    en.wikipedia.org/wiki/Prospecting

    Although these are thought of as "old" prospecting methods, these techniques are still used today, but usually coupled with more advanced techniques such as geophysical magnetic or gravity surveys. In most countries in the 19th and early 20th century, it was very unlikely that a prospector would retire rich even if he was the one who found the ...

    en.wikipedia.org/wiki/History_of_chemistry

    The protoscience of chemistry, and alchemy, was unsuccessful in explaining the nature of matter and its transformations. However, by performing experiments and recording the results, alchemists set the stage for modern chemistry. The history of chemistry is intertwined with the history of thermodynamics, especially through the work of Willard ...
