Who Would Have Thunk It...
One day there were nine planets. The next day, there were only eight. Poor Pluto...demoted from planet-status by the rewriting of a single definition.
So what or who is the next victim of a powerful definition? Some options:
Ah, definitions! Pluto is still number nine in my book...and will remain in that place until someone finds enough money to rewrite the book.
- Maybe 2 will be demoted as a prime number. It is the only even candidate presently, so why complicate things. Just define a prime number to be an odd positive integer (>1) whose only factors are 1 and itself.
- Maybe 1 will become a prime number, since most students want it to be one anyway. Just define a prime number to be a positive integer divisible only by 1 and itself.
- Maybe the world can decide what the definition of a trapazoid is. Is it necessary that at least two of the opposing sides be non-parallel? A clever writer of a new definition can solve the problem.
- Maybe a number can be divided by zero...since 99.99999....% of the world's students already think it can! All we need is a new definition...and then let those who teach higher mathematics figure out how to circumvent the new problems created.
