Gravity effect of selected bodies
The simple geometrical bodies are often used for the modelling before the survey is carried out. The aim is to get a rough estimate of the anomaly effect of the…
What is the Heisenberg Uncertainty Principle?
The Heisenberg uncertainty principle, stated in a way that's useful for chemists, is that it's impossible to determine simultaneously with high precision both the momentum and position of an electron. In practice, this…
Rock densities
The densities of rocks (Tab. 1.1), naturally, depends on the mineral composition of particular rock. However, not only mineral composition, but also other factors influences densities. The next main factor,…
Hamiltonian Operator
A molecule is a group of atoms held together by chemical bonds. In quantum mechanical terms, a molecule is a group of particles consisting of at least two or more…
The Equipartition Principle
The equipartition theorem, also known as the law of equipartition, equipartition of energy or simply equipartition, states that every degree of freedom that appears only quadratically in the total energy…
Operating Legally
An Overview BEFORE you start... v Select the legal form for the business (sole proprietorship, corporation, partnership, or limited liability company). v Apply for federal and state employer tax identification numbers if…
Break-Even Analysis
Break-even (B/E) analysis is a simple, but very effective financial feasibility test. B/E is used to determine the amount of sales necessary to pay all fixed costs (and have zero…
Researching Your Market
Many businesses will require some outside research to estimate the demand for products/services. This is especially true if you do not have extensive experience in your new venture. Start by…
Thinking Versus Noticing
Startup founders can often find themselves working on an idea that sounds plausible, but does not provide a solution to a problem people care about in a meaningful way. Y…
Gravity meters
Basically, there are two main gravity types – the absolute and relative gravity meters. In geophysical prospection solely the former are used. They measure relative gravity – the gravity changes,…
