On October 31st, 2009, Chinese famous scientist Qian Xuesen, died in Beijing when he was 98 years old. He is famous as “the country's father of space technology and king of rocketry”.

    Qian was born in 1911 in Hangzhou. He left for the United States after winning a scholarship to graduate school in 1936. He studied at the Massachusetts Institute of Technology and later at the California Institute of Technology.

    Qian began his career in the US and was regarded as one of the brightest minds in the new field of aeronautics（航空学) before returning to China in 1955.

    After he returned, Qian set up the first missile（导弹）and rocket research institute（学院) of China. The institute later helped start Chinese space program. He led the development of China's first nuclear-armed ballistic missile (弹道导弹) and worked on its first satellite.

    He retired in the year before Chinese manned space program was launched in 1992. But his research formed the basis（形成基础）for the Long March CZ -2F rocket that carried astronaut Yang Liwei into orbit in 2003.

    In August, 2009, Chinese Premier Wen Jiabao visited Qian and praised him for devoting his life to Chinese defense technologies. Qian told him, “I'm trying to live to be 100 years old”.

SM Card Cutter

    Did you know you can cut a regular size phone SIM card to a smaller size SM card and it will still work?This tool will help you do it.Just stick a SIM card in it,press it down like a stapler(订书机).A perfectly shaped smaller SIM is there.I've used it many times when swapping SIMs from one phone to another.

Profi Cheese Slicer

    Uses a thin wire to slice up to medium-hard cheeses in four inch sections.

    I may own every cheese slicer ever made.I prefer a wire type cheese cutter so I can cut slices that work well on a piece of bread and sandwich.

    This cheese slicer is great for both tasks.It even has adjustable tension on the two cutting wires.A point of information: I did break a wire cutting a very hard piece of cheese with black pepper.Good news,the wire is replaceable,and I was able to purchase new wires to fix it.Maybe best to use on softer cheeses.Lessons learned.But, highly recommended for every other use except for those extremely hard cheeses.

Ash Bucket(桶子）

Bucket with lid keeps your fireplace(壁炉）clear of ashes.

    I purchased this ash bucket recommended by my friend and have found it invaluable.Previously I had an old bucket that got left outside and usually filled up with rain and became a mess to clean.This ash bucket has a raised bottom and thermal insulation(隔热层）to prevent any accidental hot coals in your ash to damage your floor or cause a fire.You can store this bucket indoors since the lid is nice and tight.

    It may not come as a surprise but the world as a whole is getting richer. Some people have more disposable(可支配的) income to spend on luxuries such as holidays, cars, TVs and smartphones. Recent data has shown that the number of people living in extreme poverty(贫穷) has halved in recent decades. So should we celebrate the fact that more of us now have a better standard of living?

    Maybe not. Whilst the gap between rich and poor in some countries is narrowing, there is still a lot of inequality in other places-some people have a lot of money and opportunities and others don't. A recent report by Oxfam and Credit Suisse revealed how divided many of us are when it comes to wealth. A lot of the money in the world is in the hands of very few people. In fact, 48% of global wealth is owned by the richest 1% of the population.

    But some countries are attempting to reduce this inequality and make the poor, less poor. According to David Bryer from Oxfam, Brazil has been taking "some really sensible measures-measures around having more progressive(逐步发展的) tax, around investing in a higher minimum wage and investing in central public services." Having a higher minimum wage, can help people eat better and seek a better education. And more people with more money buy more things-and factories can produce more. In turn, a factory which produces more will need more workers. So, more jobs are created.

    Other wealthy individuals are doing their bit to help reduce inequality. Bill Gates, the founder of Microsoft, earned a lot of money from his company but when he retired, he and his wife Melinda, created a foundation to help the poor. He thinks that rich people should, of course, pay their taxes but he also advises that they should all "look at taking their wealth and being philanthropic, both in their own country and to help the global poorest."

    Bill Gates feels that giving money to help poor people is "fulfilling". But if other super-rich people don't want to experience this fulfilment then, according to Oxfam, very soon the wealthiest 1% will soon own more money than the rest of the world's population.

    If you want to travel from Xi'an to Chengdu by train, it will take about 16 hours. But starting this month, the new Xi'an-Chengdu high-speed railway will shorten this travel time to three hours.

    The 643-kilometer line is China's first high-speed railway to run through the Qinling Mountains, which form a natural boundary (分界线) between China's north and south. With a speed of 250 km per hour, it's also the first mountain-heavy train line to provide a 4G network. Along the way, the train passes through two areas for rare (稀有) wild animals — one for pandas and the other for crested ibises (朱鹮).

    To reduce the railway's influence on the animals, workers and experts have designed and built the railway to be environmentally friendly. There were 345 wild pandas living in the Qinling Mountains. China currently has 1,864 wild pandas in total, according to the Xinhua News Agency.

    To avoid disturbing the pandas, the railway was designed to run through tunnels (隧道) within the area. Protective shields (防护屏) are placed near the entrance of each tunnel to stop animals from going in.

    To protect the thousands of crested ibises that fly near one part of the railway, protective nets have been set up to make sure the birds will not fly into a train.

    The nets are about 32 km long and 4 meters high. Experts tested different shapes and materials for building the nets before making their final choice.

    Doctors say you had better use it before you lose it. The more you sit each day, the more chance you have of getting sick.

    Richard Rosenkranz of Kansas State University was among the researchers. He said people who sat for long periods were at great risk of diseases when compared with those who sat less. He said that was especially true for some chronic (慢性的) diseases.

    Richard Rosenkranz studied the relationship between sitting and chronic diseases in middle-aged Australian men. He worked with researchers from the University of Western Sydney. They examined the health records of more than 63,000 men from New South Wales. The men were between the ages of 45 and 65. The men reported about what diseases they had, or did not have. And they kept record of the amount of time each day that they sat.

    The study also showed that exercising every morning for 30minutes did not reduce the health risk if you spend the next eight hours sitting at the desk. Mr. Rosenkranz said it was important to make sure you exercise. But he said it was also important to find ways not to sit so much during the day.

    Many jobs today require sitting and working at the desk all day. James Levine works at the Mayo Clinic in the United Sates. He suggests working while standing at high table some of the time instead of sitting at a desk. Dr. Levine also suggests standing while using the telephone or eating. Or he advises walking with the people you work with for an on-foot meeting. And he notes that if you spend more time on your feet, you may have muscle activity that helps burn fats and sugars in your body.
