🔗 Sexagesimal
Sexagesimal (also known as base 60 or sexagenary) is a numeral system with sixty as its base. It originated with the ancient Sumerians in the 3rd millennium BC, was passed down to the ancient Babylonians, and is still used—in a modified form—for measuring time, angles, and geographic coordinates.
The number 60, a superior highly composite number, has twelve factors, namely 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60, of which 2, 3, and 5 are prime numbers. With so many factors, many fractions involving sexagesimal numbers are simplified. For example, one hour can be divided evenly into sections of 30 minutes, 20 minutes, 15 minutes, 12 minutes, 10 minutes, 6 minutes, 5 minutes, 4 minutes, 3 minutes, 2 minutes, and 1 minute. 60 is the smallest number that is divisible by every number from 1 to 6; that is, it is the lowest common multiple of 1, 2, 3, 4, 5, and 6.
- In this article, all sexagesimal digits are represented as decimal numbers, except where otherwise noted. For example, 10 means the number ten and 60 means the number sixty.

🔗 Pilecki's Report
Witold's Report, also known as Pilecki's Report, is a report about the Auschwitz concentration camp written in 1943 by Witold Pilecki, a Polish military officer and agent of the Polish resistance. Pilecki volunteered in 1940 to be imprisoned in Auschwitz to organize a resistance movement and send out information about it. His was the first comprehensive record of a Holocaust death camp to be obtained by the Allies. He escaped from the camp in April 1943.
The report includes details about the gas chambers, "Selektion" and the sterilization experiments. It states that there were three crematoria in Auschwitz II able to cremate 8000 people daily.
Pilecki's Report preceded and complemented the Auschwitz Protocols, compiled from late 1943, which warned about the mass murder and other atrocities taking place inside the camp. The latter consists of the Polish Major's Report by Jerzy Tabeau, who escaped with Roman Cieliczko on 19 November 1943 and compiled a report between December 1943 and January 1944; the Vrba-Wetzler report; and the Rosin-Mordowicz report.

🔗 Gotthard Base Tunnel
The Gotthard Base Tunnel (GBT; German: Gotthard-Basistunnel, Italian: Galleria di base del San Gottardo, Romansh: Tunnel da basa dal Son Gottard) is a railway tunnel through the Alps in Switzerland. It opened on 1 June 2016, and full service began on 11 December 2016. With a route length of 57.09 km (35.5 mi), it is the world's longest railway and deepest traffic tunnel and the first flat, low-level route through the Alps. It lies at the heart of the Gotthard axis and constitutes the third tunnel connecting the cantons of Uri and Ticino, after the Gotthard Tunnel and the Gotthard Road Tunnel.
The link consists of two single-track tunnels connecting Erstfeld (Uri) with Bodio (Ticino) and passing below Sedrun (Graubünden). It is part of the New Railway Link through the Alps (NRLA) project, which also includes the Ceneri Base Tunnel further south (scheduled to open late 2020) and the Lötschberg Base Tunnel on the other main north–south axis. It is referred to as a "base tunnel" since it bypasses most of the existing Gotthard railway line, a winding mountain route opened in 1882 across the Saint-Gotthard Massif, which was operating at its capacity before the opening of the GBT. The new base tunnel establishes a direct route usable by high-speed rail and heavy freight trains.
The main purpose of the Gotthard Base Tunnel is to increase local transport capacity through the Alpine barrier, especially for freight, notably on the Rotterdam–Basel–Genoa corridor, and more specifically to shift freight volumes from trucks to freight trains. This both significantly reduces the danger of fatal road crashes involving trucks, and reduces the environmental damage caused by heavy trucks. The tunnel provides a faster connection between the canton of Ticino and the rest of Switzerland, as well as between northern and southern Europe, cutting the Basel/Zürich–Lugano–Milan journey time for passenger trains by one hour (and from Lucerne to Bellinzona by 45 minutes).
After 64 percent of Swiss voters accepted the NRLA project in a 1992 referendum, first preparatory and exploratory work began in 1996. The official start of construction began on 4 November 1999 at Amsteg. Drilling operations in the eastern tunnel were completed on 15 October 2010 in a breakthrough ceremony broadcast live on Swiss TV, and in the western tunnel on 23 March 2011. The tunnel's constructor, AlpTransit Gotthard AG, originally planned to hand over the tunnel to Swiss Federal Railways (SBB CFF FFS) in operating condition in December 2016 but, on 4 February 2014, the handover date was changed to 5 June 2016 with the start of an 850-day opening countdown calendar on the AlpTransit homepage. As of 1998, the total projected cost of the project was CHF 6.323 billion; as of December 2015, the final cost is projected as CHF 9.560 billion. Nine people died during construction.

🔗 Hoover Free Flights Promotion
The Hoover free flights promotion was a marketing promotion run by the British division of the Hoover Company in late 1992. The promotion, aiming to boost sales during the global recession of the early 1990s, offered two complimentary round-trip plane tickets to the United States, worth about £600, to any customer purchasing at least £100 in Hoover products. Hoover had been experiencing dwindling sales as a result of the economic downturn and a sharp increase in competing brands. Hoover was counting on most customers spending more than £100, as well as being deterred from completing the difficult application process, and not meeting its exact terms.
Consumer response was much higher than the company anticipated, with many customers buying the minimum £100 of Hoover products to qualify. It was perceived as two US flights for just £100 with a free vacuum cleaner included. The resulting demand was disastrous for the 84-year-old company. Hoover cancelled the ticket promotion after consumers had already bought the products and filled in forms applying for millions of pounds' worth of tickets. Reneging on the offer resulted in protests and legal action from customers who failed to receive the tickets they had been promised. The campaign was a financial disaster for the company and led to the loss of Hoover's Royal Warrant after the airing of a 2004 BBC documentary. The European branch of the company was eventually sold to one of its competitors, Candy, having never recovered from the losses, the promotion and the subsequent scandal.

🔗 Mulford Act
The Mulford Act was a 1967 California bill that repealed a law allowing public carrying of loaded firearms. Named after Republican assemblyman Don Mulford, and signed into law by governor of California Ronald Reagan, the bill was crafted with the goal of disarming members of the Black Panther Party who were conducting armed patrols of Oakland neighborhoods, in what would later be termed copwatching. They garnered national attention after Black Panthers members, bearing arms, marched upon the California State Capitol to protest the bill.
Assembly Bill 1591 was introduced by Don Mulford (R) from Oakland on April 5, 1967, and subsequently co-sponsored by John T. Knox (D) from Richmond, Walter J. Karabian (D) from Monterey Park, Frank Murphy Jr. (R) from Santa Cruz, Alan Sieroty (D) from Los Angeles, and William M. Ketchum (R) from Bakersfield. AB-1591 was made an “urgency statute” under Article IV, §8(d) of the Constitution of California after “an organized band of men armed with loaded firearms [...] entered the Capitol” on May 2, 1967; as such, it required a 2/3 majority in each house. It passed the Assembly (controlled by Democrats, 42:38) at subsequent readings, passed the Senate (controlled by Democrats, 20:19) on July 26 by 29 votes to 7, and was signed by Governor Ronald Reagan on July 28, 1967. The law banned the carrying of loaded weapons in public.
Both Republicans and Democrats in California supported increased gun control, as did the National Rifle Association of America. Governor Ronald Reagan, who was coincidentally present on the capitol lawn when the protesters arrived, later commented that he saw "no reason why on the street today a citizen should be carrying loaded weapons" and that guns were a "ridiculous way to solve problems that have to be solved among people of good will." In a later press conference, Reagan added that the Mulford Act "would work no hardship on the honest citizen."
The bill was signed by Reagan and became California penal code 25850 and 171c.

🔗 The Society in Dedham for Apprehending Horse Thieves
The Society in Dedham for Apprehending Horse Thieves is the "oldest continually existing horse thief apprehending organization in the United States, and one of Dedham's most venerable social organizations." Since its founding there have been more than 10,000 members including heads of state, Supreme Court justices, governors, popes, professors, generals, and other notables.
At one time membership of the "ancient and well known society" was limited to "the pillars of society" and the "very flower and pick of the vigor, manhood and rising youth of the vicinity." It has also been said that "for sheer whimsy, the Society... is without peer." Today it is a tax exempt non-profit social organization that continues to meet "just in case."

🔗 The Prague Pneumatic Post system (early mechanical networking)
The Prague pneumatic post (Czech: Pražská potrubní pošta) is the world's last preserved municipal pneumatic post system. It is an underground system of metal tubes under the wider centre of Prague, totaling about 55 kilometres (34 mi) in length. The system started service in 1889 and remained in use by the government, banks and the media until it was rendered inoperative by the August 2002 European floods.
Sold on by former owner Telefónica O2 Czech Republic after some limited attempts to make repairs, the system now belongs to businessman Zdeněk Dražil, who has announced plans to repair and reopen it as a working tourist attraction. As of 2012, however, it remains closed.
