Considering Others

Why is it that when we are behind the wheel of a car we automatically think that nothing we do affects others? In reality driving down a crowded street is no different than walking down a crowded street. We see many other people as we make our way along with the crowd. When we are walking everything seems to go smoothly. We nod a polite hello to strangers, we give each other space, and we generally interact in a polite manner. This simple interaction almost never leads to blatant offenses between two individuals, because we all know how to behave in these situations.   Put us in a car and we become crazy jerks. We drive around like everyone else is some kind of moron and we are the only ones that have any business being on the road. We become quick to judge, quick to offend, and quick to let our sense of decency and courtesy go out the window. Every offense that we commit against another motorist we quickly brush off as ultimately being someone else’s fault. We try to teach others les

Like Perpetual Energy, Not Really

A device that creates electricity and then uses that electricity to create more electricity sounds like a great thing and indeed it would be. The alternator on your can almost do this but not really. Perpetual energy is scientifically impossible, at least with what we currently understand about the laws of thermodynamics. The alternator is a type of generator so it essentially creates electricity, and to do this it uses electricity, quite often originating in the alternator. The force, or the energy that really makes all of this possible is the rotating force of the engine. The alternator is driven by a belt that is turned using a pulley attached to the crankshaft of the engine. This is the real driving force that makes electrical generation possible within the alternator. The rest is simply a matter of electromagnetic induction. Electromagnetic induction occurs when a magnetic flux or field passes over a conductor. The point at which the magnetic field collapses around the conductor i
