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.

Study Aid Review: The Laplace Transform Tutor

 


Laplace Transforms are mainly used as a technique for solving some types of differential equations. If you are a math major and have to take differential equations as a semester-long class you will definitely see it there, and if you are an engineering major that has to take the intro to differential equations class (either as a separate class from intro to linear algebra or in a class that combines the two) you will usually have a couple of lectures on Laplace transforms. If you get good instruction on how to do problems involving Laplace Transforms they are not all that hard. If however, your instructor just glosses over them, they can be very tricky.

In this set, Jason introduces the concept of Laplace Transforms, how to derive the basic transforms, then provides a table of transforms (which is generally what you will be allowed to use in class if you need the more advanced transforms). Then he solves a bunch of problems using the Laplace Transforms, including solving several differential equations. As he does in his other math and science sets, Jason goes through everything step-by-step. He does assume that you have the math skills needed to be at this point (so having taken algebra, pre-calc, and calculus I and II). He does not do a recap of the math, but since he rarely skips steps in solving problems (and never does in the first couple of examples he shows on a topic) you do get a bit of a refresher anyway.

Laplace Transforms is a topic that will come up at least a few times depending on what branch of science or engineering you go into. I was an electrical engineering major and I definitely had to use it extensively in one of my higher-level classes and a bit lighter in a couple of other classes. Unfortunately, I did not have a good grasp on the topic after my Calc 4 class (which is where I was introduced to the topic), so I got this to really figure it out. So, if you are a visual learner who learns best by watching sample problems being worked out, this is a great study aid.
