Week 7

Newtons three laws and me...  Well, I could put those into motorcycle terms again...  When I am in motion n the motorcycle, it will want to stay in motion, but the frictional force of the tires on the ground, as well as the mass of the motorcycle and myself pushing through the atmosphere will want to slow me down until I reach a complete stop.  I experience that almost every single day and have for a long, long time. Second law, the acceleration of mass, myself and the motorcycle propelled forward in acceleration by the power produced by the engine.  Simply the acceleration of mass.  third law:  When I begin to accelerate from a complete stop, it is the rear tire of my motorcycle pushing against the ground to push me forward, but how do I know that maybe just a small part of me going forward, is my motorcycle pushing the Earth backwards.  Is that a measurable force upon the Earth's rotation as well as orbit?

Our "energy efficient" culture:  Are we an energy efficient culture?

    So, I’m sure you’ve ridden Hwy 1 along the coast into Stinson. And there are a lot of spots where you just have to lean and get heavier on the throttle. All physics aside, I wonder why that feeling of accelerating through the apex of a turn is so blissful. What is it about the increase in g-forces that makes us love a road like that? I guess I’m trying to figure out how that feeling of joy serves us from a biological perspective.

Physics week 4

E=mc2 has effected my life and my career of the past decade or so.  Working with motorcycles, the engines as well as the braking systems to the electrical and right down to the tires, e=mc2 is everywhere.  The internal combustion chamber engine is the easiest form of energy to be seen and felt.  The electro-magnet stator and charging system that creates the electrical energy to send the tens of thousands of volts to the spark plug to help the fuel combust.  The energy a[applied to braking system that slows the bike down, and the give, squish and flex of the soft tire compound gripping the concrete as the bike goes through acceleration or deceleration.  All of it exhilarating, fun to work with and even better to be able to find and fix a problem with a particular machine. The four forces: It is to my understand that gravity, the base power of 10, is to be the baseline for measuring the energy of the strong, weak , and electroforce.  So, how would I compare them?  I guess I  could tr

Week 5

Ordered Chaos does sound familiar, without it, the world would not be where it is today.  Ordered chaos is the push for evolution and adaptation.  Nature would not have evolved nor would it have matured without ordered chaos.  If everything stayed the same and predictable, everything would still be just that, the same and predictable.  But because the chaos comes around from time to time, animals, insects, people and every living thing must act accordingly to survive, otherwise the chaos will eventually destroy them. Fractals as complex systems...  Just merely breaking down that statement in a literal sense it only seems true.  Fractals, a fraction of larger piece or a fraction of a larger complete system.  So if a complete system can be complex, the fractal part of it can only hold the same complexity.  If not only more complex because of the lack of ability to see the whole system.  that, or I just missed the big picture. Consciousness out of chaos...  I think of this similar to
