🔗 Gauge blocks, a system for producing precision lengths
Gauge blocks (also known as gage blocks, Johansson gauges, slip gauges, or Jo blocks) are a system for producing precision lengths. The individual gauge block is a metal or ceramic block that has been precision ground and lapped to a specific thickness. Gauge blocks come in sets of blocks with a range of standard lengths. In use, the blocks are stacked to make up a desired length.
An important feature of gauge blocks is that they can be joined together with very little dimensional uncertainty. The blocks are joined by a sliding process called wringing, which causes their ultra-flat surfaces to cling together. A small number of gauge blocks can be used to create accurate lengths within a wide range. By using 3 blocks at a time taken from a set of 30 blocks, one may create any of the 1000 lengths from 3.000 to 3.999 mm in 0.001 mm steps (or .3000 to .3999 inches in 0.0001 inch steps). Gauge blocks were invented in 1896 by Swedish machinist Carl Edvard Johansson. They are used as a reference for the calibration of measuring equipment used in machine shops, such as micrometers, sine bars, calipers, and dial indicators (when used in an inspection role). Gauge blocks are the main means of length standardization used by industry.

🔗 Thomas Salme
Thomas Harry Salme (born 18 February 1969, in Stockholm) was convicted of flying passenger jets without a commercial pilot's license. After working as a First Officer and Captain from 1997 to 2010 for several international airline companies, Salme was arrested at Amsterdam's Schiphol Airport in March 2010.
🔗 Sámi National Day
The Sámi National Day is an ethnic national day for the Sámi (Saami) people that falls on February 6, the date when the first Sámi congress was held in 1917 in Trondheim, Norway. The congress was the first time that Norwegian and Swedish Sámi came together across national borders to work on finding solutions to common problems.
In 1992 at the 15th Sámi Conference in Helsinki, Finland, a resolution was passed that Sámi National Day should be celebrated on February 6 to commemorate the first Sámi congress in 1917, that Sami National Day is for all Sámi, regardless of where they live, and on that day the Sámi flag should be flown and the Sámi anthem sung in the local Sámi language. The first time Sami National Day was celebrated was in 1993, when the International Year of Indigenous People was proclaimed open in Jokkmokk, Sweden by the United Nations.
Since then, celebrating the day has become increasingly popular. In Norway, it is compulsory for municipal administrative buildings to fly the Norwegian flag, and optionally also the Sami flag, on February 6. Particularly notable is the celebration in Norway's capital Oslo, where the bells in the highest tower of Oslo City Hall play the Sami national anthem as the flags are raised. Some larger places have taken to arranging festivities in the week around the Sami National Day. The National Day has been included in the almanacs published by the University of Helsinki since 2004. The Norwegian, Swedish, and Finnish authorities recommend general flagging on the day.
By coincidence, February 6 was also the date representatives of the Sámi of the Kola Peninsula gathered annually to meet with Russian bureaucrats to debate and decide on issues of relevance to them. This assembly, called the Kola Sobbar, has been dubbed the "first Sámi Parliament" by the researcher Johan Albert Kalstad. However, the founding of the Kola Sobbar did not influence the choice of the date for Sámi People's Day, as the assembly existed only during the late 1800s and was largely forgotten until the early 2000s.

The Wallenberg family are a prominent Swedish family, Europe's pre-eminent, most powerful business family and dynasty, renowned as bankers, industrialists, politicians, bureaucrats, and diplomats.
The Wallenberg sphere's holdings employ about 600,000 people and have sales of $154 billion a year.
The Wallenberg empire consists of 16 Wallenberg Foundations, Foundation Asset Management (FAM), Investor AB, Patricia Industries and Wallenberg Investments AB.
The Wallenbergs control and are majority owners of most large Swedish industrial groups, such as world leading telecommunication multinational Ericsson, Scandinavian and Baltic bank giant Skandinaviska Enskilda Banken, one of the world's largest paper and pulp multinationals Stora Enso, Wärtsilä, world's second largest appliance maker Electrolux, one of the world's largest power, automation and robotics multinationals ABB, one of Europe's largest aerospace and arms manufacturers SAAB, SAS Group, world's largest ball-bearing company SKF, Atlas Copco, pharmaceutical multinational Astra Zeneca, Nasdaq, Inc., Husqvarna, the Stockholm football club AIK, investment company Investor AB, the Grand Group hotel, BraunAbility, Epiroc, world's largest powdered metal company Höganäs AB, IPCO, Laborie, EQT Partners, Nefab, Permobil, Piab, Sobi, Sarnova, 3 Scandinavia, Kopparfors Skogar, Hylte Bruk AB and so on.
