference between these two growth rates is substantial. A doubling every year and a half results in a 100-fold increase in efficiency every decade. A doubling every two and a half years yields just a 16-fold increase", Koomey wrote.

π Kyshtym Disaster
The Kyshtym disaster, sometimes referred to as the Mayak disaster or Ozyorsk disaster in newer sources, was a radioactive contamination accident that occurred on 29 September 1957 at Mayak, a plutonium production site for nuclear weapons and nuclear fuel reprocessing plant located in the closed city of Chelyabinsk-40 (now Ozyorsk) in Chelyabinsk Oblast, Russian SFSR, Soviet Union.
The disaster was the second worst nuclear incident (by radioactivity released) after the Chernobyl disaster. It measured as a Level 6 disaster on the International Nuclear Event Scale (INES), making it the third highest on the INES (which ranks by population impact), behind Chernobyl (evacuated 335,000 people) and the Fukushima Daiichi nuclear disaster (evacuated 154,000 people) which are both Level 7 on the INES. At least twenty-two villages were exposed to radiation from the Kyshtym disaster, with a total population of around 10,000 people evacuated. Some were evacuated after a week, but it took almost two years for evacuations to occur at other sites.
The disaster spread hot particles over more than 52,000 square kilometres (20,000Β sqΒ mi), where at least 270,000 people lived. Since Chelyabinsk-40 (later renamed Chelyabinsk-65 until 1994) was not marked on maps, the disaster was named after Kyshtym, the nearest known town.

π Community Memory Terminal
Community Memory (CM) was the first public computerized bulletin board system. Established in 1973 in Berkeley, California, it used an SDS 940 timesharing system in San Francisco connected via a 110 baud link to a teleprinter at a record store in Berkeley to let users enter and retrieve messages. Individuals could place messages in the computer and then look through the memory for a specific notice.
While initially conceived as an information and resource sharing network linking a variety of counter-cultural economic, educational, and social organizations with each other and the public, Community Memory was soon generalized to be an information flea market, by providing unmediated, two-way access to message databases through public computer terminals. Once the system became available, the users demonstrated that it was a general communications medium that could be used for art, literature, journalism, commerce, and social chatter.

π San Jose electric light tower
The San Jose electric light tower, also known as Owen's Electric Tower after its creator and chief booster, was constructed in 1881 at an intersection in downtown San Jose, California, as a "high light" or moonlight tower to light the city using arc lights. A pioneer use of electricity for municipal lighting, it was later strung with incandescent bulbs and was destroyed in a storm in December 1915. A half-size replica stands at History Park at Kelley Park.

π 1957 German Grand Prix
The 1957 German Grand Prix was a Formula One motor race held on 4 August 1957 at NΓΌrburgring. It was race 6 of 8 in the 1957 World Championship of Drivers. The 22 lap race was won by Juan Manuel Fangio, and is often cited as one of the greatest victories in racing history. It was Fangio's fourth victory out of the seven races in the season contested by Formula 1 cars - excluding the Indianapolis 500, in which only US drivers competed, using USAC Championship cars. Furthermore, due to the number of points he had accumulated in the season (34 to Luigi Musso's 16), his victory at the NΓΌrburgring mathematically clinched Fangio's fifth World Championship title with two races to go. The race was also notable for being Fangio's 24th and last victory in F1; his career still stands as having the highest win percentage ever, with 46.15% of his 52 race entries being wins.

π Death of Gloria Ramirez
Gloria Ramirez (January 11, 1963 β February 19, 1994) was a woman from Riverside, California who was dubbed "the Toxic Lady" or "the Toxic Woman" by the media when several hospital workers became ill after exposure to her body and blood. She had been admitted to the emergency department while suffering from late-stage cervical cancer. While treating Ramirez, several hospital workers fainted and others experienced symptoms such as shortness of breath and muscle spasms. Five workers required hospitalization, one of whom remained in an intensive care unit for two weeks.
Shortly after arriving at the hospital, Ramirez died from complications related to cancer. The incident was initially considered to be a case of mass hysteria. An investigation by Lawrence Livermore National Laboratory proposed that Ramirez had been self-administering dimethyl sulfoxide as a treatment for pain, which converted into dimethyl sulfate, an extremely poisonous and highly carcinogenic alkylating agent, via a series of chemical reactions in the emergency department. Although this theory has been endorsed by the Riverside Coroner's Office and published in the journal Forensic Science International, it is still a matter of debate in the scientific community.

π World War III
World War III or the Third World War, often abbreviated as WWIII or WW3, are names given to a hypothetical third worldwide large-scale military conflict after World WarΒ I and World WarΒ II. The term has been in use since at least as early as 1941. Some apply it loosely to limited or more minor conflicts such as the Cold War or the war on terror. In contrast, others assume that such a conflict would surpass prior world wars in both scope and destructive impact.
Due to the development and use of nuclear weapons near the end of World WarΒ II and their subsequent acquisition and deployment by many countries, the potential risk of a nuclear apocalypse causing widespread destruction of Earth's civilization and life is a common theme in speculations about a Third World War. Another primary concern is that biological warfare could cause many casualties. It could happen intentionally or inadvertently, by an accidental release of a biological agent, the unexpected mutation of an agent, or its adaptation to other species after use. Large-scale apocalyptic events like these, caused by advanced technology used for destruction, could render Earth's surface uninhabitable.
Before the beginning of World War II in 1939, World WarΒ I (1914β1918) was believed to have been "the war to end [all] wars." It was popularly believed that never again could there possibly be a global conflict of such magnitude. During the interwar period, World War I was typically referred to simply as "The Great War". The outbreak of World WarΒ II disproved the hope that humanity might have already "outgrown" the need for such widespread global wars.
With the advent of the Cold War in 1945 and with the spread of nuclear weapons technology to the Soviet Union, the possibility of a third global conflict became more plausible. During the Cold War years, the possibility of a Third World War was anticipated and planned for by military and civil authorities in many countries. Scenarios ranged from conventional warfare to limited or total nuclear warfare. At the height of the Cold War, the doctrine of mutually assured destruction (MAD), which determined an all-out nuclear confrontation would destroy all of the states involved in the conflict, had been developed. The absolute potential destruction of the human race may have contributed to the ability of both American and Soviet leaders to avoid such a scenario.

π Hebban Olla Vogala
"Hebban olla vogala", sometimes spelled "hebban olla uogala", are the first three words of an 11th-century text fragment written in Old Dutch. The fragment was discovered in 1932 on the flyleaf of a manuscript that was probably made in the abbey of Rochester, Kent and is kept in Oxford. It is usually considered to represent a West Flemish variant of Old Low Franconian.
An often cited poem, it was long believed by many Dutch people to be the only text remaining of Old Dutch. However, experts were already aware of other sources that were then not yet easily accessible. Today, more than 42,000 Old Dutch words and phrases from sources such as the Wachtendonck Psalms and the Leiden Willeram have been discovered, with the oldest definitive source being the Salian Law.
