Orbital Mechanics Coloring Book

Please support my efforts. I just finished the 2nd edition of my conic sections and orbital mechanics coloring book. I need help with printing costs. Through this Kickstarter you can pre-order a signed coloring book. I look at conic sections, Kepler's laws, Hohmann transfer orbits, the Oberth effect, space tethers, Tsiolkovsky's rocket equation and lots of other space stuff. The coloring book is $5 plus $5 shipping and handling ($10 shipping and handling if you're outside the U.S.).

Kickstarter for this coloring book ends 4:30 a.m. April 13, 2020.


“The most sophisticated people I know - inside they are all children. ” 
― Jim Henson

I agree with Henson -- many of the folks I most admire are just big, playful kids. Henson (of the Muppets), Theodor Geisel (aka Dr. Seuss), Carl Barks (Uncle Scrooge, Donald Duck, Huey, Dewey and Louie), Stan Lee (Marvel Comics) are a few of favorite artists/kids.

My coloring book is aimed at kids. It's aimed at adults too. At least I hope there's a lot of adults like myself that like kid stuff.

I try to give info on the conic sections is a visual, accessible manner as well as have some fun. Here's some of the pages:

The above are a few of the book's 40 pages. It's my hope it informs and entertains kids as well as adults. Getting folks interested in outer space is also a goal.

It is available at Conic Sections & Celestial Mechanics Coloring Book by Hop David.

My other coloring books can be found on my Amazon author's page.

Why does it cost almost 400 bucks?

(Going to the Amazon page... ) Oh my gosh. Underneath the $349.00 price tag are options to buy it new for $10. I have not idea where that huge price tag comes from. Regular retail is $10.00.

Hm, but it still seems rather hard to get a hold of, especially for someone not located in the US. And by now the original Amazon listing with the ridiculously huge pricetag has disappeared as well, leaving behind only a "Buy used" option...

Here is a another link:

The top vendor on the page I'm looking at is Arizona Publishing Services, the folks I hired to make this book for me. Their price is $10. Don't know what shipping would be.
