Book Progress

 

I'm working on removing anything unnecessary from Althea and the Mysteries of Calculus. So far I've only removed 15 pages. At that rate, it would take me a year and a half to get it down to 350 pages. I'd better pick up the pace.

I'm also improving things that beta readers have asked me to. The characters need to move around a little more, and have little physical quirks. I'm working on that. D suggested that one of the characters might chew on their pencil when thinking, and then their pencil would bump into their mask. I like that image. I haven't found a spot yet where it will work, but I hope to.

Someone just asked to read the first book. I wondered what made him ask just now, since I haven't recently asked for readers. I realized maybe it's that school has ended.

 

If your school year has recently ended and you or your kids would like to read one of Althea's Math Mysteries, just get in touch at altheasmathmysteries@gmail.com. I'm still in need of beta readers.

 

More information about the books here. 

 

What is calculus?

It finds slopes on curves,

And areas inside curvy shapes.

So it can find a changing velocity,

Like with gravity.

 

How does it work?

We use two points to find slope of a line, rise over run.

But we want the slope of a curve at one point.

So Newton and Leibniz “cheated”,

Putting the two points infinitely close together.

It works.

 

If you want to learn more,

Althea and her friends are exploring calculus

And you can join them.

Progress: Althea and the Mysteries of Calculus, version 8.2

 

Minor changes

The front image is much nicer now. It's still not a professional illustration. That will happen after we begin our kickstarter campaign, and that won't be for many months, at the earliest.

I decided the predictability of having Althea's Math Journal after every chapter would feel good to readers. But the first two Mondays had two chapters each, and she can't be writing her journal in the middle of a gathering. So I had to combine chapters 1 & 2 and also chapters 5 & 6. Done.

Also, at 450 pages, the book is way too long. I intend to shave off at least 100 pages. I found some bits in chapter 1 that could go. (Some of that appears in the Activity Book still.) So that chapter is a reasonable length, I think. So far, I haven't found anything to take out in what is now chapter 4. I hope folks giving me feedback can help me with that. I think it comes in too long at 26 pages.

I'm still finding places where I need to add a bit to make the math clearer. But more and more, I'm also finding bits that can go. Adding a touch of color here, removing something out of place there. I feel like a sculptor or painter. Ahh.

I wish it were easier to find beta readers. (I have a story to tell about that. It will be in a blog post soon.) If you're interested, email me at altheasmathmysteries@gmail.com.
