New Book Coming! Gravity


I’m moving fast with the new book “Gravity”!

I’m starting with newtonian gravity, some Kepler’s Laws, and some other fun subjects.  There will be some more modern gravitational theory such as space-time curvature and gravitational lensing in there, but only at a basic level.  My new plan is  to put out short booklets of 30-50 pages that cover a specific subject rather than whole texts.  I still want a larger Interactive Physics textbook someday so I am constantly adding the booklets I am creating into a master text containing everything.  That file is becoming pretty large.  I may release the larger incomplete textbook like the E.O. Wilson book and just update it when new sections are written.  We’ll see.

I have also published a book on Basic Circuits.  This is just a few sections from The Electric Force that are on circuits.  This is a $0.99 book for folks that just want the circuits part.  Also, I published Math and Motion, a book that is important because it goes into the measurement, mathematics, algebra, and some kinematics.  I put it out, but it is unfinished.  Really, it was killing me to keep working on it and I’ve had enough.  As with the other books, I will post new sections to the books often and you can download the updates for free.  It’s really a new way of looking at textbooks.  Out of date textbooks should be a thing of the past as new knowledge and sections can be added and the changes downloaded.

Here are the covers along with links to the iBookstore where you can purchase them:
