It encouraged us to visit Quora. com, the online question and answer community, to find out how users get the most out of every tank of gas.

    Light makes right

    Alex Elderfield noted that excess weight prevents an engine from burning fuel efficiently. "Only carry what is essential in your car, clean out any junk or necessary items otherwise you are paying for the fuel to cart these from place to place," he wrote.

    Driving smoothly — that is, not mashing the gas and then slamming the brakes later down the road — was a fixture of many responses. Quora user Clint Law agreed on that advice, who wrote, "Every little bit of kinetic energy that your brakes lose, your engine burned in fuel to build up." Overbraking should consequently be viewed as wasted acceleration. "That's really what kills your fuel economy," he argued.

    Keep the pressure up

    Keeping the recommended tire pressure for your car was another mantra among Quora users. Marlyn Rosent said she checked her tire pressure every time she filled up her SUV. Quora user Doug Dingus checks his tire pressure every weekend. “Less tire contact means reduced rubbing, requiring less fuel,” he said.

    Air conditioning or windows

    Though the summer heat get many drivers to roll up the windows and turn on the air conditioning, some people argued that running the A/C wastes too much gas. In between were many shades of grey.

    Achilleas Vortselas said it would depend largely on a car's speed. He wrote that as a general rule, people should drive with the windows down around the city and turn the air conditioning on when hitting the highway, where a car's aerodynamic(空气动力的) characteristics would be influenced by opened windows.

    More seriously minded people, however, said to travel as much as possible with windows up and the A/C off. Eddie Xue gets by with just a wisp of outside air. “Use the fan and open your windows every now and then at lower speeds," he wrote.

    People often say that there is nothing in the world that can be as great as a mother's love. Some mother expressions mean just that. The phrase "mother lode" comes from mining. It means the place where the largest amount of gold can be found. But now, the term "mother lode" means a rich supply of anything. For example, you might say, "She just graduated from college and struck the mother lode with her new job!"

    When we call something "the mother of all", this means it is the biggest or best of something. Here is an example: "We are going to throw the mother of all parties this weekend. So you have to come!"

    Naturally, the word "mother" can be used to mean to give birth, even to something you cannot touch, such as an idea or wisdom. The saying "necessity is the mother of invention" means that when people really need to do something, they will find a way to do it. And "experience is the mother of wisdom" means that people learn from what happens to them.

    You might think all expressions about mothers are sweet and loving. Not so. A boy who is "tied to his mother's apron strings(围裙带)" is controlled by his mother. We can also call him a "mama's boy". Both of these terms are even more insulting(侮辱人的) if you are talking about a man, not a young boy. It can be a huge mistake for a woman to marry a "mama's boy" who is still "tied to his mother's apron strings".

    A show about mothers would not be complete without talking about the very popular but mysterious "Mother Goose". The short poems and songs that "Mother Goose" wrote are a part of growing up in the United States. Real or not, you could say "Mother Goose" is the mother of all nursery rhyme(童谣) writers.

    Dr. Nancy Roman, born in 1925, who was celebrated as a pioneer for female scientists and had advanced the launch of the Hubble Space Telescope, died on Dec 25, 2018.

    When Nancy Roman asked for permission to take a second algebra (代数)course in high school,a teacher demanded to know "what lady would take mathematics instead of Latin". In college, a professor admitted that he often tried to prevent women from majoring in physics but Nancy stuck to it. And after receiving Doctor's degree in astronomy. , she found a professional home at NASA(美国宇航局)In 1959, Dr. Roman became the first chief of astronomy at NASA. headquarters, a role that made her one of the agency's first female leaders.

    Dr Roman spent much of her career helping develop, fund and promote technology that would help scientists see more clearly beyond Earths atmosphere. But her most well-known work was perhaps leading to design the Hubble Space Telescope the first major telescope to be sent into space for the purpose of gathering photographs and data from the universe. She was, therefore, named as "the mother of Hubble".

    "She made it possible to get the early telescope up into space to learn what needed to be learned," said science historian Bob Zimmerman: and her hard-nosed nature helped get the telescope built.

    The telescope did not launch until 1990, a little more than a decade after Dr Roman retired, but when it did, its photographs of the universe thrilled the world.  I am glad, "she once told Science, "I ignored the people who told me that I could not be an astronomer. "

    In 1973, I was teaching elementary school. Each day, 27 kids entered "The Thinking Laboratory." That was the name students voted for after deciding that "Room 104" was too dull.

    Freddy was an average student, but not an average person. He had the rare balance of fun and compassion(同情). He would laugh the loudest over fun and be the saddest over anyone's misfortune.

    Before the school year ended, I gave the kids a special gift, T-shirts with the words "Verbs Are Your friends" on them. I had advised the kids that while verbs may seem dull, most of the fun things they do throughout their lives will be verbs.

     Through the years, Pd run into former students who would provide updates on old classmates. I learned that Freddy did several jobs after his graduation from high school and remained the same caring person I met forty years before. Once, while working overnight at a store, he let a homeless man sleep in his truck. Another time, he lent a friend money to buy a house.

    Just last year, I was conducting a workshop when someone knocked at the classroom door. A woman excused the interruption and handed me an envelope. I stopped teaching and opened it up. Inside were the "Verbs" shirt and a note from Freddy's mother. "Freddy passed away on Thanksgiving. He wanted you to have this."

    I told the story to the class. As sad as it was, I couldn't help smiling. Although Freddy was taken from us, we all took something from Freddy.
