About the Lecturer

Yingfeng Zhang is an advocate for generalist education in science and technology for teenagers, college students and technology enthusiasts.  He founded QHOW Technology in Toronto in 2019, an educational hub that equips participants with knowledge of technology, business, and hands-on experience in product design and development.  Yingfeng holds a Master’s degree in Software Engineering from Shandong University, China.  Before he moved to Canada three years ago, he had worked as a science and technology educator  and consultant for over a decade, training software developer employees on cutting-edge technologies and scientific ideas, and guiding university  students to develop software products, and  helping them write and publish technology books.  He is an Honourable Contributor (2015) on Zhihu, the Chinese equivalent of Quora.  He has written more than 100 answers in the fields of education, mathematics, science, and history. He has around 170K followers on Zhihu, and his articles were saved by readers for more than 400K times.  Currently, Yingfeng is writing a book on the history of Calculus  which origin and evolution dates back to ancient Egypt and ancient Greece.

About Lecture

In this lecture series, we will travel with Yingfeng through thousands of years to understand the history and ideas of mathematics, touch the profound thoughts behind it, and see how human beings have use it to solve problems in their lives.

Lecture 1: Astronomy

  • Ancient Greek myths and constellations
  • Why do people look up at the stars and why invent constellations?
  • What knowledge do people get from the stars?
  • How did astronomy inspire ancient philosophers?  How have their thoughts profoundly affected human civilization?

Lecture 2: Geometry

  • The Ancient Egyptians and their pyramid
  • What did the Egyptians do with Geometry?
  • How did the Pythagorean Law become the Pythagorean Theorem?
  • Why did the Greeks think it was very important to use Compass andstraightedge?
  • How did the Geometry of Ancient Greece lay the foundation of modern society?

When the pandemic is over, Yingfeng would like to lead field trips into the  wildness.  We would get to listen to the stories of astronomy under the starry sky, recognize the constellation, observe the meteor shower, and/or learn to measure their latitude and time.  We could also go to an open field, and measure the land like an Ancient Egyptian tax collector. We would reproduce the common geometric theorem discovery process, and see how the Pythagorean theorem was discovered and how it was applied in practice.

Lecture 2 (Geometry): Friday May 29, 2020 8:00-9:30 P.M. Eastern Time
