Lost boots

There was a little boy in kindergarten. At the end of one cold winter day, when all the other children were leaving, the teacher found him crying, so she asked him what was wrong.

He sobbed, "I can't find my boots."

The teacher looked around the classroom and saw a pair of boots. "Are these yours?"

"No, they're not mine," said the little boy, shaking his head.

The teacher and the boy searched all over the classroom for his boots.

Finally, the teacher gave up, "Are you SURE those boots are not yours?"

"I'm sure," the boy sobbed, "mine had snow on them."

Carrier invents air conditioner

In 1902, Willis Haviland Carrier completed drawings for what came to be recognized as the world's first scientific air conditioning system. In 1901, he started working in research and development for Buffalo Forge Co., a leading manufacturer of fan heating equipment. Shortly, he was assigned to solve a problem for a printing plant where humidity control was necessary for paper handling in the machinery. The system he designed with cooling coils was installed at the Sackett and Wilhelms Co. in Brooklyn in 1902, though it was retrofitted to an existing hot-blast heating system instead of being properly designed from scratch as a total system. However, Carrier went on to improve on his invention, and began the air-conditioning industry.
