6. QUOTES & POINTS TO PONDER

 

"Intuition is the aristocratic way of discovery, rigour the plebian way." - H.V.D. Hodge, mathematician

 

"There are no extra pieces in the universe. Everyone is here because he or she has a place to fill, and every piece must fit itself into the big jigsaw puzzle." - Lewis Carroll, English mathematician and writer, 1832-1898.

 

"The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom." - Isaac Asimov, Russian-born American author and biochemist, 1920-1992.

 

"Intuition comes to us much earlier and with much less outside influence than formal arguments which we cannot really understand unless we have reached a relatively high level of logical experience and sophistication. Therefore, I think that in teaching high school age youngsters we should emphasize intuitive insight more than, and long before, deductive reasoning."— George Polya (1887-1985) in (1981). Mathematical discovery: On Understanding, Learning, and Teaching Problem Solving, (Combined Edition), New York, John Wiley & Sons, p. 128.

 

 

7. HUMOUR IN MATH & SCIENCE

 

Law of Mechanical Repair - After your hands become coated with grease, your nose will begin to itch and you'll need the toilet.

 

Law of the Alibi - If you tell the boss you were late for work because you had a flat tyre, the very next morning you will have a flat tyre.

 

Variation Law - If you change lines (or traffic lanes), the one you were in will always move faster than the one you are in now (works every time).

 

Archimedes Law of the Bath - When the body is fully immersed in water, the telephone rings.

 

Law of Close Encounters -The probability of meeting someone you know increases dramatically when you are with someone you don't want to be seen with.

A popular legend tells of a beginning student of geometry asking Euclid, "What shall I get by learning these things?" Euclid remained silent and called his slave, saying, "Give him a coin, since he must make gain out of what he learns."
