Uncertainty

In 1927, German physicist (and future Nobel Prize Winner) Werner Heisenberg developed his now famous "Uncertainty Principle".  It states that certain pairs of physical properties, such as position and momentum cannot be simultaneously known to arbitrarily high precision. In other words, the more precise your measurement of an object's position in space the less precise your measurement of it's speed and vice versa. 

Heisenberg's Uncertainty Principle shook the world of physics. Albert Einstein, the legendary father of relativity, couldn't accept it on face value.  Einstein believed in balance, symmetry, and order.  He would not allow himself to believe that the universe was based on nothing but pure chance and luck.  His now famous response: "God does not play dice".

I'm not so sure about that.

Uncertainty outside of the world of theoretical physics is, I'm quite sure, something we all have stories about.  Just when it seemed you might get that job offer, there's no call back.  You feel you're an important contributer to the company mission and vision, and then you're laid off.  But it's not all negative.

We've been told you make your own luck. I'd like to think so, but what I believe you really should make are plans for various outcomes.  Always have a strong Plan B, and a workable Plan C.
