On the evening of December 13th, Cai Wenjun, associate professor of School of Mathematical Sciences, who is studying on computational mathematics, was invited by the alliance of students majoring in mathematics of the Honors College to give a lecture on the topic of "Rambling Computational Mathematics".
Professor Cai started with the integral that students are familiar with. He pointed that not every definite integral can be solved for its specific value. At this time, students need to find out an approximate value of it. Then, Professor Cai said that although Euler's method of integration is useful in definite integrals and differential equations, it has its limitations. Based on this, he gave a follow-up explanation on the subject of computational mathematics. Finally, Professor Cai introduced other applications of computational mathematics, including applications in astrophysics, and ended the lecture with a video which simulates the solar system moving through the universe.
Professor Cai’s humorous lecture style won the students’ praise.
