Any mistake made in the printing of a stamp raises its value to stamp collectors. A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value.

The mistake was made more than a hundred years ago in the British colony of Mauritius, a small island in the Indian Ocean. In 1847 an order for stamps was sent to a London printer-Mauritius was to become the fourth country in the world to issue stamps.

Before the order was filled and delivered, a ball was planned at Mauritius’ Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the design for the stamps. He accidentally inscribed the words “Post Office” instead of “Post Paid” on the several hundred stamps that he printed.

Today there are only twenty-six of these misprinted stamps left fourteen One Penny Orange-Reds and twelve Two Penny Blues. Because of the Two Penny Blue’s rareness and age, collectors have paid as much as ＄16 800 for it.

What is the color of the universe? Astronomers did not answer this question until two months ago. This was when two American astronomers reported on their study of all the light in the universe. They said that the universe would appear to the human eye to be a light greenish color, called turquoise(青绿色). Karl Glazebrook and Ivan Baldry of Johns Hopkins University in Baltimore, Maryland, reported their findings in January. They presented research at a meeting of the American Astronomical Society. They said that finding the color of the universe was not part of their more serious scientific research. They did it for fun.
However, earlier this month, the scientists admitted to making a mistake. They said their finding was much more colorful than it should have been. They now say the light from our universe is closer to white. It is more like a milky or creamy white color.
The scientists gave a number to each of the colors of the different star systems. Then they added the numbers together and found the average measurement. The scientists used this average to identify the color of the universe. They said it was a very pretty light green or turquoise color. They called it “cosmic (宇宙的) spectrum (光谱) green.” Many newspapers and television stations reported their finding.
Other scientists and color engineers attempted to reproduce the result. Mark Fairchild of the Rochester Institute of Technology in New York was the first person to identify a mistake. He discovered a mistake in the computer software program used by the Johns Hopkins scientists.
When the mistake was corrected, the results changed. The new color of the universe is much less colorful. It is very close to white. The scientists apologized for the mistake. They are now working with the Rochester Institute of Technology to produce more images regarding the color of the universe.

Cole Bettles had been rejected by a number of universities when he received an e-mail from the University of California, San Diego, last month, congratulating him on his admission and inviting him to tour the campus. His mother booked a hotel in San Diego, and the 18-year-old Ojai high school senior arranged for his grandfather, uncle and other family members to meet them at the campus for lunch during the Saturday tour.
“They were like ‘Oh my God, that’s so awesome （棒的）’， ” Bettles said. Right before he got in bed, he checked his e-mail one last time and found another message saying the school had made a mistake and his application had been denied.
In fact, all 28, 000 students turned away from UC San Diego, in one of the toughest college entrance seasons on record, had received the same incorrect message. The students’ hopes had been raised and then dashed （破灭） in a cruel twist that shows the danger of instant communications in the Internet age.
UCSD admissions director Mae Brown called it an “administrative error” but refused to say who had made the mistake, or if those responsible would be disciplined （受训）。
The e-mail, which began, “We’re thrilled that you’ve been admitted to UC San Diego, and we’re showcasing （展示） our beautiful campus on Admit Day, ” was sent to the full 46, 000 students who had applied, instead of just the 18, 000 who got in, Brown said.
The error was discovered almost immediately by her staff, who sent an apology within hours.
“It was really thrilling for a few hours; now he’s crushed （压垮）， ” said Cole’s mother, Tracy Bettles. “It’s really tough on them.”
The admissions director said she was in the office on Monday until midnight answering e-mails and phone calls from disappointed students and their parents. She said she took full responsibility for the error. “We accessed the wrong database. We recognize the incredible pain receiving this false encouragement caused. It was not our intent.”
