41. New Mathematical Constant Discovered

New Mathematical Constant Discovered
Descendent of Two Thirteenth Century Rabbits
A recent mathematical result by Divakar Viswanath, a young computer scientist at the Mathematical Sciences Research Institute (MSRI) in Berkeley, California, has put the Fibonacci numbers back in the news and shown a connection between rabbits and the number 1.13198824 . . . . Most popular expositions of mathematics mention the Fibonacci sequence, usually observing that the Fibonacci numbers arise frequently in nature. For example, if you count the number of petals in various flowers you will find that the answer is often a Fibonacci number (much more frequently than you would get by chance). For instance, an iris has 3 petals, a primrose 5, a delphinium 8, ragwort 13, an aster 21, a daisy 34, and michaelmas daisies 55 or 89 petals all Fibonacci numbers. For another example from the botanical world, if you look at a sunflower you will see a beautiful pattern of two spirals, one running clockwise, the other counterclockwise. Count those spirals and you will find that there are 21 running clockwise and 34 counterclockwise both Fibonacci numbers. Similarly, pine cones have 5 clockwise spirals and 8 counterclockwise spirals; and the pineapple has 8 clockwise spirals and 13 going counterclockwise. One further example concerns the way the leaves are located on the stems of trees and plants. If you take a look, you will see that, in many cases, as you progress up along a stem, the leaves are located on a spiral path that winds around the stem. The spiral pattern is sufficiently regular that it leads to a numerical parameter characteristic for the species, called its divergence. Start at one leaf and let

Authors: Jonathan Sondow (Submitted on 8 Nov 2002 ( ), last revised 14 Jun 2004 (this version, v3)) Abstract: We give analogs for Euler's constant and ln(4/Pi) of the well-known double integrals for zeta(2) and zeta(3). We also give a series for ln(4/Pi) which reveals it to be an "alternating Euler constant."

we can be confident it is more correct. Sad about other compilers - this is the
snag with this representation of constants - it stresses compilers.
It is up to the compiler what it provides for long double - C++ says it must

    Direct Variation
    When two variables are related in such a way that the ratio of their values always remains the same, the two variables are said to be in direct variation. In simpler terms, that means if A is always twice as much as B, then they directly vary. If y varies directly as x, the graph of all points that describe this relationship is a line going through the origin (0, 0) whose slope is called the constant of the variation. That's because each of the variables is a constant multiple of the other. Let's review several areas of direct variation. 1) Expressing Direct Variation an an Equation The equation y/x = 6 states that y "varies directly as" x since the ratio of y to x (also written y : x ) never changes. The number 6 in the equation y/x = 6 is called the constant of variation. The equation y/x = 6 can also be written in the equivalent form,
    y = 6x. That form shows you that y is always 6 times as much as x.

The 8.5" x 11" paper rectangle has an area of 93.5 in , but what about its perimeter? Consider the family of rectangles that have, not a constant area, but a constant perimeter, and answer these questions:
  • Make at least 8 physical models of "baseless" cylinders from rectangles with perimeters of 39". You may cut the physical models from paper, draw two-dimensional versions (as in our drawing above), or choose some other method.
  • For the rectangles with constant area, there were no limits on the height of the cylinder: in theory, the cylinders could become infinitely tall and infinitely narrow, or infinitely short and infinitely stout. Is this also true of the family of cylinders with fixed perimeter? Explain.
  • Remember your observation about the cylinders with a constant area: as the cylinders get taller and narrower they hold less, and as they get shorter and stouter they hold more. Through the following exploration, decide whether this is true for constant perimeter as well. (You may need the formula

      Another fundamental constant accused of changing
      Cosmologists claim to have found evidence that yet another fundamental constant of nature, called mu , may have changed over the last 12 billion years. If confirmed, the result could force some physicists to radically rethink their theories. It would also provide support for string theory, which predicts extra spatial dimensions. Speed of light may have changed recently The ratio of a proton's mass to that of an electron, known as mu , is among the most mysterious of constants. There is no explanation for why the proton's mass should be 1836 times that of the electron. The constant governs the strong nuclear force, which holds protons and neutrons together in atomic nuclei, and is also responsible for binding the quarks - the building blocks which make up protons - neutrons and most other fundamental particles.

    Stressed Out
    Slope as Rate of Change
    It's the night of the big game (or play). You're in the locker room (or dressing room). The coach (make that director) is pumping the team (cast) up. "Now, I know you people are nervous. That's okay, in fact, that's what we want. You're going to perform better on the court (stage) if you're a little nervous". Does the graph above confirm what the coach (director) told you? Here are some questions for you based upon the graph.
  • Write a statement that describes performance as stress increases.
  • Which part of the graph illustrates where stress is highest? What is performance at that point? Which part of the graph illustrates where performance is highest? Which part of the graph illustrates where performance is increasing? Which part of the graph illustrates where performance is decreasing?
  • Notice that the graph is symmetric about a vertical line. What would you say this indicates about performance?
  • What if this were a graph of your bank balance over a year. Describe what the graph would indicate about your saving and spending practices. Slope as Rate of Change There is a direct relation between the rate of change of a function and the slope of its lines.
