Abrazol Publishing Newsletter, November 2022

It's been awhile since our last newsletter. We are still alive and still producing books. Here's an update on what's going on.

To start, here's our bestseller list for the month of October. The list is in order of sales with the highest first.

  1. Max and Moritz: a Dual Language German-English Children's Story
  2. Combinatorics Problems and Solutions
  3. Struwwelpeter: Dual Language German-English Children's Stories
  4. Information Theory: A Concise Introduction
  5. Finite Automata and Regular Expressions: Problems and Solutions
  6. Combinatorics II Problems and Solutions: Counting Patterns
  7. Engineer's Notebook on Inductor and Transformer Circuits: problems, solutions and simulations
  8. Pairs Trading: A Bayesian Example
  9. Pattern Generation for Computational Art
  10. Probability Problems and Solutions
  11. Art of Pi
  12. Art of the Golden Ratio
  13. Bet Smart: The Kelly System for Gambling and Investing
  14. Nell: An SVG Drawing Language
  15. Passive Butterworth Filter Cookbook
  16. Recursive Digital Filters: A Concise Guide
  17. Signals from the Subatomic World: How to Build a Proton Precession Magnetometer
  18. The Enigma of the Crookes Radiometer

Two of our bestsellers are dual language children's books, something we never could have imagined when we first published them. This falls into the bin labeled "And now for something completely different".

The combinatorics book is a perennial bestseller, but only during the academic months, no surprise there.

Information Theory: A Concise Introduction has really been gaining in popularity recently. We will be coming out with a new edition of this book that has more problems and solutions, no timeline yet.

So far this year we have two new books. The Enigma of the Crookes Radiometer is about the history and physics of that little device with the turning vanes inside a glass bulb. When you put the device in the sun the vanes start to turn, no batteries required. Few people understand how this device really works. Most of the usual explanations are wrong. The physics behind it is really quite interesting and not that easy to explain. We do our best to try to explain it in a way that most people can understand. The history of the device covers all the different variations that Crookes produced. We're working on a video related to the Crookes radiometer.

The second book is Engineer's Notebook on Inductor and Transformer Circuits: problems, solutions and simulations. This book was written for engineers that need to design circuits with inductors and transformers.

A couple good quality videos we've come across recently:

  1. Nima Arkani-Hamed: The End of Space-Time
  2. Particle Fever (Documentary)

We thank everyone who has bought our books and will buy our books.
