Dear Leaders and Contestants
On behalf of the Organizing Committee of the 21st Asian Physics Olympiad , I am honored to welcome you to the 21st APhO.
This APhO was planned to be held in 2020 but postponed to 2021due to the Covid-19 pandemics. Although the Coronavirus is very much under control in Taiwan, the online competition of the 21st Physic Olympiad is still a safer option to proceed with. I believe it will be a great challenge for all leaders, contestants and the Organizing Committee. I, however, am very confident that this competition will be as successful as before and perhaps create a new modality for future competitions. I have high hope on every one of you. The International Science Olympiad competitions are vital to the overall development of human beings. This is the place where tomorrow’s greatest science talents meet and share their insights and experience. The International Science Olympiad competitions is the incubator where we breed the next big breakthrough in science. National Taiwan Normal University was founded almost 100 years ago on a similar mission: To cultivate teachers so they can guide young talents to realize their full potential. I am proud to say that our University has a long history of remarkable achievements in science education and research. We are also a leader in the cultivation of scientific talents in Taiwan.
NTNU is a strong support and a member of the International Science Olympiad community. In addition to this event, we have hosted several international Olympia competitions in mathematics, physics and chemistry, earth science, biology, informatics and one International Junior Science Olympiad. Over the years, thousands of talented students all over the world have visited our campus, and we are proud to be able to work with these wonderful students in facilitating their quest into the world of science.
I look forward to your participation in the first online Asian Physics Olympiad. I wish this Olympiad a great success, all of you a memorable experience in the competition and good luck to all the constants.
