    In chemistry and biochemistry acid dissociation constant , the acidity constant , or the acid-ionization constant equilibrium constant that indicates the extent of dissociation of hydrogen ions from an acid . While strong acids dissociate more or less completely in solution and consequently have large acidity constants, weak acids do not fully dissociate and generally have acidity constants significantly less than 1. Because this constant differs for each acid and varies over many degrees of magnitude, the acidity constant is often represented by the inverse of its common logarithm pH , though not related directly).

    Categories Fundamental constants
    Planck's constant , denoted h , is a physical constant that is used to describe the sizes of quanta . It plays a central role in the theory of quantum mechanics , and is named after Max Planck , one of the founders of quantum theory. It has a value of approximately With eV s as energy unit: Planck's constant has units of energy multiplied by time , which are the units of action . These units may also be written as momentum times distance N m s ), which are the units of angular momentum A closely-related quantity is the reduced Planck constant (sometimes called Dirac's constant pi . This constant is pronounced as "h-bar". The figures cited here are the 2002 CODATA -recommended values for the constants and their uncertainties. The 2002 CODATA results were made available in December 2003 and represent the best-known, internationally-accepted values for these constants, based on all data available through 31 December 2002. New CODATA figures are scheduled to be published approximately every four years. Planck's constant is used to describe quantization, a phenomenon occurring in microscopic

    The fine structure constant, a 20th century mystery
    The question of how to calculate the numerical value of the fine structure constant from theory was one of the most outstandingly difficult problems in mathematical physics for the greater part of the 20th century. There were many unsuccessful attempts by researchers including famous ones such as P. A. M. Dirac to find a formula for the fine structure constant. See John Baez's website page Open Questions in Physics and also the PhysLINK website. Substantial progress with this fundamental problem is outlined on this web page. R.P.

    ... Basics: Constant Math "Constant Math" performs basic mathematical operations between the source data and a constant value within an area and the specified color channel. This operation can be applied to a single or multiple color channels at the same time. In the case you want to choose more than one channel, you can press the "Shift" key while selecting or deselecting a channel. The following mathematical operations (modes) are available:
    • "Set" replaces each pixel by the specified constant.
    • "Add" adds the constant to the source.
    • "Subtract" subtracts the constant from the source image.
    • "Difference" calculates the absolute value of the difference between the constant and the source.
    • "Multiply" multiplies the source by the constant.
    • "Min" replaces each pixel value by the minimum of the constant and the source.
    • "Max" replaces each pixel value by the maximum of the constant and the source.
    Some of the modes offer the option "...with Saturation". In this case the resulting pixel value is clipped at the maximum or minimum allowable value. However, in some cases it may be useful to disable clipping, e.g. in the case of operations in the "Hue" channel. As constant value you can specify a number with an integer and a fractional part. In the case of 8 bits pixel depth only the integer part is considered, and if you deal with 16 bits per channel, the fractional part is also considered.

    ... Search within this book at Google Print Among the myriad of constants that appear in mathematics, p, e, and i are the most familiar. Following closely behind is g, or gamma, a constant that arises in many mathematical areas yet maintains a profound sense of mystery. In a tantalizing blend of history and mathematics, Julian Havil takes the reader on a journey through logarithms and the harmonic series, the two defining elements of gamma, toward the first account of gamma's place in mathematics. Introduced by the Swiss mathematician Leonhard Euler (1707-1783), who figures prominently in this book, gamma is defined as the limit of the sum of 1 + 1/2 + 1/3 + . . . up to 1/n, minus the natural logarithm of nthe numerical value being 0.5772156. . .. But unlike its more celebrated colleagues p and e, the exact nature of gamma remains a mysterywe don't even know if gamma can be expressed as a fraction. Among the numerous topics that arise during this historical odyssey into fundamental mathematical ideas are the Prime Number Theorem and the most important open problem in mathematics todaythe Riemann Hypothesis (though no proof of either is offered!).

    Notable Properties of Specific Numbers
    Introduction
    These are some numbers with notable properties. (Most of the less notable properties are listed here .) Other people have compiled similar lists, but this is my I think are important
    A few rules I used in this list:
    Everything can be understood by a typical undergraduate college student.
    If multiple numbers have a shared property, that property is described under one "representative" number with that property. I try to choose the smallest representative that is not also cited for another property.
    When a given number has more than one type of property, the properties are listed in this order:
    1. Purely mathematical properties unrelated to the use of base 10 (example: 137 is prime.) 2. Base-10-specific mathematical properties (example: 137 is a prime with all-prime digits) 3. Things related to the physical world but outside human culture (example: 137 is close to the reciprocal of the fine-structure constant, once thought to be exact but later found to be closer to 137.036...) 4. All other properties (example: 137 has often been given almost mystical significance due to its proximity to the fine-structure constant, most famously by Eddington)

    From the Fun Fact files, here is a Fun Fact at the Easy level:
    Kaprekar's Constant
    Take any four digit number (whose digits are not all identical), and do the following:
  • Rearrange the string of digits to form the largest and smallest 4-digit numbers possible.
  • Take these two numbers and subtract the smaller number from the larger.
  • Use the number you obtain and repeat the above process. What happens if you repeat the above process over and over? Let's see... Suppose we choose the number 3141.
    The process eventually hits 6174 and then stays there! But the more amazing thing is this: every four digit number whose digits are not all the same will eventually hit 6174, in at most 7 steps, and then stay there! Presentation Suggestions: Remember that if you encounter any numbers with fewer than has fewer 4 digits, it must be treated as though it had 4 digits, using leading zeroes. Example: if you start with 3222 and subtract 2333, then the difference is 0999. The next step would then consider the difference 9990-0999=8991, and so on. You might ask students to investigate what happens for strings of other lengths or in other bases. The Math Behind the Fact: Each number in the sequence uniquely determines the next number in the sequence. Since there are only finitely many possibilities, eventually the sequence must return to a number it hit before, leading to a cycle. So any starting number will give a sequence that eventually cycles. There can many cycles; however, for length 4 strings in base 10, there happens to be 1 non-trivial cycle, and it has length 1 (involving the number 6174).

    Geodesically reversible Finsler 2-spheres of constant curvature
    Authors: Robert L. Bryant
    Comments: 11 pages, references added, some arguments improved and exposition rearranged
    Subj-class: Differential Geometry
    MSC-class:
    A Finsler space is said to be geodesically reversible if each oriented geodesic can be reparametrized as a geodesic with the reverse orientation. A reversible Finsler space is geodesically reversible, but the converse need not be true.
    In this note, building on recent work of LeBrun and Mason, it is shown that a geodesically reversible Finsler metric of constant flag curvature on the 2-sphere is necessarily projectively flat.
    As a corollary, using a previous result of the author, it is shown that a reversible Finsler metric of constant flag curvature on the 2-sphere is necessarily a Riemannian metric of constant Gauss curvature, thus settling a long-standing problem in Finsler geometry.
