A Few Thoughts About Human Character

What makes character, and how do we find if we have it? This is something many of us think about and ponder, while measuring ourselves and hoping that we are doing right by ourselves and building the kind of character we want to have. These thoughts are put here in an honest and lovely way...

Earthquake Movements Simply Explained

Recently Christchurch and then Japan had terrible earthquakes with lots of after-shocks. They were caused by Tectonic plates moving under unbelievable pressure.

Some were thought to be Oscillatory, while others were believed to be Trepidatory.  It occurred to me that most people  might be confused about this,  so I thought it wise to let  everyone know the difference.

What's the difference between an Oscillatory and a Trepidatory earthquake ?  

1. Now,  this calculation is just for engineers. If you are competent in this field, this should explain it.

 2.  However, this one is for the layman and, having  access to your e-mailed offerings in the past, you should get the picture straight away. 

 
This is a trepidatory earthquake -- an up-and-down movement.....

This is an oscillatory earthquake -- a side-to-side movement... 

And this is a combination of both trepidatory and oscillatory !!

Now honestly, isn't science beautiful when properly explained?
