Mr. Weinkauff's General Chemistry

These are the first "extra" Extra Credit questions:

    1. Describe the concept of the mole in Chemistry.

2. Who was Ada Lovelace? What is she known for?
3. What do you think about United States Patent 6,457,474?
4. What one thing do bullet-proof vests, fire escapes, windshield wipers and laser printers all have in common?
5. What do yogurt, beer, salami, and sauerkraut have in common?
    6. Pick an element and tell me everything you can about it (but don't just cut and paste from somebody else's work).

6. How did William Thomson get to be called "Lord Kelvin?"

When you write up answers to these questions, I want you to show me some thought and some real work. DO NOT just copy information out of a source and/or off the internet. Tell me what YOU think about this. Prove to me that you deserve the extra credit. Just copying (or cutting and pasting) a sentence or two from a web site or similar is not enough.
Another possibility is to answer the question:
"WHO IS ONE OF YOUR FAVORITE SCIENTISTS?"

    One of my favorite scientists was Richard Feynman.

    Richard Feynman (1918-1988) was a Nobel Prize winning physicist. He was involved in the Manhattan Project during the Second World War. He also taught for most of his career, and became known to many by his contributions to solving the space shuttle Challenger investigation. One of the notable things about Prof. Feynman was that he was able to relate Physics (and science in general) to all kinds of people of varying interests and backgrounds.

    He was perhaps one of the world's greatest theoretical physicists and thrived on outrageous adventure. His eyebrow-raising behavior once shocked a Princeton dean's wife to exclaim: "Surely you're joking, Mr. Feynman!" (A statement which later became the title to one of his books.) Feynman was surely the only person in history to solve the mystery of liquid helium, to be commissioned to paint a naked female toreador, and to crack the uncrackable safes guarding the atomic bomb's most critical secrets. He traded ideas with Einstein and Bohr, discussed gambling odds with Nick the Greek, and accompanied a ballet - on the bongo drums. His life story is a combustible mixture of high intelligence, unlimited curiosity, eternal skepticism, and raging chutzpah.
