The Power of Sound – Sonic Warfare

The power of sound

The power of sound

Sound is an amazing force, and one that is often overlooked in terms of its powerful influence and destructive potential. The lucky ones among us get to hear sound every day, and what a privilege it is. There are times, however, when hearing may be a detriment to us. This is increasingly becoming the case with the development and application of sonic weapons by various military forces. Sound as a weapon is not a particularly new idea, but for years there has been much secrecy and misinformation shrouding the subject. Read more »

Thoughts on the Length of a Day on Earth

I’d like to share with you my thoughts on day length and where it is headed. First, let’s just refer to Wikipedia’s definition of day length:

Day length… refers to the time each day from the moment the upper limb of the sun’s disk appears above the horizon during sunrise to the moment when the upper limb disappears below the horizon during sunset. Due to the diffusion and refraction of sunlight by the atmosphere, there is actually daylight even when the sun is slightly below the horizon. The period when it is still somewhat light even though the sun is below the horizon is called twilight.” – Wikipedia

Chaos Theory – Part One

Strange Attractor

Strange Attractor

What is chaos? We hear the term often enough, what does it mean? There are many aspects of our universe that seem to have no order, make no sense and have no underlying structure. They just ‘are’, and will continue to ‘be’. This is satisfactory for some, but others struggle to accept that some things are just too chaotic for us to ever understand. These same people may also believe that there must be some underlying structure to these systems, that there cannot just be total chaos. Chaos theory is the process of trying to discover the structures and processes that are present within these systems and to understand and predict future outcomes. At this stage it may be useful to mention a few systems that are chaotic in their structure. There are changes in the weather, the movement of satellites in the solar system, ecology and population growth, molecular vibrations. There is also speculation over the existence of chaotic dynamics in plate tectonics and in economics. Ecology still remains one of the best examples of a chaotic system. Population growth and distribution, like all chaotic systems, are very dynamic and deterministic, meaning that future outcomes depend heavily on initial conditions. This is the basis of chaos theory: the hope that we can understand the structure and differences caused in various outcomes through differences in the systems initial input. Read more »
