Later, as the months wear on, a series of additional messages arrive from Gerry -- always delivered in the most remarkable and surprising of ways. With each new message comes a new adventure, and each letter signs off in the same familiar way: P.S. I love you..
For a person standing at sea level, however, the horizon is only about 3 miles away. Lets do the calculations. The figure below shows an observer whose eyes are a distance E above sea level. A straight line drawn from the observers eyes tangent to the seas surface touches it at the distance d1, which is the distance to the horizon. If R is the radius of the earth, then, to first order in E/R, it is easy to show that.
1.17 times the square root of your height of eye = Distance to the horizon in nautical miles. Quizmonster. If you're standing at the water's edge, the horizon is about 3 miles away.If you click here that will link you to a web-page which has a handy computer version that helps you work it out.All you do is put the height of your eye relative to the water's edge into the slot and click on 'Compute'.sing this, the distance to the horizon is: SQRT (h+2rh). Using feet throughout (for a six foot eye height) the calculation becomes: SQRT (6+(2*21120000*6) = 15920 feet. Divide this by 5,280 (feet in a mile) and you get 3.01 miles. matt_london s formula is a boiled down version of this one.
