  2. Inclinometer - Wikipedia

    en.wikipedia.org/wiki/Inclinometer

    An inclinometer sensor's true or absolute accuracy (which is the combined total error), however, is a combination of initial sets of sensor zero offset and sensitivity, sensor linearity, hysteresis, repeatability, and the temperature drifts of zero and sensitivity—electronic inclinometers accuracy can typically range from ±0.01–2 ...

  3. Zone axis - Wikipedia

    en.wikipedia.org/wiki/Zone_axis

    The translational invariance of a crystal lattice is described by a set of unit cell, direct lattice basis vectors (contravariant [1] or polar) called a, b, and c, or equivalently by the lattice parameters, i.e. the magnitudes of the vectors, called a, b and c, and the angles between them, called α (between b and c), β (between c and a), and γ (between a and b).

  4. List of measuring instruments - Wikipedia

    en.wikipedia.org/wiki/List_of_measuring_instruments

    A physical quantity introduced in chemistry; usually determined indirectly. If mass and substance type of the sample are known, then atomic - or molecular masses (taken from a periodic table , masses measured by mass spectrometry ) give direct access to the value of the amount of substance.

  5. Symmetry element - Wikipedia

    en.wikipedia.org/wiki/Symmetry_element

    In chemistry and crystallography, a symmetry element is a point, line, or plane about which symmetry operations can take place. In particular, a symmetry element can be a mirror plane, an axis of rotation (either proper and improper), or a center of inversion.

  6. EC50 - Wikipedia

    en.wikipedia.org/wiki/EC50

    A quantal dose response curve shows the percentage of subjects where a response is noted in an all-or-none manner (y axis) over the dose of the drug (x axis). For competition binding assays and functional antagonist assays IC 50 is the most common summary measure of the dose-response curve.

  7. Rotation - Wikipedia

    en.wikipedia.org/wiki/Rotation

    A sphere rotating (spinning) about an axis. Rotation or rotational motion is the circular movement of an object around a central line, known as an axis of rotation.A plane figure can rotate in either a clockwise or counterclockwise sense around a perpendicular axis intersecting anywhere inside or outside the figure at a center of rotation.

  8. Sinistral and dextral - Wikipedia

    en.wikipedia.org/wiki/Sinistral_and_dextral

    Sinistral and dextral, in some scientific fields, are the two types of chirality ("handedness") or relative direction.The terms are derived from the Latin words for "left" (sinister) and "right" (dexter).

  9. Chemical biology - Wikipedia

    en.wikipedia.org/wiki/Chemical_biology

    An overview of the different components included in the field of chemical biology. Chemical biology is a scientific discipline between the fields of chemistry and biology.The discipline involves the application of chemical techniques, analysis, and often small molecules produced through synthetic chemistry, to the study and manipulation of biological systems.
