The year 3700, Earth is far too hot for any human to call it home. On this planet at least, man is nothing more than a memory--if there is anything left to remember the "wise man". But what about our wisdom--will any of it survive us?

    The conventional answer is no. Knowledge requires a knower, and there will be no knowing minds around then. But if information survives, perhaps in books or hard drives, maybe the knowledge isn't quite dead but dormant(休眠), ready to become alive with the help of other minds that develop over time or come to visit Earth in the distant future.

    At first sight, that seems to be reasonable: after all, we have done similar things with past knowledge. For example, we saved an ancient computer from a ship destroyed at sea off the southern coast of Greece, and succeeded in finding the meaning of Egyptian hieroglyphics(象形文字). Careful work can bring previously lost wisdom back to life.

    However, the key point is that there is a certain cultural continuity with those ancient times that allows us to reason and make progress in the dark: we know we are dealing with the legacy(遗产)of other humans. Without that link, the survival of objects and raw data doesn't guarantee the survival of knowledge. And a lack of continuity in language with any future intelligence would be a barrier. Knowledge is closely connected with language. When a language dies out, we can lose systems of reasoning that they contain. If that's lost, then it can't be recovered.

    All this means that other minds might not be able to fully make human knowledge alive when we are gone. It is better to concentrate on not dying out in the first place.

    When he was young, Louis Armstrong was taking what was called “Creole jazz”, which was also called dance music, and combining it with trumpeter (小号手) Buddy Bolden, to create what would eventually become today's jazz.

    Armstrong accomplished that with almost no formal training. He received little training before he was placed in the New Orleans Colored Waif's Home at the age of 12, after a run-in (小争执) with the police. The punishment turned out to be a mixed blessing, for he also had the opportunity to play in a real band.

    While at the Waif's, Armstrong also got the chance to hear some of the city's finest musicians. Cornetist Freddie Keppard performed in a nearby club. So did trumpeter and bandleader, King Joe Oliver, who took the boy under his wing and taught him how to read music and work on his playing technique.

    When Oliver left for Chicago, Armstrong chose to stay in New Orleans and work with some of the other top musicians of the day. In Chicago, King Oliver offered him a place in his band in 1922. It became Armstrong's biggest challenge yet — the band had no parts written for trumpet, so he was forced to listen to King Oliver and improvise (即兴创作).

    Soon, Armstrong's undeniable talent was getting notice. Even classically trained musicians would come to hear the incredible sounds this young man created.

    Lil Hardin, the bands piano player and the future Mrs. Armstrong, explains that Oliver kept Armstrong in the second trumpet-chair so that Oliver would still be “King”. Hardin convinced him to leave the band.

    Armstrong moved to New York City in 1924 to join Fletcher Henderson's band and then flew solo. In 1925, Armstrong put together the Hot Five, expanding his popularity even more. Armstrong recorded his first composition, Cornet Chop Suey, one of the most copied jazz solos of all time. This monumental 1928 recording blends (混合) artistry, endurance and showmanship that has rarely, if ever, been matched in Jazz.

    Fire fighting is a serious matter. Knowing what to do during a fire can save people's lives. It is important to know the ways you can use and show them to everyone else in the family, such as stairways and emergency exits, but not elevators.

    From the lower floors of buildings, escape through windows is possible. Learn the best way to get out from a window with the least chance of serious injury.

    The second floor window is usually not very high from the ground. An average person, hanging by the fingertips will have a drop of about 6 feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way down than to stay in a burning building.

    Windows are also useful when you are waiting for help. Be sure to keep the door closed before opening the window. Otherwise, smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked(漏)into the room.

    On the second or third floor, the best windows for escape are those which open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement might end in injury. Bushes and trees can help you to have a soft landing.
