PEOPLE OF THE WOLF (O'NEAL-GEAR): to Chapter 45. The People (the POV tribe in the story), led by Wolf Dreamer's aggressive twin brother Crow Caller, launch their first retaliatory attacks against the enemy tribe. The younger men get their first taste of violence and cruelty, and find that they like it. The passing of two beloved figures forces both Wolf Dreamer and Dancing Fox to make difficult choices. The shaman Heron, in her final vision, glimpses a warm land to the south - an alien landscape filled with strange creatures. Meanwhile, Ice Fire, the shaman of the enemy tribe, harbors a disturbing secret - and a mystical connection.

KING OF THE VAGABONDS (STEPHENSON): to Saxony, April 1684. Jack encounters an ostrich in Oesterreich, and makes his getaway from the Siege of Vienna with Eliza, whom he has liberated from a harem. Jack reveals the nature of an unfortunate accident that has left him short-changed in the romantic department. He and Eliza roam the Bohemian countryside through the winter of 1683 - '84, subsisting on a limited diet that leaves Eliza weak. Eliza, smuggling the precious ostrich plumes, hatches a plan to buy mining shares. They travel to Leipzig, where they meet a certain scholar, "the Doctor", who is working on certain mathematical discoveries rivaling those of the Englishman Newton. The Doctor is everything Newton is not - urbane, sophisticated, a ladies' man (which Newton definitely is not), and able to enjoy a trashy romance novel with the best of 'em.

Stewart (Calculus, 9th ed.) states that Leibniz "sought to develop a symbolic logic and system of notation that would simplify logical reasoning. In particular, the version of calculus that he published in 1684 established the notation (dy/dx) and the rules for finding derivatives that we use today." The priority dispute between Newton and Leibniz is one of the main themes of Stephenson's Baroque Cycle.

You get good at anything by practicing it a lot, and that includes mathematics. I wanted to bring my foundational math skills up to a good strong level, and I didn't want to schlep around a lot of textbooks. So after a little poking around I discovered Kuta Software (based in Istanbul), which markets a line of "Infinite" math worksheet programs aimed at the grade school to college levels.

https://www.kutasoftware.com/index.html

I started using the software last night and I'm very happy with the product. Right now I'm working on solving polynomials by completing the square; this is one of those operations that you can learn step-by-step in a few minutes, but it's only by working many practice problems that it becomes natural.

The topics covered range from arithmetic to calculus. You set the parameters for your worksheet (topic, number of problems, easy/hard, involves fractions or doesn't, etc.) and the program spits out as many worksheets as you want, with fresh problems each time. You can refresh the random values each time so you never run out of problems - hence, "Infinite".

Now that I'm officially working in the IT field, I'm going to want to make sure my technical skills are strong, and notwithstanding my age I'm still hoping to get around to finishing that BS degree in Physics or Engineering. An endless supply of practice math problems will help me stay in the game.
