The Titan submersible plunged thousands of feet down the forbidding depths of the North Atlantic Ocean in search of the Titanic wreck site when it imploded, killing all five on board. OceanGate came under heavy scrutiny as a result of the disaster — an almost unheard-of occurrence in the submersible industry. But after the Titan didn’t return at its scheduled time, the Polar Prince contacted the Coast Guard. The suit remains ongoing, and a former OceanGate engineering director, Tony Nissen, named as a defendant, is expected to appear Monday at the Coast Guard hearing. “The Titan submersible did not just go down with its inventor — it went down with paying passengers.”

Erin Schaff/The New York TimesForce of Ship Collision Was on the Scale of a Rocket LaunchThe container ship Dali appeared to move sluggishly before striking the Francis Scott Key Bridge in Baltimore on Tuesday. Experts disagreed on whether it was reasonable for any bridge pier to withstand a direct collision with a massive container ship. F = ma force mass acceleration F = ma force mass accelerationOur first task, and a major source of uncertainty, was finding those numbers. F= (100,000 to 195,000 metric tons) × (7.8 mph - 2.5 mph) / 38 seconds mass acceleration F= (100,000 to 195,000 metric tons) × (7.8 mph - 2.5 mph) / 38 seconds mass acceleration For the actual calculation, we used metric units. We tried one more method: using a formula to calculate the ship collision force published by the American Association of State Highway and Transportation Officials, the industry organization that publishes bridge safety standards.

☆ Netflix's hit sci-fi series '3 Body Problem' is based on a real math problem that is so complex it's impossible to solve

AdvertisementWhile Netflix's "3 Body Problem" is a science-fiction show, its name comes from a real math problem that's puzzled scientists since the late 1600s. In physics, the three-body problem refers to the motion of three bodies trapped in each other's gravitational grip — like a three-star system. The three-body problem is over 300 years oldThe three-body problem dates back to Isaac Newton, who published his "Principia" in 1687. Can you solve the three-body problem? Though the three-body problem is considered mathematically unsolvable, there are solutions to specific scenarios.

"This is a centuries-old problem," Shane Ross, an aerospace and ocean engineering professor at Virginia Tech, told Business Insider. Alpha Centauri is the closest star system to EarthThe three-body system in the story is based on a real neighboring star system called Alpha Centauri. At about 4 light-years from Earth, it's the closest star system to our own and contains three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri, which has two planets orbiting around it.

☆ Titanic submersible: A robot is combing the sea floor for debris from the implosion as a multinational investigation begins

The US Coast Guard has convened a Marine Board of Investigation to probe the implosion – the “highest level of investigation the Coast Guard conducts,” US Coast Guard chief investigator Capt. Military experts found debris from the ill-fated submersible about 1,600 feet from the bow of the Titanic on Thursday, the US Coast Guard previously said. “This case has been extremely complex, involving a coordinated international, interagency and private sector response in an unforgiving and difficult to access region of the ocean,” US Coast Guard Rear Adm. John Mauger, the First Coast Guard District commander, said Sunday. The Coast Guard announced the vessel suffered a “catastrophic implosion,” killing everyone on board. Pelagic's remotely operated vehicle Odysseus 6 is lifted out of the ocean after searching for debris from the Titan submersible on June 22, 2023.

☆ Voice recordings and data from the mother ship that carried the Titanic-bound submersible before it imploded will be examined, investigators say

“The content of those voice recordings could be useful in our investigation,” Fox said. Communications between the submersible and its mother ship will also likely be scrutinized. The ship could communicate with the submersible by text messages, and it’s required to communicate every 15 minutes, according to the archived website of OceanGate Expeditions. The vehicles will work to map out the vessel’s debris field, which is more than 2 miles deep in the North Atlantic, Mauger said. When asked for comment about Stanley’s email, a spokesman for OceanGate told CNN they were unable to provide any additional information at this time.

The discovery led the US Coast Guard to announce the ship likely imploded, killing all five passengers aboard. The Odysseus 6 discovered debris from the Titan submersible about 1,600 feet from the wreckage of the Titanic on Thursday, according to the US Coast Guard. All five are presumed dead after the “catastrophic implosion” of the submersible, according to the US Coast Guard. On Friday, Coast Guard Rear Adm. John Mauger said, “I don’t have an answer for prospects at this time” when asked about recovering remains. A Coast Guard official said Thursday that authorities are discussing how an investigation would unfold since the implosion took place in international waters.

More examples of the image, which says GPS data can help “tip the election/s to their preferred candidates” (without identifying who “they” are), are viewable (here), (here). But GPS accuracy is degraded by satellite signal blockage (due to buildings, bridges and trees), indoor and underground use, as well as signals reflected off buildings, among other factors (here). There is no mention of using online surveillance via GPS and geolocation to verify who voted, contrary to the social media claims. For example, by monitoring the sites an individual visits or the posts they create on social media, Google “can have some idea on” voter preferences.
