8 times 324 = 2592 4 times 648 = 2592 2 times 1296 =2592
(1) DO 2596 ABSOLUTE (2) DO 1296 HOLY SUN ABSOLUTE (4) DO 648 UNIVERSE (8) DO 324
With in the Universe life lives on Earth with' eight master genes.
324 devided by 36 = 9

However, corruption remained a significant problem under Konaré's administration."

Posted - 07 Jun 2012 : 11:45:17 PM the best part of equations for me is how even if you can't write or solve them they still exist. or is this wrong?
Posted - 07 Jun 2012 : 10:58:44 PM BTW Lance Armstrong is a freaking MACHINE. and he loves natural health and alternative healthcare. we love him.
he maximizes the capability of the human body. type 3 at its finest.

during maximal exertion (where Q is the cardiac output of the heart, CaO2 is the arterial oxygen content, and CvO2 is the venous oxygen content. (CaO2 – CvO2) is also known as the arteriovenous oxygen difference.)
usually this^ equates to a pulse somewhere between 200-205.
I actually had the pleasure of doing this type of test in undergrad.
Measures physical fitness as determined by how much oxygen your body is able to uptake during incremental (increasing) exercise. Commonly used as a 'stress test'.
Very important in areas of increased or decreased elevation. (ie colorado)

Posted - 07 Jun 2012 : 10:25:04 PM okay. kind of an equation.
hydrangeas change color with the soil pH (depending upon the species and genotype color of said species)
Posted - 07 Jun 2012 : 8:33:41 PM Not saying I'm good at it, but it's one that I see in nature often.
work = force x distance.
My favorite though is momentum.
Suppose a bartender slides a beer across a sporadically wet bar with an average friction coefficient of 0.264, while applying 37 newtons accelerating at a rate of 2.1 meter sec squared to a glass weighing 1.3 kilograms. You're too drunk to actually catch this sliding glass of pale ale and it slides off the 14 foot long bar that is 3.174 feet high.
where does it land?
Posted - 07 Jun 2012 : 7:59:17 PM The shallow water wave equation and tsunami propagation
As we are all now very much aware, tsunamis are water waves that start in the deep ocean, usually because of an underwater earthquake (though tsunamis can also be caused by underwater landslides or volcanoes), and then propagate towards shore. Initially, tsunamis have relatively small amplitude (a metre or so is typical), which would seem to render them as harmless as wind waves. And indeed, tsunamis often pass by ships in deep ocean without anyone on board even noticing.
However, being generated by an event as large as an earthquake, the wavelength of the tsunami is huge – 200 kilometres is typical (in contrast with wind waves, whose wavelengths are typically closer to 100 metres). In particular, the wavelength of the tsunami is far greater than the depth of the ocean (which is typically 2-3 kilometres). As such, even in the deep ocean, the dynamics of tsunamis are essentially governed by the shallow water equations. One consequence of these equations is that the speed of propagation of a tsunami can be approximated by the formula
where is the depth of the ocean, and is the force of gravity. As such, tsunamis in deep water move very fast – speeds such as 500 kilometres per hour (300 miles per hour) are quite typical; enough to travel from Japan to the US, for instance, in less than a day. Ultimately, this is due to the incompressibility of water (and conservation of mass); the massive net pressure (or more precisely, spatial variations in this pressure) of a very broad and deep wave of water forces the profile of the wave to move horizontally at vast speeds. (Note though that this is the phase velocity of the tsunami wave, and not the velocity of the water molecues themselves, which are far slower.)
As the tsunami approaches shore, the depth of course decreases, causing the tsunami to slow down, at a rate proportional to the square root of the depth, as per (1).
