How to Disable Volume Button Controls on iPhone. You can try it out yourself by pressing the volume buttons, they will no longer impact the ringer or alert levels at all, though they will continue to change the volume of things like app, games, and playing videos.
Uniformitarianism - James Hutton and Sir Charles Lyell The doctrine of Uniformitarianism was significantly advanced by James Hutton (1726-1797) in his publication, Theory of the Earth (1785). Hutton influenced Sir Charles Lyell (1797-1875), who is acclaimed as the father of modern geology with his work, Principles of Geology (1830-1833, a three volume work).
The principle of uniformitarianism - processes operating in the past were constrained by the same laws of physics as operate today. Note that these are principles. In no way are they meant to imply there are no exceptions. For example, the principle of superposition is based, fundamentally, on gravity. In order for a layer of material to be deposited, something has to be beneath it to support it. It can't float in mid-air, particularly if the material involved is sand, mud, or molten rock. The principle of superposition therefore has a clear implication for the relative age of a vertical succession of strata. There are situations where it potentially fails -- for example, in cave deposits.
