There is bomb on top of a computer; around the computer are a hairbrush, keys, phone and a cup. When the explosion comes, what item destroyed first?
Who makes it, has no need of it. Who buys it, has no use for it. Who uses it can neither see nor feel it. What is it?

Victor Moritz Goldschmidt

Died 20 Mar 1947 at age 59 (born 27 Jan 1888). Swiss-Norwegian geochemist, mineralogist and petrologist who established a theoretical background for geochemistry (which in the previous century had been limited to the collection of data on the accessible earth's crust, waters and atmosphere.) Goldschmidt investigated the major and minor elements in minerals, and sought to explain their distribution as a result of cosmic origins. He invented crystal chemistry, whereby he attempted to complete a record of mineral crystal forms, and to link the variations of those forms to the physical and chemical conditions under which they were formed. In this pursuit, he both improved existing instruments and invented new ones. He is regarded as the founder of modern geochemistry.«

An avid duck hunter was in the...

An avid duck hunter was in the market for a new bird dog. His search ended when he found a dog that could actually walk on water to retrieve a duck. Shocked by his find, he was sure none of his friends would ever believe him.
He decided to try to break the news to a friend of his, the eternal pessimist who refused to be impressed with anything. This, surely, would impress him. He invited him to hunt with him and his new dog.
As they waited by the shore, a flock of ducks flew by. They fired, and a duck fell. The dog responded and jumped into the water. The dog, however, did not sink but instead walked across the water to retrieve the bird, never getting more than his paws wet. This continued all day long; each time a duck fell, the dog walked across the surface of the water to retrieve it.
The pessimist watched carefully, saw everything, but did not say a single word.
On the drive home the hunter asked his friend, "Did you notice anything unusual about my new dog?"
"I sure did," responded the pessimist. "He can't swim."
