According to the latest AIME qualification cutoff after AMC, more than 30 students from SHSID High School successfully qualified for AIME 2021. Congratulations to these students! Let's wish for them the best results in the coming challenge on March 19th.

Mathematics is not only a stage for these competitors to strut their stuff, but also a paradise for all students to enjoy the beauty and fun of mathematics. On Pi Day 2021, the SHSID high school mathematics department had its interdisciplinary celebration, making students feel the unique charm and ubiquity of mathematics. Math Pies were baked in an unusual and creative way this year.

Mini-Program Pie

The STEM Doge members have been working on the mini-program of the preliminary round of the Math Knockout. Anya, a STEM Doge member, said: "Since math serves as the foundation for science, we reckoned that our activity could be more interdisciplinary. That is why we incorporated the knowledge and skills from computer science in our preliminary round to create a mini-program that displays math problems in an engaging form." Yusuke, one of the developers, thinks: "As a developer of the mini-program, I felt the responsibility to ensure a complete and bug-free experience for users when navigating through the program. We had to consider users of different grades, on other devices and operating systems, etc. Debugging the mini-program was also exhausting, but, in the end, the effort was worth it because we were able to present math as interactive and enjoyable."

The math knockout qualifier started in the early hours of March 14 and ends at midnight on March 19. There are five levels related to mathematics in the preliminary round. The students will qualify for the next round if their cumulative score exceeds a specific grade. March 29 to April 9 is the time of group PK and the final rounds.

Lecture Pie

From March 15 (Monday) to March 19 (Friday), many students took advantage of the lunch break to bring peer lectures to collide mathematics with various application software such as Geogebra, R, python, Latex, SPSS, etc. During this period, there will also be exciting lectures about the game 24-point playing strategy.

Game Pie

At noon on March 15, students actively participated in several geometry-related games on campus. The game "The Fifth Great Invention – Mortise & Tenon" made students have a good time. While improving their spatial imagination, they could experience the traditional Chinese mortise and tenon structure, design carpentry work, and resonate with the exquisite conventional Chinese crafts and the application of mathematics. Students were also fascinated by the games "Shadowmatic" and "Xsection."

Cos Pie

On March 15, all senior high-school students played roles in math class. Some students felt the unique history of mathematics and the typical development process of mathematics with other disciplines by acting the highlight moments of mathematicians or interdisciplinary scientists. The 9th and 10th graders mainly focused on Euclid, Descartes, Pythagoras, Archimedes, Galois, Lagrange, Alan Turing, and John von Neumann. The 11th and 12th graders acted more about Isaac Newton, Leibniz, Brook Taylor and Riemann, de Moivre, Euler, Gauss, and the Bernoulli family. Some students were imitating their math classroom, pretending to give math lectures, or acting as students engaged in math class. The math teachers also celebrated Pi Day in their way, posing as a giant letter π, and hoping to encourage the students to love and learn more math. There is no limit to mathematics nor its application.
