《末世风云 2889》
Harry Potter and the Philosopher's Stone
A fantasy novel written by British author J.K Rowling.
It is the first novel in the Harry Potter series and Rowling's debut novel.
The Time Machine
The Time Machine is a science fiction novella by H.G. Wells, published in 1895 and written as a frame narrative. The work is generally credited with the popularisation of the concept of time travel by using a vehicle that allows an operator to travel forwards and backwards in time. The term “time machine”, coined by Wells, is now almost universally used to refer to such a vehicle.
The Machine Stops
The Machine Stops is a science fiction short story by E.M. Forster. The story, set in a world where almost all humans have lost the ability to live on the surface of Earth and each individual lives in isolation in a “cell” relying on a giant machine to provide their needs, predicted future technologies such as instant messaging and the Internet.
In the Year 2889
In the Year 2889 is a 1967 science fiction film about the aftermath of a future nuclear war. A nuclear war has wiped out most of Earth's population. The film follows a group of survivors who are holed up in a secluded valley and must protect themselves from rising radiation levels, mutants, and in some cases, each other.
