James Cameron is one of the best directors in the world. His famous Titanic, which was first showed in 1997, was made into 3D movie this year------the 100 anniversary of Titanic being sunk.
The movie Titanic is close to the real accident happened on April 14th, 1912 and there’s a lot of physics involved in the movie. We have to admit that James Cameron really spent plenty of time on the causation of the accident. ①physics side note: Pressure (√)

At the beginning of the movie, there is a group of people who want to find the invaluable “Heart of the Ocean”. They used submarine to get 3821 meters under the sea level. The absolute pressure on the submarine equals to the atmosphere pressure plus the pressure given by water. But the pressure given by water is so big that we can even ignore the P0 Pa =ρsea water*g*h

And the force on the window of submarine is F=P*A. So the force is 3.9*107N. The answer is almost the same as what the “boss” said in the movie when they were about to get into Titanic. ②physics side note: internal energy and work (√)

In the film, Mr. Eames suggested Captain Smith letting Titanic go with the full speed. And what they did in the film is asking the workers to add more coals to run the machines, which I believe are diesel engine or steam engine.

According to the first law of Thermodynamics we learned in Chapter 15, we knew that internal energy equals heat minus work done by the engine. (ΔU=Q-Wby) The work done by the engines made Titanic go forward. This is an energy transfer from heat to mechanic energy. And because the efficiency (e) of the certain engines won’t change and e=W/Q, so add more heat into the engine can produce more work. So the workers opened more engines and put more coals into them to run the engines with more heat.

③ physics side note: heat + wave (√)

In the movie, the night of April 13th, 1912, was extraordinarily cold but the ocean was peaceful. The sailors...
