**Spring Problem**

In diagram 1, we don’t know where y is when the body is at rest. In diagram 2, x = .5x 0 , assuming the spring is uniform. That gives the spring energy as, E spring = .25kx 0 2 While in diagram 1, E spring = .5ky 2 Therefore the transformation between diag...

**Superposition and Quantum States**

A lot of confusion in Quantum Mechanics is the result from not being able to differentiate between the real world and the Hilbert Space. Vectors in real space – like velocities, accelerations, forces, etc. – are objects one can actually measure in the real...

**Entanglement and the Uncertainty Principle**

Here's your typical experiment. Suppose these particles are electrons and they are sent one pair at a time. At O, the two electrons are released from rest and sent in opposite directions, and of course because of the conservation of angular momentum, they ...

**What the Right fails to understand**

The Right position has historically been for leaner government, lower taxes and fewer regulations. As we have already explored in What governments often fail to do is that cuts in government spending in an overheating economy is the right prescription, but ...

**What the Left fails to understand**

When the Left was fighting for better working conditions, better wages and gender equality, it had a noble task. This is no longer true. What it fails to understand is a basic economic concept, which can be simpliflied with the following illustration: Wealt...

**Killing Vectors and Hawking Radiation**

Preliminary We start out with the interval (see equations (6) to (23) in Relativistic Doppler Effect ), (1) ds 2 = -dt 2 + dx 2 + dy 2 + dz 2 We define the metric as the coefficient of each of the terms in the above: (2) η 00 = -1, η 11 = 1,η 22 = 1,η 33 =...

**The Equivalence Principle: BBT or SUT**

Einstein made the following reasoning: he took the Doppler Effect and using the Equivalence Principle, turned it into a Gravitational Shift. And then from there, he derived his eponymous Field Equations. See The Essential General Relativity . By reversing ...
