Well, I am still looking for my second quarter.
The book of course did not anticipate the pandemic, and finding the second quarter has been difficult. Some commenters have pointed out that cashless transactions are more common now than when the book was published, and of course that is true. But there are other reasons I am having trouble. The COVID-19 pandemic is out of control in Ohio, and the governor has responded by suggesting that everyone stop going out as much as possible. This seems like good advice, and going to the store these days is limited to brief stops to pick up something that was ordered in advance. So there is not much for lingering outside the store, looking for coins. I actually do a lot of walking, up to three miles a day if the weather is decent and time permits, and it is my main form of (physical) exercise.
So, what to do about the exercises? We aren't scheduled to get to Chapter 2 until April, so there is still time. Four of the 11 exercises are tied to the damn quarters, so I will keep trying to find the second quarter through the rest of December. After that, I will consider advancing through the other exercises, particularly as RAW allows us, in exercise No. 5, to come up with "similar experiments" on our own.
How are you doing on your exercises, and do you think I am giving enough time to finding my two quarters? I did find a first one, and I will give it the college try for another couple of weeks to find the second one.
