Exploration Definition and 106 Threads

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.

    A Unsolved Problems in Near Surface Geophysics

    Hi everyone, In the past when I was doing my undergrad in physics, I sometimes looked at this page for inspiration in research. However, I was unable to find a similar one for applied geophysics. Currently, my area of research is exploration non-seismic geophysics, where the focus is on near...

    Amazing 19th Century Ice Ejection During Northwest Passage Sail

    In the 19th century the British Navy tried to sail ships through the Northwest Passage. The main obstacle was that the wind would drive pack ice against the northern shore of Canada. No ship could withstand a large berg. The ships usually got stuck in the ice for years, leaving plenty of...

    History Where did ancient civilizations get their supply of iron?

    Back in the 19th century British explorers came across Eskimos who were so isolated that they'd forgotten that any other humans existed. Nevertheless they had a little bit of iron that they used to put an edge on their knives. They had no trade so where did they get it? Fortunately their...

    Is Space Exploration an Ego Trip or a Scientific Investment?

    It looks to me like no more than a huge ego trip for rich people. How much of the money spent will contribute to our knowledge of Science or Space. One image from JWST probably has more worth than the whole of this fun project. They might just as well send their money to Yemen, Ukraine or Haiti...

    NASA [NASA] Cosmological projects instead of space exploration

    NASA decided to stop *WFIRST and concentrate on Mars project (send humans to Mars). What do you think about it? In my opinion, since a lot of ventures have begun space developments such as SpaceX and this proves that rockets make money, NASA should tackle WFIRST. Generally, we cannot earn...
