  2. United States National Chemistry Olympiad - Wikipedia

    en.wikipedia.org/wiki/United_States_National...

    The United States National Chemistry Olympiad (or USNCO) is a contest held by the American Chemical Society (ACS) used to select the four-student team that represents the United States at the International Chemistry Olympiad (IChO). Each local ACS section selects 10 students (or more for larger ACS sections) to take the USNCO National Exam.

  3. List of mathematical constants - Wikipedia

    en.wikipedia.org/wiki/List_of_mathematical_constants

    A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]

  4. Physical constant - Wikipedia

    en.wikipedia.org/wiki/Physical_constant

    [4]: 128 As a result of the new definitions, an SI unit like the kilogram can be written in terms of fundamental constants and one experimentally measured constant, Δ ν Cs : [ 4 ] : 131 1 kg = ⁠ ( 299 792 458 ) 2 / ( 6.626 070 15 × 10 −34 )( 9 192 631 770 ) ⁠ ⁠ h Δ ν Cs / c 2 ⁠ .

  5. Homework - Wikipedia

    en.wikipedia.org/wiki/Homework

    The intention of homework is to further test students' knowledge at home. However, there is a line between productive work and busy work. Busy work has no inherent value; it just occupies time. Karin Chenoweth provides an example of a student taking chemistry who must color a mole for homework. [13]

  6. Mathematics - Wikipedia

    en.wikipedia.org/wiki/Mathematics

    Mathematics is essential in the natural sciences, engineering, medicine, finance, computer science, and the social sciences. Although mathematics is extensively used for modeling phenomena, the fundamental truths of mathematics are independent of any scientific experimentation.

  7. Differential calculus - Wikipedia

    en.wikipedia.org/wiki/Differential_calculus

    In mathematics, differential calculus is a subfield of calculus that studies the rates at which quantities change. [1] It is one of the two traditional divisions of calculus, the other being integral calculus—the study of the area beneath a curve.

  8. Numerical analysis - Wikipedia

    en.wikipedia.org/wiki/Numerical_analysis

    The field of numerical analysis predates the invention of modern computers by many centuries. Linear interpolation was already in use more than 2000 years ago. Many great mathematicians of the past were preoccupied by numerical analysis, [5] as is obvious from the names of important algorithms like Newton's method, Lagrange interpolation polynomial, Gaussian elimination, or Euler's method.

  9. Mathematics education in the United States - Wikipedia

    en.wikipedia.org/wiki/Mathematics_education_in...

    Mathematics education has been a topic of debate among academics, parents, as well as educators. [4] [9] [195] [38] Majorities agree that mathematics is crucial, but there has been many divergent opinions on what kind of mathematics should be taught and whether relevance to the "real world" or rigor should be emphasized.
