14th Asian Physics Olympiad (APhO) in Bogor, West Java, Indonesia

Lomba yang diadakan di kota bogor ini merupakan lomba yang sangat bergengsi. Biasanya soal-soal APhO lebih sulit dibandingkan dengan soal-soal IPhO (international physics Olympiad). Banyak para peraih medali perunggu APhO mendapat medali emas dalam IPhO. APhO tahun ini diikuti oleh 20 negara. Semoga tim Indonesia bisa berjaya.

Welcome Letter from Pak. Hendra Kwee, M.Sc., Ph.D.

It is an honor for us to host the 14th Asian Physics Olympiad (APhO) in May 5 - 13, 2013 in Bogor, West Java, Indonesia. We warmly welcome all delegations from Asian region to Indonesia. The event is sponsored by PT Telekomunikasi Indonesia Tbk (Telkom), the largest telecommunication service provider company in Indonesia, and organized by Surya Institute, a non profit foundation founded by Prof. Yohanes Surya, Ph.D. that actively promotes science and mathematics in Indonesia. Indonesia has organized the first APhO in the year 2000 in Karawaci, Banten, the 6th APhO in the year 2005 in Pekanbaru, Riau, and the 33rd International Physics Olympiad (IPhO) in the year 2002 in Nusa Dua, Bali. We are honored to be the host of APhO again.
