Taking a break from the ... everything of everything ... to try my hand at an updated edition of *Calculus Made Easy*. Fortunately, there was a LaTeX transcription at @gutenberg_org, which I grabbed a while ago. (Their website has changed, so I'm no longer sure how to get the auxiliary files.) I've made one pass through for outdated terminology and notation:

Next will be updating the examples that use pounds-shillings-pence currency.

Working some more on my *Calculus Made Easy* updated edition. I think I'll just cut the "bang went saxpence" joke as too much of a 1914-ism.

The one thing in Thompson's presentation that I didn't particularly like is how he introduces derivatives of trig functions. It presumes that the reader has a lot of trig identities in their back pocket, and it makes a simplification that is hard to justify without going into limits, a topic that Thompson doesn't teach. I've tried my hand at a replacement that appeals to the way he *does* teach.

... The *Calculus Made Easy* example about a coal-powered steamship is probably another I should just replace with something entirely new.

... Here is my de-archaized version of *Calculus Made Easy*, with the shillings and the obsolete names for things we now know to be polonium isotopes all fixed up:

And here is how the LaTeX stands at the moment:

Here is my summary blog post about my *Calculus Made Easy* project and where it stands now:

Calculus Made Easy | Science After Sunclipse

... So, I ordered myself a print-on-demand copy of my *Calculus Made Easy* revised edition. Price was a bit steep, since there's no economy of scale when the scale is ... one. I am curious to see how well it turns out. I might order more later to give away as gifts, etc.
I made a book happen

The source linked in my blog post now includes the cover images for printing my *Calculus Made Easy* update (in the .tgz file).

Calculus Made Easy | Science After Sunclipse

Books!
... There is something rather soothing about trying to adopt Silvanus P. Thompson's voice.

As the picture upthread illustrates, I ordered ten paperback copies of my *Calculus Made Easy* updated edition from a print-on-demand service. I've now given them all away, one as a holiday gift and the other nine as bonus freebies at a friend's art show.

I should get serious about this and do another print run. Sadly, the local bookshop that used to offer POD stopped doing that. For this trial run, I used Lulu, for the sophisticated reason that I had an account there because of projects we did years and years ago. Cost per paperback: $8.40.

... With that in mind, what do folks hereabouts recommend for going from PDF to printed books?
... I kind of like the idea, as an art project, of somehow making copies of my revised *Calculus Made Easy* that look like they've been hiding in a library since 1914. This would obviously be just for entertainment value, not the primary form of the book I would like to make available. But I have happy memories of library basements.

@bstacey don't forget minor marginalia making specific jokey references to 1920s British politics
I have ordered more print-on-demand copies of *Calculus Made Easy* and will be giving them away (details of scheme yet to be decided).

I have deemed the Lulu.com printing of my *Calculus Made Easy* revised edition to be good enough. So, I am making it available to order here at cost:

It is available electronically (PDF and LaTeX) via my blog:

@bstacey this is awesome. Thank you!
@bstacey can I buy one
@alilly I've given the printed copies away, but the digital version is available on my blog: https://www.sunclipse.org/?p=3194

@bstacey Do you recommend a printer?

@alilly I've mostly lost track of what services there are; see here for what little I know:

@bstacey I was just recommending Calculus Made Easy to a uni student a few days ago!

@bstacey Some of the wording should never be thrown away...

BEING A VERY-SIMPLEST INTRODUCTION TO THOSE BEAUTIFUL METHODS OF RECKONING WHICH ARE GENERALLY CALLED BY THE
TERRIFYING NAMES OF THE
DIFFERENTIAL CALCULUS AND THE INTEGRAL CALCULUS.

Perfect.

@bstacey reading through this is making me want to build a curriculum around this and similar books (*The Little Schemer* and its sequels come to mind as CS materials without unnecessary complication) for folks who are ready to learn what college only taught them by rote
@bstacey When I set it for screen display and ran the LaTeX through pdfTeX 3.141592653-2.6-1.40.25 from TeX Live 2023 on Alpine it complained a lot and spat a bunch of copies of the word "footnote" on the first page but otherwise seemed to work fine? I'm confused.
@alilly Huh. When compiling with 3.14159265-2.6-1.40.20 either for printing or for screen reading, I get a couple warning messages that say "Command \footnotesize invalid in math mode" but nothing unusual in the PDF itself.
@alilly As noted upthread, I started with the LaTeX version from Project Gutenberg, rather than transcribing it myself, so there could well be peculiarities in the source that I'm unaware of.
@bstacey Maybe I'm missing dependencies or something. I have a log file but can't upload it here.
