Most flowerheads on a field of blooming sunflowers are turned towards the east, where the sun rises each morning. Immature sunflowers in the bud stage exhibit heliotropism; on sunny days the bud tracks the sun on its journey along the sky from east to west, while at night or at dawn it returns to its eastward orientation. The motion is performed by motor cells in the pulvinus, a flexible segment of the stem just below the bud. The stem stiffens at the end of the bud stage, and when the blooming stage is reached the stem freezes in its eastward direction. Thus, blooming sunflowers are not heliotropic anymore, even though most flowerheads are facing the direction where the sun rises.

This is a question which the scientific community cannot answer. The answere lies with those who are close to thier religions.

I dont think there is any scientific reason for that. It is just a myth. Lot of people spread this hype. It is BS.

The US Marine Corps has this down to a science.  I suggest that if you ask one of their recruiters you will be amazed at the detailed answer.

You just got your basic wrong. Try to reveal them again, and understand the ground physics first...\n\nThis webpage may help you to have preliminary understanding...\n\nhttp://computer.howstuffworks.com/hard-disk.htm

they have a high specific heat capacity,\nBecause it takes a lot of energy to make them increase in temperature.
