The Heatwave of Summer 2022

A student recently told me, when they first read my post on climate change, they found the issue very far away from them. But when the recent heatwave (summer 2022) hits, they realized that climate change might be the defining issue of their generation. Here I share a few articles which may hopeful wake-up more young people.

Farewell, Mike!

My uncle Mike (Michael J O’Connor) passed away this week. I have only met Mike once in person when I visited Atlanta a couple years ago. It was a brief visit, but Mike’s hospitality made me feel very welcomed. He took me for lunch at Whole Food and had a walk with me in a beautiful park. The morning when I was having breakfast with him at his home, he showed me deer in his backyard with the excitement of a child. That was one of my fondest memories. ...

A Few Stories of My Grandma

This is a link post from my family memorial website. A Night of Stories My grandma, Xin Zhao (赵欣), passed away on March 8, 2022, when she was 93 years old. To tell the truth, despite her always being kind to me, I knew very little about her life as I was growing up. When I was in college, my grandpa passed away and my grandma relocated to the US. From that point on, we had fewer chances to meet. ...

What podcast am I listening to?

I have been staying at home and teaching online for nearly a month and half now. During this time, I picked up my old hobby of listening to podcasts. Don’t get me wrong. I never stopped listening to news. But recent global events made me feel that it is probably not a good idea to consume too much news. So I switched to listening to some more educational and entertaining podcasts. Here are what I am listening to. ...

Writing an exam paper with Julia and Jupyter Lab

I just taught Linear Algebra, which means I need to give exams with a lot of questions about computations. I would like to have the numbers in this problems to be random, and I like to solve them with computers. (Sorry, students. Only you need to compute by hand. 😆) I have tried to use Mathematica to do so. The math parts works well. But the typesetting of Mathematica looks quite ugly. ...

Why I don't reply emails (Or effective use of edstem.org in teaching)

In the past two months when I taught Linear Algebra, I used the Q&A website Ed (edstem.org) to answer questions from students. My main motivation for using Ed is to avoid answering the same questions repeatedly. If a student post a question on Ed and I reply, everyone else can see my answers. This goal is mostly achieved. However, I also want to train students to write about mathematics formally, and to foster a sense of a community among students. These goals turned out to be a bit more difficult. ...

On Making New Habits

I came across an interesting article A behavioral scientist’s advice for changing your life. Here’s an excerpt If you’re trying to develop a habit like working out regularly or writing each day, letting yourself have a little leeway is the way to make that habit stick. If you know when you might procrastinate, impose a fine on your future self and commit to paying if you don’t follow through with your goals. ...
