Our Location
The Pocono Mountains are in eastern Pennsylvania. Compared to the Himalayas, Alps, or Rockies, they're not really mountains. However, compared to the surrounding areas they are "mountains", especially when one has to drive up and down from our 2,000 ft. elevation on snow covered roads to get groceries............and we get a lot of snow.................
Dear Professor
Sy Yentz
Who invented the alarm clock?
Sciencerely, Wanda Lust
Dear Ms. Lust,
What an alarming question. It really ticks me off. Ha ha ha , Professor Sy Yentz has his timely sense of humor.
Levi Hutchins of Concord, New Hampshire, invented the alarm clock in 1787. His alarm clock, however, rang at only one time – 4 A.M. He invented the device so that he would never sleep past his usual waking time. He never patented or manufactured it.
The first modern alarm clock was made by Antoine Redier in 1847. It was a mechanical device. The electric alarm was not invented until 1890. The earliest mechanical clock was made in 725 B.C in China by Yi Xing and Liang Lingzan.
Sciencerely, Professor Sy Yentz
