Chernobyl Would Chernobyl reactor #4 still have exploded if....
These are called "Half Rods" in the usual Nomenclature. Violating operating parameters is never a good thing.- Dozent100

What Is the Typical Energy Efficiency of a Neutron Source?
A Neutron Source emits Neutrons which are not easy to Shield. Typically large thicknesses Water, Borated Concrete, or paraffin are used since they have to be thermalized before they can be absorbed. Neutron Sources are typically Cobalt 60, Californium 256, or the like. They are high intensity...- Dozent100

High School Can Black Holes Really Die and What Are Their Secrets?
I think the question displays a basic lack of understanding of Black Holes and Quantum theory. Rather than a point by point refutation, I will offer the following. The interior of a Black Hole is a mass so thoroughly compacted that the internal space between the atoms are compressed extremely... -

Graduate How Does the Double Slit Experiment Demonstrate Particle-Wave Duality?
That is why they are sometimes called wavicles! Having characteristics of both waves and particles. If there is only one slit available, there will be no interference pattern, because there is not another wave present to interfere with. It is not that there are no wave characteristics generated...- Dozent100

Undergrad Why must we travel through something at C?
Because we want to get there in time. The problem with accelerating to c is that mass increases as V increases. (the relativistic effect) To move at the speed of light, mass becomes infinite. That is why photons and electrons with a rest mass of approximately zero are about the only things that...- Dozent100

Limiting alternator output with resistors in parallel
This is not an unusual problem. Amateurs have used Bicycle driven alternators have been used to power transmitters at Field Days for years. In order to get a usable level of power for a sustainable amount of effort requires and drastic gear down ratio. Something like using the lowest possible...- Dozent100

Troubleshooting Transistor Circuits: Common Issues and Reliable Testing Methods
While the above is true, simple transistors removed from a circuit, should test go/nogo, if you know the type and insert them correctly. The possibility that supporting components are bad while the transistors themselves are OK, would be indication of a well designed circuit. I would check each...- Dozent100

Undergrad How does an induced emf occur in a wire without contact with the magnetic field?
you mean besides Sex? LOL! I have taught many things over the years, but never physics in a classroom setting. I was a practicing Nuclear Engineer and Physicist for over 18 years before I became a Stock Broker and Registered Investment Adviser. I have taught Communications for many years and am...- Dozent100

Undergrad How does an induced emf occur in a wire without contact with the magnetic field?
Then maybe i am confused as to the purpose of this site. Granted my studies were over 35 years ago, but I thought that were we here to help students to understand basic classical concepts. Not to debate subjects that require transcendental formations, Lei algebra, or calculations of Quantum...- Dozent100

High School Understanding Ground Potential: My Experience with a Volt Meter
No! you discharge the potential, that was likely between your hand and Ground. I assume you are referring to the Static Shock those of us who have lived up north. As we walk across carpet, we build up a static charge with a high voltage, Due to the stripping of electrons from the soles of your...- Dozent100
