What happened?

"What happened?" asked the hospital visitor to the heavily bandaged man sitting up in bed.
"Well, I went down to Alton towers and decided to take a ride on the Loch Ness Monster. As we came up to the top of the highest loop, I noticed a little sign by the side of the track. I tried to read it, but it was very small and I couldn't make it out. I was so curious that I decided to go round again, but we went by so quickly that I couldn't see what the sign said.
"By now, I was determined to read that sign, so I went round a third time. As we reached the top, I stood up in the car to get a better view."
"And did you manage to see what the sign said this time?" asked the visitor.
"Yes," he said sheepishly, "Remain seated at all times!"

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.
