Apologies are in order.  This site has not been updated since November 27, 1999 due to ongoing server problems.  Errors  have recently been rectified and it is hoped that continued updates will take place from now on.  My sincerest appreciation to Mr. Kevin Xiong, Computer Services Department, Toronto Catholic District School Board.  Thanks Kevin for your  help in bringing us on-line again. 

 I would also like to thank Eric Liu (class of '99) for his ongoing contribution to the Brebeuf  Science Department.

5. Leonardo da Vinci Contest

6/8/99

Contgratulations to Francisco Kibedi for placing in the 80th percentile in the Leonardo da Vinci Science competition sponsored by the Faculty of Applied Science and Engineering, University of Toronto.  The number of students who wrote the exam this year was 2519. 

6. Brebeuf Crystal comes in Second and WINS spot for International Competition 

5/26/99 

Eight  students  competed for the top award in the first International Crystal Chemistry Competition, to be held in Glascow Scotland (August 4-13/99), during the XVIIIth International Union of Crystallography Congress.  In late April, the best crystals from each Local Area were sent for judging to  the National Level (Guelph Ontario, the week of May 3, 1999).  The top crystals  from the National Level will  now be sent to Scotland for the International Competition.

Placements for National Level are:

Brampton 1- 25.6 g, was 1st overall and 11th in quality
Toronto 2 ( Brebeuf ) 93.4 g was 2nd overall and 14th  in quality

The quality (Q) of the crystal is judged on a scale of 1 to 10, with 10 representing a perfect crystal. The following factors will be considered in judging quality: 
a) match/mismatch with crystal type (out of 2) 
b) presence/absence of occlusions (out of 2) 
c) intact/broken edges (out of 2)  
d) well formed/misformed faces (out of 2) 
e) clarity/muddiness (out of 2) 

Total Quality Q = x.xx (out of 10) 

The total score is then determined as follows:  Total Score = [log (M+1)] x Q x 10 (M=mass of crystal in grams) 
The logarithm of the mass is chosen so that large poor quality crystals don't swamp out smaller good quality crystals. 
The value 1 is added to the mass so that crystals weighing less than 1 g get a positive score.  The crystal with the highest score is the winning crystal.  

Many thanks to:  Andy Au, Kevin Chang, Jason Cheng, Rupert Chi Cheung Chan, Jin Soo Kang, Nick Galatianos, Godfrey Lee and David Tran. 

Good Luck Team! 

7.  Honourable Mention for James Li 

7/19/99

Congratulations are in order for James Li,  who received an Honourable Mention at the Canada-Wide Science Fair in Edmonton Alberta.

8.  Brebeuf captures 3rd place in York University Science Olympics

1999 Complete Olympic Results

The team of: Rupert Chi Cheung Chan,  Ross Tam,  Brian Drakopulos,  Alan Luck,  Marco Vane, Jim Ng,  Nick Galatianos,  Ewen Chan,  Eric Liu, Paul Jara and Arthur Nip captured a Third Place Finish (from a total of 45 registered school teams)  at the York University Science Olympics on Friday May 14, 1999. 

This years science-related team  events included: 

Compounds - Teams competed directly against each other by making up formulae of chemical compounds in "Scrabble" TM fashion from a pack of cards, each of which had the name of an element or radical on it.  
Rupert Chi Cheung Chan,  Ross Tam,  Brian Drakopulos 

Bio-Steeplechase - Teams competed to answer multiple choice questions located at a series of obstacles or hurdles. The first team that  answered all the questions correctly was the winner. Team membersattempted to answer the questions in relay fashion. There were 4 ‘hurdles' and  4 questions at each hurdle.  
Brian Drakopulos,  Alan Luck,  Marco Vane, Jim Ng 

Catapult (2nd place finish) - Teams  fired water-filled balloons from a giant catapult made by stretching rubber tubing between ‘football' goalposts. Targets were placed at various distances downrange on the field.  
Jim Ng,  Nick Galatianos 

Fermi Questions (2nd place finish)- Teams were required to make estimates in answer to questions such as "How much chemical energy (in Joules) is derived from all the food consumed by Canadians annually?"  
Ewen Chan, Eric Liu, Brian Drakopulos, Alan Luck, Marco Vane 

Water Rocket - Teams launched a 2 litre plastic pop bottle, partially filled with water under pressure produced with a bicycle pump. Longest duration of flight wins.  
Eric Liu (with some last minute help from team members) 

WWW Scavenger Hunt - Teams  embarked on a scavenger hunt on the web. Given a set of clues, 
they  followed links on the world wide web to some final destination. Along the way they had the opportunity to collect special ‘Easter eggs' (bonus points) that were used in computing their score.   Paul Jara and Arthur Nip  

Special thanks to Professor Kieth Aldridge of the Physics Department at York University for making this an enjoyable day for all. 

9.  Brebeuf gets top honours at the Metropolitan Toronto Region  Science Fair 

Congratulations to James Li who placed FIRST in his division at the Metropolitan Toronto Region Science Fair held at the University of Toronto April 15, 1999.  James has been chosen to represent the Toronto Region at the Canada-Wide Science Fair, to be held in Edmonton Alberta, from May 15-23 1999.  We wish him all the best at this level of competition. 

Special recognition also goes to Richard Li, who placed SECOND in the same Science Fair.  He received the Canadian Mathematical Society Prize for his work on "The Divisibility Test For All Odd Numbers".
