Math Olympiad Series: Solving Problems in Geometry Insights and Strategies

Dr Hang and Mr Wang have authored a Mathematical Olympiad book: Solving Problems in Geometry Insights and Strategies. It will be officially launched on 1 June 2017 at the Math Teachers' Conference at National Institute of Education. The book will be sold at a promotional price of S$25 (softcover) at the event.

This book is suitable for any reader with elementary geometrical knowledge at the lower secondary level. Each chapter includes sufficient scaffolding and is comprehensive enough for the purpose of self-study. Readers who complete the chapters on the basic theorems and techniques would acquire a good foundation in geometry and may attempt to solve many geometrical problems in various mathematical competitions. Meanwhile, experienced contestants in Mathematical Olympiad competitions will find a large collection of problems pitched at competitions at the international level, with opportunities to practise and sharpen their problem-solving skills in geometry.

You may also order the book online from here, at S$34 (softcover) with S$4 shipping.

Acceptance into European Summer Program on Rationality (ESPR)

I have blogged about the ESPR here. Lim Li has been accepted into this year's ESPR.


Dear Lim Li,

Congratulations! We are pleased to offer you admission to ESPR. We think we have an incredible group of students this year, and we are excited to have you join us.

Let us know if you have any questions, or if you just want to talk to get a better sense of the program before making your decision. We would appreciate if you would let us know whether or not you are planning to attend ESPR as soon as you’ve decided; if we haven’t heard back from you by May 17, 2017, we’ll offer your spot to another student. If you are coming, we’ll send you more details once your participation is confirmed.

ESPR will run from August 18-31, 2017, at Kings College in London. Food, room, and board are covered for all students. We would prefer that students able to cover their travel expenses do so, but if you would like to be considered for a travel scholarship, then send us an email and we'll figure it out.

Best wishes,
-The ESPR team


From ESPR website:

The European Summer Program on Rationality (ESPR) is an immersive summer workshop for mathematically talented students from around the globe with a desire to understand our world (16-19 years old as of August 17, 2017). 

Past participants include International Math Olympiad gold medalists, web entrepreneurs, artistically and scientifically gifted individuals, and many others. ESPR is the successor of the acclaimed EuroSPARC program, and is modeled after the SPARC summer camp. 

The curriculum includes a variety of topics. Past classes have covered topics ranging from mathematical logic, understanding what a DNA sequence is, and dives into philosophy and psychology. The learning is extended with guest speakers from a variety of cutting edge fields. 

But the ultimate goal of our program is to show how rigorous, quantitative skills can be applied outside the classroom, in all pursuits. How can we understand our behavior? How can we think more clearly to achieve our goals?
