What is Exploration: Definition and 105 Discussions

Exploration is the act of searching for the purpose of discovery of information or resources. Exploration occurs in all non-sessile animal species, including humans. In human history, its most dramatic rise was during the Age of Discovery when European explorers sailed and charted much of the rest of the world for a variety of reasons. Since then, major explorations after the Age of Discovery have occurred for reasons mostly aimed at information discovery.

    An Exploration of Unified Theories

    I am starting this thread with an observation and three questions. I post this only as a starting point. I would appreciate any comment on the search for a unified theory. I am an amateur physicist at best, yet it often seems as though the scientific world over complicates the search for...

    Motion of Source Effects Frequency of Wave: an Exploration

    i know that motion of source can change the frequency of wave. constant speed motion will not change the wave progagation relative to water itself.but from the point of a observer at speed 0, the propagation speed will change. so my question is what will happen to frequency? thanks for help...
