Stephen Hawking was born in Oxford, England on 8th January,1942. He was a world-famous British physicist. He also wrote a children’s book with his daughter. He said the book would be “a bit like Harry Potter” but without the magic and explain the wonders of the universe.

He was probably the world’s most famous scientist after Albert Einstein. He was an expert on black holes. He had put his whole life into digging into the beginning (and the end) of the universe. “My goal is simple,” he once said. “It is to completely understand the universe, why it is as it is and why it is there at all.”

He had a bad illness that kept him from moving or talking. For a period of time, he had no way to communicate except by blinking(眨眼).

He often sat on a wheelchair with a computer by his side. To communicate with others, he moved two fingers to control the computer’s mouse. He selected his words from the screen, which were then spoken by a voice synthesizer(合成器).

“I have had the disease for most of my life,” he once said. “Yet it has not stopped me from being successful at my work.”

Although he was such a disabled man, he made great achievements. He had received many awards for his work over the years. These include winning the Albert Einstein Award.

All over the world the need for more laptops and computers increases each year. Networks have been part of our life. Probably everyone with a portable device (移动设备) has once logged on to a public WiFi network without paying for it, while they are having a coffee, on a train, in a shopping mall or at a hotel. However, is this kind of public WiFi network safe?

Some networks are better protected than others because encryption (加密) methods are used. Therefore, they are safer than others. But a survey in 2015 showed that more than 950 million records were not protected, including addresses, emails, birth dales, phone numbers, passwords and so on. These open WiFi networks are really not safe, because it is very easy for hackers to break into the operating system and get people's private information.

Most smartphones and laptops, by themselves, search and connect to WiFi networks. They usually prefer a network with a connection that has been used before. Hackers' devices are able to record these searches and look like the trusted WiFi networks. When these smartphones and laptops log on to the networks which are not real, hackers can easily steal their private information.

So next time, when we want to use our laptops or our smartphones in public places which offer free WiFi networks,please think it twice or take safe measures before using them.
