A unit of number density, amagat, was named after him.

In other words, if the ratio between electric field and number density is constant, we expect similar dynamics.

It can also be formulated in terms of the total number density N:

The parameter has units of number density and provides the normalization.

The forces also influence the number density and alignment of trabeculae inside the bone.

Therefore the mean free path is inversely proportional to the gas number density.

Younger still are a few areas smaller than maria which bear yet lower number densities of craters.

Number density is the quantity of some specified particle or object class per unit volume.

An amagat is a practical unit of number density.

Compare this with a number density of roughly 10 molecules per cm for liquid water.

For example, a sufficiently high particle number density may lead to significant Stark broadening.

Consider a system of particles in a volume (for an average number density ) and at a temperature (let us also define ).

The number density of nucleons in a nucleus is therefore:

This corresponds to a predicted number density of 10 cm in dense clouds.

With increasing number density of deposited particles, the blocking function decreases.

Number density is the number of specified objects per volume:

The following table lists common examples of number densities at 1 atm and 20 C, unless otherwise noted.

"I wish I could remember the number density for the interstellar plasma near the sun.

The xenon appears in trace amounts (concentrations by number density ranging from 1% to 8%).

Population density is an example of areal number density.

The universe, as a whole, seems to have a nonzero positive baryon number density - that is, matter exists.

From this total number density only those particles that are within one particle radius will be able to interact with the boundary.

The state vector could be temperatures, ozone number densities, humidities etc.

"Check number densities, temperatures, electric, and magnetic field strengths.

The stress is proportional to the number density of the contacts, N, and their average spring constant, κ.
