  2. Microscopic scale - Wikipedia

    en.wikipedia.org/wiki/Microscopic_scale

    In physics, the microscopic scale is sometimes regarded as the scale between the macroscopic scale and the quantum scale. [2] [3] Microscopic units and measurements are used to classify and describe very small objects. One common microscopic length scale unit is the micrometre (also called a micron) (symbol: μm), which is one millionth of a metre.

  3. Thermodynamic limit - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_limit

    The thermodynamic limit is essentially a consequence of the central limit theorem of probability theory. The internal energy of a gas of N molecules is the sum of order N contributions, each of which is approximately independent, and so the central limit theorem predicts that the ratio of the size of the fluctuations to the mean is of order 1/N 1/2.

  5. Dysplasia - Wikipedia

    en.wikipedia.org/wiki/Dysplasia

    Dysplasia is any of various types of abnormal growth or development of cells (microscopic scale) or organs (macroscopic scale), and the abnormal histology or anatomical structure(s) resulting from such growth. [1] Dysplasias on a mainly microscopic scale include epithelial dysplasia and fibrous dysplasia of bone.

  6. Microscale and macroscale models - Wikipedia

    en.wikipedia.org/wiki/Microscale_and_macroscale...

    The algorithm of Figure 2 is a basic example of what is called an equation-free model. [ 20 ] When mutations are enabled in the microscale model ( σ > 0 {\displaystyle \sigma >0} ), the population grows more rapidly than in the macroscale model (Figures 3C and 3D).

  7. Gas - Wikipedia

    en.wikipedia.org/wiki/Gas

    Drifting smoke particles indicate the movement of the surrounding gas.. Gas is one of the four fundamental states of matter.The others are solid, liquid, and plasma. [1] A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).

  8. Microphotonics - Wikipedia

    en.wikipedia.org/wiki/Microphotonics

    Microphotonics is a branch of technology that deals with directing light on a microscopic scale and is used in optical networking.Particularly, it refers to the branch of technology that deals with wafer-level integrated devices and systems that emit, transmit, detect, and process light along with other forms of radiant energy with photon as the quantum unit.

  9. Ocular micrometer - Wikipedia

    en.wikipedia.org/wiki/Ocular_micrometer

    Ocular micrometer Micrometer Eyepiece. An ocular micrometer or eyepiece micrometer is a glass disk, engraved with a ruled scale, that fits in an eyepiece of a microscope, [1] [2] which is used to measure the size of microscopic objects through magnification under a microscope.
