謝謝老百的溫馨提醒，太讓我感動激動。
原來不喜歡生日，寧願如鴕鳥般把頭埋在沙子裏，
假裝忘記，自欺欺人，然後假裝自己還很年輕。。。
又老了365天， 加倍頭昏眼花心虛氣急手抖腳顫。
為了20100102／01022010臭美去了。

祝壇子裏的XDJM新年萬事如意，健康永駐。

There's something backward about this date

• 01-02-2010 can be read the same way in both directions.
  One math geek's really got its number.

Professor Aziz Inan has a passion for palindromes.
There will be 12 dates this century that can be read in two directions; today's is the second.

Some people are into cars. Some people dig the ocean. Aziz Inan, a professor of electrical engineering at the University of Portland in Oregon, loves numbers.

"I can relate to them," Inan said. "Each number has its own personality."

With this adoration in mind, consider today, Jan. 2, 2010. The day is a palindromic date, meaning the number can be read the same way in either direction: 01-02-2010.

There will be 12 palindromic days this century, Inan said, and today is the second. The first was 10-02-2001. (His complete list is here.)

A native of Istanbul, Inan creates math puzzles in his spare time. So it was a big day when he looked closely at his own name and saw a pattern. His first and last names are both vowel-consonant-vowel-same consonant -- and, if you write the names in all caps, switch the vowels and turn one set of consonants 90 degrees, both names are the same.

"I jumped in my chair," he said of the day two years ago when the connection hit him. "My parents had no idea."

Despite Inan's excitement about numbers, he dismisses the notion that mysticism and magic are connected to such dates.

He doesn't, for example, fear Dec. 21, 2012, the date the Mayan "Long Count" calendar marks as the end of a 5,126-year era. Some folks think the date portends a revolution or an apocalypse.

Jan. 2, 2010, and Dec. 21, 2012, he said, just happen to be really cool dates.
