A Brief History of Time by Stephen Hawking is worth reading, especially for those who love science, space, physics, and the universe (宇宙). About half of Hawking’s text is rather hard to understand, which must be the reason why he added pictures to newer editions. Some of the “abstract (抽象)” things are hard to imagine, so the pictures help you understand.

This book is based on theoretical physics (理论物理). Most people read the cover and think that it will be way over their heads, but it’s not. There are two ways to read it. You can read the chapter overviews, which are basic and you’ll still learn a lot, but it won’t be too difficult. Or, you can read the full details (细节) in each chapter, which is how you’ll learn the most.

This book makes references (参考) to other physicists, history, and current social and economic issues (问题), and explains how each of us is involved in the universe. Dr. Hawking also openly says “I think” about things. He gives his view on matters and shows the facts to help you see what you think the answer is, so it seems as if (好像) he was talking directly to you.

The reason why I love this book more than any other physics “text” is because Dr. Hawking wrote it like a novel. He’s telling a story, the story of the universe, and it’s just fun to read!

I always want to know how and why something is, and in this book Dr. Hawking always answers this question as best he can. If he can’t give you a definite answer, he’ll tell you what he thinks and help you develop your own opinion. I truly hope that you will read this unusual book.

In the last century, differnet natural disasters have robbed several cultural heritage(遗产) from us. On WeChat, some people say, “What a pity that we cannot see the damaged parts of the wonders anymore.” But people can see them in a new way---through a video game. In this game, the player can travel to one city after another and enter the buildings exactly like they are in reality, and see the wonders as they were before the fire.

Maybe digital technology(数字技术) could help protect cultural heritage better. This idea dates back to the 1990s and the necessary technology has continued to develop since then. By scanning(扫 描) the ancient buildings, building 3D models, as well as measuring everything, engineers can make a copy exactly as the real one.

As computers and smart phones are popular, the digital copy has great value. First, it allows tourists to feel the cultural heritage without touching them, which helps protect them. The virtual tour of Dunhuang Grottoes(敦煌石窟) is a good example of this as tourists can view the paintings without standing near them.

Second, it can make the cultural heritage more famous by spreading information about them through the internet. In 2000, a virtual tour of the Dunhuang Grottoes became very popular at the Hannover World Expo, which increased the number of foreign tourists visiting the site in the following years.

Last, it stores all the information of the cultural heritage. Even if the real ones are damaged one day, people can still know what they were like and can build a new one if wanted. Of course, however exact a model, it is not the real one.

Maybe we will have better technologies in the future, but the digital technology offers a practical way to protect cultural heritage at the moment.
