The movement was initially named "Raise Your Voice", before it was renamed. The movement started from Ujjain in Madhya Pradesh, under the frontier-ship of the movement's four founders; with a "Langda March" at Ujjain. The movement opposes the Information Technology Act of India and demands democratic rules for the governance of Internet. The campaign is targeted at the rules framed under the Information Technology Act, 2000.

La France Insoumise
La France Insoumise (pronounced [la fʁɑ̃s ɛ̃sumiz]; variously translated as "Unbowed France", "Unsubmissive France", or "Rebellious France") is a democratic socialist, left-wing populist political party in France , launched on 10 February 2016 by Jean-Luc Mélenchon, then a Member of the European Parliament (MEP) and former co-president of the Left Party (PG). It aims to implement the ecosocialist programme L'Avenir en commun (English: "A Shared Future"). The party nominated Mélenchon as its candidate for the presidential election of 2017. He came fourth in the first round, receiving 19.5% of the vote and failing to qualify for the second round by around 2%. After the legislative election of 2017, La France Insoumise formed a parliamentary group of 17 members of the National Assembly, with Mélenchon as the group's president. In the 2019 European Parliament election, it however only won six seats, below its expectations. The party uses the lower case Greek letter phi as its logotype.

North African Climate Cycles
North African climate cycles have a unique history that can be traced back millions of years. The cyclic climate pattern of the Sahara is characterized by significant shifts in the strength of the North African Monsoon. When the North African Monsoon is at its strongest, annual precipitation and consequently vegetation in the Sahara region increase, resulting in conditions commonly referred to as the "green Sahara". For a relatively weak North African Monsoon, the opposite is true, with decreased annual precipitation and less vegetation resulting in a phase of the Sahara climate cycle known as the "desert Sahara". Variations in the climate of the Sahara region can, at the simplest level, be attributed to the changes in insolation because of slow shifts in Earth's orbital parameters. The parameters include the precession of the equinoxes, obliquity, and eccentricity as put forth by the Milankovitch theory. The precession of the equinoxes is regarded as the most important orbital parameter in the formation of the "green Sahara" and "desert Sahara" cycle. A January 2019 MIT paper in Science Advances shows a cycle from wet to dry approximately every 20,000 years.

Around the World Sailing Record
The first around the world sailing record for circumnavigation of the world was Juan Sebastián Elcano and the remaining members of Ferdinand Magellan's crew who completed their journey in 1522. The first solo record was set by Joshua Slocum in the Spray (1898). The current record holders are IDEC 3, skippered by Francis Joyon in 40 days, 23 hours, 30 minutes and 30 seconds for a crewed journey, and François Gabart with Macif in 42 days, 16 hours, 40 minutes and 35 seconds for a solo journey. Most races or solo attempts start from Europe. Due to the configuration of the continents, sailing around the world consists of sailing on the Southern Ocean around the Antarctica continent, passing south of Cape Horn, Cape of Good Hope and Cape Leeuwin. Since 1918 the Panama Canal is an option but the locks must be entered and exited using engine power. Large stretches of the canal can be crossed under sail power. Sailing around the world can be done by two directions: eastward or westward. The dominant winds and currents (outside tropical areas) make the voyage eastwards on the Southern hemisphere faster, most skippers and yachts who race prefer this route. Today, the multihulls perform much better than monohulls and hold the best times. Leisure yacht skippers who prefer tropical seas more often go westward, using the trade winds (and the Panama canal). The Jules Verne Trophy is awarded to the skipper who breaks the previous Jules Verne record, starting from an imaginary line between the Créac'h lighthouse on Ouessant (Ushant) Island, France , and the Lizard Lighthouse, United Kingdom . This has not always been the OUTRIGHT record. The records are homologated by the World Sailing Speed Record Council (WSSRC). According to the WSSRC, for around the world sailing records, there is a rule saying that the length must be at least 21,600 nmi calculated along the shortest possible track from the starting port and back that does not cross land and does not go below 63°S. The great-circle distance formulas are to be used, assuming that the great circle length is 21,600 nmi. It is allowed to have one single waypoint to lengthen the calculated track. The equator must be crossed. In reality, this means that the boat should pass a waypoint at or not far from the antipode of the starting port of the journey (the exact position depends on how short the shortest possible track is). For example, the Vendée Globe starts at 46°N 2°W, has a waypoint at 57°S 180°E, and barely makes the distance requirement. The participants don't have to go to the antipode at 46°S 178°E since the rounding of Africa gives extra distance.

Mannequin Challenge
File:Mannequin challenge JU Engineers.webm The Mannequin Challenge was a viral Internet video trend which became popular in November 2016, in which people remain frozen in action like mannequins while a moving camera films them, often with the song "Black Beatles" by Rae Sremmurd playing in the background. The hashtag #MannequinChallenge was used for popular social media platforms such as Twitter and Instagram. It is believed that the phenomenon was started by students at a high school in Jacksonville, Florida. The initial posting has inspired works by other groups, especially professional athletes and sports teams, who have posted increasingly complex and elaborate videos. News outlets have compared the videos to bullet time scenes from science fiction films such as The Matrix, X-Men: Days of Future Past, X-Men: Apocalypse, Lost in Space or Buffalo '66. Meanwhile, the participatory nature of the challenge on social media makes it similar to memes such as Makankosappo or the Harlem Shake. Others have noted similarities with the HBO TV series Westworld, which debuted around the same time, where robotic hosts can be stopped in their tracks.

Tesla Roadster (2008)
The Tesla Roadster is a battery electric vehicle (BEV) sports car, based on the Lotus Elise chassis, that was produced by the electric car firm Tesla Motors (now Tesla, Inc.) in California from 2008 to 2012. The Roadster was the first highway legal serial production all-electric car to use lithium-ion battery cells and the first production all-electric car to travel more than 320 kilometres (200 mi) per charge. It is also the first production car to be launched into orbit, carried by a Falcon Heavy rocket in a test flight on February 6, 2018. Tesla sold about 2,450 Roadsters in over 30 countries, and most of the last Roadsters were sold in Europe and Asia during the fourth quarter of 2012. Tesla produced right-hand-drive Roadsters from early 2010. The Roadster qualified for government incentives in several nations. According to the U.S. EPA, the Roadster can travel 393 kilometres (244 mi) on a single charge of its lithium-ion battery pack, and can accelerate from 0 to 97 km/h (0 to 60 mph) in 3.7 or 3.9 seconds depending on the model. It has a top speed of 201 km/h (125 mph). The Roadster's efficiency, (As of September 2008), was reported as 120 MPGe (2.0 L/100 km). It uses 135 Wh/km (21.7 kW·h/100 mi, 13.5 kW·h/100 km or 490 kJ/km) battery-to-wheel, and has an efficiency of 88% on average.
