Excerpt from Calculated Tables of Ranges for Navy and Army Guns: With a Method of Finding the Distance of an Object at Sea
I have tried to avoid these difficulties in determining the amount of retard ation in terms of the velocity, for it is not the number of pounds of resistance a shot experiences that we wish to know, but the actual amount of retardation that this resistance causes. This I claim to have discovered, and from this I deduce the initial velocity, and, finally, the horizontal range. With regard to the time of flight of a shot, actual experiment shows it to be equal to the angle of elevation, varying, in extreme case s, a second or two from this rule. I have deduced a formula, based upon this fact, which gives the time of flight very nearly for all classes of guns, for since the theory must be discovered from the ranges, 8m. Of a gun, I believe that I am right in thus basing my calculations upon experiment. I have tried to avoid the difficulties which previous investigators have fallen into, and I think that I have succeeded in doing so, and if so, I hope that an indulgent public will not fail to appreciate it.

Paperback. Condition: New. Print on Demand. This book is a detailed scholarly analysis of the complex problem of calculating the trajectory of a projectile factoring in the resistance caused by the air. Before the publication of this book, the problem had baffled the minds of even the greatest scientific thinkers throughout history. The author has sought to demystify the subject, laying out a geometrical series to express a projectile's range, explaining how to find the retardation, initial velocity, and range of a gun, and how to determine the angle of fall and final velocity of a projectile. The author's insights have laid the groundwork for more accurate and efficient gunnery practices, which would become critically important in military and naval engagements in the years to come.
