扭曲的宇宙：用數學來理解空間

It's fun to learn abut space, but sometimes it can be hard to understand how we know things and why they happen. For example, how do we know we live in a spiral galaxy? How do we know how hot stars are?  Why do black holes form? How did meteorites help our solar system form?  In order to answer these questions astronomers need to be able to use math! Math is an exact science that allows us to understand the universe and our part of it. Join me in our exploration of the universe and discover why and how so many wonderful things happen!

Learners will participate in the following activities:
~ Watch a slideshow about the day's topic
~ Listen as I explain how math helps us understand the topic
~ Watch short video clips to help understand the math concept and how it helps us understand space (occasionally)
~ Discuss the space topic of the session and ask questions to help understand the topic
~ Draw a picture or diagram to show understanding of the lesson
~ In some classes we will conduct calculations based on formulas from astronomy
~ In some classes we will create artistic representations of the concept in addition to diagrams
