The lecture for this class is about the city of Pompeii. A natural disaster occurred there almost 2000 years ago.
Today many rich peopl e who live in large metropolitan areas such as Beijing, Paris and New York leave the city in the summer. They go to the mountains or to the seashore to escape the city noise and h i t.
2,000 years ago, wealthy Romans did the same left the city of Rome in the summer. Many of these wealthy Romans spent their summers in the city of Pompeii, a beautiful city, located on the Bay of Naples.
In the summer of the year 79 ., a young Roman boy who later became a very famous Roman historian was visiting his uncle in P.. The boy’s name was Pliny the Younger. One day Pliny was looking up at the sky. He saw a frightening sight. It was a very large dark cloud. This black cloud rose high into the sky. What Pliny saw was the eruption of the volcano called Mount and ash flew through the air. The city of P . was at the foot of Mt. V.. When the volcano first erupted, many peopl e were able to get out of the city and to escape death. In fact, 18,000 people escaped the terribl e disaster. Unfortunately, there was not enough time for everyone to escape. More than 2,000 people died. These unlucky people were buried alive und er the volcanic eruption lasted for about 3 days. When the eruption was over, P . was buried under 20 feet of vol canic rock and ash. The city of P . was forgotten for almost 1,700 years.
In the year of 1748 an Italian farmer was digging on his farm. As he was digging, he uncovered a part of a wall of the ancient city of P.. Soon archaeologists began to dig in the area. As time went by, much of the ancient city of P. was uncovered. Today tourists come from all over the worl d to see the ruins of the famous city of Pompeii.

Let's talk about the physics involved in a ride on a roller coaster. I'm sure many of you have taken a ride on a roll er coaster. A simpl e
roll er coaster consists of a frame with a track on it. The track is very much like a train track, this track goes over a series of hills and around curves. It foll ows a path that ends at the same place it started.
A train of cars travels around on this track, very fast. The cars have two sets of wheels . One set of wheels rolls on top of the track, and the others set of wheels rolls bel ow the track. The wheels bel ow the track keep the fast moving cars from coming off the track, roller coaster cars as you probably know d on't have any motors or engines. Instead, a chain pulls the cars up the first, tallest and steepy staff hill, this is how the ride begins. Then, at the top of the hill the chain comes off the cars and gravity takes over. gravity pushes the cars d own the other side of the hill. the taller and steeper the first hill is, the faster the ride will be. And the farther the cars will travel. as the cars rolled d ownhill they gained speed. the cars have enough speed and energy to send them up the next hill. as the cars near the top of the second hill they begin to sl ow down. but then, the cars reached the top of that hill, and start d own the other sid e. gravity again pushes them toward the ground. this process repeats on each hale. Okay, so let's go over this process again. first, the cars are pulled by a chain up the first highest hill. then they go d own a very steep slope, at this point, there is enough energy to pull the cars up and over the next hill. when they reached the bottom of that hill, there is enough energy to climb the next hill, the roller coaster cars l ose energy as the ride continues. so, the hills have to be smaller toward the end of the track, finally we roll to a stop on ground level right where we began.
I’d like to talk to you today about Steve Jobs. Jobs was someone who changed the worl d because he changed the way peopl e act every single day.
