Earth’s Magnetic Field
In one of his EU lectures Dr. Gerald Pollak makes the suggestion that the atmospheric jet stream of our planet may be an important contributor to its magnetic filed.
The jet stream is
Coulomb’s Probability
The word “and” is normally associated with addition. If Jack has three apples and Jill has four apples, Jack and Jill have seven apples all together. If Jack pulls a pale up a hill
Entropy in the Universe
A common criticism of the eternal universe is that such a universe will suffer heat death trough entropy. All useful energy will at some point be spent, leaving the universe with
Energy on Mercury
Mercury makes its rounds around the Sun a little faster than Newton predicted. This anomaly has been known since Newton's time. But it wasn't before Einstein came along with his curved space-time that conventional science settled the matter for themselves…
Energy Puzzles
Every time we move things from one place to another, we do work by changing the energy of whatever we're pushing around. When we speed things up, we add energy to them. When we slow things down, we subtract. Both…
Mass-Energy Equivalence
The equation E = mc², made famous by Einstein, equates energy to mass. It tells us that an increase in energy equates to an increase in inertia. It also tells us that this happens at the speed of light, in…
Light, Gravity and Energy
Gravity is known to affect the energy of photons. But it isn't immediately clear how this happens. Especially if we don't have a clear idea of what energy is. Let us therefore start with some basics regarding the nature of…
Force, Inertia and Energy
Newton introduced several concepts into physics in order to label the various parts of his equations. He did so without giving any specifics as to their fundamental nature. Labels such as force, inertia and energy were all defined in terms…
Stability of the Solar System
The stability of our solar system is one of the oldest problems in theoretical physics, dating back to Isaac Newton. Newton used his laws of force and motion to determine the motion of a single planet around the Sun. However,…
Magnetic Fields of Planets
Current understanding of planetary magnetic fields is that they are the products of what is loosely termed dynamo currents.
Below ground currents
In the case of our own planet
