Fight over Captain Cook's legacy heats up ahead of 250th anniversary

  Fight over Captain Cook's legacy heats up ahead of 250th anniversary The Greens have been criticised after calling for commemorative events marking the 250th anniversary of Captain Cook's landing in Australia to be scrapped. Leader Adam Bandt declared they were not "an appropriate way to mark history because it's not being honest about the dark sides of Australia's history."One Nation leader Pauline Hanson labelled that "absolute rubbish".© 9News The voyage of Captain James Cook is the subject of a culture war over whether or not celebrations of the event are respectful to Indigenous Australians.

The land speed record (or absolute land speed record ) is the highest speed achieved by a person using a vehicle on land . There is no single body for validation and regulation

Land Speed Record is the debut full-length record by Hüsker Dü, released in January 1982. It was recorded live on August 15, 1981, at the 7th Street Entry, a venue in Minneapolis, Minnesota. The album is a fast and furious hardcore workout that bears almost no resemblance to the melodic

The first rover ever to visit the far side of the moon has discovered a layer of lunar dust up to 12 meters (39 feet) deep.

The rover and its lander, which sits in the moon's Von Kármán crater, are part of China's Chang'e-4 mission. Their landing there on January 3, 2019 marked the first time any spacecraft had ever visited the far side of the moon without crashing.

The rover measured the moon's surface dust with radar for the first time, and researchers from China and Italy described the results in a paper published Wednesday in the journal Science Advances.

How A Piece Of Tape Tricked A Tesla Into Reading A 35MPH Sign As 85MPH

  How A Piece Of Tape Tricked A Tesla Into Reading A 35MPH Sign As 85MPH Researchers have identified a potential issue with sensors used in some older Tesla models that misinterpreted speed signs to read the speed limit as 50 miles per hour greater than the sign stated when a piece of electrical tape slightly obscured one of the numbers. The issue was identified as part of 18 months of research by McAfee researchers Shivangee Trivedi and Mark Bereza, who sought to examine the ways that machine learning could potentially be exploited, specifically in the case of autonomous vehicles.

Lunar dust, also called regolith, is a talc-like substance of pulverised rock and dust that settled after asteroids bombarded the moon's surface billions of years ago. The Chang'e 4 findings confirm that this dust also coats the far side of the moon, in a layer that the scientists described as "quite thick."

"This work shows that the extensive use of the [Chang'e 4 radar] could greatly improve our understanding of the history of lunar impact and volcanism and could shed new light on the comprehension of the geological evolution of the moon's far side," the study authors wrote.

That understanding will be key for future missions to the moon. Lunar dust can cloud a spacecraft's instruments as it approaches the moon's surface, raising the risk of failure.

Kim Kardashian and Kanye West splash out $6.3m on land

  Kim Kardashian and Kanye West splash out $6.3m on land Kim Kardashian and Kanye West have forked out $6.3 million on two acres of Californian land near to where her mother Kris Jenner owns a $12 million mansion, and her sister Kylie Jenner purchased some land for $3.25 million.The power couple have forked out the huge sum on an undeveloped home site in La Quinta's Madison Club community in California, and the land is said to be near to a $12 million mansion owned by her mother Kris Jenner, and close to a plot bought by her sister Kylie Jenner for $3.25 million last year.

Babs was the land speed record car built and driven by John Parry-Thomas. It was powered by a 27-litre Liberty aero-engine. Babs began as 'Chitty 4', one of Count Louis Zborowski's series of aero-engined cars named 'Chitty Bang Bang'.

FIA World Records are the fastest recognised official speeds achieved by any wheeled vehicle on land - excluding motorcycles, for which records are maintained by the Fédération Internationale de Motocyclisme (FIM). The Record Attempts are standardised over a fixed length course and averaged

Regolith has caused problems before

Peggy Whitson, an astronaut who lived in space for a total of 665 days, previously told Business Insider that the Apollo missions "had a lot of problems with dust."

"If we're going to spend long durations and build permanent habitats, we have to figure out how to handle that," Whitson said.

Brian O'Brien, a physicist who designed the regolith-measuring device that accompanied the Apollo 11 astronauts, told Wired that he suspects dust interfered with a seismometer and blocked solar cells on that mission.

Regolith measurements across the moon's surface could help future spacecraft avoid those problems.

"Some of the new engine types and the thrust levels that we will have - we really don't understand how it will stir up the different kinds of regolith in different locations on the moon," Alicia Dwyer Cianciolo, an aerospace engineer working on NASA's robotic moon missions, told The Atlantic in September.

A New Book About Sega Includes Incredibly Detailed Pop-up Paper Models Of Its Iconic Arcade Games

  A New Book About Sega Includes Incredibly Detailed Pop-up Paper Models Of Its Iconic Arcade Games With a Sonic the Hedgehog film setting records at the box office, now’s as good a time as any to reflect on Sega’s glory days in the ‘80s and ‘90s. But instead of focusing on consoles, a new book takes a deep dive on Sega’s iconic ride-on arcade machines and includes intricate pop-up paper models of six standouts. Besides that hyper-active blue hedgehog, Sega, which started life as a company called Service Games that sold coin-operated amusement machines to military bases in World War II, is probably best known for its consoles that went head to head with Nintendo, including the original Master System and the Genesis.

This article lists land speed records . There was a brief period in which Campbell held that record as a result of July 17. Nothing in this is a threat to Breedlove's legacy. It's merely a question of how we represent the history of the land speed record .

Below the 39 feet of fine dust, the Chang'e 4 rover also found a layer of coarse material full of rocks, followed by alternating layers of coarse and fine substances up to 40 meters (131 feet) deep.

Though China has not shared a specific timeline for the rest of the mission, the robots' goals on the moon's far side are to take photos of the barren landscape, study lunar geology, look for water ice, and scan the night sky for radio bursts.

Bonnie Zampino believes the burial ground in Harpers Ferry, W.V., may hold the remains of dozens or hundreds of Union soldiers who were killed in the Civil WarZampino, a case manager for recovering drug users who lives in the neighboring community of Bolivar, was used to encountering curiosities from the past on her hikes through Harpers Ferry, a town where history has left its imprint several times over. The village overlooking the Shenandoah and Potomac rivers is most famous for the failed anti-slavery raid led by abolitionist John Brown in 1859. It was also the site of a Civil War battle and hosted large contingents of Union and Confederate troops.
