Audio frequency refers to the range of sound frequencies that the human ear can typically hear, which is generally from about 20 hertz (Hz) to 20,000 hertz (20 kilohertz, or kHz). These frequencies encompass the sounds typically encountered in music and natural sounds. Here’s a breakdown of the audio frequency spectrum: - **Infrasound**: Frequencies below 20 Hz, which are generally inaudible to humans but can be felt as vibrations.

Drugfire is a firearms identification technology developed by the Federal Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) in the United States in the 1990s. It was designed to assist law enforcement agencies in linking firearms to crimes through the analysis of bullet and cartridge casing markings. Drugfire works by capturing images of the unique markings left on fired bullets and casings, which are then compared to a database of ballistic evidence from other cases.

The center of percussion (COP) is a concept in physics and engineering, particularly relevant to mechanics and dynamics. It refers to a point on a swinging or rotating object where a perpendicular impact will result in no reaction force felt at the pivot point or hinge. This means when the object is struck at this point, the force of the impact does not transmit through the pivot, allowing for a smoother motion without jolting or shaking at the pivot.

Crystallinity is a term used to describe the degree to which a material has a structured, ordered arrangement of its constituent atoms or molecules. In simpler terms, it refers to how "crystal-like" a substance is. Crystalline materials have a repeating pattern in their atomic or molecular structure, which extends in three dimensions. This regular arrangement contributes to distinctive properties such as melting points, hardness, and optical characteristics.

The term "Green's function" in mathematics and physics typically refers to a type of function used to solve inhomogeneous differential equations subject to specific boundary conditions. The specifics of what you are asking about regarding "Green's function number" are unclear, as it is not a standard term in the context of Green's functions. In general, Green's functions are used in various fields such as quantum mechanics, electrostatics, and engineering to relate the solution of a differential equation to a point source.

Electrical measurements refer to the process of quantifying electrical properties and parameters, such as voltage, current, resistance, power, and energy, within electrical circuits and systems. These measurements are crucial for understanding the behavior of electrical devices, troubleshooting issues, ensuring safety, and improving efficiency. Key concepts in electrical measurements include: 1. **Voltage (V)**: The potential difference between two points in a circuit, measured in volts (V).

In particle physics, "flavor" refers to the different types or varieties of fundamental particles, particularly quarks and leptons. Each flavor corresponds to a distinct type of particle that has different properties, such as mass and charge. For example, the six flavors of quarks are: 1. Up (u) 2. Down (d) 3. Charm (c) 4. Strange (s) 5. Top (t) 6.

Fuel efficiency refers to the measure of how effectively a vehicle converts fuel into energy for motion. It is typically expressed as miles per gallon (MPG) or liters per 100 kilometers (L/100 km) and indicates how far a vehicle can travel on a specific amount of fuel. Higher fuel efficiency means that a vehicle can travel further on less fuel, resulting in reduced fuel costs and lower emissions of greenhouse gases and pollutants.

Insider trading can discourage investment, and cause CEOs to hide information from employees. While there have been arguments that insider trading makes share prices more quickly go to their proper value, the true solution is that if investors dislike insider trading, companies can legally declare that they will only work with those that legally agree not to trade its shares or facilitate insider trading. If someone unaffiliated with the company simply overhears or comes across insider information, this won't stop them, but even if it were illegal, it would be nearly impossible to prove such a case.

At first glance, it would seem pretty ironic for an FAQ that lambasts intellectual property rights to place restrictions on its own distribution, even if just attribution. But asking for attribution is consistent with libertarianism.

It is to prevent people passing this FAQ off as their own work, as they could get social/monetary benefits from doing so, and that should be considered fraud. Even if they don't explicitly claim to be the author when using its contents, that is likely to be assumed by most readers, so not explicitly disclaiming it should be treated as fraud.

This does not mean that anyone who doesn't provide attribution must be sued into oblivion; the punishment must be proportional to the crime, after all, and in most cases, any personal clout gained from omitting attribution will be negligible. But for the very few cases where it's not, the license facilitates the prosecution of such fraud in the current legal system.

Price fixing would require every single company selling something to cooperate. And if they do, another person sick of them can start a new company and undercut them. Price fixing would also destroy any goodwill towards these companies and many customers wouldn't patronize them even if they lowered their prices again.
