Newton's First Law of Motion

Sir Isaac Newton first presented his three laws of motion in the 'Principia Mathematica Philosophiae Naturalis' in 1686. His first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. The ...

Synchronicity

SinchronicityThere's something called synchronicity that we've probably all experienced at one time or another. Some people prefer the term 'meaningful coincidence.' You're thinking about your friend from high school whom you haven't seen in 20 years, and lo and behold she calls you up the next day. Or you hear Larry King use the word propinquity only a few hours after you looked the word up in the dictionary. What do these kinds of meaningful coincidence mean?

One way to look at synchronicity is to see it as a sign that your mind's unusually energized. The idea is simple: the more alert you are and the more actively you're engaged in the world around you, the more things you'll notice and the more likely it is that you'll find patterns, coincidences, and repetitions. If you're depressed, you won't experience much synchronicity in your life. If you're manic, you'll experience lots of it. Carry it too far, as paranoid-schizophrenics do, and you'll experience so much synchronicity that you'll be considered crazy.
