8、A astronaut Edwin “Buzz” Aldrin, who famously became the second man to walk on the moon in July 1969, laid claim to a spaceflight first taking the first selfie in space during the Gemini XII mission in 1966.“For me, it needs to be digital to be selfie,” argues Jennifer Levasseur, who is in charge of
9、 the Smithsonian National Air and Space Museum. According to Levasseur, the concept of a selfie is directly linked to Internet culture and human desire to interact on social platforms. “The thing that makes a selfie is sharing it,” she says.Still, astronauts have been carrying cameras abroad space v
10、ehicles since the 1960s ,and theyve taken plenty of pictures of themselves along the way. Astronauts had to pull the film magazines out and leave their cameras behind when they returned to Earth because early space missions were restricted by a conservative weight limit on the return trip.A big chan
11、ge in space camera technology came after sad loss of the space shuttle Columbia who broke apart on its return to Earth in 2003. “Fearing that they would never be able to bring the film back from space and lose all that hard work celebrated the push for digital.” Levasseur says.Today astronauts can h
12、ave access to the Internet and social platforms in space and post true based selfies taken by digital cameras. Taking selfies and sharing them on social media is a way that astronauts in space can participate in the same activities people on Earth do every day. The first astronaut selfie that went v

16、 floods frequently, especially in the spring, making the streets so muddy that people, horses, and carts got stuck. An old joke that was popular at the time went something like this: A man is stuck up to his waist in a muddy Chicago street. Asked if he needs help, he replies, “No, thanks. Ive got a
17、good horse under me.”The city planner decided to build an underground drainage (排水) system, but there simply wasnt enough difference between the height of the ground level and the water level. The only two options were to lower the Chicago River or raise the city.An engineer named Ellis Chesbrough c
18、onvinced the city that it had no choice but to build the pipes above ground and then cover them with dirt. This raised the level of the citys streets by as much as 12 feet.This of course created a new problem: dirt practically buried the first floors of every building in Chicago. Building owners wer
19、e faced with a choice: either change the first floors of their buildings into basements, and the second stories into main floors, or hoist the entire buildings to meet the new street level. Small wood-frame buildings could be lifted fairly easily. But what about large, heavy structures like Tremont
20、Hotel, which was a six-story brick building?Thats where George Pullman came in. He had developed some house-moving skills successfully. To lift a big structure like the Tremont Hotel, Pullman would place thousands of jackscrews (螺旋千斤顶) beneath the buildings foundation. One man was assigned to operat
21、e each section of roughly 10 jackscrews. At Pullmans signal, each man turned his jackscrew the same amount at the same time, thereby raising the building slowly and evenly. Astonishingly, the Tremont Hotel stayed open during the entire operation, and many of its guests didnt even notice anything was
22、 happening.Some people like to say that every problem has a solution. But in Chicagos early history, every engineering solution seemed to create a new problem. Now that Chicagos waste water was draining efficiently into the Chicago River, the citys next step was to clean the polluted river.8. The au
