Abstract
Let's imagine that a business man is waiting to board at the Kennedy airport. He has bought a cup of Starbucks coffee, then he opens his laptop, thanks to the wireless access, within a few seconds, he connects to the internet. He checks his mailbox. Then he calls his colleague who is in Paris. After that, he goes to the Google's website and types "Japan earthquake". In a few more seconds, he gets a lot of information on the earthquake which happened thousands of miles away. After the boarding announcement, he gets on the plane. 7 hours later, he arrives at Paris which is roughly 3600 miles away from New York.
All these seem so plain and ordinary for us today. However, if we trace back to 100 years ago, these things would be unbelievable for people at that time.
