Welcome

Welcome to my ever-evolving blog. It started out as a blog on Beachbody workouts and products, mainly when I was a Beachbody coach. I no longer coach, not because I don't believe in Beachbody's programs (I subscribe to Beachbody on Demand and use their workouts every day), I am just not a salesperson and hated that aspect of it. I am more than willing to answer questions about my experiences with their products and the various workouts, and I feel freer to do so without the appearance of giving a biased review of something.

I have also started adding reviews for various things I have purchased like movies, books, CDs, and other products. This was brought about by a fight with Amazon in which all of my reviews were removed over a completely bullshit allegation that I posted a review that violated their terms of service. After going back and forth with the morons in the community-reviews department (even after they admitted that my posts did not violate their guidelines) they restored my account (which took them six months to do), but I have been posting my reviews on my blog to have them preserved in case something like that happens again. And here, I will post uncensored reviews so I will swear from time to time and post reviews that may be longer than Amazon's character limit. Everything I post here on any topic or product is my personal opinion, and I take no compensation for any product reviews I post. I am a member of Amazon's vine program and because I get those products for free, I keep those reviews on Amazon only, but everything I have purchased with my own money, whether from Amazon or some other store/website/outlet, I will post here.  

I also plan to do some longer blog posts on various topics, such as how to learn physics, how to get through calculus, and longer reviews of workout programs as I do them. Basically, whatever strikes me as interesting at the time.  As you can see if you navigate around the blog, I had many years in between postings. During that time I was going back to school to get an engineering degree, and learning material that I avoided my first time through college was a different experience and one that gave me a lot of insight into how to do well in those classes, which I will try to impart here for those who are looking to get a science or engineering degree.

Textbook Review: Linear Algebra and Its Applications, 4th Edition

 


This was one of the required books for my Calculus 4 class, which was a combination of an introduction to linear algebra and an introduction to differential equations. So, it was not a full course for either subject and as a result, we did not cover everything in this book. 

This is a pretty standard math book. It explains the theory fairly well and generally does not make it harder than necessary to learn the material. It gives a decent amount of examples, although, like all math textbooks, the examples tend to be of the "easier" problems, while the problem sets can get a lot more complicated. One thing that was a pain about the book is that many times in the answer key at the back, instead of giving an answer to an odd-numbered problem it will refer to the solution manual, so you could not even get the answer to the problem to see if you did the problem correctly.

Overall, I would say it is a decent book. It is not the best math book I had to use as I was getting my degree, but it is certainly not the worst. If you are trying to learn the material yourself, it will be a helpful reference, but you may want to get one of the study aid supplements out there to help you work through the problems.
