### Dutch Science Quiz

Usually, on 31-Dec, one might thinks of a bang of the ending year, a great achievement, values that created great opportunities for the new year ....

I am a senior member of Wilmott. I like the spirited discussion about topics in economy, quant finance, mathematics, technology, programming, but also off topics ...

Motivated by a Dutch senior member, an open team of "Wilmotters" decided to participate the 2012 Dutch Science Quiz as a group.

And we won the group prize - a private tour to the ESA Space Expo.

What is exciting about this? I found the process effective and efficient: none of the team members was assigned as leader, or co-ordinator... but -- or because? -- the result was found quickly and straight forward. All 15 answers are correct.

I answered the questions independently based on my own knowledge and without mining information (as if I stood as a candidate in a live show) before the team started - 5 wrong answers.

The wisdom of teams ... (and the availability of great resources) make the difference.

Here are the Winners

And here is the final Show with candidates, the answers and the rationale .. enjoy (but maybe you want to answer ... first?)
