Physics and Star Wars
To estimate the effects of the second Death Star, Minton looks into its mass. According to estimated data from some students of Lehigh University, the steel mass needed for building one would be around 770 kilograms times the mass cubed in weight. This would give the Death Star of about ten to the power of nineteen kilograms in mass. Using this data, Minton produces equations that lead him to conclude the fragments would hit the moons surface so hard causing craters almost four times the size of the Chicxulub crater in Mexico. This impact would cause a planetary firestorm and vaporize all lifeforms on the moon.
Maritime history of the United Kingdom
The "Titanic" and her sister ships "Olympic" and "Britannic" were built the White Star Line to outdo the "Mauritania" and "Lusitania" which belonged to the rival Cunard Line. "Titanic" was 269 m long and weight 46,000 tons. She was described as a luxury hotel at sea and as "unsinkable". She was fitted with a double bottom and 16 watertight compartments so that even if two were flooded she would not sink. "Titanic" departed from Southampton on 10 April 1912 on her maiden voyage to America. She called at Cherbourg and then Queenstown (now Cobh) before heading for New York City. Despite warnings of icebergs, she continued at on the night of 14 April. About midnight she hit an iceberg and five compartments started to flood. Two hours afterwards she sank. There were only enough lifeboats for half the passengers and 1,503 people perished. In 1985 her wreck was identified by sonar 4,000 m down and explored using a remotely operated vehicle (ROV). Some objects from the wreck have been recovered.
