The ancient Herculaneum scrolls (卷轴)are thought to contain works of important thinkers in ancient Greece. But the scrolls can't be unrolled (打开). Even a light wind threatens to reduce them to dust. The reason is that they were turned into carbon by a natural disaster in A.D. 79.
But now researchers from the University of Kentucky have found a way to look inside the scrolls without having to touch them. They first create a light that is 10 billion times brighter than the sun by taking advantage of a machine. Then they will use the light to go through the Herculaneum scrolls to study and finally read the words recorded on the scrolls. Researchers think it might take them six months to read the scrolls.
This isn't the first time researchers have tried to read the Herculaneum scrolls. Several years ago, scientists from the European Synchrotron Radiation Facility (ESRF) worked on uncovering the mystery using an X-ray beam 100 billion times brighter than anything used in a hospital, This didn't allow scientists to actually read the scrolls, but it allowed them to make one surprising discovery. The scrolls were written in metallic (金属的) ink, a writing technology that scientists didn't know existed at the time the scrolls were penned.
"For a long time, we thought our studies have let us know everything about the ancient ink used to write on scrolls. Now we find it's not the case. This shows that we should tell ourselves it may not be true when thinking we fully know something once some research is done," said Daniel Delattre, one of the study's authors.
The finding wasn't just a historical curiosity. To learn just how special these scrolls are, consider that the thinker Chrysippus in ancient Greece is said to have written over 700 works; but all are lost, with the exception of a few works found in the Herculaneum scrolls. In other words, it's possible that these scrolls represent the only existing complete works left by this great thinker. And who knows what other great works could exist in the scrolls?
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.

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.”

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#}
