GAMES LEWIS CARROLL

[For the summer issue of the journal At Bâbord . Answers in the journal.]

The movie Alice in Wonderland will probably awareness of Lewis Carroll to a new generation. But many people are still unaware that Carroll's name was Charles Lutwidge Dodgson actually (1832-1898), he was reverend and he taught mathematics at Christ Church College, Oxford.

Besides his writings for children, Dodgson also leaves many articles and books of mathematics, a discipline that must be said, however, it has not contributed as much as literature.

But we never change and in his mathematical writings, Carroll has often found this fantasy in his writings for children, and conversely, in the latter, it comes to math games.

The first mathematical game that offers just from a book for children: The Hunting of the Snark .

1. Count to 3

In this book, Beaver is convinced that one thing he will say three times for that reason alone will automatically true. It's fine, but it is still necessary to count up to 3! And the unfortunate beaver can not. Fortunately, a Butcher will teach him, but a curious way. It proceeds like this: Let


three to one digit more convenient to ask
is the object on which we must reason
We will add in September then ten. The result
We multiply by a thousand less than eight. There.

As you can see, we then divide the whole
For nine hundred ninety-two, exactly
We then subtract seventeen from this brand
And the answer is good, very well

Boucher How did he do it every time to find 3?

2. The doublets

Carroll was so fond of games and puzzles that he composed many, gathered in two books.

One of those games, famous, is called Doublets Carroll.

You are asked to leave a word of letters X and succeed, in not changing each time a single letter (this change generates a new word) to another given word at the beginning of the game
Let
the sort of UAE WINE - changing water into wine. We will

:

WATER
VAU
VAN
WINE

Here there are only three letters and the exercise was easy. But you can change a man into a monkey? Or put on a RED LIP?

Several responses are possible, the best is obviously shorter. Next time I will publish the best I have received.

3. Carroll called him the following riddle an "enigma of dessert." She is famous and rightly so: it is superb.

is how he formulated it:

"Take two cups, one containing 50 teaspoons of cognac, the remaining 50 tablespoons of pure water. Take the first a spoonful of brandy; transfer it, without spilling in the second cup and stir. Then, take a spoonful of the mixture and transfer it, without spilling in the first cup.
My question is: if you look at the whole operation, he was transferred over the first cup of brandy in the second, or more water from the second to first? "
