A Perfect Ten

I recently saw this posted by a friend; as an avid student of U.S. History myself, it had particular interest for me:

In 1825, the year before his death, Thomas Jefferson — the 3rd U.S. President and a Founding Father of the United States of America — was asked by a father to supply some words of wisdom to his young son, Thomas Jefferson Smith, who had recently been named after him. Jefferson graciously responded with a handwritten letter, at the end of which was the following 10-point list of advice for the youngster, titled, "A Decalogue of Canons for observation in practical life."

A Decalogue of Canons for observation in practical life.

1. Never put off till tomorrow what you can do to-day.
2. Never trouble another for what you can do yourself.
3. Never spend your money before you have it.
4. Never buy what you do not want, because it is cheap; it will be dear to you.
5. Pride costs us more than hunger, thirst and cold.
6. We never repent of having eaten too little.
7. Nothing is troublesome that we do willingly.
8. How much pain have cost us the evils which have never happened.
9. Take things always by their smooth handle.
10. When angry, count ten, before you speak; if very angry, an hundred.

Wichtigere: terbium, dysprosium, thulium, and lutetium, europium, cerium, and lanthanum.
Cerium is used in catalytic converters for diesel engines. Terbium is key for low-energy light-bulbs that cut power costs by 40pc. Neodymium is used in hard-disk drives, wind turbines, and the electric motors of hybrid cars. Fresh research in Tokyo shows that rare metals can cut friction on power lines, slashing leakage.
