Extractions: PROOF OF RIEMANN'S HYPOTHESIS James Constant math@coolissues.com Riemann's hypothesis is proved using Riemann's functional equation. Introduction The famous conjecture known as Riemann' s hypothesis is to classical analysis what Fermat's last theorem is to arithmetic. Euler (1737) noted that the formula the sum extending to all positive integers n, and the product to all positive primes p. The neces- sary conditions of convergence hold for complex values of s as a function of of the complex variable s , Riemann (1859) proved that satisfies a functional equation which led Riemann to the theorem that all the zeros of , except those at s=-2,-4,-6, . . . , lie in the strip of the s -plane for which where x is the real part of s . Riemann conjectured that all the zeros in the strip should lie on the line x = ½. Attempts to prove or disprove this conjecture have generated a vast and intricate department of analysis, especially since Hardy (1914) proved that has an infinity of zeros on x The question is still open in 2000. A prize is available to prove or disprove Riemann's hypothesis. Proof Using Riemann's Functional Equation It has already been shown that all zeros are in the critical strip and that they are symmetric about the critical line x Riemann's functional equation can be restated as =A( in which A( at all points in the critical strip.

Extractions: Formulation of the Gaia Hypothesis Web Publication by Mountain Man Graphics, Australia in the Southern Autumn of 1996 In the search for the evidence of extra-terrestrial life, the closer - Earth's neighbouring planets - Venus and Mars were targetted by the NASA program. Of these, due to the unknown conditions of the planetary surface caused by the dense and aggitated Venusian atmosphere, the planet Mars was given priority. The first spacecraft to visit Mars was Mariner 4 in 1965, and several others followed including the two Viking landers in 1976. Dr James Lovelock, a British Chemist specialising in the atmospheric sciences, was a recognised leader in his field. He was to invent an electron capture detector, capable of tracing extremely small amounts of tracer elements in gases, which was used by the ozone monitoring research concerning the effect of CFC's in the early 1970's. Almost a decade before this, NASA and the Jet Propulsion Laboratory (JPL) requested the presence of Lovelock in their project teams relating to the scientific search for the evidence of life on Mars. In collaboration with other project researchers, Lovelock predicted the absence of life on mars based on the consideration of the Martian atmosphere and its state of being in a chemically

Extractions: It is a review (published in 1989) of James Lovelock's The Ages of Gaia What is the hypothesis of Gaia ? Stated simply, the idea is that we may have discovered a living being bigger, more ancient, and more complex than anything from our wildest dreams. That being, called Gaia, is the Earth. More precisely: that about one billion years after it's formation, our planet was occupied by a meta-life form which began an ongoing process of transforming this planet into its own substance. All the life forms of the planet are part of Gaia. In a way analogous to the myriad different cell colonies which make up our organs and bodies, the life forms of earth in their diversity coevolve and contribute interactively to produce and sustain the optimal conditions for the growth and prosperity not of themselves, but of the larger whole, Gaia. That the very makeup of the atmosphere, seas, and terrestrial crust is the result of radical interventions carried out by Gaia through the evolving diversity of living creatures. Encountering the Earth from space, a witness would know immediately that the planet was alive. The atmosphere would give it away. The atmospheric compositions of our sister planets, venus and mars, are: 95-96% carbon dioxide, 3-4% nitrogen, with traces of oxygen, argon and methane. The earth's atmosphere at present is 79% nitrogen, 21% oxygen with traces of carbon dioxide, methane and argon. The difference is Gaia, which transforms the outer layer of the planet into environments suitable to its further growth. For example, bacteria and photosynthetic algae began some 2.8 billions of years ago extracting the carbon dioxide and releasing oxygen into the atmosphere, setting the stage for larger and more energetic creatures powered by combustion, including, ultimately, ourselves.

Extractions: RIEMANN HYPOTHESIS Some numbers have the special property that they cannot be expressed as the product of two smaller numbers, e.g., 2, 3, 5, 7, etc. Such numbers are called prime numbers, and they play an important role, both in pure mathematics and its applications. The distribution of such prime numbers among all natural numbers does not follow any regular pattern, however the German mathematician G.F.B. Riemann (1826 - 1866) observed that the frequency of prime numbers is very closely related to the behavior of an elaborate function z (s) called the Riemann Zeta function . The Riemann hypothesis asserts that all interesting solutions of the equation z (s) = lie on a straight line. This has been checked for the first 1,500,000,000 solutions. A proof that it is true for every interesting solution would shed light on many of the mysteries surrounding the distribution of prime numbers.

Biology 202 On Serendip Schizophrenia is a disease that has plagued societies around the world for centuries, although it was not given its formal name until 1911. It is characterized by the presence of positive and negative symptoms. Positive symptoms are so named because of the presence of altered behaviors, such as delusions, hallucinations (usually auditory), extreme emotions, excited motor activity, and incoherent thoughts and speech. In contrast, negative symptoms are described as a lack of behaviors, such as emotion, speech, social interaction, and action.
Cogprints - The Sexual Competition Hypothesis For Eating Disorders
A hypothesis that suggests eating disorders stem from intense female intrasexual competition for mates.
http://cogprints.soton.ac.uk/documents/disk0/00/00/08/00/index.html

Extractions: HTML A hypothesis is presented for eating disorders that contends that these syndromes together with the phenomenon of the pursuit of thinness are manifestations of female intra-sexual competition. It is argued that the present-day environment of Western coutries presnts a range of conditions that have led to the overactivation or disruption of the archaic female sexual strategy of maximising 'mate value'. The hypothesis deals with the ultimate level of causation and is therefore compatible with a range of theories dealing with the proximate level of causation.

Abstract: A new hypothesis is presented within the framework of evolutionary psychology that attempts to explain the origins of obsessive-compulsive disorder. It is suggested that obsessions and compulsions originate from the overactivity of a mental module that the majority of humans possess and has the function of generating risk scenarios without voluntary intervention. It is hypothesised that obsessional phenomena function as an off-line risk avoidance process, designed to lead to risk avoidance behaviour at a future time, thus distinguishing it from anxiety and related phenomena as

The Two Source Hypothesis
Summary of the dominant synoptic theory by Stephen Carlson.
http://www.mindspring.com/~scarlson/synopt/2sh/index.htm

Extractions: Mark was a source for Matthew and Luke, both of whom also independently used a now lost sayings source called Q. The Two Source Hypothesis ( ) has been the predominant source theory for the synoptic problem for almost a century and half. Originally conceived in Germany by Ch. H. Weisse in 1838, the came to dominate German protestant scholarship after the fall of the Tübingen school with H. J. Holtzmann's endorsement of a related variant in 1863. In the latter part of the 19th century, the Oxford School brought the to English scholarship, culminating in B. H. Streeter's 1924 treatment of the synoptic problem. Now, the commands the support of most biblical critics from all continents and denominations. The derives its name from its postulation of two main sources for the synoptic gospels: a narrative source for the triple tradition and a sayings source for the double tradition. The triple tradition comprises the subject matter jointly related by Matthew, Mark, and Luke. Generally, the triple tradition is characterized by substantial agreements in arrangement and wording among all three gospels with frequent agreements between Mark and Matthew against Luke and between Mark and Luke against Matthew, but a near absence of agreements of Matthew and Luke against Mark.

This function extends to points with real part s less than or equal to one by the formula (among others) The contour here is meant to indicate a path which begins at positive infinity, descends parallel to and just above the real axis, circles the origin once in the counterclockwise direction, and then returns to positive infinity parallel to and just below the real axis.

http://www.stat.sc.edu/~ogden/javahtml/power/power.html

Extractions: This applet illustrates the fundamental principles of statistical hypothesis testing through the simplest example: the test for the mean of a single normal population, variance known (the Z test). The basic set-up of the test is this: using only n independent observations from a normal distribution with unknown mean (but known variance), the task is to decide whether to accept a null hypothesis for a specified value of , or to reject the null hypothesis in favor of some alternative hypothesis. In most applications, there are only three alternative hypotheses of interest: respectively, ``upper-tailed,'' ``lower-tailed,'' and ``two-tailed.'' The testing framework consists of computing a ``test statistic'' and then rejecting the null hypothesis if the appropriate condition is satisfied. In the order the alternative hypotheses are given above, the null hypothesis is rejected if where represents the upper critical point of the standard normal distribution. This hypothesis testing procedure is set up to give the null hypothesis ``the benefit of a doubt;'' that is, to accept the null hypothesis unless there is strong evidence to support the alternative.
