Here are some easy tips for getting to sleep. They can help you deal with tension, stress and anxiety, and enjoy a good night sleep. Not every one of these tips alone will get you to sleep, but a few of them at least should be useful.

Get some physical exercise during the day. Even 15 minutes a day of exercise (at least half an hour before going to bed, so your body will have a chance to slow down) will give your body the activity and oxygen(氧) it needs to help you relax more and sleep better.

We often praise the world of science.

It explains the world and makes our lives easier with technology. One of the most exciting fields in science is artificial intelligence (人工智能 AI). This is an area where scientists are working on creating machines that think like humans.

However, one of the most famous scientists has a very dark warning for us about this type of technology.

“The development of artificial intelligence could spell the end of the human race,” said Professor Stephen Hawking to the BBC.

Hawking is a well-known British scientist and writer of bestselling science book A Brief History of Time. This warning came after he used the machine particularly made for him. As Hawking suffers from a serious disease called ALS, he needs an AI computer to communicate. The computer learns how Hawking thinks and suggests the words he may want to use next.

This is a basic type of AI, which is very useful, yet Hawking is frightened of the possibility of creating technology that can match or surpass human intelligence. And it’s easy to imagine how terrible things may be. Many TV shows and films display big, killer machines that are far cleverer than us. “Humans can’t compete because they are limited by slow biological evolution (生物进化),” said Hawking.

In what direction do you think AI is heading? Should we be hopeful or fearful?
