New for 2012 is the Cumulative Leader Board. After January's 'warm-up' challenge, as well as having an Honours Board for each month, there will also be a Cumulative Leader Board for the five months February to June. Points will be awarded depending on position in each month's Honours Board.
Ten points will be awarded for each puzzle correctly answered each month. A person successfully completing the entry level puzzle will receive 10 points, those completing the entry and copper puzzles will receive 20 points etc. Everyone completing all five puzzles in a given month will be awarded at least 50 points, however bonus points are awarded to the first 1000 people to complete the challenge each month. The number of bonus points awarded decreases exponentially as the number of people who have completed the challenge increases.
In 2012 the number of points awarded each month will be
calculated using the equation:
Points awarded = 50 + 500 exp(-0.006 (rank order -1) )
Thus the first person to finish all five puzzles in a given month will have rank order 1 and will be awarded 550 points, the second person to finish all five puzzles will have rank order 2 and be awarded 547.01 points, and so on. The cumulative leader board will display the sum of the scores achieved each month.
At the end of the competition prizes will be awarded
- The three highest scoring participants worldwide who are under the age of 18 on 1st July 2012.
- The highest scoring participant under the age of 18 on 1st July 2012 from each country that has at least 50 participants scoring 100 points or more.
- The three highest scoring participants worldwide who are at or over the age of 18 on 1st July 2012.
- The highest scoring participant over the age of 18 on 1st July 2012 from each country that has at least 50 participants scoring 100 points or more.
The prize is a specially designed C3L6 crystal trophy. It features a laser-etched, three-dimensional, electron probability density plot of one of the hydrogen atomic orbitals. An example is shown to the right. We'll leave you to work out which orbital this one features!
The list of prize winners will be published on the C3L6 website on 1st July 2012. The decision of the awarding committee is final.
