	Kerry's team thinks they have found the Missing Link. One likes pinto beans and bar-b-q, the other digs bananas and flinging poo! Yet, they both seem to share some startling similarities. Is their theory right or is this just more hype from the very far left? Author: Free Web Games| Date: 10-01-2005 | Size: 560 KB

	Dark Solar System  License: Freeware
	In cosmology, dark energy is a hypothetical form of energy which permeates all of space and has strong negative pressure. According to the theory of relativity, the effect of such a negative pressure is qualitatively similar to a force acting in opposition to gravity at large scales. Invoking such an effect is currently the most popular method for explaining recent observations that the universe appears to be expanding at an accelerating rate, as well as accounting for a significant portion of the missing mass in the universe. Two proposed forms for dark energy are the cosmological constant, a constant energy density filling space homogeneously, and quintessence, a dynamic field whose energy density can vary in time and space. Distinguishing between the alternatives requires high-precision measurements of the expansion of the universe to understand how the speed of the expansion changes over time. The rate of expansion is parameterized by the cosmological equation of state. Measuring the equation of state of dark energy is one of the biggest efforts in observational cosmology today. Adding a cosmological constant to the standard theory of cosmology (i.e. the FLRW metric) has led to a model for cosmology known as the Lambda-CDM model. This model agrees closely with established cosmological observations. As NASA reports indicate, 70 percent or more of the universe consists of dark energy, about which we know next to nothing. At the beginning of March, 2006 the satellite of China National Space Administration, DARKSTAR started operations, observing in neutrino the solar corona. It results a sensational information that our system also contains dark energy. This substance is located within the solar surface. We have placed above cosmological information into our screensaver and you can view allocation of dark matter in our Solar system! Author: Icon Empire| Date: 31-03-2006 | Size: 539 KB

	Gravitational Lensing  License: Freeware
	Einstein's General Theory of Relativity demonstrates that a large mass can deform spacetime and bend the path of light. So, a very massive object, such as a cluster of galaxies can act as a gravitational lens. With this program, one can draw images to see the effect of gravitational lensing. You can easily test the effects of several parameters by changing them and redrawing the image. Author: Wouter Dhondt| Date: 24-05-2002 | Size: 75 KB

	Orneta Biorhythm for Smartphone 2002  License: Freeware
	Orneta Biorhythm provides a simple and easy way to track your daily emotional, intellectual and physical states from a Windows Mobile based Smartphone. Everything that happens in nature is cyclic. Biorhythm Theory states that each person is influenced by three biological cycles, physical, emotional and intellectual, which begin at birth and continue throughout our lives. To compute a person's biorhythm for a given day, all you need is their date of birth plus the correct mathematical calculations. We are influenced by the changing of the seasons, the lunar tides, day and night, etc. Even the human body is influenced by these factors, which are known as biorhythms. With Orneta Biorhythm you can now draw biorhythms in your MS Smartphone! Orneta Biorhythm Features Analyze your emotional, intellectual and physical biorhythm readings Display only the reading you want, one two or all three Find out upcoming critical, zero, minimum and maximum cycles Compare your biorhythm to that of another individual Author: Orneta| Date: 28-05-2003 | Size: 47 KB

	Smart Gambler's Calculator for PocketPC OS  License: Freeware
	Smart Gambler's Calculator allows one to calculate the main parameters for fixed-size and fixed-fraction betting. The main input parameters are grouped into several groups. The first group contains data about the properties of a single bet: probability of winning the bet, and the payoff (prize-to-bet ratio). The second group contains parameters of the gambler's "comfort zone": bankroll, number of games to play (or number of bets to place), and desired profit or prize-to-win in these games/bets. The calculator shows the expected value (profit/lose in the long run) and standard deviation (variability) of this gambling or investment opportunity. For the fixed bet, the probabilities of reaching the goal and of losing the bankroll are calculated. For the fixed-fraction betting strategy, the optimal fraction (percentage) of bankroll is determined. In contrast to Kelly's system, in which it is assumed that a player is a risk-averse person (so not a gambler) and which is applicable only to games with positive expected values, this system has none of these restrictions. The optimality is determined in the following way. First of all, the optimal fixed-fraction bet should minimize the probability of ruin. In theory, if money were "infinitely divisible," the probability of ruin in fixed-fraction betting is zero. The second objective/criterion is to maximize the probability of reaching the established goal, and the third objective/criterion is to maximize the expected value of the player's bankroll, subject to restrictions set by the previous criteria.
