100% Polar bear

One afternoon in the Arctic, a father polar bear and his son polar bear were sitting in the snow. The son polar bear turned to his father and asked, "Dad, am I 100% polar bear?"

"Of course, son, you're 100% polar bear."

A few minutes pass, and the son polar bear turns to his father again and says, "Dad, tell me the truth. I can take it. Am I 100% polar bear? No brown bear or panda bear or grizzly bear?"

"Son, I'm 100% polar bear and your mother is 100% polar bear, so you're certainly 100% polar bear."

A few more minutes pass, and the son polar bear again turns to his father and says, "Dad, don't think your sparing my feelings if it's not true. I really need to know... am I really 100% polar bear?"

Distressed by this continued questioning, the father polar bear finally asked his son, "Why do you keep asking if you're 100% polar bear?"

"Because I'm freezing to death out here!"

Metric System

In 1960, the fourth legal definition of the metre was made to be 1,650,763.73 wavelengths in vacuum of the orange-red light radiation of the krypton-86 atom (transition between levels 2p10 and 5d5). It was adopted at the 11th meeting of the Conférence Générale des Poids et Mesures (CGPM), which also specified the seven basic units of the SI system. It was superceded by a fifth definition of the metre on 20 Oct 1983, based on the speed of light. The definition in terms of wavelengths of the kryton spectral line wasthen100 times more accurate than the previous third legal definition adopted in 1889. (The third legal definition on 28 Sep 1889, was based on the distance between two reference markson the International prototype metre bar, made of platinum-iridium, (90% Pt, 10% Ir), cross section X, at a 0 °C temperature.)«[Image: Krypton-86 gas excited by high-frequency oscillator, in a vessel cooled to the temperature of liquid nitrogen to produce precise monochromatic radiation.
