Physics The Easy Way

Physics seems formidable to many, but this book does truly make it much easier to understand. "Easy" is relative, but this is the best book I've found for high school homeschoolers. It has plenty of real math problems so it's not a dumbed down "story" of physics. Rather, it takes you slowly from easy concepts to more advanced... [More]

PHP Example for Amazon Signed Request

Simple Example of PHP changes to comply with Amazon's requirement to Authenticate and Sign all Requests to AWS, now known as the Product Advertising API. This may affect some homeschool websites.

Amazon documents hint at how to do this, but there's no sample code for PHP - Here's how I got it to work

Update on "Proving God Exists" article

I wrote this short article on "Proving God Exists" about 15 months ago. Last week, it received a rush of new traffic via Stumble-Upon, along with new comments from various readers. Three of the comments led to dialog which may interest theists, Christians, and skeptics alike.

Learner.org Free Online Courses/Video

Learner.org offers many online classes programs and lectures suitable for high-school homeschoolers. I've enjoyed The Art of the Western World. This is a PBS style documentary with vivid detail that is a joy to watch. The program is not produced from a biblical viewpoint so parents should watch it with their children and discuss the various interpretations offered by the program.

Another great help to parents is learner.org's The Mechanical Universe. This complete introduction to high-school and college physics will interest student and parent alike. It's not a rigorous classroom lecture, but another PBS style documentary. Just enough math is provided to motivate the student to dig deeper and interact with the concepts and equations found in traditional "textbook" physics. Study Notes and coordinated textbooks are available for purchase on the site. We haven't seen these personally.

Take advantage of these Arts and Science programs, as well as the dozens of others offered at learner.org.

Proving God

While there are various proofs for God's existence, I've found this to be the simplest and therefore the most compelling. If you can refute this, let me know. Seriously, I believe this sums up the claim in Romans 1:19-20 and is undeniable. I'm sure others have expressed this argument, but here it is in my words....

Why Algebra?

The question "is Algebra really needed if my child is not interested in math/science?" comes up now and then among homeschoolers.  Here's what I think:

Algebra is essential.  Not everyone will solve equations for a living.  But you need to be able to think in terms of "functions" - meaning how one thing varies as a result of a change to another thing on which the first thing is dependent.  To have an intuitive sense of this is priceless.  Algebra trains this type of thinking.  "Functional" thinking works in politics, relationships, science, finances, etc - really in all of life. 

Algebra is just learning to convert various functions into different forms so they can be understood and manipulated more easily.  This idea of "transforming" one problem into another type is also essential.  Some problems are truly unsolveable as presented, but clever rethinking may show how it can be solved from another perspective - another essential life skill!

Algebra is wonderful to train proper thinking, as there is always an "objectively" correct answer - not a subjective "I think/you think" impasse common to so many of the "soft" sciences.

Universe Beyond Understanding

If things keep going the way they are...in 100 billion years the only galaxies left visible in the sky will be the half-dozen or so bound together gravitationally...Unable to see any galaxies flying away, those astronomers will not know the universe is expanding and will think instead that they are back in the static island universe of Einstein.
“observers in our ‘island universe’ will be fundamentally incapable of determining the true nature of the universe.”  

"...fundamentally incapable of determining the true nature of the universe."  Hmm, the New York Times admits that humanity's scientific endeavor may have fundamental limitations?  Has a dangerous cat escaped from a formerly impenetrable bag?...
