On Newton's Third law of Motion

Today, I'm going to blab a lot about physics.  Should you desire to tune out, as so many college students do to their professors, I won't mind.

Isaac Newton, as I said in a previous post, was a scientist back in the 1600s.  He had a lot to do with math, space, and figuring out some of the basic laws of science.  He's famous for his theory of gravity, his discovery of the laws of Calculus, and some of the basic laws of motion.  See that Youtube clip up there?  That's some science guy talking about Newton's third law of motion, which basically says that every force has an equal and opposite reaction.

Basically, that means that for every action, something else exerts a force exactly equal, but in an opposite reaction.  That's why rockets fly: all of the thousands of pounds of fuel exploding down exerts a force, Force A, for simplicity.  Force A also causes a force equal to Force A facing the opposite direction, Force B.  Force B lifts the rocket.

This is one of the basic laws of motion.  It is universally observed, because that's just the way it is.  If you're sitting on a chair with wheels and throw a weight across the room, you'll scoot back a few inches as a result of this law.

This always happens.

Luckily, we human beings are a bit different.  While the third law of motion acts upon us without our even doing anything, there are also different laws that I've thought up.  I've decided to call them the laws of Emotion.

The laws of Emotion are a bit weird, in that they aren't so much laws as suggestions, my observations on how to be happy.  The first one is, "Happiness is determined by you."

We are in complete control of our emotions.  We often hear people say, "He made me sad."  Truth is, you decided that you were sad because of something he did.  We often react, instead of simply acting.

The most difficult thing to do is just be happy, regardless of your situation.  If we are focusing on the things that truly matter, we can be happy no matter what happens.  It may be difficult, but it is possible.  We can be in pain, have nothing, or be mourning, and still be happy.  It's all a matter of attitude and desires, and whether we are focused on Jesus Christ or not.  Jesus will help us be happy no matter what.
