The Mona Lisa is the famous Leonardo da Vinci painting of a woman with a mysterious smile. This week, the painting gave up a secret.
Scientists used X-rays to examine the chemical organization of an extremely small part of the more than 500-year-old painting. The researchers discovered a technique Leonardo used in the work. A team in France and Britain discovered an oil paint used for the Mona Lisa was a special, new chemical mixture. It suggests that the Italian artist may have been in an experimental mood when he set to work on the painting early in the 16th century.
"He was someone who loved to experiment, and each of his paintings is completely different technically," said Victor Gonzalez. He is the study's lead writer. "In this case, it's interesting to see that indeed there is a specific technique for the ground layer of the Mona Lisa," he said in an interview with The Associated Press. Specifically, the researchers found a rare compound, plumbonacrite (水蛭石), in Leonardo's first layer of paint. The discovery, Gonzalez said, proved that da Vinci most likely used lead oxide to thicken and help dry his paint.
The scientists looked into its atomic structure using X-rays in a synchrotron (同步加速器). The machine moves particles at close to the speed of light, permitting researchers to look deeper into the paint structure. "Plumbonacrite is really a fingerprint of his recipe," Gonzalez said. "It's the first time we can actually chemically prove it."
Dutch artist Rembrandt may have used a similar mixture when he was painting in the 17th century. Gonzalez and other researchers have found plumbonacrite in his work, too. "It also tells us that those recipes were passed on for centuries," Gonzalez said. "It was a very good recipe."
But the Mona Lisa and additional works by Leonardo still have other secrets to tell. "There are plenty, plenty more things to discover," Gonzalez said. "What we are saying is just a little brick more in the knowledge."
Do you have any problem with time? Start doing these and you will see the difference.
●Write it down
Don't rely on your memory to keep track of every little detail. {#blank#}1{#/blank#} Write down the things you need to do in a small notebook, or use online tool to create and update your “to-do” list.
●{#blank#}2{#/blank#}
Working for long periods without a break can waste your time. It is more efficient to work or study for a shorter period of time, take a break, and then go back to work. You may get more done in tow focused 45-minute sessions.
● One thing at a time
{#blank#}3{#/blank#} Do one thing at a time, and do it well. As the Chinese proverb says, “One cannot manage too many affairs. Like pumpkins in the water, one pops up while you try to hold down the other.”
● Schedule email time
On your cell phone you get a notification every time someone sends you an email. If so, you have to check your email many, many times a day. {#blank#}4{#/blank#} Schedule time to check your email. It doesn't matter when.
● Choose to say “No”.
It's easy to become overwhelmed if we say “yes” to everything. Think about the task before you commit to it. Do you need to do it? Can someone else do it? Avoid saying “yes” to every request. {#blank#}5{#/blank#}
● Keep a goal journal
Write down your goals in a journal and evaluate them regularly. Mark your progress for each goal. Be sure you take the necessary step to achieve your goals.
A. Make a list first B. Don't skip the breaks C. Turn that notification off D. Memory is not always accurate E. Don't forget to focus on your task F. This takes time away from more important tasks G. Every time we switch from one task to another, we lose focus |
