The secret of my success

Grandpa was celebrating his 100th birthday and everybody complimented him on how athletic and well-preserved he appeared.

"Gentlemen, I will tell you the secret of my success," he cackled. "I have been in the open air day after day for some 75 years now."

The celebrants were impressed and asked how he managed to keep up his rigorous fitness regime.

"Well, you see my wife and I were married 75 years ago. On our wedding night, we made a solemn pledge. Whenever we had a fight, the one who was proved wrong would go outside and take a walk."

Lowest temperature ever

In 1994, the National Institute of Standards and Technology (NIST) issued a press release that physicists there recently cooled atoms to 700 nanokelvins, the coldest temperature ever recorded for matter. NIST scientists chilled a cloud of cesium atoms very close to absolute zero using lasers to catch the atoms in an optical lattice. The atoms reached 700 nanokelvins, or 700 billionths of a degree above absolute zero. Zero kelvin (-273ºC), or absolute zero, is the temperature at which atomic thermal motion would cease. Since the late 1970s, physicists have sought to use lasers to cool atoms closer to absolute zero, primarily for improving atomic timekeeping, certain experimental measurements and lithography processes for the semiconductor industry.
