Second day at camp: Lectures, Problems and Juggling

I'm pretty sure most students could not sleep last night excited to get involved in lectures and problem sets! After breakfast at 8am, the students rushed to their lecture rooms to get inspired by the lecturers. 

In the morning, May Meng (2014 IMO Manager) taught the Juniors some Algebra (Inequalities), and Chris Tuffley (2014 IMO Leader) extended the Senior's knowledge on how to count in combinatorics(Catalan Numbers).

May Meng inspiring the Juniors with an inspiring problem. Does anyone want to try? The problem is trying to prove the inequality on the second line.

Apparently that's the solution to the previous problem... Do you see how we get there?

After morning tea, the second set of lectures consisted of Junior Number Theory, taught by Peter Huxford (2014 IMO Contestant) and Senior Number Theory, taught by Dr Arkadii Slinko.

Woah what...???!!! Apparently the top list consists of primes less than 1000, and the next command outputs the smallest prime number greater than 765467898761...

Once the lectures have finished and everyone enjoyed their lunch, all the students (including Peter and I) headed to the dining hall to solve some challenging problems. Amazingly, one of the students, George Han, managed to claim to have solved all 8 problems!

Once the problem session finished and re-energized ourselves with beef and pork, Peter Bier (an Engineering lecturer in University of Auckland) visited to attempt to master(?) everyone in juggling. Personally, I have attended the camp for 4 years, and I still can't juggle...

Thanks to Peter Bier, most of us managed to master(?) the techniques of juggling.

After the evening activity, some boys gathered up in the lounge to play an intense game of Mafia, trying to accuse each other in order to save themselves.

A lot of things happened today, and I'm sure that students are looking forward to the schedule tomorrow, which includes my lectures (yes, the highlight of tomorrow) and paper-planes! 

Keep in touch to hear more maths camp stories.

P.S. I apologise for the poor resolution of the photos.
