  2. Antiproton - Wikipedia

    en.wikipedia.org/wiki/Antiproton

    The use of antiprotons allows for a higher average energy of collisions between quarks and antiquarks than would be possible in proton–proton collisions. This is because the valence quarks in the proton, and the valence antiquarks in the antiproton, tend to carry the largest fraction of the proton or antiproton's momentum .

    en.wikipedia.org/wiki/Singapore_math

    A bar model used to solve an addition problem. This pictorial approach is typically used as a problem-solving tool in Singapore math. Singapore math teaches students mathematical concepts in a three-step learning process: concrete, pictorial, and abstract. [3] This learning process was based on the work of an American psychologist, Jerome Bruner.

    en.wikipedia.org/wiki/P-chart

    The binomial distribution is the basis for the p-chart and requires the following assumptions: [2]: 267 The probability of nonconformity p is the same for each unit; Each unit is independent of its predecessors or successors; The inspection procedure is the same for each sample and is carried out consistently from sample to sample

  5. Notation in probability and statistics - Wikipedia

    The probability is sometimes written to distinguish it from other functions and measure P to avoid having to define "P is a probability" and () is short for ({: ()}), where is the event space, is a random variable that is a function of (i.e., it depends upon ), and is some outcome of interest within the domain specified by (say, a particular ...

    These problems were characterised in his speech as "unattackable at the present state of mathematics" and are now known as Landau's problems. They are as follows: Goldbach's conjecture: Can every even integer greater than 2 be written as the sum of two primes? Twin prime conjecture: Are there infinitely many primes p such that p + 2 is prime?

  9. Multiple representations (mathematics education) - Wikipedia

    en.wikipedia.org/wiki/Multiple_representations...

    The use of multiple representations supports and requires tasks that involve decision-making and other problem-solving skills. [2] [3] [4] The choice of which representation to use, the task of making representations given other representations, and the understanding of how changes in one representation affect others are examples of such mathematically sophisticated activities.
