This is a bit creepy, maybe creepier than the UFO in a tunnel.  


   "π also appears as the average ratio of the actual length and the direct distance between source and mouth in a meandering river. Hans-Henrik Stolum, a geologist at Cambridge University, calculated the ratio between the total length of a river to the direct distance between its source and end point.[6] He found the average ratio to be a bit larger than 3. It is actually around 3.14, which we recognize as an approximation of π. Coincidence?
Rivers have a tendency toward a loopy path. A slight bend will lead to faster currents on the outside shores, and the river will begin to erode and create a curved path. The sharper the bend, the more strongly the water flows to the outside, and in the consequence the erosion is in turn the faster.
The meanders get increasingly more circular, and the river turns around and around in semi-circles. It then runs straight ahead again, and the meander becomes a bleak branch. Between the two reverse effects a balance adapts. The process is demonstrated in Figure 4-3.
We have created a model where a fictitious river is superimposed by semicircles to represent the eventual curve of the river flow. Now by labeling the source point of the river A, end point B, the midpoints of every semicircle Mi (i=1,2,3,4), and the radius of each semicircle ri, we can check if the ratio of the length of the path of the river (C) to that of line segment AB (l) is actually π."

  1. The fitness tips for motivation we've been discussing can be very powerful if you use them. Every time you head to the bathroom, take a minute or two and turn it into your temporary personal travel fitness station. This type of exercise will increase your cardiovascular endurance, improve your flexibility, increase your muscle strength, improve your balance and can actually reduce the risk of osteoporosis.

  5. Well, as we know world is changing day by day
    and its every single move in politics, business or even entertainment world affects our lives a lot.
    I also have to wonder if the evening news shows are more interested in ratings or in reporting the
    real news. Indian business news tells about the facts that
    Indian market is most preferred by the foreign investors and
    also about various other factors like quick population growth, high economic growth, English knowledge etc.
