Miss Gogers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them,“Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from across the street, which of you would hear what I said earlier, my brother or you and for what reason?”

　Tom at once answered,“Your brother. Because electricity travaels faster than sound waves.”“That’s every good,”Miss Gogers answered; but then one of the girls raised her hand, and Miss Gogers said.“Yes, Kate.”

　“I disagree,”Kate said.“Your brother would hear you earlier because when it’s 11 o’clock here it’s only 8 o’clock in Los Angeles.”

Tom Brennan was working in a Philadelphia office building when he noticed a black bag. The bag contained a book.

　　This chance discovery ended a 12-day search by the Library Company of Philadelphia for a historical treasure-a 120-page diary kept 190 years ago by Deborah Logan,” a woman who knew everybody in her day,” James Green ,the librarian told the magazine American Libraries.

　　Most of the diary is a record of big events in Philadelphia. It also includes a description of British soldiers burning Washington D.C. in the war of 1812. She describes President James Madison on horseback as "perfectly shaking with fear “during the troubled days. George Washington, she writes, mistook her for the wife of a French man and praised her excellent English.

　　The adventure of the lost book began on September 4 when Cory Luxmoore arrived from England to deliver the diary of his ancestor(祖先)to the Library Company, which he and his wife considered to be the best home for the diary.

　　Green told American Libraries he had the diary in his possession “ about five minutes” when Luxmoore took it back because he had promised to show it to one other person. On returning to his hotel after showing the precious book to Green, Luxmoore was shocked to realize that he had left it in the taxi.

　　Without any delay, Green began calling every taxi company in the city, with no luck, "I've felt sick since then," Luxmoore told reporters.According to Green, no one has yet learned how the diary came to the office building .

   Tom Brennan received a reward(奖励)of 1,000, Philadelphia gained another treasure for its history , and Luxmoore told reporters, "It's wonderful news. I'm on high".
