  2. Cross section (geometry) - Wikipedia

    en.wikipedia.org/wiki/Cross_section_(geometry)

    A plane containing a cross-section of the solid may be referred to as a cutting plane. The shape of the cross-section of a solid may depend upon the orientation of the cutting plane to the solid. For instance, while all the cross-sections of a ball are disks, [2] the cross-sections of a cube depend on how the cutting plane is related to the ...

  3. Cross-sectional data - Wikipedia

    en.wikipedia.org/wiki/Cross-sectional_data

    Variants include pooled cross-sectional data, which deals with the observations on the same subjects in different times. In a rolling cross-section, both the presence of an individual in the sample and the time at which the individual is included in the sample are determined randomly. For example, a political poll may decide to interview 1000 ...

  4. Section modulus - Wikipedia

    en.wikipedia.org/wiki/Section_modulus

    The plastic section modulus is used to calculate a cross-section's capacity to resist bending after yielding has occurred across the entire section. It is used for determining the plastic, or full moment, strength and is larger than the elastic section modulus, reflecting the section's strength beyond the elastic range.

  5. Cross section (physics) - Wikipedia

    en.wikipedia.org/wiki/Cross_section_(physics)

    In physics, the cross section is a measure of the probability that a specific process will take place in a collision of two particles. For example, the Rutherford cross-section is a measure of probability that an alpha particle will be deflected by a given angle during an interaction with an atomic nucleus.

    Stephen Biesty (/ b i ˈ ɛ s t i /; 27 January 1961 – February 2024) was a British illustrator.Biesty is considered a master of cross section.He frequently collaborated with Richard Platt, who wrote the text for the majority of his books, which covered a wide range of informative cross sections aimed at adults and children, all published by Dorling Kindersley.

  7. Cross section (geology) - Wikipedia

    en.wikipedia.org/wiki/Cross_section_(geology)

    A cross section or cross-section, in geology, is a diagram representing the geologic features intersecting a vertical plane, and is used to illustrate an area's structure and stratigraphy that would otherwise be hidden underground. The features described in a cross section can include rock units, faults, topography, and more.

  8. Mathematics - Wikipedia

    en.wikipedia.org/wiki/Mathematics

    Mathematics has a remarkable ability to cross cultural boundaries and time periods. As a human activity, the practice of mathematics has a social side, which includes education, careers, recognition, popularization, and so on. In education, mathematics is a core part of the curriculum and forms an important element of the STEM academic disciplines.

  9. Nuclear cross section - Wikipedia

    en.wikipedia.org/wiki/Nuclear_cross_section

    The cross section obtained in this way is called the total cross section and is usually denoted by a σ or σ T. Typical nuclear radii are of the order 10 −15 m. Assuming spherical shape, we therefore expect the cross sections for nuclear reactions to be of the order of ⁠ ⁠ or 10 −28 m 2 (i.e., 1 barn).
