Open House in Villa Ecureuil today!

A group of very nice teachers came to visit our Boarding House this afternoon. This is a tradition that started not too long ago, but we are all growing to love it! It is a chance for teachers to get to see the boarders in their environment and to understand how their days are organized..

It was a lovely afternoon indeed!

Here we are… taking care of the leftovers :)… Oops! The teachers had left!

Today is Fibonacci day!

Leonardo of Pisa, better known as Fibonacci, is responsible for the Fibonacci Sequence (or Fibonacci numbers) – a pattern of counting where each number is the sum of the previous two. As well as being prevalent in nature, this kind of system is used widely in computer data storage and processing.

The story began in Pisa, Italy in the year 1202. Leonardo Pisano Bigollo was a young man in his twenties, a member of an important trading family of Pisa. In his travels throughout the Middle East, he was captivated by the mathematical ideas that had come west from India through the Arabic countries. When he returned to Pisa he published these ideas in a book on mathematics called Liber Abaci, which became a landmark in Europe. Leonardo, who has since come to be known as Fibonacci, became the most celebrated mathematician of the Middle Ages. His book was a discourse on mathematical methods in commerce, but is now remembered mainly for two contributions, one obviously important at the time and one seemingly insignificant.

The important one: he brought to the attention of Europe the Hindu system for writing numbers. European tradesmen and scholars were still clinging to the use of the old Roman numerals; modern mathematics would have been impossible without this change to the Hindu system, which we call now Arabic notation, since it came west through Arabic lands.

The other: hidden away in a list of brain-teasers , Fibonacci posed the following question:

If a pair of rabbits is placed in an enclosed area, how many rabbits will be born there if we assume that every month a pair of rabbits produces another pair, and that rabbits begin to bear young two months after their birth?

This apparently innocent little question has as an answer a certain sequence of numbers, known now as the Fibonacci sequence, which has turned out to be one of the most interesting ever written down. It has been rediscovered in an astonishing variety of forms, in branches of mathematics way beyond simple arithmetic. Its method of development has led to far-reaching applications in mathematics and computer science.

But even more fascinating is the surprising appearance of Fibonacci numbers, and their relative ratios, in arenas far removed from the logical structure of mathematics: in Nature and in Art, in classical theories of beauty and proportion.

For keen mathematicians… The Fibonacci spyral is a real treat!

The first snow of the season :)

This is us today… and tomorrow! Well, let’s just say that it looks like winter has already arrived. Maybe it is just a “taste” of what the season will be like later… however, the change today was quite intense! But it is always beautiful to see those flakes falling, even if today they did not really stick to the ground.

Time for a cup of hot chocolate!

Happy birthday Vera!

Tonight we had a very good reason to celebrate: Vera turned 19! She really is THE senior student in the House 🙂

Many wishes from all of us in Villa Ecureuil!

TEDx event on Saturday!

I had the great chance to go to the TEDx event that was organized last Saturday with some of the CDL boarders – among whom, a great representation of the Ecureuil girls!

This TEDx event was organized by four prestigious Boarding Schools in Switzerland and, of course, CDL was one of them.

TEDx events are independently-organized events that follow the TED format. The basic and most essential mission they have is to discuss ideas worth spreading, and this is also what happened on Saturday. Four students and many other speakers went on stage to share their ideas, passions, strategies, feelings concerning the future (the title of this series of talks was “Next”), which is an extremely fascinating subject for all students and for everybody in general. I was really proud of the CDL student who gave a great speech, but also I found many of the talks extremely interesting, thought-provoking and fun.

Here are some pictures of this very beautiful day.
