An anonymous reader writes: Simply amazing. From Slate: "Being buried alive is usually near the top of any worst-ways-to-die list. But how about being buried alive 100 feet below the ocean surface in a tiny pocket of air? For Harrison Okene, ... this nightmare scenario became a reality for nearly three grueling days. ... May 26 at about 4:30 a.m., when Okene got up to use the restroom. His ... tugboat ... swayed in the choppy Atlantic waters ... What caused the tugboat to capsize remains a mystery, ... Okene was thrown from the crew restroom as the ship turned over. Water streamed in and swept him through the vessel’s bowels until he found himself in the toilet of an officer’s cabin. ... For the next 60 hours, Okene—who was without food, water, or light—listened to the sounds of ocean creatures scavenging through the ship on his dead crewmates... When Maxim Umansky, a physicist at the Lawrence Livermore National Laboratory in California, read about Okene’s miraculous rescue, his interest was piqued. “For a physics question, it’s an interesting problem,” said Umansky. “Of course, I’m also glad the man survived and happy with the ending of his story.” Umansky began conducting his own calculations to quantify the factors responsible for Okene’s survival. He also posed a question to a physics Web forum: How large does a bubble have to be to sustain a person with breathable air? "
